Abstract
The invention discloses a foam generation device. The foam generation device comprises a mixing chamber. A quasi-Venturi tube section is arranged on the front portion of the mixing chamber. A spindle body turbulator is arranged on the rear portion of the mixing chamber. A gas source and a foam liquid supplying device are connected to an inlet of the mixing chamber. A filter screen is arranged in the downstream position of the spindle body. A foam ejecting device is connected to an outlet of the mixing chamber. The gas phase and the liquid phase are subjected to gas-liquid mixing under the restraint effect of the quasi-Venturi tube section firstly, and then the gas phase and the liquid phase are further subjected to gas-liquid mixing under the turbulence of the spindle body turbulator when encountering the spindle body turbulator in the downstream position; the inertia of the gas phase is small so that the gas phase turns rapidly to flow away from the periphery of the spindle body turbulator; the inertia of the liquid phase is large so that the liquid phase can collide with the windward surface of the spindle body turbulator to be dispersed into fine liquid drops or liquid filaments; the contact area of the gas phase and the liquid phase is increased in the collision area, the gas phase and the liquid phase pass through the filter screen in the downstream position of the spindle body turbulator, so that the liquid drops and the liquid filaments are further refined, and mixed foam liquid flows towards the downstream foam ejecting device through the outlet of the mixing chamber.
Description
Technical field
The present invention relates to a kind of foam-making apparatus, especially a kind of foam-making apparatus with class venturi pipeline section and spindle flow spoiler.
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 foam-making apparatus with class venturi pipeline section and spindle flow spoiler, the present invention adopts following technical scheme:
A kind of foam-making apparatus, comprise blending room, the front portion of blending room is class venturi pipeline section, the rear portion of blending room is provided with spindle flow spoiler, the entrance of blending room is connected with source of the gas and foam solution feedway, and the downstream of spindle is provided with filter screen, and the outlet of blending room connects apparatus for spray of foam;
After the entrance of gas-liquid two-phase blending room enters blending room, first gas-liquid blending under class venturi pipeline section restrictive function is subject to, then, gas-liquid two-phase runs into the flow-disturbing effect of spindle flow spoiler in downstream, further gas-liquid blending, gas phase inertia is less, rapid break-in flows away from the surrounding of spindle flow spoiler, liquid phase inertia is larger, collide with the windward side of spindle flow spoiler, liquid phase is dispersed into tiny drop or brin, increase in collision area gas-liquid two-phase contact area, at the downstream gas-liquid two-phase of spindle flow-disturbing part through filter screen, further refinement drop and brin, foam solution after blending is through the apparatus for spray of foam of blending room outlet flow to downstream.
Preferably, the entrance of described blending room comprises gas phase entrance and liquid phase entrance, and liquid phase entrance is in centre, and gas phase entrance is around liquid phase entrance.
Preferably, the inlet diameter size of described blending room is little compared with the diameter of blending room, and gas-liquid two-phase, after entrance enters blending indoor, expansion flowing occurs.
Preferably, described spindle flow spoiler is welded in blending chamber interior walls by cross frame.
Preferably, described class venturi pipeline section comprises contraction section and expansion segment, and namely the flow area of class venturi pipeline section first shrinks rear expansion, and gas-liquid two-phase first accelerates in contraction section step-down, after slow down in expansion segment supercharging.
The Advantageous Effects adopting as above technical scheme to obtain is:
Simply, handling ease, installation cost is lower for band class venturi pipeline section and spindle spoiler construction.When the least possible minimizing Liquid Flow resistance, improve gas-liquid blending effect largely, reinforced foam luminous efficiency.
Accompanying drawing explanation
Fig. 1 is foam-making apparatus structural representation.
Detailed description of the invention
1 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
A kind of foam-making apparatus, comprise blending room 4, the front portion of blending room is class venturi pipeline section 3, the rear portion of blending room is provided with spindle flow spoiler 5, the entrance of blending room is connected with source of the gas and foam solution feedway, and the downstream of spindle is provided with filter screen 6, and the outlet 7 of blending room connects apparatus for spray of foam.After the entrance of gas-liquid two-phase blending room enters blending room, first gas-liquid blending under class venturi pipeline section restrictive function is subject to, then, gas-liquid two-phase runs into the flow-disturbing effect of spindle flow spoiler in downstream, further gas-liquid blending, gas phase inertia is less, rapid break-in flows away from the surrounding of spindle flow spoiler, liquid phase inertia is larger, collide with the windward side of spindle flow spoiler, liquid phase is dispersed into tiny drop or brin, increase in collision area gas-liquid two-phase contact area, at the downstream gas-liquid two-phase of spindle flow-disturbing part through filter screen, further refinement drop and brin, foam solution after blending is through the apparatus for spray of foam of blending room outlet flow to downstream.
The entrance of blending room comprises gas phase entrance 1 and liquid phase entrance 2, and liquid phase entrance is in centre, and gas phase entrance is around liquid phase entrance.The inlet diameter size of blending room is little compared with the diameter of blending room, and gas-liquid two-phase, after entrance enters blending indoor, expansion flowing occurs.
Spindle flow spoiler is welded in blending chamber interior walls by cross frame.
Class venturi pipeline section comprises contraction section and expansion segment, and namely the flow area of class venturi pipeline section first shrinks rear expansion, and gas-liquid two-phase first accelerates in contraction section step-down, after slow down in expansion segment supercharging.Because the density of gas-liquid two-phase is different with flow velocity, enhance gas-liquid blending effect in contraction and expansion segment.Then, run into the flow-disturbing effect of spindle flow-disturbing part in downstream, strengthen gas-liquid blending effect further.Gas-liquid two-phase from expansion segment out after, run into the inhibition of spindle flow-disturbing part, gas phase inertia is less, and rapid break-in flows away from the surrounding of spindle.Liquid phase inertia is comparatively large, and collide with the front of spindle, liquid phase is dispersed into tiny drop or brin, thus increases rapidly in collision area gas-liquid two-phase contact area, and gas-liquid blending effect is better.
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.
