Most deodorizing and deodorizing devices are realized by ultraviolet photolysis box, so are there any specific parameters for the number of ultraviolet tubes in photolysis box? Is the more the better?

Before answering the question, let's understand the working principle of ultraviolet photolysis:

It uses high-intensity ultraviolet lamp to produce a certain amount of ozone, and then oxidizes and decomposes the malodorous waste gas into harmless gas. It is equivalent to a high-energy ozone machine, and the concentration of ozone discharged should be between 1mg/m3 and 10mg/m3. If it exceeds this concentration, the print shop will have a certain fishy smell and choking smell. After the waste gas enters the ultraviolet photolysis box, the residence time is only about 1-3 seconds, and the ozone oxidation generated by the waste gas is still completed in the subsequent pipeline. Therefore, the number of ultraviolet photolysis tubes should be controlled so that excess ozone cannot be discharged. So how many lamps do you need? Usually, the residence time and the area of air used are calculated. 2 thousand air volume is photolyzed by UV, and the residence time is 1 s, and the number of lamps per square meter is 14, which is more suitable.
