Description

Technical Field

[0001] The present invention relates to the technical field of steam generation, and in particular to a thermal deoxidation device and a heat pump air conditioner. Background Art

[0002] Steam generators, due to their high efficiency, reliability, and versatility, play a vital role in many industries. Their core function is to convert water into high-temperature, high-pressure steam through heat transfer tubes between water and a high-temperature refrigerant. By precisely controlling the heating and evaporation of water, the pressure and temperature of the steam can be adjusted to meet the needs of diverse applications, such as industrial production, heating systems, and food processing.

[0003] If the water used to generate steam has a high oxygen content, it may affect equipment and systems. High levels of dissolved oxygen in cooling water accelerate the oxidation and corrosion of metal materials within the heat exchanger, especially susceptible materials like carbon steel. As corrosion products (such as rust) accumulate, they form a coating on the surface of the heat exchange tubes, increasing thermal resistance and reducing heat transfer efficiency. Severe corrosion can also cause heat exchanger leaks.

[0004] In order to reduce the above problems, the water needs to be deoxygenated. The main treatment methods include: adding chemical agents (such as adding deoxygenators) to the water to remove excess oxygen; heating and deoxygenating through external / internal thermal deoxygenation devices, etc.

[0005] The built-in thermal deaerator utilizes steam generated by a steam generator to heat and deoxygenate water. This is a process that removes dissolved oxygen from water through thermal action. The core principle is to directly heat the water with high-temperature steam, raising the water temperature to saturation. At this point, the solubility of dissolved oxygen in the water decreases dramatically, causing oxygen to precipitate from the water.

[0006] However, the inlet water flow of the deoxygenation device in the prior art is relatively concentrated or small, resulting in the inability to quickly saturate the inlet water and fully analyze the dissolved oxygen in the water. Summary of the Invention

[0007] The present invention provides a thermal deoxidation device and a heat pump air conditioner, which are used to solve the problem of slow oxygen release speed of the deoxidation device in the prior art.

[0019] Furthermore, each of the second liquid outlets is correspondingly provided with a first elbow pipe, and the first elbow pipe is used to allow the liquid to be deoxygenated flowing out of the second liquid outlet to face the corresponding first orifice plate.

[0020] Furthermore, the deflector includes:

[0021] A rotating column and a rotating base located at one or both ends of the rotating column;

[0027] Furthermore, the porous structure comprises:

[0028] A porous plate is matched to cover the first liquid outlet, and the porous plate has evenly and densely distributed third through holes.

[0029] Furthermore, the porous structure further comprises:

[0030] A grid assembly is distributed at the end of the first liquid outlet, and the grid assembly is used to divide the liquid to be deoxygenated passing through into sheets.

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly stated. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0060] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0061] In some embodiments, to improve the efficiency of rapid oxygen evolution of the liquid to be deoxygenated, Figure 1-Figure 2 As shown, the present invention proposes a thermal deoxidation device, which is arranged in the steam generating chamber 40 of the target equipment; comprising:

[0062] A plurality of liquid separators 20 are arranged in an annular pattern, and any adjacent liquid separators 20 are connected by pipes 30; each of the liquid separators 20 is provided with a plurality of first liquid outlets 201, and each of the first liquid outlets 201 is adapted to be provided with a porous structure 202, and the porous structure 202 is used to divide the liquid to be deoxygenated passing through into discrete liquid phase units and disperse the flow;

[0063] The flow guide 10 is arranged in the annular space surrounded by the liquid separator 20 (preferably the geometric center of the annular space); the flow guide 10 is used to break up the liquid to be deoxygenated flowing thereto and diffuse it to the surrounding area;

[0064] Each of the liquid separators 20 corresponding to the flow guide 10 is provided with a second liquid outlet 203 ; at least one of the liquid separators 20 is provided with a liquid inlet 204 .

