Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a water-air separation device. Background Technology

[0002] In water purifier systems, water-air separation is a crucial technical step. Its purpose is to effectively remove tiny air bubbles, free gases, or vapors entrained in the water flow, ensuring the stability and safety of the equipment's operation. Traditional water-air separation structures often employ simple gravity settling or filter interception methods. However, these traditional structures for separating gas and liquid are relatively complex and costly. Utility Model Content

[0003] Therefore, it is necessary to provide a water-gas separation device to address the problems of complex structures and high costs associated with traditional water purifiers used for separating gas and liquid.

[0004] A water-air separation device includes: a shell assembly with an opening; a cover assembly disposed on the shell assembly and located at the opening; and a vortex structure disposed on the shell assembly and located inside the shell assembly. The shell assembly, the cover assembly, and the vortex structure enclose a vortex space and a flow cavity, both of which are connected to the opening. The shell assembly has an inlet and an outlet, which are sequentially connected. The shell assembly also has a fluid input port connected to the flow cavity, a fluid transport space, and a fluid output port, which are sequentially connected.

[0005] This application discloses a water-gas separation device. A swirling space is formed by a shell assembly, a cover assembly, and a swirling structure. When liquid is delivered from the inlet to the swirling space, a swirling flow is created, and centrifugal force throws the lighter gas into the flow chamber, for example, separating steam and dissolved gases in hot water. When the gas pressure is too high, the gas can enter through the fluid inlet and exit through the fluid outlet, or it can condense into liquid, such as steam. The liquid can enter the flow chamber and exit through the outlet, thus achieving rapid separation of gas and liquid and improving separation efficiency. This design utilizes the swirling principle to separate gas and liquid, ensuring the stability and safety of equipment operation, avoiding or reducing equipment failure caused by excessive pressure, and effectively extending the product's service life. Moreover, the structure is relatively simple, the manufacturing cost is low, and it effectively improves economic benefits.

[0006] In one embodiment, the swirling space includes a first swirling space and a second swirling space, and the inlet, the first swirling space, the second swirling space, and the flow chamber are sequentially connected. By having water flow sequentially through the first and second swirling spaces, two swirling separation processes are formed, which can more fully utilize centrifugal force, resulting in better gas and liquid separation and significantly improving the stability and safety of the equipment operation.

[0007] In one embodiment, the flow chamber includes a first chamber and a second chamber, with the swirling space, the first chamber, the second chamber, and the outlet sequentially connected. The diameter of the second chamber is greater than the width of the first chamber. By increasing the diameter of the second chamber, the volume of the chamber is expanded, reducing pressure and causing steam to condense into liquid, thus utilizing the steam and avoiding or reducing water waste. Furthermore, the reduced water flow rate causes bubbles to naturally rise to the top and aggregate due to density differences, further improving the gas-liquid separation effect.

[0008] In one embodiment, the fluid transport space includes a first fluid channel, a fluid transport chamber, and a second fluid channel, wherein the fluid inlet, the first fluid channel, the fluid transport chamber, the second fluid channel, and the fluid outlet are sequentially connected. Gas flows sequentially through the first fluid channel, the fluid transport chamber, and the second fluid channel, forming a multi-stage flow path. A sufficiently long flow path allows vapor to condense into liquid water, reducing water waste.

[0009] In one embodiment, the housing assembly is provided with a water outlet channel, and the flow chamber, the water outlet channel, and the water outlet are sequentially connected. The water outlet channel provides a clear flow path for the liquid after separation from the gas, ensuring that the liquid discharged from the flow chamber can be quickly and orderly guided to the water outlet, avoiding turbulence.

[0010] In one embodiment, the height of the fluid inlet relative to the horizontal plane is greater than or equal to the height of the highest point of the water inlet relative to the horizontal plane. By making the height of the fluid inlet greater than the height of the water inlet, the risk of liquid entering from the fluid inlet and blocking the gas delivery path, leading to excessive gas pressure in the flow chamber, can be effectively avoided or reduced, thus improving the stability and safety of the equipment.

[0011] In one embodiment, the fluid outlet is arranged around the water outlet. This arrangement allows for a more compact structure.

[0012] In one embodiment, the swirling structure includes a first swirling element and a second swirling element, both of which are disposed on the housing assembly. The housing assembly, the cover assembly, and the first swirling element enclose a first swirling space, and the housing assembly, the cover assembly, the first swirling element, and the second swirling element enclose a second swirling space. The inlet, the first swirling space, the second swirling space, and the flow cavity are sequentially connected. By using the first and second swirling elements to form the first and second swirling spaces, centrifugal force can be used to separate the liquid and gas at least twice, improving the separation effect and effectively increasing the gas removal rate and liquid purity.

