Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam generation technology, and in particular to a deoxygenation device and a heat pump air conditioner. Background Technology
[0002] A flooded evaporator is a widely used heat exchange device in refrigeration systems. It primarily evaporates liquid refrigerant into a gas while absorbing heat from the medium being cooled, thus achieving refrigeration or temperature reduction. Its working principle involves filling the surface of the heat exchange tubes or fins of the evaporator with liquid refrigerant, relying on natural or forced convection for heat exchange. It offers advantages such as high heat exchange efficiency, simple structure, and low cost.
[0003] Horizontal tube evaporators, which are filled with liquid, can be used as steam generators. The shell-side space outside the heat exchange tubes contains boiling water, while the inside of the tubes contains other heat transfer fluids that heat the water to produce high-temperature steam. During the heat exchange process in the steam generator, dissolved oxygen in the water precipitates and corrodes the shell-side structure of the heat exchanger (especially at welded joints), affecting the corrosion resistance and safety of the steam generator. Therefore, separating oxygen and water is crucial to prevent corrosion caused by oxygen in the steam.
[0004] With the continuous updating and iteration of various technologies, the technology for separating dissolved oxygen in water is also constantly developing. Existing separation technologies are mainly divided into chemical methods and physical methods. Physical methods include distillation and membrane separation, while chemical methods include using redox reactions to remove oxygen from water. However, the above methods are not widely used in steam generators. Generally, the water needs to be deoxygenated first, which cannot efficiently utilize the high-temperature steam in existing steam generators to promote the rapid precipitation of dissolved oxygen, resulting in high costs and waste. Utility Model Content
[0005] This invention provides an oxygen removal device and a heat pump air conditioner to solve the problem in the prior art that the high-temperature water vapor in the existing steam generation chamber cannot be effectively used to promote the rapid release of dissolved oxygen.
[0006] The technical solution of this utility model is a deoxygenation device, which is installed in the steam generation chamber of the target equipment. The deoxygenation device includes:
[0007] Main structure;
[0008] Multiple liquid inlets are provided on the main structure;
[0009] Multiple pipe structures are installed within the main structure, with their inlet ends all connected to the corresponding inlet ports, and their outlet ends all penetrating the remaining side walls of the main structure where no inlet port is provided.
[0010] A discrete structure is provided at the liquid outlet end of the pipeline structure, which is used to increase the degree of dispersion and breakup of the liquid to be deoxygenated passing through.
[0011] Furthermore, the discrete structure includes a rolling groove and a rolling element;
[0012] Each of the pipe structures has a circumferentially circumferentially provided rolling groove at the outlet end, and the rolling groove is connected to the pipe structure; multiple rolling elements are embedded in the rolling groove, and each rolling element can rotate radially and / or roll circumferentially relative to the rolling groove.
[0013] Furthermore, the discrete structure includes a variable cross-section flow channel and a support member;
[0014] Each of the pipe structures has multiple variable cross-section flow channels arrayed at its outlet end. Each variable cross-section flow channel is connected to the corresponding pipe structure, and the outer edge of the variable cross-section flow channel is connected to the inner wall of the corresponding pipe structure through the support member.
[0015] Furthermore, the discrete structure includes a rolling groove, a rolling element, a variable cross-section flow channel, and a support element;
[0016] Each of the aforementioned pipe structures has a circumferentially provided rolling groove at its outlet end. Multiple rolling elements are embedded in the rolling groove, and each rolling element can rotate radially and / or roll circumferentially relative to the rolling groove.
[0017] Multiple variable cross-section flow channels are arrayed on the inner or outer side of the rolling groove. The outer edge of the variable cross-section flow channel is connected to the inner wall of the corresponding pipe structure through the support member. Both the variable cross-section flow channel and the rolling groove are connected to the pipe structure.
[0018] Furthermore, the radial cross-section of the variable cross-section flow channel gradually decreases along the flow direction of the liquid to be deoxygenated.