[0065] It should be noted that the target device proposed in this embodiment is preferably a steam generator, and the liquid to be deoxygenated is preferably water. Furthermore, this embodiment uses four liquid separators 20 arranged in a circular shape and evenly distributed, with two oppositely disposed liquid separators 20 each having a liquid inlet 204, and each liquid separator 20 having multiple first liquid outlets 201 circumferentially provided. Of course, the annularly distributed liquid separators 20 can also be square, elliptical, or other suitable annular shapes, which are not limited here. The flow guide 10 is fixedly connected to the pipeline 30 via a support frame.

[0066] Among them, external water flows into multiple liquid separators 20 distributed in a ring shape through the liquid inlet 204, and part of the water will flow into all the first liquid outlets 201, and then be forced to flow through a narrow channel by the porous structure 202 on the first liquid outlet 201, and break into small droplets (equivalent to discrete liquid phase units) after overcoming the critical point of surface tension (segmentation stage), and then the small droplets interact with the gas under the inertial force (such as air shear) and are diffusely distributed (dispersion stage); then the remaining part of the water is sprayed from the second liquid outlet 203 of each liquid separator 20 to the deflector 10, and the deflector 10 will break up the water flow sprayed to it into small streams or discrete liquid phase units according to its own structure, and then diffuse and distribute to the surrounding area.

[0067] Therefore, the thermal deoxygenation device proposed in the present invention can be sprayed to the deflector 10 through the porous structure 202 on the first liquid outlet 201 and the second liquid outlet 203, thereby increasing the dispersion area of ​​discrete liquid phase units or small streams of water in the steam generating chamber 40, making their diffusion range wider. In this way, the contact area between the water flowing out of the thermal deoxygenation device and the high-temperature water vapor in the steam generating chamber 40 can be increased, so that the liquid to be deoxygenated can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully release oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0068] The water is quickly heated to a saturated state by the high-temperature steam and fully releases oxygen. The released oxygen is discharged from the steam outlet 100 at the top of the target device along with the rising steam, thereby reducing the dissolved oxygen content in the water, preventing the dissolved oxygen from oxidizing and corroding the metal materials inside the target device, and preventing the rust on the metal materials from falling off and adhering to the heat exchange tube 60 of the target device, thereby ensuring the heat exchange efficiency and extending the service life of the target device. The deoxygenated water is stored in the water storage area so that the target device can generate high-temperature steam in subsequent steps.

[0069] Compared with an external thermal deoxygenator, this embodiment places the thermal deoxygenator inside the steam generating chamber 40 of the target equipment, which can greatly improve space utilization without occupying additional external space. The high-temperature water vapor itself has a high temperature, and the high-temperature water vapor can be directly used as a heat source for thermal deoxygenation without providing an additional heat source for the thermal deoxygenator. The thermal deoxygenation method is not prone to failure and can prevent other chemical substances from contaminating the water quality and affecting the use of water vapor. The deoxygenation method is reliable and safe.

[0070] In some embodiments, as Figure 2-Figure 3 As shown, this embodiment proposes a first structure of a flow deflector 10, which includes:

[0071] A spherical main structure 101, wherein the outer surface of the main structure 101 is provided with arc-shaped ridges 102 protruding outward along three axes, dividing the outer surface of the main structure 101 into a plurality of spherical triangular areas 103;

[0072] The rib 102 is connected to the pipe 30 via a first support rod 104;

[0073] When the liquid to be deoxygenated flows toward the main structure 101 , it flows in various directions along the spherical triangular area 103 .

[0074] It should be noted that the ridges 102 on the surface of the main structure 101 are close to and directly opposite the second liquid outlet 203 of the liquid separator 20. Furthermore, in this embodiment, all three-axis intersections of the ridges 102 are connected to the pipe 30 via the first support rod 104, and the pipe 30 is then fixed to the steam generating chamber 40 via a support frame; alternatively, the thermal deoxidizer is fixed to the steam generating chamber 40 via the liquid inlet 204; alternatively, the two-axis intersections of the ridges 102 are used to fix the thermal deoxidizer to the steam generating chamber 40 via a support frame, which is not limited here.

