Embodiment 1

[0042] Refer to attached Figure 4 , 5 , a simple device for photocatalytic treatment of organic waste gas, the device is mainly composed of air outlet 1, hollow quartz glass sleeve 2, ultraviolet lamp 3, movable cover plate 4, support feet 5, organic waste gas inlet 6, slot 7, box body 8. The fixed bed type load is composed of TiO2 foam nickel mesh 9 and the temperature and humidity meter installation port 10. The box body 8 is divided into three layers, and the adjacent two layers are supported by the slot 7 provided on the inner wall of the box (not shown) to support the fixed bed type load. The TiO2 foamed nickel mesh is divided into 9 parts; the left and right sides of the box body 8 have holes crossing to install the hollow quartz glass casing 2, and the ultraviolet lamp tube 3 is placed in the hollow quartz glass casing 2. The rear side of the box body 8 is a detachable cover plate 4, and an elastic gasket (not shown) is arranged between the cover plate 4 and the box b...

Abstract

The invention discloses a simple device for photocatalytically treating organic waste gases. The device comprises a hermetic box body, wherein the box body is divided into three layers, and every two adjacent layers are divided by a photocatalytic material which is supported and fixed by slots formed in internal walls of the box body; the left and right sides of the box body are perforated, hollow quartz glass sleeves are mounted in a traversing manner, and ultraviolet lamp tubes are placed in the quartz glass sleeves; the rear side of the box body is a detachable cover plate, and an elastic sealing gasket is arranged between the cover plate and the box body and is sealed and fixed by a flange; gas inlets are formed in the lower end of the box body, and gas outlets are formed in the upper end of the box body; the upper part of the box body is provided with a thermometer and hygrometer mounting port; and peripheries of inner sides of the box body are attached with reflecting tin foil which is free of ultraviolet influence. According to the simple device for photocatalytically treating the organic waste gases, disclosed by the invention, the structure is simple, the mounting is convenient, and a photocatalytic reaction can be effectively carried out; and the device can be reused, so that the cost is low.

Description

technical field [0001] The invention relates to the field of organic waste gas treatment, in particular to a photocatalytic reactor. Background technique [0002] Atmospheric pollution is one of the most prominent environmental problems at present. After the pollution control of SO2 and NOx produced by fuel combustion has been given full attention, the emission control of some volatile organic compounds (VOCs) has become an important issue for improving the quality of regional air environment. way. In May 2010, the "Guiding Opinions on Promoting Joint Prevention and Control of Air Pollution to Improve Regional Air Quality" forwarded by the State Council listed VOCs, together with SO2, NOx and particulate matter, as four key pollutants for air pollution control for the first time. [0003] The technologies for controlling VOCs pollution mainly include absorption method, adsorption method, condensation method, and combustion method. These technologies generally have problems ...
