Compared with prior art, the beneficial effects of the present invention are:
Using deduster of the present invention, by the airflow-distribution board arranged in air inlet horn mouth when flue gas enters shell, can make
Flue gas is evenly dispersed, avoids dedusting cavity concentrated wear serious, efficiency of dust collection can be improved.When deduster water supply of the present invention, from
Inlet tank enters header, then enters the snakelike heat exchange tube in anode plate from header, increases changing between flue gas and anode plate
Fume afterheat utilization not only can be improved in heat, but also since dust particles there are the temperature difference, can be made in electric precipitation to flow to from high-temperature region
Low-temperature space promotes anode plate to gather dust, in addition, the surface temperature of the anode plate as dust collection plate can be reduced with cooling high temperature flue gas
Dust particles specific resistance, to effectively back corona phenomenon be inhibited to generate.It can effectively improve fume afterheat using the present invention to utilize,
Exhaust gas temperature in electric precipitator is reduced, so that flow of flue gas is slowed down, reduces reentrainment of dust, improves the dedusting effect of electric precipitator
Rate, the effectively save energy, energy conservation and environmental protection.
The present invention is used for the dedusting of Industrial Boiler flue gas, fume afterheat can be made full use of, not only improve electric precipitation
The efficiency of dust collection of device, and the effectively save energy, energy conservation and environmental protection.
