一种富氧条件下加热熔融处理垃圾装置及方法
摘要：
本发明公开了一种富氧条件下加热熔融处理垃圾装置及方法，包括垃圾熔融炉，所述垃圾熔融炉与氧气供给系统连接，垃圾熔融炉底部与冷却装置连接；所述氧气供给系统包括依次连接的空气分离装置、送风机、空气预热器，所述垃圾熔融炉的上部设置第一吹风口，垃圾熔融炉的底部设置第二吹风口，第一吹风口和第二吹风口均与空气预热器连通；氧气供给系统将分离出的富氧气体提供给垃圾熔融炉，利用富氧气体作为氧化剂对垃圾进行熔融处理。利用富氧燃烧和熔融处理的优势，利用燃料的燃烧热，在高温下使垃圾飞灰熔融，冷却后成为稳定的玻璃态熔渣，并破坏二恶英等有机成分，将大部分重金属固化在玻璃态熔渣中。
摘要（英）：

The invention discloses a device and method for heating and melting rubbish under the oxygen-rich condition. The device comprises a rubbish melting furnace. The rubbish melting furnace is connected with an oxygen supply system. The bottom of the rubbish melting furnace is connected with a cooling device. The oxygen supply system comprises an air separation device, an air feeder and an air preheater which are connected sequentially. A first air blowing opening is formed in the upper portion of the rubbish melting furnace. A second air blowing opening is formed in the bottom of the rubbish melting furnace. Both the first air blowing opening and the second air blowing opening communicate with the air preheater. The oxygen supply system supplies separated oxygen-rich gas to the rubbish melting furnace, and the oxygen-rich gas is used as an oxidizing agent for melting the rubbish. The beneficial effects of the oxygen-rich combustion and melting treatment are used, combustion heat of fuel is used, fly ash of the rubbish is molten at the high temperature, stable glassy state slag is formed after cooling, organic components of Dioxin and the like are destroyed, and most of heavy metals are solidified in the glassy state slag.