[0019] Furthermore, the variable cross-section flow channel is provided with multiple layers of staggered serrated baffles at its end along the flow direction.
[0020] Furthermore, the main structure is a rotationally symmetric body, and the outer wall of the main structure has inwardly recessed liquid inlet areas on both sides along the radial direction, and multiple liquid inlets are arrayed in the liquid inlet areas.
[0021] Furthermore, a partition is provided around the equatorial plane of the main structure, and multiple sets of discrete structure groups are provided on both sides of the partition along the circumference of the equatorial plane of the main structure. Each set of discrete structure groups has multiple discrete structures arranged radially.
[0022] The equatorial plane is perpendicular to the line connecting the centers of the oppositely positioned liquid inlet areas.
[0023] This utility model also proposes a heat pump air conditioner, including a steam generator with a steam generating chamber, wherein the steam generating chamber is equipped with the deoxygenation device as described above.
[0024] Furthermore, the top wall of the steam generating chamber is provided with a water inlet, which is connected to the liquid inlet on the main structure through a water supply pipe, thereby suspending the deoxygenation device inside the steam generating chamber.
[0025] Compared with the prior art, the present invention has at least the following beneficial effects:
[0026] This invention utilizes a pipe structure to break up and disperse the liquid to be deoxygenated before it flows into the steam generation chamber. This increases the dispersion range of water within the steam generation chamber, thereby increasing the contact area between the water flowing out of the deoxygenator and the high-temperature steam in the steam generation chamber. This allows the water flowing out of the deoxygenator to be heated and deoxygenated more thoroughly, enabling the water to be quickly heated to saturation by the high-temperature steam and fully release oxygen. This increases the rate of dissolved oxygen release from the water, thereby reducing the oxygen content in the water. Attached Figure Description

[0052] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.
[0053] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0054] In some embodiments, such as Figure 1 and Figure 8 As shown, this utility model proposes a deoxygenation device installed in the steam generating chamber 1 of the target equipment, the deoxygenation device comprising:
[0055] Main structure 10;
[0056] Multiple liquid inlets 101 are provided on the main structure 10;
[0057] Multiple pipe structures 20 are installed in the main structure 10, and their liquid inlet ends are all connected to the corresponding liquid inlet 101, while their liquid outlet ends all penetrate vertically through the remaining side walls of the main structure 10 where the liquid inlet 101 is not provided.
[0058] The discrete structure 30 is disposed at the liquid outlet end of the pipeline structure 20. The discrete structure 30 is used to increase the degree of dispersion and breakage of the liquid to be deoxygenated passing through.
[0059] It should be noted that the target equipment proposed in this embodiment is preferably a steam generator, and the liquid to be deoxygenated is preferably water. The shape of the pipe structure 20 is preferably L-shaped, S-shaped, or other shapes that facilitate flow, and is not limited here; however, this embodiment uses an L-shaped pipe as an example, and the same applies throughout.
[0060] The inlet 101 is used to connect to the water supply pipe 3 of the target equipment so that water can flow through the inlet 101 to the corresponding pipe structure 20. When the water in the pipe structure 20 passes through the discrete structure 30, the discrete structure 30 will break and disperse the water before it flows out into the steam generating chamber 1. This increases the dispersion range of water in the steam generating chamber 1, thereby increasing the contact area between the water flowing out of the deoxygenator and the high-temperature steam in the steam generating chamber 1. This makes the water flowing out of the deoxygenator more thoroughly deoxygenated, so that the water can be quickly heated to saturation by the high-temperature steam and oxygen can be fully released. This increases the rate of dissolved oxygen release in the water and reduces the oxygen content in the water.
