发明名称
一种处理城市生活垃圾的方法
摘要
本发明涉及处理城市垃圾的方法。该方法是将城市生活垃圾按40—100mm筛分,筛上物送入焚烧炉,焚烧产生的热量回收利用,产生的灰直接填埋;筛下物经高温高压处理后可用做肥料或饲料的原料。该方法可完全达到垃圾处理的无害化、减量化,其减量高达85%,同时实现资源化,其资源化达65%以上,因此该方法具有极大的社会效益和经济效益。

1、一种处理城市生活垃圾的方法,其特征在于该方法是将城市生活垃圾人工分选捡出大快金属,再按40-100mm粒径分离,大于该值为筛上物,小于该值的为筛下物,其筛上物送入焚烧炉燃烧,燃烧产生的热量用于加热油炉为后续工序高温高压釜提供热源。或/和加热吹入焚烧炉的空气,或/和冬天采暖;燃烧产生的灰直接填埋;筛下物装入高温高压釜内,将筛下物的含水量调节到50-60%,再在温度150-200℃,压力4.8-16个大气压下处理0.5-2小时,其垃圾变为泥状,接着排气除去水蒸汽,使其含水量达到40%,让其垃圾喷出,喷出的已处理垃圾再筛分,筛上垃圾送入焚烧炉焚烧,筛下垃圾经磨碎后做肥料或动物饲料原料。
