Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste gas treatment, in particular to a catalytic combustion furnace for organic waste gas. Background Art
[0002] Organic waste gas is a gaseous pollutant, mainly derived from chemical waste gas, fluorine-containing waste gas, gaseous hydrocarbons, odorous gases, etc. from various industries. Its components mainly include formaldehyde, toluene, xylene, acetone, butanone, non-methane total hydrocarbons, acetic acid, ethyl esters and other organic compounds. These organic waste gases are flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to handle. The organic waste gas catalytic combustion furnace is a device used to treat organic waste gas. Its core is to use catalysts to promote the oxidation reaction of combustible substances in organic waste gas at a lower temperature, thereby converting them into harmless carbon dioxide and water vapor.
[0003] A common catalytic combustion furnace for organic waste gas generally includes structures such as a pretreatment mechanism, a fan and a furnace body. When in use, the gas is first introduced into the pretreatment mechanism through the fan, and the dust impurities in the waste gas are filtered through the filtering structure inside the pretreatment mechanism and then discharged into the combustion furnace for catalytic combustion. However, in this method, the dust in the gas will quickly clog the filter screen when the waste gas is initially filtered, and since the filter screen is generally installed inside the box, the dust particles on its surface cannot be cleaned in time, which affects the quality of waste gas filtration, and further causes the subsequent catalytic combustion to fail to be completed with high quality, and cannot meet the working requirements of waste gas treatment. For this reason, an organic waste gas catalytic combustion furnace is proposed. Utility Model Content
