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] Horizontal tube flooded evaporators have gradually become a core component of high-temperature steam heat pump units due to their low cost, simple structure, high stability, and large cooling capacity. When operating as a steam generator, the liquid water outside the heat exchange tubes is heated into high-temperature steam by the high-temperature refrigerant inside the tubes, while external feedwater continuously enters the shell side to replenish the water supply. In this process, the quality of the shell-side water largely determines the durability and safety of the steam generator. Excessive dissolved oxygen in the feedwater can cause severe oxidation and corrosion of the shell and tube materials, potentially leading to serious accidents. Therefore, feedwater deoxygenation is an essential and crucial step in steam production systems.

[0003] Currently, water deoxygenation methods are mainly divided into physical deoxygenation and chemical deoxygenation. The former mainly includes thermal deoxygenation and vacuum deoxygenation, while the latter mainly includes deoxygenation using iron filings and chemical agents. Among these, thermal deoxygenation is widely used due to its low cost, ability to remove dissolved oxygen and other gases from water simultaneously, and lack of residue. Thermal deoxygenation is based on the Henry Dalton theorem, which states that the closer water is to saturation, the lower its oxygen content. Therefore, a portion of the produced high-temperature steam can be used to heat the water to saturation, thus achieving deoxygenation.

[0004] Existing conventional steam generators cannot efficiently utilize the high-temperature steam in existing steam generators to promote the rapid release of dissolved oxygen. 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 high-temperature water vapor cannot be efficiently utilized 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] A first shell, a second shell, and a third shell are sequentially nested from the inside out; the first shell and the second shell are spaced apart to form a first shell side that communicates with the air intake pipe, and the second shell and the third shell are spaced apart to form a second shell side;

[0008] The first housing has a cavity communicating with the liquid supply pipe, and the cavity has multiple radially extending flow guiding components that completely cover its radial cross section along the axial direction;

[0009] The top wall of the first housing is provided with a plurality of flow guiding film forming components along the axial direction, the liquid inlet of which is connected to the cavity and the liquid outlet of which is connected to the second housing side;

[0011] Furthermore, the flow guiding component includes a baffle and a first flow guiding body;

[0012] The cavity is provided with multiple radially extending baffles that completely cover its radial cross section along the axial direction. The baffles are provided with multiple third through holes along the axial direction. Each third through hole is fitted with a first flow guide body. Each first flow guide body is provided with multiple liquid inlet channels and one liquid outlet channel along the flow direction of the liquid to be deoxygenated in the cavity. The liquid outlet channel is connected to all the liquid inlet channels.

[0013] Furthermore, the radial cross-section of the liquid inlet channel gradually decreases along the flow direction of the liquid to be deoxygenated.

[0014] Furthermore, the flow-guiding film-forming component includes a second flow-guiding body, which sequentially seals through the first housing and the second housing;

[0015] Each of the second guide bodies has multiple axially extending liquid inlet channels in the circumferential direction and multiple radially extending liquid outlet channels in the circumferential direction. The beginning of all the liquid outlet channels and the end of all the liquid inlet channels converge in the communicating cavity within the second guide body.

[0016] The beginning of each liquid inlet channel is connected to the cavity, and the end of each liquid outlet channel is connected to the second shell side.

[0017] Furthermore, the radial cross-section of all the said inlet channels gradually decreases along the flow direction of the liquid to be deoxygenated.

[0018] Furthermore, the outer wall of the second housing is arrayed with multiple first through holes.

[0019] Furthermore, a first support member extending axially is provided between the inner bottom wall of the second housing and the corresponding first housing, and a second support member extending axially is provided between the inner bottom wall of the third housing and the corresponding second housing, and the first support member and the second support member are respectively connected to the corresponding housing on both sides in the radial direction.

[0020] 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.

[0021] Furthermore, a heat exchange tube is provided at the bottom of the steam generating chamber, and the heat exchange tube is connected to the inner wall of the steam generating chamber through a third support member;

[0022] The third support member is also connected to the third housing via a fourth support member.

[0023] Furthermore, an air inlet pipe is installed on the outer side of the housing of the steam generator, and an air extraction component is matched inside the air inlet pipe. The air inlet of the air inlet pipe is connected to the steam generating chamber, and the air outlet of the air inlet pipe is connected to the first housing side.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] This invention employs a triple deoxygenation method, which involves the liquid to be deoxygenated colliding and flowing with the flow guiding component, colliding and flowing with the flow guiding film forming component, and forming a liquid film on the outer wall of the second shell. This results in more thorough deoxygenation of the liquid to be deoxygenated by heating, allowing the liquid to be rapidly heated to saturation by high-temperature steam and fully releasing oxygen. This increases the rate of dissolved oxygen release from the liquid to be deoxygenated, thereby reducing the oxygen content in the liquid to be deoxygenated. Attached Figure Description

[0047] 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.

