Description
Technical field
The invention belongs to gas combustion apparatus technical fields, and in particular to industrial combustion gas rotary energy saving low NO.
Background technique
Currently, to achieve the effect that energy efficiency, drop nitrogen, being all using moment in terms of energy efficiency in industrial production
The two ways that air-fuel is mixed and premixed in advance, and both modes will cause air excess and lack of air, cause flue gas
It takes away a large amount of thermal energy and combustion gas is thermally decomposed and caused the waste of combustion gas.
The flue gas heat of furnace body will be discharged in the waste-heat recovery device used in recent years, by heat exchanger, by combustion air
Preheated, this mode really can energy-conservation of consumption reduction, the disadvantage is that figure is big, pipeline is long, increases input cost, secondly, using
In can consume a large amount of blower electric energy, greatly increase use cost.
In terms of dropping nitrogen, at present frequently with combustion gas fractional combustion and air segmenting dispatching burning, although this mode has
Certain drop nitrogen effect, but discharged nitrous oxides standard is often still not achieved.
In recent years, more and more enterprises use external off-gas recovery pipeline, using exhaust fan, by part of smoke in furnace
Extraction is blended into combustion air, to reduce the oxygen content in air, to achieve the purpose that drop nitrogen.This mode is in practical application
In, due to the reduction of oxygen content in combustion air, causes flame rough burning occur, explosion occur, increase security risk.
Meanwhile a large amount of vapor generate condensed water to the cold in the flue gas of pumpback, the time, which has been grown, to generate serious corrosion to pipeline.Determine
Phase replaces recovered flue gas pipeline, equally will increase investment and use cost.Although this drop nitrogen mode has shortcomings, but because not having
There is new technology replacement, in face of drop nitrogen demand, enterprise must not still use it then.
Summary of the invention
Goal of the invention: the object of the present invention is to provide industrial combustion gas rotary energy saving low NOs, can reduce combustion head
And combustion flame temperature, while heated the combustion air of air chamber again, it avoids air and the multistage subsection of combustion gas from burning and causes
Waste of fuel and nitrogen oxides it is high.
Technical solution: in order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme:
Air heat is circumferentially arranged above air chamber and returns for industrial combustion gas rotary energy saving low NO, including air chamber
Storehouse is flowed, the bottom in air heat reflux storehouse is connected with air chamber；It is responsible in the setting combustion gas of the middle part of the air chamber, in combustion gas
Combustion gas spout is set in the middle part of the pipe shaft of supervisor, rotary combustion head main body is equipped on the top of burning supervisor, in the rotary combustion head
The bottom of main body is equipped with driving blade, and the rotary combustion head main body is fixed on combustion gas supervisor by bearing rotation.
Air inlet is set in the air chamber side, gas inlet pipe is set on the combustion gas supervisor.
The driving blade is in the bottom of rotary combustion head main body in circumferentially distributed.
The air heat reflux storehouse top extends at flame combustion, and middle part covers rotary combustion head main body, and lower part is prolonged
Extend to combustion gas spout.
Interstice coverage is formed between the rotary combustion head main body and air heat reflux storehouse.
The width of the interstice coverage is 3-5mm.
The gas of rotary combustion head body top is connect on the interstice coverage, under connect gas in pre-mixing cabin.
Region between pipeline section where the combustion gas spout and air heat reflux storehouse forms pre-mixing cabin.
Several unit spit tubes are distributed in rotary combustion head main body, the bottom of unit spit tube is connected with pre-mixing cabin.
Inventive principle: the formation of nitrogen oxides, by taking natural gas as an example, natural gas does not have self-contained, and formation mechenism is heat
Power type and Quick-type.Heating power type is that ignition temperature is locally excessively high, and nitrogen and oxygen in air is made to form combination.This requires controls
Combustion high temperature area, while reducing excess air coefficient；And Quick-type be because excessive combustion gas decompose after with the nitrogen knot in air
It closes, this requires increase excess air coefficient.Heating power type and Quick-type are a pair of contradictory bodies from dropping in nitrogen principle, crucial
It is to find reasonable excess air coefficient, in practice, due to the uncertainty of external condition, is difficult to get hold of, and rotatably fires
The high-temperature region of burning can be broken by burning head, meanwhile, burning again for flue gas reduces excess air coefficient, and energy conservation and drop nitrogen is allowed to accomplish
It is perfect unified.
Rotary combustion head main body forms centrifugation in burning and from flame, causes to burn unstable, and rotary combustion head master
The interstice coverage that body is formed with air heat reflux storehouse plays a key effect to rotary combustion head main body is stablized.The heat of secondary air simultaneously
Flowing had not only reduced the temperature of rotary combustion head main body, but also heated combustion air.
When air enters air chamber with certain pressure, after the combustion gas mixing of certain pressure, the kinetic energy of mixed gas is logical
Blade overdrive with dynamic bearing, rotary combustion head main body is made to generate rotation, meanwhile, most of mixed gas, which enters to be placed in rotate, fires
Burn the unit spit tube of head body interior；Another part mixed gas enters the seam of rotary combustion head main body and air heat reflux storehouse
Gap area forms complete flame combustion annulus (claiming steady fireworks flame).In combustion, rotary combustion head main body constantly rotates,
And steady fireworks flame plays the role of stable flame combustion state.The cold and hot convective exchange of air progress in air heat reflux storehouse, one
Aspect can reduce combustion head and combustion flame temperature, while heated the combustion air of air chamber again.
The utility model has the advantages that compared with prior art, industrial combustion gas rotary energy saving low NO of the invention passes through main sky
Air-flow and the kinetic energy of combustion gas drive the driving blade connecting with rotary combustion head main body, and rotary combustion head main body is driven to be revolved
Turn；The static combustion for changing conventional burners is rotary Dynamic Burning, and rotary combustion head main body and still air heat flow back
It is in that static circular ring shape flame wraps up rotary combustion head main body that storehouse, which is formed by interstice coverage,；Meanwhile avoiding the multistage of air and combustion gas
Waste of fuel and nitrogen oxides caused by sectional combustion remain high.