[0061] Furthermore, the oxygen released is discharged from the exhaust port 4 at the top of the target equipment along with the rising high-temperature steam, thereby preventing the released oxygen from re-integrating into the deoxygenated water, preventing dissolved oxygen from oxidizing and corroding the metal materials inside the target equipment, avoiding rust from falling off and adhering to the heat exchange tubes 5 of the target equipment, ensuring heat exchange efficiency, reducing the cost of maintenance and replacement of the target equipment, and extending the service life of the target equipment; the deoxygenated water is stored at the bottom of the steam generation chamber 1 so that the target equipment can continuously generate high-temperature steam in subsequent steps.
[0062] Compared to solutions that place the deoxygenation device outside the target equipment, this embodiment integrates the deoxygenation device into the steam generation chamber 1 of the target equipment, which greatly improves space utilization and eliminates the need for additional external space. Furthermore, the high temperature of the steam itself allows it to be used directly as a heat source for the water flowing out of the deoxygenation device, eliminating the need to provide an additional heat source for the device. The thermal deoxygenation method is less prone to failure and avoids water pollution and steam usage by other chemical substances, making the deoxygenation method reliable and highly safe.
[0063] In some embodiments, such as Figure 2 As shown, the main structure 10 is a rotationally symmetric body. The outer wall of the main structure 10 has two radially opposite sides with inwardly recessed liquid inlet regions 102. Multiple liquid inlets 101 are arrayed in the liquid inlet regions 102.
[0064] It should be noted that the shape of the main structure 10 proposed in this embodiment is illustrated by a sphere. Of course, the shape of the main structure 10 can also be selected as a cylinder or other rotationally symmetric body according to the actual situation, and is not limited here. The shape of the liquid inlet area 102 proposed in this embodiment is preferably hemispherical. And each liquid inlet 101 is connected to a pipe structure 20.
[0065] In this embodiment, the inwardly recessed liquid inlet area 102 facilitates connection with the water supply pipe 3 of the target device and improves connection stability, ensuring that the water in the water supply pipe 3 can flow smoothly into the pipe structure 20 through the liquid inlet 101.
[0066] Furthermore, a sealing ring can be installed at the connection between the liquid inlet area 102 and the water supply pipe 3 to ensure that the liquid inlet area 102 and the water supply pipe 3 form a sealed connection.
[0067] In some embodiments, such as Figures 1-2 As shown, a partition 103 is provided circumferentially around the equatorial plane of the main structure 10. Multiple sets of discrete structure groups are provided circumferentially on both sides of the partition 103 along the radial direction. Each set of discrete structure groups has multiple discrete structures 30 arranged radially.
[0068] The equatorial plane is perpendicular to the line connecting the center of the opposite liquid inlet region 102.
[0069] It should be noted that, in this embodiment, each discrete structure group is illustrated by having three discrete structures 30 along the radial direction. Of course, depending on the actual situation, each discrete structure group can also have two, four or more discrete structures 30 along the radial direction, which is not limited here.
[0070] Thus, when water breaks and disperses through the discrete structure 30, to prevent the broken and dispersed water from accumulating in the central region outside the main structure 10, baffles 103 are continuously arranged circumferentially around the equatorial plane of the main structure 10. When water from the discrete structure 30 located on both radial sides of the baffles 103 splashes towards the baffles 103, it will be blocked or even bounced off the baffles 103, preventing the water from the discrete structure 30 from accumulating again and affecting the dispersion range of water in the steam generating chamber 1. This increases the contact area between the water flowing out of the discrete structure 30 and the high-temperature steam in the steam generating chamber 1, making the water flowing out of the discrete structure 30 more fully deoxygenated by heating. This allows the water to be quickly heated to saturation by the high-temperature steam and fully release oxygen, thereby increasing the rate of dissolved oxygen release in the water and reducing the oxygen content in the water.
[0071] In some embodiments, such as Figures 3-4 As shown, this embodiment presents the structural composition of the first discrete structure 30:
[0072] The discrete structure 30 includes a rolling groove 301, a rolling element 302, a variable cross-section flow channel 303, and a support element 304;
[0073] Each of the pipe structures 20 has a circumferentially provided rolling groove 301 at the liquid outlet end. Multiple rolling elements 302 are embedded in the rolling groove 301. Each rolling element 302 can rotate radially and / or roll circumferentially relative to the rolling groove 301.