[0048] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0049] To efficiently utilize high-temperature water vapor to promote rapid release of dissolved oxygen, in some embodiments, such as Figures 1-3 As shown, this utility model proposes a deoxygenation device, which is installed in the steam generation chamber 1 of the target equipment. The deoxygenation device includes:

[0050] A first shell 10, a second shell 20, and a third shell 30 are sequentially fitted from the inside out; the first shell 10 and the second shell 20 are spaced apart to form a first shell side 40 that communicates with the air intake pipe 60, and the second shell 20 and the third shell 30 are spaced apart to form a second shell side 50.

[0051] The first housing 10 has a cavity 101 that communicates with the liquid supply pipe 70. The cavity 101 has a plurality of radially extending flow guiding components 80 that completely cover its radial cross section along the axial direction.

[0052] The top wall of the first housing 10 is provided with a plurality of flow guiding film forming components 90 along the axial direction, the liquid inlet of which is connected to the cavity 101 and the liquid outlet is connected to the second housing side 50;

[0053] The second housing 20 is provided with a plurality of first through holes 201, and the bottom wall of the third housing 30 is provided with a plurality of second through holes 301.

[0054] 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.

[0055] In this embodiment, the first shell 10, the second shell 20 and the third shell 30 are preferably cylindrical, and are coaxially sleeved and horizontally placed from the inside to the outside; the first shell side 40 and the second shell side 50 are preferably annular; the cavity 101 is preferably cylindrical.

[0056] Among them, such as Figure 3 As shown, the first housing 10 is sealed with a first cover plate 102 at both ends along the axial direction, the second housing 20 is sealed with a second cover plate 203 at both ends along the axial direction, and the third housing 30 is sealed with a third cover plate 304 at both ends along the axial direction. The intake pipe 60 passes through the third cover plate 304 and the second cover plate 203 located at the same end in sequence, and the intake pipe 60 does not extend out of the second cover plate 203, so that the intake pipe 60 is connected to the first housing 40, and the penetration points of the intake pipe 60 with the third cover plate 304 and the second cover plate 203 are sealed. Similarly, the liquid supply pipe 70 will pass through the third cover plate 304, the second cover plate 203 and the first cover plate 102 located at the other end in sequence, and the liquid supply pipe 70 does not extend out of the first cover plate 102, so that the liquid supply pipe 70 is connected to the cavity 101, and the penetration points of the liquid supply pipe 70 with the third cover plate 304, the second cover plate 203 and the first cover plate 102 are all sealed.

[0057] Among them, such as Figure 4As shown, when the deoxygenation device needs to deoxygenate the liquid to be deoxygenated, firstly, high-temperature steam from the steam generation chamber 1 is injected into the first shell side 40 through the inlet pipe 60; simultaneously, the liquid to be deoxygenated is injected into the cavity 101 through the liquid supply pipe 70. Then, the liquid to be deoxygenated in the cavity 101 will sequentially pass through the guide component 80 along the axial direction, entering the collision deoxygenation stage. At this time, the liquid to be deoxygenated will collide with the guide component 80, improving the contact effect between the high-temperature steam and the liquid to be deoxygenated, enhancing the steam heat exchange in this process, ensuring the initial deoxygenation effect of the liquid to be deoxygenated, and forming the first stage of deoxygenation; then, the liquid to be deoxygenated after the first stage of deoxygenation will pass through the corresponding guide film forming component 90. During this process, the liquid to be deoxygenated will collide with the guide film forming component 90 and be discharged to... Within the second shell 50, the liquid to be deoxygenated collides with the flow-guiding film-forming component 90, which further enhances the contact effect between the high-temperature water vapor and the liquid to be deoxygenated, and further strengthens the steam heat exchange in this process, ensuring the second deoxygenation effect of the liquid to be deoxygenated, forming a second deoxygenation. Then, the liquid to be deoxygenated after the second deoxygenation and flowing out from the flow-guiding film-forming component 90 will form a liquid film on the outer wall of the second shell 20, further increasing the contact area between the liquid to be deoxygenated and the high-temperature water vapor, forming a third deoxygenation. Then, the liquid to be deoxygenated after the third deoxygenation (equivalent to the deoxygenated liquid) will flow out from the second through hole 301 on the bottom wall of the third shell 30 into the steam generating chamber 1, so that the target equipment can continuously generate high-temperature water vapor from the deoxygenated liquid in subsequent steps.

