Two different technical routes of industrial electrostatic precipitator

The test results show that the smoke and dust emission of industrial electrostatic precipitator can reach 10 mg/m or even 5 mg/m. The dust collection performance has nothing to do with the dust characteristics. It is suitable for the treatment of wet flue gas, especially for the treatment of dust-containing flue gas after wet desulfurization in power plants and steel plants.

Industrial electrostatic precipitator (ESP) is a kind of secondary dedusting equipment added after primary deduster and wet desulfurization. It can be divided into two types from the technical route. One is used to control the smoke and dust of coal-fired power plant, the other is a dedusting technology which comes from the chemical field and is used to control acid droplets in the exhaust gas. The obvious difference between the latter and the former is that the anode plate is made of metal, and the latter is made of non-metallic material, and the condensate droplets on the anode plate can slide reliably under dead weight without spraying water.

Industrial electrostatic precipitator (ESP) charges the dust by high voltage corona discharge, and the charged dust reaches the dust collecting plate/tube under the action of electric field force. Among them, dry ESP mainly deals with dry gas with very low water content, wet ESP mainly deals with wet gas with high water content and even saturation.

Compared with traditional dust removal equipment, industrial electrostatic precipitator has high dust removal efficiency, low pressure loss, simple operation, low energy consumption, no moving parts, no secondary dust, low maintenance costs, short production shutdown period, can work below the dew point temperature of flue gas, and can be combined with other flue gas treatment equipment because of its compact structure. The design forms are diversified.
