Electro Static Precipitator (ESP)

Soil & Enviro Industries offers an Electro Static Precipitator (ESP), the most efficient equipment in the field of industrial air pollution control. It has wide range of applications such as in the field of power, cement, steel, sponge iron, etc. The efficiency of operation may reach 99.9% in ideal conditions. The ESP consists of high voltage (HT) emitters, generally called discharge electrodes, and adjacent particle collection surfaces generally called collecting electrodes. In its simplest form an electro-precipitator consists of a single wire at very high electrical potential inside a single earthed tube. With increase of HT voltage, at negative potential, electrical potential occur across the space gap from the wire towards the earthed (positive) tube surface. How does it work It is electro mechanical, high voltage equipment mainly consisting of two sets of electrodes held in rows and separated by a particular electrical gap/distance. One set of electrodes (discharge electrode) is fed with high voltage DC (max up to 110 kV) generated through transformer rectifier set, to set free “Corona” (free flow of electron). The other set of electrodes (collecting electrode) is earth connected. When dust laden gas passes through the field, due to the corona effect, the gas gets “ionised” and negatively charged. It forms an electron storm and drags the dust along with it towards the earth plate (collecting plate) where it gets discharged, and the clean flue gas passes out through the stack. Now through rapping mechanism the dust gets dislodged into the hopper of the ESP and subsequently the dust is taken out through dust conveying systems. The ESP is designed in such a way, that it can work at any condition, considering on the predetermined facts.
