Abstract

The invention discloses a kind of foam-making apparatus of band combination spoiler, including blending room, the combination spoiler is indoor positioned at blending, combination spoiler includes being additionally provided with filter screen installed in the cross spoiler and the spiral shape spoiler after cross spoiler, the exit for blending room that blend at chamber inlet.Gas phase entrance connects source of the gas, liquid phase entrance connects foam liquid supplying device, after gas-liquid two-phase enters blending room, initially encounter the broken of cross spoiler, continuous main liquid stream is dispersed into thinner liquid stream, then runs into spiral shape spoiler, so as to which thinner liquid stream to be dispersed into tiny liquid block or brin again, tiny liquid block and brin are dispersed into tiny drop or bubble through filter screen again, the outlet of tiny drop or bubble by blending room connects apparatus for spray of foam.In the case of reduction Liquid Flow resistance as few as possible, gas-liquid blending effect is largely improved, strengthens foam luminous efficiency.

Description

A kind of foam-making apparatus of band combination spoiler
Technical field
The present invention relates to a kind of foam-making apparatus, especially a kind of foam-making apparatus of band combination spoiler.
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 are 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 foam-making apparatus of band combination spoiler, adopted With following technical scheme:
A kind of foam-making apparatus of band combination spoiler includes blending room, and blending the entrance of room includes gas phase entrance and liquid Phase entrance, liquid phase entrance is in centre, and gas phase entrance is around liquid phase entrance, it is characterised in that the combination spoiler is located at Blending is indoor, combination spoiler include being arranged on cross spoiler at blending chamber inlet and installed in cross spoiler it Spiral shape spoiler afterwards, the exit for blending room are additionally provided with filter screen;
Gas phase entrance connects source of the gas, and liquid phase entrance connection foam liquid supplying device, gas-liquid two-phase is into after blending room, first The broken of cross spoiler is run into, continuous main liquid stream is dispersed into thinner liquid stream, then runs into spiral shape spoiler, from And thinner liquid stream is dispersed into tiny liquid block or brin again, then through filter screen be dispersed into tiny liquid block and brin tiny Drop or bubble, the outlet of tiny drop or bubble by blending room connects apparatus for spray of foam.
Preferably, the inlet diameter size of the blending room is small compared with the diameter of blending room, and gas-liquid two-phase enters from entrance to be mixed Expansion flowing occurs behind mixed interior.
Preferably, the cross spoiler is welded in blending chamber interior walls, and it is indoor that spiral shape spoiler is welded on blending On wall.
Preferably, the radius of spin streamwise of the spiral shape spoiler is gradually reduced, and spiral shape spoiler is to entering Entering the indoor annular liquid phase of blending has crushing function.
Use the advantageous effects that as above technical scheme obtains for:
Blend room and cross and spiral shape combination spoiler is simple in construction, handling ease, installation cost is relatively low.To the greatest extent may be used In the case of reduction Liquid Flow resistance that can be few, gas-liquid blending effect is largely improved, strengthens foam luminous efficiency.
Brief description of the drawings
Fig. 1 is the foam-making apparatus structural representation that a kind of band combines spoiler.
Fig. 2 is cross spoiler schematic diagram.
Fig. 3 is spiral shape spoiler schematic diagram.
Embodiment
It is described further with reference to 1 to 3 pair of embodiment of the invention of accompanying drawing:
A kind of foam-making apparatus of band combination spoiler, including blending room 3, the entrance of blending room 3 include gas phase entrance 2 With liquid phase entrance 1, liquid phase entrance 1 is in centre, and gas phase entrance 2 is around liquid phase entrance 1, and the combination spoiler is positioned at blending Interior, combination spoiler are included installed in the cross spoiler 4 blended at chamber inlet and after cross spoiler Spiral shape spoiler 5, the exit for blending room is additionally provided with filter screen 6.
Gas phase entrance connects source of the gas, and liquid phase entrance connection foam liquid supplying device, gas-liquid two-phase is into after blending room, first The broken of cross spoiler is run into, continuous main liquid stream is dispersed into thinner liquid stream, then runs into spiral shape spoiler, from And thinner liquid stream is dispersed into tiny liquid block or brin again, then through filter screen be dispersed into tiny liquid block and brin tiny Drop or bubble, the outlet 7 of tiny drop or bubble by blending room connects apparatus for spray of foam.
It is small compared with the diameter of blending room to blend the inlet diameter size of room, gas-liquid two-phase occurs after entering blending interior from entrance Expansion flowing.
Cross spoiler is welded in blending chamber interior walls, and spiral shape spoiler is welded in blending chamber interior walls.
The radius of spin streamwise of spiral shape spoiler is gradually reduced, and spiral shape spoiler blends indoor to entering Annular liquid phase has crushing function.
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.
