A kind of ultraviolet catalytic oxidation deodorizing device

Technical field

This utility model belongs to a kind of odor removal, relates in particular to a kind of ultraviolet catalytic oxidation deodorizing device.

Background technology

Stench is a kind of form of atmospheric pollution, the same sensation public hazards that all belong to noise, and noise directly acts on people's audition, and stench directly acts on people's olfactory sensation, causes harm to the people, gently then does not feel like oneself, heavy then poisoning.Stench has become a kind of in seven kinds of typical public hazards in the world today (atmospheric pollution, water pollution, soil pollution, sound pollution, vibration, land subsidence, stench).China had formulated " odorant pollutant discharge standard " (GB14554-93) in 1993.Standard is pointed out: odorant pollutant is meant that all stimulate organum olfactorium to cause the gaseous matter that people are unhappy and damage living environment.And specifically list the discharge standard of 9 kinds of odorant pollutants (hydrogen sulfide, methanthiol, methyl sulfide, dimethyl disulfide, Carbon bisulfide, ammonia, trimethylamine, styrene, odor concentration).Various countries efforts at environmental protection person was through research and the engineering practice to odor treatment in more than 20 years, developed some more sophisticated odor treatment technology (comprising chemical absorption method, bio-trickling method, masking method, plant extraction liquid catalytic oxidation, absorption method or catalytic type active carbon adsorption, firing method, soil absorption process, ozone deodorization process, low-temperature plasma method, energetic ion method, active oxygen method etc.) but existing technology generally have take up room big, resistance is big, energy consumption is high, equipment investment is high, have secondary pollution problems, and treatment effect waits to improve.Stench is directly proportional for people's sensation amount (being stench intensity) with the logarithm of odorant to the quantity of stimulus of people's olfactory sensation, even odorant removes 90%, but the odor strength that people's olfactory sensation is experienced only reduces less than half.Therefore, the difficulty of odor treatment is very big.

Summary of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of odor removal can utilize ultraviolet energy to greatest extent, by UV ozone oxidation, and the multiplexing effect of nano titanium oxide ultraviolet catalytic oxidation, to the method that foul gas purifies, reach deodorization and sterilization dual purpose.
