Each deaerator unit is installed at intervals and interconnected on the top surface of the inlet pipe. The side cover is connected above the inlet pipe and covers the periphery of all deaerator units. Each deaerator unit includes a cap-shaped top cover and a connecting pipe located below the cap-shaped top cover.

Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and more particularly to a deaerator assembly, a steam generator, and an air conditioner. Background Technology

[0002] Shell-and-tube steam generators are widely used heat exchange devices in industry, primarily for heating water to produce steam. Their structure typically consists of a large shell and a bundle of tubes arranged inside. The working medium flowing within the tubes (such as refrigerant or superheated flue gas) exchanges heat with the water outside the tubes, thus achieving water vaporization. The origins of this device can be traced back to the Industrial Revolution; with the development of steam power technology, steam generators have gradually become an indispensable part of industrial production.

[0003] Shell-and-tube steam generators operate on the principle of heat conduction and convection. Their high efficiency and reliability have led to their widespread application in power plants, chemical plants, paper mills, food processing, and other fields. In recent years, with increasing demands for energy efficiency and environmental protection, the design and manufacturing technology of shell-and-tube steam generators have been continuously optimized to meet higher thermal efficiency and lower energy consumption requirements.

[0004] Currently, shell-and-tube heat exchangers are used as steam generators, but due to cost and technological limitations, their feed water generally contains dissolved oxygen. This dissolved oxygen continuously precipitates as the temperature rises, and if the concentration is too high, it can cause severe oxidation and corrosion to the shell and tube sheets, shell, and other structures, especially at welded joints, potentially leading to safety accidents. Existing shell-and-tube steam generators generally do not have deaerators, or if they do, they are usually based on deaerators used in boilers. However, boiler deaerators are typically external structures, bulky and unsuitable for internal installation in shell-and-tube steam generators. Furthermore, some types, such as water-spraying disc deaerators and spray-packed deaerators, require an external heat source, reducing system efficiency. Utility Model Content

[0005] This application provides a deaerator assembly, a steam generator, and an air conditioner to solve the technical problem that existing deaerators are generally external structures with large volumes, making them unsuitable for use in built-in shell-and-tube steam generators.

[0006] The deoxygenation assembly provided by this utility model includes: an inlet pipe, deoxygenation units, and a folded-edge cover plate. Multiple deoxygenation units are provided, each installed at intervals on the top surface of the inlet pipe and communicating with it. The folded-edge cover plate is connected above the inlet pipe and covers the periphery of all deoxygenation units. Each deoxygenation unit includes a cap-shaped top cover and a connecting pipe located below the cap-shaped top cover. Each deoxygenation unit is installed above the corresponding inlet pipe via the connecting pipe, and a liquid-retaining ring is installed near the outlet of the connecting pipe. As the main water flow flows upward through the inlet pipe into the deoxygenation unit, it is blocked by the liquid-retaining ring. Some water is jetted from one side of the connecting pipe, while the remaining water continues to flow upward and sprays into the lower surface of the cap-shaped top cover. After spreading on its surface, it forms a liquid film and falls downward. The falling water encounters the jet from one side of the connecting pipe, further breaking up the liquid film.

[0007] The connector has an opening on its side, and the liquid-retaining ring is located above the opening. Some water is jetted from the opening on the side of the connector, and the downward-falling water flow meets the jet from the opening on the side of the connector.

[0008] The liquid-retaining ring is connected to the cap-shaped top cover by multiple support rods; the top surface of each support rod extends out of the top surface outlet of the pipe and is connected to the inner top surface of the cap-shaped top cover.

[0009] The support rod has four rods, which are evenly distributed above the liquid-retaining ring.

[0010] The cap-shaped top cover is an arc-shaped top cover; the liquid-retaining ring is a hollow ring structure.

[0011] Each deaeration unit includes a guide rod, and there are multiple guide rods. The multiple guide rods are evenly distributed below the cap-shaped top cover. The multiple guide rods are arranged around the outer periphery of the pipe and the support rod. The guide rods are used to guide part of the water flow from the upward inflow direction to the downward outflow direction.

