At present, inhalable particulate matter has become an important source of harm to air quality, and volatile organic compounds (VOCs) are a major source of inhalable particulate matter. At present, VOCs mainly come from industrial production. In various occasions where organic solvents are used, such as painting, printing, metal degreasing and degreasing, adhesives, volatile organic compounds are constantly polluting the air.

[0003] Prior art includes an invention patent with authorization publication number CN105194965B, which discloses a VOCs waste gas treatment device. The inventor discovered in daily use of the above-mentioned products that the waste gas treatment mechanism often needs to be water-cooled to recycle its excess heat during use, and the flow of the water-cooling liquid is often coordinated with the flow of the waste gas. The gas flow controls the flow of the water-cooling liquid, and a sealing gasket needs to be installed on the inner wall of the gas channel. The sealing gasket is prone to aging due to long-term exposure to the waste gas, and continuous mechanical cooperation makes it more prone to mechanical aging, so the seal needs to be replaced. Since the sealing ring is installed on the inner wall of the gas channel and the mechanically coordinated push rod is in the gas channel, the space is too small to be directly disassembled.

[0032] Reference Figure 3 and Figure 4 The pre-clamping component 3 includes a sliding ring 31 slidably connected to the arc surface of the water outlet pipe 7. Two identical arc-shaped clamping plates 33 are arranged on one side of the sliding ring 31. Pre-clamping is performed when an external water pipe is connected. The external water pipe is inserted into the water outlet pipe 7, and the sliding ring 31 is dragged. The arc-shaped clamping plates 33 on both sides clamp the external water pipe through the tightening mechanism. Square grooves 32 are opened on both sides of the front of the sliding ring 31. A threaded rod 34 is arranged on the inner wall of the square groove 32 on one side. The threads at both ends of the threaded rod 34 are opposite. One side of the threaded rod 34 passes through the sliding ring 31. The threaded rod 34 and the arc-shaped clamping plate 33 are threadedly connected. The arc-shaped clamping plate 33 slides on the inner wall of the square groove 32.

[0033] Working principle:

[0034] When in use, first wind the heat dissipation copper tube around the air outlet pipe 4, and then connect the two ends of the heat dissipation copper tube to the water outlet pipe 7 and the water inlet pipe 8 with the help of a circulation pump and a pipeline. The water inside the heat dissipation copper tube can enter the water inlet pipe 8 and exit the water outlet pipe 7 through the circulation pump to achieve a circulation effect, and then utilize this to achieve the effect of heat energy utilization, so that the eardrum 11 on the round cover 6 is deformed, pushing the top rod 10 in the gas channel 9 to move to the left, and the exhaust gas enters from the air inlet pipe 5 under the left sealing block 15, passes through the gas channel 9, and is finally introduced from the air outlet pipe 4 into the exhaust gas treatment mechanism 16 for treatment (since the exhaust gas treatment mechanism 16 is an existing conventional technology, its principle will not be described in detail here), thereby ensuring The exhaust gas can be thermally treated in advance and then utilized. When no water enters, the first spring 12 is reset, so that the push rod 10 contacts the sealing ring 14 in the installation groove 13, thereby preventing the exhaust gas from going out, thereby avoiding the problem of heat energy consumption caused by the exhaust gas heat energy entering the exhaust gas treatment mechanism without being treated. When removing the sealing ring 14 in the installation groove 13, the right sealing block 1 and the left sealing block 15 are separated by a screwdriver, and the pushing block 232 is pushed to make the pushing block 232 move in the rectangular groove 21, so that the triangular block 231 moves up, and the disassembly rod 22 moves up. At the same time, the sliding piece 235 in the first auxiliary groove 233 slides in the second auxiliary groove 234, so that it slides on the circular rod 236. The disassembly rod 22 in the rectangular groove 21 is pushed upward, so that the sealing ring 14 in the installation groove 13 is pushed up and separated from the installation groove 13. The second spring 24 is set to reset it. The third spring 237 is set to reset the push block 232. When the external water pipe is connected, it is pre-clamped. The external water pipe is inserted into the water outlet pipe 7, the sliding ring 31 is dragged, and the threaded rod 34 in the square groove 32 is rotated to make the arc plates on both sides move closer to the center, so that the arc clamping plates 33 on both sides clamp the external water pipe. The short rod 35 is set to improve the stability of the arc plates when moving.
