Description
Technical field
This utility model patent relates to green technology and apparatus field, is specially a kind of garbage burning flying dust treating system based on minimizing.
Background technology
Along with the quickening with urbanization process that develops rapidly of national economy, urban life rubbish
The generation amount of rubbish grows with each passing day. 261 the big or middle Municipal Domestic Garbage Outputs in the whole nation in 2013 reach 1.61 �� 108T, and increase rapidly with the speed of annual 10%, " garbage-surrounded city " has become the significant problem that urban development is urgently to be resolved hurrily. Burning method substantially due to reduction and can produce electric energy and obtains and greatly develop. According to " the application of city life garbage harmless treatment Facilities Construction planning of " 12 " whole nation " requirement, by 2015, national application of city life garbage burning disposal facility ability reached more than the 35% of harmless treatment total capacity, and its Middle Eastern reaches more than 48%. It can be said that China's consumer waste incineration processes the gold period having been enter into fast development. But, Refuse Incineration Process also can produce the flying dust of about 3%, specify according to national standard (GB18485-2001), incineration of refuse flyash is owing to being listed in danger wastes containing substantial amounts of two English and heavy metal.
72%Zn, 24%Cr, 46%Cd, 30%Ni, 36%Cu, 86%Pb in rubbish transfer in incineration of refuse flyash, and the dioxin in incineration of refuse flyash accounts for more than the 90% of total release.
