Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and more particularly to an air-water separation device. Background Technology

[0002] Today, ships are equipped with various types of air compressors and air cylinders, which are crucial for operation and maintenance, making venting particularly important. Due to the high humidity at sea, the vented air often contains a large amount of condensate. From a design perspective, the mixture vented from air compressors / air cylinders carries significant pressure and cannot be directly vented to the local area. Direct venting into the tanks could lead to unpredictable consequences such as overpressure of structural compartments. Therefore, separating the gas and water in the vented mixture is of paramount importance.

[0003] There are currently two conventional technical solutions: The first is to install a standard gas-liquid separator in the venting pipeline, relying on gravity settling to separate the gas and liquid based on their different densities. The second is to add a venting buffer tank, where various venting processes are collected. Gas in the mixture is released through the opening of the venting buffer tank, while liquid in the mixture is released from the bottom. However, both of these technical solutions have drawbacks: In the first solution, the standard gas-liquid separator only separates gas and water through gravity settling, resulting in low separation efficiency and incomplete separation; in the second solution, each user's venting requires a designated buffer tank, leading to long pipelines, high costs, and indiscriminate release of gas, which may contaminate the cabin environment due to oil content. Furthermore, its applicability is limited; gases such as nitrogen, which are prohibited from local free release, are not suitable for this open venting method. Summary of the Invention

[0004] In view of the problems of low separation efficiency, incomplete gas-water separation, pollution, and limited applicability of the existing gas-water separation devices, the present invention provides a gas-water separation device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A gas-liquid separator includes a cover and a housing, the cover and the housing being detachably connected; a connecting cylinder is provided on one side of the cover and a first vent is provided on the other side; several layers of first baffles are provided inside the connecting cylinder, each of the first baffles having several flow gaps, and the flow gaps in adjacent first baffles are staggered; an inlet is provided on one side of the housing and a second vent is provided at the bottom; the housing is fitted over the connecting cylinder, and there is a gap between the housing and the connecting cylinder.

[0007] Furthermore, the upper part of the housing is tubular and the lower part is conical. The top of the housing is connected to the cover via a flange, and there is a seal between the housing and the cover.

[0008] Furthermore, an inlet pipe is connected to one side of the upper part of the housing, and the end of the inlet pipe has a flange; a second connecting pipe is connected to the bottom of the housing, and the end of the second connecting pipe has a flange.

[0009] Furthermore, a second annular baffle is fixed between the upper and lower parts of the housing. The second baffle has a through hole, and the through hole is along the same axis as the second connecting pipe.

[0010] Furthermore, the bottom of the connecting cylinder is located below the inlet, and the connecting cylinder is connected to the outside through the first vent.

[0011] Furthermore, the top of the cover is connected to an L-shaped first connecting pipe, the end of which has a flange.

[0012] Furthermore, the first baffle has a plurality of blocks, one end of which is fixedly connected to the inner wall of the connecting cylinder, and the other side forms the flow gap with the adjacent block.

[0013] Furthermore, the outer side of each of the blocks is rectangular, a flow area is formed between adjacent blocks and the connecting cylinder, and the inner side of each block is triangular.

[0014] Furthermore, each of the first baffles has four blocks, and there is a 45° angle between adjacent first baffles.

[0015] Furthermore, each of the first baffles is umbrella-shaped.

[0016] The beneficial effects of this invention are: this invention utilizes the first baffle and the second baffle to achieve multiple separations of the gas-water mixture, which is beneficial to improving the separation efficiency. Furthermore, the first baffle is umbrella-shaped, which can further separate the water in the gas-water mixture, which is beneficial to improving the separation effect. At the same time, this invention can be applied to the separation of gas and water released from air, steam, nitrogen, etc., and has a wide range of applications. Attached Figure Description

