Description
Technical field
The present invention relates to technical field of domestic garbage treatment, specially a kind of villages and small towns house refuse high-efficiency cleaning minimizing is comprehensive
Close processing method.
Background technique
Domestic rubbish disposal refers exclusively to daily life or provides solid waste caused by the activity of service for daily life
The processing of the solid waste for being considered as house refuse of object and laws and regulations defined, it is Sources decreasing including house refuse, clear
It sweeps, categorised collection, storage, transport, processing, disposition and related management activity.
Domestic rubbish disposal the purpose is to reduce Municipal Garbage Yields, be more suitable for " matter " (ingredient and the characteristic) of rubbish with " amount "
The requirement of subsequent processing goods final disposal, garbage disposal follow minimizing, innoxious, recycling, saving fund, Economization on land and
Criterion, adaptation to local conditions, the integrated treatments such as resident's satisfaction are reduced step by step, and the existing processing mode to house refuse, which generallys use, to be covered
The mode buried or burned is handled, and the mode of burial not only wastes a large amount of soils and garbage degradation needs many years, and
The mode of burning then pollutes environment, thus it is proposed that a kind of villages and small towns house refuse high-efficiency cleaning minimizing integrated conduct method comes
It solves the above problems.
Summary of the invention
The object of the present invention is to provide a kind of villages and small towns house refuse high-efficiency cleaning minimizing integrated conduct methods, and having makes to give birth to
The advantages of rubbish living is utilized during the treatment, is not only made garbage decrement and is effectively achieved recycling, solves
The problem of being proposed in background technique.
Technical solution
To achieve the above object, the invention provides the following technical scheme: a kind of villages and small towns house refuse high-efficiency cleaning minimizing is comprehensive
Processing method, steps are as follows for the villages and small towns house refuse high-efficiency cleaning minimizing integrated treatment:
S1, through collected come house refuse it is of short duration be stored in garbage storing hole, store certain time, carry out fermentation process, storage hole in
Landfill leachate is promoted to device for treating leachate through sewage pump and is handled;
S2, landfill leachate generate after processing in water and sludge, water supplements new water source as water in proportion during treated
Spray system uses;
House refuse is transported to magnetic plant through grab claw in S3, storage hole;
S4, rubbish enters in crusher and is crushed after magnetic separation;
S5, broken rear rubbish enter cylinder round sifter and sieve to rubbish, screen out fertile soil and individually store, most of rubbish
Enter garbage pusher machine entrance for oversize;
S6, broken rubbish are delivered to biomass pyrogenation gasification furnace through pusher, are pyrolyzed, rubbish is through pyrolysis gas of biomass
After changing furnace pyrolysis, pyrolysis residue and pyrolysis gas are generated;
S7, pyrolysis residue are mixed with percolate sludge and fertile soil after screening carries out the organic base manure of fermentation generation, and on sieving
Object can be used as brickmaking filler;
S8, the pyrolysis gas enter water spray after the pyrolysis of biomass pyrogenation gasification furnace and spray to it, and the water after spray enters
Processing equipment is handled;
S9, the pyrolysis gas after spraying enter cyclone system and are dusted work;
Pyrolysis gas after S10, dedusting enters gas fired-boiler and burns;
Exhaust gas after S11, gas fired-boiler burning enters multi-step dust collector and is dusted depickling;
S12, flue gas enter plasma catalytic oxidation unit after Multi-stage dust removing device;
S13, flue gas are after plasma catalytic is handled, into efficient absorption device, the final qualified discharge of flue gas.
Further, the magnetic plant in the step S3 is belt magnetic separator, and one end is permanent magnet transmission shaft, can be had
Effect recycles metal product.
Further, the crusher in the step S4 is shear crusher, impact breaker, scraper type crusher
Or any one of swing hammer crusher, crusher range of choice is big, effectively save operation cost of enterprises.
Further, the preferred shear crusher of the crusher, and preferably Double-shaft shearing crusher, crushing effect reach
To optimal selection.
Further, in the step S5 cylinder round sifter rotary screen discharge partial size≤5mm, preferably rotary screen discharge grain
Diameter≤3mm, screening effect are good.
Further, pusher carries out feeding by the way of hydraulic push in the step S5, and feeder length 3~
5m, push function pushes broken rubbish, to reduce manual labor.
Further, in the step S11 multi-step dust collector be ceramic whirlwind multi-tube dusting, pulsed jet cloth filter,
One of electric precipitator perhaps two kinds series connection and deacidification agent selection CaO, Ca (OH) 2, one of or two kinds of dry powder or

Further, adsorbent used in efficient absorption device selects activated carbon adsorption in the step S13, specific to select
With multistage activated carbon adsorption net or cellular activated carbon adsorption, adsorbed again to be discharged into the flue gas in atmosphere, it can be to it
Effectively de-tasted.
1, the villages and small towns house refuse high-efficiency cleaning minimizing integrated conduct method is cheated by setting garbage storing, can be to rubbish
Solid-liquid classification is carried out, by handling various forms of rubbish, treatment effeciency is higher, and water and sludge are equal during treated
Can be recycled, by the way that crusher is arranged, solid refuse can be carried out it is effectively broken, avoid garbage bulk it is excessive lead it is subsequent not
Benefit reason can be pyrolyzed the house refuse, the gas generated after pyrolysis contains by the way that biomass pyrogenation gasification furnace is arranged
The imflammable gas such as CO, H2, CH4, to facilitate later process to use, and be pyrolyzed after waste can be used as organic base manure and
It can be used as brickmaking filler, do not only reached the purpose for making garbage decrement, and can make that treated substance is utilized effectively.
2, the villages and small towns house refuse high-efficiency cleaning minimizing integrated conduct method, by the way that multi-step dust collector is arranged, not only
The dust mixed in rubbish can effectively be filtered, and effective depickling can be carried out to flue gas, effectively to prevent acid rain
It generates, the organic exhaust gas such as dioxin in exhaust gas is further decomposed by the way that ionic catalysis oxidation unit is arranged, by setting
Setting the device can be such that waste after domestic rubbish disposal is comprehensively utilized, and will not generate secondary pollution to environment, be a kind of high
Imitate clean processing method.
