Description

Technical Field

[0001] The utility model relates to a gas-liquid separator used for refrigeration, belonging to the technical field of refrigeration. Background Art

[0002] When the refrigeration system is overcharged with refrigerant, or the expansion valve is improperly installed or structurally damaged, too much liquid refrigerant will enter the evaporator, causing the gaseous refrigerant discharged from the evaporator to carry excessive liquid refrigerant, resulting in "liquid hammer" in the compressor, which is not conducive to the safe operation of the compressor and may even cause damage. In order to avoid this situation, a gas-liquid separator needs to be installed at the compressor suction port to separate the liquid in the return pipe to prevent liquid hammer in the compressor.

[0003] However, the existing refrigeration system gas-liquid separator has poor gas-liquid separation effect on high-speed airflow, which may cause gas to carry liquid. In order to solve the above problems, corresponding patents have appeared in the industry, such as the authorization announcement number CN221076850U, and the patent name is: A Chinese authorized utility model patent for a horizontal gas-liquid separator. In the above patent, the left air intake branch and the right air intake branch are set to divert the main air intake pipe into the fluid, so that the high-flow gas-liquid two-phase flow refrigerant flows around and slows down from both ends of the cylinder, improving the utilization rate of the space in the separator cylinder, making the overall flow field more uniform and reducing the peak flow rate, which is conducive to faster sedimentation of droplets under the action of gravity, thereby improving the gas-liquid separation efficiency and avoiding liquid carryover.

[0004] However, the above patent has the following problems: the high-velocity gas-liquid mixture is decelerated only by impacting the head, and is discharged from the outlet after deceleration, resulting in the gas-liquid mixture staying in the separator cylinder for too short a time, and the gas flow velocity cannot be reduced, and no liquid collecting structure is provided, resulting in poor gas-liquid separation effect. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a gas-liquid separator for refrigeration to solve the problems faced in the industry.

[0006] In order to solve the above technical problems, the utility model is implemented through the following technical solutions: a gas-liquid separator for refrigeration, comprising a hollow box body, an S-shaped separation structure is arranged in the box body, an air inlet pipe and an air outlet pipe are respectively arranged on the left and right sides of the box body, the air inlet pipe and the air outlet pipe are respectively connected to the S-shaped separation structure, the S-shaped separation structure comprises a first separation pipe, a second separation pipe and a third separation pipe with the same structure, an angle is arranged between the first separation pipe and the second separation pipe, an angle is arranged between the second separation pipe and the third separation pipe, the first separation pipe and the second separation pipe are connected together by a side connecting seat, and the second separation pipe and the third separation pipe are connected together by a side connecting seat.

[0007] Preferably, the first separation pipe is of a rectangular structure, and a plurality of installation grooves are arranged above the first separation pipe. The installation grooves penetrate from the upper surface of the first separation pipe to the interior of the first separation pipe, and a buffer cooling plate is arranged in the installation groove, and absorbent cotton is arranged on the surface of the buffer cooling plate.

[0008] Preferably, the buffer cold collecting plate comprises a plate body, a plurality of exhaust holes are arranged on the plate body, and a supporting boss is arranged on the top of the plate body.

[0009] Preferably, the angle is 30 degrees to 60 degrees.

[0010] Preferably, the side connecting seat comprises a seat body which is hollow inside and has a polygonal structure, and a first opening portion and a second opening portion are provided on the seat body.

[0011] Preferably, a drain outlet is provided at the lower end of the third separation pipe, and a water collecting bucket is provided on the drain outlet.

[0012] Preferably, a box door is provided on the front of the box body, and a handle is provided on the box door.

[0014] Preferably, a support frame is also provided on the outer bottom of the box body.

[0015] Compared with the prior art, the advantages of the utility model are: the gas-liquid mixed gas is introduced into the S-shaped separation structure from the air inlet pipe to increase the residence time of the gas-liquid mixed gas, and then the speed of the high-flow gas-liquid mixed gas is reduced through multiple buffer cooling plates, thereby achieving the purpose of speed reduction. At the same time, when the gas-liquid mixed gas passes through the buffer cooling plate, the moisture in the gas-liquid mixed gas will remain on the buffer cooling plate. Due to the effect of gravity, the moisture on the buffer cooling plate flows along the S-shaped separation structure into the water collecting bucket, thereby achieving the purpose of gas-liquid separation.

