The organic waste gas purifying equipment overcomes the disadvantages of similar type equipment. The organic waste gas purifying equipment has reasonable length width ratio, and is additionally matched with a conic airflow distributor with holes. The conic airflow distributor with holes enables gas flow to be evenly distributed on a cross section. The organic waste gas purifying equipment solves the question that the periphery of a bed body and a charcoal layer can not be sealed together. The peripheral edges of front and rear net plates are additionally provided with fixing side frames for overcoming border effect. The charcoal layer is designed into an integral type fixing bed, and any steel is not arranged in the charcoal layer. The filling of the charcoal layer adopts longitudinal and transversal double displacing arrangement, which overcomes a leak short-circuit phenomenon.

Description

The cleaning equipment of organic exhaust gas

The utility model relates to a kind of cleaning equipment of organic exhaust gas.Be used for the improvement of industrial organic exhaust gas, be particularly useful for the improvement of organic exhaust gas under the big air quantity of low concentration.

The cleaning equipment of domestic organic exhaust gas of the same type is a filling material with the honeycomb block shaped activated carbon at present, and its charcoal layer adopts assembling (drawer) formula structure, but exists following major defect:

1, long (height H on the equipment air-flow front) wide (the width b in equipment air-flow front) of bed influences air-flow and evenly distributes on the bed cross section, thereby reduced the equipment effective rate of utilization than excessive (being about 2).

2, because bed is assembling (drawer) formula structure, form by many movably drawer type lectulum layers in the bed, just on drawer frames and its moving track, formed crack inevitably, caused serious boundary effect, thereby reduced the purifying rate of equipment;

3, since in the bed many little drawer frames adopt the weldering of stuffiness iron straps to make, retaining has removed the front portion passage, this has not only increased bed resistance, face and also reduced the effective rate of utilization of sorbing material in the bed;

4, because little drawer frames and its track that is complementary in the bed are made by steel, not only increased the weight and the processing charges of adsorbent bed, and relatively reduced the gas defence ability.

The purpose of this utility model provides a kind of cleaning equipment of improved organic exhaust gas, can overcome crack short circuit phenomenon and serious boundary effect in the bed; Improve air-flow distribution in the bed; Improve the effective filtration area of bed.

The purpose of this utility model is achieved in that the cleaning equipment that a kind of organic exhaust gas promptly is provided, and it comprises airscoop shroud, adsorbent bed body and air leaving cover, the two ends of adsorbent bed body respectively with airscoop shroud and giving vent to anger.Cover connects with flange screw.A conical air-flow distributor that has several uniform small sircle holes is arranged in airscoop shroud, between airscoop shroud and circular cone air-flow distributor, be welded in the outside of the inboard and circular cone air-flow distributor of airscoop shroud respectively in two ends separately with some uniform poles, the honeycomb block shaped activated carbon filling layer of arranging by the two dislocation of vertical, horizontal (claiming charcoal layer and bed again) is housed in the adsorbent bed body, two ends at the charcoal layer are fixed with the front and back web plate respectively promptly, web plate comprises frame and wire netting, and frame can be used angle steel.Wire netting between placed in the middle and one side of frame are fixedly connected, and another periphery of frame is fixed on the body with screw.

The cleaning equipment of the organic exhaust gas that the utility model proposes has rational length-width ratio, and generally being controlled at 1～1.3 is ab=1～1.3; Other increases and joins a conical air-flow distributor with some holes (can uniform 12 apertures at the conical surface), and air-flow is evenly distributed on equipment; Equipment sectional area A1=H * b and conical bottom area A 2=Π O ²/ 4 ratio is 5～6, i.e. A1/A2=5～6.To overcome serious boundary effect and bed crack phenomenon, increase the flatness and the rigidity of bed body, charcoal layer contact-making surface is close on the body periphery.If little crack is arranged with fillings such as other material such as asbestos cords, the charcoal layer adopts the two dislocation of vertical and horizontal to arrange when filling charcoal piece in addition, to overcome the crack short circuit phenomenon that forms in the charcoal layer, if there is crack to adopt little charcoal piece to fill up, to improve the gas defence performance of equipment; Filling layer of the present utility model is an overall fixed formula bed, no any steel in the bed.

In sum, the cleaning equipment of the organic exhaust gas that the utility model proposes can solve the distribution of air flow problem of non-uniform, overcome serious boundary effect and bed crack short circuit phenomenon, the filling layer is the overall fixed layer, wherein there are not any steel, improved effective area, the overall performance level of equipment is increased, at first increased substantially the gas defence ability, more than 30%, reduce concentration of emission according to height drug abuse total capacity, alleviated weight, reduce cost, had tangible economic benefit and social benefit.
