Embodiment Construction

[0036] Such as figure 1 The shown purification system for removing VOC in industrial waste gas includes filter A1, induced draft fan 2, condenser A3, gas-liquid separator A4, iron-cobalt photocatalyst salinization effect dehalogenation reactor 5, adsorption tower A6, adsorption Tower B7, adsorption tower C8, PLC automatic control unit 9, VOC gas detector 10, steam generator 11, filter B12, air compressor 13, dryer 14, condenser B15, gas-liquid separator B16 and 17 sets of program control Valves V1~V17, etc. Among them, the industrial waste gas containing VOC enters the system through the gas pipeline, firstly filters out the acidic and alkaline gas components and particulate matter in the waste gas through the filter A1, and then provides kinetic energy for the waste gas through the induced draft fan 2 , the exhaust gas is sent to the condenser A3, where the temperature of the exhaust gas entering the adsorption tower is reduced to ensure the optimal adsorption temperature of ...

Abstract

The invention discloses a purifying system for removing VOC (Volatile Organic Compounds) out of industrial waste gas. The purifying system comprises a filter A, a fan, a condenser A, a gas-liquid separator A, an iron-cobalt photocatalyst salinization effect dehalogenation reactor, an absorbing tower A, an absorbing tower B, an absorbing tower C, a PLC automatic control unit, a VOC gas detector, a steam generator, a filter B, an air compressor, a drier, a condenser B, a gas-liquid separator B and 17 sets of program control valves. The purifying system disclosed by the invention has the advantages that the metal photocatalyst salinization effect is creatively applied to uniformly diffuse iron-cobalt metallic elementary fine powder in the waste gas, and under the irradiation of blue light with specific wavelength, halogenated hydrocarbon in the waste gas VOC can generate photocatalystic reaction with elementary iron and cobalt, wherein halogen atoms are compounded with iron and cobalt to produce macromolecular complex salt so as to finish dehalogenation treatment of VOC; after the VOC waste gas is treated by dehalogenation, the consumption for the absorbing efficiency of active carbon can be greatly reduced, so that the absorbing efficiency of the active carbon is obviously improved.

Description

technical field [0001] The invention relates to a system for purifying industrial waste gas VOC, which belongs to the field of waste gas treatment in environmental protection. Background technique [0002] VOC is the English abbreviation of Volatile Organic Compounds (Volatile Organic Compounds), which is the 2 、H 2 CO 3 , metal carbide, metal carbonate and ammonium carbonate, any carbon compound that participates in atmospheric photochemical reactions, including formaldehyde, ammonia, ethylene glycol, esters and other substances. When the VOC in the room or manufacturing site reaches a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, etc., and even cause convulsions and coma in severe cases. It will also damage the liver, kidneys, brain and nervous system, causing memory loss and other serious symptoms as a result of. Therefore, how to control VOC has been a subject of continuous research and development and exploration at home ...
