Description

Foam-making apparatus
Technical field
The present invention relates to a kind of foam-making apparatus, especially a kind of foam-making apparatus with annular jet and spiral flow-disturbing part.
Background technology
It is all rely on suction type fixed froth installation or compressed air foam fire-extinguishing apparatus that current tank fire, airport leak oil plant fire etc., and the injection of these extinguishing devices is all spray based on gas-liquid two-phase.Wherein, foam maker is the device that gas-liquid enters that mixing produces foam, and gas-liquid blending quality directly determines the quality that foam generates.Therefore the foam maker that research structure is simple, quality is firm is extremely important.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention proposes a kind of novel foam generating means with annular jet and spiral flow-disturbing part, the present invention adopts following technical scheme:
Foam-making apparatus, comprises blending room and annular jet entrance, and described annular jet entrance comprises liquid phase entrance and gas phase entrance, and gas phase entrance is divided into center-aisle and wall passage, and the circular passage of center-aisle and wall passage centre is liquid phase entrance; Blending indoor are provided with spirality flow-disturbing part, are provided with filter screen before the outlet of blending room;
Gas phase entrance connects source of the gas, liquid phase entrance connects foam solution feedway, when liquid phase enters blending room ringwise, center and the periphery of annular are gas phase, first gas-liquid two-phase runs into spirality flow-disturbing part, larger continuous print liquid block is broken into less liquid block or brin, then through filter screen, less liquid block and brin is dispersed into tiny drop or bubble, tiny drop or bubble connect apparatus for spray of foam by the outlet of blending room.
Further, described gas phase entrance is provided with gas phase two-way flow control valve, and gas phase two-way flow control valve extends to center-aisle by wall passage, regulates gas phase to enter the flow proportional of blending indoor along center-aisle and wall passage.
Further, the radius of spin streamwise of described spirality flow-disturbing part reduces gradually, and spirality flow-disturbing part has crushing function to annular liquid phase.
Further, described spirality flow-disturbing part is welded in blending chamber interior walls.
The Advantageous Effects adopting as above technical scheme to obtain is:
With the foam-making apparatus gas-liquid two-phase annular entry of annular jet and spiral flow-disturbing part, wherein in the middle of gas phase subentry and adherent two passages, liquid phase enters between the two-way of gas phase, and the entrance of liquid phase is annular.After gas phase two-phase enters blending room, run into the spirality flow-disturbing part of blending indoor, enhance gas-liquid blending effect.Spirality flow-disturbing part streamwise screw diameter reduces gradually, has crushing effect to the annular liquid phase that entrance enters.The downstream of spirality flow-disturbing part, arranges one deck filter screen, further enhances gas-liquid blending effect.
Accompanying drawing explanation
Fig. 1 is foam-making apparatus structural representation.
Fig. 2 is spirality flow-disturbing part schematic diagram.
In figure, 1 liquid phase entrance, 2 gas phase entrances, 3 gas phase two-way flow control valves, 4 gas jet mouths, 5 liquid phase jet orifices, 6 blending rooms, 7 spirality flow-disturbing parts, 8 blending room outlets, 9 filter screens.
Detailed description of the invention
1 to 2 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
The gas-liquid blending foam maker of New Ring-like Type jet band spiral flow spoiler of the present invention, mainly innovate around the entry form of gas-liquid two-phase and the flow-disturbing part form of blending indoor, gas-liquid two-phase entry form determines the initial flow-field structure of blending indoor, and flow-disturbing part determines the gas-liquid mixed effect of blending indoor.
Foam-making apparatus, comprises blending room 6 and annular jet entrance, and described annular jet entrance comprises liquid phase entrance 1 and gas phase entrance 2, and gas phase entrance 2 is divided into center-aisle and wall passage, and the circular passage of center-aisle and wall passage centre is liquid phase entrance; Blending indoor are provided with spirality flow-disturbing part 7, are provided with filter screen 9 before the outlet of blending room.
Gas phase entrance connects source of the gas, gas phase entrance and junction, blending room are gas jet mouth 4, liquid phase entrance connects foam solution feedway, liquid phase entrance and junction, blending room are liquid phase jet orifice 5, when liquid phase enters blending room ringwise, center and the periphery of annular are gas phase, first gas-liquid two-phase runs into spirality flow-disturbing part, larger continuous print liquid block is broken into less liquid block or brin, through filter screen, less liquid block and brin are dispersed into tiny drop or bubble again, tiny drop or bubble connect apparatus for spray of foam by the outlet of blending room.
Gas phase entrance is provided with gas phase two-way flow control valve 3, gas phase two-way flow control valve 3 extends to center-aisle by wall passage, gas phase is regulated to enter the flow proportional of blending indoor along center-aisle and wall passage, to reach good gas-liquid blending effect and foam generation quality.
The radius of spin streamwise of spirality flow-disturbing part reduces gradually, and spirality flow-disturbing part has crushing function to annular liquid phase.Spirality flow-disturbing part is welded in blending chamber interior walls.
Certainly; more than illustrate and be only preferred embodiment of the present invention; the present invention is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this description; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this description, protection of the present invention ought to be subject to.
