Need Electrostatic Precipitator Spares? Know The Common Components

For someone not aware of the term yet, Electrostatic Precipitator or ESP is basically a filtration device which helps in controlling emissions of minute particles in industries. Their primary task is to use induced electrostatic charge to remove fine particles from flowing gas. Approach any electrostatic precipitator manufacturer and choose from a wide range of equipment according to your requirement. Whatever is the size and design of your ESP, there are a few common components a majority of these models contain. They are known as spare parts.

5 Basic Components Or Spare Parts Of Electrostatic Precipitator

  • Discharge And Emitting Electrodes

This is regarded as the most vital component of the device as it affects its performance. The discharge electrodes are generally fabricated from annealed copper wire tubes of smaller diameter. They can generate high corona as the welded wires vertically hang in the electrode. They generate electrical fields of ionize and high power flue gas.

  • Collecting Electrodes

Sheet metals are generally used to manufacture this component. The negatively charged particulate matter is attracted by the surface and so one can easily use them to treat gases of large volumes. Some of them are designed in such a way so that they can collect particulate matter with higher efficiency.

  • Insulators

Insulators help in mechanically discharging electrodes and isolating them. They are generally used in ground casings as they are the high voltage systems of the device. They are specially designed so that they can back the load of the electrodes. Non-conducting materials are used to make them which make them durable.

  • Hopper Discharge Systems

This is one of the most important Electrostatic Precipitator Spares as it helps in removing the dust collected in the hopper. The functioning of your hopper discharge system can either be automatic or manual. The dust is collected through electrostatic discharge which helps in cleaning the hopper within the shortest span of time.

  • Rapper Coils

If you are willing to get rid of the dust from emitting and collecting electrodes, the rapper coils are exactly the components you need. They can deliver shear forces with huge strength. The electrodes are hit at fixed time intervals which dislocates the dust particles. You can adjust the rapping intensity according to your requirement.

Since you are now aware of the common components of an Electrostatic Precipitator, it’s time you change the faulty parts with new ones or change the device entirely.

A few important facts about electrostatic precipitators

You may have heard about different types of useful technologies to ensure air purification. UV light, fibreglass or HEPA filters, activated carbon and a lot more. Each of them uses a specific strategy to remove particles and thus purify the air. Electrostatic precipitators are technologies for air purification mostly used to clean industrial fumes though now they are used for residential air as well.

Let’s have a quick look at some important points to know about an electrostatic precipitator.

Basic working principles

Basically, this helps to purify the air by means of electrostatic force for grabbing and holding dust as well as other particles. The tool consists of wires and collection plates along with high voltage through an electrostatic field between wires and collecting plates to charge the air electrically while ionizing them during the process. While airborne particles like pollen or dust flow between the plates, those particles become charged and that causes them to get attached to the plates. And then the air flows through leaving those particles behind. The entire process results in clean and purified air. Particles collected in the plate are shaken loose and then scraped off or washed away. This process ensures disposal of airborne particles in an eco-friendly manner.

Electrostatic precipitation is a highly organised method for filtration of fine particles from sinuous gas. Such precipitators are able to manage a large quantity of air without causing significant slowing down in the flow rate. However, while choosing an electrostatic precipitator (ESP), you must keep in mind the purpose of buying it. For example, the ESP used for kitchen must be different from the one used in industrial units. Extraction of air from the kitchen is a complex process as this air is a complicated compound mixture of grease, smoke, water vapour and temperature. So for your kitchen, you should choose one that is explicitly designed for kitchen environment instead of a non-specific industrial ESP.

Types of an electrostatic precipitator

Mainly two types of electrostatic precipitators are available in the market. They provide different levels of air purification. Let’s have a look at how they work.

  • Plate precipitators – This is the most common type of ESP. This contains a row of vertical wires that provide the particles with a charge while the collecting plates collect and hold the particles. This basic, two-stage design (first charging and then collection) ensures reduced ozone production that can be otherwise harmful if inhaled. This type of ESP is specifically beneficial for those working in close proximity to the device.
  • Wet precipitators – This is another widely used type of precipitator. This is also called a WESP or a Wet Electrostatic Precipitator. This device is mostly used for removal of liquid droplets like sulfuric mist from the industrial steam. WESP uses a typical tubular design to let the collected particles and moisture form a thick combination. This model comes really handy for content holding a huge quantity of moisture or containing combustible particles.

Benefits

  • Ensures up to 99 percent molecule removal
  • Minimum pressure drop
  • Collected particles may be improved for further processing

Discussed above are some important factors that you must know before using an electrostatic precipitator.

Know More About Electrostatic Precipitators And Its Control Techniques

The easiest way to remove particles from a gas stream is by using an electrostatic precipitator. Electrical energy is used to charge those particles negatively or positively before they get attracted by the collector plates which are generally of the opposite charge. The collected particles become dry in the collector plates and can be easily removed or washed with water. Not everyone using the procedure is aware of the fact that the collection efficiency of ESPs is more than 99 percent and this is why they are widely used in various industries.

