  • 摘要: 气化熔融焚烧技术能够避免重金属和二恶英的二次污染，被公认为实现零排放和环境友好型的焚烧方法。在这样的背景下提出了生活垃圾并流竖炉气化熔融焚烧工艺。该工艺以竖炉为气化熔融主体设备，垃圾料层与助燃空气在炉内都是至上而下并流流动，从而使垃圾热解气化产生的可燃气体在竖炉下部完全燃烧，以提供灰渣熔融耗热。并流竖炉热态模拟试验表明，并流时垃圾料层中各点的温度明显高于逆流情况，并流时产生的CO2量明显高于逆流情况。因此说并流竖炉更适合气化熔融焚烧工艺的要求。
    Abstract: In all the municipal solid waste（MSW）disposal technology, incineration with gasification and melting has been taken as a environmentally sound and zero emission technology owing to avoid second-pollution of heavy metals and dioxin. In this background, a direct gasification and melting incineration process with co-current shaft furnace is put forward. In the new process, the main equipment is a shaft furnace. In which, MSW and combustion-supporting air are co-current from top to bottom. Fuel gas from pyrolysis and gasification burns completely in the bottom in order to offer energy for slag melting. The simulation experiment of the co-current shaft furnace has been done. The results of simulation experiment show that the temperature on the condition of co-current is much higher than under the condition of countercurrent and more CO2 are discharged from cocurrent reaction tube. It can be concluded that the co-current shaft furnace is more suitable for direct gasification and melting incineration process.

摘要: 气化熔融焚烧技术能够避免重金属和二恶英的二次污染，被公认为实现零排放和环境友好型的焚烧方法。在这样的背景下提出了生活垃圾并流竖炉气化熔融焚烧工艺。该工艺以竖炉为气化熔融主体设备，垃圾料层与助燃空气在炉内都是至上而下并流流动，从而使垃圾热解气化产生的可燃气体在竖炉下部完全燃烧，以提供灰渣熔融耗热。并流竖炉热态模拟试验表明，并流时垃圾料层中各点的温度明显高于逆流情况，并流时产生的CO2量明显高于逆流情况。因此说并流竖炉更适合气化熔融焚烧工艺的要求。