[0074] The inner or outer side of the rolling groove 301 is provided with a plurality of variable cross-section flow channels 303. The outer edge of the variable cross-section flow channel 303 is connected to the inner wall of the corresponding pipe structure 20 through the support member 304. The variable cross-section flow channel 303 and the rolling groove 301 are both in communication with the pipe structure 20.
[0075] It should be noted that this embodiment uses the example of multiple variable cross-section flow channels 303 arrayed on the inner side of the rolling groove 301. The rolling groove 301 is preferably an annular groove, and the rolling element 302 will partially protrude from the side of the rolling groove 301 facing away from the liquid outlet end of the corresponding pipe structure 20, while the side of the rolling groove 301 facing the liquid outlet end of the corresponding pipe structure 20 is connected to the liquid outlet end of the pipe structure 20. The rolling element 302 proposed in this embodiment is preferably a ball.
[0076] In this way, some of the water in the pipe structure 20 flows to the rolling groove 301. When the water flows to the rolling groove 301, the water impacts the rolling element 302, causing the rolling element 302 to rotate radially and / or roll circumferentially relative to the rolling groove 301, so as to convert the viscous resistance between the fluid and the solid into rotational torque. The rotating rolling element 302 generates tangential shear force with the water flow, which disrupts the laminar flow state of the water and induces local turbulence. In addition, the rotating rolling element 302 generates periodically detached Karman vortex streets in the wake region. The alternating vortex shearing causes the water flow to oscillate violently, accelerates the rupture of large liquid masses, and then breaks and disperses the water that has passed through the rolling element 302 before flowing out into the steam generating chamber 1, increasing the dispersion range of water in the steam generating chamber 1.
[0077] Meanwhile, the remaining water in the pipe structure 20 flows to the variable cross-section flow channel 303. The variable cross-section flow channel 303 has a certain angle, which causes the water to flow along the pipe wall and then gather towards the central axis, generating multiple water streams colliding in opposite directions. The collision causes the droplets to deform and stretch, increasing the surface area, thereby increasing the degree of water dispersion and breakage. In turn, the water that has passed through the variable cross-section flow channel 303 is broken and dispersed and flows out into the steam generating chamber 1, increasing the dispersion range of water in the steam generating chamber 1.
[0078] Therefore, this invention increases the dispersion range of water in the steam generating chamber 1 by using the rotating rolling element 302 and the variable cross-section flow channel 303, thereby increasing the contact area between the water flowing out of the rolling element 302 and the variable cross-section flow channel 303 and the high-temperature water vapor in the steam generating chamber 1. This allows the water flowing out of the rolling element 302 and the variable cross-section flow channel 303 to be heated and deoxygenated more fully, so that the water can be quickly heated to saturation by the high-temperature water vapor and oxygen can be fully released, thereby increasing the rate of dissolved oxygen release in the water and reducing the oxygen content in the water.
[0079] Specifically, the radial cross-section of the variable cross-section flow channel 303 gradually decreases along the flow direction of the liquid to be deoxygenated.
[0080] In this way, when the remaining water in the pipe structure 20 flows to the variable cross-section flow channel 303, the water in the variable cross-section flow channel 303 will be accelerated and converge towards the center. According to Bernoulli's equation, the change in flow velocity leads to a pressure gradient, causing the droplets to move along the pipe wall and then converge towards the central axis, generating multiple opposing collisions of water streams. The collisions cause the droplets to deform and stretch, increasing the surface area and thus increasing the degree of water dispersion and breakage. In turn, the water that has passed through the variable cross-section flow channel 303 is broken and dispersed and flows out into the steam generating chamber 1, increasing the dispersion range of water in the steam generating chamber 1.