[0012] The guide rod includes a guide channel body and a guide surface connected to the top of the guide channel body. The guide channel body is used to guide part of the water flow upward along the guide channel, and the guide surface is used to guide part of the upward-flowing water flow to change to a downward-flowing direction.

[0013] The guide surface is constructed as a circular arc transition surface.

[0014] The deoxygenation assembly includes a support plate, and the water inlet pipe is horizontally arranged on the support plate. The deoxygenation unit is installed on the top of the water inlet pipe, and each deoxygenation unit is connected to the water inlet pipe. A gap is left between the lower edge of the folded cover plate and the pipe wall of the water inlet pipe so that a semi-enclosed space structure is formed between the folded cover plate, the upper pipe wall of the water inlet pipe, the connecting pipe and the cap-shaped top cover.

[0015] The lower edge of the folded cover plate is constructed as a beveled fold, and a gap is left between the beveled fold and the wall of the water inlet pipe.

[0016] This utility model also provides a steam generator, which includes a housing and the aforementioned deoxygenation assembly. The steam generator includes a left tube plate and a right tube plate installed on both sides of the housing. A left water chamber assembly is installed on the outside of one side of the left tube plate, and a tube box assembly with an air inlet pipe and a liquid outlet pipe is installed on the outside of one side of the right tube plate. An exhaust pipe is provided at the top of the housing. A baffle plate and a filter assembly located below the baffle plate are provided between the exhaust pipe and the housing. The deoxygenation assembly is located between the filter assembly and the heat exchange tube bundle. A support plate assembly is installed on the heat exchange tube bundle, and the deoxygenation assembly is installed inside the housing through the support plate assembly.

[0017] This utility model also provides an air conditioner, including the steam generator described above.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] The deaerator assembly, steam generator, and air conditioner provided in this application embodiment have a compact overall structure and occupy little space. During actual operation, within each deaerator unit, the main water flow (containing dissolved oxygen) is blocked by a baffle ring as it flows upwards, with some water jetting from one side of the connecting pipe. The remaining water continues to flow upwards and sprays into the lower surface of the cap-shaped top cover, spreading out to form a liquid film before falling downwards. After a period of time, the falling water meets the jet from one side of the connecting pipe, further breaking up the liquid film. Through this process, the water flow becomes a broken liquid film, greatly increasing the water contact area. Simultaneously, based on the principle of thermal deaeration, the steam generated by the boiling of water in the bottom heat exchanger tube area enters the rectangular space above the folded cover plate and the semi-enclosed space structure formed between the lower fold and the upper part of the inlet pipe, contacting the broken liquid film. The broken liquid film rapidly heats up, releasing the solvent oxygen. The separated dissolved oxygen overflows from the lower opening of the semi-enclosed space and is discharged from the exhaust port, reducing the contact and corrosion between oxygen and heat exchanger components, especially at weld seams. The dissolved oxygen water that has been separated is collected into a stream by the folding action of the folded edge of the cover plate and then flows into the full liquid area to evaporate, which helps to reduce the liquid carry-over problem caused by the direct flow of the broken liquid film.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptions used in this text have been explained accordingly.

[0033] The deoxygenation component provided by this utility model occupies a small space due to its overall structure, which facilitates the thermal deoxygenation of dissolved oxygen liquids inside large equipment. It can be applied to any application scenario that requires thermal deoxygenation. The specific structure of this utility model will be described in detail below, taking the application of the deoxygenation component in a condenser as an example.

[0034] Existing condensers are generally classified into air-cooled condensers and water-cooled condensers. The working principle of an air-cooled condenser is as follows: the refrigerant releases heat and condenses into a liquid state within the heat exchange tube bundle. As airflow passes over the outside of the heat exchange tube bundle, it absorbs heat and its temperature rises. A water-cooled condenser, on the other hand, utilizes the liquid outside the heat exchange tube bundle to absorb heat, causing it to vaporize into steam. Specifically, in a water-cooled condenser, the liquid submerged outside the heat exchange tube bundle absorbs the heat released by the refrigerant during condensation. As the deoxygenated liquid absorbs heat and its temperature rises, it evaporates into a gaseous state when the temperature exceeds the saturation temperature at the current pressure, producing high-temperature water vapor. This process causes the liquid level in the water-cooled condenser to gradually decrease. Therefore, it is necessary to replenish the liquid in the water-cooled condenser to ensure that the liquid in the shell side continuously absorbs heat from the heat exchange tube bundle, thus ensuring the basic function of the condenser.

