Description
Technical field
The present invention relates to refrigerating field, in particular to a kind of gas-liquid separator.
Background technology
Gas-liquid separator is generally used in medium-sized and large-scale refrigerating system, between evaporator and compressor.Separate gaseous state and
Liquid refrigerant, makes refrigerant enter compressor from compressor air suction mouthful in the form of a vapor, prevents from causing liquid hammer to compressor,
Refrigeration oil is returned simultaneously into compressor, lubricates compressor, it is ensured that the normal operation of compressor, and store some liquid refrigerant.
Market demand for development is answered, product structure updates optimization, and more and more higher is required to product install convenient and miniaturization etc..
As shown in figure 1, gas-liquid separation is main by inlet tube 1, outlet 2, upper end cover 3, body 4, bottom end cover 5, installing plate 6 etc.
Parts are constituted, inlet/outlet pipe one pipeline of formation, up and down end cap and one closed container of formation of body 4.(such as Fig. 2 is extremely for outlet 2
Shown in Fig. 4) frequently with the U-shaped bend pipe 7 with spill port, U-shaped bend pipe 7 is located inside body 4, the port of export 8 of outlet 2
Drawn above end cap, suction end 9 is located inside container, the gas-liquid mixed refrigerant flowed into for anti-locking system is directly entered outlet 2,
Therefore the position of suction end 9 is higher than more than the port of export 11 of inlet tube 1, about pipe diameter.
After gas-liquid mixed refrigerant is flowed into from inlet tube, flowed out by the outlet at bottom end of inlet tube 1, it is still gas-liquid now to flow out moment
Mixed type refrigerant, into after container inside, because gaseous coolant and liquid refrigerants body proportion are different, gaseous coolant is into container
Portion's diffusion is floated, and liquid refrigerants gravity sinks, and gaseous coolant after refrigerant gas-liquid separation, separation is realized using this sedimentation theory
Sucked by the suction end 9 of outlet 2, during by U-shaped 7 10 position of bottom oil return hole of bend pipe, the refrigeration oil of siphon inner chamber is together
Enter from the port of export 8 in compressor.Refrigerant is returned to compressor from compressor air suction mouthful in the form of a vapor, prevent to pressure
Contracting machine causes liquid hammer, while the refrigeration oil being siphoned into plays lubrication to compressor.
There is following shortcoming in gas-liquid separator of the prior art：
1st, designed for the gas-liquid separator of small volume, big pipeline particular system, former scheme u-tube structure is relatively difficult to achieve.As schemed
Shown in 5, φ d and R is into certain proportional relation, and φ d are bigger, and R is bigger, and R is bigger, and A sizes are bigger, that is to say, that separator
Body diameter phi d2 needs are sufficiently large to be fully accommodated in outlet in body, and gas-liquid separator can normal work.Example
Such as：Body diameter≤105mm small-sized gas-liquid separator, outlet maximum gauge is only φ 22.2, when from more than φ 22.2
U-shaped outlet, as seen from Figure 5 U-tube exceed body diameter phi d2 scopes, need to outlet structures design optimization
Product development requirement can be met.
2nd, U-shaped outlet is larger in container interior volume accounting, and capacity utilization declines.Under same isometric(al) design condition, U
The total measurement (volume) of the gas-liquid separator of type tubular construction design is relatively large, and cost is higher.
3rd, the pressure drop of the elbow part of the outlet of U-shape structure is big so that compressor horsepower increase, further causes system
Energy Efficiency Ratio is reduced.
4th, as shown in fig. 6, U-tube wall and body inner distance a=(φ ID-b)/2, wherein ID are body internal diameter, b is U
Type pipe ultimate range, a is U-tube and body inwall distance.If minor diameter body uses the separator of major diameter U-tube,
So size of the U-tube with body inwall apart from a will certainly reduce.A is smaller, when producing vibration when the system is operated, U-tube
It is bigger with body inwall collision probability, it is also easy to produce noise.Simultaneously long-term collision friction can cause U-tube easily damaged, so that
Liquid refrigerants is caused to enter through breakage in compressor.
5th, because bottom is that " u "-shaped shape and end cap assembly direction have uniqueness, therefore U-shaped outlet assembly difficulty is big.Go out in principle
Mouthful end diameter can only be equal or less than raw material size (such as less than raw material size, refrigerant passage is smaller, the increase of system flow resistance,
Therefore do not use typically), if port of export diameter is more than raw material size, the auxiliary member reinforcement such as bushing need to be borrowed, this can cause in cost
Rise and technological process is complicated.
