Embodiment Construction
[0010] The specific working process of the novel automobile paint booth using negative pressure and circulating air will be described in detail below in conjunction with the accompanying drawings.
[0011] Such as figure 1 , 2. When the paint booth is working, the temperature of the lower layer in the paint booth body 4 is relatively high, and the temperature of the upper layer is relatively low. The area is heated unevenly. After the hot air circulation diffusion and convection system 6 is set, under the action of the high temperature resistant blower fan 3, the relatively low temperature gas on the upper layer of the paint booth body 4 is evenly inhaled through the air suction hole 8 of the return air exhaust pipe 7, and then the air is sent to The air jet hole 10 of the air exhaust pipe 9 is re-sent into the paint booth body 4 from the bottom of the paint booth body 4, so that the originally unevenly cold and hot gas can be effectively mixed evenly, so that the temperature...

The invention belongs to the productive maintenance coating and air pollution control technical field. A novel automobile baking finish house by utilizing negative pressure and circulating air solves the problems that baking finish quality of each component is different due to uneven heating on the surface of an automobile in an existing automobile baking finish house and pollution due to waste gas escaping and direct discharging in the automobile baking finish house. The novel automobile baking finish house by utilizing negative pressure and circulating air is mainly composed of a baking finish body, a heating system, a control system, a lighting system, a safety system, a hot air circulating, diffusing and convection system and an air exhaust purification system. The hot air circulating, diffusing and convection system can effectively increase heating uniformity of baking finish components, and thus baking finish quality on the surface of the automobile is even and uniform. The air exhaust purification system can create a favorable negative pressure environment for the automobile baking finish house, and solves the escaping problem of the waste gas in the automobile baking finish house. Extracted waste gas is processed by an air purification device, and pollution problem caused by direct discharging of the waste gas can be effectively resolved.
Description
technical field [0001] The invention relates to a new type of automobile paint booth using negative pressure and circulating air, which can solve the pollution problem caused by the leakage of harmful exhaust gas and direct discharge in the paint booth, and can also increase the uniformity of the paint quality on the surface of the car, which belongs to the production maintenance coating And gas pollution control technology field, can be widely used in the automobile industry. Background technique [0002] In recent years, my country's automobile industry has developed rapidly, especially in the field of automobile production, maintenance and painting. Automobile paint booths have gradually emerged in every corner of the city. When the paint booths are working, they will produce a large amount of harmful exhaust gas, which seriously pollutes the surrounding environment and endangers people's health. [0003] When the existing automobile paint booth is in operation, the gas i...
