Description

Pyrolysis formula incinerator

The utility model relates to a kind of, with the small-sized rubbish incinerator that pyrolysis way is burnt away the refuse, is mainly used in the rubbish that burns medical treatment, laboratory, factory, school.

At present, the small-sized rubbish incinerator on the market, great majority serve as to form with reference to improving with industrial furnace or coal-burning boiler.It is simple in structure, there is not secondary combustion chamber, rubbish in the stove when initial the burning because its water content is big, be difficult for spontaneous combustion so ignition temperature is lower, do not have the automatic air supply device rubbish can not completing combustion again, cause the generation of a large amount of black smokes, lack suitable effective flue gas processing device simultaneously, the flue gas of discharging does not reach discharging standards, causes serious secondary pollution to surrounding environment.Particularly medical treatment and breadboard garbage waste material are owing to the residue, spoil that contain a large amount of infective virus and various organic medicament and reagent etc.Incineration temperature virus inadequately can't all kill, and various organic matters and spoil also can produce stench, does not have enough temperature dioxin also can't eliminate.Therefore the small-sized rubbish incinerator on the market can not use at present mostly, or result of use is poor, and the heat that burns the back generation in addition can not reclaim a large amount of heats and be wasted.

The purpose of this utility model provides a kind of, and refuse pyrolysis is burned and be provided with start-up burner, air supply device, secondary combustion chamber, deduster and waste heat receiving system, the small-sized rubbish incinerator of emission of smoke tallies national standard.

The purpose of this utility model is this realization, rubbish in the primary zone by ignition, by the heat that self produces, the primary combustion room temperature is remained on 600-700 ℃, and the wind supply quantity of controlling a pressure fan is anaerobic condition, rubbish decomposes under 600-700 ℃ high temperature, carbonization, produces great number of flammable gas.Rubbish after the carbonization burns away in that primary combustion is indoor, and the flue gas that imflammable gas and primary zone produce is admitted to secondary combustion chamber.Imflammable gas with after auxiliary air that second blower is sent into mixes, is lighted by secondary burner in secondary combustion chamber.Gas generation high temperature after the burning remains on 900-1000 ℃ with the temperature of secondary combustion chamber, is decomposed at the indoor various viruses of second-time burning, dioxin and stench, and black smoke is by after-flame.The flue gas of discharging from secondary combustion chamber is odorless, smokeless, harmless high-temperature gas.High-temperature gas enters waste-heat recovery device again is recovered 85% heat, the flue-gas temperature that waste-heat recovery device is discharged drops to 200-250 ℃, waste-heat recovery device is with the outside heat supply of the pattern of hot water, part heat is converted to cold cooling storehouse through the absorption refrigeration unit and uses, and a part of heat also can use for life and heating.Flue gas through spray type dust separator and fiber bag precipitator, discharges out of the furnace after the dedusting again, and the gas of discharge is for smokeless, odorless, free of contamination cryogenic gas and conform to national every emission standard.

Because the heat that has adopted such scheme, the standard limit of smog release of pyrolysis formula incinerator to be better than national standard and can to recycle incinerator in a large number and produced.

Below in conjunction with drawings and Examples utility model is further specified.

Accompanying drawing is a principle system diagram of the present utility model.

No. 3. pressure fans of No. 2. start-up burners in 1. primary zones 4. secondary combustion chambers 5. regnition burners 6. second blowers 7. waste-heat recovery devices 8. spray type dust separators 9. storage cisterns 10. air-introduced machines 11. fiber bag precipitators 12. domestic hot-water's water storage tanks 13. absorption freezers among the figure

In the drawings, rubbish is loaded into primary zone 1, and the primary zone is made by refractory material, insulation material, framework and shell.Rubbish is lighted by start-up burner 2 and is taken fire, and pressure fan 3 send certain air quantity to primary combustion is indoor, and rubbish is burnt under anaerobic condition.Produce a large amount of heats behind the indoor incineration firing of primary combustion, the primary combustion room temperature is improved and remain on 600-700 ℃, the organic matter of rubbish is decomposed at this moment, and the rubbish after the decomposition can produce imflammable gas and carbonization rubbish.Carbonization rubbish is indoor in primary combustion, and burning away provides heat for the combustion chamber.Imflammable gas is admitted to secondary combustion chamber 4, and secondary combustion chamber also is to be made by refractory material, insulation material, framework and shell.After imflammable gas enters secondary combustion chamber, lighted a fire, and do super oxygen burning, make the temperature raising of secondary combustion chamber and remain on 900-1000 ℃ with a large amount of auxiliary airs that second blower 6 is sent into by regnition burner 5.Because the temperature of secondary combustion chamber is very high, the virus, stench, dioxin and the various organic matter that enter in the secondary combustion chamber flue gas are decomposed, carbon in the black smoke is by after-flame, so the secondary combustion chamber flue gas of discharging is nontoxic, odorless, free of contamination high-temperature gas.High-temperature gas enters waste-heat recovery device 7 again, the waste heat heat reclamation device is a kind of waste heat boiler of waterpipe type structure, and high-temperature gas has 85% heat to be recovered utilization when the waste-heat recovery device, water temperature can reach 90-100 ℃, and flue-gas temperature drops to 200-250 ℃.Heated water is passed to absorption freezer 13 by pipeline with heat, and absorption freezer is to adopt the aqua-ammonia absorption-type refrigerating machine principle, and the low-temperature cold store of making, temperature of ice house can reach-5 ℃～-10 ℃.The high-temperature-hot-water of waste-heat recovery device also can be sent into domestic hot-water's water storage tank 12, is outwards supplied the domestic hot-water or is used for heating by water storage tank.Flue gas by the waste-heat recovery device discharge, be admitted to spray type dust separator 8, spray type dust separator is by the downward shower water in top, flue gas is upwards done reverse flow with water by the bottom, dust in the flue gas is taken away by water, water enters storage cistern 9 by the delivery port of spray type dust separator bottom, and the water in the storage cistern can recycle use.For further improving dust removing effects, after the flue gas of spray type dust separator is washed again by air-introduced machine 10, send into fiber bag precipitator 11, fiber bag precipitator is to adopt the high-density non-woven fabrics filter screen to make, can make more high-precision dust removal process to flue gas, make the every index of the flue gas that enters atmosphere all meet national standard.Air-introduced machine 10 is negative pressure requirements of control body of heater, waste-heat recovery device and spray type dust separator, also is the blower fan that positive pressure pressure is provided for fiber bag precipitator.
