It is miscellaneous, predominantly some volatile sour gas and organic gas, such as: HCl, acetic acid, methanol, ethyl alcohol, n-hexane, acetone
Deng.In view of the very low complicated component of concentration, recycling economic benefit is low, is suitble to destructive decomposition.
Many exhaust-gas treatments services commercial city is handled using activated carbon adsorption at present, but due to the work after adsorption saturation
There is still a need for environmental protection treatments for property charcoal, not can solve real environmental problem.Therefore, it is necessary to one kind can prolong for low concentration gas
The technique of long acting charcoal service life.
Summary of the invention
The purpose of the present invention is to provide a kind of for examining the technique of testing laboratory's exhaust-gas treatment, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the invention provides the following technical scheme:
It is a kind of for examining the technique of testing laboratory's exhaust-gas treatment, including oxygenolysis section, sour gas absorbing reaction section and
Activated carbon adsorption section, the sour gas absorbing reaction section include solid basic material, and the one of sour gas absorbing reaction section
Side is connected with activated carbon adsorption section, and exhaust gas is through peroxide decomposition section, sour gas absorbing reaction section, activated carbon adsorption section heel row
Out.
As a further solution of the present invention: the oxygenolysis section includes that ozone oxidation and photooxidation are decomposed.
As further scheme of the invention: it includes UV oxygenolysis and photochemical catalytic oxidation point that the photooxidation, which is decomposed,
Solution.
