Abstract
A kind of domestic waste composite highly effective recycling treatment process, including rubbish pretreatment, refuse gasification, purified synthesis gas, biochemical treatment and wastewater treatment, domestic waste are converted into gaseous fuel or liquid fuel after processing.Domestic waste produces synthesis gas using high-temperature gasification technique, avoids generation dioxin toxicant during incineration firing.Liquid fuel is produced using biochemical conversion process after purified synthesis gas, purified rear international sale, liquid fuel price is higher, substantially increases value-added content of product, improves the self-management ability of destructor plant.According to the energy demand situation on garbage disposal plant area periphery, is burnt using artificial fuel gas and produce electric power, steam or hot water, improve the production chains of garbage disposal plant area.The defeated solid residue of off-site and waste realize harmless treatment, it can be achieved that security landfill or using as building materials.Plant area's waste water joint disposal realizes plant area's wastewater zero discharge.
Description
Technical field
The present invention relates to domestic rubbish disposals to utilize technical field, in particular to a kind of domestic waste composite highly effective money
Source treatment process.
Background technique
With the acceleration of urbanization process, domestic waste yield is continuously increased, and causes serious environmental pollution, such as
The important topic what studies the present age its innoxious and recycling treatment.
China's garbage disposal at present is based on filling, supplemented by compost and burning, but landfill, compost have larger problem,
There are the secondary pollutions such as flue gas is exceeded, foul smell disturbs residents, dioxin and heavy metal in waste incineration, do not obtain yet at present effective
It solves.
Refuse gasification technical controlling pollution effects are good, reduced training is significant, resource recovery is high, are that burning is most potential
One of substitute technology, gas-purification, biochemical treatment system are fast-developing at this stage mature, provide well for refuse gasification technology
Subsidiary conditions, strong support is provided to New-type refuse vehicle resource utilization.
Summary of the invention
To overcome problems of the prior art, the present invention provides a kind of domestic waste composite highly effective recyclings
Treatment process.
The technical scheme adopted by the invention to solve the technical problem is that: this kind of domestic waste composite highly effective recycling
Treatment process, including rubbish pretreatment, refuse gasification, purified synthesis gas, biochemical treatment and wastewater treatment, domestic waste warp
Gaseous fuel or liquid fuel are converted into after processing.
Further, inorganic non-toxic solid waste and percolate, solid are isolated in rubbish pretreatment from municipal refuse
Waste is discarded, and percolate passes through subsequent wastewater treatment.
Further, under the hot environment of gasifier that refuse gasification is raw for no dioxin using high-temperature gasification technique
At synthesis gas, the gasification tailings that gasification generates carries out innoxious landfill.
Further, by the purification of the process such as dedusting, desulfurization, the waste water that purification process generates enters subsequent synthesis gas
Wastewater treatment.
Further, purified synthesis gas produces liquid fuel after can entering biochemical treatment unit, and residual gas enters
The burning of fuel gas buring unit, the waste water that biochemical treatment unit generates enters wastewater treatment or purified synthesis gas is directly entered
Fuel gas buring unit.
Further, fuel gas buring unit is equipped with burning boiler, can be used for generating electricity or producing steam, hot water for city
Heating or hot water supply.
Further, liquid fuel passes through liquid fuel clean unit purified treatment.
To sum up, the advantageous effects of the above technical solutions of the present invention are as follows:
Domestic waste produces synthesis gas using high-temperature gasification technique, avoids incineration firing and generates dioxin in the process
Class toxicant.
Liquid fuel, purified rear international sale, liquid fuel valence are produced using biochemical conversion process after purified synthesis gas
Lattice are higher, substantially increase value-added content of product, improve the self-management ability of destructor plant.
According to the energy demand situation on garbage disposal plant area periphery, is burnt using artificial fuel gas and produce electric power, steam or heat
Water improves the production chains of garbage disposal plant area.
The defeated solid residue of off-site and waste realize harmless treatment, it can be achieved that security landfill or making as building materials
With.
Plant area's waste water joint disposal realizes plant area's wastewater zero discharge.
Detailed description of the invention
Fig. 1 is structure of the invention and flow diagram.
Specific embodiment
It is described in detail below in conjunction with 1 pair of attached drawing feature and principle of the invention, illustrated embodiment is only used for explaining this
Invention, is not limited the scope of protection of the present invention with this.
The process flow of the technical solution adopted by the present invention are as follows: domestic waste enters rubbish pretreatment unit, by stone
The solid waste such as block, glass, metal are efficiently separated and are discharged, and remainder is based on organic substance, into rubbish
Fixed bed or moving bed gasifiers can be used in gasification unit, gasifier, and steam or oxygen can be used in gasifying medium, in gasifier
In reducing atmosphere, organic substance and polymer substance are decomposed, and are generated using hydrogen, carbon monoxide as the synthesis gas of predominant gas,
Tailings gasify based on inorganic innocuous substance, innoxious landfill can be carried out.In gasifier, temperature is maintained at 1000 DEG C or more,
Dioxin-like chemical decomposes, and avoids the discharge of dioxin-like chemical in conventional spam burning process.
Synthesis gas enters clean unit, removes pollutants, the purification techniques such as dust, sulphur, the hydrogen chloride in synthesis gas and is
Mature technology, the waste water that clean unit generates enter waste water treatment system.Purified synthesis gas enters biochemical treatment unit,
The burning of fuel gas buring unit can be directly entered.In biochemical treatment unit, microbiological anaerobic fermentation produces first using synthesis gas
The liquid fuels such as alcohol or ethyl alcohol.Biochemical treatment unit waste water enters waste water treatment system, and residual gas enters fuel gas buring unit
Burning.The liquid fuel of biochemical treatment cellular manufacture carries out purifying into liquid fuel clean unit, reaches product standard
Export trade afterwards.
Into the combustion gas of fuel gas buring unit, reach the standard of gas, into burner, combustion product gases reach natural
The discharge standard of gas burning, flue gas can direct emission.Fuel gas buring unit is equipped with gas fired-boiler, can adjust product according to demand,
It can be used for generating electricity, it can also be used to produce steam, hot water is supplied for urban heat supplying or hot water.
Above-described embodiment is only the description that carries out to the preferred embodiment of the present invention, not to the scope of the present invention into
Row limits, without departing from the spirit of the design of the present invention, relevant technical staff in the field to various modifications of the invention and
It improves, should all be included in protection scope determined by claims of the present invention.
