Description
Technical field
The utility model belongs to refuse treatment plant, and in particular to a kind of dry type refuse gasification boiler.
Background technology
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.As the rubbish of city cleaning object, it is handled and whether is rationally not only directly related to people’s lives environment, also can
Potential impact is formed to natural ecosystems.Waste incineration is the widely used Disposal of Municipal Refuse in countries in the world.
Sanitary fill scaffolding phenomenon often occurs for the gasification combustion chamber of existing refuse gasification incinerator, causes gasification, and combustion insufficient,
Fuel combustion supporting, and the burning position dispersion in stove are needed, is easily radiated, temperature is difficult to control, and often occurs not continuing to fire
Burn or be difficult to situation about lighting, the poisonous and harmful element in flue gas is caused not decomposed thoroughly, flue gas can not qualified discharge, make
Into atmosphere pollution.The SO that direct burning process generatesX、NOX, HCl, dust cause atmosphere pollution, in flue gas of refuse burning and flying dust
Hypertoxic organic matter content of dioxin is larger, seriously endangers human health.
Utility model content
It can effectively solve the problems, such as that sanitary fill is put up a shed the purpose of this utility model is to provide one kind, not need to mix fuel and help
The dry type refuse gasification boiler of combustion.
The technical scheme adopted for realizing the purpose of the utility model is as follows：
Dry type refuse gasification boiler provided by the utility model, including furnace body, the top of furnace body is equipped with feeding port and flue gas
Outlet, lower part are equipped with ash hole and air intlet；The centre of furnace body is for pyrolytic gasification reative cell and equipped with gas outlet and flue gas
Recycle entrance；Fume treatment retracting device is equipped between exhanst gas outlet and off-gas recovery entrance.
The fume treatment retracting device is located at the inner cylinder in outer barrel including outer barrel, along axis, is between inner cylinder and outer barrel
Gas channel, outer barrel are equipped with gas inlet and are connected by the exhanst gas outlet of pipeline and wind turbine and furnace body, and the bottom of outer barrel is equipped with row
Dirty mouth；The lower end of inner cylinder is equipped with opening, and upper end is equipped with exhanst gas outlet and is connected by the off-gas recovery entrance of pipeline and furnace body, inner cylinder
It is interior to be equipped with deacidifying flue gas filler；Deacidifying flue gas filler is porous material, and alkaline matter is adsorbed on filler.
The beneficial effects of the utility model
Based on China's house refuse situation not high without classification, calorific value, the utility model is produced using rubbish in burning
Rubbish is dried in raw flue gas recirculation, since the temperature that dry refuse gasification needs is more much lower than the operating temperature of wet refuse,
Therefore the utility model can easily carry out refuse gasification processing, it is therefore prevented that the stench diffusion of rubbish can also obtain combustibility
Air source is conducive to garbage as resource processing.
The utility model does not need to mix fuel combustion supporting, and due to not setting burner in furnace body, rubbish does not have in burning
There is blocking, can effectively solve the problems, such as that sanitary fill is put up a shed.The utility model disposes rubbish using pyrolysis gasification method, is a kind of phase
The more environmentally friendly method for garbage loading embeading and burning method.The combustion gas that refuse gasification generates stores after purification, calorific value
It in 1200 kilocalories or so, generates electricity available for gas electricity generator, the combustion gas that experiment shows to generate after refuse gasification processing is sent out
3 times of electricity higher than traditional waste incineration and generating electricity 2.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
See Fig. 1, dry type refuse gasification boiler provided by the utility model, including furnace body 3, the top of furnace body 3, which is equipped with, to feed intake
Mouth 4 and exhanst gas outlet 5, lower part are equipped with ash hole 1 and air intlet 9；Pyrolytic gasification reative cell 2 is in the centre of furnace body 3 and is equipped with
Gas outlet 7 and off-gas recovery entrance 8 are equipped with fume treatment retracting device 6 between exhanst gas outlet 5 and off-gas recovery entrance 8；Cigarette
The inner cylinder 603 that gas disposal retracting device 6 includes outer barrel 604, is located at along axis in outer barrel 604, between inner cylinder 603 and outer barrel 604
For gas channel 607, outer barrel 604 is connect equipped with gas inlet 601 by pipeline and wind turbine 608 with the exhanst gas outlet 5 of furnace body 3,
The bottom of outer barrel 604 is equipped with sewage draining exit 606；The lower end of inner cylinder 603 is equipped with opening, and upper end passes through pipeline equipped with exhanst gas outlet 602
It is connect with the off-gas recovery entrance 8 of furnace body 3, deacidifying flue gas filler 605 is equipped in inner cylinder 603；Deacidifying flue gas filler 605 is porous
Material is adsorbed with alkaline matter on filler 605.
Technological process：A small amount of rubbish is first being lighted into input furnace body 3, then by rubbish to be processed by feeding port with ignition substance
The pyrolytic gasification reative cell 2 of 4 input furnace bodies 3, rubbish moves down under gravity in combustion, since flue gas follows
The heat effect of ring, the temperature of pyrolytic gasification reative cell 2 are stepped up until refuse pyrolysis is gasified, and air is by air blower through sky
Gas import 9 enters furnace body 3, and oxygen is provided for incineration firing pyrolytic gasification.Pyrolysis smoke is passed through by the exhanst gas outlet 5 on furnace body 3

The dust in flue gas is removed with centrifugal principle, the flue gas after dedusting contains certain acidic materials HCl, tar and moisture, contains
Acid, tar and moisture flue gas enter through deacidifying flue gas filler 605 from 603 lower end of inner tube, the tar in flue gas is by flue gas
Depickling filler 605 intercepts absorption, and neutralization reaction then occurs with the alkaline matter in deacidifying flue gas filler 605 for acidic materials, removes
After going HCl, tar and partial moisture, the off-gas recovery entrance 8 on exhanst gas outlet 602 and furnace body 3 of the flue gas through inner cylinder 603 enters
The pyrolytic gasification reative cell 2 of furnace body 3, and pyrolytic gasification reaction is participated in, provide vapor for pyrolytic gasification；Flue gas ash removal depickling is produced
Raw tar, water and cigarette ash is discharged together by the sewage draining exit 606 on outer barrel 604.The lime-ash that pyrolytic gasification reative cell 2 generates is from going out
Grey mouth 1 is discharged, and pyrolysis gas is discharged by gas outlet 7.Pyrolysis gas removes the heavy metal steam in pyrolysis gas through gas-purification system
Fuel power generation function can be used as with chlorine, sulfide or provides the energy for other industrial productions.