[0021] This invention provides a gas-liquid separation device, and one embodiment of the invention is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the gas-liquid separator includes a cover 1 and a housing 5. The top of the cover 1 is connected to an L-shaped first connecting pipe 2, the end of which has a flange and a first vent. The bottom of the cover 1 is provided with a connecting cylinder 3, which communicates with the outside through the first vent. The connecting cylinder 3 contains several layers of first baffles 4, each baffle 4 being umbrella-shaped. Figure 2 and Figure 3 As shown, each first baffle 4 has several inclined blocks 401. The outer ends of the blocks 401 are fixedly connected to the inner wall of the connecting cylinder 3. The outer side of each block 401 is rectangular, and an approximately fan-shaped flow area 403 is formed between adjacent blocks 401 and the inner wall of the connecting cylinder 3. The inner side of each block 401 is triangular, and a flow gap 402 is formed between the inner sides of adjacent blocks 401. Each layer of first baffles 4 is arranged from top to bottom inside the connecting cylinder 3, and the flow gaps 402 and flow areas 403 in adjacent layers of first baffles 4 are staggered. In this embodiment, each baffle has four blocks 401, and there is a 45° angle between adjacent first baffles 4, that is, the lower first baffle 4 rotates at a 45° angle relative to the upper first baffle 4, so that the flow gaps 402 and flow areas 403 of the upper baffle are blocked by the lower blocks 401.

[0023] The upper part of the casing 5 is tubular, and the lower part is conical. An inlet pipe 7 is fixedly connected to one side of the upper part of the casing 5. The inlet pipe 7 has an inlet and a flange at its end. A second connecting pipe 8 is connected to the bottom of the casing 5. The second connecting pipe 8 has a second vent and a flange at its end. An annular second baffle 6 is fixed between the upper and lower parts of the casing 5. The second baffle 6 has a through hole, which is arranged along the same axis as the second connecting pipe 8.

[0024] The upper part of the housing 5 is fitted over the connecting cylinder 3, and there is a gap between the inner wall of the housing 5 and the outer wall of the connecting cylinder 3. The top of the housing 5 is detachably fixed to the cover 1 via a flange to form a receiving cavity, and there is a seal between the housing 5 and the cover 1 to prevent leakage after the gas-water mixture enters the receiving cavity. The bottom end of the connecting cylinder 3 is located below the inlet pipe 7. The through holes of the first connecting pipe 2, the second connecting pipe 8, the connecting cylinder 3, and the second baffle 6 are arranged along the same axis.

[0025] like Figure 4 As shown, the inlet pipe 7 is connected to the vent pipe of components such as the air compressor and air cylinder via a flange. After the gas-water mixture enters the receiving cavity through the inlet of the inlet pipe 7, it moves downward along the gap channel formed between the inner wall of the shell 5 and the outer wall of the connecting cylinder 3. After being blocked by the second baffle 6, the denser water in the gas-water mixture will enter the lower part of the shell 5 through the through hole of the second baffle 6 and flow out of the receiving cavity through the second vent of the second connecting pipe 8, thus forming the first separation. Then the gas-water mixture enters the connecting cylinder 3 upward. Several layers of inclined baffles are arranged from top to bottom in the connecting cylinder 3, and the flow gaps 402 and flow areas 403 in adjacent layers of first baffles 4 are staggered, so that the gas-water mixture comes into contact with the baffle blocks 401 of each first baffle 4 multiple times during the upward process, causing the water to condense and flow downward along the inner wall of the connecting cylinder 3. Then it flows out of the receiving cavity through the through hole of the second baffle 6 and the second vent of the second connecting pipe 8, thus forming the second separation. After being separated layer by layer by the first baffle 4, the gas-water mixture is discharged through the first vent of the first connecting pipe 2.

[0026] This invention features a simple structure and convenient maintenance. The first separation is achieved through the cooperation of the inner wall of the shell 5, the outer wall of the connecting cylinder 3, and the second baffle 6. The second separation is achieved through the cooperation of the inner wall of the connecting cylinder 3 and each of the first baffles 4. By performing multiple separation operations on the gas-water mixture, the separation efficiency and effect can be improved. Furthermore, the gas separated from the gas-water mixture can be discharged in a closed loop, effectively avoiding the problem of open gas release polluting the cabin environment. The water separated from the gas-water mixture is pressureless and can freely enter and exit the cabin. It is applicable to the separation of gas and water released from air, steam, nitrogen, etc., and has a wider range of applications.

[0027] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