[0013] In one embodiment, the cross-section of the first swirling element is bent, arc-shaped, or meandering. By using the bent, arc-shaped, or meandering cross-section of the first swirling element, the fluid can be guided to form a swirling flow, thereby using centrifugal force to separate the gas and liquid. This design makes the gas-liquid separation method simple and convenient, and the structure used for separating gas and liquid is relatively simple and low-cost.

[0014] In one embodiment, the cross-section of the second swirling element is bent, arc-shaped, or meandering. The bent, arc-shaped, or meandering cross-section of the second swirling element guides the fluid to form a swirling flow, thereby utilizing centrifugal force to separate the gas and liquid.

[0015] In one embodiment, there are multiple first swirling elements, all disposed on the housing assembly and located inside the housing assembly. A gap is formed between the multiple first swirling elements, and the first swirling space, the gap, and the second swirling space are sequentially connected. The arrangement of multiple first swirling elements forms multiple first swirling spaces, enabling liquids input through multiple inlets to generate swirling currents, thus achieving gas-liquid separation. The gap between the multiple first swirling elements ensures that liquids within the first swirling spaces can be transported to the second swirling space for further swirling, thereby further enhancing gas-liquid separation.

[0016] In one embodiment, the first swirling element is a hydrophobic baffle or a hydrophobic filter. By providing multiple layers of hydrophobic baffles or filters, microbubbles are further blocked, while the liquid can flow through the gaps between the multiple hydrophobic baffles or filters, effectively achieving gas and liquid separation. The hydrophobic baffles or filters can effectively prevent bubble adhesion.

[0017] In one embodiment, the second swirling element is a hydrophobic baffle or a hydrophobic filter. By using a hydrophobic baffle or a hydrophobic filter as the second swirling element, gas can be transported from above the second swirling element to the top, while liquid continues to flow from the space between the second and first swirling elements, forming a swirling flow and achieving gas and liquid separation.

[0018] In one embodiment, the first swirling element includes a first swirling section and a second swirling section, both of which are disposed on the housing assembly and connected. The second swirling section is inclined relative to the first swirling section. The housing assembly, the cover assembly, the first swirling section, and the second swirling section enclose and form the first swirling space. By inclining the second swirling section relative to the first swirling section, the liquid forms a swirling flow under the guidance of the first swirling element, achieving gas and liquid separation. This gas and liquid separation structure is simple, easy to manufacture, and can effectively reduce production costs.

[0019] In one embodiment, the housing assembly is provided with a water inlet channel, the water inlet, the water inlet channel, and the first vortex space are sequentially connected, and the water inlet channel extends toward the first vortex section. Because the water inlet channel extends toward the first vortex section, the liquid initially flows toward the first vortex section upon entry and, guided by the first vortex section, flows toward the second vortex section. The second vortex section is inclined relative to the first vortex section, thus forming a vortex and achieving separation of gas and liquid.

[0020] In one embodiment, the water inlet channel extends tangentially to the spatial wall of the first vortex space. By extending the water inlet channel tangentially to the spatial wall of the first vortex space and towards the first vortex section, a longer vortex path is provided, resulting in better centrifugal separation of gas and liquid after the liquid enters.

[0021] In one embodiment, a swirling column is further included, which is disposed on the housing assembly and located inside the housing assembly. The housing assembly, the cover assembly, the first swirling element, and the swirling column enclose the first swirling space. With the swirling column positioned and the water inlet channel located on its side, liquid input through the water inlet channel can enhance the swirling effect under the action of the swirling column, further improving the gas-liquid separation effect.

[0022] In one embodiment, the second swirling element includes a support block, a first swirling block, and a second swirling block. The support block, the first swirling block, and the second swirling block are all disposed on the housing assembly and located inside the housing assembly. Both the first swirling block and the second swirling block are connected to the support block. The arrangement of the support block, the first swirling block, and the second swirling block creates multiple swirling spaces between the support block and the first swirling element, achieving liquid diversion, resulting in high liquid transport efficiency and better separation of liquid and gas.

[0023] In one embodiment, the cover assembly is provided with a vent hole communicating with the flow chamber. It also includes a valve assembly disposed on the cover assembly. The valve assembly can engage or disengage with the vent hole. When engaged, the vent hole is blocked; when disengaged, the vent hole is open to the outside. The valve assembly can manually or automatically control the opening and closing of the vent hole as needed, enabling venting when the air pressure is too high, thus ensuring the stability and safety of the equipment.