[0081] It is understandable that the radial cross-section change of the variable cross-section flow channel 303 can also be in the following cases:
[0082] The radial cross-section of the variable cross-section flow channel 303 remains unchanged at the end near the pipe structure 20, while the radial cross-section of the variable cross-section flow channel 303 gradually decreases at the end away from the pipe structure 20.
[0083] In other embodiments, such as Figure 5 As shown, this embodiment proposes a second discrete structure 30 with the following structural composition:
[0084] Discrete structure 30 includes rolling groove 301 and rolling element 302;
[0085] Each of the pipe structures 20 has a circumferentially circumferentially provided rolling groove 301 at the liquid outlet end, and the rolling groove 301 communicates with the pipe structure 20; the rolling groove 301 is embedded with a plurality of rolling elements 302, and the rolling elements 302 can rotate radially and / or roll circumferentially relative to the rolling groove 301.
[0086] In this way, all the water in the pipe structure 20 will flow into the rolling groove 301. When the water flows into the rolling groove 301, it will impact the rolling element 302, causing the rolling element 302 to rotate radially and / or roll circumferentially relative to the rolling groove 301. This converts the viscous resistance between the fluid and the solid into rotational torque. The rotating rolling element 302 generates tangential shear force with the water flow, disrupting the laminar flow state of the water and inducing local turbulence. Furthermore, the rotating rolling element 302 generates periodically shedding Karman vortex streets in the wake region. The alternating shedding of vortices causes the water to... The violent oscillation of the flow accelerates the breakup of large liquid clumps, thereby breaking up and dispersing the water passing through the rolling element 302 before it flows out into the steam generating chamber 1. This increases the dispersion range of the water within the steam generating chamber 1, thereby increasing the contact area between the water flowing out of the rolling element 302 and the high-temperature steam in the steam generating chamber 1. This allows the water flowing out of the rolling element 302 to be heated and deoxygenated more thoroughly, enabling the water to be quickly heated to saturation by the high-temperature steam and fully release oxygen. This, in turn, increases the rate of dissolved oxygen release in the water and reduces the oxygen content in the water.
[0087] In some other embodiments, such as Figure 6As shown, this embodiment proposes a third discrete structure 30:
[0088] Discrete structure 30 includes variable cross-section flow channel 303 and support member 304;
[0089] Each of the pipe structures 20 has multiple variable cross-section flow channels 303 arrayed at its liquid outlet end. Each variable cross-section flow channel 303 is connected to the corresponding pipe structure 20. The outer edge of each variable cross-section flow channel 303 is connected to the inner wall of the corresponding pipe structure 20 through the support member 304.
[0090] In this way, all the water in the pipe structure 20 will flow into the variable cross-section flow channel 303. The radial cross-section of the variable cross-section flow channel 303 gradually decreases along the direction of water flow, causing the water in the variable cross-section flow channel 303 to accelerate and converge towards the center. According to Bernoulli's equation, the change in flow velocity leads to a pressure gradient, causing the droplets to move along the pipe wall and then converge towards the central axis, generating multiple opposing collisions of water streams. The collisions deform and stretch the droplets, increasing their surface area, thereby increasing the degree of water dispersion and breakage. This further breaks up the water that has passed through the variable cross-section flow channel 303 and allows it to flow out into the steam generating chamber 1, increasing the dispersion range of water in the steam generating chamber 1. This increases the contact area between the water flowing out of the variable cross-section flow channel 303 and the high-temperature steam in the steam generating chamber 1, allowing the water flowing out of the variable cross-section flow channel 303 to be heated and deoxygenated more fully. This allows the water to be quickly heated to saturation by the high-temperature steam and fully release oxygen, thereby increasing the rate of dissolved oxygen release in the water and reducing the oxygen content in the water.
[0091] In some embodiments, to further increase the dispersion and fragmentation of the water flowing out of the variable cross-section flow channel 303, such as Figure 7 As shown, the variable cross-section flow channel 303 is provided with multiple layers of staggered sawtooth baffles 305 at the end along the flow direction.
