DETAILED DESCRIPTION

[0015] like Figure 1-5As shown: an exhaust gas treatment device for a workshop, comprising a filter barrel 1, the bottom of the filter barrel 1 is funnel-shaped and is fixedly connected to a sewage pipe 3 in the center, and a valve 4 is installed on the sewage pipe 3; a water pump 5 is provided on the front side of the filter barrel 1, the input end of the water pump 5 is fixedly connected to the bottom of the outer wall of the filter barrel 1, the input end of the water pump 5 is connected to the inside of the filter barrel 1, and the output end of the water pump 5 is fixedly connected to a water delivery pipe 6, which extends upward along the front side of the outer wall of the filter barrel 1, and the rear side wall of the water delivery pipe 6 is fixedly connected to equidistantly distributed branch pipes 7, which penetrate the outer wall of the filter barrel 1 and extend to the inside of the filter barrel 1, and the outer wall of the branch pipe 7 is fixedly connected to a coil 8, which is in the shape of multiple concentric rings, and a plurality of evenly distributed spray ports 9 are provided at the bottom of the coil 8, and an exhaust fan 10 is provided on the left side of the filter barrel 1, and the input end of the exhaust fan 10 is fixedly connected to the exhaust fan 10. The air pipe 11, the other end of the exhaust pipe 11 extends to the top of the filter barrel 1 and is fixedly connected to the filter barrel 1, the top of the filter barrel 1 is fixedly connected with a dosing pipe 13, and the dosing pipe 13 is installed with a valve 2 14, and the bottom of the right side wall of the filter barrel 1 is fixedly connected with an air intake pipe 15, and the right end of the air intake pipe 15 has a filter tube 16 and a filter tube 2 17, and the filter tube 16 and the filter tube 2 17 are parallel to each other, and the left ends and right ends of the filter tube 16 and the filter tube 2 17 are fixedly connected with a connecting pipe 18, and the connecting pipe 18 at the left end is fixedly connected with the air intake pipe 15, and the outer walls of the filter tube 16 and the filter tube 2 17 are fixedly connected with a plurality of equally spaced dry filter boxes 19, and a pull-out filter core 20 is slidably inserted in the dry filter box 19, and valves 3 21 are installed at both ends of the filter tube 16 and the filter tube 2 17.

[0016] Four evenly distributed legs 2 are fixedly connected to the bottom of the outer wall of the filter barrel 1 , the legs 2 are fixedly connected to the bottom of the water pump 5 , and the output end of the exhaust fan 10 is fixedly connected to the air outlet pipe 12 .

[0017] When the workshop waste gas needs to be treated, the valve 2 14 can be opened, and the medicine solution can be injected into the filter barrel 1 through the medicine adding pipe 13, and the medicine solution is ready for subsequent wet filtration in the filter barrel 1;

[0018] First, the exhaust fan 10 is started. The exhaust fan 10 starts to extract the gas in the filter barrel 1 through the exhaust pipe 11 to generate negative pressure to extract the external exhaust gas. The exhaust gas first enters the filter tube 16 and the filter tube 2 17 from the connecting pipe 18 at the right end. In these two parallel filter tubes, the exhaust gas will pass through the pull-out filter element 20 in the dry filter box 19 for preliminary dry filtration;

[0019] The water pump 5 starts to work, extracts the liquid medicine in the filter barrel 1, and transports it to each branch pipe 7 through the water pipe 6. Then, the liquid medicine is sprayed out through the spray port 9 on the coil 8 to spray the waste gas that has been dry-filtered. The sprayed liquid medicine contacts the waste gas to react and wet-filter the waste gas. The filtered gas continues to rise, while the liquid medicine falls into the bottom of the filter barrel 1.

[0020] The exhaust gas that has been subjected to dry and wet dual filtration is discharged from the air outlet pipe 12 along the exhaust pipe 11.

[0021] When the pull-out filter element 20 needs to be replaced or cleaned, the valves 3 21 at both ends of the filter tube 1 16 or the filter tube 2 17 can be closed to keep the filter tube 1 16 or the filter tube 2 17 unblocked and working normally, thereby ensuring the continuous filtering of the exhaust gas. The pull-out filter element 20 is a prior art device. The pull-out filter element 20 in the utility model is a prior art device, and its structure will not be described in detail. The utility model only protects the mechanical part, and the functions related to it realized by the software control part are not within the protection scope of the utility model.
