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.

The Big Smoking Zone of the Country:

Industrial areas are the backbone of every country. So, before thinking  to stop industrialization, that is the most common thinking of masses, think pragmatic to reduce pollution without getting hazard the industry and their prosperity.

Lack of exposure to sunlight children get affected in rickety or various bone deficiency diseases as the smog in air of these areas block sunlight. A permanent smoke haze has already enveloped some areas of Delhi, Patna, Gwalior and Raipur.

According to the “smoke control laws in India” apart from banning tobacco smoking in public zone or creating an extra smoking zone in railway stations or airports, it is mandatory to install Electrostatic Precipitator in every industrial zone of this country.

A little talk about Electrostatic Precipitator.

Electrostatic Precipitators: Way to Kill Industrial Flue Gas

industrial air pollution

Okay, ‘electrostatic precipitator’ is way too technical. Let’s call these machines the scrubbers. They are inherently static-electricity filters, designed to steal dust, soot, ash, and grime from industrial smoke. It goes without asking that they contribute to the minimisation of air pollution. Yes, they are a technological marvel.

Want To Know How A Scrubber Works?

Comb your hair vigorously on a cold, dry day, You’ll notice that the strands cling on to the teeth of the comb. Well, that’s static electricity.

ESPAs the comb rubs against your tresses repeatedly, the electrons break free from them and settle on it instead. At this point of time, your hair is positively charged and the comb negatively. This explains the weird attraction.

Something of the like happens in a scrubber as well. Industrial smoke is actually an aerosol. It may look like gas, but the properties are different. That’s solid suspended in a gaseous medium. The suspended particles are unburned carbon.

The idea is to ‘rub’ the particles so that they receive an electrical charge. These when passes through a medium with the opposite charge, can be pulled out and removed.

Simple, right? Wrong.

There’s more.

Industrial smoke, aka flue gas, is forced through two electrodes inside a smokestack. The negative electrode imparts negative electrical charge to the suspended particles. The second electrode is the positive one and located up or beyond the negative electrode. They attract the charged particles.

Until this point, it is more or less similar to the hair strands attaching to the comb. However, the challenge is to get rid of the pulled particles from the electrode, which is also known as the collector plate.

It needs to be shaken from time to time so that the older particles are emptied and there’s room for newer particles. This can be done manually by brushing or, automatically using an automated shaker or rapper, after which, the particles are disposed of.

ESP at a industry

What Are The Typical Activities Of A Scrubber?

If we go by the above explanation of how a scrubber works, here are the six typical activities that take place inside it:

1. Ionisation – The particles are charged.
2. Migration – The particles are taken to the collector plate.
3. Collection – The particles are collected onto the collector plate.
4. Neutralisation – The particles are neutralised on the collector plate so that they fall.
5. Dislodging – The particles are dislodged onto a hopper.
6. Removal – The particles are carried from the hopper for disposal or recycling.

Which Particulate Properties Affect Electrostatic Precipitators?

Various electrostatic precipitators are designed for particles of various sizes, chemical compositions, and amounts. Here are the two most important aspects of suspended particles that normally affect these scrubbers:

• Electrical resistivity
• Particle size distribution

Other aspects include:

• Temperature of the flue gas
• Its moisture content
• Overall design of the machine
• Whether the rapper is manual or automated
• Whether single-stage or multi-stage scrubbing
• Whether the removed particles should be disposed of or recycled.
• Heterogeneity of the pollutants that the flue gas contains

So, now that you know the scrubber inside out and the loads of environmental benefits it brings, why not have it installed in your industrial plant as well? Like they say, let the machine take care of the machine while we enjoy a good life.

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.

Industrial emissions contribute a lot to this major problem of global warming, so installing ESP or Electrostatic Precipitator in  Chemical, cement industries and power plants can reduce the amount of air pollution substantially and can be of much help in the long run. Save Our Earth! Let it breathe!

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.

The Way Electronic Air Purifier Works

Let us look at how the electronic air channel, which is one of the four sorts of air channels, attempts to guarantee that air contaminants in a room are minimized.

Electrostatic-Precipitator-SparesThese sorts of room air cleaners vary as to the instruments by which they dispose of contaminants from the air. The three different sorts of air channels are the gas stage, mechanical, and half breed air channels. In mechanical air channels, the air is compelled to pass through an uncommon sort of screen and this will trap different sorts of aggravation particles and allergens before the air gets into the lungs of individuals. In the gas stage air channel, the undesirable contaminants and smells are caught utilizing a permeable, which is normally actuated carbon. The electronic air channel meets expectations by making electrostatic charges in the channel to draw in and trap allergens and different aggravations.

Electronic channels are regularly introduced with aerating and cooling frameworks to improve indoor air filtration in the different parts of the home. The contaminants and aggravations buzzing around are compelled to experience a pre-filter that capacities as a trap for a large portion of these undesirable particles. Those particles that have the capacity traverse the pre-filter are given an electric impulse. This type of residence air channels is given gatherer plates that draw in the electrically charged particles where they stay until the air cleaner is cleaned or Electrostatic Precipitator Spares are replaced.

The electronic air channel can be of two sorts: the charged media channel and the electrostatic precipitator. In the charged media channel, the dust and contaminants are caught in charged filaments. In the electrostatic precipitator, an arrangement of charged plates serves as the authorities. The electrostatic precipitator has better accumulation proficiency in light of the fact that it delivers around 20,000 volts to instigate a static electric charge in the dust particles and other undesirable poisons. This type is more appropriate and helpful and is commonly used all over to have pure air.

Now, if you are a renowned industrialist and in search of high quality ESPs, then there are multiple companies that are reputed for delivering supreme materials. So, just get charged up and order in bulk to serve your own purpose. The enterprises also provide effective transport facility to transfer the resources to the preferred destination.

The Easy Solution of Electrical Insulation with ESP Insulator

Electrical wiring is designed to withstand a certain measure of voltages yet the insulation ensures that the electricity is guided where it needs to. To keep up the honesty of an electric wire’s insulation, the strength of the insulating elements need to test all the time.

ESP-Insulators

Types of Insulation Tests
There are three tests that you can lead to test the uprightness of the insulation on a wire. The first one is carried out to focus the measure of voltage that an insulator can withstand before is degrades. It involves passing high voltage present between two points on a wire and you continue increasing the voltage until the insulation starts to give in. ESP Insulator helps to tests are used to figure out if a certain link can withstand a set measure of voltage for an obliged period. It involves applying a voltage for a specific measure of time and viewing the current that leaks through the link. You can dare to dream that there is no spillage and the link remains in place. This test is intended to figure the resistance of the insulation to high voltage electricity. There is an estimation included yet the best thing to be to use an Ohm meter.

Check the Electrical Streaming
You may be acquainted with the congruity test that successfully tests whether there is any electrical stream between two points. The desired results of such a test is to have current streaming, with a alumina insulator you are checking for good isolation, you don’t need the present to stream, you need it to stay in one region to test the trustworthiness of the insulation in that single territory. Insulator for ESP detects the slightest changes that happen in high voltage circuits. It is normally used in high voltage industrial applications and in spite of the fact that there are units that might be used to test your ordinary common insulation.

At the point when electrical insulation breaks down it may cause electrical failure and accidents that cause harm and fatalities consistently.
