TECHNICAL FIELD

[0001] The utility model relates to environmental protection technical field especially is a kind of waste gas treatment device for solid waste incineration. BACKGROUND

[0002] Many solid wastes (mainly refer to household garbage) contain potential energy, which can be recycled by incineration, but due to the extremely complex composition of these fixed wastes and the presence of various pollutants such as heavy metals, waste plastics, waste wood, etc., many chemical reactions will occur during incineration, and the flue gas produced contains flue gas pollutants harmful to the human body and the environment in addition to excess air and carbon dioxide. According to the chemical, physical properties of these pollutants and their harm to the human body and the environment. Therefore, the present application discloses a waste gas treatment device for solid waste incineration. SUMMARY

[0003] The utility model aims at present problem and provides a waste gas treatment device for solid waste incineration.

[0004] The utility model is realized through the following technical schemes: a waste gas treatment device for solid waste incineration, comprising a treatment tank, an upper cavity, a middle cavity and a lower cavity are arranged in the treatment tank, a plurality of pipe bodies are uniformly arranged in the middle cavity, the two ends of the pipe body are respectively connected with the top plate and the bottom plate, the pipe body communicates with the upper cavity and the lower cavity, a baffle is arranged obliquely in the lower cavity, the baffle is aligned with the air inlet pipe, the air inlet pipe penetrates the side wall of the treatment tank, an air outlet pipe is arranged penetratingly on the side wall of the upper cavity, the air outlet pipe is connected to the water tank, a bend pipe is arranged in the water tank, and the bend pipe communicates with the air outlet pipe.

[0005] As a further improvement of the above-mentioned scheme, the lower cavity is arranged in the inner shell, and a sandwich layer is arranged between the inner shell and the lower side wall of the treatment tank. By arranging a sandwich layer outside the lower cavity, the waste gas entering the lower cavity is isolated by the sandwich layer, preventing the side wall of the treatment tank from being too hot and scalding the operator.

[0006] As a further improvement of the above-mentioned scheme, an observation tube is arranged penetratingly on the side wall of the treatment tank, the two ends of the observation tube communicate with the upper part and the lower part of the middle cavity respectively, and a water injection pipe and a drain pipe are arranged on the side wall of the middle cavity; the liquid condition in the middle cavity can be easily observed through the observation tube, so that the cooling liquid in the middle cavity can be added in time, or the cooling liquid in the middle cavity after absorbing heat can be replaced by circulating through the water injection pipe and the drain pipe.

[0007] As a further improvement of the above-mentioned scheme, an inclined port is arranged at the inner end of the air inlet pipe, the inclined port is parallel to the baffle plane, ensuring that large particles in the waste gas are blocked and fall onto the bottom of the lower cavity.

[0008] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. By using a baffle to block the exhaust gas entering the lower cavity, large particles in the exhaust gas are blocked and fall to the bottom of the lower cavity. The exhaust gas enters the pipe body from the lower cavity, and the heat in the exhaust gas is absorbed by the water in the middle cavity, which cools the exhaust gas and allows it to enter the upper cavity. Then, it enters the bend pipe through the exhaust pipe. The water in the water tank settles the micro particles in the exhaust gas and neutralizes harmful gases. It can effectively filter particles and harmful gases in the exhaust gas, greatly reducing air pollution and harm to the human body. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figs. 1 to 3 As shown, a waste gas treatment device for solid waste incineration includes a treatment tank 1. The treatment tank 1 is provided with an upper cavity 12, a middle cavity, and a lower cavity 3. Several pipes 7 are evenly distributed in the middle cavity. The two ends of the pipes 7 are respectively connected to a top plate 8 and a bottom plate 6. The pipes 7 connect the upper cavity 12 and the lower cavity 3. A baffle 4 is inclinedly arranged in the lower cavity 3. The baffle 4 is aligned with the air inlet pipe 5. The air inlet pipe 5 passes through the side wall of the treatment tank 1. An air outlet pipe 13 is provided through the side wall of the upper cavity 12. The air outlet pipe 13 passes through and connects to a water tank 14. A bend pipe 15 is provided in the water tank 14. The bend pipe 15 connects to the air outlet pipe 13.

[0014] As a further improvement to the above solution, the lower cavity 3 is set inside the inner shell 2, and an interlayer is set between the inner shell 2 and the lower side wall of the treatment tank 1; by setting an interlayer outside the lower cavity 3, the exhaust gas entering the lower cavity 3 is isolated by the interlayer, so as to avoid the side wall of the treatment tank 1 being too hot and burning the operators.

[0015] As a further improvement to the above solution, an observation pipe 9 is provided through the side wall of the treatment tank 1. The two ends of the observation pipe 9 are respectively connected to the upper and lower parts of the middle cavity, and a water injection pipe 10 and a drain pipe 11 are provided on the side wall of the middle cavity. The liquid condition in the middle cavity can be easily observed through the observation pipe 9, so as to add coolant to the middle cavity in a timely manner, or to circulate and replace the coolant in the middle cavity after absorbing heat through the water injection pipe 10 and the drain pipe 11.

[0016] As further improvement of the above-mentioned scheme, the inner end of the air inlet pipe 5 is provided with an inclined port, which is parallel to the plane of the baffle 4, so as to ensure that the large particles in the exhaust gas are blocked and fall on the bottom of the lower cavity 3.

[0017] The working principle of the exhaust gas treatment device for solid waste incineration is as follows: the exhaust gas enters the lower cavity 3 from the air inlet pipe 5, is blocked by the baffle 4, so that the large particles in the exhaust gas are blocked and fall on the bottom of the lower cavity 3, and then the exhaust gas enters the pipe body 7 from the lower cavity 3, the heat in the exhaust gas is absorbed by the water in the middle cavity, so that the exhaust gas is cooled and enters the upper cavity 12, then enters the elbow pipe 15 through the air outlet pipe 13, and the water in the water tank 14 is used to settle the fine particles in the exhaust gas and neutralize the harmful gas, so that the particles and harmful gas in the exhaust gas can be effectively filtered, and finally the exhaust gas can be discharged in compliance with the standard, which can greatly reduce the pollution to the air and the harm to the human body.
