Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioning system field especially relates to an air conditioning system and air water separation device thereof. BACKGROUND

[0002] In the water system such as heating or air conditioning, there are gases in the pipeline, some of which are originally in the pipeline, some are dissolved in water, some are brought into the water system in the form of micro-bubbles by water flow, and some are refrigerants leaked from the air conditioning system into the water system. Some of these gases are flammable, which may cause explosion and endanger the safety of users once leaked. It also affects the heat exchange effect of the whole system and the normal operation of the system, increases noise, reduces system efficiency, corrodes and damages water pumps, boilers, heat exchangers and other equipment, and in severe cases may form air lock, stop water flow and cause the system to fail to operate. The air exhaust valve used in the water system such as air conditioning and heating can remove the gas existing in the pipeline before the pipeline is filled with medium, but it is difficult to remove the micro-bubbles in the water and the gas dissolved in the water in time. Therefore, an air-water separator is needed in these systems, which can not only remove the gas in the pipeline, but also remove the air contained in the water in the pipeline in time, to ensure the normal operation of the system.

[0003] The prior art such as the Chinese utility model patent with the announcement number "CN221254018U" relates to an air conditioning system and air water separation device thereof.

[0004] This scheme has the following two problems:

[0005] Firstly, the separation core structure adopted by this scheme is relatively complex, and the cost is high;

[0006] Secondly, the water outlet of this scheme is further arranged below the annular partition plate, specifically below the separation core, so that the liquid flowing from the water inlet must pass through the separation core inside the annular partition plate to flow to the water outlet. However, this will cause short circuit of the water inlet and the water outlet, that is, the part of the separation core farthest from the nearest path of the water inlet and the water outlet cannot play a role. SUMMARY

[0007] In order to solve the above problems, the utility model discloses a gas water separation device, which can increase the air adhesion area of the separation core, guide the liquid flow direction and fully utilize the adhesion surface of the separation core.

[0008] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

Furthermore, a gap is left between the outer annular separation plates of the core units and the inner wall of the separation cavity of the shell, so that the liquid flows from the gap between the separation core and the inner wall of the separation cavity, thereby making full use of the outer surface of the outer annular separation plate to capture bubbles.

[0018] In specific embodiments, the water inlet and the water outlet are arranged on opposite sides of the shell. In this way, the liquid flows from the water inlet to the water outlet in multiple directions, making full use of the surface of the core units to improve the gas capturing efficiency, and avoiding the short circuit problem from the water inlet to the water outlet as described in the background art.

[0032] Example 1:

[0033] As shown in Figure 1 and 2 shown, the embodiment relates to a gas-water separation device, comprising a shell 20, and a separation core 4 and an exhaust assembly 3 arranged in the shell 20. The shell 20 is internally provided with a separation cavity 21, and a water inlet 22 and a water outlet 23 connected with the separation cavity 21. The separation core 4 is arranged in the separation cavity 21, and the exhaust assembly 3 is connected to the upper end of the shell 20 and communicated with the separation cavity 21. The shell of the gas-water separation device is provided with the separation core 4 and the exhaust assembly 3, the separation core 4 is arranged in the separation cavity in the shell, and the exhaust assembly 3 is connected to the upper end of the shell and communicated with the separation cavity 21. In use, the water inlet 22 and the water outlet 23 are connected to the liquid pipeline, and the liquid in the pipeline flows into the separation cavity 21 through the water inlet 22, the gas in the liquid adheres to the separation core 4, small bubbles are continuously collected into large bubbles, the bubbles rise to the upper part of the separation core 4 under the action of buoyancy, and finally the gas is discharged through the exhaust assembly 3, and the separated water flows out from the water outlet 23 of the shell.

[0034] As shown in Figure 1 , the exhaust assembly 3 comprises an exhaust valve 31 and an exhaust pipeline 32 connected to the exhaust valve 31. The exhaust pipeline 32 is provided with a gas-sensitive sensor 33 for detecting gas. In this scheme, the gas-sensitive sensor can be used to detect gas, that is, the exhaust gas in the pipeline can be detected, and then corresponding instructions such as alarms can be issued. A better scheme is that the gas-sensitive sensor is preferably a sensor capable of detecting flammable and explosive gas such as methane gas. Thus, when the corresponding flammable and explosive gas is detected, an alarm can be issued.

[0035] As shown in Figure 2 , the separation core 4 comprises a main shaft 41 fixed at the center of the separation cavity 21, and a plurality of core units 42 uniformly arranged along the circumference of the center of the separation cavity 21. The inner ends of the plurality of core units 42 are fixed to the main shaft 41. In this scheme, the inner ends of the plurality of core units 42 can be fixed to the main shaft 41, thereby facilitating the fixation and circumferential regular arrangement of the core units 42. In a specific embodiment, each core unit 42 comprises at least an outer annular separation plate 421 and an inner annular separation plate 422 arranged concentrically, and the outer annular separation plate 421 and the inner annular separation plate 422 are both mesh plates. In some other schemes, at least one middle annular separation plate can be arranged between the outer annular separation plate 421 and the inner annular separation plate 422, and the middle annular separation plate is also a mesh plate, which can further improve the gas supplement efficiency.