[0075] The outer surface of the main structure 101 is provided with arc-shaped ridges 102 protruding outward along the three-axis directions. The arc-shaped ridges 102 divide the outer surface of the main structure 101 into eight congruent spherical triangular areas 103. Each spherical triangular area 103 is defined by three arc-shaped ridges 102 segments, and the internal angles are all 90 degrees.

[0076] In this way, when water is sprayed from the second liquid outlet 203 of each liquid separator 20 to the deflector 10, it will be separated into several small streams of water by the ridges 102 on the surface of the main structure 101. The small streams of water will form a liquid film on the surface of the main structure 101 and flow in all directions along the spherical triangular area 103, thereby increasing the dispersion area of ​​the small streams of water in the steam generating chamber 40 and making their diffusion range wider. In this way, the contact area between the water flowing out of the second liquid outlet 203 and the high-temperature water vapor in the steam generating chamber 40 can be increased, so that the deoxygenated liquid can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0077] In other embodiments, Figure 4-Figure 5 As shown, this embodiment proposes a second structure of the deflector 10, which includes:

[0078] The outer surface of the support column 105 is matched with a first orifice plate 106 along the axial direction corresponding to each of the liquid dispensers 20, and the first orifice plate 106 has first through holes 1061 that are evenly and densely distributed;

[0079] At least two of the first orifice plates 106 are connected to the pipeline 30 via second support rods 107 .

[0080] It should be noted that, in this embodiment, one or both axial ends of the support column 105 secure the thermal deaerator to the steam generating chamber 40 via a support frame; alternatively, the pipeline 30 secures the thermal deaerator to the steam generating chamber 40 via a support frame; or alternatively, the thermal deaerator is secured within the steam generating chamber 40 via the liquid inlet 204, without limitation. Furthermore, this embodiment uses the example of each edge of the first orifice plate 106 being connected to the pipeline 30 via the second support rod 107.

[0081] The first through holes 1061 on the first orifice plate 106 are arranged in an array. In this embodiment, the length direction of the first through holes 1061 is perpendicular to the first orifice plate 106. Of course, the length direction of the first through holes 1061 can also be inclined relative to the first orifice plate 106 according to actual conditions, which is not limited here. All first orifice plates 106 are arranged in a "cross" or "M" shape on the support column 105.

[0082] In this way, when water is sprayed from the second liquid outlet 203 of each liquid separator 20 to the deflector 10, it will be broken up into discrete liquid phase units by the first through hole 1061 of the corresponding first orifice plate 106 and diffused and distributed to the surrounding area, thereby increasing the dispersion area of ​​the discrete liquid phase units in the steam generating chamber 40 and making its diffusion range wider. In this way, the contact area between the water flowing out of the second liquid outlet 203 and the high-temperature water vapor in the steam generating chamber 40 can be increased, so that the deoxygenated liquid can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0083] Specifically, in order to further ensure that the water flowing out of the second liquid outlet 203 can face the corresponding first orifice plate 106, so that the water flow can be fully broken up into discrete liquid phase units, such as Figure 4 As shown, each of the second liquid outlets 203 is correspondingly provided with a first elbow pipe 108 , and the first elbow pipe 108 is used to allow the liquid to be deoxygenated flowing out of the second liquid outlet 203 to face the corresponding first orifice plate 106 .

[0084] In some further embodiments, Figure 6-Figure 7 As shown, this embodiment proposes a third structural composition of the deflector 10, which includes:

[0085] A rotating column 109 and a rotating base 110 located at one or both ends of the rotating column;

[0086] The outer surface of the rotating column 109 is matched with a second orifice plate 111 corresponding to each of the liquid dispensers 20 , and the second orifice plate 111 has second through holes 1111 that are evenly and densely distributed;

[0087] The rotating base 110 is connected to the pipe 30 via a third support rod 112;

[0088] The rotating column 109 can drive the second orifice plate 111 to rotate relative to the rotating base 110 .

