Abstract
The utility model discloses a rotary kiln type fly ash reburning device, which relates to a combustion device of fly ash which contains harmful residue which is generated after garbage is burnt. The device aims at the characteristics such as small fly ash granules, poor ventilation ability, high required combustion temperature, etc. A blast tube is disposed in a rotary kiln type combustion chamber, and a blast cap is disposed on the blast tube to distribute wind in reason. Accordingly, the device not only has small volume and high combustion temperature, but also can play the roles of wind supply, turning and agitation to residual inflammable matter in the fly ash. The inflammable matter in the fly ash is burnt fully and burnt out, and therefore, the harmful matter of the inflammable class in the fly ash is effectively reduced. The utility model further solves the problem of secondary pollution which is created possibly because the garbage is burnt.
Description
The utility model relates to a kind of swinging burner, the fly ash refiring device that contains harmful residual substance that produces after particularly a kind of waste incineration.
At present, be used for the burners such as grate furnace, fluid bed, rotary kiln stove of waste incineration,, contain the not organic substance of combustion toward contact in the flying dust after burning owing to reasons such as incineration temperature, residence time of material, such as, BaP, dioxin etc.BaP is a kind of strong carcinogenicity material, is mainly generated by anoxycausis.Dioxin contamination is the hot issue that causes international community's common concern in recent years, and it is a kind of toxicity extremely toxic substance higher 1000 times than potassium cyanide, is mainly generated by chlorine-bearing compound in combustion process.These extremely toxic substances can burn under the high temperature of oxygen abundance, so can utilize the method removal flammable nuisance wherein of fly ash refiring.But because the flying dust granularity is very little, the draught capacity in the ash is poor, and it almost is impossible adopting the general fluidized bed type or the grate firing type of furnace that flying dust is fired again; In contrast to this, it is little that rotary kiln type incinerator has a volume, drop into auxiliary fuel after, ignition temperature is higher, is fit to handle flying dust.But because common rotary kiln type incinerator is at smoke space cloth wind, this cloth wind is not suitable for that granularity is very little, the fly ash refiring of accumulation and draught capacity difference, and is particularly relatively poor to the flammable class harmful substance effect that reduces in the flying dust.
Deficiency and defective at the prior art existence, purpose of the present invention and task provide a kind of rotary kiln type fly ash refiring device, this installs, and not only volume is little, the ignition temperature height, and can play air feed, upset and stirring action to remaining combustible in the flying dust, make that combustible fully burns and after-flame in the flying dust, thereby effectively reduce the flammable class harmful substance in the flying dust.
The utility model is achieved by the following technical solution: a kind of rotary kiln type fly ash refiring device, it mainly is made up of parts such as revolution combustion chamber, combustor exit section, chamber front end lid, ash discharging hole, burner, flying dust inlet, exhanst gas outlet and transmission mechanisms, it is characterized in that in the grey emulsion zone of described revolution combustion chamber, arranging the ajutage that one or more is fixing, and on this pipe, arrange blast cap along centre of gyration line direction.
Because above-mentioned ajutage is arranged in the grey emulsion zone and along the centre of gyration line direction of revolution combustion chamber and arranges, and on airduct, be furnished with blast cap, allow airduct be immersed in the flying dust all the time, make the flying dust constantly upset under the combustion chamber of rotating drives that enters in the combustion chamber, and mix with air that ajutage is sent in the flying dust, thermal-flame and high-temperature flue gas that the burner spray is come directly heat flying dust.Airduct also plays remaining combustible upset, stirring action in the flying dust except that the air-supply effect, and combustible fully burns and the purpose of after-flame thereby reach.
Accompanying drawing 1 is an overall structure schematic diagram of the present utility model.
Among the figure: the 1-exhanst gas outlet; 2-combustor exit section; The 3-ash discharging hole; 4-turns round the combustion chamber; The 5-burner; 6-flying dust inlet; The 7-ajutage; 8-fly ash refiring air intake; The 9-transmission mechanism; The 10-base; Flying dust Free Surface in the 11-combustion chamber; The 12-blast cap; 13-ash emulsion zone; 14-ash dilute-phase zone.
Specifically describe concrete structure of the present utility model, operation principle and add embodiment most below in conjunction with accompanying drawing:
Send into revolution combustion chamber 4 from the pending flying dust that the incinerator deduster comes out through flying dust inlet 6, drive 4 rotations of revolution combustion chamber by transmission mechanism 9, start burner 5, flame and flue gas directly blow to flying dust surface to be fired, and this burner adopts fuel oil or combustion gas all can.In order to decompose the dioxin in the flying dust, need to be heated to the flying dust temperature more than 800 ℃ and to keep certain time of staying.Combustible in the flying dust needed air that burns enters ajutage 7 from fly ash refiring air intake 8, uniformly air is sent in the flying dust by blast cap 12.Ajutage 7 should be immersed in the grey emulsion zone 13, is lower than flying dust Free Surface 11.Like this, ajutage also plays upset, stirring action to remaining combustible in the flying dust except the air-supply effect, and combustible fully burns and the purpose of after-flame thereby reach.Revolution back, combustion chamber is a combustor exit section 2, in the further burning here of the incomplete material of revolution combustion chamber internal combustion, gas fume after burning is got rid of from exhanst gas outlet 1, the flue gas of discharging can enter incinerator and carry out dust removal process, flying dust after the burning is discharged from ash discharging hole 3, send landfill yard after qualified on inspection.
One end of above-mentioned ajutage can be fixed on the revolution chamber front end and cover, and its other end is fixed on the wall of combustor exit section 2.Like this, when rotated the revolution combustion chamber, ajutage was fixed, thereby this airduct is submerged in the flying dust of burning all the time.When in grey emulsion zone, arranging many ajutages, preferably evenly arrange.
The utility model compared with prior art has the following advantages and beneficial effect: this ash reburning appts is for flying Ash particle is little, and draught capacity is poor, requires the ignition temperature high, arranges ajutage in the ring kiln type combustion furnace, and Arrange blast cap at airduct, carry out reasonable wind distribution. Therefore, it is little that this device not only has a volume, the ignition temperature height, and And can play air feed, upset and stirring action to remaining combustible in the flying dust, combustible is fully burnt and After-flame, thus flammable class harmful substance in the flying dust effectively reduced, further solved because waste incineration might be made The secondary pollution problem that becomes.
