Description

technical field [0001] The invention relates to a photocatalytic device, in particular to a photocatalytic device with an online automatic cleaning function. Background technique [0002] Organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. In the prior art, various methods and principles such as activated carbon adsorption treatment method and acid-base neutralization method are widely used to treat organic waste gas. However, the equipment required for the activated carbon adsorption treatment method is simple and the investment is small, but the activated carbon is replaced frequently, which increases the work procedures such as loading, unloading, transportation, and replacement, which leads to increased costs and secondary pollution; the acid-base neutralization method generally uses physical absorption. The exhaust gas is introduced into the absorption liquid for purificatio...

AI Technical Summary

Problems solved by technology

The traditional cleaning method generally uses manual shutdown for cleaning. This cleaning method is not only very inconvenient, time-consuming and laborious, and the cleaning cycle is longer. Washing, cleaning efficiency is low, grease / dust dirt cleaning is not thorough enough

In addition, due to the long interval between each cleaning cycle of traditional photocatalytic equipment, the photocatalytic equipment is already full of grease and dust during each cleaning, which further increases the difficulty of cleaning

In this case, it is generally necessary to thoroughly clean the photocatalytic equipment, and it is necessary to frequently remove the ultraviolet lamp from the photocatalytic equipment. During the process of removing the ultraviolet lamp, it is very easy to cause the contact to break, thereby greatly shortening the The service life of the ultraviolet lamp increases the use and maintenance cost of photocatalytic equipment
