Abstract
The utility model discloses an oxygen-enriched local oxygen-increasing jet auxiliary combustion device for an incinerator. According to the device, a high-temperature flue gas formed by combusting a gas fuel or a liquid fuel by utilizing local oxygen-increasing oxygen-enriched auxiliary combustion and a mist flow formed by jetting incinerated waste liquid or waste gas are mixed so that the waste liquid or the waste gas is subjected to thermal oxidation reaction. The device is characterized in that the temperature of the highest temperature area of a flame is improved by combusting the gas fuel or the liquid fuel by utilizing the local oxygen-increasing oxygen-enriched auxiliary combustion; the difference value obtained by subtracting the radius of a combustion flame and the radius of the mist flow area formed by jetting the incinerated waste liquid or waste gas from the distance between the central point of the highest temperature area of the combustion flame and the central point of the mist flow area formed by jetting the incinerated waste liquid or waste gas is 0 to 1,000 MM; and however, in actual operation, the situation that the outer edge of the combustion flame is close to the edge of the mist flow area formed by jetting the incinerated waste liquid or waste gas is the best.
Description
Technical field
The present invention relates to the local oxygen-enriched oxygenation jet combustion supporting of incinerator device, be applicable to variously take liquid or gas as the burning waste liquid of fuel or the incinerator of waste gas, belong to oxygen-enriched combustion-supporting and incineration technology field.
Background technology
There are a lot of chemical plant to produce aborning waste liquid or waste gas can't be processed, it need to be carried out high temperature incineration and be decomposed into nontoxic composition, the high temperature incineration process is actually and makes waste liquid or waste gas at high temperature carry out thermal oxidative reaction, rather than directly waste liquid or waste gas are burnt, that is to say, the burning of waste liquid or waste gas be since a large amount of high-temperature flue gas that the burning of fuel produces by heat radiation and convection current double action, heat is delivered in the waste liquid or waste gas that is burned, make it that oxidation reaction at high temperature occur, so how to improve to greatest extent the temperature of incineration area and be the key that improves its waste liquid or burned waste gas decomposition efficiency, the efficient that improves incineration area has two kinds of methods: a kind of be utilize oxygen-enriched combustion-supporting and use uncle minister in ancient times's Wei patented technology " 201110270536.1 are used for the fuel-firing gas-firing oxygen enrichment multifuel combustion nozzle of local oxygen-enriched oxygenation jet combustion supporting " and " the multifuel combustion nozzle of 201120342769.3 fuel-firing gas-firings and local oxygen-enriched oxygen enriching burning-aid " thus directly improve temperature raising waste liquid or the burned waste gas efficient of combustion flame; Another kind is to improve waste liquid or burned waste gas efficient by the combustion flame high-temperature region of regulating incinerator and the distance of incineration area.
Summary of the invention
The purpose of this invention is to provide a kind of oxygen-enriched combustion-supporting that utilizes and improve the local oxygen-enriched oxygenation jet combustion supporting of the incinerator device that combustion flame temperature and the combustion flame high-temperature region by regulating incinerator and the distance of incineration area improve burning waste liquid or waste gas efficient.
The local oxygen-enriched oxygenation jet combustion supporting of incinerator device, comprise that gaseous fuel or liquid fuel utilize the high-temperature flue gas of local oxygen enriching oxygen-enriched combustion-supporting burning formation to mix with the spray that is burned the formation of waste liquid or exhaust blast and make waste liquid or waste gas heat oxidation reaction, it is characterized in that:
1, gaseous fuel or liquid fuel improve the temperature in peak flame temperature district by the burning of local oxygen enriching oxygen-enriched combustion-supporting, distance between the spray district center point that the central point of combustion flame highest temperature zone and quilt burning waste liquid or exhaust blast form, deduct the radius of combustion flame, deduct by the spray district radius of burning waste liquid or exhaust blast formation again, its difference is 0 ~ 1000MM, but is to be close as the best with the outward flange of combustion flame and by the spray area edge of burning waste liquid or exhaust blast formation in practical operation.
2, combustion flame and burned spray district that waste liquid or exhaust blast form and try not overlappingly, because overlapping meeting reduces flame temperature, flame temperature reduces and just equals to reduce the firing efficiency that fuel combustion forms.
3, when the flame diameter of fuel combustion is more much larger than the spray district diameter that is burned the formation of waste liquid or exhaust blast, the central point of combustion flame highest temperature zone can be slightly larger with the distance of the spray district center point that is burned the formation of waste liquid or exhaust blast, but the most very much not should surpass 1000MM.
4, when the flame diameter of fuel combustion less when a lot of than being burned spray district diameter that waste liquid or exhaust blast form, the central point of combustion flame highest temperature zone is as small as possible with the distance of the spray district center point that is burned the formation of waste liquid or exhaust blast, but minimum should be less than 0MM.
5, this method is applicable to be burned the zone that high-temperature flue gas that spray district that waste liquid or exhaust blast form forms in burning is flowed through, if the zone that the high-temperature flue gas that the spray district that quilt burning waste liquid or exhaust blast form or not in burning is flowed through, that is to say that being burned waste liquid or waste gas relies on the heat radiation oxidation Decomposition fully, no matter how burned the direction of the product direction of motion that waste liquid or off-gas oxidizing decompose and the smoke movement of fuel combustion, the central point of combustion flame highest temperature zone all should be greater than 600MM with the distance of the spray district center point that is burned the formation of waste liquid or exhaust blast.
6, the local oxygen-enriched oxygenation jet combustion supporting of incinerator device comprises the liquid fuel spray gun or the gaseous fuel spray gun that are installed on the incinerator wall, and is installed in the nearer waste liquid spray gun of incinerator wall and liquid fuel spray gun or gaseous fuel spray gun or waste gas spray gun; Liquid fuel spray gun or gaseous fuel spray gun relatively waste liquid spray gun or waste gas spray gun are done certain displacement and/or angular adjustment, and perhaps liquid fuel spray gun or gaseous fuel spray gun are done certain displacement and/or angular adjustment relatively for waste liquid spray gun or waste gas spray gun; The combustion flame of formation certain diameter after Fuel lance is lighted, waste liquid spray gun or waste gas lance ejection waste liquid or waste gas form certain spray district simultaneously, the position of fuel metering spray gun is or/and angle, and the outward flange that makes combustion flame is that oxygen-enriched combustion-supporting burns optimum position and angle with burning that spray area edge that waste liquid or exhaust blast form is close; Perhaps regulate the position of waste liquid spray gun or waste gas spray gun or/and angle, it is oxygen-enriched combustion-supporting burning optimum position and angle that the outward flange that is burned spray area edge that waste liquid or exhaust blast form and combustion flame is close.
The present invention compared with prior art has the following advantages:
1, the present invention is by utilizing Wei uncle minister in ancient times patent nozzle to make combustion flame obtain higher combustion flame highest temperature zone, thereby increases combustion flame to burning the radiation efficiency of waste liquid or waste gas.
2, the present invention is by regulating combustion flame highest temperature zone and the distance of being burned the spray district that waste liquid or exhaust blast form, thereby makes the more effectively radiation spray district that burned waste liquid or exhaust blast and form of combustion flame highest temperature zone.
