First citing description in the related technology the pyrolysis processing technology of house refuse and the problems of.
A kind of urban refuse thermal decomposition processing method of the patent disclosure of Patent No. 200810122703.6.This method is first
By municipal refuse by sorting, the high substance of Plastic chlorine-containing component is eliminated, and derivatived fuel is made.It then can using high temperature
Combustion gas body is dried rubbish, is pyrolyzed, the biological fuel gas that high-temperature fuel gas is generated from agriculture and forestry organic waste material pyrolytic gasification.Dress
There is the gas in the container of municipal refuse to be discharged from gas outlet, and the completely burned in gas combustion furnace.Gas burning furnace exhaust gas
Through over-quenching, it is cooled to 200 DEG C or less discharges.
The processing mode has the following problems:
In order to reduce the predecessor (such as polyvinyl chloride, polychlorostyrene resin) for generating dioxin, using sorting process, although
Chlorine-bearing compound is reduced, but equally reduces the content of H in material, H in the pyrolysis gas of acquisition2Less, pyrolysis gas calorific value is lower,
Recycling level is not high.Belong to the environment of anaerobic or anoxic in itself due to being pyrolyzed, generated substantially without dioxin under reducing condition,
Therefore sorting process bring effect is not obvious.
Drying garbage, pyrolysis the combustible gas that is generated from another agriculture and forestry organic waste material pyrolysis gasifying device of heat source, due to
Energy loss, pyrolysis temperature is lower, therefore can generate part pyrolysis oil, and the utilization of pyrolysis oil and processing are more difficult, will affect
The continuous operation of entire technique, and two pyrolysis installation collaborative process its economic benefits are poor, and dry bring exhaust gas volumn is big,
Processing cost is high.

A kind of refuse pyrolysis gas purification process of power generation by gas of the patent disclosure of Patent No. 201210282640.7,
Route is that house refuse passes through broken, drying, granulated garbage is made in extrusion granulation；Granulated garbage is 600 DEG C or so in pyrolysis oven
Anoxic thermal decomposition generates raw gas；High temperature rough gas recycles thermal energy into heat exchanger, and progress flue gas is net after raw gas is cooled to low temperature
Change, then dedusting, abjection tar；Then the substances such as sour gas, dioxin are removed；Last clean coal gas pushing away in air-introduced machine
Dynamic lower progress direct combustion power generation.
The processing mode has the following problems:
Preprocessing process is complicated, due to, containing there are many metal, cloth bag, being easy to have an impact crushing device in rubbish, because
This device continuous operation effect is bad, and the material after extrusion granulation is since density is big, mass-and heat-transfer is slow, pyrolysis oil in pyrolytic process
Yield can improve, pyrolysis gas yield can decline, be unfavorable for subsequent power generation utilization.
The temperature of pyrolysis oven is 600 DEG C ± 50 DEG C, belongs to middle low temperature pyrogenation, conducive to the output of pyrolysis oil, gas yield compared with
It is low, the processing cost of impurity (sour gas, tar etc.) is increased, economic benefit is unobvious.
To sum up, in the related technology the generally existing deficiency in economic performance of domestic garbage pyrolysis processing technique, recycling level are not
The problems such as industrial applications high, difficult to realize.

Heat.Oil gas vent is set in pyrolysis zone end furnace body upper end, refuse pyrolysis gas-liquid mixture is discharged.End furnace body bottom
Discharge port is arranged in portion, and refuse pyrolysis charcoal is discharged, pyrolytic carbon has certain combustion heat, belongs to the energy product of low heat value,
It is subsequent to gasify, it obtains gasification gas and is continued to use as the fuel of pyrolysis oven.
For the high-temperature oil gas that refuse pyrolysis generates, it is fed directly to pyrolysis oil qi exhaustion chlorine equipment 30 and carries out high temperature dechlorination,
And then it is sent into direct combustion power generation device 40, it is defeated outside the progress of institute's electricity to sell.