[0035] When condensers require makeup liquid, the makeup liquid is typically a liquid containing dissolved oxygen. Excessive dissolved oxygen in the makeup liquid can cause severe oxidation and corrosion of the condenser shell and tube materials, potentially leading to serious accidents. In steam generating units, areas prone to oxidation and corrosion include the connections between the heat exchanger tube bundle and the support plate / tube sheet. These locations have high metal wall temperatures, intense water flow turbulence, and numerous assembly or welding gaps. In boiler systems, there are many methods for removing dissolved oxygen from feedwater, such as thermal deoxygenation, vacuum deoxygenation, chemical deoxygenation, and rust deoxygenation. Thermal deoxygenation is based on the Henry Dalton theorem, using a portion of the produced steam to heat the feedwater to saturation. At this point, the solubility of oxygen in the water is zero, and the oxygen is released and discharged. The water treated with thermal deoxygenation can then be used to supply steam to the boiler.

[0036] Existing deaerator components are large in size and take up a lot of space, so they can only be installed separately outside the condenser. Installing a separate thermal deaerator would increase system costs and equipment installation space.

[0037] To alleviate the above problems, this utility model provides an oxygen removal component with a small structural size, convenient installation, and the ability to be installed in existing large, medium, or small liquid storage equipment. Taking a steam generator as an example, the steam generator device is used to produce high-temperature steam.

[0038] For example, steam generators can be used in industries such as food processing, textile printing and dyeing, pharmaceuticals, chemicals, papermaking, heating systems, power generation, cleaning and disinfection, agricultural humidification, and car detailing. In the food processing industry, steam generators can be used for heating, sterilization, and cooking processes to ensure food safety and quality. In the textile industry, steam is used for pretreatment, dyeing, and setting of fabrics to improve their quality and feel. In pharmaceutical processes, steam is used for sterilization, drying, and extraction to ensure a sterile environment and product quality in drug production. In the chemical industry, steam acts as a heat source or reaction medium, participating in chemical reactions and promoting the mixing and transformation of materials. In the papermaking industry, steam is used for cooking, bleaching, and drying of raw materials to improve the physical properties of paper. In heating systems, especially in winter heating systems, steam is piped to various rooms to provide warmth to buildings. In power generation: thermal power plants use high-temperature, high-pressure steam generated from coal combustion to drive turbines to generate electricity. In cleaning and disinfection, medical equipment and tableware require regular high-temperature steam sterilization to kill bacteria and viruses. In agricultural humidification, steam is used in greenhouses to increase air humidity and improve the plant growing environment. In car detailing, steam is used to clean vehicle surfaces, removing stains without damaging the paint.

[0039] Furthermore, the specific structural composition of a steam generator heat pump unit is similar to that of a conventional air conditioning unit, consisting of four main components: a compressor, an evaporator, a throttling device, and a condenser. The high-temperature steam generated by the compressor enters the tube side of the condenser (e.g., high-temperature refrigerant vapor). The high-temperature refrigerant vapor in the evaporator's tube side heats the demineralized water in the shell side to produce high-temperature water vapor. The throttling device reduces the pressure of the liquid refrigerant condensed in the condenser's tube side. Afterward, the refrigerant, after pressure reduction, absorbs heat and evaporates into a low-temperature, low-pressure gaseous state in the evaporator, and then enters the compressor's suction port. Other supporting equipment includes water pumps, electrical systems, filters, etc.

[0040] For example, there are many types of steam generators, such as those that produce steam by heating water with electricity or by burning gas or oil.

