Mark pollutant the problems such as there are incomplete mineralisings.
Dual wavelength vacuum ultraviolet photocatalysis treatment industrial waste gas based on symmetrical ditrysian type structure according to the present invention
Method.Compared to common ultraviolet catalytic technology, having used vacuum ultraviolet i.e. wavelength is the ultraviolet light of 185nm, vacuum ultraviolet
Other than the performance with common ultraviolet, can also by air oxygen and steam transforming at a large amount of strong oxidizing properties activity
Group (HO2, O, OH isoreactivity free radical), while the ozone with strong oxidizing property is generated, promote target contaminant point
Sub-key aoxidizes scission of link by high concentration active group under the conditions of lower energy input, and the small molecule that formation is easier to oxidation removal is organic
Object, and target contaminant is mineralized thoroughly using the active catalyst component (titanium, manganese) of vacuum ultraviolet irradiation area.This method tool
There are specific innovative, practicability and economy.
Summary of the invention
In order to overcome the shortcomings of the prior art, have for industrial gaseous pollutant, especially atm number, low concentration
Machine exhaust gas (benzene homologues, esters) and odorant (H2S、NH3, thioether, mercaptan and organic amine) efficient removal, the present invention mentions
A kind of device and method of symmetrical ditrysian type ultraviolet catalytic processing industrial waste gas is supplied.
The present invention realizes vacuum ultraviolet photodestruciton, photocatalysis, a variety of industrial gas of catalytic ozonation synergistic purification removal
The integrated design method of state pollutant.Wherein, the vacuum-ultraviolet light of symmetrical ditrysian type structure realizes the abundant benefit of ultraviolet light
With the advantages that the making full use of and remove of ozone that generates in, reaction, while also there is replacement easy to install, be easy to use and safeguard etc.
