Abstract

The invention discloses a waste gas treatment module of photo-oxygen purification equipment. The waste gas treatment module comprises a box body and at least two columns of photo-oxygen lamp sets arranged in the box body in the waste gas flow advancing direction. All photo-oxygen lamps in each column of photo-oxygen lamp sets are arranged front and back in the width direction of the box body or arranged up and down in the height direction of the box body, at least two columns of photo-oxygen lamp sets are arranged in a staggered mode, and the distance between every two adjacent photo-oxygen lamps in the photo-oxygen lamp sets arranged in the staggered mode is larger than the maximum effective performance distance value of the photo-oxygen lamps. The distance between every two adjacent photo-oxygen lamps in each column of photo-oxygen lamp sets is any one of equal, partially unequal and totally unequal. The waste gas treatment module further comprises at least two columns of flow guide plate sets arranged in the box body in the waste gas flow advancing direction and photocatalyst plates arranged in the box body in the waste gas flow advancing direction. The waste gas treatment module can improve the maximum effective ventilation quantity of the equipment, increase the waste gas flow walking path, improve the waste gas flow mixing sufficiency degree and improve the treatment efficiency of the photo-oxygen purification equipment.

Description

technical field [0001] The invention relates to the field of waste gas treatment of photo-oxygen purification equipment, in particular to a waste gas treatment module of photo-oxygen purification equipment. Background technique [0002] Photo-oxygen purification equipment can be used for the treatment of VOCs organic waste gas. The core treatment device is usually several waste gas treatment sub-modules connected in series. Each sub-module is generally a matrix of UV photo-oxygen lamps and a photocatalyst plate that is matched afterwards. The UV light oxygen lamp has strong radiation, and its main function is to crack the organic matter in the waste gas when the waste gas passes through, and decompose it into harmless carbon dioxide and water; the photocatalyst plate amplifies the effect of the light source and can improve the purification efficiency. [0003] The current photo-oxygen purification equipment usually has the following problems: [0004] First, by Figure 1-Fi...

Problems solved by technology

[0005] Second, the purification combination configuration structure of the UV photo-oxygen lamp matrix and the subsequent photocatalyst plate is relatively simple, and there is a lack of measures to improve the exhaust gas flow to fully mix and improve the efficiency of exhaust gas treatment

Some UV photo-oxygen equipment is equipped with similar measures, but there are some defects. For example, the Chinese patent application number 201720078917.2 discloses a high-efficiency photo-oxygen catalytic device. Multiple guide vanes on the top of the photo-oxygen catalytic unit; the installation direction of the guide grilles in the adjacent two groups of photo-oxygen catalytic units is opposite. Although this design makes the air flow evenly mixed and improves the efficiency of photo-oxygen catalysis; but there are some problems: each phase The central position of the adjacent dispersed guide vanes is a rectangular lattice structure, the guide vanes are in the same position in each row and column, and they are clustered in the forward direction of the exhaust gas flow. In this way, (1) when the blade width is small, the small Local vortex airflow is easy to appear, but because the surrounding of the distributed blades is neutral, the resistance is relatively small, and most of the main exhaust gas flow is easier to escape from the gap between adjacent rows and columns of blades, that is, the gap around the outer periphery of the blade row. , the effect is not ideal; (2) When the width of the blade is large, when the exhaust gas flow passes through, the vortex is relatively strong only at the blade that first touches, and then the airflow in the direction of flow will be due to the blades at the same height behind The vortex effect is gradually weakened by the series of blocks, and the effect is not ideal; (3) When the width of the blade is medium, the above two problems will also exist to varying degrees, and it cannot be taken into account. After escaping and passing, part of the airflow will pass through the layer-by-layer blocking effect of the blade string in the direction of flow, and the vortex effect will gradually weaken, and the effect is not ideal.