[0041] For example, taking the application of the deoxygenation component in an evaporative condenser as an example, the structure of the deoxygenation component of this utility model will be specifically described.

[0042] like Figures 1-5The diagram shows a deaerator assembly 1 and a steam generator 2 equipped with the deaerator assembly 1 provided by this utility model. The deaerator assembly 1 includes: an inlet pipe 11, deaerator units 12, and a folded cover plate 13. Multiple deaerator units 12 are provided, each spaced apart and installed on the top surface of the inlet pipe 11, and each deaerator unit 12 is connected to the inlet pipe 11. The folded cover plate 13 is connected above the inlet pipe 11 and covers the outer periphery of all the deaerator units 12. Each deaerator unit 12 includes a cap-shaped top cover 121 and a receiving port located below the cap-shaped top cover 121. Each deaerator unit 12 is installed above the corresponding inlet pipe 11 via the pipe 122. A liquid-blocking ring 123 is installed near the outlet of the pipe 122. As the main water flow flows upward through the inlet pipe 11 into the deaerator unit 12, it is blocked by the liquid-blocking ring 123. Some water is jetted from one side of the pipe 122, and the remaining water continues to flow upward and sprays into the lower surface of the cap-shaped top cover 121. After spreading on its surface, it forms a liquid film and falls downward. The falling water meets the jet from one side of the pipe 122, further breaking up the liquid film.

[0043] Thus, the overall structure of the deaeration assembly 1 is compact and occupies little space. During actual operation, within each deaeration unit 12, the main water flow (containing dissolved oxygen) is blocked upwards by the baffle ring 123, causing some of the water flow ( Figure 2 The transverse water flow is jetted from one side of the nozzle 122. The remaining water flow ( Figure 2 The upward-flowing water continues to flow upward and sprays into the lower surface of the cap-shaped top cover 121, where it spreads out to form a liquid film before falling downward. Figure 2 The downward flow of water in the middle. The downward flow of water ( Figure 2 The downward flow of water in the middle) after a period of time and the jet from one side of the pipe 122 ( Figure 2 (Middle transverse flow) meets ( Figure 2 The dashed circle area further breaks up the liquid film. Through this process, the water flow becomes a broken liquid film, greatly increasing the water contact area. Simultaneously, based on the principle of thermal deoxygenation, water vapor generated by boiling in the bottom heat exchanger area (…) Figure 2 The water vapor stream enters the rectangular space above the folded cover plate 13 and forms a semi-enclosed space between the lower fold and the upper part of the inlet pipe 11, and comes into contact with the broken liquid film. The broken liquid film rapidly heats up and precipitates solvent oxygen. The separated dissolved oxygen overflows from the lower opening of the semi-enclosed space and is discharged from the exhaust port, reducing the contact and corrosion between oxygen and heat exchanger components, especially welds. The separated dissolved oxygen water ( Figure 2The deoxygenated water flow is gathered into a stream under the folding action of the lower side of the folded cover plate 13 and then flows into the full liquid area for evaporation, which helps to reduce the liquid carry-over problem caused by the direct flow of the broken liquid film.

[0044] Considering one of the structural schemes of the deoxygenation component 1, the connecting pipe 122 has a side opening 1221, the liquid-blocking ring 123 is located above the opening 1221, some water is jetted from the side opening 1221 of the connecting pipe 122, and the downward water flow meets the jet from the side opening 1221 of the connecting pipe 122.

