Preferably, the inclined plane bottom plate is hourglass hopper-shaped, and forms a backward flow district in the central lowest department of inclined plane bottom plate, the bleeder vent set up on the inclined plane bottom plate outside the backward flow district, the buck back flow pipe is connected in the backward flow district.

Compared with the prior art, the beneficial effects are: the utility model discloses a handle a small amount of simple and easy device that contains acid gas industrial waste gas, its contact layer is from up being the inclined plane bottom plate that is covered with intensive bleeder vent from down in proper order, the gauze, the sponge layer, the inclined plane bottom plate plays fixed supporting role, the gauze, the sponge layer is because of its compliance and moist flagging nature, after the alkali lye humidification, make the industrial waste gas that contains acid gas can more fully contact with alkali lye and take place neutralization reaction, thereby reach the purpose that gets rid of waste gas and eliminate the peculiar smell, when industrial waste gas takes place the scale deposit blocking phenomenon after long time with alkali lye reaction time, can take out sponge layer and gauze easily and wash or change, alkali lye after the reaction can flow to the backward flow district along the inclined plane bottom plate, and flow back to the alkali cask through the alkali lye back flow, the alkali cask is equipped with small-size elevator pump, its export receives the water pipe crowd on the gas reactor after the reposition of redundant, a simple and easy device simple structure, it is with low costs that is used for the humidification of sponge layer and gauze to add alkali, makes sponge layer and gauze contain alkali lye all the time, is favorable to absorbing waste gas uninterruptedly, also makes whole device formation circulation, should handle a small amount of acid gas industrial waste gas that contains, and daily maintenance is convenient, and life is of a specified duration, has the feature of environmental protection.

Because certain moisture exists in the waste gas, after the waste gas enters the gas reactor, water vapor can drop in the gas reactor under the action of the inclined bottom plate, and finally can be discharged through the waste water outlet pipe and subjected to centralized treatment.
