The invention relates to a high-temperature pyrolysis device for organic waste gas, which comprises a casing body, a quartz tube, zinc oxide honeycomb ceramics and a magnetron; the casing body is provided with an organic waste gas inlet and an organic waste gas outlet; the quartz tube is installed in the casing In the box, one end of the quartz tube is installed at the inlet of the organic waste gas, and the other end is installed at the outlet of the organic waste gas; zinc oxide honeycomb ceramics are filled inside the quartz tube to form a microwave high-temperature reaction bed; the magnetron is installed in the shell box The outside is used for radiant heating of zinc oxide honeycomb ceramics; the inside of the shell box forms a resonant cavity. The present invention applies the characteristics of four-needle nano-ZnOw, which can quickly heat up and generate heat under the action of microwaves, to the field of high-temperature purification of organic waste gas. By adjusting the power of microwaves, the temperature of waste gas entering the device is controlled, and the organic waste gas undergoes high-temperature pyrolysis reaction in a high-temperature environment. In order to achieve the purpose of exhaust gas purification, the device has high exhaust gas decomposition rate, fast heating rate and accurate and controllable 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...
