Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1-8 As shown, this utility model discloses a waste gas collection and treatment device, comprising:

[0030] The housing 1 has a spray chamber 2 and a filter chamber 3 connected inside the housing 1. The spray chamber 2 has an air pipe interface 21 connected to the outside and an air extraction pipe (not shown).

[0031] The spray chamber 2 has several compartments 22, each compartment 22 is sealed and separated by partitions, and each compartment 22 is equipped with a spray pipe 24.

[0032] The filter chamber 3 has several filter cylinders 31 and exhaust vents 32. The filter cylinders 31 are matched with the spray pipes 24, and the exhaust vents 32 are located on the side wall of the filter chamber 3.

[0033] The top of the housing 1 is also provided with an exhaust module 4, and the bottom is provided with an exhaust fan (not shown). The exhaust module 4 is connected to the spray chamber 2.

[0034] In this invention, an exhaust pipe (not shown) is inserted into the air pipe interface 21. The exhaust pipe is aligned with the position to be cleaned. The exhaust gas enters the housing 1 through the suction airflow generated by the exhaust fan. The spray chamber 2 and the filter chamber 3 treat the exhaust gas and then discharge it to meet the emission requirements. In addition, the partition 22 allows different exhaust gases to be discharged into different partitions 22 for separate treatment, avoiding the mixing and pollution of impurities in the exhaust gas.

[0035] The bottom of the filter chamber 3 is provided with a drain outlet 33. The filtered liquid is discharged through the drain outlet 33.

[0036] In some embodiments of this invention, a partition is provided between the spray chamber 2 and the filter chamber 3. The partition is inclined to the horizontal plane, and a filter structure 5 is provided at the bottom of the partition. The filter structure 5 consists of a high-precision filter screen 51, filter cotton 52, and activated carbon 53. The inclined partition facilitates the discharge of liquid from the spray chamber 2. The liquid that has been treated for waste gas flows into the filter chamber 3 through the bottom filter structure 5 and is then discharged. The filter structure 5 also filters the liquid, preventing the discharge of pollutants.

[0037] In some embodiments of this invention, the horizontal height of the spray pipe 24 is greater than the horizontal height of the air pipe interface 21. This structure can quickly treat exhaust gas and prevent it from dispersing in the spray chamber 2.

[0038] In order to purify different exhaust gases at the same time, the size of the filter cartridge 31 corresponding to each compartment 22 is different, so as to meet the filtration and purification of different exhaust gases.

[0039] In addition, the filter cartridge 31 is provided with a high-precision filter screen, a primary barrier cotton 311, a primary activated carbon 312, a secondary barrier cotton 313, a secondary activated carbon 314, and a cartridge body 315 from the inside out. The bottom of the cartridge body 315 is also equipped with a waste bin cover 316 for collecting pollutants, and the waste bin cover 316 is detachably connected to the filter body. The multi-layer barrier cotton and activated carbon configuration allows for better filtration of impurities in the gas, improving the filtration effect.

[0040] In some embodiments of this utility model, a pressure tank 26 is also provided in the spray chamber 2. The pressure tank 26 passes through several partitions. The spray pipe 24 is connected to the pressure tank 26. The pressure tank 26 atomizes the liquid in the spray pipe 24, causing impurities in the exhaust gas to fall rapidly and enter the filter chamber 3 for filtration.

[0041] In some embodiments of this utility model, the exhaust module 4 includes a drive motor 41 and an exhaust fan 42. The exhaust fan 42 is located directly above the spray chamber 2, and its horizontal height is greater than that of the spray pipe 24. The exhaust fan 42 further prevents the exhaust gas from spreading in the spray chamber 2, and at the same time causes the exhaust gas to move downward, thereby improving the filtration efficiency of the exhaust gas.

[0042] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
