Description

[0002] A gas-liquid separator is installed between the evaporator and the compressor of the air conditioner. Its function is to separate the liquid droplets in the medium to prevent the droplets from entering the compressor and causing damage to the compressor.

[0003] When in use, the existing gas-liquid separators will mostly use an oil-blocking cover to block the mixed refrigerant and oil entering the gas-liquid separator. There are also small droplets in the gaseous refrigerant itself. At the same time, small droplets will be formed after the liquid refrigerant collides with the oil-blocking cover, thereby increasing the number of small droplets in the gas-liquid separator. When the small droplets move to the pipe opening of the intake pipe, the extraction pressure of the compressor causes the small droplets to be directly sucked into the intake pipe and enter the compressor, reducing the effect of gas-liquid separation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Under the suction action of the compressor, the gaseous refrigerant can enter the connecting pipe through the gap between the third guide plates, and be transported to the compressor through the air outlet pipe and the oil and gas suction pipe. Since the outer side of the third guide plate is provided with a downward-bending shielding structure for shielding the area between the two groups of third guide plates, the gaseous refrigerant will move upward and then downward when moving in the space between the third guide plates, so that the moving direction of the gaseous refrigerant changes, and the small particle droplets carried in the gaseous refrigerant will collide with the third guide plate under the action of inertia. After the small particle droplets come into contact with the third guide plate, they will gather on the third guide plate and be separated from the gaseous refrigerant, thereby reducing the liquid content in the gaseous refrigerant and realizing gas-liquid separation.

[0015] 2. The gaseous refrigerant moves upward along the connecting pipe. Due to the presence of the first guide plate, the movement path of the gaseous refrigerant becomes smaller and the flow speed increases, so that the gaseous refrigerant can push the first rotating shaft to rotate through the first fan blade, and the second rotating shaft drives the blowing component to operate, so that the blowing component blows air downward from the end around the connecting pipe, so that a circular downward-flowing air flow area is formed at the end of the connecting pipe, and the air flow area covers the third guide plate, so that the gaseous refrigerant will be exerted with a downward force by the downward-flowing air before entering the third guide plate, thereby increasing the flow speed of the gaseous refrigerant entering the third guide plate, making the droplets carried in the gaseous refrigerant move faster, further increasing the probability of the droplets contacting the third guide plate, and improving the effect of gas-liquid separation. At the same time, the downward-flowing air will blow the droplets carried in the gaseous refrigerant directly downward away from the area entering the third guide plate, further reducing the liquid content entering the third guide plate, and further improving the effect of gas-liquid separation.

[0016] 3. After the gaseous refrigerant flows out from between the third guide plates, it will collide with the condensation cylinder, causing the residual droplets in the gaseous refrigerant to contact and separate from the condensation cylinder. The spiral blades rotate to allow the liquid gathered on the surface of the condensation cylinder to quickly move downward into the collection cylinder, reducing the contact time between the liquid and the gaseous refrigerant, further improving the gas-liquid separation effect. At the same time, the gaseous refrigerant will also contact the spiral blades when it rises. The rotation of the spiral blades can exert a downward force on the gaseous refrigerant, further causing the residual droplets in the gaseous refrigerant to separate downward from the gaseous refrigerant, further improving the gas-liquid separation effect.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1-Figure 8 As shown, a gas-liquid separator for refrigeration with waste heat recycling function provided by the present invention comprises a shell 1, a gas-liquid inlet pipe 7 and an oil-gas suction pipe 6 are connected on the shell 1, a first guide plate 8 for shielding the gas-liquid inlet pipe 7 is fixedly installed in the shell 1, a partition plate 2 is fixedly installed in the shell 1, a gas-liquid separation cylinder 3 is fixedly installed on the partition plate 2, an air outlet pipe 4 and an air inlet pipe 5 are arranged in the air-liquid separation cylinder 3, the air outlet pipe 4 is connected to the bottom of the air inlet pipe 5, the air outlet pipe 4 is connected to the oil-gas suction pipe 6, and a connecting pipe 9 is connected to the end of the air inlet pipe 5;

