Direct-fired incinerators (TO)
Direct-fired incinerators (TO)
Comprehensive overview
The direct-fired incinerator, which utilizes the heat generated by the combustion of auxiliary fuels, raises the temperature of combustible hazardous gases to the reaction temperature so that oxidative decomposition occurs. The equipment has a small footprint, high combustion efficiency, easy management, and waste heat can be recycled.
Working Principle
Direct-fired incinerator processing temperature of 750 ~ 850 ℃, at this temperature, the harmful air pollutants will be processed into carbon dioxide and water, the exhaust gas through the combustion chamber time of 0.5 seconds or more. New plate and shell and tube heat exchangers are designed to preheat the organic waste gas entering the oxidizer. The treatment efficiency of volatile organic compounds VOCs can be higher than 99%.
Typical Processes
Main features
- Remarkable deodorization effect, stable operation, high purification efficiency, without the worry of secondary public health. The use of thermal method of combustion oxidative decomposition of malodorous gases, in the appropriate temperature, provide sufficient combustion oxygen and a certain residence time, you can achieve deodorization efficiency, purification effect is good. At the same time, the host of the equipment works stably, there is no catalyst aging, clogging phenomenon, solves the problem that other waste gas treatment methods can not be solved, and no secondary pollutants.
- Simple operation, easy maintenance, safe and reliable operation of the device burner using automatic oil supply (gas), automatic adjustment of the combustion temperature way to work. The burner is easy to maintain, and at the same time, considering the explosion concentration of organic waste gas in the equipment, there are anti-temperature, explosion-proof pressure relief measures in the structure.
- Low operating costs, waste heat can be recovered and utilized with the changes in exhaust gas concentration, combustion temperature changes in a timely manner to feedback, automatically adjust the amount of oil (gas), can reduce the true operating costs, while optional heat exchanger, waste heat reuse, to achieve energy-saving efficiency.
Field of application
Direct-fired incinerator, suitable for spraying and drying equipment exhaust gas treatment, and petrochemical, pharmaceutical and other industries emit harmful gas purification. Organic waste gas containing water-soluble or viscous substances and polymer substances in the gas purification shows its advantages. It meets the requirements of environmental protection and labor protection, and at the same time increases the heat exchange equipment to achieve the purpose of waste heat reuse and energy saving.
- Purification and treatment of organic solvent gas mixtures generated in spray painting and drying (electrophoretic paint drying) in machinery, automobile, motorcycle, household appliances, tractor and other industries.
- Applicable to chemical plants, pharmaceutical plants, coating plants, synthetic resin plants, film plants, organic chemical plants and other enterprises in the production process of excess waste gas purification and treatment.
- It is suitable for the purification of chemical substances (gases) such as NH3, CH2=CHCHO, CH2H5NH2, C6H4(CH3)2, C6H5CH3, C6H5OH, HCHO, CH3SH and so on.
