With the development of industry, the problem of exhaust gas emission is becoming more and more serious, which has caused great harm to the environment and human health. In order to solve this problem, the exhaust gas incinerator came into being. Exhaust gas incinerator is a kind of equipment that treats harmful substances in exhaust gas through high-temperature combustion. According to the type of exhaust gas and the treatment effect, the exhaust gas incinerator can be divided into TNV exhaust gas incinerator and VOC exhaust gas incinerator. This article will introduce the differences between these two types of exhaust gas incinerators in detail.
1. The difference between the processing objects.
TNV waste gas incinerator is mainly used to treat toxic, harmful and combustible industrial waste gas, such as waste gas generated by petrochemical, chemical, pharmaceutical and other industries. TNV exhaust gas incinerator is characterized by high combustion temperature, which can reach more than 1000 meters, which can effectively decompose harmful substances and achieve harmless treatment.
VOC waste gas incinerator is mainly used to treat industrial waste gas of volatile organic compounds (VOCs), such as waste gas generated by automobile manufacturing, furniture manufacturing, printing and other industries. VOC exhaust gas incinerators are characterized by relatively low combustion temperatures, generally between 600-800, and mainly decompose VOCs into carbon dioxide and water vapor through catalysts.
2. The difference in combustion methods.
TNV exhaust gas incinerator adopts direct combustion, which fully mixes the exhaust gas with air, so that the exhaust gas is completely burned at high temperature. This combustion method has high thermal efficiency and complete combustion, which can effectively reduce the concentration of harmful substances in the exhaust gas.
The VOC exhaust gas incinerator uses catalytic combustion to decompose VOCs into carbon dioxide and water vapor through the action of catalysts. This combustion method is suitable for treating low-concentration VOCs exhaust gases, with relatively low combustion temperature and high thermal efficiency.
3. The difference between equipment structure and operating cost.
The structure of TNV exhaust gas incinerator is complex, mainly composed of combustion chamber, heat exchanger, fan and other parts. Due to the high combustion temperature, the equipment materials need to have high heat resistance. As a result, the manufacturing and operating costs of TNV exhaust gas incinerators are relatively high.
The structure of the VOC exhaust gas incinerator is relatively simple, mainly composed of combustion chamber, heat exchanger, fan and other parts. Due to the relatively low combustion temperature and the relatively low performance requirements of equipment materials, the manufacturing cost and operating cost of VOC exhaust gas incinerator are relatively low.
4. The difference between environmental protection and resource utilization.
TNV exhaust gas incinerator can effectively reduce the concentration of harmful substances in the exhaust gas and reduce the pollution to the environment due to its high thermal efficiency and complete combustion. At the same time, the heat energy generated during the combustion process can be used to generate electricity or heat to achieve the reuse of resources.
Although the VOC exhaust gas incinerator cannot completely convert VOCs into harmless substances, it can decompose most of the VOCs into harmless substances through catalytic combustion and reduce environmental pollution. In addition, the heat energy generated by catalytic combustion can also be used to generate electricity or heat for the reuse of resources.