[0029] A second guide plate 10 with an inverted funnel structure is fixedly installed inside the vertical section of the connecting pipe 9, a support plate 11 is fixedly installed inside the vertical section of the connecting pipe 9, a first rotating shaft 12 is rotatably installed on the support plate 11, the first rotating shaft 12 is coaxially arranged with the first guide plate 8 and passes through the second guide plate 10, a plurality of groups of first fan blades 13 located in the vertical section of the first guide plate 8 are fixedly installed on the first rotating shaft 12, a plurality of groups of third guide plates 21 are arranged at the end of the connecting pipe 9, the third guide plates 21 are fixedly installed at the end of the connecting pipe 9, the third guide plates 21 are truncated, and the plurality of groups of third guide plates 21 are mutually connected The third guide plates 21 are arranged parallel to and coaxially with the connecting pipe 9, and are fixedly connected to each other. The bottom of a group of third guide plates 21 away from the connecting pipe 9 is in a closed state. A downwardly bent shielding structure for shielding the area between the two groups of third guide plates 21 is provided on the outer side of the third guide plate 21. A blowing assembly 34 driven by the first rotating shaft 12 is provided on the connecting pipe 9. When the first rotating shaft 12 rotates, the blowing assembly 34 blows air downward around the end of the connecting pipe 9. A heat exchange tube 33 is fixedly installed in the area of ​​the shell 1 away from the gas-liquid separation cylinder 3, and both ends of the heat exchange tube 33 extend into the shell 1.

[0030] In actual application of this embodiment, the gas-liquid mixed refrigerant and oil enter the shell 1 through the gas-liquid inlet pipe 7, and then the gas-liquid mixed refrigerant and oil contact and collide with the first guide plate 8 and flow along the first guide plate 8. The liquid refrigerant and oil can flow downward along the first guide plate 8 to the inner wall of the shell 1 and finally fall to the bottom of the shell 1, avoiding the gas-liquid mixed refrigerant and oil directly impacting the liquid refrigerant and oil at the bottom of the shell 1. The gaseous refrigerant floats in the upper part of the shell 1. Under the suction action of the compressor, the gaseous refrigerant can enter the connecting pipe 9 through the gap between the third guide plate 21, and be transported to the compressor through the air outlet pipe 4 and the oil and gas suction pipe 6. The compressor is provided with a shielding structure bent downward for shielding the area between the two groups of third guide plates 21, so that the gaseous refrigerant moves upward and then downward in the space between the third guide plates 21, so that the moving direction of the gaseous refrigerant is changed, and the small particle droplets carried in the gaseous refrigerant will collide with the third guide plate 21 under the action of inertia. After the small particle droplets contact the third guide plate 21, they will gather on the third guide plate 21 and separate from the gaseous refrigerant, thereby reducing the liquid content in the gaseous refrigerant and realizing gas-liquid separation. The liquid gathered on the third guide plate 21 will flow downward to the bottom of the third guide plate 21 at the bottom;

[0031] Afterwards, the gaseous refrigerant moves upward along the connecting pipe 9. Due to the presence of the first guide plate 8, the movement path of the gaseous refrigerant becomes smaller and the flow speed increases, so that the gaseous refrigerant can push the first rotating shaft 12 to rotate through the first fan blade 13. When the first rotating shaft 12 rotates, it drives the blowing component 34 to operate, so that the blowing component 34 blows air downward from the end around the connecting pipe 9, so that a circular downward-flowing air flow area is formed at the end of the connecting pipe 9, and the air flow area covers the third guide plate 21, so that the gaseous refrigerant will be exerted with a downward force by the downward-flowing air before entering the third guide plate 21, thereby increasing the flow speed of the gaseous refrigerant entering the third guide plate 21, and making the droplets carried in the gaseous refrigerant move faster, further The probability of contact between the droplets and the third guide plate 21 is increased, and the effect of gas-liquid separation is improved. At the same time, the downwardly flowing air will blow the droplets carried in the gaseous refrigerant directly downward away from the area entering the third guide plate 21, further reducing the liquid content entering the third guide plate 21, and further improving the effect of gas-liquid separation. The gaseous refrigerant is further dried by the desiccant when flowing in the oil-gas suction pipe 6. The oil and liquid refrigerant will pass through the filter made of nylon material and enter the oil-gas suction pipe 6 through the oil return hole at the bottom of the gas-liquid separation cylinder 3, so that the liquid with waste heat output by the condenser or the high-temperature and high-pressure gas discharged by the compressor passes through the heat exchange tube 33, thereby using the heat of the medium flowing through the heat exchange tube 33 to exchange heat with the area where the gas-liquid separation cylinder 3 is located, thereby realizing the utilization of waste heat.

