Description

Technical Field

[0001] The present invention relates to the technical field of gas-liquid separation, and particularly to a condensing gas-liquid separator. Background Art

[0002] Gas-liquid separation refers to the process of separating liquid components (liquid droplets, mist or vapor) in a mixed gas stream from the gas, and is widely applied in fields such as petrochemical industry, energy environmental protection, pharmaceutical and food industries.

[0003] According to the separation principle, gas-liquid separation is mainly divided into two categories: mechanical separation method and phase change separation method. The mechanical separation method mainly separates liquid droplets through physical means such as inertia, centrifugation, and filtration. However, it is applicable to already formed liquid droplets, has low processing efficiency for tiny liquid droplets, and requires multi-stage series connection. The phase change separation method condenses gaseous components into liquid by cooling, and is applicable to steam or condensable gases. It has high separation purity, but also has high energy consumption. Therefore, in practice, the two are often combined to balance efficiency and economy.

[0004] After retrieval, a Chinese invention patent with the publication number CN105327553B discloses a gas-liquid separation device, which includes a first intake pipe capable of being connected to an oil and gas well; a gas-liquid separation chamber with an air outlet, and the gas-liquid separation chamber is connected to the first intake pipe through a second intake pipe; an outer bellows disposed in the gas-liquid separation chamber, the outer bellows having an opposite outer bellows upper end and outer bellows lower end, and a turning plate is hermetically connected to the upper end of the outer bellows; an inner bellows disposed in the outer bellows, the inner bellows having an opposite inner bellows upper end and inner bellows lower end, and the lower end of the inner bellows is connected to the second intake pipe. This application realizes gas-liquid separation through the collision of gas with the inner wall of the bellows. However, this only separates the already formed liquid droplets in the gas. If the gas contains uncondensed saturated steam, it is difficult to achieve separation; and this method relies on the inertial force of the liquid droplets, but tiny liquid droplets have small mass and are easily deflected by the air flow, so it is difficult to achieve separation by impact. Therefore, this device is difficult to effectively and fully perform gas-liquid separation. Summary of the Invention

[0005] In view of the above-mentioned prior art, the present invention aims to provide a condensing gas-liquid separator, and the main technical problem to be solved is how to effectively and fully perform gas-liquid separation.

[0006] To achieve the above object, the technical solution of the embodiment of the present invention is realized as follows:

[0008] The condensation mechanism includes a number of condensing tubes arranged on the outer side inside the condensation box. The heat conduction mechanism includes a number of baffles arranged on the inner side inside the condensation box.

The condensing tubes rotate to promote the discharge of the liquid droplets obtained by condensation. A mist-catching mechanism is provided on the water tank. The mist-catching mechanism includes a number of wire meshes, and the wire meshes separate the materials by catching the liquid droplets in the gas.

[0009] Furthermore, the top end of the condensation box is fixedly connected with a housing. The top end of the housing is provided with a first opening. The housing is fixedly connected with an air chamber at the first opening. A number of first through holes are equidistantly arranged on the outer side of the bottom end of the air chamber and on the outer side of the top end of the condensation box. The air chamber and the condensation box are rotatably connected with the same feed pipe at the first through holes.

[0010] Furthermore, a number of second through holes are equidistantly arranged on the outer side of the bottom end of the condensation box. The condensation box is rotatably connected with a discharge pipe at the second through holes. The number of the discharge pipes is the same as that of the feed pipes and they are correspondingly arranged one above the other. The condensing tubes are fixedly connected between the correspondingly arranged upper and lower discharge pipes and feed pipes, and the condensing tubes are spiral-shaped.

[0011] Furthermore, a third through hole is provided in the middle of the top end of the condensation box. The condensation box is rotatably connected with a connecting shaft at the third through hole. A turntable is fixedly connected to the top end and the bottom end of the rod body of the connecting shaft outside the condensation box. A number of baffles are equidistantly fixedly connected between the two turntables, and one ends of the a number of baffles away from each other are all arc-shaped.

[0012] Furthermore, the driving mechanism includes a motor. A base is fixedly connected to the middle of the bottom end of the air chamber. The motor is fixedly connected to the bottom end of the base. The bottom end of the output shaft of the motor is fixedly connected with the connecting shaft. The air chamber is in a dome shape, and an air inlet pipe is fixedly connected to the top end of the air chamber.

[0013] Furthermore, a driving wheel is connected to the rod body of the connecting shaft outside the condensation box by a key, and a driven wheel is connected to the rod body of the feed pipe outside the condensation box by a key. The driving wheel meshes with the driven wheel. A second opening is provided on one side of the condensation box. A refrigeration box is fixedly connected to the condensation box at the second opening. A semiconductor refrigeration sheet is arranged in the refrigeration box. A number of heat dissipation openings are provided on one side of the refrigeration box outside the condensation box.

