All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] Refer to Figures 1-4 As shown in the figure, an embodiment provided by the present invention: An exhaust gas treatment device with a secondary treatment function includes a filter box 1. A detection box 4 is fixedly arranged on one side of the filter box 1. A water tank 2 is fixedly arranged in the middle of the upper end of the filter box 1. A circulation pump 19 is fixedly arranged inside the water tank 2. A multi-stage filter screen 6 is slidably arranged at one side inside the filter box 1. A purification box 15 is fixedly arranged at the other side inside the filter box 1. A zeolite molecular sieve 16 is movably arranged at one side inside the purification box 1. Activated carbon particles 17 are movably arranged at the other side inside the purification box 1. A gas detector 18 is fixedly arranged on one inner wall of the detection box 4. An air delivery pipe 13 is fixedly arranged at the rear of the detection box 4. An air pump 20 is fixedly arranged at the rear end of one inner wall inside the filter box 1.
[0032] The filter box 1 is conducive to filtering the exhaust gas. The detection box 4 is conducive to detecting whether the treated gas meets the emission standards. The gas detector 18 is conducive to detecting whether the gas meets the emission standards. The water tank 2 is conducive to the storage of water. An inlet is opened on one side of the water tank 2, which is conducive to the entry of water. The circulation pump 19 is conducive to transporting the water source in the device box 12 into the sprinkler head 10 for recycling. The multi-stage filter screen 6 filters a large amount of dust remaining in the exhaust gas to make it meet the emission standards. The zeolite molecular sieve 16 is conducive to cooperating with the activated carbon particles 17 to adsorb bacteria and strange smells in the exhaust gas, which is conducive to the filtration of the exhaust gas. The air delivery pipe 13 is conducive to the transportation of gas. Solenoid valves are arranged in the pipelines of the device. The air pump 20 is conducive to cooperating with the air delivery pipe 13 to achieve secondary filtration of the gas. By starting the air pump 20, the gas in the detection box 4 is transported to one side of the filter box 1 through the air delivery pipe 13 for secondary detection, which is fast and convenient.
[0033] There are circulating pipes 8 fixedly arranged at the front and rear ends of the water tank 2. At the lower end of one of the front ends of the two circulating pipes 8, a fixed pipe 9 is fixedly arranged. At the lower end of the fixed pipe 9, a plurality of spray heads 10 are fixedly arranged. In the middle position of the inner bottom surface of the filter box 1, a device box 12 is fixedly arranged. At the lower end of the device box 12, a drain pipe 14 is fixedly arranged. On the inner ground of one side of the filter box 1, a plurality of device boxes 7 are movably arranged. On both inner walls of the middle part of the filter box 1, waterproof membranes 11 are fixedly arranged. At the lower end position of one side of the filter box 1, an air inlet 3 is fixedly arranged. On the other side of the detection box 4, an air outlet 5 is fixedly arranged.
[0034] The circulating pump 19 is beneficial to transporting the water source in the device box 12 to the inside of the spray heads 10 through the circulating pipes 8 for recycling. The fixed pipe 9 is beneficial to transporting the water source to the spray heads 10. The spray heads 10 are beneficial to the full contact between the water source and the gas. By using the characteristic that some substances in the waste gas are easily soluble in water, the components of the waste gas directly contact with the water, and thus dissolve in the water to achieve the purpose of deodorization. The setting of the device box 12 is beneficial to the device of the water source. The setting of the drain pipe 14 is beneficial to the discharge of the water source after multiple uses. A solenoid valve is arranged inside the drain pipe 14 to facilitate the control of the discharge of the water source. The device box 7 is beneficial to the device of dust.

The waterproof membrane 11 is made of polytetrafluoroethylene microporous membrane material and has the characteristic of being breathable but not permeable to water.
[0035] Working principle: When this device is in use, the waste gas enters the filter box 1 through the air inlet 3. A large amount of dust remaining in the waste gas is filtered through the multi-stage filter net 6 to meet the emission standards. The filtered dust will fall into the device box 7. Then, the circulating pump 19 is started to transport the water source in the water tank 2 to the spray heads 10. By using the characteristic that some substances in the waste gas are easily soluble in water, the components of the waste gas directly contact with the water, and thus dissolve in the water to achieve the purpose of deodorization. The water source can also be replaced with a certain chemical agent to facilitate the chemical reaction with the waste gas. Then, the bacteria and strange smells in the waste gas are adsorbed through the cooperation of the zeolite molecular sieve 16 and the activated carbon particles 17, which is beneficial to the filtration of the waste gas. Finally, the gas enters the detection box 4, and the gas detector 18 detects whether it meets the standards. If it meets the standards, it is discharged from the air outlet 5. If it does not meet the standards, the air pump 20 is started, and the gas in the detection box 4 is transported to one side of the filter box 1 through the air delivery pipe 13 for secondary detection. It is fast, convenient, time-saving and easy to use.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
