[0021] The treatment method of dimethyl succinate waste gas is as follows:

[0022] S1: The external exhaust gas discharge device sends the exhaust gas into the inner combustion chamber through the exhaust pipe. The user controls the flamethrower to start through the device system, and uses the ejected flame to perform high-temperature combustion treatment on the harmful components of the exhaust gas. The catalyst block on the loading rack can speed up the treatment speed. The air intake machine regularly sends external oxygen into the inner combustion chamber. At the same time, the hot air generated between the inner combustion chamber and the outer shell will be drawn out by the circulating fan and sent to the connecting pipe. The hot air flow in the connecting pipe will enter the preheating pipe, and the hot air will flow back into the outer shell through the preheating pipe. The hot air in the preheating pipe is used to preheat the exhaust gas in the exhaust pipe;

[0023] S2: The treated exhaust gas in the inner combustion chamber will enter the first treatment cylinder through the air pipe, and the pump will deliver the absorption liquid in the storage cylinder to the connecting frame, and the liquid in the connecting frame will be sprayed out through the nozzles on the three spray rods, and the sprayed medicine mist will be used to perform the first heavy absorption of the harmful components of the exhaust gas in the first treatment cylinder. The first solenoid valve tube and the second solenoid valve tube will be opened regularly to discharge the residual night. During this process, the motor will drive the transmission rod to rotate, and the transmission rod will perform periodic forward or reverse rotation. The transmission rod will drive the threaded lifting frame to move synchronously in the first treatment cylinder, and at the same time, the power gear on the transmission rod will drive the meshing gear ring to rotate, and at the same time, the gear ring will drive the corresponding second treatment cylinder to rotate synchronously, and the second treatment cylinder will drive the inner gas cylinder, the moving column and the spray rod to rotate synchronously, and the bottom of the second treatment cylinder will rotate on the rotating joint;

[0024] S3: During the upward movement of the lifting frame, the second treatment cylinder will drive the fixed blades distributed at equal angles to rotate synchronously. The fixed blades can accelerate the exhaust gas in the first treatment cylinder to enter the second treatment cylinder. At the same time, the fixed blades can accelerate the convection of the exhaust gas in the first treatment cylinder to provide a treatment effect. When the lifting frame moves upward, it will pull the moving column to move synchronously, so that the extrusion plug at the bottom of the moving column moves synchronously in the inner cylinder, thereby generating negative pressure, further accelerating the exhaust gas to enter the second treatment cylinder, and the nozzle at the bottom of the spray rod will move out of the moving column, and the sprayed medicine mist will be used to treat the residual waste gas in the second treatment cylinder. The harmful components of the exhaust gas are processed for the second time. At this time, the exhaust gas will pass through the filter plate for particle filtration. When the moving column drives the guide groove to move upward to the set position, the inclined surface at the bottom of the guide groove will exert pressure on the force-bearing rod, so that the force-bearing rod drives the rotating disk to rotate, and the limit block at the bottom of the rotating disk will pull the corresponding rotating plate to rotate synchronously. At this time, the rotating plate will drive the corresponding sealing plate to rotate synchronously through the connecting rod. The cleaning plate at the end of the sealing plate will clean the filter plate. At the same time, the sealing plate will be embedded in the air flow port of the air inlet plate to play a sealing role. At this time, the force-bearing rod just passes through the one-way limit tooth at the bottom of the guide groove;

[0025] S4: After that, the transmission rod will drive the lifting frame to move downward. As can be seen from the previous steps, the second treatment cylinder is in a closed state. The moving column will drive the extrusion plug to move downward in the inner cylinder to squeeze the waste gas and medicine mist. By pressurizing, the distance between the waste gas molecules and the medicine mist is reduced to further improve the treatment effect. The second treatment cylinder and the exhaust base are connected through the docking joint. At this time, the air pressure in the exhaust base increases synchronously. When the air pressure reaches the set value, the gas will push the exhaust plug to move upward and open, and the elastic telescopic rod will move synchronously and elastically. At this time, the waste gas treated in the exhaust base can be discharged into the tail end pipe;

