背景技术 Background technique
随着国家对危废处置工作的重视以及地区经济建设的快速发展，地区的危险废物处置量不断增多，危废类别复杂，如图1所示，传统技术中主处理工艺是废弃物直接进入焚烧炉中焚烧，产生的废烟气经过二次燃烧室的处理后，再进入喷淋洗涤塔中处理，最后废弃排放，废液进行沉淀处理。这种传统的热解焚烧炉及配套技术相对落后，在焚烧处置废弃物的种类上存在一定的局限性，焚烧化工残渣、污泥、胶状废弃物时能耗高、时间长。 With the country's emphasis on hazardous waste disposal and the rapid development of regional economic construction, the amount of hazardous waste disposed of in the region is increasing, and the types of hazardous waste are complex. As shown in Figure 1, the main treatment process in traditional technology is that waste is directly incinerated Incinerated in the furnace, the waste flue gas produced is treated in the secondary combustion chamber, then enters the spray scrubber for treatment, and finally discards and discharges, and the waste liquid is subjected to precipitation treatment. This traditional pyrolysis incinerator and supporting technology are relatively backward, and there are certain limitations in the types of incineration and disposal of waste. The incineration of chemical residues, sludge, and colloidal waste requires high energy consumption and takes a long time.
