Abstract
Description
Technical Field
[0001] This utility model relates to the field of VOC degradation equipment technology, specifically a high-efficiency photocatalytic device for VOC degradation. Background Technology
[0002] Volatile organic compounds (VOCs) are significant pollutants in industrial waste gases, posing a serious threat to the environment and human health. Photocatalytic oxidation technology, due to its high efficiency, low energy consumption, and lack of secondary pollution, has become one of the mainstream methods for VOC degradation. Photocatalytic ionization purifiers, as typical photocatalytic devices, use ultraviolet light to excite catalysts (such as TiO2) to generate highly oxidizing active substances (such as ·OH and O2). - ( ), which decomposes VOCs into harmless substances such as CO2 and H2O.
[0003] However, traditional photo-ion air purifiers have the following problems in practical applications: 1. Single airflow path: Existing devices usually adopt a straight airflow design, which results in a short contact time between pollutants and catalysts, causing some VOCs to be discharged before being fully degraded, thus limiting the purification efficiency; 2. Additional treatment equipment required: To meet emission standards, multiple purification units often need to be connected in series, which increases system complexity and energy consumption.
[0004] To this end, we propose a high-efficiency photocatalytic device for VOC degradation. Utility Model Content
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-efficiency photocatalytic device for VOC degradation. A baffle plate is installed in the reaction chamber to force air to rotate and flow, extending the residence time in the catalytic zone, thereby improving the quality of waste gas treatment and reducing noise. This effectively solves the problems in the background technology.
[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-efficiency photocatalytic device for VOC degradation, comprising a mounting plate, wherein a photohydrogen ion purifier is fixedly mounted on the upper outer surface of the mounting plate, and the photohydrogen ion purifier is provided with a protective guide hood, wherein the protective guide hood comprises a protective cover, an air inlet, an air outlet, a baffle plate and an arc-shaped chamfered block, the protective cover is fixed to the upper outer surface of the mounting plate, and the protective cover covers the outside of the photohydrogen ion purifier.
[0007] Preferably, the baffle is fixed on the left and right sides of the inner cavity of the protective cover, and the arc-shaped chamfered block is fixed between one end of the upper outer surface of the baffle and the inner wall of the protective cover.
[0008] Preferably, the air inlet is fixed to the upper part of the outer surface of one side of the protective cover, and the air outlet is installed on the lower part of the outer surface of the other side of the protective cover.
[0009] Preferably, the protective cover consists of an inner shell and an outer shell, and there is a cavity layer between the outer wall of the inner shell and the inner wall of the outer shell.
[0010] Preferably, the cavity layer is filled with noise-reducing cotton, and the noise-reducing cotton is made of rock wool.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-efficiency photocatalytic device for VOC degradation, which has the following beneficial effects: 1. This high-efficiency photocatalytic device for VOC degradation uses baffles and chamfered blocks inside the protective cover to force the airflow to form swirling or turbulent flow, thereby extending the residence time of pollutants in the catalytic zone of the photo-hydrogen ion purifier, allowing VOCs to fully contact the photocatalyst and improving degradation efficiency.
