Description
Technical field
The present invention relates to a kind of refrigerating system with novel dispenser.
Background technology
Knockout claims again liquid distributor, is an auxiliary equipment between expansion valve and evaporimeter in refrigeration system, and its effect is that expansion valve cold-producing medium two-phase mixture is out assigned to evenly, equally in each road coil pipe of evaporimeter and is gone.Because efficient knockout can improve the heat exchange property of evaporimeter, and then promote the service behaviour of whole refrigeration system, knockout is generally applied in various refrigeration systems.
On market, existing knockout is mainly pressure-drop type and Venturi type.These two kinds of equal existent defects of knockout.The utilization of pressure-drop type knockout evenly mixes two of gas-liquids to flowing into the method for the two phase flow throttling of knockout, thereby makes separatory even.Therefore in pressure-drop type knockout, have a restrictor ring, two phase flow is larger by the pressure drop of knockout.Venturi type knockout mixed effect is not good, and separatory effect is good not as good as pressure-drop type.
Summary of the invention
The object of the invention is to overcome the defect of existing knockout, propose a kind of knockout of novel structure, make cold-producing medium distributed uniform, reduce the pressure drop causing by knockout, reduce noise of equipment simultaneously.
For achieving the above object, the present invention adopts following technical scheme: a kind of refrigerating system with knockout, comprise the compressor, condenser, expansion valve, knockout and the evaporimeter that connect in turn, described knockout comprises cylindrical shell, described cylinder body bottom is provided with grafting through hole, top is provided with some perforates, in described grafting through hole, is further provided with gas-liquid two-phase inlet tube, is further provided with some gas-liquid two-phase outlets on described top drilling.
Further, the inwall of described cylindrical shell forms hybrid chamber, and cavity has roof and the bottom of arc.
Further, described gas-liquid two-phase outlet is evenly distributed on cylindrical shell top.
Further, described cylindrical shell and gas-liquid two-phase inlet tube are coaxial.
Further, described gas-liquid two-phase outlet is capillary.
Further, described cylindrical shell and several gas-liquid two-phase outlet symmetry axis are coaxial.
Further, the radius R of described cylindrical shell top arc is greater than 1/2 of barrel diameter D.
Further, described inlet tube can be once-through type, rotary-type, ejection-type.
Compared with prior art, the present invention has following beneficial effect: utilize recirculate mixing technology, and separated gradually at various height by the drop of friction speed in the two phase flow of inlet tube; Part two phase flow arrives cylindrical shell upper end, along cylinder inboard wall, refluxes, and in cylindrical shell lower end and part inlet streams, is mixed to form Secondary Flow; The isolated droplets mixing of Secondary Flow and differing heights, flows out from outlet, and gas-liquid two-phase is mixed, and has reduced the pressure drop in mixed process; Because cylindrical shell, inlet tube and outlet, all by being welded to connect, have reduced the matching problem between movable part, can not produce the unfavorable vibratory impulse problem causing of cooperation due to moving component simultaneously, reduce noise.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the invention will be further described.
Refer to shown in Fig. 1 to Fig. 6, a kind of refrigerating system with knockout, comprise the compressor 10, condenser 20, expansion valve 30, knockout 50 and the evaporimeter 40 that connect in turn, described knockout comprises cylindrical shell 51, described cylinder body bottom is provided with grafting through hole, and top is provided with some perforates, in described grafting through hole, is further provided with gas-liquid two-phase inlet tube 52, on described top drilling, be further provided with some gas-liquid two-phase outlets 53, described gas-liquid two-phase outlet is capillary.Described cylindrical shell and gas-liquid two-phase inlet tube are coaxial; Described cylindrical shell and several gas-liquid two-phase outlet symmetry axis are coaxial.Between described cylindrical shell, inlet tube and outlet, all by welding manner, connect.
The inwall of described cylindrical shell 51 forms hybrid chamber, and cavity has roof and the bottom of arc, and gas-liquid two-phase outlet is evenly distributed on cylindrical shell top.The radius R of described cylindrical shell top arc is greater than 1/2 of barrel diameter D.
Described inlet tube can be once-through type, rotary-type, ejection-type.
In the present invention, working medium becomes the gaseous state of HTHP in compressor 10 after overcompression, then enters in condenser 20 and carries out condensation, becomes supercooled state, then passes through the throttling action of expansion valve 30, becomes biphase gas and liquid flow and enters knockout 50.Working medium enters evaporimeter 40 after by knockout equably.Liquid enters evaporimeter 40, through heat absorption, becomes overheated gas, flows into compressor 10, completes circulation.
The cold-producing medium of gas-liquid two-phase upwards pours knockout from gas-liquid two-phase entrance 52, the particle of friction speed is progressively separated at differing heights, part inlet streams impacts to knockout top and refluxes along cylindrical shell 51 inwalls, liquid backflow to cylindrical shell 51 lower ends are risen lower end liquid level, the partially liq that covers gas-liquid two-phase inlet tube 52 mixes with part inlet streams, form Secondary Flow, gas-liquid separated with differing heights in Secondary Flow uphill process is mixed again, reaches outlet 53 and flows out.
Knockout inlet tube can adopt various ways: once-through type, rotary-type, ejection-type.Rotary-type entrance makes inlet streams rotation, and part inlet streams, in the process rising, is thrown toward surrounding under the effect of centrifugal force, strengthens mixing.Ejection-type entrance sprays part inlet streams to surrounding, strengthen mixing.
In the present invention, owing to refluxing, mix with inlet streams and to produce Secondary Flow, Secondary Flow again in uphill process progressively with separated gas-liquid mixed, two mixing of gas-liquid in cylindrical shell are quite even, outlet flowed even.Because the noise that does not have the vibrations that can avoid cold-producing medium to impact generation of active installation division part to cause.What there is no throttle mechanism can reduce the pressure drop in separatory process greatly.The two phase refrigerant evaporimeter of flowing through uniformly, can make full use of disengagement area, improves performance of evaporator.In the situation that refrigerating capacity is constant, the mass flow of the evaporimeter of flowing through reduces.The in the situation that of identical heat exchange amount, the volume of evaporimeter reduces.