[0045] Specifically, the deoxygenation assembly 1 consists of an inlet pipe 11, multiple deoxygenation units 12 arranged at intervals and connected to the inlet pipe 11, and a folded cover plate 13 covering the deoxygenation units 12, forming a compact deoxygenation space layout. In a single deoxygenation unit 12, the connecting pipe 122, the opening 1221, the liquid-retaining ring 123, and the cap-shaped top cover 121 work together: after the main water flow (containing dissolved oxygen) enters the deoxygenation unit 12 through the inlet pipe 11, it is blocked by the liquid-retaining ring 123. Based on the principle of "obstructed flow splitting" in fluid mechanics, part of the water flow is jetted laterally due to the presence of the opening 1221; the remaining water flow continues upward, impacting the lower surface of the cap-shaped top cover 121. According to the "fluid collision and diffusion film formation" mechanism, it spreads into a liquid film on the surface of the top cover, and then "falls" due to gravity. When these two streams (the lateral jet and the falling liquid film) meet, they follow the "liquid-liquid collision and breakup" principle, making the liquid film even finer and greatly increasing the specific surface area of ​​the water. At the same time, combined with the core logic of thermal deoxygenation, the water vapor generated by the boiling of water in the bottom heat exchange tube area enters the semi-enclosed space formed by the folded cover plate 13 and the water inlet pipe 11 using the "gas-liquid mass and heat transfer" principle. It comes into contact with the broken liquid film, and the temperature difference causes the liquid film to heat up, so that the dissolved oxygen decreases as the solubility increases with the temperature, thus achieving "oxygen evolution" separation.

[0046] Based on this, the compact layout minimizes the space occupied by the deaerator component 1, making it suitable for the limited internal space of equipment such as the steam generator 2, and facilitating the miniaturization and integration of the overall equipment design. Firstly, the broken liquid film significantly increases the contact area between water and steam, and combined with thermal deaeration, accelerates dissolved oxygen release, improving deaeration efficiency and effectiveness, resulting in a significant reduction in the oxygen content of the treated water. Secondly, dissolved oxygen is separated and discharged through a specific path, reducing its contact with heat exchanger components (especially easily corroded areas such as welds). Based on the principle of "oxygen deficiency slows corrosion," this delays equipment corrosion, extends the service life of the steam generator 2, and reduces maintenance costs. Furthermore, the deaerated water flows through the folded cover plate 13 and enters the full liquid zone for further evaporation, avoiding the chaotic liquid flow caused by the broken liquid film, ensuring stable steam-water circulation in the steam generator 2, improving steam quality, and ensuring efficient and reliable operation of the equipment. From structural design to functional implementation, the deaeration and overall operation performance of the steam generator 2 are optimized from multiple dimensions.

[0047] Considering one of the connection schemes between the liquid-retaining ring 123 and the cap-shaped top cover 121 and one of the structural schemes of the deoxygenation assembly 1, in the deoxygenation assembly 1 provided in this application embodiment, a plurality of support rods 124 are connected between the liquid-retaining ring 123 and the cap-shaped top cover 121; the top surface of each support rod 124 extends out of the top surface outlet of the connecting pipe 122 and is connected to the inner top surface of the cap-shaped top cover 121.

[0048] Thus, within the deaeration unit 12, the baffle ring 123 serves to divert and guide the water flow, while the cap-shaped top cover 121 facilitates the diffusion and film formation of the water flow. These two components are connected by multiple support rods 124, with the tops of the support rods 124 extending from the outlet of the connector 122 and connecting to the inner top of the cap-shaped top cover 121, forming a stable spatial support structure. Furthermore, the water flow is diverted by the baffle ring 123, with the lateral jet and the upward impacting water flow moving within the space formed by the support rods 124. The support rods 124 can disturb the flow pattern of the water flow (especially the water flow falling after impacting the top cover and the lateral jet flow), but due to their reasonable layout (multiple spaced distributions), they do not excessively hinder the process of water flow encountering and breaking up. Instead, the structural support ensures the stability of the cap-shaped top cover 121, making the path of the water flow impacting the top cover to form a film and falling more stable. Meanwhile, based on the thermal deoxygenation environment, the support rod 124, as a metal structure (most likely the same material as other components), can participate in heat transfer, assist in the heat exchange between the broken liquid film and water vapor, and promote the release of dissolved oxygen.

