The invention discloses a low energy consumption system for purifying and incinerating harmful gases. The low energy consumption system consists of main body units such as a waste gas purifying and incinerating unit, a waste heat recovering unit and a flue gas treating body unit as well as auxiliary equipment such as fuel equipment, combustion-supporting air equipment, heat exchange medium equipment and harmful gas adsorbent equipment. According to the low energy consumption system, due to the adoption of various latest energy-saving combustion technologies and energy-saving emission-reducing measures, the optimization is carried out from the whole, the problems that energy consumption of a DTO (Direct-Fired thermal Oxidizer) of a conventional chamber type waste gas incinerator is over high, RTO (Regenerative Thermal Oxidizing Furnace) waste gas of a reversed heat accumulation type waste gas incinerator is not completely combusted, a heat accumulator is blocked by dust-containing waste gas and the like are solved and various harmful waste gases can be continuously purified and incinerated at low cost. Due to the adoption of a brand-new heat accumulation incineration mode, the low energy consumption system has the characteristics that the heat accumulator is easy to clean for avoiding blocking, the harmful waste gases are completely incinerated and discharged after reaching the standard, the energy-saving effect is remarkable and the like. In addition, due to the adoption of measures of selecting an oxygen-enriched combustor, matching with oxygen-enriched and combustion-supporting air supply equipment, providing hot air for incineration to support combustion and the like, the consumption of auxiliary fuel can be effectively reduced, the incineration treatment expenses are reduced and the popularization and the application are facilitated.
Description
technical field [0001] The invention relates to a system for purifying and incinerating harmful waste gas with low energy consumption, which belongs to the field of environmental protection and waste gas incineration treatment technology. Background technique [0002] Hazardous waste gas refers to waste gas containing components that are harmful to human body and environment, such as production waste gas containing volatile organic compounds (VOC) in petrochemical, chemical, spraying, copper-clad laminate and other industries, and pyrolysis gas from waste incineration. The most thorough harmless treatment method for harmful waste gas is incineration. The methods of incineration of waste gas are: [0003] Direct fired thermal oxidizer (DTO) is a kind of hazardous waste gas incinerator. The main body consists of auxiliary fuel, mixing zone and combustion chamber. The heat generated by the combustion of auxiliary fuel (natural gas, diesel, etc.) preheats the harmful exhaust ...
