Description

Technical Field

[0001] The utility model belongs to the technical field of soil treatment, and particularly relates to a tail gas disposal device for soil treatment. Background Art

[0002] Organic pollutants enter the soil through leakage, penetration, etc., resulting in environmental pollution. These organic substances may be toxic, carcinogenic or persistent, posing a threat to the ecosystem and human health. The treatment of contaminated mud is an important topic in the environmental protection field, directly affecting water bodies, soil and the surrounding ecological environment.

[0003] Currently, the main methods for soil pollution remediation are physical, chemical and biological remediation technologies. However, these traditional remediation methods have the following main problems:

[0004] First, low efficiency: Traditional methods usually require a long time to significantly reduce the concentration of soil pollutants, and it is difficult to meet the urgent needs in practical applications.

[0005] Second, high cost: Many remediation methods require expensive equipment and reagents, and the overall remediation cost is relatively high, restricting large-scale applications.

[0006] Third, secondary pollution: Some methods may produce secondary pollution during the remediation process, such as chemical reagent residues or unqualified discharge of treatment waste liquid, further polluting the environment.

[0007] Among the existing soil pollution remediation methods, there is a lack of a process for treating the tail gas after soil treatment. If the waste gas after soil treatment is directly discharged, it will cause environmental pollution, and the tail gas must be treated before discharge. Summary of the Utility Model

[0008] In order to solve the above problems existing in the prior art, the purpose of the utility model is to provide a tail gas disposal device for soil treatment.

[0009] The technical solution adopted by the utility model is as follows:

[0010] A tail gas disposal device for soil treatment includes a tail gas treatment tank body. Inside the tail gas treatment tank body, there are several layers of contactors. The several layers of contactors divide the interior of the tail gas treatment tank body into several waste gas reaction chambers. The waste gas reaction chambers are filled with water. The surfaces of the contactors are coated with photocatalytic materials and contact catalytic materials. The bottom of the tail gas treatment tank body is connected with an exhaust gas inlet pipe.

[0011] The surfaces of the contactors of the utility model are coated with photocatalytic materials and contact catalytic materials. After the waste gas enters the tail gas treatment tank body through the exhaust gas inlet pipe, it comes into full contact with the photocatalytic materials and contact catalytic materials, so that the tail gas undergoes a full catalytic reaction, and the treated tail gas meets the emission standards.

[0012] As a preferred embodiment of the present utility model, one end of the exhaust gas discharge pipe away from the tail gas treatment tank body is connected with an exhaust gas discharge pipe for sending in exhaust gas. The exhaust gas generated after pyrolysis treatment of the soil is discharged into the exhaust gas discharge pipe and then sent into the tail gas treatment tank body through the exhaust gas discharge pipe. A section of the exhaust gas discharge pipe connected to the exhaust gas discharge pipe is a reduced-diameter section, so that the liquid in the tail gas treatment tank body cannot flow back.

[0013] As a preferred embodiment of the present utility model, the bottom of the exhaust gas discharge pipe is connected with an exhaust gas condensate collector, and a pressurizing device is arranged in the exhaust gas condensate collector.

[0014] As a preferred embodiment of the present utility model, a liquid discharge pipe is connected to the exhaust gas condensate collector. The condensate in the exhaust gas is sent to a liquid treatment device through the liquid discharge pipe for treatment.

[0015] As a preferred embodiment of the present utility model, a microbubble pipe is connected to the tail gas treatment tank body. The microbubble pipe sends microbubble liquid into the tail gas treatment tank body, and the microbubbles react with the photocatalytic material and the contact catalytic material on the surface of the contactor.

[0016] As a preferred embodiment of the present utility model, a number of microbubble aeration heads are arranged in the tail gas treatment tank body, and the microbubble aeration heads are communicated with the microbubble pipe. The number of microbubble aeration heads can eject the microbubble liquid from different positions, so that the microbubble liquid is more evenly distributed in the tail gas treatment tank body.

[0017] As a preferred embodiment of the present utility model, a number of microbubble aeration heads are annularly distributed in the tail gas treatment tank body.

[0018] As a preferred embodiment of the present utility model, a number of photocatalytic lamp posts are arranged in the tail gas treatment tank body, and the photocatalytic lamp posts penetrate through a number of contactors. The photocatalytic lamp posts can promote the catalytic reaction on the contactor.

[0019] As a preferred embodiment of the present utility model, a tail gas discharge port is arranged at the top of the tail gas treatment tank body. The treated gas is discharged from the tail gas discharge port.

[0020] As a preferred embodiment of the present utility model, the bottom of the tail gas treatment tank body is conical, and the exhaust gas discharge pipe is connected to the conical bottom of the tail gas treatment tank body.

[0021] The beneficial effects of the present utility model are as follows:

[0022] The surface of the contactor of the present utility model is coated with a photocatalytic material and a contact catalytic material. After the exhaust gas enters the tail gas treatment tank body through the exhaust gas discharge pipe, it comes into full contact with the photocatalytic material and the contact catalytic material, so that the tail gas undergoes a full catalytic reaction, and the treated tail gas meets the emission standards.