[0058] The first and second stages of deoxygenation are equivalent to collision deoxygenation, while the third stage of deoxygenation is equivalent to combination deoxygenation.

[0059] Therefore, this invention can form a triple deoxygenation measure by colliding the liquid to be deoxygenated with the flow guiding component 80, colliding with the flow guiding film forming component 90, and forming a liquid film on the outer side wall of the second housing 20. This makes the liquid to be deoxygenated more fully by heating, and allows the liquid to be deoxygenated to be quickly heated to saturation by high-temperature water vapor and fully release oxygen, thereby increasing the release rate of dissolved oxygen in the liquid to be deoxygenated and reducing the oxygen content in the liquid to be deoxygenated.

[0060] In some embodiments, such as Figures 5-6 As shown, the flow guiding component 80 includes a baffle 801 and a first flow guiding body 802;

[0061] The cavity 101 is provided with a plurality of radially extending baffles 801 along the axial direction, which completely cover its radial cross section. The baffles 801 are provided with a plurality of third through holes 803 along the axial direction. Each third through hole 803 is fitted with a first flow guide body 802. Each first flow guide body 802 is provided with a plurality of liquid inlet channels 804 and a liquid outlet channel 805 along the flow direction of the liquid to be deoxygenated in the cavity 101. The liquid outlet channel 805 communicates with all the liquid inlet channels 804.

[0062] It is understandable that the edge of the baffle 801 may be welded, snap-fitted, or otherwise fixedly connected to the inner wall of the cavity 101, which is not limited here. Of course, a sealing structure may also be provided between the edge of the baffle 801 and the inner wall of the cavity 101.

[0063] It should be noted that the cavity 101 is divided into multiple small spaces by the baffle 801, and each small space has at least one flow guiding and film forming component 90 on its top wall. The small space closest to the liquid supply pipe 70 (equivalent to the small space between the first cover plate 102 with the liquid supply pipe 70 and the adjacent baffle 801) is not provided with a flow guiding and film forming component 90. Furthermore, the shape of the first flow guiding body 802 proposed in this embodiment is preferably cylindrical.

[0064] In this way, the liquid to be deoxygenated in the cavity 101 can only flow through the flow channel in the first guide body 802. When the liquid to be deoxygenated enters the first guide body 802 from multiple inlet channels 804 at the same time, they will converge and collide in the same outlet channel 805 and then flow to the next small space. This collision improves the contact effect between high-temperature water vapor and the liquid to be deoxygenated, strengthens the water vapor heat exchange in this process, ensures the initial deoxygenation effect of the liquid to be deoxygenated, and forms the first deoxygenation.

[0065] Specifically, the radial cross-section of the liquid inlet channel 804 gradually decreases along the flow direction of the liquid to be deoxygenated.

[0066] In this way, when the liquid to be deoxygenated flows in the inlet channel 804, the radial cross-section of the inlet channel 804 gradually decreases along the flow direction, causing the liquid to be deoxygenated in the inlet channel 804 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 flow. The collisions deform and stretch the droplets, and then the liquid to be deoxygenated in the inlet channel 804 will converge in the outlet channel 805 and collide, thereby improving the collision effect of the liquid to be deoxygenated, further improving the contact effect between the high-temperature water vapor and the liquid to be deoxygenated, strengthening the water vapor heat exchange in this process, and better ensuring the initial deoxygenation effect of the liquid to be deoxygenated, forming the first stage of deoxygenation.

[0067] In some embodiments, such as Figure 3 and Figure 7 As shown, the flow guiding film forming component 90 includes a second flow guiding body 901, which sequentially seals through the first housing 10 and the second housing 20.

[0068] Each of the second flow guide bodies 901 has a plurality of axially extending liquid inlet channels 902 in the circumferential direction, and each of the second flow guide bodies 901 has a plurality of radially extending liquid outlet channels 903 in the circumferential direction. The beginning of all the liquid outlet channels 903 and the end of all the liquid inlet channels 902 converge in the connecting cavity 904 in the second flow guide body 901.

[0069] The beginning of each liquid inlet channel 902 is connected to the cavity 101, and the end of each liquid outlet channel 903 is connected to the second shell side 50.

[0070] It should be noted that the second flow guide body 901 proposed in this embodiment is preferably cylindrical. The second flow guide body 901 sequentially penetrates the top wall of the first housing 10 and the top wall of the second housing 20, and the penetration points of the second flow guide body 901 with the top walls of the first housing 10 and the second housing 20 are sealed. One end of the second flow guide body 901 with the inlet channel 902 does not extend beyond the top wall of the first housing 10, while the second flow guide body 901 extends beyond the top wall of the second housing 20. The ends of all outlet channels 903 are located on the side wall of the second flow guide body 901 extending beyond the top wall of the second housing 20, so that the deoxygenated liquid flowing out of the outlet channels 903 can better enter the second shell side 50. Furthermore, all the outlet channels 903 and inlet channels 902 proposed in this embodiment form a three-dimensional intersecting network within the second flow guide body 901.