[0024] In one embodiment, a first flange is formed on the cover assembly, surrounding the opening, and a second flange is formed on the housing assembly, with the first flange abutting against the second flange. By abutting the first flange of the cover assembly against the second flange of the housing assembly, the contact area between the cover assembly and the housing assembly is increased, resulting in a more secure fit. For example, if the cover assembly and the housing assembly are welded, the presence of the first and second flanges increases the welding contact area.

[0025] In one embodiment, the housing assembly includes a first housing and a second housing. A cover assembly is disposed on the first housing. The first housing has a water inlet, a water outlet, a fluid input port, and an opening. The first housing, the cover assembly, and the vortex structure enclose the vortex space and the flow cavity. The second housing is disposed on the first housing, and the second housing and the first housing enclose the fluid transport space. The second housing has the fluid output port. The arrangement of the first and second housings enables the transport of water and air, achieving water-air separation and the integration of water and air transport functions, resulting in a more compact overall structure.

[0026] In one embodiment, the first housing includes a housing body, a water inlet pipe, and a partition. The cover assembly is disposed on the housing body, the housing body has the opening and the water outlet, the water inlet pipe is disposed on the housing body and has the water inlet, the partition is disposed on the housing body and located inside the housing body, the partition has the fluid inlet or the partition and the housing body enclose the fluid inlet, and the housing body, the cover assembly, the partition, and the swirling structure enclose the flow cavity. The housing body and the partition effectively separate the water flow path and the air flow path, achieving water-air separation and transport.

[0027] In one embodiment, the second housing includes a support portion, a rib portion, and an output portion. The support portion is disposed on the first housing, and the rib portion and the output portion are both disposed on the support portion and located on opposite sides of the support portion. The first housing has a first fluid channel. The support portion, the rib portion, and the first housing together form a fluid delivery cavity. The output portion and the first housing together form a second fluid channel. The output portion has a fluid output port. The fluid input port, the first fluid channel, the fluid delivery cavity, the second fluid channel, and the fluid output port are sequentially connected. Stable airflow delivery is achieved through the arrangement of the support plate, the rib portion, and the output portion. Attached Figure Description

[0047] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0049] like Figure 1-5 As shown, this embodiment discloses a water-air separation device, including: a shell assembly 1, the shell assembly 1 having an opening 101; a cover assembly 2, the cover assembly 2 being disposed on the shell assembly 1 and located at the opening 101; and a vortex structure 3, the vortex structure 3 being disposed on the shell assembly 1 and located inside the shell assembly 1. The shell assembly 1, the cover assembly 2, and the vortex structure 3 enclose a vortex space 103 and a flow cavity 104. The vortex space 103 and the... All flow passages 104 are connected to the openings 101; the housing assembly 1 is provided with an inlet 102 and an outlet 105, the inlet 102, the swirling space 103, the flow passages 104 and the outlet 105 are connected in sequence, the housing assembly 1 is provided with a fluid inlet 106 connected to the flow passages 104, the housing assembly 1 is provided with a fluid transport space 107 and a fluid outlet 108, the fluid inlet 106, the fluid transport space 107 and the fluid outlet 108 are connected in sequence.

[0050] This application discloses a water-gas separation device. A swirling space 103 is formed by a shell assembly 1, a cover assembly 2, and a swirling structure 3. When liquid is transported from the inlet 102 to the swirling space 103, a swirling flow is formed. Centrifugal force propels the lighter gas towards the flow chamber 104, for example, separating steam and dissolved gases in hot water. When the pressure is too high, gas can enter through the fluid inlet 106 and exit through the fluid outlet 108, or it can condense into liquid, such as steam. The steam adheres to the shell surface and remains for 0.5-1 seconds before breaking, allowing the liquid to enter the flow chamber 104 and exit through the outlet 105, thus achieving rapid separation of gas and liquid and improving separation efficiency. This design utilizes the swirling principle to separate gas and liquid, ensuring the stability and safety of equipment operation, avoiding or reducing equipment failure caused by excessive pressure, and effectively extending product lifespan. Furthermore, the structure is relatively simple, with low manufacturing costs, effectively improving economic benefits. The volume of the water-gas separation structure is matched to the water volume processed, generally requiring sufficient residence time, such as 0.5-2 seconds. Food-grade PP can be selected as the material, which is pressure-resistant and corrosion-resistant. It can withstand high-temperature and high-pressure steam, preventing structural deformation or cracking. It also adapts to thermal expansion and contraction, preventing seal failure. The water-gas separation structure is tilted at 5-10 degrees during installation to assist gas accumulation. The top of the shell (gas accumulation area) can be made with a higher roughness, such as Ra 6.3-12.5μm, such as sandblasting, to accelerate bubble bursting and accumulation; the middle of the shell can be made with moderate roughness, such as Ra 3.2-6.3μm, to enhance turbulence but avoid excessive pressure loss; the bottom of the shell can be made with a lower roughness, such as Ra 1.6-3.2μm, to stabilize water flow and reduce eddies.

