The number of catalyst plates 26, catalyst screws 27, and catalyst motors 28 is two. A carbon monoxide catalyst is stored in the storage box 22. The carbon monoxide CO catalyst is a catalyst for degrading CO. It converts CO into harmless substances through catalytic oxidation reactions, reduces CO emissions, and protects the environment and health. The working principle of the CO catalyst is mainly based on the adsorption of the catalyst on the reactants and the surface chemical reaction. In the oxidation reaction of CO, CO is adsorbed on the surface of the catalyst and reacts with oxygen molecules on the surface to form harmless substances such as carbon dioxide and water.Through the action of the catalyst, the processing efficiency of CO has been significantly improved. A battery 29 and a driver 30 are provided on one side of the storage box 22. The model of the driver 30 is L298N.

It can drive inductive loads such as high-power DC motors, stepper motors, solenoid valves, etc., especially its input end can be directly connected to the single-chip microcomputer, so that it is very convenient to be controlled by the single-chip microcomputer. When driving the DC motor, the stepper motor can be directly controlled, and the forward and reverse rotation of the motor can be realized. To realize this function, it only needs to change the logic level of the input end. In order to avoid the interference of the motor to the single-chip microcomputer, this module adds an optocoupler for photoelectric isolation, so that the system can work stably and reliably. During use, harmful gases are treated in the spray box 13, but carbon monoxide gas will still exist in the air. A carbon monoxide catalyst is stored in the storage box 22. The top catalyst motor 28 drives the top catalyst screw 27 to rotate, so that the top catalyst plate 26 opens and the carbon monoxide catalyst enters the catalyst box 21 to treat the carbon monoxide gas. The bottom catalyst motor 28 drives the bottom catalyst screw 27 to rotate, so that the bottom catalyst plate 26 opens, and the used carbon monoxide catalyst is recycled and processed.

The operation of the equipment effectively reduces harmful substances in the exhaust gas, thereby reducing harmful substances when the exhaust gas is discharged, avoiding air pollution by carbon monoxide, and protecting the environment to create a healthy living environment.

[0028] How this utility works:

[0029] During use, the exhaust fan 5 rotates to exhaust air, so that the internal gas is discharged, and the suction fan 7 rotates to suck air, so that the outside air is sucked into the interior so that there is fresh air inside. The fan box 1 can be installed with the exhaust fan 5 and the suction fan 7 in various positions. The exhaust fan pipe 6 and the suction fan pipe 8 can be spliced ​​and extended according to the internal space. The internal air enters the spray box 13 through the exhaust pipe 9, and the exhaust pipe 9 is heated by the heating wire 11. The spray water pump 17 is used to pump water from time to time. The water enters the exhaust pipe 9 through the steam water pipe 12 to generate steam, so that the harmful gases in the air are combined with the water vapor to form large particles, which sink to the bottom of the exhaust pipe 9 due to weight, thereby reducing the composition and concentration of the harmful gases. When multiple exhaust fans 5 are running, a large amount of gas will be generated. The spray water pump 17 rotates to pump water, so that the nozzle in the spray plate 16 sprays water, thereby quickly reducing the composition and concentration of the harmful gases. The exhaust pipe can be cleaned by the sewage recovery box 15. 9. The sewage in the spray box 13 is recycled and processed. The harmful gas is processed in the spray box 13. Carbon monoxide gas will still exist in the air. A carbon monoxide catalyst is stored in the storage box 22. The top catalyst motor 28 drives the top catalyst screw 27 to rotate, so that the top catalyst plate 26 is opened to allow the carbon monoxide catalyst to enter the catalyst box 21 to process the carbon monoxide gas. The bottom catalyst motor 28 drives the bottom catalyst screw 27 to rotate, so that the bottom catalyst plate 26 is opened, and the used carbon monoxide catalyst is recycled and processed. The catalytic recovery box 24 is pulled out to clean the used carbon monoxide catalyst storage. The equipment is operated to replace the gas in the production space, thereby avoiding hypoxia caused by the lack of oxygen in the production space due to the lack of gas circulation. Air pollution has gradually affected human health, and carbon monoxide pollution, which belongs to air pollution, also harms people because of its commonness. Harmful gases are treated by equipment to protect the environment.
