The specific embodiment

See also Fig. 1 and Fig. 2, the utility model gas and oil separating plant is to be applied to a cooling system, and this cooling system includes a compressor 30, a condenser 40, an expansion valve 50 and a full-liquid type heat exchanger 60.Compressor 30 is provided with an oil groove 31 that holds lubricating oil, and condenser 40 is connected with compressor 30 by gas and oil separating plant.Expansion valve 50 is connected with condenser 40.Full-liquid type heat exchanger 60 is connected with expansion valve 50 and compressor 30, forms a closed circuit whereby.

The pipeline that gas and oil separating plant is with compressor 30, compressor are discharged fluid (refrigerant) is connected, in order to isolate the lubrication molecule in the lubricating oil that comes from compressor 30 and the fluid that refrigerant mixes.

See also Fig. 3 and Fig. 4, this gas and oil separating plant includes one and collects case 10, an inflow pipe 11, an outflow tube 12, a baffle plate 15, two fixed mounts and two filter assemblies 131,141.

This collection case 10 is a hollow and have a room that is used to collect oil gas, and can constitute by 101,102 of the end caps that a portion 100 and two is arranged at 100 liang of openends of a portion, on collection case 10 bottoms, be formed with at least one oil-out that is communicated with room 103,104, so that release outside the collection case 10 for lubricating oil, oil-out 103,104 can connect an oil pipe 32, and these oil pipe 32 1 ends are connected to compressor 30 and are back to compressor 30 with the lubricating oil that will collect case 10.

See also Fig. 4, this inflow pipe 11 is curved and have a curved channel, and runs through to be arranged on and collect on case 10 1 end caps 101, and when the fluid that mixes with refrigerant when lubricating oil entered inflow pipe 11, the oil gas impact that vicidity is high also attached to the curved channel inwall.The outer openend of inflow pipe 11 is to be positioned to collect outside the case 10, and connects the pipeline that this compressor 30 is discharged the fluid refrigerant, as shown in Figure 1.The inner opening end of inflow pipe 11 is to be positioned at room, near the room bottom, and towards the room inwall.

This outflow tube 12 is curved and have a curved channel, and runs through to be arranged on and collect on case 10 another end caps 102 and relative with inflow pipe 11, and the outer openend of outflow tube 12 is to be positioned to collect outside the case 10, and the inner opening end is to be positioned at room and close room top.

This baffle plate 15 is horizontally installed on the room top of collecting in the case 10, and between inflow pipe 11 and outflow tube 12.

This fixed mount is to be horizontally installed in the room, one fixed mount is between inflow pipe 11 and baffle plate 15, another fixed mount is then between baffle plate 15 and outflow tube 12 pipes, and each fixed mount includes two separately

horizontal web plates

13,14, is formed with several meshes on each

web plate

13,14.

This filter assemblies the 131, the 141st is separately positioned between two

web plates

13,14 of corresponding fixed mount, filter assemblies 131,141 is made with highdensity filter material, when gaseous mixture during by filter assemblies 131,141, filter assemblies 131,141 adsorbable oil gas, and the cooling gas is by its hole order.In addition, the filter assemblies 131 hole orders of close inflow pipe 11 provide multi-level hydrocarbon filter effect whereby greater than the filter assemblies 131 hole orders near outflow tube 12.

Shown in the arrow of Fig. 4, the fluid that mixes with refrigerant when lubricating oil is during by inflow pipe 11, contacting with inflow pipe 11 tube walls earlier attaches on the tube wall oil molecule, this is the separation oil and gas first time, impact end cap 101 walls again, make oil gas attach to wall simultaneously, then fluid is by near the filter assemblies 131 the inflow pipe 11, this is the separation oil and gas second time, follow fluid impact baffle plate 15, with slowing down fluid speed, and can drip simultaneously in collecting case 10 belows because of the gravity effect when making the bigger oil molecule of proportion walk around baffle plate 15 downwards, this is separation oil and gas for the third time, then fluid passes through another filter assemblies 141, this is the 4th separation oil and gas, the inner opening end that climbs at last and enter outflow tube 12, oil gas attaches to inflow pipe 11 tube walls in the process of turnover collection case 10, end cap 101 walls, baffle plate 15 and filter assemblies 131,141, and if having remnants also because of oil gas proportion than refrigerant proportion height, so oil gas falls within the room bottom downwards in the process of climbing, this is the 5th separation oil and gas.

By above-mentioned technological means, the fluid-mixing that comes from compressor can be gone out oil molecule and produce highly purified refrigerant by the gas and oil separating plant multiple times of filtration, it can be avoided lubricating oil to advance in closed circuit and reduce refrigerant and extraneous heat exchanger effectiveness, the running power of compressor is also descended but still keeps the suitable operational effectiveness of cooling system, therefore, the cost of cooling system can decline to a great extent.
