Technical field
The present invention relates to a kind of refuse disposal installation, specially a kind of rubbish row screening fluidisation pyrolysis installation.
Background technique
Refuse pyrolysis is the garbage disposal means that developed country is widely used, in great shortage country of ploughing in Japan etc., rubbish
It burns pyrolysis processing ratio and reaches 65-80%.But conventional garbage burns pyrolysis treatment device and has the following disadvantages:
It can not achieve at burning pyrolytic process first is that conventional garbage burns pyrolysis installation while rubbish sieved automatically
Point, progressive pyrolysis of classifying is carried out, blocking for burning process is easy to happen, makes pyrolysis state, makes to prevent dioxin from generating environment protection thermal
Solution is difficult to realize.It is more containing life organic matter and plastics, glass, tile, metal, cement block etc. in conventional garbage mixture
Kind ingredient, classification processing difficulty is big before burning, at high cost, so actually mostly using garbage mixture directly to enter furnace burns pyrolysis.
But garbage mixture does not sieve that directly to enter furnace to burn pyrolysis the problem of bringing be that incineration temperature is difficult to adapt to be easy to produce two simultaneously
It dislikes the organic waste of English and be easy to cause the inorganic refuse for blocking, influencing burning state and deslagging.The congestion of burning process is blocked,
Not only increase maintenance cost, but also change burning state, influences to burn the control that leading portion inhibits dioxin to generate, increase subsequent
The difficulty and expense of dioxin processing increase the possibility that subsequent gas cleaning removing dioxin-like chemical causes secondary pollution
Property.
