Description

A kind of TiO 2Photolysis purification device

Technical field

The treating apparatus of the utility model design foul gas or industrial smoke, a kind of light catalytic purifying device that is applied to foul gas or industrial smoke of more specifically saying so.

Background technology

Foul gas pollutes and is meant that all stimulate olfactory organ to cause the gaseous matter that people are unhappy and damage living environment.The odor strength of odorant is with increasing of attempting and strengthen, show according to numerous research datas, it is to be directly proportional with the quantity of stimulus contrast number of odorant to people's sense of smell that stench is given people's sensation amount (being stench intensity), and relation meets the Weber-Fechner law between the two:

I＝K+logC+a

I in the formula: the people is to the sensation amount of sense of smell, odor strength

K: constant, different odorant value differences

C: odorant concentration

A: constant, different odorant value differences

Removed 90% even from formula, know foul gas, but the people has only reduced half to the sensation amount (odor strength) of sense of smell, and this technical difficulty that has just determined foul gas to handle is big, shows according to the study, compare with handling other waste gas, handle foul gas and want difficult hundreds and thousands of times.

Foul gas is generally acknowledged by countries in the world that as a kind of typical environmental hazard many developed countries are studied it as a kind of single-row public hazards, and control is implemented in special legislation.Abroad the improvement work of odor pollution is also carried out early, in Japanese and American-European a plurality of industrial circles, adopted as technology such as fixed-bed type active carbon adsorption deodorizations existing certain historical.

In recent years, China also begins to pay attention to the monitoring and the control of foul gas and obtains certain effect, adopts traditional technical method in China mostly in to foul gas improvement technology, and all there is certain shortcoming in these technology.China has worked out the discharge standard (GB1455-93) and the supporting analytical method of part malodorous compound, one of prevention on odor pollution target will reach odorant (ammonia, trimethylamine, mineralising hydrogen, first sulphur hydrogen, methyl mercaptan, methyl sulfide, methyl disulfide, two mineralising carbon and the styrene etc.) discharge standard of GB14554-93 regulation exactly, final purpose is to eliminate stench, creates the environment of an odorless.

The technical method of administering at present foul gas both at home and abroad has: 1, firing method; 2, catalytic oxidation; 3, ozone deodorization process; 4, active carbon adsorption; 5, soup spray process; 6, biological deodorizing method etc.Though they obtain certain achievement on foul gas is handled, exist equipment investment big in varying degrees; Operational management cost height; Handle narrow-minded; It is big to take up room; Handle not thorough; Cause secondary pollution; Job insecurity; Deodorising effect is not high; Shortcomings such as energy consumption is big.
