[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1-Figure 4 The combined polyether production waste gas treatment device shown in the figure includes a shell 1, a catalyst box 9 is provided inside the shell 1, and a mounting mechanism is provided inside the catalyst box 9. The mounting mechanism includes a box door 10 slidably connected to one side of the catalyst box 9, and the box door 10 is located inside the catalyst box 9. One end is fixedly connected to a baffle 11, and the box door 10 is located outside the catalyst box 9. One end is rotatably connected to two adjustment knobs 13, and one end of the adjustment knob 13 is fixedly connected to a rotating rod 14. The outer surface of the rotating rod 14 is evenly arranged with a plurality of gears 15. The outer surface of the rotating rod 14 is slidably connected to a plurality of sleeve plates 16. The inner wall of the sleeve plate 16 is provided with a rack 17. One end of the sleeve plate 16 is fixedly connected There is an elastic part 18, and the end of the sleeve 16 away from the elastic part 18 is fixedly connected with an insert 19. By turning the adjusting knob 13, the rotating rod 14 can be driven to rotate, and the gear 15 can be rotated at the same time. The engagement of the gear 15 with the rack 17 drives the sleeve 16 to move, so that the insert 19 can be inserted into the catalyst box 9 to complete the fixation of the catalyst 12. When disassembling, the baffle 11 can be pulled out by the reverse operation, so that the catalyst 12 can be replaced to ensure the use effect of the catalyst 12. The process of replacing the catalyst 12 by this method is simple and quick, thereby improving the efficiency of exhaust gas treatment in the process of combined polyether production.
[0021] An air inlet 2 is provided at one end of the shell 1, and an exhaust port 3 is provided at the end of the shell 1 away from the air inlet 2. A plurality of inspection doors 4 are provided on one side of the shell 1. The plurality of inspection doors 4 are respectively coordinated with the spray mechanism, the filtering mechanism and the catalyst box 9. When a problem occurs in one of the components, the inspection door 4 can be opened for maintenance.
[0022] A spray mechanism is provided inside the shell 1, and the spray mechanism includes a spray head 5 arranged at the top of the shell 1. A drainage groove 6 is provided at the bottom end of the shell 1 directly below the spray head 5. The spray mechanism is located on one side of the air inlet 2. The spray mechanism can wash away most of the particulate matter in the exhaust gas and prevent large particles of waste from clogging the filter mechanism and affecting the filtering effect of the filter mechanism.
[0023] A filtering mechanism is provided inside the housing 1, and the filtering mechanism includes a plurality of filter plates 7 fixedly installed inside the housing 1. The filtering mechanism can isolate particulate waste in the exhaust gas to prevent these particulate waste from blocking the holes of the catalyst 12, affecting the passage of the exhaust gas, and thus affecting the efficiency of the exhaust gas treatment. A collecting plate 8 is fixedly installed inside the housing 1. The collecting plate 8 is located on one side of the filtering mechanism and close to the side of the exhaust port 3. The collecting plate 8 can collect the filtered exhaust gas and send it to the catalyst box 9.
[0024] A catalyst 12 is provided inside the catalytic box 9. The catalyst 12 is located inside the baffle 11. The waste gas generated in the production of the combined polyether is treated by catalytic combustion. Honeycomb activated carbon is used as the catalyst 12 to treat the waste gas. The activated carbon catalyst 12 can also be recycled and reused, saving the cost of activated carbon.
[0025] The rack 17 is meshed with the gear 15, and the plug 19 is matched with the socket provided on the inner wall of the catalyst box 9 through the meshing between the rack 17 and the gear 15. The number of the sleeve 16, the rack 17, the elastic member 18 and the plug 19 is the same as that of the gear 15. When the plug 19 is located at the socket, the elastic member 18 can use its own elastic force to pop out the plug 19, so that the plug 19 cooperates with the socket, and the box door 10 and the catalyst 12 connected to the box door 10 are fixed in the catalyst box 9, which is convenient for treating the waste gas generated in the production of the combined polyether. The sleeve 16 is slidably connected to the inside of the baffle 11 and is restricted by the groove inside the baffle 11, which prevents the plug 10 from falling off while also playing a guiding role.
[0026] Working principle: The waste gas generated in the production of combined polyether is discharged into the device from the air inlet 2. The waste gas is first cleaned by a spray mechanism to remove most of the particulate matter, and then the particulate matter in the waste gas is blocked by a filtering mechanism. Finally, the waste gas will enter the catalytic box 9 through the collecting plate 8. The waste gas will first cooperate with the catalyst 12 in the catalytic box 9, and then enter the combustion zone. The harmful substances or gases in the waste gas can be removed by the catalytic combustion method. Finally, the treated waste gas will be discharged from the exhaust port 3. When replacing the catalyst 12 that has been used for a long time, you only need to turn the adjusting knob 13 to cancel the match between the plug 19 and the socket, then you can pull out the baffle 11 and replace it with a new catalyst 12. The used catalyst 12 can also be desorbed by heating, so that the catalyst 12 can be reused, effectively saving the cost of the catalyst 12.
