Description

Technical Field

[0001] The utility model relates to the field of air-conditioning systems, in particular to an air-water separator. Background Art

[0002] In water systems such as heating and air conditioning, gas is present in the pipes. Some of this gas is already present in the pipes, some is dissolved in the water, some is introduced by the water flow in the form of microbubbles, and some is refrigerant leaking from the air conditioning system. Some of these gases are flammable. Once leaked, they can cause explosions, endangering the safety of users. They can also affect the heat exchange efficiency and normal operation of the entire system, increase noise, reduce system efficiency, and corrode and damage equipment such as water pumps, boilers, and heat exchangers. In severe cases, air locks may form, causing the water flow to stop and rendering the system inoperable. Exhaust valves currently used in water systems such as air conditioning and heating can remove gas from the system pipes before they are filled with medium. However, it is difficult to promptly remove microbubbles and dissolved gases in the water. Therefore, these systems require a gas-water separator that can both remove gas from the pipes and the air contained in the flowing water in the pipes in a timely manner to ensure normal system operation. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide a gas-water separator. The invention has a simple structure, prevents water overflow from the drain outlet after startup, has a fast exhaust speed, has a high gas-water separation efficiency, and can effectively capture toxic and flammable gases in water and automatically discharge them.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] The gas-water separator includes a shell, a separation core and an exhaust assembly arranged in the shell; the shell is provided with a lower chamber, an upper chamber located above and connected to the lower chamber, and a water inlet and a water outlet connected to the lower chamber; the separation core is arranged inside the lower chamber, and the exhaust assembly is connected to the upper chamber at the upper end of the shell; it is characterized in that: a floating component linked to the exhaust assembly is also provided in the upper chamber, and a through hole connecting the upper and lower sides thereof is constructed on the floating component; the floating component floats in the upper chamber, and when the floating component is at the upper end of the upper chamber, the exhaust assembly is closed; when the floating component is at the lower end of the upper chamber, the exhaust assembly is open.

[0006] The present invention adopts the above-mentioned technical solution, which relates to a gas-water separator. The housing of the gas-water separator is provided with a separation core and an exhaust assembly. The separation core is provided in a lower chamber of the housing, and the exhaust assembly is provided in an upper chamber of the housing and is in communication with the lower chamber. During use, the water inlet and the water outlet are connected to a liquid pipeline. The liquid in the pipeline flows into the lower chamber through the water inlet. The gas in the liquid adheres to the separation core, and small bubbles continuously gather into large bubbles. The bubbles rise into the upper part of the separation core under the action of buoyancy, and the gas is finally discharged through the exhaust assembly. The separated water flows out of the water outlet of the housing.

[0007] Based on this, this solution incorporates a floating member within the upper chamber. This member rises and falls based on the liquid level within the upper chamber. The floating member is linked to the exhaust assembly, and the height of the floating member controls the opening and closing of the exhaust assembly. This allows the exhaust assembly in the air-water separator to close quickly when the system is filled with water, preventing overflow.

[0008] Therefore, the invention has a simple structure, can prevent water from overflowing from the drain outlet after startup, has a fast exhaust speed, has a high gas-water separation efficiency, and can effectively capture toxic and flammable gases in water and automatically discharge them.

[0009] In a further preferred embodiment, the floating member is constructed in the shape of an inverted cone with a larger diameter at the top and a smaller diameter at the bottom, or a cone with a smaller diameter at the top and a larger diameter at the bottom, or a double-cone with a larger diameter in the middle and smaller diameters at both ends; the largest end of the cone matches the inner diameter of the upper chamber. In this embodiment, the floating member is constructed in a conical or inverted cone shape. The conical design primarily aims to alter the pressure at the bottom or top. The inclined sides reduce pressure, thereby changing the pressure differential between the top and bottom of the floating member, enabling a quicker response.

[0010] In a specific solution, the through hole is constructed as a straight hole connecting the upper end surface and the lower end surface of the floating member. The through hole emphasized here is required to be a straight hole, which facilitates the bubbles captured by the separation core to float through the through hole to the upper chamber above the floating member.

[0011] Preferably, the exhaust assembly includes an exhaust valve and an elastic plug disposed at the inner end of the exhaust valve; the upper end of the floating member is connected to the elastic plug via a connecting rod; the elastic plug is typically a sealing plug, and a spring connected to the sealing plug. When the floating member is at the upper end of the upper chamber, the elastic plug elastically seals the inner end of the exhaust valve. Specifically, the floating member exerts no tension on the elastic plug, and the spring's elastic force allows the sealing plug to block the exhaust valve. When the floating member is at the lower end of the upper chamber, the elastic plug is pulled to open the inner end of the exhaust valve, thereby pulling the spring to deform and open the sealing plug.

