Problems solved by technology

As a processing technology widely used in industry, the painting process is often accompanied by a large amount of waste gas containing various impurities. According to the different paint materials used for painting, the waste gas often includes grease, carbon particles, inorganic substances, etc. Impurities, difficult to purify, after long-term use, impurities accumulate in large quantities
[0003] At present, the paint spraying workshops on the market usually treat the waste gas generated during the painting process by cooling, water cooling and simple filtration. After the treatment, there are still a large number of small particles of impurities and toxic gases in the waste gas, which cannot meet the environmental protection requirements.

Embodiment 1

[0039] refer to figure 1 , an environment-friendly air purification device, used to treat the waste gas produced in the painting workshop, including a main tower 1, the main tower 1 is a hollow structure, the side of the main tower 1 is provided with an air inlet pipe 2, and the air inlet pipe 2 is connected to the main tower 1. The exhaust gas enters from the air inlet pipe 2 and is discharged from the top of the main tower 1.

[0040] refer to figure 2 and image 3 , some water curtain devices 3 are arranged in the air inlet pipe 2, and the water curtain devices 3 are used to produce a water curtain. slit 321, the nozzle 32 is used to connect with the water pipe, and the water pipe passes water into the nozzle 32 and sprays out from the nozzle 321 to form a water curtain. When the exhaust gas passes through, the water curtain blocks and dissolves the large particles of impurities in the exhaust gas Remove water-soluble impurities and toxic gases such as ammonia nitrogen ...

Embodiment 2

[0052] The difference with embodiment 1 is the preparation of anti-adhesion coating, and its preparation method is as follows:

[0053] Take the following components by weight for later use: 32 parts of epoxy resin, 25 parts of polytetrafluoroethylene, 16 parts of polyvinyl chloride, 64 parts of acetone, 22 parts of ether, 6 parts of ethyl acetate, and 8 parts of polymethacrylate 5 parts, 5 parts of hydroxyalkyl methacrylate, 6 parts of ethyl methacrylate;

[0054] S1. Prepare the first prefabricated solution: add epoxy resin, polytetrafluoroethylene, and polyvinyl chloride into acetone to dissolve, stir evenly, heat the overall temperature to 58° C., and heat-preserve for 25 min to obtain the first prefabricated solution;

[0055] S2. Preparation of the second prefabricated solution: mix ethyl acetate, polymethacrylate, hydroxyalkyl methacrylate, ethyl methacrylate and diethyl ether evenly, heat the overall temperature to 44°C, heat preservation for 35min, Obtain the second ...

Description

technical field [0001] The invention relates to the field of air purification, in particular to an environment-friendly air purification device. Background technique [0002] As society pays more and more attention to environmental protection issues, domestic waste gas and industrial waste gas discharged into the atmosphere must meet strict emission standards before they can be discharged. As a processing technology widely used in industry, the painting process is often accompanied by a large amount of waste gas containing various impurities. According to the different paint materials used for painting, the waste gas often includes grease, carbon particles, inorganic substances, etc. Impurities are difficult to purify, and after long-term use, impurities accumulate in large quantities. [0003] At present, paint spraying workshops on the market usually treat the waste gas generated during the painting process by cooling, water cooling and simple filtration. After the treatm...