[0049] Specifically, the support rod 124 connects the liquid-retaining ring 123 and the cap-shaped top cover 121, enhancing the overall structural strength of the deoxygenation unit 12. This prevents displacement or deformation of the liquid-retaining ring 123 or the cap-shaped top cover 121 after long-term water flow impact, ensuring a stable deoxygenation process and improving component reliability and service life. Simultaneously, the stable position of the cap-shaped top cover 121 allows for more regular water flow impact film formation and cascading, making the encounter and collision with lateral jets more controllable. This facilitates consistent liquid film breakage, ensuring a stable increase in water contact area and improving deoxygenation uniformity and efficiency. Furthermore, the support rod 124 assists in heat exchange, accelerating the heating and oxygen evolution of the broken liquid film, enhancing the thermal deoxygenation effect, and allowing for more complete dissolved oxygen separation, further reducing the oxygen content of the water flow. From the perspective of the overall operation of the deoxygenation component 1, this connection scheme, through structural reinforcement and process optimization, helps improve deoxygenation performance, ensuring the stability and efficiency of the deoxygenation process in the steam generator 2, indirectly improving steam quality and equipment operational reliability. This synergistic optimization from structure to function strengthens the technological advantages of the deoxygenation component 1.

[0050] Considering the specific arrangement of the support rod 124, in the deoxygenation assembly 1 provided in this application embodiment, there are four support rods 124, and the four support rods 124 are evenly distributed above the liquid-blocking ring 123.

[0051] In this way, four support rods 124 evenly distributed above the baffle ring 123 are set up, utilizing the geometric stability of quadrilaterals to construct a symmetrical and balanced support structure. The four support rods 124 evenly distribute the load of the cap-shaped top cover 121 to the baffle ring 123, avoiding local stress concentration and ensuring that the deaerator unit 12 remains structurally stable under long-term water flow impact and thermal expansion and contraction caused by heat exchange, and that the relative positions of the cap-shaped top cover 121 and the baffle ring 123 do not shift. Furthermore, the four evenly distributed support rods 124 form regular flow channel intervals inside the deaerator unit 12. After the main water flow is diverted by the baffle ring 123, the lateral jet (ejected through the opening 1221 of the pipe 122) and the water flow impacting the cap-shaped top cover 121 upwards flow within the space between the support rods 124. Due to the symmetrical layout, the jet direction, film formation range, and fall path of the water flow are more uniformly disturbed. This design ensures that the lateral jet and the falling liquid film meet and break up in an orderly manner, while avoiding water flow concentration and turbulence caused by structural asymmetry. This maintains the stability of the "jet-film formation-breakup" deoxygenation process, providing a fluid motion basis for efficient deoxygenation. Furthermore, the four support rods 124, as metal structures (compatible with other metal components of the assembly), participate in heat transfer. Their uniform distribution facilitates uniform heat exchange between the broken liquid film and water vapor within the deoxygenation unit 12. By increasing the temperature and reducing dissolved oxygen solubility, dissolved oxygen is promoted to be released from the water, enhancing the physicochemical process of thermal deoxygenation.

[0052] Specifically, the four evenly distributed support rods 124 significantly improve the deformation resistance of the deoxygenation unit 12 by symmetrically distributing the load. Whether it is the thermal stress during startup and shutdown or the continuous water flow impact during operation, they can ensure the stability of key components such as the cap-shaped top cover 121 and the liquid baffle ring 123, reduce the fluctuation of deoxygenation effect caused by structural deformation, extend the service life of the components, and reduce equipment maintenance costs.

[0053] Considering the specific construction schemes of the cap-shaped top cover 121 and the liquid-retaining ring 123, in the deoxygenation assembly 1 provided in this application embodiment, the cap-shaped top cover 121 is constructed as an arc-shaped top cover; the liquid-retaining ring 123 is constructed as a ring structure with a hollow center.

[0054] Thus, the cap-shaped top cover 121 is constructed as an arc-shaped top cover, following the optimization logic of "fluid collision with wall diffusion to form a film": when the water flow impacts the lower surface of the arc-shaped top cover upwards, the smooth transition characteristics of the arc surface can guide the water flow to spread more evenly in all directions, avoiding the local accumulation of water flow that is prone to occur with right-angle or acute-angle top covers, providing a structural basis for the formation of a complete and uniformly thick liquid film. The liquid-blocking ring 123 is constructed as a hollow ring structure in the middle. Based on the precise control requirements of fluid diversion, the hollow structure not only reserves a channel for part of the water flow to continue to flow upwards, but also effectively blocks the water flow through the ring edge, forcing another part of the water flow to jet from the side of the nozzle 122 to the opening 1221, realizing the stable diversion of the main water flow, and the ring structure can make the water flow uniformly stressed in the circumference, ensuring the symmetry and consistency of the lateral jet.

