Step improves the efficiency of drying and dehydrating, and the drying house refuse for ensureing to obtain has relatively low water content；At the same time it can also advance
Vapor and flue gas are heated, resupplied into each steam heat-exchanging chamber, so as to further improve to pending life rubbish
The efficiency that rubbish is heated or is incubated.
According to embodiment of the present utility model, the first steam heat-exchanging chamber, the second steam heat-exchanging chamber and the 3rd steam change
It is provided with hot chamber and leads shower pipe, the port of export for leading shower pipe is in communication with the outside.Thus, it is possible to each steam is changed using shower pipe is led
The condensed water that high-temperature vapor condenses to obtain in hot chamber is collected and device for transferring.
According to embodiment of the present utility model, spiral dehydration furnace can further include steam lead, and steam lead can
To be arranged in one-level dry section, secondary drying area and three-stage drying area, steam lead is provided with multiple steam entries, steam
The port of export of conduit is connected with the first steam heat-exchanging chamber, the second steam heat-exchanging chamber and the 3rd steam heat-exchanging chamber respectively.
Thus, it is possible to the vapor for being dried to obtain house refuse using steam lead is delivered in each steam heat-exchanging chamber.
Thus, according to the method for the processing house refuse of the utility model embodiment by the way that pending house refuse is supplied
To spiral dehydration furnace, under the propulsion of spiral dehydration furnace auger conveyor, pending house refuse is successively by feed zone, one
Level dry section, secondary drying area, three-stage drying area, and the burner combustion by being set in dry sections at different levels produces heat smoke pair
Dehydration is dried in pending house refuse, obtains drying house refuse and vapor, wherein drying house refuse by material discharge region
Discharge, vapor are discharged by steam outlet, and heat smoke caused by burner combustion completes the drying and dehydrating to house refuse
Afterwards, discharged by the exhanst gas outlet of material discharge region；Wherein, vapor and flue gas can enter each in dry section side walls at different levels
It is used to pending house refuse is heated or is incubated in steam heat-exchanging chamber, the condensed water for condensing to obtain can be by leading shower pipe
Discharge spiral dehydration furnace is collected；And then dry house refuse and be pyrolyzed into revolving bed pyrolysis oven, to be pyrolyzed
Oil gas and solid residue；Because pending house refuse completes drying and dehydrating before being pyrolyzed, caused pyrolysis oil gas is pyrolyzed
The pyrolysis oil being pyrolyzed in oil gas directly can be condensed by recovery using the oily type of cooling, so as to avoid water content in pyrolysis oil gas
The problem of processing difficulty caused by too high and high cost, and by predrainage vapor in pyrolytic process can be avoided to expend radiation
Tubular heat, and the pyrolysis oil for avoiding vapor from being obtained with pyrolysis is reacted, so as to further improve the yield and quality of pyrolysis oil, heat
Vent one's spleen to return after removing sour gas and be used as burner and radiant tube fuel.Thus, this method takes off by using spiral
Water stove is dehydrated in advance to pending house refuse, significantly improve pyrolysis oil gas quality, and reduce Oil-gas Separation into
This, and the continuous stable and reliable operation of equipment, the thermal efficiency is high, and economic benefit is obvious.
