Description
Technical field
It is especially a kind of to occur with annular jet and the foam of spiral spoiler the present invention relates to a kind of foam-making apparatus
Device.
Background technology
Current tank fire, airport leakage oil plant fire etc. are steeped by suction type fixed froth installation or compressed air
Foam extinguishing device, the injection of these extinguishing devices is all based on gas-liquid two-phase injection.Wherein, foam maker is that gas-liquid entrance is mixed
The device for producing foam is closed, gas-liquid blending quality directly determines the quality of foam generation.Therefore research structure is simple, quality is firm
Foam maker it is extremely important.
The content of the invention
In order to solve the deficiencies in the prior art, the present invention proposes a kind of new bubble with annular jet and spiral spoiler
Foam generating means, the present invention is adopted the following technical scheme that：
Foam-making apparatus, including blending room and annular jet entrance, the annular jet entrance include liquid phase entrance and
Gas phase entrance, the circular passage that gas phase entrance is divided into the middle of center-aisle and wall passage, center-aisle and wall passage is liquid
Phase entrance；Blending is indoor to be provided with spiral shape spoiler, blends and filter screen is provided with before the outlet of room；
Gas phase entrance connects source of the gas, and liquid phase entrance connection foam liquid supplying device, liquid phase enters when blending room in a ring, ring
The center and periphery of shape are gas phase, and gas-liquid two-phase initially encounters spiral shape spoiler, by larger continuous liquid block be broken into compared with
Small liquid block or brin, then less liquid block and brin be dispersed into through filter screen tiny drop or bubble, tiny drop or
Outlet of the bubble by blending room connects apparatus for spray of foam.
Further, the gas phase entrance is provided with gas phase two-way flow control valve, and gas phase two-way flow control valve is by wall
Face passage extends to center-aisle, and regulation gas phase enters along center-aisle and wall passage blends indoor flow proportional.
Further, the radius of spin streamwise of the spiral shape spoiler is gradually reduced, spiral shape spoiler pair
Annular liquid phase has crushing function.
Further, the spiral shape spoiler is welded in blending chamber interior walls.
Use the advantageous effects that as above technical scheme is obtained for：
Foam-making apparatus gas-liquid two-phase annular entry with annular jet and spiral spoiler, wherein in gas phase subentry
Between and adherent two passages in face, liquid phase enters between the two-way of gas phase, and the entrance of liquid phase is annular.Gas-liquid two-phase, which enters, to be mixed
Behind mixed room, the indoor spiral shape spoiler of blending is run into, gas-liquid blending effect is enhanced.Spiral shape spoiler streamwise spiral shell
Reduced diameter is revolved, there is crushing effect to the annular liquid phase that entrance enters.The downstream of spiral shape spoiler, arranges a metafiltration
Net, further enhances gas-liquid blending effect.
Brief description of the drawings
Fig. 1 is foam-making apparatus structural representation.
Fig. 2 is spiral shape spoiler schematic diagram.
In figure, 1 liquid phase entrance, 2 gas phase entrances, 3 gas phase two-way flow control valves, 4 gas jets mouthful, 5 liquid phase jets
Mouthful, 6 blending rooms, 7 spiral shape spoilers, 8 blending room outlets, 9 filter screens.
Embodiment
It is described further with reference to 1 to 2 pair of embodiment of the invention of accompanying drawing：
Gas-liquid blending foam maker of the New Ring-like Type jet of the present invention with spiral flow spoiler, mainly around gas-liquid two-phase
Entry form and the indoor spoiler form of blending are innovated, and gas-liquid two-phase entry form determines the initial of blending interior
Flow field structure, and spoiler determines the indoor gas-liquid mixed effect of blending.
Foam-making apparatus, including blending room 6 and annular jet entrance, the annular jet entrance include liquid phase entrance 1
With gas phase entrance 2,2 points of gas phase entrance is the circular passage in the middle of center-aisle and wall passage, center-aisle and wall passage
For liquid phase entrance；Blending is indoor to be provided with spiral shape spoiler 7, blends and filter screen 9 is provided with before the outlet of room.
Gas phase entrance connects source of the gas, and gas phase entrance is gas jet mouthful 4, liquid phase entrance connection foam with blending room junction
Liquid supplying device, liquid phase entrance is liquid phase jet orifice 5 with blending room junction, and liquid phase enters when blending room in a ring, annular
Center and periphery are gas phase, and gas-liquid two-phase initially encounters spiral shape spoiler, larger continuous liquid block are broken into less
Liquid block or brin, then less liquid block and brin are dispersed into through filter screen tiny drop or bubble, tiny drop or bubble
Apparatus for spray of foam is connected by the outlet for blending room.
Gas phase entrance is provided with gas phase two-way flow control valve 3, and gas phase two-way flow control valve 3 is extended to by wall passage
Center-aisle, regulation gas phase enters along center-aisle and wall passage blends indoor flow proportional, to reach preferable gas-liquid
Mixing effect and foam generation quality.
The radius of spin streamwise of spiral shape spoiler is gradually reduced, and spiral shape spoiler has broken to annular liquid phase
Broken function.Spiral shape spoiler is welded in blending chamber interior walls.
Certainly, described above is only presently preferred embodiments of the present invention, and the present invention is not limited to enumerate above-described embodiment, should
When explanation, any those skilled in the art are all equivalent substitutes for being made, bright under the guidance of this specification
Aobvious variant, all falls within the essential scope of this specification, ought to be protected by the present invention.