[0012] Preferably, the exhaust assembly further includes an exhaust pipe connected to the exhaust valve; the exhaust pipe is provided with a gas sensor for detecting gas. In this embodiment, the gas sensor can be used to detect gas, i.e., gas discharged from the pipe can be detected, thereby issuing a corresponding instruction, such as an alarm. More preferably, the gas sensor is configured to detect flammable and explosive gases, such as methane, thereby issuing an alarm when such flammable and explosive gases are detected.

[0013] Preferably, the water inlet and outlet are arranged on opposite sides of the shell. This allows liquid to flow from the water inlet to the water outlet in multiple directions, fully utilizing the surface of the core unit to improve gas capture efficiency, and preventing the problem of short circuit between the water inlet and the water outlet.

[0014] Preferably, a water inlet connector is connected to the side wall of the housing, and a water inlet is constructed within the connector. The water inlet within the connector is configured to have a flared shape with a diameter gradually increasing from the outside to the inside. A water distribution network is provided within the inlet, and the network has a mesh or porous structure. In this embodiment, the gradually increasing diameter of the water inlet reduces the water flow pressure, making it easier for gas to precipitate.

[0015] Preferably, a drain valve communicating with the lower chamber is provided at the bottom of the shell for draining the internal liquid during maintenance or repair.

[0016] Preferably, a partition is provided in the housing between the upper chamber and the lower chamber, and the partition is evenly distributed with air holes. In this solution, the partition is provided with a porous structure, and the gas will float up after light accumulation. The porous structure is conducive to the uniform passage of the gas into the upper chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1As shown, this embodiment relates to a gas-water separator, comprising a shell 1, and a separation core 2 and an exhaust assembly arranged in the shell 1. A lower chamber 11 is provided inside the shell 1, as well as an upper chamber 12 located above and connected to the lower chamber 11, and a water inlet 13 and a water outlet 14 connected to the lower chamber 11. The separation core 2 is arranged inside the lower chamber 11, and the exhaust assembly is connected to the upper chamber 12 at the upper end of the shell 1. A separation core 2 and an exhaust assembly 5 are provided in the shell 1 of the gas-water separation device, the separation core 2 is provided in the lower chamber 11 in the shell 1, and the exhaust assembly 5 is provided in the upper chamber 12 in the shell 1 and connected to the lower chamber 11. When in use, the water inlet 13 and the water outlet 14 are connected to the liquid pipeline. The liquid in the pipeline flows into the lower chamber 11 through the water inlet 13. The gas in the liquid adheres to the separation core 2, and small bubbles continuously gather into large bubbles. The bubbles rise into the upper part of the separation core 2 under the action of buoyancy, and finally the gas is discharged through the exhaust component 5. The separated water flows out from the water outlet 14 of the shell 1.

[0024] In a specific embodiment, a floating member 6 is provided within the upper chamber 12, interlocked with the exhaust assembly 5. The floating member 6 has a through hole 61 extending from its upper and lower sides. The floating member 6 floats within the upper chamber 12. When the floating member 6 is at the upper end of the upper chamber 12, the exhaust assembly 5 is closed. When the floating member 6 is at the lower end of the upper chamber 12, the exhaust assembly 5 is opened. The floating member 6 rises and falls based on the liquid level within the upper chamber 12, and the floating member 6 is interlocked with the exhaust assembly 5, allowing the exhaust assembly 5 to be opened and closed based on the height of the floating member 6. This allows the exhaust assembly 5 in the gas-water separator to close quickly when the system is filled with water, preventing the exhaust outlet from overflowing. Therefore, this invention has a simple structure, prevents water from overflowing at the drain outlet after startup, provides rapid exhaust, and achieves high primary gas-water separation efficiency, effectively capturing toxic and flammable gases in the water and automatically discharging them.

[0025] In a further preferred embodiment shown in the figure, the floating member 6 is constructed in the shape of an inverted cone with a larger diameter at the top and a smaller diameter at the bottom, or a cone with a smaller diameter at the top and a larger diameter at the bottom, or a double-cone with a larger diameter in the middle and smaller diameters at both ends. The double-cone shape is commonly referred to as a waist drum shape. The largest end of each of these three cone shapes matches the inner diameter of the upper chamber 12. In this embodiment, the floating member 6 is constructed in the shape of a cone, an inverted cone, or a waist drum. The cone design primarily aims to alter the pressure at the bottom or top. The inclined side surfaces reduce pressure, changing the pressure differential between the top and bottom of the floating member 6 and enabling a quick response. The through hole 61 is constructed as a straight hole connecting the top and bottom surfaces of the floating member 6. The straight hole 61 is emphasized here to facilitate the bubbling of bubbles captured by the separation core 2 through the through hole 61 into the upper chamber 12 above the floating member 6.