[0051] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the vortex space 103 includes a first vortex space 1031 and a second vortex space 1032, and the inlet 102, the first vortex space 1031, the second vortex space 1032, and the flow chamber 104 are sequentially connected. By having water flow sequentially through the first vortex space 1031 and the second vortex space 1032, two vortex separation processes are formed, which can more fully utilize the centrifugal force, resulting in better gas and liquid separation and significantly improving the stability and safety of equipment operation.

[0052] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the flow cavity 104 includes a first cavity 1041 and a second cavity 1042, the swirling space 103, the first cavity 1041, the second cavity 1042, and the outlet 105 are sequentially connected, and the diameter of the second cavity 1042 is greater than the width of the first cavity 1041. By making the diameter of the second cavity 1042 greater than the width of the first cavity 1041, the volume of the cavity is increased, the pressure is reduced, and the steam condenses into liquid, realizing the utilization of steam and avoiding or reducing the waste of water resources. Moreover, the water flow rate is reduced, and the bubbles naturally rise to the top and gather due to the density difference, which can further improve the separation effect of gas and liquid.

[0053] like Figure 3 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fluid transport space 107 includes a first fluid channel 1071, a fluid transport chamber 1072, and a second fluid channel 1073; the fluid inlet 106, the first fluid channel 1071, the fluid transport chamber 1072, the second fluid channel 1073, and the fluid outlet 108 are sequentially connected. Gas sequentially passes through the first fluid channel 1071, the fluid transport chamber 1072, and the second fluid channel 1073 to form a multi-stage flow path. A sufficiently long flow path allows steam to condense into liquid water, reducing water waste.

[0054] like Figure 3 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a water outlet channel, and the flow chamber 104, the water outlet channel, and the water outlet 105 are sequentially connected. The water outlet channel provides a clear flow path for the liquid after separation from the gas, ensuring that the liquid discharged from the flow chamber 104 can be quickly and orderly guided to the water outlet 105, avoiding turbulence. The water outlet channel is cylindrical, which can increase the flow rate by more than 80%.

[0055] like Figure 5-6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the height of the fluid inlet 106 relative to the horizontal plane is greater than or equal to the height of the highest point of the water inlet 102 relative to the horizontal plane. By making the height of the fluid inlet 106 greater than the height of the water inlet 102, the risk of liquid entering from the fluid inlet 106 and blocking the gas delivery path, resulting in excessive gas pressure in the flow chamber 104, can be effectively avoided or reduced, thus improving the stability and safety of the equipment.

[0056] like Figure 3 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the fluid outlet 108 is arranged around the water outlet 105. By arranging the fluid outlet 108 around the water outlet 105, the structure becomes more compact.

[0057] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the swirling structure 3 includes a first swirling element 31 and a second swirling element 32, both of which are disposed on the housing assembly 1. The housing assembly 1, the cover assembly 2, and the first swirling element 31 enclose a first swirling space 1031, and the housing assembly 1, the cover assembly 2, the first swirling element 31, and the second swirling element 32 enclose a second swirling space 1032. The inlet 102, the first swirling space 1031, the second swirling space 1032, and the flow cavity 104 are sequentially connected. By setting the first swirling element 31 and the second swirling element 32 to form the first swirling space 1031 and the second swirling space 1032, centrifugal force can be used to separate the liquid and gas at least twice, improving the separation effect and effectively increasing the gas removal rate and liquid purity.

[0058] like Figure 6-9As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the first swirling element 31 is bent, arc-shaped, or meandering. By having the cross-section of the first swirling element 31 bent, arc-shaped, or meandering, the fluid can be guided to form a swirling flow, thereby using centrifugal force to separate the gas and liquid. This design makes the gas and liquid separation method simple and convenient, and the structure used for separating gas and liquid is relatively simple and low-cost.

[0059] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the second swirling element 32 is bent, arc-shaped, or meandering. By having the cross-section of the second swirling element 32 bent, arc-shaped, or meandering, the fluid can be guided to form a swirling flow, thereby utilizing centrifugal force to separate the gas and liquid.