In some embodiments of the invention, pass through double helix discharging machine between pyrolysis plant 20 and palletizing device 50
It is connected.
Wherein, in balling process, the pyrolytic carbon partial size come out from pyrolysis plant 20 is too small, after pellet forming process,
Partial size is increased to 10mm-20mm, then is sent into gasification installation 60 together with coal is mended.
Optionally, gasification installation 60 is recirculating fluidized bed.
Pyrolytic carbon becomes the larger particle of partial size after pellet forming process, and mends coal and be sent into the progress of gasification installation 60 together
Gasification, 850-950 DEG C of gasification temperature, and all dust Controls in gasification installation 60, so that melting becomes clinker, it is then outer
Fortune landfill, obtained gasification gas are passed through pyrolysis oven by gasification gas transfer pipeline 70, use for the heating of pyrolysis plant 20, very
Just realizing the minimizing of rubbish, innoxious and recycling treatment.
Citing describes the specific of domestic garbage pyrolysis charcoal gasification process system and method according to an embodiment of the present invention below
Process.
Use certain city's house refuse for raw material, msw water content about 52%, at being grouped as such as table 1:
1 house refuse of table is at being grouped as (wt%)
Pretreatment: house refuse is sent to pre-processing device 10 through transportation system, sorts out bulk inorganic matter therein, such as brick
Head, stone, big part glass metal product etc.；
Pyrolysis: pyrolysis plant 20 includes solution furnace, the auxiliary bodies such as radiant tube burner, cloth and discharging.The furnace of pyrolysis oven
Bottom is rotatable ring-shaped furnace bottom, and radiant tube burner is arranged in annular furnace wall, through burn combustible gas in a manner of heat radiation
Refuse pyrolysis institute calorific requirement is provided, the atmosphere isolation in the flue gas and pyrolysis oven in radiant tube burner.Pyrolysis oven is divided into two
A region is dry section and pyrolysis zone respectively, and 340-360 DEG C of dry section temperature, main function is to carry out the moisture in rubbish
Drying, 730-750 DEG C of pyrolysis zone temperature are that rubbish completes pyrolysis main reaction region, and reaction generates pyrolysis oil gas and pyrolytic carbon, in heat
It solves furnace roof portion and oil gas vent is set close to pyrolysis zone, for collecting the high temperature pyrolysis of oil and gas containing water vapour；
Pelletizing: the pyrolytic carbon of generation is discharged using sealing double helix discharging machine and is sent into palletizing device 50, and double helix is side by side
Setting, spiral is engaged, and since rubbish have passed through pyrolytic reaction, plastics therein, fabric, the organic matters such as wood bamboo, which are pyrolyzed, is
Carbide, which is different from crude waste, loose easily broken, by the stirring of double helix, squeezing action, is pyrolyzed carbon granule
Diameter becomes smaller, and by pelletizing, partial size is increased to 12mm-15mm；
Gasification: the pyrolytic carbon particle after pelletizing enters gasification installation 60, generates gasification gas through gasification, sets for pyrolysis
Standby 20 use, and the slagging in gasification installation 60 of all dust is discharged；
Dechlorination power generation: high temperature pyrolysis of oil and gas are passed through direct combustion power generation device 40 after passing through pyrolysis oil qi exhaustion chlorine equipment 30, are sent out
Electric power is outer defeated to sell in addition to personal.
Domestic garbage pyrolysis charcoal gasification process system and method according to an embodiment of the present invention, in conjunction with refuse pyrolysis technique,
The technologies such as pelletizing technology, direct combustion power generation have thoroughly carried out minimizing, harmless treatment to house refuse, and have not expended the external world
Energy, solve the problems such as pyrolytic carbon is difficult to gasification process, possessing high-temperature oil gas, to have carried out environmental benefit after dechlorination good etc. excellent
Gesture has good economic benefit.