[0026] like Figure 1 As shown, the exhaust assembly 5 includes an exhaust valve 51 and an elastic plug 52 disposed at the inner end of the exhaust valve 51. The upper end of the floating member 6 is connected to the elastic plug 52 via a connecting rod. The elastic plug 52 is typically a sealing plug and a spring connected to the sealing plug. When the floating member 6 is at the upper end of the upper chamber 12, the elastic plug 52 elastically seals the inner end of the exhaust valve 51. In this case, the floating member 6 does not exert any tension on the elastic plug 52, and the spring force allows the sealing plug to block the exhaust valve 51. When the floating member 6 is at the lower end of the upper chamber 12, the elastic plug 52 is pulled to open the inner end of the exhaust valve 51, thereby pulling the spring to deform and open the sealing plug. Furthermore, the exhaust assembly 5 includes an exhaust pipe connected to the exhaust valve 51. A gas sensor 53 is provided on the exhaust pipe for detecting gas. In this embodiment, the gas sensor 53 can be used to detect gas, that is, to detect gas discharged from the pipe and to issue a corresponding instruction, such as an alarm. A more preferred solution is that the gas sensor 53 is preferably configured to be a sensor capable of detecting flammable and explosive gases, such as methane gas, so that an alarm can be issued when the corresponding flammable and explosive gas is detected.

[0027] In the figure, the water inlet 13 and the water outlet 14 are arranged on opposite sides of the shell 1. In this way, the liquid flows from the water inlet 13 to the water outlet 14 in multiple directions, and the surface of the core unit is fully utilized to improve the gas capture efficiency. And there will be no problem of short circuit from the water inlet 13 to the water outlet 14. A water inlet joint is connected to the side wall of the shell 1, and the water inlet 13 is constructed in the water inlet joint. The water inlet 13 in the water inlet joint is constructed into an expanded shape with a diameter gradually increasing from the outside to the inside, and a water distribution network 15 is provided in the water inlet 13, and the water distribution network 15 is a mesh structure or a porous structure. In this solution, the diameter of the water inlet 13 is gradually enlarged, which reduces the water flow pressure and makes it easier for the gas to precipitate.

[0028] In addition, a drain valve 16 is provided at the bottom of the housing 1 and is in communication with the lower chamber 11 for draining the internal liquid during maintenance or repair.

[0029] In addition, a partition 7 is provided in the housing 1 between the upper chamber 12 and the lower chamber 11, and pores are evenly distributed on the partition 7. In this solution, the partition 7 is provided with a porous structure, and the gas will float up after light accumulation. The porous structure facilitates the uniform passage of gas into the upper chamber.

[0030] Based on the above scheme, the gas-water separator operates as follows: When water contains non-condensable or flammable gases, for safety and practical purposes, the gases must be separated and promptly discharged from the water system. Water enters the device through the water inlet 13 and passes through the water distribution network 15, allowing the water to flow more evenly into the separation core 2. Some of the water passes through the partition 7 and enters the upper chamber. Under the action of buoyancy, the floating member 6 rises, driving the exhaust device to close the exhaust port. Simultaneously, bubbles in the water gather on the core, gradually forming larger bubbles. Under the action of buoyancy, the bubbles rise through the partition 7 and enter the upper chamber. They then enter the gas chamber of the upper chamber through the through hole 61 in the middle of the floating member 6. As the gas accumulates, the pressure causes the floating member 6 to sink, driving the exhaust device to open the exhaust port, thereby discharging the gas through the exhaust port. The separated water flows out of the water outlet 14 on the other side of the housing 1. When the gas passes the gas sensor 53, it issues an alarm signal, indicating that gas is being discharged from the water.

[0031] To sum up, the advantages of this gas-water separator are:

[0032] 1) Simple structure, light weight, can efficiently capture non-condensable gases in water;

[0033] 2) When the air-water separator is filled with water, it can be quickly closed without causing water overflow from the exhaust port;

[0034] 3) The floating member 6 adopts a conical or inverted conical design, which allows the floating member 6 to react quickly;

[0035] 4) The partition 7 has small holes evenly arranged, so that the gas gathered at the bottom can more easily pass into the upper exhaust cavity;

[0036] 5) A gas sensor 53 is added to the exhaust port to increase the alarm function.
