It can be used in chemical plants to remove oil mists and acid mists.It is installed in steam plants to remove the dust from impure gases.Here, we have mentioned some of the most important applications of electrostatic precipitators: They are only suitable for dry and wet pollutants.Īpplications of Electrostatic PrecipitatorsĪn electrostatic precipitator is used in the industries for various applications. The electrostatic precipitators cannot be used to remove gaseous pollutants.The device requires a very large space to operate properly.The electrostatic precipitators have a very high capital cost which makes it unsuitable for the small-scale industries.The disadvantages of electrostatic precipitator are The electrostatic precipitators have low operating costs and they are quite economically feasible in the long run.The dry precipitators collect the dry pollutants whereas the wet precipitators collect the wet pollutants. They are capable of collecting both dry as well as wet pollutants.The electrostatic precipitators have excellent efficiency and they can be used to remove 99% of the dust particles from the impure air. The advantages of electrostatic precipitator are The collectors are sprayed with water and the particles are collected from the sludge. The particles are given an electric charge as they pass through the corona. They are used in various industries where the chances of an explosion are quite high. Wet electrostatic precipitators are meant to remove wet particles like resin, oil, paint, tar, etc. The dust particulars which are removed from the stream of air are collected in a hopper and from there, they are extracted out. They are then made to flow through the electrodes. The particles are ionized and then they become electrically charged. The dust particles are collected from a stream of air. This type of precipitator collect the pollutants in a dry state and hence they are called dry electrostatic precipitators. Here, we have mentioned the different types of electrostatic precipitators: Dry Electrostatic Precipitator This helps to remove the dust particles from the gas stream.ĭifferent types of Electrostatic Precipitator A negative charge of thousands of volts is applied between the plates and the wires. The stream of gases is made to flow horizontally through the stack of plates and between the rows of vertical wires. The distance between the plates depending on the particular application. The plates have a separation of fewer than 0.5 inches to about 7 inches (about between them. Construction and Working of an Electrostatic PrecipitatorĪn electrostatic precipitator basically consists of a stack of flat vertical metal plates and a row of thin vertical wires. They are also capable of handling large volumes of gas at different temperatures. Some precipitators can also remove particles of 0.01 micron. They can help reduce particle pollution by removing particles whose sizes are nearly 1 micron (0.00004 inches) in diameter. They are used in the cleaning of flue gases. The Process Involved in Electrostatic PrecipitatorĮlectrostatic precipitators are extremely important tools from the industrial point of view. It is also used effectively in fossil-fuel power-generating stations. Today, it is used to control air pollution by removing particles from different gases. The electrostatic precipitators were initially used for various industrial processes. The precipitator is capable of applying energy to the particulate matter without hampering the flow of gases. It takes the help of electric charges in order to remove dust particles. What is an Electrostatic Precipitator?Īn electrostatic precipitator is a device that is capable of removing undesirable particles from air or any other gases. So, in order to get rid of such fine particulate matter, a highly advanced device called the electrostatic precipitator is used. They cannot be removed by simple filters or chimneys. Fine elements having a size of fewer than 2.5 microns and these are difficult to remove. Otherwise, they may pose a serious threat to the environment and also cause various health hazards like lung infection and bronchitis. Such type of waste will have to be removed before the gases are released into the environment. One such type of waste is particulate matter. There are a lot of industries that generate various waste particles while carrying out various manufacturing processes.