[0055] Furthermore, the arc-shaped top cover reduces local resistance loss during water flow impact, lowering energy consumption while making liquid film formation more stable and reducing uneven liquid film rupture caused by unreasonable top cover shape. The symmetrical structure of the annular liquid-retaining ring 123 ensures the stability of the flow distribution ratio, making the distribution of lateral jets and upward water flow more uniform and improving the consistency of operation of the deaerator unit 12. In addition, after the uniform liquid film forms under the arc-shaped top cover, it falls and collides more fully with the symmetrical lateral jets guided by the annular liquid-retaining ring 123, resulting in more uniform liquid film breakage and increasing the contact area between water and steam. At the same time, the synergistic effect of the arc-shaped top cover and the annular liquid-retaining ring 123 makes the thermal deaerator process more stable, promotes more complete release of dissolved oxygen, further reduces the oxygen content of the water flow, and improves the operational reliability of the steam generator 2.

[0056] Considering another scheme for the deoxygenation unit 12, in the deoxygenation assembly 1 provided in this application embodiment, each deoxygenation unit 12 includes a guide rod 125. There are multiple guide rods 125, which are evenly distributed below the cap-shaped top cover 121. The multiple guide rods 125 are arranged around the outer periphery of the pipe 122 and the support rod 124. The guide rods 125 are used to guide part of the water flow from the upward inflow direction to the downward outflow direction.

[0057] Thus, multiple guide rods 125, evenly distributed below the cap-shaped top cover 121 and surrounding the nozzle 122 and support rod 124, function based on the principle of fluid motion guidance. When water flows through the lower surface of the cap-shaped top cover 121, diffuses into a liquid film, and falls downwards, and when some water flows from the nozzle 122 side toward the opening 1221, the guide rods 125 constrain the flow path through their spatial arrangement. For the portion of water flowing upwards to the vicinity of the cap-shaped top cover 121, the guide rods 125 utilize their columnar structure to generate obstruction and guidance force on the water flow. Based on the laws of fluid flow around and turning, they forcibly change the original upward direction of the water flow to downwards, forming a flow trend in the same direction or intersecting with the naturally falling liquid film, enhancing the disturbance and mixing of the water flow within the deaeration unit 12. At the same time, the evenly distributed layout ensures that the water flow is uniformly guided in the circumferential direction, avoiding local water flow turbulence or dead zones.

[0058] Specifically, the guide rod 125 effectively regulates the water flow direction, redirecting some upward water flow to downward flow. This creates a more orderly circulating flow within the deaeration unit 12, reducing energy loss caused by direct impact of water flow on the inner wall of the component. It also increases the probability of contact between the downward-falling liquid film and other water flows. Furthermore, the water flow guided and redirected by the guide rod 125 further interweaves and collides with the existing falling liquid film and lateral jets, promoting more thorough film breakup and increasing the contact area between water and steam. The evenly distributed guide rods 125 ensure consistent water flow redirection, improving the uniformity of deaeration in all areas of the deaeration unit 12, reducing the problem of locally high oxygen content, and thus enhancing the overall deaeration stability and efficiency of the steam generator 2.

[0059] Considering the specific construction scheme of the guide rod 125, in the deaeration assembly 1 provided in this application embodiment, the guide rod 125 includes a guide channel body 1251 and a guide surface 1252 connected to the top of the guide channel body 1251. The guide channel body 1251 is used to guide part of the water flow upward along the guide channel, and the guide surface 1252 is used to guide the upward-flowing part of the water flow to change to a downward-flowing direction.