[0026] S5: In the process of the moving column driving the guide groove to move downward and return to its original position, the inclined groove at the top of the guide groove will push the force-bearing rod again, so that the force-bearing rod drives the rotating disk to return to rotation, and the force-bearing rod passes through the one-way limiting tooth at the top of the guide groove, thereby opening the air flow port on the air intake plate again, so that the exhaust gas in the first treatment cylinder can enter the second treatment cylinder again for the next cycle.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: the succinylsuccinate dimethyl ester waste gas treatment device and the treatment method thereof are provided with a pressurized interstitial exhaust structure, which can effectively prolong the contact time between the waste gas and the treatment liquid in the device during use, and the pressurization of the device can reduce the distance between the molecules in the waste gas and the liquid components, thereby further improving the treatment effect of the device on harmful components in the waste gas. The specific contents are as follows:

[0028] 1. An air intake plate is fixedly connected to the outer wall of one side of the fixed blade close to the sealing plate. The air intake plate is fixedly installed in the through-hole on the side wall of the second treatment cylinder. The air flow opening of the air intake plate is on the rotation track of the sealing plate for subsequent sealing. The upper end of the connecting rod is fixedly penetrated through the rotating plate. A limit block is fitted in the slide groove of the rotating plate. The upper end surface of the limit block is fixedly connected to the bottom edge of the rotating disk, so that the rotating disk can drive the rotating plate to rotate through the limit block. At this time, the rotating plate will drive the connecting rod and the sealing plate to rotate synchronously, so that the sealing plate can block the air flow opening of the air intake plate;

[0029] 2. A cleaning plate is slidably inserted on the side of the sealing plate away from the fixed blade, and a thrust spring is fixedly connected between the outer wall of the cleaning plate and the inner wall of the sealing plate. The side of the cleaning plate away from the thrust spring is fitted on the corresponding filter plate. The filter plate has an arc-shaped structure, and the center of the filter plate is on the axis of the connecting rod. The four sides of the filter plate are fixedly connected to the inner wall of the first treatment cylinder, and the filter plates are distributed at equal angles between the first treatment cylinder and the inner air cylinder, so that the sealing plate can drive the cleaning plate to move synchronously. At this time, the cleaning plate cleans the filter plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The treatment method of dimethyl succinate waste gas is as follows:

[0058] S1: The external exhaust gas discharge device sends the exhaust gas into the inner combustion chamber 3 through the exhaust pipe 10. The user controls the flamethrower 4 to start through the device system, and uses the ejected flame to perform high-temperature combustion treatment on the harmful components of the exhaust gas. The catalyst block on the loading rack 5 can speed up the treatment speed. The air intake machine 2 regularly sends external oxygen into the inner combustion chamber 3. At the same time, the hot air generated between the inner combustion chamber 3 and the outer shell 1 will be drawn out by the circulating fan 7 and sent to the connecting pipe 8. The hot air flow in the connecting pipe 8 will enter the preheating pipe 9, and the hot air will flow back into the outer shell 1 through the preheating pipe 9. The hot air in the preheating pipe 9 is used to preheat the exhaust gas in the exhaust pipe 10;

