Abstract

The invention discloses a resource recovery type household garbage processing method. When garbage falls down under the action of self-gravity, plastic bag crushing blades, which rotate in the same direction, tear the plastic bags, which wrap the household garbage; the garbage falls into a cylinder of a sorting device, then the garbage is sorted in the cylinder; the plastic garbage is transported to a crushing device to crush; the kitchen garbage is transported to a curing chamber to carbonate, carbides and marsh gas are generated during the carbonation process; the crushed plastic garbage is transported to a liquidizing chamber in a vacuum state, the crushed plastic garbage is liquidized to generate liquefied gas, the liquefied gas enters a liquidizing tank set through a pipeline, is cooled in the liquidizing tank set, and is converted into liquefied oil; and finally the carbides generated in the liquidizing chamber and the curing chamber are discharged out of the system and taken as chemical raw materials. The processing method has the advantages that: the garbage is sorted, the sorted garbage is subjected to different recovery methods, thus the comprehensive recovery of recyclable resources is realized, garbage is greatly reduced, a lot of soil resources and recyclable valuable resources are saved, and the ecological environment is protected.

Description

A kind of resource reclaiming type life refuse processing method

Technical field

A kind of resource reclaiming type of the present invention life refuse processing method, what relate to is Prediction for Solid Waste Treatment Technology field, is applied to separating domestic garbage processing, reclaims available resources.

Background technology

The mode that treatment of urban garbage both domestic and external mainly adopts landfill, store up is processed house refuse, and in expansion and Rural Urbanization Process along with city, the total amount of house refuse constantly increases.Landfill, store up and not only need to take a large amount of soils, and can produce a large amount of toxic and harmfuls, can cause secondary pollution to soil and groundwater, cause landfill field boundary periphery ecological environment severe exacerbation.Then adopt again the method for burning to carry out harmless treatment to house refuse.For example, various places utilize the burning of house refuse, generate electricity, and are a kind of approach of resource reutilization.But, in the process of burning domestic garbage, can produce a large amount of toxic and harmfuls, though through effectively processing, still have certain toxic and harmful to be diffused in air, contaminated air, the sound of public's protest can be heard without end.How in house refuse is being burned recovery resource process, to remove all kinds of hazards, fully reclaim available resources, reach energy-saving and emission-reduction, preserving the ecological environment is the great section topic of government and insider's research.

Summary of the invention

The object of the invention is to from economizing the land resource, eliminate the hidden danger that various toxic and harmfuls produce, fully reclaiming available resources sets out, garbage disposal is studied, design is a kind of sorts in course of conveying, and by its pulverizing, respectively the organic domestic waste sorting out being carried out to maturation process makes fertilizer and produces biogas, simultaneously, utilize biogas heating, heavy chemicals is evaporated in airtight container and produce steam, again that steam is cooling, reclaim available resources, make house refuse reach minimizing, innoxious, a kind of resource reclaiming type life refuse processing method of resource.

Its technology is achieved in that and comprises by the garbage feeding bucket of thinking of a way, sorting equipment, pulverize carrier chain, vapourizing furnace, liquefied pot, the order of holding vessel fixes on the ground and overlaps, it is characterized in that: pass through in the time that gravity is descending at rubbish, by homodromal polybag crushing knife, the polybag of parcel house refuse is torn, fall in the cylindrical shell of sorting equipment and sort, plastic garbage enters reducing mechanism and pulverizes, garbage is sent into curing chamber and is carried out carbonization, produce carbide and biogas, the liquefied room that plastic garbage is sent under vacuum state produces liquefied gas tank, liquefied gas tank enters the cooling of liquefied pot group by pipeline, produce liquefaction oil, by liquefied room, the carbide that curing chamber produces is sent as industrial chemicals, the chamber temperature of described vapourizing furnace is at 150～500 ℃, vacuum when vapourizing furnace liquefied room works is at-0.01～-0.10Mp.

Obvious advantage and the effect implemented after this technology are: be first to have overcome landfill, store up and need to take a large amount of soils, and can produce a large amount of toxic and harmfuls, can cause secondary pollution to soil and groundwater, cause the defect of landfill field boundary periphery ecological environment severe exacerbation.By sorting, make house refuse obtain classification, sort out object and adopt different ways of recycling, realize the comprehensive available resources that reclaim, rubbish is carried out to minimizing processing, save a large amount of land resource and reclaimed available resources, protect ecological environment.

The specific embodiment

Be below example by the house refuse of 10T/h treating capacity, the invention will be further described:

Requirement according to resource reclaiming type life refuse processing method: the structure of the treatment facility of this processing method, the structure that fixes on the ground and overlap by the order of the garbage feeding bucket of thinking of a way, sorting equipment, pulverizing carrier chain, vapourizing furnace, liquefied pot, holding vessel.

Set by pressing 10T/h, garbage truck is poured rubbish in hopper into, pass through in the time that gravity is descending at rubbish, by homodromal polybag crushing knife, the polybag of parcel house refuse is torn, house refuse in polybag and polybag continuously falls in the cylindrical shell of sorting equipment, hinge cage in the cylindrical shell of sorting equipment, roll is in rotary course, by after building waste grating by building materials conveying mouth, metallics output, ferrous metal is drawn by electromagnet, remaining rubbish falls on mesh-belt conveying chain by the cylindrical shell bottom outlet of sorting equipment, along with the motion of mesh-belt conveying chain, plastic garbage enters reducing mechanism, garbage falls into the garbage that belt conveyor and reducing mechanism fall and falls into respectively kitchen useless hinge cage, send into curing chamber by kitchen useless hinge cage and carry out slaking, produce carbide and biogas, the biogas producing is for combustion chambers burn heat supply, the plastic garbage that sorting equipment separates is along with mesh-belt conveying chain moves upward, plastic garbage is sent into reducing mechanism to be pulverized, the plastics of reducing mechanism output, package fragment falls into the carrier chain 8 of motion, carrier chain is by the plastics of reducing mechanism output, package fragment is sent into liquefied room, under the effect of the biogas of combustion chambers burn, when liquefied room's temperature of vacuum state reaches 250 ℃, plastics, package fragment is vaporized, produce liquefied gas tank, in addition, in the time of 250 ℃, garbage is carbonized in curing chamber, liquefied gas tank enters the cooling of liquefied pot group by pipeline, produce liquefaction oil, liquefaction oil constantly flows into holding vessel, in addition, the carbide being produced by liquefied room, curing chamber, respectively by the hinge cage being provided with separately, is sent as industrial chemicals, and the water that liquefied gas tank produces in being cooled to liquefaction oil flows into water collector, concentrates and sends.Complete making full use of of garbage sorting and resource, realize the double effects that decrement treatment house refuse and resource reclaim.
