As a specific embodiment, make complete narration to life refuse processing method provided by the invention below：
After municipal house refuse is sorted, the Recyclables such as building waste, metal class are filtered out, by special compressing baling press, are passed through
100 tons of vertical compression baling press compression, suppresses 3-5 times, the air in rubbish and moisture is extruded, are made repeatedly
1600mmx1850mmx1400mm (the long wide x of x are high) executing garbage, certainly, executing garbage can carry out size cutting according to practical application.
Kiln car (namely bake bricks car) of the executing garbage made through tunnel cave is dehydrated from kiln hood into preheating zone, will be dried
Executing garbage loads closed container by manipulator, and being sent into clinkering zone by kiln car carries out high temperature cabonization, can be by controlling clinkering zone
Temperature realizes that the anoxic of executing garbage in closed container thermally decomposes within 800-1000 DEG C, Volatile pernicious gas, finally
Realize charing.The pernicious gases such as the dioxin that discharges, furans are thoroughly destroyed by fire by high-temp combustion twice, are passed through by air-introduced machine
Flue is transported to desulfurization washing tower purified treatment, realizes qualified discharge.High temperature carbon block after charing enter after cooling zone cooling from
Kiln tail is sent out.Cooling zone is blasted outdoor air by air blower, and the hot blast part after heat exchange passes through kiln wall as auxiliary air
Air outlet is sent into clinkering zone and is used as roasting combustion-supporting, reaches and saves the resultant effect that fuel, the emission reduction energy-conservation of raw material and place give up.
Wherein, executing garbage is sent into preheating zone from kiln hood to be dried, drying time in 0.5-1 hours, then by drying
Rear executing garbage loads closed container, and being sent into clinkering zone by car of baking bricks carries out high temperature pyrolysis, temperature control at 800-1000 DEG C, when
Between control heating rate can be by main valve control of discharging fume within 1-1.5 hours, kiln, total valve opening reduces, and negative pressure draft is small, heating
Speed is reduced.Rubbish carbon block after carbonization enters cooling zone cooling about 1-2 hours, according to chilling temperature regulating time, carbon block
About 70-80 DEG C of outlet temperature.Internal combustion of the carbon block after broken as sintering New wall brick after cooling.
Referring to Fig. 2, the present invention, which also provides a kind of present invention, also provides a kind of domestic garbage treating system, including for pair
The rubbish pretreatment unit that house refuse is sorted, the compression for carrying out compaction moulding to expendable house refuse are beaten
Chartered plane, for the rubbish of compacting is cut cutting machine, for executing garbage carry out charing process tunnel cave and be used for
The desulfurization washing tower of purified treatment is carried out to tail gas.
Further, referring to Fig. 2, the present invention, which also provides a kind of present invention, also provides a kind of domestic garbage treating system,
The sewage accumulator tank that also includes being used to handle moisture content at compressed baling press compression, the connection closed container and described burn till
Band is used to hot blast introducing the air-introduced machine of the sintering zone of tunnel furnace, the disintegrating machine for crushing the rubbish carbon block.
Wherein, throughout between science and engineering sequence, for solid refuse, can be conveyed using conveyer belt, for waste water and gas,
Conveyed by closed conduit, reduce and surrounding environment is polluted, while to realize the purpose to save land, set between each operation
Put rationally compact, to reduce and take up an area and the resource of each link can be recycled and is advisable in layout.
