Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail, but the embodiment should not be construed as it is right
Limitation of the invention.
Referring to Fig. 1, two-stage high-efficient atomizing oil gun of the present invention, including pipette tips 14 and the body of a gun 15, the pipette tips 14 are provided with bubble
Room 2 and the spout 1 positioned at the head of bubble chamber 2, the body of a gun 15 be provided be coaxially disposed, mutually isolated inner tube 6 and outer tube 5, institute
State the head of the body of a gun 15 and be provided with the connector 18 being connected with inner tube 6 and outer tube 5 respectively, said inner tube 6 and outer tube 5 respectively with oil-feed
Mouth 13 is connected with atomization gas import 12, and oil and gas distributor 4 is provided between the afterbody of the bubble chamber 2 and the head of connector 18, described
Oil and gas distributor 4 is sequentially provided with coaxial connected jet 11, vortex chamber 8 and cumulative room 3 from tail to the end, the jet 11 with
Inner tube 6 and connector 18 form fuel flow path, and the rear side wall of the vortex chamber 8 is evenly distributed radial air inlet mouthful 10, the whirlpool
The middle part of rotation room 8 is evenly distributed injection well 9, and the rear side wall of the vortex chamber 8 is around air disengagement chamber 20, the edge of the connector 18
Circumferentially it is evenly equipped with the annular interior cavity of connection outer tube 5 and the axial intercommunicating pore 17 of air disengagement chamber 20, the connection cumulative of the injection well 9
The inner chamber of room 3 and air disengagement chamber 20, the radial air inlet mouthful 10 connect vortex chamber 8 and air disengagement chamber 20.
The axis of the injection well 9 is set at an angle with the axis of the body of a gun 15, in the present embodiment, the injection well 9
Axis and the axis angle of the body of a gun 15 be 15~30 °, in optimum embodiment, axis and the axis of the body of a gun 15 of the injection well 9
Angle is 20 °.
Being shaped as the spout 1 is inner small outer big.The head of the vortex chamber 8 is stretched into cumulative room 3.
The opening size of the injection well 9 is less than the inner chamber of cumulative room 3 and the opening size of air disengagement chamber 20；The axial direction
The opening size of intercommunicating pore 17 is less than the annular interior cavity of outer tube 5 and the opening size of air disengagement chamber 20；The radial air inlet mouthful
10 opening size is less than vortex chamber 8 and the opening size of air disengagement chamber 20；The opening size of the jet 11 is less than whirlpool
Rotation room 8 and the opening size of inner tube 6.
The afterbody of the body of a gun 15 is provided with tail chamber 16, and the tail chamber 16 is connected with inner tube 6 and oil inlet 13 respectively, the tail
Chamber 16 is isolated with outer tube 5 by tail circle 19.
The course of work of the invention：
Fuel oil sends 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 form vortex at a high speed, this is vortexed stirs the fuel oil that jet 11 is sprayed into be formed at a high speed
Vortex gas-oil the two phase flow for rotating at a high speed, in the interior fuel oil for rotating at a high speed of vortex chamber 8 after the head spout for going out vortex chamber 8,
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.The oil-gas two phase flow for completing the atomization of first time vortex centrifugal obtains the buffering of energy and gathers in cumulative room 3
Collection, and less than 100 μm tiny, the oil vacuole of uniform " oily bag gas " are formed, these oil vacuoles are subject to by injection well in cumulative room 3
The brute force attack of the second tunnel compressed air of 9 feedings and the lower completion energy supplement of agitation, and cumulative room 3 is gone out, reach space more
In big bubble chamber 2, and slow down herein, expand, flow and deform, finally the spout 1 from Oil gun head 7 sprays at a high speed, from
The oil vacuole that spout 1 sprays at a high speed, because the compressed air pressure in oil vacuole is more than extraneous air pressure, oil vacuole sprays spout 1
Explode immediately afterwards, form the oil particles of granularity Suo Taier coefficient Ss MD≤10 μm, complete secondary bubble blast atomization.
Innovative point of the invention：
1st, vortex chamber 8 and cumulative room 3 are provided with oil and gas distributor 4
2nd, in the presence of Venturi effect, vortex chamber 8 can produce negative-pressure sucking to act on, and fuel oil can be by certainly without pressure
It is dynamic to be drawn into oil gun.The compressed air entered from atomization gas import 12 is by oil gun outer tube 5 into being divided into before oil and gas distributor 4
Two-way：Because the opening size of radial air inlet mouthful 10 is less than vortex chamber 8 and the opening size of air disengagement chamber 20, from radial air inlet
There is Venturi effect all the way into vortex chamber 8 in mouth 10, and the compressed air that this direction enters is produced and be vortexed at a high speed drive combustion
Oily superhigh speed rotation, this is vortexed with negative-pressure sucking effect, and it can provide certain negative pressure so that fuel oil without pressure just
Vortex chamber 8 can be inhaled into；Because the opening size of injection well 9 is less than the inner chamber of cumulative room 3 and the open-mouth ruler of air disengagement chamber 20
Very little, 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
First time be broken atomization after fuel oil energy be consumed totally, if at this moment directly sprayed from spout 1, the jet power of fuel oil
Degree is very weak.And it is provided with cumulative room 3 so that brute force attack and agitation of the fuel oil that vortex chamber 8 sprays in the second tunnel compressed air
Lower completion energy supplement, improves the injection energy of the outlet of oil gun spout 1, it is ensured that the atomizing effect of fuel oil so that granularity
Suo Taier coefficients reach the level of SMD≤10 μm.
3rd, the present invention cannot be only used for the oil gun of fuel oil, on the accident spray equipment of the desulfurization island for applying also for power plant,
The places such as the spraying humidification of electric cleaner entrance are can also be used for, is applied also in the dedusting of improvement PM2.5.
Obviously, those skilled in the art can carry out various changes and modification without deviating from essence of the invention to the present invention
God and scope.So, if these modifications of the invention and modification belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising these changes and modification.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