[0071] In this way, when the liquid to be deoxygenated in the cavity 101 simultaneously enters the second guide body 901 from multiple inlet channels 902, they will collide and converge in the connecting cavity 904. After the collision, the liquid to be deoxygenated will flow out through the outlet channel 903 to the second shell side 50. This collision further enhances the contact effect between the high-temperature steam and the liquid to be deoxygenated, further strengthening the steam heat exchange in this process and ensuring the second deoxygenation effect of the liquid to be deoxygenated, forming the second deoxygenation. Then, the liquid to be deoxygenated flowing out from the outlet channel 903 will spread outwards, forming a liquid film on the outer wall of the second shell 20, further increasing the contact area between the liquid to be deoxygenated and the high-temperature steam, forming the third deoxygenation. This makes the liquid to be deoxygenated more fully by heating, allowing the liquid to be deoxygenated to be quickly heated to saturation by the high-temperature steam and fully releasing oxygen, thereby increasing the release rate of dissolved oxygen in the liquid to be deoxygenated and reducing the oxygen content in the liquid to be deoxygenated.

[0072] Specifically, the radial cross-section of all the liquid inlet channels 902 gradually decreases along the flow direction of the liquid to be deoxygenated.

[0073] In this way, when the liquid to be deoxygenated flows in the inlet channel 902, the radial cross-section of the inlet channel 902 gradually decreases along the flow direction, causing the liquid to be deoxygenated in the inlet channel 902 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, thereby better improving the collision effect of the liquid to be deoxygenated, further improving the contact effect between the high-temperature water vapor and the liquid to be deoxygenated, strengthening the water vapor heat exchange in this process, and better ensuring the secondary deoxygenation effect of the liquid to be deoxygenated, forming a second deoxygenation.

[0074] In some embodiments, such as Figure 5 As shown, the outer side wall of the second housing 20 has a plurality of first through holes 201 arranged in an array across the entire area.

[0075] This makes it easier for the high-temperature water vapor in the first shell 40 to heat the liquid film formed on the outer wall of the second shell 20, so that the liquid to be deoxygenated is heated and deoxygenated more fully. This allows the liquid to be deoxygenated to be quickly heated to saturation by the high-temperature water vapor and oxygen to be released, thereby increasing the rate of dissolved oxygen release in the liquid to be deoxygenated and reducing the oxygen content in the liquid to be deoxygenated.

[0076] It is understandable that because the intake pipe 60 continuously supplies high-temperature water vapor to the first shell side 40, the liquid to be deoxygenated cannot enter the first shell side 40 through the first through hole 201. Moreover, the water vapor in the first shell side 40 will pass through the first through hole 201 and the second through hole 301 in sequence before being discharged into the steam generating chamber 1. This allows the water vapor after the liquid to be deoxygenated to participate in the circulation again, realizing the recycling of water vapor and effectively reducing steam waste.

[0077] In some embodiments, to ensure the stability of the first housing 10, the second housing 20, and the third housing 30 sequentially nested from the inside out, such as... Figure 2 and Figure 5 As shown, a first support member 202 extending axially is provided between the inner bottom wall of the second housing 20 and the corresponding first housing 10, and a second support member 302 extending axially is provided between the inner bottom wall of the third housing 30 and the corresponding second housing 20, and the first support member 202 and the second support member 302 are respectively connected to the corresponding housing on both sides in the radial direction.

[0078] It should be noted that the axial extension length of the first support member 202 is greater than the axial length of the first housing 10, and the axial extension length of the second support member 302 is greater than the axial length of the second housing 20.

[0079] Furthermore, the radial connections between the first support member 202 and the inner bottom wall of the corresponding second housing 20 and the outer bottom wall of the first housing 10 are welded, bolted, or otherwise stable, and are not limited herein. Similarly, the radial connections between the second support member 302 and the inner bottom wall of the corresponding third housing 30 and the outer bottom wall of the second housing 20 are welded, bolted, or otherwise stable, and are not limited herein.

[0080] In some embodiments, such as Figure 1 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.

