Organic waste gas high-temperature pyrolysis device

Abstract

The invention relates to an organic waste gas high-temperature pyrolysis device. The organic waste gas high-temperature pyrolysis device comprises a shell box body, a quartz tube, a zinc oxide honeycomb ceramic and a magnetron; the shell box body is provided with an organic waste gas inlet and an organic waste gas outlet; the quartz tube is arranged in the shell box body, one end of the quartz tube is arranged at the organic waste gas inlet, and the other end of the quartz tube is arranged at the organic waste gas outlet; the quartz tube is filled with the zinc oxide honeycomb ceramic to forma microwave high-temperature reaction bed; the magnetron is arranged outside the shell box body and used for carrying out radiation heating on the zinc oxide honeycomb ceramic; and a resonant cavity is formed inside the shell box body. According to the invention, the characteristic that tetrapod-shaped nano ZnOw can be rapidly heated under the action of microwaves is applied to the field of high-temperature purification of organic waste gas, the temperature of the waste gas entering the device is controlled by adjusting the power of the microwaves, and the organic waste gas is subjected to high-temperature pyrolysis reaction in a high-temperature environment so as to achieve a purpose of waste gas purification. The device is high in waste gas decomposition rate, high in heating rate and accurate and controllable in temperature.

Description

technical field [0001] The invention relates to the technical field of organic waste gas purification, in particular to a high-temperature pyrolysis device for organic waste gas. Background technique [0002] Volatile organic compounds (volatile organic compounds, VOCs) are the main components of industrial organic waste gas, usually refer to a class of organic chemical substances that exist in the air in the form of steam at normal temperature and Alkanes, aromatic hydrocarbons, olefins, oxygen-containing hydrocarbons and halogenated hydrocarbons, such as benzene, toluene, formaldehyde, methylene chloride and ethyl acetate, etc. VOCs are mostly toxic substances, and at the same time, volatile organic compounds are the main precursor substances that constitute inhalable particulate matter. If the emission of organic waste gas in the air increases, it will not only pollute the environment, form photochemical smog, and destroy the ozone layer, but also cause serious damage to...