[0014] Furthermore, an air outlet is provided on one side of the top end of the water tank. An air outlet pipe is fixedly connected to the water tank at the air outlet. The air outlet pipe includes a pipe body and a net shell. A notch is provided at the bottom end of the pipe body of the pipe body in the water tank. The net shell is fixedly connected to the pipe body at the notch. A number of wire meshes are equidistantly fixedly connected between the pipe body and the net shell.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By placing the condensation pipe in the cooling medium, the gas-liquid mixture entering the condensation pipe can be in a low-temperature state, and then condensed to achieve gas-liquid separation. Since the baffle plate and the condensation pipe rotate synchronously and in opposite directions, the full contact between the condensation pipe and the cooling medium can be ensured, thus ensuring the condensation effect. Moreover, the rotation of the condensation pipe can also promote the discharge of the droplets formed by condensation inside it, facilitating the collection of the materials after gas-liquid separation. In addition, when the gas-liquid mixture after condensation treatment is discharged from the exhaust pipe, the wire mesh can also capture the droplets still present in the gas. Therefore, the present device can effectively and fully perform gas-liquid separation;

[0019] 2. By setting up the fence and bolts to detachably connect the condensation box and the water tank, the water tank can centrally collect the droplets obtained from gas-liquid separation. Therefore, after the separation is completed, the condensation box and the water tank can be disassembled to centrally obtain the liquid in the water tank, ensuring the convenience of material collection;

[0020] 3. By setting a mesh below the discharge pipe, the mesh holes on the mesh can divide the droplets into multiple smaller droplets when the droplets fall, thereby dispersing the kinetic energy of the water droplets and reducing the degree of splashing when they fall, and thus facilitating the complete collection of the materials.

Detailed implementation manners

[0029] The technical solution of the present invention will be further elaborated in detail below with reference to the drawings in the specification and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0030] Embodiment 1

[0031] Referring to the appendix Figures 1-5 , the present application provides a condensing gas-liquid separator, including a condensing box 1, a water tank 6 and a semiconductor refrigeration sheet. When cooling the cooling medium, an external cold source or a semiconductor refrigeration sheet can be selected. The external cold source is convenient to implement and has stable cooling, meeting the use requirements of chemical engineering devices. By using a semiconductor refrigeration sheet to replace the direct connection to an external cold source (such as circulating cooling water, chilled water or low-temperature coolant, etc.), the pipeline connection outside the device can be reduced, making the use of the device more independent. The condensing box 1 is provided with a cooling medium, and the condensing box 1 is provided with a condensing mechanism, a heat conduction mechanism and a driving mechanism. The semiconductor refrigeration sheet cools the condensing mechanism through the heat conduction mechanism, and the condensing mechanism separates the materials through condensation; the driving mechanism includes a motor 17, and the bottom end of the output shaft of the motor 17 is fixedly connected to the connecting shaft 13.

[0032] The condensation mechanism includes a number of condensation tubes 7 arranged on the outer side inside the condensation box 1. The heat conduction mechanism includes a number of baffles 14 arranged on the inner side inside the condensation box 1. The driving mechanism is used to drive the rotation of the condensation tubes 7 and the baffles 14. The baffles 14 rotate to stir the cooling medium to move and transfer the heat on the condensation tubes 7. The condensation tubes 7 rotate to promote the discharge of the droplets obtained by condensation. A mist-catching mechanism is provided on the water tank 6. The mist-catching mechanism includes a number of wire meshes 1003. The wire meshes 1003 separate the materials by catching the droplets in the gas. Therefore, this device can play a role in separating the gas-liquid mixture twice, that is, first use condensation to promote the conversion of the gaseous substances in the gas into droplets, and after the larger droplets adhere to the condensation tubes 7, use the wire meshes 1003 to continue to catch the smaller droplets to ensure the degree of solid-liquid separation.

[0033] When using this device for gas-liquid separation, coolant can be first injected into the condensation box 1, and then the motor 17 and the semiconductor refrigeration chip are started. The motor 17 drives the driving wheel 18 and the turntable 12 to rotate through the connecting shaft 13. The turntable 12 drives the baffle 14 to rotate to stir the coolant, so that the coolant can be quickly cooled under the action of the semiconductor refrigeration chip.

[0034] Preferably, a driving wheel 18 is connected to the outer rod body of the connecting shaft 13 outside the condensation box 1 by key connection. A driven wheel 20 is connected to the outer rod body of the feed pipe 19 outside the condensation box 1 by key connection. The driving wheel 18 meshes with the driven wheel 20. A second opening is provided on one side of the condensation box 1. A refrigeration box 15 is fixedly connected to the condensation box 1 at the second opening. The semiconductor refrigeration chip is arranged in the refrigeration box 15. A number of heat dissipation openings are provided on the outer side of the refrigeration box 15 outside the condensation box 1. The cold end of the semiconductor refrigeration chip cools the refrigerant through the side wall of the refrigeration box 15 in the condensation box 1. The heat dissipated by the hot end of the semiconductor refrigeration chip will be dissipated from the heat dissipation openings, so as to ensure the smooth operation of the semiconductor refrigeration chip.

