Problems solved by technology
[0002] At present, the main components used as paint solvents are toluene or xylene, etc., but toluene or xylene is volatile and has an unpleasant taste, and has an irritating effect on the eyes and upper respiratory tract. Obvious irritation symptoms of the respiratory tract, dizziness, convulsions or coma in severe cases, long-term exposure can cause neurasthenia, chapped skin, and even cause cancer or damage and failure of certain organs
People spray the material after diluting the paint with a solvent containing toluene or xylene. Generally, the toluene or xylene in the paint is allowed to volatilize. Although people have taken certain protective measures, the health of the operators is still subject to certain restrictions. damage; on the other hand, the degradation process of toluene or xylene volatilized into the air is slow, and the impact on the environment is long-term

Embodiment Construction
[0018] The automatic recovery method of volatile matter after spraying paint of the present invention is as figure 2 As shown, at first, the volatile gas in the painting workshop 1 is transported to the cooling device 4 through the pipeline 3 with the exhaust device 1-2, and a liquid collection bottle 5 is installed on the cooling device 4, and most of the volatile gas is in the elongated and spiral guide. In the trachea 14, it becomes liquid after meeting cold and injects in the liquid collecting bottle 5 .
[0019] After passing through the cooling device 4, a small part of the volatile gas left behind enters the filter device 6, and granular activated carbon 7 is arranged in the filter device 6, and the granular activated carbon 7 has a strong adsorption to volatile toluene and xylene effect. A heating device 8 is provided in the granular activated carbon 7 . The gas passing through the filter device 6 is detected by the toluene and xylene detector 10 installed on the ex...

The invention discloses a method for automatically recycling volatile substances produced after spray painting, relating to the field of air purification. By using the method, the problem that the volatile substances produced after spray painting affect the body health of an operator, environmental friendliness and the like at present is solved. The method for automatically recycling the painted volatile substances comprises the following steps of: cooling and recycling the volatile substances, and adsorbing the rest volatile substances by using active carbon, wherein the purified gas is exhausted to the air; and meanwhile, desorbing the active carbon, and cooling and recycling the volatile substances, wherein the desorbed active carbon can be continuously used. By using the method for automatically recycling the painted volatile substances, the operator is prevented from directly contacting the substances such as methylbenzene, dimethyl benzene and the like; and the method is energy-saving and environmentally-friendly.
Description
technical field [0001] The invention relates to an air purification method, in particular to a method for automatically recovering volatile substances after painting. Background technique [0002] At present, the main components used as paint solvents are toluene or xylene, etc., but toluene or xylene is volatile and has an unpleasant taste, and has an irritating effect on the eyes and upper respiratory tract. Obvious respiratory tract irritation, dizziness, convulsions or coma in severe cases, long-term exposure can cause neurasthenia, chapped skin, and even cause cancer or damage and failure of certain organs. People spray the material after diluting the paint with a solvent containing toluene or xylene. Generally, the toluene or xylene in the paint is allowed to volatilize. Although people have taken certain protective measures, the health of the operators is still subject to certain restrictions. On the other hand, the degradation process of toluene or xylene volatilize...
