Description
Technical field
The present invention relates to technical field of waste treatment, more specifically, it relates to a kind of waste gas generated by burning garbage and flying dust
Coprocessing system.
Background technique
In recent years, due to consumer waste incineration processing has the characteristics that minimizing is big, resource utilization is high and increasingly by
To concern.But poison gas, bottom ash and flying dust can be generated during incineration treatment of garbage, this popularization for also constraining the technology is answered
With.Therefore, Pollution in Municipal Solid Waste Incineration control becomes the hot spot of field of environment engineering research.Wherein the yield of flying dust is about to live
The 2%-5% of rubbish quality not only contains the heavy metal contaminants of the high concentrations such as Pb, Hg, Cu, Cd, Zn, Ni and Cr in flying dust,
Also containing organic pollutants such as dioxin, therefore, incineration of refuse flyash is put into danger wastes register (HW18).Waste incineration
Flying dust has extremely strong teratogenesis and carcinogenic toxicity, once being arbitrarily discharged into environment, harmfulness is self-evident.
Currently, the innoxious process for treating of incineration of refuse flyash have melting/glass solidification, cement solidification, chemical stabilization method,
Sour or other solvent wash methods etc..In the prior art, the Chinese invention patent file that application publication number is CN102173721A is public
The consolidation method of a kind of incineration of refuse flyash consolidating agent and incineration of refuse flyash is opened, which has the huge sum of money reduced in flying dust
The advantages of belonging to Leaching.But the performance of pitch can be reduced in actual use, on the other hand still have an a small amount of huge sum of money
Category leaks, and causes secondary pollution.
