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 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.
