Abstract
The invention provides a method and a device for removing volatile organic compounds by photo-production ozone catalytic oxidation. The device consists of a draught fan, a shell, a filter layer, an ultraviolet lamp and a catalyst, wherein the ultraviolet lamp and the catalyst form core components of the device. The purifying principle is as follows: ozone is generated by oxygen under an ultraviolet light effect, oxidized free radicals are generated by ozone under the ultraviolet light effect, the volatile organic compounds are converted into carbon dioxide and water under the effect of ozone and oxidized free radicals, unutilized ozone is further converted into oxidized free radicals under the catalyst effect, the volatile organic compounds are further degraded, and finally the discharging concentrations of the volatile organic compounds and ozone can achieve the discharging requirement. The method and the device can be applied to purification of industrial waste gas containing the volatile organic compounds and indoor air.

Technical field
The present invention relates to field of environmental technology, particularly a kind of photoproduction catalytic ozonation removes the method for volatile organic matter and application of installation in the waste gas purification process containing volatile organic matter, can be used for industrial waste gas and indoor air purification.
Background technology
Volatile organic matter (VOCs) is as component comparatively active in air, and it is not only directly detrimental to health, and also can form the secondary pollution such as photochemical fog and Organic aerosol in an atmosphere, become PM
2.5important as precursors thing.Meanwhile, VOCs or room air major pollutants.Therefore, the purification techniques of research and development VOCs, the discharge reducing VOCs contributes to environmental protect air quality and ensures health, is also the active demand of Sustainable Socioeconomic Development.
At present, the technology purified treatment such as absorption, burning or catalytic combustion, photochemical catalytic oxidation, plasma decomposes and biological treatment can be adopted the VOCs in industrial waste gas, yet there are no photoproduction catalytic ozonation process industrial waste gas VOCs technology.
In addition, indoor air cleaner is of a great variety, but most clarifier product exists inherent shortcoming.Filtering type clarifier can only remove particle, can not eliminate gaseous volatile organic matter.There is saturated phenomenon in adsorption cleaning device, needs frequently to change adsorbent.Photocatalysis technology is applied to indoor air purification, and because light utilization efficiency is low, purification efficiency is not high.Utilize photoproduction catalytic ozonation technology can significantly improve room air VOCs clearance.
The present invention proposes method and device that a kind of photoproduction catalytic ozonation removes VOCs, oxygen is utilized to produce ozone under action of ultraviolet light, ozone produces oxidative free radical under action of ultraviolet light, VOCs is converted into carbon dioxide and water under ozone and oxidative free radical effect, the ozone do not utilized is further converted to oxidative free radical under catalyst action, continue degraded VOCs, the exit concentration of final VOCs and ozone all reaches emission request.
