Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an exhaust gas treatment device in this embodiment includes an outer tank 1, the top of the outer tank 1 is in a shape of a truncated cone, a partition plate 2 is fixed at the top of the maximum diameter of the inner side of the outer tank 1, the partition plate 2 is in a ring shape, an inner tank 3 is fixed at the inner side of the partition plate 2, a top opening of the inner side of the outer tank 1 is fixedly connected with the inner tank 3, the bottom of the inner tank 3 is in a shape of a truncated cone, an exhaust pipe 4 is connected at the top of the inner tank 3, a cavity is formed between the inner tank 3, the partition plate 2 and the outer tank 1, an external pipe 10 extending to the cavity is fixed at the outer side of the outer tank 1, a plurality of air guide pipes 9 extending to the inner tank 3 are fixed at the bottom of the partition plate 2, air guide ports of the air guide pipes 9 are immersed in liquid in the inner tank 3, a filter layer 8 is fixed at the inner side of the inner tank 3, a drain pipe 11 and a water inlet pipe 5 extending to the outer side of the outer tank 1 are connected at the outer side of the inner tank 3, and a filter screen is arranged inside the drain pipe 11.

In this structure, take over outside with the leading-in cavity of waste gas in, waste gas then through a plurality of air duct evenly dispersed's leading-in inner tank with the liquid neutralization, can play the effect of aeration simultaneously to can improve the neutralization effect of liquid and waste gas, unnecessary waste gas can discharge after filtering again through the filter layer, thereby can effectively improve filterable effect.

In order to clean the filter layer, a water guide pipe 6 communicated with an external water source is fixed on the inner side of the inner tank 3, the water guide pipe 6 is positioned above the filter layer 8, and a plurality of spray heads 7 are installed at the bottom of the water guide pipe 6. The external water source is introduced through the water guide pipe, and the impact of the water source is sprayed out through the spray head, so that impurities attached to the bottom of the filter layer can be cleaned, and meanwhile, the residual waste gas can be neutralized, so that the effect of filtering the waste gas is improved in an auxiliary manner.

In order to achieve the effect of solid-liquid separation, the bottom of the outer tank 1 is provided with a cylinder 13, the top of the cylinder 13 is fixed with a top block 14, the top block 14 is conical, the bottom of the inner tank 3 is sealed by the top block 14, and the outer side of the outer tank 1 is provided with a slag discharge port 12. When water and waste gas neutralization form waste water, then in the inside import chemical reagent through the inlet tube to can solidify the impurity in the waste water, consequently can discharge water through the drain pipe, then drive the kicking block through the cylinder and remove the seal to the inner tank, solidification impurity can concentrate in the outer jar, thereby be convenient for arrange the cinder notch and collect the processing to impurity.

The working principle of the embodiment is as follows:

the water source is led into the inner tank through the water inlet pipe until the air guide pipe is immersed, then the production waste gas is led into the cavity through the outer connecting pipe, the waste gas is evenly dispersed into the inner tank through a plurality of air guide pipes to be neutralized with water, meanwhile, a proper amount of chemical reagent is injected through the water inlet pipe, and meanwhile, the air guide of the air guide pipe is matched, so that the effect of aeration can be formed, the water source, the chemical reagent and the waste gas can be mixed, the waste gas can be neutralized, the waste water is coagulated, the rest waste gas can be filtered through the filter layer, when the residual waste gas rises, the water guide pipe is used for leading the external water source into, the waste gas can be sprayed through the spray head to neutralize the water source sprayed by the residual waste gas, the water source sprayed out can be used for cleaning the filter layer, the filter layer is prevented from being excessively long in service time, meanwhile, air can be discharged to the outside through the exhaust pipe, the filtering effect can be improved, the filter layer can be cleaned under the condition of not being dismantled, time and labor are saved, and the follow-up waste gas treatment is avoided.

When exhaust-gas treatment is finished, water in the inside waste water and impurity separation can be conducted out the water source through the drain pipe preferentially, then drive the kicking block through the cylinder and remove downwards, make kicking block and interior tank bottoms part, consequently the kicking block is the toper, and consequently inside solidification impurity can the landing collect to the bottom of outer jar, then is exporting impurity through the row's cinder notch and handling.

The entire workflow is completed and what is not described in detail in this specification is well known to those skilled in the art.