[0089] It should be noted that in this embodiment, at least one rotating base 110 secures the thermal deaerator to the steam generating chamber 40 via a support frame; alternatively, the pipeline 30 secures the thermal deaerator to the steam generating chamber 40 via a support frame; alternatively, the thermal deaerator is secured within the steam generating chamber 40 via the liquid inlet 204, without limitation. Furthermore, all second orifice plates 111 are arranged on the rotating column 109 in a cross or M-shaped configuration.

[0090] In this way, when water is sprayed from the second liquid outlet 203 of each liquid separator 20 to the second orifice plate 111, the water flow hits the corresponding unperforated area of ​​the second orifice plate 111 (the unperforated area is equivalent to the area between adjacent second through holes 1111), which can spontaneously drive the rotating column 109 and the second orifice plate 111 to rotate; and the water flow hits the open area of ​​the corresponding second orifice plate 111, it will be broken up into discrete liquid phase units, and because the second orifice plate 111 rotates, the diffusion direction of the discrete liquid phase units can be changed, so that the discrete liquid phase units are diffused and distributed more widely around the deflector 10, thereby increasing the dispersion area of ​​the discrete liquid phase units in the steam generating chamber 40, so that the contact area between the water flowing out of the second liquid outlet 203 and the high-temperature water vapor in the steam generating chamber 40 can be increased, so that the deoxygenated liquid can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0091] Specifically, in order to further ensure that the water flowing out of the second liquid outlet 203 can face the corresponding second orifice plate 111, so that the water flow can be fully broken up into discrete liquid phase units, such as Figure 6 As shown, each second liquid outlet 203 is correspondingly provided with a second elbow pipe 113 , and the second elbow pipe 113 is used to allow the liquid to be deoxygenated flowing out of the second liquid outlet 203 to face the corresponding second orifice plate 111 .

[0092] Specifically, the second through holes 1111 are all tilted on the second orifice plate 111 , and the axes of the second through holes 1111 are tilted radially outward relative to the rotating column 109 .

[0093] In this way, when water is sprayed from the second liquid outlet 203 of each liquid distributor 20 to the second orifice plate 111, the water flow hits the corresponding non-opening area of ​​the second orifice plate 111, which can spontaneously drive the rotating column 109 and the second orifice plate 111 to rotate; and the water flow hits the opening area of ​​the corresponding second orifice plate 111, which will be broken up into discrete liquid phase units. At the same time, since the length direction of the second through hole 1111 is inclined to the second orifice plate 111 and faces all around (equivalent to the axis of the second through hole 1111 being inclined radially outward relative to the rotating column 109), In the process of rotation of the second orifice plate 111, the kinetic energy is transferred to the droplets flying out obliquely along the second through hole 1111, which can change the diffusion direction of the discrete liquid phase units, so that the discrete liquid phase units are diffused and distributed in a wider range around the deflector 10, thereby increasing the contact area between the water flowing out of the second liquid outlet 203 and the high-temperature water vapor in the steam generating chamber 40, so that the deoxygenated liquid can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0094] Of course, the axis of the second through hole 1111 can also be tilted radially inward relative to the rotating column 109, or the length of the second through hole 1111 can be perpendicular to the first orifice plate 106, which is not limited here.

[0095] In other embodiments, Figure 8 As shown, the thermal deoxygenation device proposed in this embodiment can remove the deflector 10, so that water flows into multiple liquid separators 20 distributed in a ring through the liquid inlet 204, and part of the water will flow into all the first liquid outlets 201, and then be forced by the porous structure 202 on the first liquid outlet 201 to flow through the narrow channel, and break into small droplets after overcoming the critical point of surface tension. Then, the small droplets interact with the gas under the inertial force (such as air shear), and are diffused and distributed in the steam generating chamber 40, and then the remaining water will be directly sprayed out from the second liquid outlet 203 into the steam generating chamber 40.

[0096] Of course, the second liquid outlet 203 can also be removed (eg Figure 9 As shown), it is ensured that water is sprayed out only from the first liquid outlet 201, which is not limited here.

