In a ring, furnace bottom can be rotated continuously the burner hearth of radiant tube revolving bed, the organic waste obtained after pretreatment, by feeding device
Load in heat accumulation type radiant tube revolving bed, be equably laid on furnace bottom, layer thickness about 700mm, furnace bottom machine drives furnace bottom
Continuous to rotate, the bed of material being layered on furnace bottom is rotated with furnace bottom, sequentially pass through the preheating section of stove, a conversion zone, two conversion zones and
Three conversion zones, are finally heated to 800 DEG C or so and complete pyrolytic reaction, and the pyrolytic carbon after pyrolysis is unloaded by pyrolytic carbon outlet and come out of the stove
Outside, and cooling chamber cooling is immediately entered, pyrolysis oil gas is discharged from multiple pyrolysis oil gas vents of burner hearth.
C, cement kiln synergetic unit carry out collaboration processing：The pyrolytic carbon supply that heat accumulation type radiant tube revolving bed is obtained
Preheater, dore furnace and rotary kiln to cement kiln synergetic unit are used as fuel, are pre-processed and are filled from house refuse
Inorganic matter warehouse in the cement plant that the inorganic refuse put is sent, is delivered on the feed belt of raw material mill after feeding of grabbing bucket, metering,
It is milled and is dried into raw material after dispensing with raw material, can be existed for the fluctuation of control material composition in the increase of raw material grinding system
Line analysis instrument.On the one hand alternative part sticks earthy raw materials to inorganic refuse, saves cement raw material input, another aspect inorganic refuse
In poisonous and harmful substance realize harmless treatment by cement solidification effect, and inorganic refuse gross mass is not higher than cement
The 5% of overall proportion scale, the kiln tail gas that cement kiln synergetic unit is obtained supply to TRT and carry out waste heat time
Receive, and using resulting boiler residual air supply to cement kiln cooperate with processing unit on raw material mill used as dried medium.
D, Oil-gas Separation purifier carry out pyrolysis oil gas purification separation：Pyrolysis oil from heat accumulation type radiant tube revolving bed
Gas passes through wet dedusting tower, after the dust carried in pyrolysis oil gas is removed, into the transverse pipe initial coolers of two parallel operations, then
The electrical tar precipitator operated simultaneously into two parallel connections, completes to remove the tar work carried secretly in pyrolysis gas, then by coal gas Roots
Pyrolysis gas is delivered to dry desulfurization process by air blower, and the pyrolysis oil got off by gas-liquid separator separates and circulation pyrolysis water enter machine
Tool oil-water separation tank, is circulated pyrolysis water, the separation of pyrolysis oil, i.e., isolated pyrolysis oil and sewage, and will divide herein
It is stored in flammable gas storage tank, and is supplied through flammable gas storage tank to heat accumulation type radiant tube revolving bed as spoke from obtained pyrolysis gas
Pipe combustion gas is penetrated to use, the pyrolysis oil that Oil-gas Separation purifier is obtained supply to the preheater of cement kiln synergetic unit,
Dore furnace and rotary kiln are used as fuel, and gained sewage in sewage obtained by Oil-gas Separation purifier and pretreatment unit is supplied
Handled to sewage-treatment plant.