[0092] In this way, the water in the pipe structure 20 will flow entirely into the variable cross-section flow channel 303. The radial cross-section of the variable cross-section flow channel 303 gradually decreases along the direction of water flow, causing the water in the variable cross-section flow channel 303 to accelerate and converge towards the center. According to Bernoulli's equation, the change in flow velocity leads to a pressure gradient, causing the droplets to move along the pipe wall and then converge towards the central axis, generating multiple water streams colliding in opposite directions. At the same time, the multiple water streams will also collide with the staggered sawtooth baffles 305, thereby further increasing the degree of water dispersion and further increasing the dispersion range of water in the steam generating chamber 1.
[0093] In some embodiments, such as Figure 8 As shown, this utility model also proposes a heat pump air conditioner, including a steam generator with a steam generating chamber 1, wherein the steam generating chamber 1 is equipped with the deoxygenation device as described above.
[0094] The steam generator includes a housing 6, a steam generating chamber 1 inside the housing 6, and a heat exchange tube 5 at the bottom of the steam generating chamber 1. A refrigerant outlet 7 and a refrigerant inlet 8 communicating with the heat exchange tube 5 are provided on one side of the housing 6 along the axial direction. An exhaust port 4 communicating with the steam generating chamber 1 is provided on the top wall of the housing 6, and a baffle plate 9 is provided in the steam generating chamber 1 corresponding to the exhaust port 4.
[0095] In this way, under the action of the deoxygenation device, water falls into the steam generation chamber 1 in a dispersed state and gathers at the bottom of the steam generation chamber 1, and comes into contact with the heat exchange tube 5; then the refrigerant circulates between the heat exchange tube 5, the refrigerant outlet 7 and the refrigerant inlet 8, and then the water exchanges heat with the refrigerant in the heat exchange tube 5. The water absorbs the temperature of the refrigerant in the heat exchange tube 5, thereby increasing its temperature. The water changes from liquid to high-temperature water vapor, and then the high-temperature water vapor passes through the baffle plate 9 and is discharged from the steam generator from the exhaust port 4.
[0096] Therefore, this invention increases the dispersion range of water in the steam generating chamber 1 by using the rotating rolling element 302 and the variable cross-section flow channel 303, thereby increasing the contact area between the water flowing out of the rolling element 302 and the variable cross-section flow channel 303 and the high-temperature water vapor in the steam generating chamber 1. This allows the water flowing out of the rolling element 302 and the variable cross-section flow channel 303 to be heated and deoxygenated more fully, so that the water can be quickly heated to saturation by the high-temperature water vapor and oxygen can be fully released, thereby increasing the rate of dissolved oxygen release in the water and reducing the oxygen content in the water.
[0097] Furthermore, the released oxygen will follow the high-temperature steam through the baffle plate 9 and be discharged from the exhaust port 4 of the steam generator, thereby preventing the released oxygen from re-integrating into the deoxygenated water, preventing dissolved oxygen from oxidizing and corroding the metal materials inside the steam generator, avoiding rust from falling off and adhering to the heat exchange tube 5, ensuring heat exchange efficiency, reducing the maintenance and replacement costs of the steam generator, and extending the service life of the steam generator; the deoxygenated water is stored at the bottom of the steam generating chamber 1 so as to exchange heat with the heat exchange tube 5 located at the bottom of the steam generating chamber 1 to continuously generate high-temperature steam.
[0098] In some embodiments, to further ensure sufficient contact between the water flowing out of the deaerator and the high-temperature steam in the steam generating chamber 1, and to increase the contact area, such as... Figure 8 As shown, the top wall of the steam generating chamber 1 is provided with a water inlet 2. The water inlet 2 is connected to the liquid inlet 101 on the main structure 10 through a water supply pipe 3, so that the deoxygenation device is suspended in the steam generating chamber 1.