Its Various Components

The four common components you will generally find in an electrical precipitator are discharge electrodes, rappers, collection surfaces and gas distribution plates. These plates comprise of numerous plates which are perforated to maintain and properly distribute the air entering the gas stream.

The discharge electrodes in a majority of the ESPs are divided into 3 or 4 fields. The larger electrodes are divided into around 14 fields which are generally found in series. A solo transformer-rectified set power supply is sufficient to energise those electrodes and create ions. The ions dashes with the particles in the incoming gas stream and applies an electrical charge. The charged particulate matter then collects on the plates or pipes which can be later removed using the rapping system.

Types Of Electrostatic Precipitators

There are generally two types of ESPs, namely dry ESPs and wet ESPs. What differentiates these two is the method through which the plates where the particles collect are cleaned. Vibrations or mechanical impulses are used to loosen the collected particulate matter and clean the dry ESPs from the collection plate. To remove wet ESPs, you have to rinse the collector plate thoroughly using water. Using this wet method becomes necessary when the particles accumulated in the gas streams are sticky and have low resistivity.

ESP Performance And Particle Resistance

For someone not aware of the term, ‘particle resistivity’ is basically the property of the particles that can influence the process through which they deposit or is removed from the collection plates. This is why resistivity of the particles can affect the performance of Electrostatic Precipitators drastically. Moderate resistivity is regarded to be the ideal situation when the particles can automatically accomplish some of their charges after reaching the collection plate. This prevents the inhibition of other deposited particles and makes them capable of retaining their charge while holding them lightly on the plate.

It takes longer for the particles to conduct away their charge if the resistivity of the particles is higher. As a result, a negative charge builds up on the plate which inhibits the other deposits. If the resistivity is too low, the particles will start losing their own charge once they reach the collection plate and start attracting charges from the plate. This will make the negatively charged particles deter back into the gas stream.

Since your knowledge about electrostatic precipitators has enhanced, it’s time you start looking for a reliable company who can take care of all your ESPs needs.

Electrostatic Precipitator, Its applications, Advantages, at Industrial Zones in India

According to world Health Organisation 2015 report, around 7 million premature deaths take place due to air pollution.

And 10 thousand people are dying at the age of around 40 because of toxic fumes. Thousands of children become asthma patients at the age of six only.

And according to a forecast according to the Constance growth of dying, by the year of 2050, there must be a scarcity of pure drinking water due to the lack of sanitation.

The most air polluted “hotspots” have been found in the biggest metropolitan cities, rather can say, the industrial areas of the most metropolitan cities in this country.

According to another statistical report air has been polluted due to cheap and poor quality supply of coal in most industrial areas. And this leads to India being  one of the leading pollutant regions in the whole universe.

Contributions of Industrialisation in Causing Global Warming and Its Effects

Undoubtedly, global warming is the growing concern of the environmentalists. Actually, it is the increase of earth’s average surface temperature and is caused by the effect of the greenhouse gases which absorb heat.

A report of EPA( Environmental Protection Agency) showed that the temperature of the earth has increased by 0.8% in the past few years. It has been caused by the increasing rate of deforestation, industrialisation and pollution.

Our world witnessed the industrial revolution in the year 1700 and then it spread to the rest of the world. The introduction of the machinery and factories has given birth to mass production that caused various kinds of environmental hazards.

Industrialisation has caused the depletion of the environment, leaving it permanently damaged. An example of the depletion is the loss of forests. It not only uproots the wildlife, but also it affects the quality of the air. Due to lack of trees, the oxygen is generated in less amount. Moreover, the places of the forests are captured by the industries that emit greenhouse gases like carbon dioxide and methane.

The Effects of Global Warming

  • Apart from increasing the temperature, there are several other negative impacts of global warming. Among them, the rise of the sea level is a threatening impact. As the temperature increases, the glaciers are melting causing a massive sea level rise. It is one of the reasons of hurricanes, Tsunamis, tornados etc.
  • The extreme weather change caused by global warming has given birth to forest fires, heat waves and several other tropical storms. It has also made the coral reefs suffer from the worst bleaching. Even, the reefs have witnessed the highest dying record in the last few years.
  • Global warming increases smog pollution and causes pollen allergies and asthma. Studies have showed that the increasing level of carbon dioxide gives birth to weeds like ragweed that causes allergies and asthma. In recent years, the number of people suffering from asthma has increased and global warming can be made responsible for that.

  • Warmer temperatures help to increase the amount of rainfall in some areas. Even, it can increase the frequency of rainstorms that can put many people at risk of floods. The warm environment can also increase the possibility of drought and can affect the agriculture.
  • The increasing temperatures are also responsible for damaging the balance of the ecosystems. There are a good number of species that are becoming extinct as they are unable to adapt the conditions. A recent report showed that more than 1 million species would be eliminated by before 2050 if the current environmental conditions continue.

So, it can be concluded that global warming leaves a strong impact on our environment. As the temperature continues to increase, it is difficult to foretell what more negative impacts global warming will leave. It can be said that the situation is going to be worse, if necessary steps are not taken now. It is up to everyone to recognise the problems and take preventive measures.

