[0002] Waste gas treatment mainly refers to the treatment of industrial waste gas generated in industrial sites, such as dust particles, flue gas soot, odor gas, toxic and harmful gases. A large amount of waste gas is usually generated in the chemical manufacturing process. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot and production dust. Discharged into the atmosphere, it will pollute the air. These substances usually contain a lot of impurities and toxic substances, and these impurities and toxic substances cannot be filtered well and are directly discharged into the air, polluting the air and entering the human body through the respiratory tract in different ways. Some directly cause harm, and some have an accumulation effect, which will more seriously harm human health, and different substances will have different effects.

[0003] In the plastic processing waste gas treatment device disclosed in the Chinese utility model patent application publication specification CN212548794U, although the device can treat and collect waste gas and treat the filter screen, but this device can not only treat waste gas, but also perform secondary utilization of waste gas to preheat plastic, filter and purify waste gas, quickly replace it, and clean the waste gas discharge path, resulting in problems of harm to staff and low work efficiency. Therefore, we propose a new device to solve the above problems. Content of the Utility Model

[0015] 1. The structure of the present utility model is reasonable. When the thermoforming machine device works, the exhausted gas enters the first exhaust pipe, and then enters the spray box. The spray liquid is pumped up by the spray water pump, enters the spray pipe through the water distribution pipe, and is sprayed out through the spray head.

Therefore, the working efficiency and the service time of the equipment are improved through preheating.

[0016] 2. In the present utility model, by closing the valve of the first exhaust pipe, the hot water injected into the water inlet pipe is pumped by the water supply pump to clean the exhaust gas passage. This avoids the situation where the exhaust gas carries tiny plastic sticky particles when discharged, which would cause a certain mucosal covering on the inner surface of the exhaust gas pipeline, reducing the exhaust gas volume of the exhaust gas passage. Thus, the exhaust gas passage is cleaned, greatly improving the working efficiency and the working duration. The liquid in the spray box can be discharged and filled through the fixed pipe by the spray water pump. When the activated carbon plate has adsorbed exhaust gas for a certain period of time, the activated carbon cover plate can be directly pulled out for replacement and drying. When the ultraviolet lamp tube is damaged and needs to be repaired or replaced, the lamp socket cover plate is pulled out for repair and replacement. This avoids the need to disassemble the entire purification device for replacement when the exhaust gas purification device needs to be replaced during long-term exhaust gas purification, and the replacement time is too long. Therefore, quickly replacing the purification device greatly improves the working efficiency and facilitates the replacement by the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The working principle of this utility model:

[0029] During use, waste gas is discharged into the first exhaust pipe 2 when the thermoforming machine equipment 1 is working. The waste gas enters the spray box 3 through the first exhaust pipe 2. There is spray liquid inside the spray box 3, which is pumped up by the spray water pump 7 and shunted through the water distribution pipe 10 into the spray pipes 11, and sprayed out through the spray nozzles 12 to atomize and dilute the waste gas. The waste gas enters the adsorption box 14 through the second exhaust pipe 13, passes through the activated carbon plates 18, and the waste gas is adsorbed. The waste gas enters the ultraviolet lamp box 20 through the third exhaust pipe 19, and the ultraviolet lamp tubes 25 irradiate and crack the waste gas. The waste gas is discharged from the fourth exhaust pipe 26. The air monitoring structure 27 can monitor the discharged waste gas. If it does not meet the standards, it will issue an alarm and display the value, avoiding the direct discharge of untreated waste gas into the air, which causes pollution to the atmosphere, damage to the surrounding ecological environment, and harm to the health of the staff. The plastic enters the feed bin 37 and is evenly fed into the feed pipe 32 by the motor 39 driving the stirrer 40. The outer surface of the feed pipe 32 is sleeved with a heat conduction structure 33. The lower surface of the heat dissipation phosphorus 34 is tightly attached to the first exhaust pipe 2 for heat conduction, so that the heat preheats the plastic inside the feed pipe 32 through the heat conduction structure 33, avoiding too large a temperature difference when the plastic enters the interior of the thermoforming machine equipment 1, long time to heat to the melting state, wasting working time and resources, and reducing work efficiency. Therefore, the work efficiency and the equipment usage time are improved through preheating. After the thermoforming machine has been used for a period of time, cleaning is required. The valve on the upper surface of the left side of the first exhaust pipe 2 can be closed. There is a water inlet pipe on the upper surface of the water supply tank 30. The water inlet pipe injects hot water, and the hot water is pumped by the water supply pump 29 to clean the waste gas discharge path. The cleaned water can enter the spray box 3 and be discharged from the fixed pipe through the spray water pump 7 by rotating the three-way valve, avoiding the waste gas carrying tiny plastic sticky particles to cover the inner surface of the waste gas pipeline to a certain extent, reducing the exhaust volume of the waste gas discharge path, and thus cleaning the waste gas discharge path, greatly improving the work efficiency and the working duration. The liquid in the spray box 3 can be discharged and filled from the fixed pipe through the spray water pump 7. When the activated carbon plates 18 have adsorbed waste gas for a certain time, they can be directly pulled out through the activated carbon cover plate 17 for replacement and drying. When the ultraviolet lamp tubes 25 are damaged and need to be repaired and replaced, they can be directly pulled out through the lamp socket cover plate 23 for repair and replacement, avoiding the need to disassemble the entire purification device for replacement when the waste gas purification device needs to be replaced during long-term waste gas purification, and the replacement time is too long.