[0059] S2: The treated exhaust gas in the inner combustion chamber 3 will enter the first treatment cylinder 11 through the gas pipe 6, and the pump 13 will deliver the absorption liquid in the storage cylinder 12 to the connecting frame 14, and the liquid in the connecting frame 14 will be sprayed out through the nozzles on the three spray rods 33, and the sprayed medicine mist will be used to perform the first heavy absorption of the harmful components of the exhaust gas in the first treatment cylinder 11. The first solenoid valve tube 18 and the second solenoid valve tube 19 will be opened regularly to discharge the residual night. During this process, the motor 15 will drive the transmission rod 16 to rotate, and the transmission rod 16 will perform periodic forward or reverse rotation. The transmission rod 16 will drive the threaded lifting frame 35 to move synchronously in the first treatment cylinder 11, and at the same time, the power gear 23 on the transmission rod 16 will drive the meshing gear ring 24 to rotate, and at the same time, the gear ring 24 will drive the corresponding second treatment cylinder 25 to rotate synchronously, and the second treatment cylinder 25 will drive the inner gas cylinder 34, the moving column 2901 and the spray rod 33 to rotate synchronously, and the bottom of the second treatment cylinder 25 will rotate on the rotatably connected docking joint 26;

[0060] S3: During the upward movement of the lifting frame 35, the second treatment cylinder 25 will drive the fixed blades 2701 distributed at equal angles to rotate synchronously. The fixed blades 2701 can accelerate the exhaust gas in the first treatment cylinder 11 to enter the second treatment cylinder 25. At the same time, the fixed blades 2701 can accelerate the exhaust convection in the first treatment cylinder 11 to provide a treatment effect. When the lifting frame 35 moves upward, it will pull the moving column 2901 to move synchronously, so that the extrusion plug 2902 at the bottom of the moving column 2901 moves synchronously in the inner air cylinder 34, thereby generating negative pressure, further accelerating the exhaust gas to enter the second treatment cylinder 25, and the nozzle at the bottom of the spray rod 33 will be moved out of the moving column 2901, and the sprayed medicine mist will be used to treat the harmful components of the exhaust gas remaining in the second treatment cylinder 25. Heavy processing, at this time, the exhaust gas will pass through the filter plate 28 for particle filtration, when the movable column 2901 drives the guide groove 2903 to move upward to the set position, the inclined surface at the bottom of the guide groove 2903 will apply pressure to the force rod 30, so that the force rod 30 drives the rotating disk 31 to rotate, and the limit block 32 at the bottom of the rotating disk 31 will pull the corresponding rotating plate 2707 to rotate synchronously, at this time, the rotating plate 2707 will drive the corresponding sealing plate 2702 to rotate synchronously through the connecting rod 2706, and the cleaning plate 2705 at the end of the sealing plate 2702 will clean the filter plate 28, and at the same time, the sealing plate 2702 will be embedded in the air flow port of the air inlet plate 2703 to play a sealing role, and at this time, the force rod 30 just passes through the one-way limit tooth 2904 at the bottom of the guide groove 2903;

[0061] S4: Then the transmission rod 16 will drive the lifting frame 35 to move downward. It can be seen from the previous steps that the second treatment cylinder 25 is in a closed state. The moving column 2901 will drive the extrusion plug 2902 to move downward in the inner cylinder 34 to squeeze the waste gas and the medicine mist. By pressurizing, the distance between the waste gas molecules and the medicine mist is reduced to further improve the treatment effect. The second treatment cylinder 25 and the exhaust base 17 are connected through the docking joint 26. At this time, the air pressure in the exhaust base 17 increases synchronously. When the air pressure reaches the set value, the gas will push the exhaust plug 20 to move upward and open, and the elastic telescopic rod 21 moves synchronously and elastically. At this time, the waste gas treated in the exhaust base 17 can be discharged into the tail end pipe 22;

[0062] S5: In the process of the moving column 2901 driving the guide groove 2903 to move downward and return to its original position, the inclined groove at the top of the guide groove 2903 will push the force-bearing rod 30 again, so that the force-bearing rod 30 drives the rotating disk 31 to return to rotation, and the force-bearing rod 30 passes through the one-way limiting tooth 2904 at the top of the guide groove 2903, thereby opening the air flow port on the air intake plate 2703 again, so that the exhaust gas in the first treatment cylinder 11 can enter the second treatment cylinder 25 again for the next cycle.