[0081] Thus, when the heat pump air conditioner starts, the steam generator starts accordingly, and the steam generation chamber 1 continuously generates high-temperature steam. At this time, the high-temperature steam in the steam generation chamber 1 is first injected into the first shell side 40 through the air inlet pipe 60; simultaneously, the liquid to be deoxygenated is injected into the cavity 101 through the liquid supply pipe 70. Then, the liquid to be deoxygenated in the cavity 101 passes through the guide component 80 axially. During this process, the liquid to be deoxygenated collides with the guide component 80, improving the contact effect between the high-temperature steam and the liquid to be deoxygenated, enhancing the steam heat exchange in this process, and ensuring the initial deoxygenation effect of the liquid to be deoxygenated, forming the first stage of deoxygenation. Then, the liquid to be deoxygenated after the first stage of deoxygenation passes through the corresponding guide film forming component 90. During this process, the liquid to be deoxygenated collides with the guide film forming component 90 and is discharged into the second shell side 50. The liquid to be deoxygenated collides with the guide film forming component 90 during this process. The collision further enhances the contact effect between the high-temperature steam and the liquid to be deoxygenated, strengthening the steam heat exchange process and ensuring the second deoxygenation effect of the liquid, forming a second deoxygenation. Then, the liquid to be deoxygenated, after the second deoxygenation and flowing out from the guide film forming component 90, forms a liquid film on the outer wall of the second shell 20, further increasing the contact area between the liquid to be deoxygenated and the high-temperature steam, forming a third deoxygenation. Thus, through the above three deoxygenation measures, the liquid to be deoxygenated is heated and deoxygenated more thoroughly, allowing the liquid to be quickly heated to saturation by high-temperature steam and fully releasing oxygen, thereby increasing the release rate of dissolved oxygen in the liquid to be deoxygenated, reducing the oxygen content in the liquid to be deoxygenated, and preventing dissolved oxygen from oxidizing and corroding the metal materials inside the steam generator, reducing the maintenance and replacement costs of the steam generator, and extending the service life of the steam generator.

[0082] In some embodiments, to ensure that the deaerator can be stably fixed inside the steam generating chamber 1, such as... Figure 2 As shown, a heat exchange tube 2 is provided at the bottom of the steam generating chamber 1, and the heat exchange tube 2 is connected to the inner wall of the steam generating chamber 1 through a third support member 3;

[0083] The third support member 3 is also connected to the third housing 30 via a fourth support member 303.

[0084] It is understood that the third support member 3 is connected to the third housing 30 through the fourth support member 303. This connection is preferably welded, bolted or otherwise fixed, and is not limited here.

[0085] In some embodiments, such as Figure 8 As shown, an air inlet pipe 60 is installed on the outer side of the outer shell 4 of the steam generator. An air extraction component 5 is matched with the air inlet pipe 60. The air inlet of the air inlet pipe 60 is connected to the steam generating chamber 1, and the air outlet of the air inlet pipe 60 is connected to the first shell side 40.

[0086] It should be noted that the air inlet of the air inlet pipe 60 is preferably located on the steam outlet 6. When the water vapor in the first shell side 40 enters the second shell side 50 through the first through hole 201, the liquid film on the outer wall of the second shell 20 will be broken into small droplets and blown away. The blown-away droplets will be blocked by the third shell 30 to prevent the droplets from being sucked into the air inlet of the air inlet pipe 60, thus avoiding the situation of liquid being sucked in when the deaerator is built into the steam generating chamber 1.

[0087] In this embodiment, the air inlet pipe 60 is set on the outer wall of the outer shell 4 of the steam generator, so as to avoid the air inlet pipe 60 occupying space in the steam generating chamber 1, reduce the volume of the steam generating chamber 1, and thus facilitate the miniaturization of the steam generator. Moreover, setting the air inlet pipe 60 on the outer wall of the outer shell 4 of the steam generator can simplify the piping system inside the steam generator and better achieve the miniaturization of the steam generator.

[0088] Furthermore, the air intake pipe 60 can continuously draw high-temperature water vapor from the steam generation chamber 1 into the first shell side 40 through the air extraction component 5, so that the liquid to be deoxygenated in the deoxygenation device is heated and deoxygenated more fully, so that the liquid to be deoxygenated can be quickly heated to saturation by high-temperature water vapor and oxygen can be fully released, thereby increasing the release rate of dissolved oxygen in the liquid to be deoxygenated and thus reducing the oxygen content in the liquid to be deoxygenated.

[0089] In other embodiments, such as Figure 1 and Figure 8 As shown, the top wall of the outer shell 4 is also provided with a steam outlet 6 communicating with the steam generating chamber 1, and a filter assembly 7 is adapted above the deaerator; and one end of the outer shell 4 along the axial direction is provided with a refrigerant outlet 8 and a refrigerant inlet 9 communicating with the heat exchange tube 2.
