Background
The light oxygen clarification plant can be used for the processing of VOCs organic waste gas, and the core processing apparatus is usually several exhaust-gas treatment submodule that connects gradually in series, and every submodule piece is generally UV light oxygen lamp matrix, and the photocatalyst board of back complex. The UV light oxygen lamp has strong radiation, and mainly has the functions of cracking organic substances in the waste gas when the waste gas passes through the UV light oxygen lamp and decomposing the organic substances into harmless carbon dioxide and water; the photocatalyst plate amplifies the light source effect and can improve the purification efficiency.
The current photo-oxygen purification equipment generally has the following problems:
firstly, as can be seen from fig. 1-2 (fig. 1 is a top-view transverse sectional view of a vertical photo-oxygen purification device, and fig. 2 is a vertical longitudinal sectional view of a horizontal photo-oxygen purification device), the central position of every adjacent four photo-oxygen lamps (two of two adjacent photo-oxygen lamp groups) is a rectangular lattice structure, and the configuration structure is such that the effective illumination radiation area of the UV photo-oxygen lamps is smaller under the condition of a certain total power of the lamp tubes, which results in a smaller effective ventilation cross-sectional area of the device, and because the maximum effective ventilation air speed of the device is a certain value, the maximum effective ventilation volume of the device is smaller.
The second, UV photo-oxygen lamp matrix and the subsequent purification combination configuration of the cooperating photo-catalyst plate are usually simpler and lack of measures to improve the exhaust gas flow mixing sufficiently to improve the exhaust gas treatment efficiency. Some UV photo-oxidation devices are configured with similar measures, but have some defects, for example, chinese patent application No. 201720078917.2 discloses a high efficiency photo-oxidation catalytic device, the flow guide grid includes a grid and a plurality of flow guide vanes uniformly welded on the grid; the installation directions of the flow guide grids in the two adjacent groups of photo-oxidation catalytic units are opposite, and the design ensures that air flow is uniformly mixed, so that the photo-oxidation catalytic efficiency is improved; it has some problems: the central position of every adjacent distributed guide vane is a rectangular lattice structure, the positions of the guide vanes on every row and column are consistent, and the guide vanes are strung in the advancing direction of the exhaust gas flow, so that (1) when the width of the vanes is small, small local vortex gas flow is easy to appear, but because the periphery of the distributed vanes is a neutral gear, the resistance is small, most of the main exhaust gas flow is easy to escape and pass through the neutral gear between the rows and columns of the adjacent vanes, namely the neutral gear at the peripheral part outside the vane columns, and the effect is not ideal; (2) when the width of the blade is large, when the waste gas flows through, the vortex is stronger only at the position of the blade which is contacted with the blade firstly, and then the vortex effect is weakened step by step due to the layer blocking of the blade string at the same height behind the blade in the flowing direction of the gas flow, so that the effect is not ideal; (3) when the blade width is medium or equal, above-mentioned two problems also can the different degree exist, can not compromise, and partial air current directly escapes, passes through from the neutral gear outside the blade easily, and partial air current can be in the flow direction, through the layer upon layer barrier effect of blade cluster, and the vortex effect weakens step by step, and the effect is less than ideal.
