A pull rod 19 is fixedly connected to the lower end of the movable column 17. A fixing hole 20 is provided on the upper surface of the fixing frame 11. Figure 5 As shown, the structure is used to pull the pull rod 19 upwards to disengage the lower end of the pull rod 19 and the limit plate 21 from the fixing hole 20, so that it can be pulled out of the fixing frame 11 through the handle 15, and the first filter plate 12, the second filter plate 13 and the third filter plate 14 in the fixing frame 11 are replaced to avoid long-term use affecting the filtering effect.

The pull rod 19 is inserted into the fixing hole 20 through the rebound action of the reset spring 18. The coordinated use of the reset spring 18 and the pull rod 19 facilitates the replacement of the first filter plate 12, the second filter plate 13 and the third filter plate 14.

[0030] The device solves the problem that the waste gas generated in the reactor is directly discharged into the air, which pollutes the environment, and is inconvenient to replace, which reduces the effect of waste gas filtering and cleaning, by using the waste gas treatment mechanism and the replacement components in combination.

[0031] Furthermore, the first filter plate 12, the second filter plate 13 and the third filter plate 14 are sequentially clamped in the fixing frame 11, and the fixing frame 11 is located on the right side of the partition plate 8. Figure 4 As shown, the structure is used to effectively intercept the waste gas and perform secondary filtration by alternately arranging the first filter plate 12, the second filter plate 13 and the third filter plate 14, thereby avoiding the impact of a large amount of waste gas discharge on the environment and production.

Figure 3 As shown, this structure is used to increase the contact area between the filtrate and the exhaust gas by adding a waterproof blowing fan 9, so that the water washing dust reduction effect is better.

[0033] Furthermore, an air outlet pipe 23 is fixedly connected to the upper surface of the right side of the processing chamber 3, a gas detector 24 is arranged on the inner wall of the air outlet pipe 23, a controller 26 is fixedly installed on the outer side of the air outlet pipe 23, the gas detector 24 is connected to the controller 26 via wires, an electronic valve 25 is fixedly installed in the air outlet pipe 23, and the electronic valve 25 is connected to the controller 26 via wires. Figure 3 As shown, the structure is used to detect the filtered gas through the gas detector 24 to detect whether the purified gas meets the emission standards, thereby sending a signal to the controller 26. The controller 26 compares the data of the discharged gas. When it meets the emission standards, the controller 26 sends a signal to control the electronic valve 25 to open.

[0034] Furthermore, the surface of the pull rod 19 is fixedly connected to a limit plate 21, and a sealing pad is provided at the bottom of the limit plate 21. The right surface of the fixing frame 11 is fixedly connected to a handle 15, and the handle 15 is C-shaped, which is convenient for the user to take out the fixing frame 11 for replacement. Figure 3 As shown, the structure is used to seal the feed port of the reactor body through a sealing gasket to prevent leakage of exhaust gas in the treatment chamber 3, and harmful particles contained in the exhaust gas can be filtered through the first filter plate 12, the second filter plate 13 and the third filter plate 14.

[0035] Working principle: When used, Figure 2 and Figure 3 As shown, the exhaust gas passes through the reactor body 1 through the air inlet pipe 2 and quickly enters the treatment chamber 3 with the assistance of the fan blades 5. The exhaust gas discharged from the air inlet pipe 2 is sprayed and washed with water through the cooperation of the spray pipe 6 and the nozzle 7. The exhaust gas enters the bottom of the treatment chamber 3. The filtrate at the bottom of the treatment chamber 3 greatly reduces the particulate matter content in the exhaust gas. By adding a waterproof blowing fan 9, the contact area between the filtrate and the exhaust gas can be increased, so that the water washing dust reduction effect is better; the exhaust gas passes through the right side of the partition plate 8 and passes through the first filter plate 12, the second filter plate 13 and the third filter plate 14 in turn. The interphase setting can effectively intercept the exhaust gas and perform secondary filtration, thereby avoiding the impact of a large amount of exhaust gas discharge on the environment and production. The gas after filtration is detected by the gas detector 24 to detect whether the purified gas meets the emission standards, thereby sending a signal to the controller 26. The controller 26 compares the data of the exhausted gas. When it meets the emission standards, it sends a signal to the controller 26 to control the electronic valve 25 to open. When it does not meet the standards, the controller 26 controls the electronic valve 25 to close and sends a signal to remind the staff. When it needs to be replaced, such as Figure 5As shown, by pulling the pull rod 19 upward, the lower end of the pull rod 19 and the limit plate 21 are disengaged from the fixing hole 20, so that they can be pulled out of the fixing frame 11 through the handle 15, and the first filter plate 12, the second filter plate 13 and the third filter plate 14 in the fixing frame 11 are replaced to avoid long-term use affecting the filtering effect. After the replacement is completed, the fixing frame 11 is inserted into the placement groove 10, and the pull rod 19 is released. The pull rod 19 is inserted into the fixing hole 20 through the rebound effect of the return spring 18, and the limit plate 21 is attached to the surface of the fixing frame 11. Through the coordinated use of the return spring 18 and the pull rod 19, it is convenient to replace the first filter plate 12, the second filter plate 13 and the third filter plate 14. The above is the entire working principle of the utility model.
