Embodiment Construction
[0016] The whole process from the dirty gas inlet 2 to the clean gas outlet 3 is a purification channel 15, on which a dirty gas filtering channel 7 is arranged, and the dirty gas filtering channel 7 is connected in series with the cleaning channel 15 to form a section of the cleaning channel 15; The dirty gas filtering channel 7 is always filled with water 5, and the dirty gas filtering channel 7 is provided with a filter unit 9 composed of a filter unit 8. The inner walls of the dirty gas filter channel 7 match, forcing the dirty gas 12 to pass through the small holes in the filter device 9 and be forcibly cut into tiny bubbles and washed repeatedly by the water 5. The dirty gas 12 passes through the dirty gas filter channel 7 to the clean gas The outlet 3 advances and is finally sucked out from the clean gas outlet 3; at the clean gas outlet 3, an exhaust fan 13 is connected to form a negative pressure in the space of the purification channel 15 at the front end of the clean...

The invention belongs to the field of gas purification and particularly relates to a suction type water bath waste gas purifying method. The suction type water bath waste gas purifying method is applicable to any places requiring waste gas purification such as indoor air purification as well as closed space such as automobile cab air purification, kitchen ventilator fume purification, industrial and domestic boiler smoke purification, and garbage incinerator / steel furnace / power plant coal-fired furnace purification. The entire passage from a waste water inlet to a clean gas outlet is a purification channel, a waste gas filtering channel is connected in series into the purification channel, filled with water and provided with a filtering device composed of filtering units; waste gas passively passes through a small hole inside the filtering device and is forcibly cut into tiny bubbles, then repeatedly bathed and lastly sucked out via the clean gas outlet; the clean gas outlet is connected in series with an exhaust fan which sucks out and exhausts clear gas via the clear gas outlet. The suction type water bath waste gas purifying method achieve zero-emission purification effects andmeanwhile is simple and efficient.
Description
[0001] Field [0002] The invention belongs to the field of gas purification, in particular to a suction-type water bath dirty gas purification method. It is suitable for any place that needs to purify dirty gas, such as indoor air purification, air purification in closed spaces such as motor vehicle cabs, range hood fume purification, industrial boilers, civil boiler fume purification, waste incinerator fume purification, coking ovens and steelmaking furnaces Smoke and dust purification, coal-fired furnace smoke and dust purification in power plants, factory dust purification, laboratory air and secondary purification of motor vehicle exhaust. Background technique [0003] At present, the conventional dirty gas purification method is mainly realized by spraying air with water or high-voltage electrostatic adsorption, but the purification effect of this method is not good and the structure is complicated. Therefore, simple and efficient air purification technology is very imp...