[0035] At the same time, the rotation of the driving wheel 18 can also drive the feed pipe 19 to rotate through the driven wheel 20. The feed pipe 19 drives the condensation tubes 7 to rotate, so that they can rotate in the opposite direction to the baffle 14. Therefore, the condensation tubes 7 can be in full contact with the coolant, thus creating a low-temperature environment for the gas-liquid mixture.

[0036] Preferably, a base 16 is fixedly connected to the middle of the bottom end of the gas chamber 3. The motor 17 is fixedly connected to the bottom end of the base 16. The gas chamber 3 is in a dome shape. An air inlet pipe 4 is fixedly connected to the top end of the gas chamber 3.

[0037] Preferably, a housing 2 is fixedly connected to the top end of the condensation box 1. A first opening is provided at the top end of the housing 2. An air chamber 3 is fixedly connected to the housing 2 at the first opening. A plurality of first through holes are equidistantly provided on the outer side of the bottom end of the air chamber 3 and on the outer side of the top end of the condensation box 1. A same feed pipe 19 is rotatably connected to the air chamber 3 and the condensation box 1 at the first through holes.

[0038] After the condensation pipe 7 is pre-cooled, the gas-liquid mixture can be introduced from the intake pipe 4, so that it fills the air chamber 3 and enters the condensation pipe 7 from the feed pipe 19. Since the condensation pipe 7 is spiral and its internal environment is low temperature, the gas-liquid mixture flowing inside it will condense to generate liquid droplets, thereby achieving the effect of gas-liquid separation.

[0039] Preferably, a third through hole is provided in the middle of the top end of the condensation box 1. A connecting shaft 13 is rotatably connected to the condensation box 1 at the third through hole. At the top and bottom of the rod body of the connecting shaft 13 in the condensation box 1, turntables 12 are fixedly connected. A plurality of baffle plates 14 are equidistantly fixedly connected between the two turntables 12. The mutually remote ends of the plurality of baffle plates 14 are all arc-shaped. The arc-shaped ends of the baffle plates 14 can have greater resistance when rotating in the refrigerant, so that the refrigerant can be more fully stirred to generate relative movement with the condensation pipe 7.

[0040] And during this process, the baffle plates 14 stirring the coolant can maintain the low-temperature environment in the condensation pipe 7 to ensure the condensation effect, while the rotation of the condensation pipe 7 can promote the outflow of the liquid droplets formed by condensation inside it, so as to facilitate the collection of the materials after gas-liquid separation.

[0041] Preferably, an air outlet is provided on one side of the top end of the water tank 6. An outlet pipe 10 is fixedly connected to the water tank 6 at the air outlet. The outlet pipe 10 includes a pipe body 1001 and a mesh shell 1002. A notch is provided at the bottom end of the pipe body 1001 in the water tank 6. The mesh shell 1002 is fixedly connected to the pipe body 1001 at the notch. A plurality of wire meshes 1003 are equidistantly fixedly connected between the pipe body 1001 and the mesh shell 1002. After the wire meshes 1003 capture the small liquid droplets in the gas, the liquid droplets will flow downward along the surface of the wire meshes 1003 due to their own gravity, so they will fall from the mesh shell 1002 to facilitate the centralized collection of materials.

[0042] After that, the liquid droplets separated from the solid-liquid mixture will flow out from the discharge pipe 11 and drip into the water tank 6 due to their own gravity, while the gas will be in the top space in the water tank 6 and be discharged from the outlet pipe 10. And the wire meshes 1003 can capture the small liquid droplets still present in the gas during the process of the gas flowing through the outlet pipe 10, so as to ensure the degree of gas-liquid separation.

[0043] Preferably, a base 5 is fixedly connected to the bottom end of the water tank 6, and a fence 9 is fixedly connected to the bottom end of the condensation box 1 on the outer side of the water tank 6. A number of threaded through holes are equidistantly formed on the outer side of the fence 9, and a bolt 8 is threadedly connected to the fence 9 at the threaded through holes.

[0044] After the gas-liquid mixture is processed, the condensation box 1 can be removed from the water tank 6 after loosening the bolt 8. At this time, the water tank 6 is in an open state, so that the centralized extraction of materials can be facilitated.

[0045] Embodiment 2

[0046] Referring to the appendix Figure 6 In this application, a condensing gas-liquid separator is provided. Compared with Embodiment 1, in order to prevent droplets from splashing when falling, a guide plate 21 is fixedly connected to the inner wall of the water tank 6 below the discharge pipe 11. The guide plate 21 is in an inclined state. A third opening is formed in the plate body of the guide plate 21 below the discharge pipe 11. A mesh 22 is fixedly connected to the guide plate 21 at the third opening. The material of the mesh 22 is plastic. The plastic mesh 22 does not absorb water, so that droplet loss can be avoided, thereby ensuring the integrity of material extraction.

[0047] When droplets fall at the discharge pipe 11, the mesh 22 can catch the droplets and divide them into several smaller droplets by using the mesh holes. Therefore, the kinetic energy of the droplets when falling can be dispersed, avoiding splashing and resulting in incomplete material extraction. In addition, since the mesh 22 is in an inclined state, it can promote the droplets to fall, facilitating material collection.

[0048] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered by the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