Electrostatic Precipitator – To a Smokeless Mother Nature, with Love

The earliest date attempt of filtering suspended particles from gases and aerosols was first made by a scientist named Dr. Frederick Cottrell in the years 1906. The invention of the device, thus, is a result of this man’s attempt and the world owes to him big time. Evidence for his work is the US Patent 895, 729, which was filed in 1097 stating the work.

The patent described how suspended particles could be removed from every kind of industrial fume, smoke, and dust using high voltage electrodes. An interesting part of Cottrell’s patent reveals how the technique can be used for the destruction of fog and mist on land and also in water.

How does this device work?

Dirty flue gas is allowed to pass through two electrodes in the electrostatic precipitator. These electrodes are wrapped in metal wires and placed inside a pipe. The receiving electrode is negatively charged and the emitting electrode is positively charged.

The particles in the flue gas that passes through the device are attracted by the negative charges and attain the negativity. These particles are then attracted by the positively charged electrode due to their difference in charges. What comes out is only clean, fresh air.

The particles are removed using collecting plates at regular intervals via shaking, brushing, or automated cleaning processes like rapping. Some devices have additional fabric filters, which help in the removal of large-size soot particles.

Why is static electricity effective on smoke?

No matter how strongly you support the notion that smoke is gas, the fact cannot be denied that it is an aerosol. Yes, most aerosols contain liquid droplets. You’ve seen them in perfumes and air fresheners.

But, smoke as an aerosol contains soot particles instead. Whatever be it, smoke is liable to the influence of static electricity. These particles can be charged and removed from the flue gas. The high voltage which is applied can ionise the particles and separate them from the source.

What are the types of electrostatic precipitators available in the market?

The designs vary in the sense that they can separate particles of different size and chemical make-up from different volumes and types of flue gas. For instance, if a power plant burns excessive coal, the device has to be designed keeping in mind the chemical composition of the same.

Yet again, there are power plants that need to lower the emission of sulphur dioxide and ash which are generated during production processes. Devices for this purpose should be upscale in size.

Further, it also depends on the law of the area in which the device is being used. If the rules for air pollution control are very stringent, power plants running in the area might require multiple devices working simultaneously to clean air.
Lastly, the accessories are important, too. For instance, if your factory processes demand a huge amount of dust and smoke to be cleaned at frequent intervals, the device must be designed in such a way that it supports automated rapping systems.

What are the typical applications of the device?

• Gas production plants.
• Cement and limestone production plants.
• Iron and steel production plants.
• Chemical and metallurgical production plants.
• Coal boilers.
• Biomass fired boilers.
• Sludge incinerators.

The end story is, if there’s a device that can keep industrial air pollution under control, it definitely has to be an electrostatic precipitator. It’s efficacious, economical, and very much advantageous. It’s an invention devised exclusively for Mother Nature with love.

Electrostatic Precipitator Spares – Effective Way to Purify Environment

Electrostatic Precipitator Spares is used to reduce the pollution from the chimneys or channels. It is usually used in thermal power plants to control the pollution level.

electrostatic precipitatorElectrostatic Precipitator was first discovered by Dr F.G. Cottel in 1906 and was first used in1937 to remove dust particles. They are widely used for removing flue ash from electric utility boiler emissions. It is gaining huge popularity in recent times because of the rules of stringent air quality codes. It is designed in such a way that it can be used as a primary or supplementary unit to a cyclone collector. It is considered valuable to keep cyclone as a primary collector for cases where compilation in effectiveness must be improved specifically when there is a large amount of unburnt carbon as enormous quantities can unfavorably influence the assortment effectiveness of a precipitator.

There are numerable benefits of electrostatic precipitator spares. Some of them are mentioned below-

  • It is very effectual in removing tiny particles such as fly ash, smoke and mist. It has the capability of removing dust adequately large ranging from 0.01 micron to 1.00 micron. The diminutive dust particles which are below 10 microns cannot be detached even with the assistance of wet scrubbers and mechanical separators cannot be employed if adequate water is not available.
  • It is also very efficient for high dust loaded gas
  • It endows with ease of operation or function
  • The dust is accumulated in dry form and can be effectively removed wet or dry

There are numerous companies that provide spares for electrostatic precipitator ensuring they use best quality, licensed solution guaranteeing reliability and credibility. Their qualified engineer diagnoses the areas where replacement of electrostatic precipitator parts is needed, whether retrofitting and renovation services is required or not.

Electrostatic precipitator spares is cost effective in the long term. It is quite costly in the first purchase. However, in the long run, you will be benefitted as you don’t have to purchase replacement filters. Replacement filters can be quite problematic to replace. It is very crucial to note that ion charged plates has to be cleaned on a regular basis for highest and maximum performance. Hepa filters thrust air by fine filter. The design needs a profound responsibility for fan to push the air. ESP have almost no wind resistance and don’t need the pushing control of other models.