DETAILED DESCRIPTION

[0027] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods:

[0028] like Figures 1 to 9 A gas-liquid separator for refrigeration shown in the figure includes a hollow box body 1, an S-shaped separation structure 2 is arranged in the box body 1, an air inlet pipe 101 and an air outlet pipe 102 are respectively arranged on the left and right sides of the box body 1, the air inlet pipe 101 and the air outlet pipe 102 are respectively connected to the S-shaped separation structure 2, the S-shaped separation structure 2 includes a first separation pipe 3, a second separation pipe 4 and a third separation pipe 5 with the same structure, an angle is set between the first separation pipe 3 and the second separation pipe 4, an angle is set between the second separation pipe 4 and the third separation pipe 5, the first separation pipe 3 and the second separation pipe 4 are connected together by a side connecting seat 6, and the second separation pipe 4 and the third separation pipe 5 are connected together by the side connecting seat 6.

[0029] In order to be able to insert the buffer cold collecting plate 7, further, the first separation pipe 3 is of a rectangular structure, and a plurality of installation grooves 301 are arranged above the first separation pipe 3. The installation grooves 301 penetrate from the upper surface of the first separation pipe 3 to the interior of the first separation pipe 3, and the buffer cold collecting plate 7 is arranged in the installation grooves 3.

[0030] like Figure 8 As shown, in order to enable the gas to flow, the buffer cooling plate 7 further includes a plate body 701, a plurality of exhaust holes 702 are arranged on the plate body 701, and a supporting boss 703 is arranged on the top of the plate body 701, so that the installation of the buffer cooling plate 7 can be facilitated by the supporting boss 703.

[0031] In order to enable the water droplets to flow, further, the angle is 30 degrees to 60 degrees.

[0032] In order to connect the pipes, the side connection seat 6 further comprises a seat body 601 which is hollow inside and has a polygonal structure, and a first opening portion 602 and a second opening portion 603 are provided on the seat body 601 .

[0033] In order to collect the moisture, a drain outlet 501 is further provided at the lower end of the third separation pipe 5 , and a water collecting bucket 502 is provided on the drain outlet 501 .

[0034] In order to play a protective role, a box door 103 is further provided on the front of the box body 1, and a handle 104 is provided on the box door 103.

[0035] In order to fix the S-shaped separation structure 2 , a plurality of support rods 105 are further provided in the box body 1 , and the support rods 105 fix the first separation pipe 3 , the second separation pipe 4 , and the third separation pipe 5 to the box body 1 , respectively.

[0036] In order to play a supporting role, a support frame 106 is further provided at the outer bottom of the box body 1 .

[0037] When in use, the gas-liquid mixed gas to be separated is passed through the air inlet pipe 101 into the S-type separation structure 2, and a plurality of buffer cooling plates 7 are inserted into the S-type separation structure 2. The buffer cooling plates 7 are provided with a plurality of exhaust holes 702. After the gas-liquid mixed gas enters the S-type separation structure 2, the gas-liquid mixed gas will pass through the plurality of buffer cooling plates 7, and the speed of the gas-liquid mixed gas will be reduced by the buffer cooling plates 7. Water-absorbent cotton is provided on the surface of the buffer cooling plates 7. When the gas-liquid mixed gas passes through the buffer cooling plates 7, the water mixed in the gas is absorbed by the water-absorbent cotton. After the water-absorbent cotton absorbs the water, the water in the water-absorbent cotton remains in the water-absorbent cotton. At this time, the buffer cooling plates 7 are pulled out of the S-type separation structure 2 and the water-absorbent cotton is replaced.

[0038] At the same time, when the absorbent cotton is in the process of absorbing water, the water in the absorbent cotton will drip from the absorbent cotton to the lower surface of the first separation pipe 3, the second separation pipe 4 and the third separation pipe 5 due to the effect of gravity. Since an angle is set between the first separation pipe 3, the second separation pipe 4 and the third separation pipe 5, the first separation pipe 3, the second separation pipe 4 and the third separation pipe 5 are all inclined, so that the water droplets dripping in the pipe will flow along the first separation pipe 3, the second separation pipe 4 and the third separation pipe 5, and finally flow from the drain port 501 of the third separation pipe 5 to the water collecting bucket 502, thereby realizing the collection of water.

[0039] Through the above method, the gas-liquid mixed gas is introduced into the S-shaped separation structure 2 from the air inlet pipe to increase the residence time of the gas-liquid mixed gas, and then the speed of the high-flow gas-liquid mixed gas is reduced through multiple buffer cooling plates 7, thereby achieving the purpose of speed reduction. At the same time, when the gas-liquid mixed gas passes through the buffer cooling plate 7, the moisture in the gas-liquid mixed gas will remain on the absorbent cotton of the buffer cooling plate 7, and the absorbent cotton can be replaced. At the same time, due to the effect of gravity, part of the moisture on the absorbent cotton flows along the S-shaped separation structure 2 to the water collecting bucket 502, thereby achieving the purpose of gas-liquid separation.

[0040] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