[0036] The difference between the present solution and the prior art is that the separation core 4 in the present solution comprises a plurality of core units 42 arranged in a regular circumferential direction, and each core unit 42 comprises at least an outer annular separation plate 421 and an inner annular separation plate 422 arranged concentrically. Based on the above solution, after the liquid flows into the separation cavity 21 from the water inlet 22, part of the liquid can flow along the periphery of the plurality of core units 42, so that the gas in the part of the liquid adheres to the outer sidewall of the outer annular separation plate 421. In addition, part of the liquid can flow through the holes of the outer annular separation plate 421 and the inner annular separation plate 422, so that the gas in the part of the liquid adheres to the inner sidewall of the outer annular separation plate 421 and the inner and outer sidewalls of the inner annular separation plate 422. In summary, the above solution not only increases the air adhesion area on the separation core 4, but also guides the liquid flow direction, and fully utilizes the adhesion surface of the separation core 4. In this way, it is easier to collect the gas in the liquid and improve the gas capture efficiency.

[0037] In a further solution, the outer annular separation plates 421 of the plurality of core units 42 are adjacent or tangent to each other, and a gap 420 is left between the outer annular separation plate 421 of the core unit 42 and the inner wall of the separation cavity 21 of the shell 20. In the present solution, the plurality of core units 42 are required to be as close as possible to each other, so that the liquid passing through the separation core 4 flows as close as possible to the surface of the outer annular separation plate 421, facilitating gas replenishment. Furthermore, the gap 420 is left between the outer annular separation plate 421 of the core unit 42 and the inner wall of the separation cavity 21 of the shell 20, so that the liquid flows from the gap 420 between the separation core 4 and the inner wall of the separation cavity 21, thereby fully utilizing the outer surface of the outer annular separation plate 421 to capture bubbles.

[0038] In a specific embodiment, the outer annular separation plate 421 and the inner annular separation plate 422 are connected by a plurality of radially distributed connecting ribs 423, the inner end of the connecting rib 423 is connected to the inner annular separation plate 422, and the outer end is connected to the outer annular separation plate 421. In the present solution, the plurality of radially distributed connecting ribs 423 are used to connect the outer annular separation plate 421 and the inner annular separation plate 422, so that the outer annular separation plate 421 and the inner annular separation plate 422 are arranged concentrically. In addition, in a preferred solution, the density of the through holes on the inner annular separation plate 422 is greater than that on the outer annular separation plate 421. In the present solution, large bubbles are less likely to pass through the inner annular separation plate 422 and adhere to the outer wall of the inner annular separation plate 422, and the inner wall of the inner annular separation plate 422 can be used for further adhesion of small bubbles, so that microbubbles can be collected into large bubbles.

[0039] As Figure 1 and 2As shown, the water inlet 22 and the water outlet 23 are arranged on opposite sides of the shell 20. In this way, the liquid flows from the water inlet 22 to the water outlet 23 in multiple directions, and the surface of the core unit 42 is fully utilized, improving the gas capture efficiency. Moreover, the problem of short circuiting from the water inlet 22 to the water outlet 23 as described in the background art does not occur. The side wall of the shell 20 is connected with a water inlet connector 220, and the water inlet 22 is formed in the water inlet connector 220. The water inlet 22 in the water inlet connector 220 is formed in a flared shape with a gradually increasing diameter from the outside to the inside, and the water inlet 22 is provided with a water equalizing net 24 in a mesh structure or a porous structure. In this scheme, the diameter of the water inlet 22 gradually increases, reducing the water flow pressure, and the gas is more easily separated out.

[0040] In summary, the characteristics and advantages of the above-mentioned new steam-water separator are as follows:

[0041] 1) The structure is simple, and the non-condensable gas in the water can be efficiently captured.

[0042] 2) The diameter of the water inlet 22 gradually increases, reducing the water flow pressure, and the gas is more easily separated out.

[0043] 3) The concentric core makes it easier for microbubbles to gather into large bubbles.

[0044] 4) The exhaust port is provided with a gas sensitive sensor to increase the alarm function

[0045] 5) Multiple circular filter cartridges are uniformly arranged in a circular shape to form a curved flow channel, allowing the water flow to change direction multiple times, and the bubbles are more easily accumulated on the filter cartridges due to inertia.

[0046] 6) The circular filter cartridge allows the water flow to change from linear motion to circular motion when entering, generating centrifugal force to separate small bubbles, which are more easily captured by the filter cartridge.

[0047] 7) Multiple concentric circles are designed with channels between them to form gas-water separation and reduce the interference of water flow on the accumulation and upward movement of bubbles.

[0048] 8) Multiple circular filter cartridges have smaller volume under the same surface area
