Description

A waste gas treatment conveying device for environmental protection equipment

technical field

The invention relates to the field of environmental protection equipment, and more specifically relates to a waste gas treatment and conveying device for environmental protection equipment.

Background technique

The working principle of the existing photo-oxygen integrated machine exhaust gas treatment equipment: 1. Fresh air enters the generating cabinet through coarse filtration; 2. The incoming fresh air is strongly sent into the barn body through the blower; 3. The positive pressure of the oil sent into the room body The air is shunted under the action of the static pressure chamber, and evenly enters the painting studio on the lower floor after being filtered; 4. The exhaust gas generated during the painting process passes through the ground filter layer under the steel grille of the baking room platform and then discharges to the light. Oxygen waste gas treatment cabinet; 5. When the waste gas passes through the photo-oxygen waste gas treatment cabinet, it passes through medium-efficiency filter cotton, bag filter cotton, and UV lamp tube; 6. After photolysis of photocatalyst, it is harmless after being neutralized and decomposed by ozone Discharge; 7. The harmless gas after the treatment is exhausted by the exhaust fan to the outdoor atmosphere through the exhaust pipe.

Existing photo-oxygen integrated waste gas treatment equipment lacks the pretreatment of the gas that cannot enter when the waste gas enters the generating cabinet. For example, the waste gas containing chloroform, carbon tetrachloride, hexachlorobenzene, etc. The gas that enters into the generating cabinet is easy to cause damage to the generating cabinet. In view of this, we propose a waste gas treatment and conveying device for environmental protection equipment.
