Catalytic high-pressure decomposition reactor for treating industrial waste gas

Abstract

The invention discloses a catalytic high-pressure decomposition reactor for treating industrial waste gas. A plurality of nickel-palladium alloy foils uniformly float in the reactor, the top of the reactor is provided with a set of gas compression piston, and the gas compression piston is connected to a hydraulic compression device at the top end of the reactor through a telescopic transmission rod. According to the catalytic high-pressure decomposition reactor for treating the industrial waste gas, the characteristic that a benzene ring in an aromatic hydrocarbon molecule is easily catalyzedby a metal surface and then decomposed in a state of high internal energy is utilized, exhaust gas containing an aromatic hydrocarbon compound is subjected to volume compression at first to increase the internal energy of the exhaust gas, then the exhaust gas is in contact with the surface of nickel-palladium alloy, under the condition that ultraviolet rays continuously irradiate and excite the nickel-palladium alloy, the conjugated chemical bonds of the benzene ring in the aromatic hydrocarbon molecule can break on the surface of the nickel-palladium alloy, the aromatic hydrocarbon molecule can be gradually cracked to generate inorganic molecules such as H2O and CO2, and therefore, a purpose of removing aromatic hydrocarbon compounds in the exhaust gas is achieved.

Description

technical field [0001] The invention relates to a catalytic high-pressure decomposition reactor for treating industrial waste gas, which belongs to the field of waste gas treatment in environmental protection. Background technique [0002] Air pollution is one of the most prominent environmental problems in my country at present, and volatile organic waste gas is an important source of air pollutants. With the rapid development of my country's petrochemical industry, the volatile organic waste gas discharged into the atmosphere during the production process is also increasing. These pollutants mainly include aromatic hydrocarbon compounds (benzene series), aldehydes and ketones, halogenated hydrocarbons, Alcohols, etc. Among them, the emission of aromatic hydrocarbons is relatively large, and its harm to the ecological environment and human health is relatively prominent. Therefore, the purification treatment of aromatic hydrocarbons has attracted more and more attention. ...

AI Technical Summary

Problems solved by technology

[0016] At present, the aromatic hydrocarbon waste gas treatment methods commonly used in my country generally have disadvantages such as large initial investment, high operation and maintenance costs, and complicated technology, and the treatment effect is difficult to meet the increasingly stringent emission requirements.
