Printing ink peculiar smell, exhaust gas is very thick, what method to deal with?
Ultraviolet photolysis of ozone oxidation technology is a new type of exhaust gas treatment technology, its basic principle: gas hand in high-energy ultraviolet irradiation, the volatile organic compounds (VOCs) chemical bond ring opening and fracture and other reaction (photochemical reaction), degradation into CO2, H2O and other low molecular weight compounds;
By taking paint exhaust fan, the paint mist filter after purification, fine particles of dust, paint waste solidification and a small amount of organic exhaust particles were filtered to intercept, ensure that the dust particles in the waste gas are mostly intercept removal, exhaust gas re enters the pretreatment, enter the ultraviolet cold combustion deodorization device, with high energy ultraviolet light pyrolysis / ozone oxidation treatment, the final discharge to the atmosphere through the pipeline.
On the one hand, using oxygen to generate ozone high-energy ultraviolet irradiation in air, ozone ultraviolet absorption of oxygen free radicals and oxygen, oxygen free radicals and the water vapor in the air generate hydroxyl radicals, an oxidant, and alcohol, aldehyde, carboxylic acid and other organic waste, completely oxidized into water, carbon dioxide and other inorganic. In addition, ozone without UV absorption is also a strong oxidant, which is oxidized to some inorganic substances such as water and carbon dioxide after contact with some organic wastes.
