B, heat accumulation type radiant tube revolving bed is pyrolyzed：By quick lime and the foul smell from rubbish pretreatment unit and organic rubbish Rubbish is supplied into heat accumulation type radiant tube revolving bed is heated to 800 DEG C of left sides under conditions of air is completely cut off in revolving bed pyrolysis oven The right side, organic matter and the volatile matter overwhelming majority contained by it separate out, obtain being pyrolyzed two kinds of products of oil gas and pyrolytic carbon after pyrolysis.Pyrolysis In a ring, furnace bottom can be rotated continuously the burner hearth of the heat accumulation type radiant tube revolving bed used, the organic rubbish obtained after pretreatment Rubbish, loaded by feeding device in heat accumulation type radiant tube revolving bed, be equably laid on furnace bottom, layer thickness about 700mm, furnace bottom Machinery drives furnace bottom continuously to rotate, and the bed of material being layered on furnace bottom rotates with furnace bottom, successively by the preheating section of stove, a reaction Section, two conversion zones and three conversion zones, are finally heated to 800 DEG C or so and complete pyrolytic reaction, the pyrolytic carbon after pyrolysis is by warm The outlet of solution charcoal, which is unloaded, comes out of the stove outer, and immediately enters cooling chamber cooling, pyrolysis oil gas is discharged from multiple pyrolysis oil gas vents of burner hearth.

C, gasification process is carried out in gasification installation：Gasification includes vaporizing system fuel gas and produces combustible gas purifying two parts, Pyrolytic carbon is supplied into gasification installation, air boosts into air blower, is heated in air preheater, removes gasification installation respectively Bottom and returning charge gasifier bed, blender is provided with gasification installation inlet pipeline, is well mixed in this air with steam, sprayed into In gasification installation, another part sprays into returning charge gasifier bed, the residue of gasification installation inner bottom part, finally gives combustible gas and residue, And the part combustible gas is supplied to heat accumulation type radiant tube revolving bed and used as the combustion gas of radiant tube.

D, cement kiln synergetic unit carries out collaboration processing：Inorganic refuse from house refuse pretreatment unit is gentle The inorganic matter warehouse in the residue obtained cement plant sent is put in makeup, and the feed belt of raw material mill is delivered to after grab bucket feeding, metering On, it is milled and is dried into raw material after dispensing with raw material, can be increased for control material composition fluctuation in raw material grinding system Add in-line analyzer.On the one hand alternative part sticks earthy raw materials to inorganic refuse, saves cement raw material input, another aspect residue In poisonous and harmful substance realize harmless treatment by cement solidification effect, and the gross mass of inorganic refuse and residue is not Higher than the 5% of cement entirety proportion scale, the kiln tail gas and heat accumulation type radiant tube that cement kiln synergetic unit is obtained obtain To pyrolysis oil gas supply to TRT and carry out waste heat recovery, and resulting boiler residual air is supplied to cement kiln collaboration Raw material mill on reason device is used as dried medium, and gained sewage in pretreatment unit is supplied to sewage-treatment plant and carried out Processing.

The composition and calorific value of pyrolysis gas are as shown in table 2：
