Problems solved by technology

[0003] The existing technology usually adopts three treatment methods for VOCs: 1. Activated carbon adsorption: the disadvantage is that the activated carbon is easily saturated, and the humidity is high and has no adsorption effect, so it needs to be replaced frequently; 2. Plasma UV photocatalytic treatment: the disadvantage is that UV photolysis requires high-energy ultraviolet rays The energy of the photons produced by the high-energy ultraviolet rays emitted by the lamp must be greater than the molecular bonding energy of the odorous gas molecules in order to crack the VOCs gas molecules. If there are attachments on the surface of the lamp, it will be invalid; the light decay of the lamp is serious; Low efficiency, treatment efficiency: 20%-30%; 3. Combustion treatment: The disadvantages are high price, large floor area, high risk of explosion, daily inspection by firefighters, and if burning gas, natural gas storage capacity and storage qualification are required. If electric heating is required, high electricity bills are required

Abstract

The invention provides an air cabinet system for decomposing VOCs (volatile organic compounds) by a vertical lathe catalyst. The system comprises a washing spraying device, a dehumidification drying device, a high-voltage electrostatic device, a rear tretament device, a rectifying air pipe and a reducing air pipe, wherein the front end of the washing spraying device is connected with the rectifying air pipe, the rear end of the washing spraying device is connected with the dehumidification drying device, the high-voltage electrostatic device is mounted behind the dehumidification drying device, the rear treatment device is mounted behind the high-voltage electrostatic device, an HEPA filter layer, vertical lathe catalyst reactor sets and a variable-frequency fan are sequentially arranged in the rear treatment device from left to right, and the rear end of the variable-frequency fan is connected with the reducing air pipe. VOCs in the air can be thoroughly decomposed into water molecules and CO2 which cause no pollution and are discharged into the air when passing through the air cabinet system for decomposing the VOCs by the vertical lathe catalyst, so that pollution is reduced andthe environment is protected.

Description

technical field [0001] The invention belongs to the field of wind cabinet systems, and in particular relates to a wind cabinet system for decomposing VOCs by catalysts in vertical vehicles. Background technique [0002] Volatile organic compounds, namely volatile organic compounds, referred to as VOCs. The total emission of VOCs exceeds sulfur dioxide and nitrogen oxides, and it is one of the important precursors for the formation of PM2.5 and ozone, which is very harmful to human health. However, unlike sulfur dioxide and nitrogen oxides, in most cases VOCs come from unorganized industrial emissions, that is, irregular emissions that do not pass through the exhaust stack. Industrial waste gas contains not only VOCs that pollute the atmosphere, but also other inorganic and organic pollutants. There are many specific types of VOCs, including benzene, toluene, xylene, styrene, trichlorethylene, etc., coupled with unorganized emission methods, making VOCs governance more comp...
