When the exhaust gas moves upward, it will pass through the reaction device 4 for purification and neutralization reaction, and finally the generated gas is discharged through the input pipe 25 to the exhaust pipe 26.

[0021] Furthermore, the easy-to-disassemble component 5 includes a mounting groove 51, and the two mounting grooves 51 are both arranged inside the reaction box 21. The outside of the fixed frame 3 is fixedly connected to two connecting plates 52. The connecting plates 52 are made of steel, which has the advantages of high strength, wear resistance and corrosion resistance. The inside of the two connecting plates 52 is provided with a limiting groove 53, and the inside of the two mounting grooves 51 is rotatably connected with a gear 54. The inside of the reaction box 21 is rotatably connected with two hand wheels 57, and one end of the two hand wheels 57 extends to the inside of the mounting groove 51 and is fixedly connected to the corresponding gear 54. One side of the two gears 54 is meshed with a rack 55. The tops of the two racks 55 are fixedly connected to the limiting blocks 56, and the tops of the two limiting blocks 56 extend to the inside of the limiting groove 53. The inside of the two mounting grooves 51 is provided with a positioning groove 59, and the outside of the two hand wheels 57 is fixedly connected with a telescopic positioning rod 58, and one end of the two telescopic positioning rods 58 extends to the inside of the positioning groove 59. When the reaction device 4 is used to a certain extent, it needs to be disassembled and cleaned to ensure that the reaction device 4 is used to a certain extent. In order to ensure a better subsequent exhaust gas emission effect, the worker rotates the hand wheel 57 in the forward direction. When the hand wheel 57 rotates, the gear 54 connected thereto is driven to rotate. When the gear 54 rotates, the rack 55 on one side is driven to move downward, thereby driving the limit block 56 at the top of the rack 55 to disengage from the inside of the limit groove 53. At this time, the connecting plate 52 is in an active state, and the reaction device 4 can be taken out of the reaction box 21 for cleaning. After cleaning, the reaction device 4 is inserted into the installation groove 51 through the connecting plate 52, and then the hand wheel 57 is rotated in the reverse direction, and the rack 55 is driven to move upward through the gear 54, so that the limit block 56 at the top of the rack 55 extends to the inside of the limit groove 53. At this time, the reaction device 4 is in a fixed state. In order to prevent the reaction device 4 from remaining stable and not sliding down during use, at this time, the telescopic positioning rod 58 is provided, and one end of the telescopic positioning rod 58 is extended to the positioning groove 59, so that the hand wheel 57 no longer rotates. Thus, the reaction device 4 can achieve the effect of regular cleaning and improve the subsequent use effect of the reaction device 4.

[0022] In summary: when in use, the exhaust gas is passed into the interior of the reaction box 21 through the air inlet pipe 27, and the suction pump 24 is started. A negative pressure is formed inside the reaction box 21 through the suction pump 24, and the exhaust gas moves upward. When the exhaust gas moves upward, it will pass through the reaction device 4 for purification and neutralization reaction, and finally the generated gas is discharged through the input pipe 25 to the discharge pipe 26, and the waste liquid and the like flow to the interior of the sedimentation tank 22. When the reaction device 4 is used to a certain extent, it needs to be disassembled and cleaned to ensure that the subsequent exhaust gas emission effect is better. The worker turns the hand wheel 57 forward. When the hand wheel 57 rotates, it will drive the gear 54 connected to it to rotate. When the gear 54 rotates, it will drive the rack 55 on one side to move downward, thereby driving the limit position at the top of the rack 55. The block 56 is out of the limiting groove 53. At this time, the connecting plate 52 is in an active state, and the reaction device 4 can be taken out of the reaction box 21 for cleaning. After cleaning, the reaction device 4 is inserted into the installation groove 51 through the connecting plate 52, and then the hand wheel 57 is rotated in the opposite direction to drive the rack 55 to move upward through the gear 54, so that the limiting block 56 at the top of the rack 55 extends into the limiting groove 53. At this time, the reaction device 4 is in a fixed state. In order to prevent the reaction device 4 from remaining stable and not sliding down during use, at this time, the telescopic positioning rod 58 is set, and one end of the telescopic positioning rod 58 is extended to the positioning groove 59, so that the hand wheel 57 no longer rotates. In this way, the reaction device 4 can be cleaned regularly and the subsequent use effect of the reaction device 4 can be improved.
