Description

Waste gas treatment box

Technical Field

The utility model relates to an exhaust-gas treatment technical field, specifically speaking relates to an exhaust-gas treatment case.

Background

In the production process of industries such as petroleum, pharmacy, paint, printing and coating, high-concentration organic waste gas can be generated, the waste gas can stay in the atmosphere for a long time and can also be diffused and drifted to a far place to cause serious pollution to the environment, and the waste gas can directly cause great harm to the health of human bodies after being inhaled by the human bodies, so the organic waste gas is required to be treated to be purified and then discharged. At present, most of the treatment methods for organic waste gas are condensation method, adsorption method, catalytic oxidation method, liquid absorption method, biological method, plasma decomposition method, etc. because the components of organic waste gas are complex, the treatment method combining multiple treatment methods is generally adopted to treat organic waste gas. At present, the combination formula clean system that condensation method, liquid absorption method and adsorption method combined together is adopted to organic waste gas treatment method more, but current air inlet is direct ventilates in the box inwards, and gas gets into behind the box relatively concentrated, and the local adsorbing material that waste gas is concentrated is absorbent impurity many, leads to adsorbent life low, simultaneously, influences exhaust-gas treatment's efficiency and treatment quality.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a waste gas treatment case improves exhaust purification efficiency and purification quality.

The utility model discloses a technical scheme that exhaust-gas treatment case adopted is:

the utility model provides a waste gas treatment case, includes inclosed box, the both ends at box top are equipped with air intake and air outlet respectively, air intake connection has the intake pipe, the box middle part is equipped with the adsorbed layer, the box top is equipped with the shower head, the intake pipe includes main intake pipe and connects in a plurality of gas distributors of main intake pipe, the even tiling of gas distributor is in the adsorbed layer below, the venthole has evenly been seted up to the gas distributor on the outer wall.

Preferably, the diameter of the connecting end of the gas distribution pipe and the main gas inlet pipe is large, the diameter of the other end of the gas distribution pipe is small, and the gas distribution pipe is reduced in stages.

As a preferred scheme, a water tank is fixed on the side edge of the box body, the spray header is connected with the water tank through a water pipe, a collecting plate is arranged at the bottom of the box body and connected with a plurality of collecting pipes which are uniformly arranged, the collecting pipes are communicated with the water tank, and a water purifying device is arranged between the collecting pipes and the water tank.

Preferably, a demister is arranged at the air outlet.

Preferably, the adsorption layer is made of ceramsite and volcanic rock.

Preferably, the inner wall of the box body is coated with a corrosion-resistant material layer.

As a preferred scheme, a plurality of filling openings are formed in the top of the box body.

The utility model discloses a waste gas treatment case's beneficial effect is: waste gas gets into from the air intake, enters into the box through main intake pipe in, carries in to the box through a plurality of gas distribution pipes that evenly tile, and the even venthole of rethread gas distribution pipe makes gaseous bottom evenly distributed at the adsorbed layer, makes each position of adsorbed layer all have gaseous seeing through, improves purification efficiency and purification quality, can improve the life of adsorbed layer simultaneously. The gas passing through the adsorption layer falls to the fixed impurities carried by the gas through the water flow of the spray header, and the treated gas is discharged through the air outlet.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1-3, an exhaust treatment box includes a closed box body 10, an air inlet 11 and an air outlet 12 are respectively disposed at two ends of the top of the box body 10, the air inlet 11 is connected with an air inlet pipe, an adsorption layer 40 is disposed in the middle of the box body 10, the adsorption layer 40 is made of ceramsite and volcanic rock and can effectively adsorb odor sources such as ammonia gas and hydrogen sulfide, a shower head 33 is disposed at the top of the box body 10, the air inlet pipe includes a main air inlet pipe 21 and a plurality of gas distribution pipes 22 connected to the main air inlet pipe 21, the gas distribution pipes 22 are uniformly tiled below the adsorption layer 40, and the gas distribution pipes 22 are uniformly provided with air outlets 23 on.

The diameter of the connecting end of the gas distributing pipe 22 and the main gas inlet pipe 21 is large, the diameter of the other end of the gas distributing pipe is small, and the gas distributing pipe is reduced in stages, so that the flow speed of gas is kept relatively stable.

The box 10 side is fixed with water tank 30, and shower head 33 leads to pipe connection water tank 30, and the box 10 bottom is equipped with collecting plate 31, and collecting plate 31 is connected with a plurality of align to grid's collecting pipe 32, and collecting pipe 32 and water tank 30 intercommunication are equipped with water purification installation between collecting pipe 32 and the water tank 30, make overall structure more exquisite to can carry out cyclic utilization with the shower water.