[0097] In some embodiments, as Figure 1 and Figure 10 As shown, the porous structure 202 includes:

[0098] A porous plate 2021 is matched to cover the first liquid outlet 201 , and the porous plate 2021 has third through holes 2022 that are evenly and densely distributed.

[0099] In this way, when water flows out from the first liquid outlet 201, the water flow from the first liquid outlet 201 will be forced to flow through the third through hole 2022 on the porous plate 2021, and after overcoming the critical point of surface tension, it will break into discrete liquid phase units and spray out. Then, the discrete liquid phase units will interact with the gas (such as air shear) under the inertial force and be diffusely distributed. This can increase the contact area between the water flowing out of the first liquid outlet 201 and the high-temperature water vapor in the steam generating chamber 40, so that the deoxygenated liquid can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0100] Furthermore, in order to ensure that the water flow in the first liquid outlet 201 can be more easily and fully broken up into discrete liquid phase units, as Figure 10 As shown, the porous structure 202 further includes:

[0101] A grid assembly 2023 is disposed at the end of the first liquid outlet 201 , and the grid assembly 2023 is used to divide the liquid to be deoxygenated passing through into sheets.

[0102] It should be noted that the grid assembly 2023 is composed of a plurality of long grids, and the long grids are spaced apart and distributed on the opening at the end of the first liquid outlet 201 .

[0103] In this way, when water flows out from the first liquid outlet 201, the water flow from the first liquid outlet 201 will first pass through the grille assembly 2023 and be cut into sheets, and then the sheet water flow will be forced to flow through the third through hole 2022 on the porous plate 2021, and after overcoming the critical point of surface tension, it will break into discrete liquid phase units and spray out. Then, the discrete liquid phase units are subjected to the interaction between the inertial force and the gas (such as air shear) and are diffusely distributed. This can increase the contact area between the water flowing out of the first liquid outlet 201 and the high-temperature water vapor in the steam generating chamber 40, so that the deoxygenated liquid can be heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0104] In some embodiments, as Figure 1 As shown, the present invention also proposes a heat pump air conditioner, comprising a steam generator, wherein the thermal deoxidation device as described above is installed in the steam generator.

[0105] It can be understood that the steam generator proposed in this embodiment also includes a shell 50, a heat exchange tube 60, a gas-liquid separator 70, a refrigerant inlet 80, a refrigerant outlet 90, and a steam outlet 100; wherein, a heat exchange tube 60 is provided at the bottom of the shell 50, and the internal space of the shell 50 located above the heat exchange tube 60 is a steam generating chamber 40, and a thermal deoxidation device is installed in the steam generating chamber 40; a refrigerant inlet 80 and a refrigerant outlet 90 connected to the heat exchange tube 60 are provided at one end of the shell 50 along the axial direction; a steam outlet 100 communicating with the steam generating chamber 40 is provided at the top of the shell 50, and a gas-liquid separator 70 is provided in the steam generating chamber 40 corresponding to the steam outlet 100.

[0106] In this way, water flows into a plurality of liquid separators 20 distributed in a ring shape through the liquid inlet 204, and then the water passes through the porous structure 202 and the flow guide 10 to break up the water flow into sheets, films, and drops, so that the water flow is diffused and distributed in the steam generating chamber 40 with a smaller volume (equivalent to small streams or discrete liquid phase units) when flowing out of the first liquid outlet 201 and the second liquid outlet 203. This can increase the contact area between the water flowing out of the first liquid outlet 201 and the second liquid outlet 203 and the high-temperature water vapor in the steam generating chamber 40, so that the deoxygenated liquid is heated and deoxygenated more fully, so that the water can be quickly heated to a saturated state by the high-temperature water vapor and fully precipitate oxygen, thereby increasing the precipitation rate of dissolved oxygen in the water.

[0107] At the same time, the separated oxygen is discharged from the steam outlet 100 along with the rising water vapor, and the deoxygenated water is stored in the water storage area so that in the subsequent steps, it can undergo phase change with the heat exchange tube 60 to generate high-temperature water vapor.

[0108] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein. Any equivalent structure made using the contents of the present invention specification and drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the present invention.
