Abstract

The invention provides a standardized discharge treatment device for high concentration VOCs tail gas based on condensing catalytic oxidation, belongs to the technical field of organic exhaust gas treatment, and in particular relates to a recovery government device for high concentration VOCs tail gas discharged in processes or reaction kettle processes such as petroleum chemical engineering, finechemical engineering, pharmaceutical manufacturing and resin production. The device is formed by a condensing system and a catalytic oxidization system as well as pipelines and valves connected between the systems. The device can avoid problems and risks in evaporative condensation, solves the problem that organic exhaust gas which is condensed independently is hard to discharge in a standardizedmanner, and also can solve the problem that the operating energy consumption is high in the exhaust gas treatment process by a combined process effectively. The device is efficient, energy-saving, reliable and good in economical benefit, and the treatment efficiency can reach over 99.9%.

Description

technical field [0001] The invention relates to the technical field of organic waste gas treatment, in particular to a high-concentration VOCs tail gas discharge treatment device based on condensation catalytic oxidation, which is especially suitable for petrochemical, fine chemical, pharmaceutical manufacturing, resin production and other processes or the discharge of reactors. High-concentration VOCs tail gas recovery and treatment. Background technique [0002] The tail gas discharged from petrochemical, fine chemical, pharmaceutical and resin production industries has high concentration and complex components, mainly volatile organic compounds (Volatile Organic Compounds, referred to as VOCs), most of which are toxic, harmful and have certain carcinogenicity. In 2015, the Ministry of Environmental Protection issued the "Petrochemical Industry Pollutant Discharge Standard (GB31571-2015)" and "Petroleum Refining Industry Pollutant Discharge Standard (GB31570-2015)", which ...
