Methods for treating organic waste gas with catalytic combustion equipment
2021-10-16
Do you know how catalytic combustion deals with organic waste gas? Let Tangshan Lantian Aoyu Technology Co., Ltd. tell you
Catalytic combustion is a typical gas-solid phase catalytic reaction. Catalytic combustion reduces the activation energy of the reaction through the catalyst, enricheds the reaction molecules on the surface of the catalyst, improves the reaction rate, and enables flameless incineration to be carried out at a low ignition temperature of 200-300℃. It is oxidized and decomposed into CO2 and H2O, and emits a lot of heat.
Organic waste gas is a common pollutant in petrochemical, plastics, printing, coatings, paints and other occupations. Organic waste gas usually contains hydrocarbons, oxygen containing organic compounds, nitrogen, sulfur, halogen, phosphorus containing organic compounds, etc.
Use scale of catalytic combustion of organic waste gas: Catalytic combustion can handle almost any hydrocarbon organic waste gas and foul smelling gases. Adsorption-catalytic combustion method is more suitable for low concentration and multi-component waste gas emitted by occupations with no recovery value, such as chemical industry, coating, insulating materials.
Organic waste gas is powered by the fan, pressure or negative pressure into the activated carbon adsorption box, because there is an unbalanced and not full molecular gravity or chemical strength on the solid surface of the activated carbon, therefore, when the solid surface and gas contact, can attract gas molecules, make it concentrated and maintain in the solid surface, polluting substances and then adsorbed, waste gas through the filter adsorption, Enter the dust removal system of equipment, purify gas high altitude qualified emission, full of activated carbon can be recovered and reused, reduce the cost.
The selection of catalytic combustion process for organic waste gas depends on:
(1) The heat released in the combustion process, that is, the type and concentration of combustible substances in the exhaust gas.
(2) ignition temperature, that is, the nature of organic components and catalyst activity.
(3) heat, recovery rate, etc. When the heat recovered exceeds the heat required for preheating, the self-heating equilibrium operation can be completed without the need for an external heat source, which is more economical.