[0033] Specifically, the blowing assembly 34 also includes a second rotating shaft 15, which is rotatably mounted on the side wall of the connecting pipe 9 and distributed along the radial direction of the connecting pipe 9. The second rotating shaft 15 is rotatably connected to the first rotating shaft 12 through the meshing first bevel gear 14 and the second bevel gear 16. The second rotating shaft 15 extends into the air collecting cylinder 18 and is coaxially arranged with the air collecting cylinder 18. The second fan blade 17 is fixedly mounted on the second rotating shaft 15.

[0034] In actual application of this embodiment, when the first rotating shaft 12 rotates, the second rotating shaft 15 is driven to rotate through the meshing first bevel gear 14 and the second bevel gear 16, and the second rotating shaft 15 drives the second fan blade 17 to rotate, thereby pushing the air in the air collecting cylinder 18 to move into the connecting ring 19, and the air in the shell 1 is replenished into the air collecting cylinder 18 through the gap between the air collecting cylinder 18 and the connecting pipe 9, and the air in the air intake connecting ring 19 is blown downward through the blowing hole 20 to form a circular air flow area.

[0035] like Figure 2-Figure 7 As shown, a gas-liquid separator for refrigeration with a waste heat recycling function provided by the present invention is provided. A condensation cylinder 22 is fixedly installed on the support plate 11. The condensation cylinder 22 is coaxially arranged with the third guide plate 21 and the condensation cylinder 22 extends into the third guide plate 21. A gap is provided between the inner side surface of the third guide plate 21 and the surface of the condensation cylinder 22. A rotating plate 23 is rotatably installed on the condensation cylinder 22. The rotating plate 23 is coaxially arranged with the condensation cylinder 22 and the diameter of the rotating plate 23 is larger than the inner diameter of the third guide plate 21. A spiral blade 25 is fixedly installed on the rotating plate 23. The spiral blade 25 is in sliding contact with the inner surfaces of the condensation cylinder 22 and the third guide plate 21, and the rotating plate 23 is rotatably connected to the first rotating shaft 12.

[0036] Specifically, a third rotating shaft 26 is rotatably installed on the support plate 11. The third rotating shaft 26 passes through the support plate 11 and is parallel to the first rotating shaft 12. The third rotating shaft 26 is rotatably connected to the first rotating shaft 12 through the first gear set 27. The third rotating shaft 26 is rotatably connected to the rotating plate 23 through the second gear set 28. The rotation speed of the rotating plate 23 is less than the rotation speed of the first rotating shaft 12.

[0037] Specifically, a reciprocating screw 29 is rotatably installed in the condensation cylinder 22, and the reciprocating screw 29 is fixedly connected to the lower end of the spiral blade 25. The end of the reciprocating screw 29 away from the condensation cylinder 22 is rotatably connected to a collecting cylinder 31 fixedly installed on the third guide plate 21. The collecting cylinder 31 is fixedly connected to a group of third guide plates 21 away from the connecting pipe 9 and closes the lower end of the group of third guide plates 21.

The bottom of the collecting cylinder 31 is connected to a drain pipe 32, and a one-way valve is provided on the drain pipe 32.

[0038] In actual application of this embodiment, when the first rotating shaft 12 rotates, the rotating plate 23 is driven to rotate through the third rotating shaft 26, and then the spiral blades 25 and the reciprocating screw 29 are driven to rotate. After the gaseous refrigerant flows out from between the third guide plates 21, it will collide with the condensation cylinder 22, so that the residual droplets in the gaseous refrigerant contact and separate from the condensation cylinder 22. The spiral blades 25 rotate so that the liquid gathered on the surface of the condensation cylinder 22 quickly moves downward into the collecting cylinder 31, reducing the contact time between the liquid and the gaseous refrigerant, further improving the gas-liquid separation effect. At the same time, the gaseous refrigerant will also contact the spiral blades 25 when it rises. The rotation of the spiral blades 25 can exert a downward force on the gaseous refrigerant, further causing the residual droplets of the gaseous refrigerant to separate downward from the gaseous refrigerant, further improving the gas-liquid separation effect.

[0039] When the reciprocating screw 29 rotates, it drives the pressure plate 30 to move reciprocatingly up and down. When the pressure plate 30 moves upward, the liquid gathered on the condensation cylinder 22 can flow downward to the bottom of the collecting cylinder 31. When the pressure plate 30 moves downward, the liquid at the bottom of the collecting cylinder 31 is pressed out through the drain pipe 32, thereby preventing the gaseous refrigerant from entering the connecting pipe 9 from below, realizing the timely removal of the liquid in the collecting cylinder 31 and reducing the contact time between the gaseous refrigerant and the liquid.
