Description
Technical field
It can suppress to produce CO, hydrocarbon etc. during burning domestic garbage, trade waste the present invention relates to one kind
Unburned thing and the refuse burning system for producing bioxin.
Background technology
At present, in most of rural area and Small Urban, largely there is rubbish and throw out the behavior of leaving about without care, the pollution of rubbish has resulted in
Influence to living environment, because rural area and Small Urban lack the facility that rubbish is uniformly processed extensively, villager is mostly outdoor
Voluntarily burn away the refuse, bring the secondary pollution to environment and occur the hidden danger of unexpected fire, make at present in rural area and Small Urban
Waste incinerator generally existing is difficult to clear up, and burns insufficient, not exclusively, big for environment pollution in combustion process, it is difficult to
The problems such as persistently use.
Burning disposal of the rubbish by modernization, volume can typically reduce 80%~90%, while various diseases can be eliminated
Substance, harmless object is converted into by harmful substance, can also realize the utilization of recycling, waste incineration be realize garbage decrement,
One of main path of innoxious and recycling treatment.
Waste incineration turns into one of main path of current garbage disposal, using mechanical more than the existing waste incineration of China
Waste incinerator, for example, CN104613481A disclose a kind of waste incinerator there is provided waste incinerator be in lateral arrangement,
Combined in the horizontal by some mobile units, some mobile units are integrally supported by support meanss and driven by same
Dynamic device is driven.Effectively solve pusher dolly it is stuck the problem of, while so that distribution of the house refuse on fire grate more
Uniformly, combustion efficiency is improved.
In the prior art, most waste incinerators include charging aperture, feed fire grate, are used for waste incineration in burner hearth
Fire grate, positioned at First air air feed system, the Secondary Air air feed system and slag extractor positioned at furnace throat portion for burning fire grate bottom.
Burning fire grate is monolithically fabricated the siege for burning away the refuse, and siege edge is longitudinally divided into dryer section, burning zone and after-flame section, incinerator
Row is overall along multiple burning units are longitudinally divided into, usually 5 units, each burning unit by multiple slip fire grate segments, stir
Fire grate segment and fixed grate film composition.Rubbish pours into waste incinerator from charging aperture, by the reciprocal impetus for being fed fire grate
Rubbish enters to be burned on the siege in incinerator, is oven-dried in dryer section rubbish, is dehydrated, and rubbish is mainly in burning zone progress
Burning, the rubbish by after-flame section has burnt totally, and remaining clinker enters slag extractor afterwards, is discharged out of the furnace by slag extractor.
Wherein First air is from the air compartment feeding for burning fire grate bottom, and Secondary Air is sent into from the furnace throat portion of waste incinerator.Existing rubbish
Incinerator (industrial furnace), during burning away the refuse, the bad control of ignition point, burning process control is not accurate enough, burning
It is insufficient, pernicious gas is inevitably generated, such as nitrogen oxides He bioxin, these pernicious gases are to environment and human body
It is very harmful.
MSW heating value is relatively low.For example engineering design calorific value in part is in 1450kcal/kg or so.Large-scale incinerator and with
The stove of other fuel mixed combustions preferably can more fully hereinafter burn house refuse, and operating cost still receives, to ring
The secondary pollution in border is smaller.However, because being influenceed by the factor such as refuse collection and transport, in plurality of Small Urban and township
Village, it is impossible to handle house refuse using large-scale incinerator, is only capable of handling house refuse using simple waste incinerator.Burn
It is insufficient, not exclusively, auxiliary fuel need to be largely used, input and operating cost are higher, it is difficult to persistently use.For simply burning
Burn for stove, in combustion, imperfect combustion easily occurs for the house refuse of low heat value, a large amount of unburnts are with catching fire
Flame and burning gases rise, due to there is substantial amounts of bioxin predecessor in unburned part, so in burning and gas-exhausting
The very strong bioxin of toxicity is generated, is discharged into air, in addition, the discharge capacity of other pollutants is also more.Thus exploitation is substituted
The same category of device of simple waste incinerator in the prior art, with realistic meaning.
The content of the invention
In order to overcome the defect of prior art, the present invention provides a kind of CIU for being used to handle rubbish, existing to solve
Have waste incinerator during combustion refuse, because burn it is insufficient produce too much CO, the unburned thing such as hydrocarbon and

Operation principle：
Provided with drying garbage storehouse, the hot gas of the second combustion chamber 5 enters drying garbage storehouse through smoke-collecting apparatus 9, the first flue 10
It is interior, the rubbish in drying garbage storehouse is dried, the temperature of rubbish in the first combustion chamber 4 is lifted into, containing for rubbish is reduced
Water rate, and make moisture content stable.The hot gas in drying garbage storehouse derives from the second combustion chamber 5, passes through the negative pressure of the second flue 12
Attract or air blower enters drying garbage storehouse through the first flue 10, the second combustion chamber 5 passes through the second First air tuyere the 18, the 2nd 2
Secondary wind tuyere 19 supplements air.Flue gas is after cooler 30 further cooling, and removing dust device 31 and clarifier 32 are purified, through air inducing
Machine 28 and chimney 29 are discharged, and air-introduced machine 28 and chimney 29 can make to keep negative pressure in combustion furnace, improve operating environment.
Some air vents are provided with engine firewall 22, network structure is formed, hot gas is heated to the rubbish in drying garbage storehouse
Afterwards, hot gas and the water vapour being evaporated can enter the second flue 12 by engine firewall 22, discharge out of the furnace, make through induced draught system
The air vent of engine firewall 22 has certain gas flow rate during industry, engine firewall 22 is prevented the burning particles in the second flue 12
Thing is fallen into drying garbage storehouse, and the engine firewall 22 of network structure can also prevent the drift flown out out of drying garbage storehouse from entering
In two flues 12, influence of the disturbance to production of air-flow can be reduced.The discharging opening of feeder 25 is connected with material-feeding mechanism 26, cloth
Material mechanism 26 makes rubbish be evenly distributed on fire grate 6, makes the quantity of refuse entered in the first combustion chamber 4 stable, beneficial to burning process
Stabilization.
Sealing mechanism 17 is provided between the discharging opening of material-feeding mechanism 26 and the first combustion chamber 4, on the one hand, pass through sealing mechanism
17 air blowing, makes to maintain a higher malleation at the charging aperture of the first combustion chamber 4, the flare in the first combustion chamber 4 is not entered
Enter material-feeding mechanism 26, in case part rubbish prematurely ignition, is relatively fixed ignition point during incineration firing；On the other hand,
Material-feeding mechanism 26 is cooled, the service life of extension device makes the combustibles in rubbish will not be prematurely in material-feeding mechanism
Ignition in 26, reduces the generation of unexpected fire.
Air preheater 13 may be provided at top or the sidepiece of body of heater 1, and preferably scheme is provided in the top of body of heater 1
After position more than portion and sidepiece secondary tuyere, cool exterior air air inlet preheater 13, pass through cold air quilt after heat exchange
Heating；Continue to be heated subsequently into air heater 14, the hot-air after heating is after the pressurization of the first air blower 23 through first
First air tuyere 15, the first Secondary Air tuyere 16, sealing mechanism 17 enter in the first combustion chamber 4, through the second First air tuyere 18
