[0002] The methyl salicylate production waste gas treatment device is a waste gas purification system specifically designed for the methyl salicylate production process. Its main purpose is to collect and treat waste gases containing volatile organic compounds, acidic substances, and other harmful components emitted during production, preventing their direct release into the atmosphere. This device ensures that waste gas emissions meet national and local environmental standards, reduces the potential impact of waste gases on the surrounding air environment, ecosystems, and human health, and helps production enterprises achieve environmental compliance and meet green production requirements.

[0003] In existing technologies, during the use of waste gas treatment devices, the contact between the spray liquid and the waste gas is not uniform and complete enough when spraying waste gas, which affects the spraying effect and makes it inconvenient to replace the filter element used to purify the waste gas. Therefore, improvements are needed. Utility Model Content

This connecting mechanism facilitates the disassembly of the connecting seat.

[0006] Preferably, there are multiple through holes, which are evenly distributed inside the frame. The through holes are designed to allow air to flow through them.

[0007] Preferably, the spraying mechanism includes a rotating ring, which is rotatably sleeved inside the cylinder. A fixed pipe is fixedly connected to the inner side of the rotating ring, and multiple evenly distributed nozzles are fixedly connected to the lower end of the fixed pipe. A mounting base is fixedly connected to the left inner wall of the cylinder, and a motor is fixedly installed inside the mounting base.

[0017] Please see Figure 1 , Figure 2 , Figure 3The spraying mechanism 8 includes a rotating ring 81, which is rotatably sleeved inside the cylinder 1. A support ring 82 is rotatably sleeved inside the rotating ring 81. The support ring 82 is fixedly connected to the cylinder 1. The support ring 82 is designed to provide rotatable support for the rotating ring 81. A fixing pipe 83 is fixedly connected to the inner side of the rotating ring 81. Multiple evenly distributed spray nozzles 84 are fixedly connected to the lower end of the fixing pipe 83. A mounting base 85 is fixedly connected to the inner left side of the cylinder 1. An electric spray nozzle is fixedly installed inside the mounting base 85. The output end of the motor 86 is rotatably connected to the mounting base 85. The lower end of the output end of the motor 86 is fixedly connected to the gear 87. The outer side of the gear 87 is meshed with the gear ring 88. The gear ring 88 is fixedly connected to the rotating ring 81. By designing the meshing of the gear 87 and the gear ring 88, the rotating ring 81 can be rotated when the gear 87 rotates. The input pipe 89 is rotatably sleeved inside the fixed pipe 83. The input pipe 89 is fixedly connected to the cylinder 1. By designing the spray mechanism 8, the exhaust gas can be sprayed for treatment.

[0018] Please see Figure 1 , Figure 2 , Figure 4 The connecting mechanism 9 includes an arc-shaped groove 91. The arc-shaped groove 91 is opened inside the housing 7. An arc-shaped block 92 is slidably connected inside the arc-shaped groove 91. A connecting seat 93 is slidably sleeved on the outside of the arc-shaped block 92.

[0019] The specific implementation process of this utility model is as follows: During use, exhaust gas is input into the cylinder 1 through the air inlet pipe 5, and at the same time, the input pipe 89 inputs spray liquid into the fixed pipe 83.

[0020] After being treated by spraying, the exhaust gas is adsorbed by the adsorption layer 3. Then, the gas is input into the housing 7 through the connecting pipe 6. The gas flows through the through hole 12 and can be purified again by the filter element 13 to improve the treatment effect. Finally, the treated exhaust gas is discharged through the exhaust port 10.

[0021] When the connecting seat 93 is pulled upward, the connecting seat 93 moves the arc-shaped block 92. The arc-shaped block 92 slides along the arc surface of the arc groove 91. When the arc-shaped block 92 is squeezed, it will move horizontally. The arc-shaped block 92 will slide along the fixed rod 94. The arc-shaped block 92 will squeeze the spring 95, and finally the arc-shaped block 92 can be separated from the arc groove 91. Then the connecting seat 93 can be pulled off the housing 7, and then the filter element 13 can be taken out from the frame 11 for easy replacement.