[0060] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of the first swirling elements 31 is multiple, all of which are disposed on the housing assembly 1 and located inside the housing assembly 1. A gap 301 is formed between the multiple first swirling elements 31, and the first swirling space 1031, the gap 301, and the second swirling space 1032 are sequentially connected. The multiple first swirling elements 31 form multiple first swirling spaces 1031, enabling the liquid input into the corresponding multiple inlets 102 to generate swirling currents, thereby achieving gas-liquid separation. The gaps 301 between the multiple first swirling elements 31 ensure that the liquid in the first swirling space 1031 can be transported to the second swirling space 1032 for re-swirling, further enhancing gas-liquid separation.

[0061] In addition to the features of the above embodiments, this embodiment further specifies that the first swirling element 31 is a hydrophobic baffle or a hydrophobic filter. By providing multiple layers of hydrophobic baffles or hydrophobic filters, microbubbles are further blocked, while the liquid can flow through the gaps 301 between the multiple hydrophobic baffles or hydrophobic filters, effectively achieving gas and liquid separation. The hydrophobic baffles or hydrophobic filters can effectively prevent bubble adhesion.

[0062] In addition to the features of the above embodiments, this embodiment further specifies that the second swirling element 32 is a hydrophobic baffle or a hydrophobic filter. Because the second swirling element 32 is a hydrophobic baffle or a hydrophobic filter, gas can be transported from above the second swirling element 32 to the top, while liquid continues to flow from the space between the second swirling element 32 and the first swirling element 31 to form a swirling flow, thus achieving gas and liquid separation.

[0063] like Figure 6-9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first swirling element 31 includes a first swirling section 311 and a second swirling section 312, both the first swirling section 311 and the second swirling section 312 are disposed on the housing assembly 1 and connected, the second swirling section 312 is inclined relative to the first swirling section 311, and the housing assembly 1, the cover assembly 2, the first swirling section 311 and the second swirling section 312 enclose and form the first swirling space 1031. By inclining the second swirling section 312 relative to the first swirling section 311, the liquid forms a swirling flow under the guidance of the first swirling element 31, achieving gas and liquid separation. This gas and liquid separation structure is simple, easy to manufacture, and can effectively reduce production costs.

[0064] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a water inlet channel 109, the water inlet 102, the water inlet channel 109 and the first vortex space 1031 are sequentially connected, and the water inlet channel 109 extends toward the first vortex section 311. Because the water inlet channel 109 extends toward the first vortex section 311, the liquid first flows toward the first vortex section 311 upon entering and then flows toward the second vortex section 312 under the guidance of the first vortex section 311. The second vortex section 312 is inclined relative to the first vortex section 311, thus forming a vortex and achieving gas and liquid separation. The flow velocity of the water inlet channel 109 needs to balance separation efficiency and pressure loss, and is typically designed to be 0.5-1.5 m / s.

[0065] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the extending direction of the water inlet channel 109 is tangent to the spatial wall of the first vortex space 1031. By extending the water inlet channel 109 tangent to the spatial wall of the first vortex space 1031 and extending the water inlet channel 109 toward the first vortex section 311, a longer vortex path is provided, thereby improving the centrifugal separation effect of gas and liquid after the liquid enters.

[0066] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further includes a swirling column 33, which is disposed on the housing assembly 1 and located inside the housing assembly 1. The housing assembly 1, the cover assembly 2, the first swirling element 31, and the swirling column 33 enclose and form the first swirling space 1031. With the swirling column 33 disposed and the water inlet channel 109 located on the side of the swirling column 33, the liquid input from the water inlet channel 109 can enhance the swirling effect under the action of the swirling column 33, further improving the separation effect of gas and liquid.

[0067] like Figure 6-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second swirling element 32 includes a support block 321, a first swirling block 322, and a second swirling block 323. The support block 321, the first swirling block 322, and the second swirling block 323 are all disposed on the housing assembly 1 and are all located inside the housing assembly 1. The first swirling block 322 and the second swirling block 323 are both connected to the support block 321. The arrangement of the support block 321, the first swirling block 322, and the second swirling block 323 allows for the formation of multiple swirling spaces 103 between the support block 321 and the first swirling element 31, achieving liquid diversion, thereby resulting in high liquid transport efficiency and better separation of liquid and gas.

[0068] like Figure 14 and Figure 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the cover assembly 2 is provided with an exhaust port 201, the exhaust port 201 is connected to the flow chamber 104, and also includes a valve body assembly 4, the valve body assembly 4 is disposed on the cover assembly 2, the valve body assembly 4 can cooperate with or separate from the exhaust port 201. When the valve body assembly 4 is cooperated with the exhaust port 201, the exhaust port 201 is blocked; when the valve body assembly 4 is separated from the exhaust port 201, the exhaust port 201 is connected to the outside.
