Thus, it is organic that the system of process house refuse according to embodiments of the present invention obtains after by house refuse pretreatment
Rubbish and foul smell supply and carry out pyrolysis processing to heat accumulation type radiant tube revolving bed, can obtain being pyrolyzed oil gas and pyrolytic carbon,
Such that it is able to avoiding garbage loading embeading or burning the wasting of resources leading to, and can be burnt away the refuse with effectively solving by pyrolysis processing
Gained pyrolytic carbon is supplied simultaneously and obtains combustible gas and residue to gasification installation by the problem of the two English pollutions being brought, and will
Gained combustible gas returns and uses as combustion gas as in heat accumulation type radiant tube revolving bed, and obtained residue supplies to cement kiln association
It is used as cement slurry with cooperation limestone, clay matter etc. in processing unit, so effectively not only can reduce cement cost, and
And so that rubbish waste residue is fully utilized, such that it is able to garbage disposal is organically combined with cement kiln synergetic unit
Get up, with respect to existing cement kiln synergic processing method, in this application, once cement kiln production line stops production, life rubbish
Rubbish can also be pyrolyzed in advance, will not bank up smelly, produces the problem that rubbish nowhere can be put, in addition, having during gasification is residue obtained
Evil noxious substance is solidified through cement, thus realizing the innoxious of house refuse and recycling treatment.
In addition, the system processing house refuse according to the above embodiment of the present invention can also have the technical characteristic adding as follows：
In some embodiments of the invention, the described system processing house refuse further includes：Oil-gas Separation purifier,
