Operation principle:

The present invention utilizes foam that waste gas is processed, and can effectively strengthen the absorption to small dust granules, and has reduced industrial processing waste gas water consumption used, adds simultaneously suitable surfactant and improve the SO in industrial waste gas in foam 2, H 2The absorption of the pernicious gases such as S utilizes dust concentration tester to carry out Real Time Monitoring to the dust in equipment, and inductor in time increases and decreases the injection rate of foam automatically, has improved the treatment effeciency of industrial waste gas.

Compared with prior art, advantage of the present invention is:

The mode of the present invention by the foam gas washing solved the shortcomings such as existing waste gas treatment equipment is low to the treatment effeciency of small dust granules in industrial waste gas, water consumption is large, the suitable surfactant of interpolation has more and processes targetedly waste gas in foam, utilize dust concentration tester to carry out Real Time Monitoring to the dust in equipment, automatically inductor in time increases and decreases the injection rate of foam, has greatly improved the disposal ability of present device to industrial waste gas.
