Description
Technical field
The invention belongs to refuse treatment plant, and in particular to a kind of dry type refuse gasification boiler.
Technical background
With the progress of human society, the raising of civilization degree, urban population constantly increases, domestic waste also with day
It is all to increase.The rubbish of object is cleared up as city, whether living environment for being rationally not only directly connected to people is processed it, also can
Potential impact is constituted to natural ecosystems.Waste incineration is the widely used Disposal of Municipal Refuse in countries in the world.
Often there is sanitary fill scaffolding phenomenon in the gasification combustion chamber of existing refuse gasification incinerator, cause gasification, and combustion insufficient,
Need the burning position in fuel combustion supporting, and stove to disperse, easily radiating, temperature is difficult to control to, often occur to continue to fire
Burn or be difficult to situation about lighting, cause the poisonous and harmful element in flue gas thoroughly to be decomposed, flue gas cannot qualified discharge, make
Into atmosphere pollution.The SO that direct burning process is producedX、NOX, HCl, dust cause atmosphere pollution, in flue gas of refuse burning and flying dust
Hypertoxic organic matter content of dioxin is larger, serious harm human health.
The content of the invention
Sanitary fill scaffolding problem can be effectively solved it is an object of the invention to provide one kind, it is not necessary to mix fuel combustion supporting
Dry type refuse gasification boiler.
Realize that the technical scheme that the object of the invention is used is as follows：
The dry type refuse gasification boiler that the present invention is provided, including body of heater, the top of body of heater is provided with dog-house and exhanst gas outlet, bottom
It is provided with ash hole and air intlet；The centre of body of heater is pyrolytic gasification reative cell and is provided with gas outlet and off-gas recovery entrance；
Fume treatment retracting device is provided between exhanst gas outlet and off-gas recovery entrance.
The fume treatment retracting device includes outer barrel, the inner cylinder being located at along axis in outer barrel, is between inner cylinder and outer barrel
Gas channel, outer barrel is provided with gas approach and is connected with the exhanst gas outlet of body of heater by pipeline and blower fan, and the bottom of outer barrel is provided with row
Dirty mouth；The lower end of inner cylinder is provided with opening, and upper end is provided with exhanst gas outlet and is connected with the off-gas recovery entrance of body of heater by pipeline, inner cylinder
Inside it is provided with deacidifying flue gas filler；Deacidifying flue gas filler is porous material, and alkaline matter is adsorbed with filler.
Beneficial effects of the present invention
Do not classified based on China's house refuse, the situation that calorific value is not high, the present invention using rubbish burning produce flue gas
Circulation is dried to rubbish, because the temperature that dry refuse gasification needs is more much lower than the operating temperature of wet refuse, therefore this hair
It is bright easily to carry out refuse gasification treatment, it is therefore prevented that the stench diffusion of rubbish, flammable source of the gas can also be obtained, be conducive to rubbish
Rubbish recycling treatment.
The present invention need not mix fuel combustion supporting, and due to not setting burner in body of heater, rubbish does not hinder in burning
Gear, can effectively solve sanitary fill scaffolding problem.Present invention use pyrolysis gasification method disposal rubbish is one kind relative to rubbish
More environmentally friendly method for landfill and burning method.The combustion gas that refuse gasification is produced after purification by storing, and its calorific value is big 1200
Card left and right, can be used for gas electricity generator generating, and experiment shows, the combustion gas produced after refuse gasification treatment generate electricity than traditional rubbish
3 times of rubbish burning electricity generation high 2.
Technical scheme is further illustrated below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
See Fig. 1, the dry type refuse gasification boiler that the present invention is provided, including body of heater 3, the top of body of heater 3 is provided with the He of dog-house 4
Exhanst gas outlet 5, bottom is provided with ash hole 1 and air intlet 9；The centre of body of heater 3 is pyrolytic gasification reative cell 2 and is provided with combustion gas and goes out
Mouth 7 and off-gas recovery entrance 8, are provided with fume treatment retracting device 6 between exhanst gas outlet 5 and off-gas recovery entrance 8；Fume treatment
Retracting device 6 includes outer barrel 604, the inner cylinder 603 being located at along axis in outer barrel 604, is air-flow between inner cylinder 603 and outer barrel 604
Passage 607, outer barrel 604 is provided with gas approach 601 and is connected with the exhanst gas outlet 5 of body of heater 3 by pipeline and blower fan 608, outer barrel 604
Bottom be provided with sewage draining exit 606；The lower end of inner cylinder 603 is provided with opening, and upper end is provided with exhanst gas outlet 602 by pipeline and body of heater 3
Off-gas recovery entrance 8 connect, is provided with deacidifying flue gas filler 605 in inner cylinder 603；Deacidifying flue gas filler 605 is porous material, is filled out
Alkaline matter is adsorbed with material 605.
Technological process：A small amount of rubbish is first being lighted into input body of heater 3 with ignition substance, then by rubbish to be processed by dog-house
The pyrolytic gasification reative cell 2 of 4 input bodies of heater 3, rubbish moves down under gravity in combustion, because flue gas is followed
The heat effect of ring, the temperature of pyrolytic gasification reative cell 2 is stepped up until refuse pyrolysis are gasified, air is by air blower through sky
Gas import 9 enters body of heater 3, for incineration firing pyrolytic gasification provides oxygen.Pyrolysis smoke is passed through by the exhanst gas outlet 5 on body of heater 3
Blower fan 608 carries out dedusting depickling treatment into fume treatment retracting device 6, and the pyrolysis smoke from body of heater tangentially enters
Outer barrel 604 in fume treatment retracting device 6, the gas channel rapid spiral between outer barrel 604 and inner cylinder is moved downward, profit
The dust in flue gas is removed with centrifugal principle, the flue gas after dedusting contains certain acidic materials HCl, tar and moisture, contains
The flue gas of acid, tar and moisture enters through deacidifying flue gas filler 605 from the lower end of inner tube 603, and the tar in flue gas is by flue gas
Depickling filler 605 intercepts absorption, and acidic materials then occur neutralization reaction with the alkaline matter in deacidifying flue gas filler 605, remove
After removing HCl, tar and part moisture, flue gas enters through the off-gas recovery entrance 8 on the exhanst gas outlet 602 and body of heater 3 of inner cylinder 603
The pyrolytic gasification reative cell 2 of body of heater 3, and pyrolytic gasification reaction is participated in, for pyrolytic gasification provides vapor；Flue gas ash removal depickling is produced
Raw tar, water and cigarette ash are discharged by the sewage draining exit 606 on outer barrel 604 together.The lime-ash that pyrolytic gasification reative cell 2 is produced is from going out
Grey mouth 1 is discharged, and pyrolysis gas are discharged by gas outlet 7.Pyrolysis gas remove the heavy metal steam in pyrolysis gas through gas-purification system
With chlorine, sulfide can be as fuel power generation function or for other industrial productions provide the energy.
