Speed glides, and drops to the bottom of the inner chamber of housing 100, is unlikely to as the drop that need to be condensed during former plate shaped baffle plate 300 reaches one
Determine degree just to drip, gas carrying liquid phenomenon is blown in reduction.
Specifically, filter bores 310 are distributed on baffle plate 300.Preferably, filter bores 310 are provided with several columns, in each folding
On diagonally downward two sides of turn of bilge, it is respectively provided with one at the crest of the bottom of bending part and the connection of two bending parts and arranged
Filter opening 310.
Further, in addition to the screen pack 400 that is arranged on inside housing 100, screen pack 400 are provided with two, respectively
It is arranged on above and below baffling component.Specifically, the screen pack of lower section is arranged between baffle plate 300 and baffling component.
The utility model also includes a kind of air-conditioning system, and described air-conditioning system includes the sudden strain of a muscle in any of the above-described embodiment
Send out device.
The course of work of above-mentioned flash evaporation is as follows：
The refrigerant of gas-liquid mixed sprays into intracavitary in housing 100 through feed tube 110, and the baffle plate 300 designed by bending enters
The first separation of row, then enters vertical-sprue, absorption and and top plate by baffling side plate from the S-shaped tunnel inlets on bottom plate
With the multiple impacts on floor, the further gas-liquid separation of refrigerant, finally by the escape pipe 130 at top, refrigerant gas fills into
Sencond stage impeller；Drain pipe 120 then draws saturation refrigerant liquid, enters evaporator by the throttling of two-step throttle device.
The utility model targetedly arranges baffling component by studying the mobility status of fluid in flash evaporation, can handle
Traditional baffling mode has made subversive modification, adds baffling number, effectively reduces gas pressure drop in flash evaporation, increase
The turbulence situation of fluid；The baffling side plate being arranged in a vertical direction, it is more beneficial for depending on and falling with liquid gas liquid pearl.Simultaneously
Bending baffle plate 300 increases fluid and the contact area of baffle plate 300, and inclined plate face is advantageous to the autonomous landing of drop, reduced
Brought into the probability of higher height by gas again, tentatively just reaching good separating effect, increase substantially the separation effect of gas-liquid
Rate.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
