Description
Technical field
The present invention relates to a kind of atomizer for dry fog device for reducing dust.
Background technology
The U.S.《Coal Time-Life News》Entitled " Colorado School of Mines solves the control of inhalable dust " one delivered
Mentioned in text：The probability adsorbed, filter, condensed when water fog particle is close with dust granules size is maximum.Suppress 2.5 μm of levels
Dust granules, then necessarily require wet dust removal globule particle within this range.
Dry fog particle is at 2.8 μm~10 μm, due to identical with dust granules size, and dust raises up when running into water droplet, quilt
Adsorb and condense into cluster of grains, under gravity, cluster of grains declines, so as to be suppressed.
In the prior art, general is to use Patent No. CN200720101066.5, patent name to be atomized, and is made
For the shower nozzle of dry fog generating means, but in use, there is following problem in the shower nozzle：1st, the shower nozzle was being used
Blast pipe 2 and water inlet pipe 1 are all easily blocked in journey, due to dry fog shower nozzle be it is a large amount of use simultaneously and uninterruptedly for a long time, work as shower nozzle
Water inlet pipe 1 or blast pipe 2 when there is any one blocking, will be unable to produce dry fog, so that can not be to the airborne dust in scope
Play a part of depositing dust；2nd, first 7 when in use, by colliding the dry fog produced, to fly upward scope unsatisfactory for cylinder concussion, by
Larger in cylinder concussion head cross-sectional area, the dry fog collision rift sprayed with shower nozzle has larger a part of dry fog by reverse
Collision reaction force and flown upward to opposite direction, it is impossible to so that the dry fog of all ejections is ejected into the range of needing depositing dust,
So that existing atomizer spraying utilization rate is low.
The content of the invention
Present invention solves the technical problem that being to provide a kind of atomizer for dry fog device for reducing dust, to solve existing skill
The technical problem that atomizer is easily blocked in art, utilization rate of spraying is low.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of atomization for dry fog device for reducing dust is sprayed
Head, including the first shower nozzle and the second shower nozzle, along the first shower nozzle axis provided with fluid passage, first shower nozzle is into cone
Shape, thinner one end of the first shower nozzle is that fluid goes out to flow end, and the first shower nozzle goes out to flow provided with taper concussion head of the surface for cambered surface in front of end,
Concussion head is fixedly connected by many steel wires with the first shower nozzle, and a plurality of helicla flute, each bar spiral shell are offered in the cambered surface of earthquake head
Spin slot is uniformly distributed around concussion head axis, and the cone top part of the helicla flute from the concussion head gradually broadens to cone bottom；
Second shower nozzle is threaded in the first shower nozzle, along the second shower nozzle axis provided with one article be connected with fluid passage the
Two runners, there is multiple inlet openings connected with second flow channel, tool of the second flow channel away from the first shower nozzle on the second shower nozzle outer wall
There is one section of tubaeform air inlet.
Fluid passage is truncated cone-shaped, and the thicker one end in fluid passage is connected with second flow channel.
The angle intake between axially bored line and second flow channel axis is 15 degree to 30 degree.
Compared with prior art, the shower nozzle in this patent is shaken head and realized and shaken to colliding in cambered surface taper by cambered surface taper
The fluid for swinging head carries out spiral dispersing, using the flexible characteristic of steel wire, in spray process, and spraying is produced with concussion head collision
Raw impact can pass through steel wire cushioning balance so that concussion head is under dynamic equilibrium state, not only makes dry fog spray regime more
Greatly, and situation that to be not in dry fog spray round about after collision, spraying utilization rate is improved, due to spiral
The spiral drainage of groove so that the movement locus curl after dry fog ejection, increases the movement locus after dry fog sprays,
So that the dust-laying effect of single spray reach it is best；On the other hand, truncated cone-shaped structure in fluid passage is improved with shaking before head collision
The movement velocity of fluid, makes momentum before spray impingement maximum, and then make it that the jet length of collision rift spraying is farther；The opposing party
Face, the definition of the angle between water inlet axially bored line and second flow channel axis enables current to be tangential to blow and hit fluid so that spray
Mist scope is wider.
Brief description of the drawings
The present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is cross-sectional view of the invention,
Main structure diagrams of the Fig. 2 for the present invention on concussion head,
Overlooking the structure diagrams of the Fig. 3 for the present invention on concussion head.
In figure：First shower nozzle 10, fluid passage 11, steel wire 12, the second shower nozzle 20, second flow channel 21, inlet opening 23, air inlet
Mouth 22, concussion first 30, helicla flute 31, rubber washer 40.
Embodiment
As shown in Fig. 1 to 3, a kind of atomizer for dry fog device for reducing dust,
Including the first shower nozzle 10 and the second shower nozzle 20, along the axis of the first shower nozzle 10 provided with a fluid passage 11, described first
Shower nozzle 10 is tapered, and the thinner one end of the first shower nozzle 10 is that fluid goes out to flow end, and it is arc that the first shower nozzle 10, which goes out to flow in front of end to be provided with surface,
The taper concussion first 30 in face, concussion first 30 is fixedly connected by many steel wires 12 with the first shower nozzle 10, the cambered surface of earthquake first 30
On offer a plurality of helicla flute 31, each bar helicla flute 31 is uniformly distributed around shaking first 30 axis, and the helicla flute 31 is from institute
The cone top part for stating concussion first 30 gradually broadens to cone bottom；
Second shower nozzle 20 is threaded in the first shower nozzle 10, along the axis of the second shower nozzle 20 provided with one and the phase of fluid passage 11
The second flow channel 21 of connection, there is multiple inlet openings 23 connected with second flow channel 21, second flow channel on the outer wall of the second shower nozzle 20
21 have one section of tubaeform air inlet 22 away from the first shower nozzle 10.
Shower nozzle in this patent shakes first 30 by cambered surface taper to be realized to colliding the fluid in cambered surface taper concussion first 30
Spiral dispersing is carried out, using the flexible characteristic of steel wire 12, in spray process, is sprayed with shaking rushing for first 30 collision generation
Hitting can be by the cushioning balance of steel wire 12 so that concussion first 30 is under dynamic equilibrium state, not only makes dry fog spray regime bigger,
And be not in the situation that dry fog sprays round about after collision, spraying utilization rate improved, due to helicla flute
31 spiral drainage so that the movement locus curl after dry fog ejection, increases the movement locus after dry fog sprays,
So that the dust-laying effect of single spray reach it is best.
Fluid passage 11 is truncated cone-shaped, and the thicker one end in fluid passage 11 is connected with second flow channel 21.The round platform of fluid passage 11
Shape structure improves the movement velocity with shaking fluid before first 30 collision, makes momentum before spray impingement maximum, and then cause collision rift
The jet length of spraying is farther.
Angle between the axis of inlet opening 23 and the axis of second flow channel 21 is 15 degree to 30 degree.The axis of inlet opening 23 and second
The definition of angle between the axis of runner 21 enables current to be tangential to blow and hit fluid so that spread of spray is wider.
