Racemization blade E is provided with coal dust spout C, racemization blade E is sleeved on swing pipe D one end, and the swing pipe D other end is provided with swing pipe
Adjust wheel disc F, it is characterised in that：Swing pipe D is in hollow tubular structure, and swing pipe D, which is set inner chamber, is provided with igniting spray gun B；Point fire-fighting
Rifle B includes pipette tips 14 and the body of a gun 15, and pipette tips 14 are provided with bubble chamber 2 and the spout 1 positioned at the end of bubble chamber 2, and the tail end of pipette tips 14 leads to
Cross oil and gas distributor 4 to be connected with the body of a gun 15, be coaxially arranged with mutually isolated inner tube 6 and outer tube 5 in the body of a gun 15, inner tube 6 and outer
Pipe 5 is connected with oil inlet 13 and atomization gas import 12 respectively.
The head of the body of a gun 15 is provided with the connector 18 being connected respectively with inner tube 6 and outer tube 5, the oil gas point of the afterbody of bubble chamber 2
Orchestration 4 is connected with the connector 18 on the head of the body of a gun 15, and oil and gas distributor 4 is sequentially provided with coaxially connected jet from tail to the end
11st, vortex chamber 8 and cumulative room 3, jet 11 form fuel flow path, the afterbody side wall of vortex chamber 8 edge week with inner tube 6 and connector 18
To uniform radial air inlet mouth 10, the middle part of vortex chamber 8 is evenly distributed injection well 9, and the afterbody side wall of vortex chamber 8 is around air disengagement chamber
20, connector 18 is evenly distributed the annular interior cavity of connection outer tube 5 and the axial intercommunicating pore 17 of air disengagement chamber 20, injection well
The inner chamber of 9 connection cumulative room 3 and air disengagement chamber 20, radial air inlet mouth 10 connect vortex chamber 8 and air disengagement chamber 20.
Preferably, the axis of injection well 9 and the axis angle of the body of a gun 15 are 25 °.Spout 1 and the axis angle of the body of a gun 15
For 60 °；That is the atomizing angle of bubble atomized oil gun is expanded to 120 °, the oil-gas ratio of oil gun is redesigned, oil-gas ratio reaches
2:1, advanced technology so that oil gun just can be in 30 meter per second wind speed down-firings freely, and below this wind speed without stabilizer
It can stablize, complete burning.The afterbody of the body of a gun 15 is provided with tail chamber 16, and tail chamber 16 is connected with inner tube 6 and oil inlet 13 respectively, tail
Chamber 16 is isolated with outer tube 5 by tail circle 19.Igniting spray gun B afterbodys be provided with propulsion plant, can drive ignition spray gun B in swing pipe
Stretch out or retract in D.
Fuel oil is sent into inner tube 6 by oil inlet 13, and the jet 11 on oil and gas distributor 4 is reached by inner tube 6, then by spraying
Hydraulic fluid port 11 sprays into vortex chamber 8；Compressed air enters in oil gun outer tube 5 from atomization gas import 12, and in outer tube 5 and oil gun inner tube 6
Between annular interior cavity flowing, finally reach oil and gas distributor 4 before be divided into two-way：First via compressed air is from the footpath of vortex chamber 8
Enter vortex chamber 8 to air inlet 10, and formed and be vortexed at a high speed, this is vortexed stirs the fuel oil that jet 11 sprays into be formed at a high speed
Vortex gas-oily two phase flow of rotation at a high speed, in the interior fuel oil rotated at a high speed of vortex chamber 8 after the head spout of vortex chamber 8 is gone out,
It is shredded under the centrifugal action of high speed rotation, completes first break and be atomized into granularity Suo Taier coefficient Ss MD≤100
μm oil particles.In the presence of Venturi effect, vortex chamber 8 can produce negative-pressure sucking effect, and fuel oil can be by without pressure
It is automatically drawn into oil gun.Divide before entering oil and gas distributor 4 by oil gun outer tube 5 from the compressed air that atomization gas import 12 enters
For two-way：Because the opening size of radial air inlet mouth 10 is less than the opening size of vortex chamber 8 and air disengagement chamber 20, from radially entering
There is Venturi effect all the way into vortex chamber 8 in gas port 10, and the compressed air that this direction enters produces the drive that is vortexed at a high speed
The superhigh speed of fuel oil one rotates, and this, which is vortexed, has negative-pressure sucking effect, and it can provide certain negative pressure so that fuel oil is without pressure
Vortex chamber 8 can be inhaled into；Because the opening size of injection well 9 is less than the opening of the inner chamber of cumulative room 3 and air disengagement chamber 20
Size, according to Venturi effect, the second tunnel compressed air rapidly enters cumulative room 3 via injection well 9.Due to being sprayed from vortex chamber 8
The first time gone out be broken atomization after fuel oil energy be consumed totally, at this moment if directly sprayed from spout 1, the injection of fuel oil
Dynamics is very weak.And be provided with cumulative room 3 so that vortex chamber 8 spray fuel oil the second tunnel compressed air brute force attack and stir
Dynamic lower completion energy supplement, improves the injection energy of the outlet of oil gun spout 1, ensure that the atomizing effect of fuel oil so that particle
Du Suotaier coefficients reach the level of SMD≤10 μm.The oil-gas two phase flow of first time vortex centrifugal atomization is completed in cumulative room
Buffering and the aggregation of energy are obtained in 3, and forms the oil vacuole of less than 100 μm tiny uniform " oily bag gas ", these oil vacuoles exist
By the brute force attack for the second tunnel compressed air being sent into by injection well 9 and the lower completion energy supplement of agitation in cumulative room 3, and rush
Go out cumulative room 3, reach in the bigger bubble chamber 2 in space, and slow down herein, expand, flow and deform, finally from Oil gun head 7
On spout 1 spray at a high speed, the oil vacuole sprayed at a high speed from spout 1, because the compressed air pressure in oil vacuole is more than extraneous sky
Atmospheric pressure, oil vacuole explode immediately after spraying spout 1, form the oil particles of granularity Suo Taier coefficient Ss MD≤10 μm, complete secondary
Bubble blast atomization.
There is racemization blade E at the bispin pulverized-coal cyclone low separator A of W type boilers coal dust spout C center, and its effect is exactly to disappear
Except swirling eddy caused by pulverized-coal cyclone low separator A, coal dust spout C blow-through rigidity is kept, this racemization blade E is by hanging
Pipe D is suspended on the elbow of coal dust classifier A tops, and swing pipe regulation wheel disc F regulation racemization blades E insertion can be used deep
Degree, reach required racemization effect.It by this racemization blade E suspender replacement is hollow hanging pipe D that the utility model, which is, suspension rod
Regulation wheel disc is replaced by swing pipe regulation wheel disc F, and crude oil rifle is moved in this hollow hanging pipe D, realizes high wind resistance oil gun
In coal dust spout C central burner, all standing of the pyrotechnics flame to breeze airflow is realized.Oil gun is under the high speed impact of breeze airflow
It can still light a fire easily, catch fire and normally gone out without being blown out；This few-oil ignition oil gun and device are not provided with the steady of oil gun
Burner G, it does not change the blow-through performance of nozzles completely, maintains the rigidity of flame, oil gun energy in the environment of no flame holder
Enough stable burnings, its technology it is advanced leading.
Finally it is pointed out that above example is only the more representational example of the utility model.Obviously, this practicality is new
Type is not limited to above-described embodiment, can also there is many deformations.Every foundation the technical essence of the utility model is to above example
Any simple modifications, equivalents, and modifications done, it is considered as belonging to the scope of protection of the utility model.