[0060] In this way, the guide channel body 1251 and guide surface 1252 of the guide rod 125 work together to achieve precise water flow guidance based on the fluid flow characteristics along the wall. The guide channel body 1251 forms a directional channel through its own channel structure. According to the principle of "fluid flowing towards the channel", some water flows steadily upward along the channel, avoiding disorderly diffusion of water within the unit. When the water flows upward through the guide channel body 1251 to the top, the guide surface 1252 plays a deflecting role. Its inclined or arc-shaped surface structure uses the "fluid hitting the wall and deflecting" mechanism to smoothly guide the originally upward water flow direction to downward. Compared with a simple columnar guide rod 125, it reduces energy loss and turbulence interference when the water flow changes direction, ensuring more efficient and stable water flow direction changes.

[0061] Specifically, the main body 1251 of the guide channel ensures the directionality of the upward water flow, avoiding energy waste caused by water flow dispersion; the smooth turning design of the guide surface 1252 makes the water flow direction change smoother, reduces the generation of local eddies, and makes the collision of the downward flowing water with the falling liquid film and the lateral jet more orderly. In addition, the directional water flow has more sufficient contact with other water flows after turning, the liquid film breaking effect is more uniform, and the contact area between water and steam is further increased; at the same time, it reduces the local deoxygenation dead zones caused by water flow turbulence, improves the overall deoxygenation efficiency of the deoxygenation unit 12, and provides a more reliable water quality guarantee for the stable operation of the steam generator 2.

[0062] Considering the specific construction scheme of the guide surface 1252, in the deoxygenation component 1 provided in this application embodiment, the guide surface 1252 is constructed as an arc transition surface.

[0063] In this way, the principle of "smooth wall drag reduction" in fluid dynamics comes into play. The arc transition surface has a continuously changing curvature. When water flows upward through the guide channel body 1251 to the guide surface 1252, the water flows along the arc surface, avoiding the local eddies and impact losses that are easily generated by right-angle or acute-angle guide surfaces 1252. Its curvature design is adapted to the water flow velocity characteristics, and through the synergistic effect of wall friction and pressure gradient, the kinetic energy of the upward water flow is smoothly converted into the kinetic energy of the downward flow, realizing the impact-free turning of the water flow direction, ensuring the stability of the water flow state during the turning process, and reducing energy loss.

[0064] Specifically, the continuous curvature of the arc transition surface makes the water flow more gentle, significantly reducing local resistance and turbulence during the turning process. This ensures that the downward-flowing water has a stable velocity and direction, and the collisions with the falling liquid film and lateral jets are more uniform and controllable. In addition, the stable turning water flow improves the contact efficiency with other water flows, resulting in more complete and consistent liquid film breaking, and increasing the effective contact area between water and steam. At the same time, it reduces the deoxygenation dead zones caused by turning turbulence, further improving the deoxygenation efficiency and stability of the deoxygenation unit 12, providing strong support for the reliable operation of the steam generator 2.

[0065] Considering the installation scheme of the deoxygenation component 1 in the specific application scenario, the deoxygenation component 1 provided in this application embodiment includes a support plate 126, and the water inlet pipe 11 is horizontally arranged on the support plate 126; the deoxygenation unit 12 is installed on the top of the water inlet pipe 11, and each deoxygenation unit 12 is connected to the water inlet pipe 11. A gap 132 is left between the lower edge 131 of the folded cover plate 13 and the pipe wall of the water inlet pipe 11, so that a semi-closed space structure is formed between the folded cover plate 13, the upper pipe wall of the water inlet pipe 11, the connecting pipe 122 and the cap-shaped top cover 121.

[0066] In this way, the support plate 126 provides a stable installation foundation for the deaerator assembly 1. The inlet pipe 11 is horizontally mounted on the support plate 126. With the support plate 126's load-bearing capacity, the inlet pipe 11 and the deaerator unit 12, the folded cover plate 13, and other components above it are reliably fixed, ensuring that the assembly maintains structural stability under water flow impact and equipment vibration. The lower edge 131 of the folded cover plate 13 leaves a gap 132 between itself and the wall of the inlet pipe 11. Combined with the enclosure effect of the upper wall of the inlet pipe 11, the connecting pipe 122, and the cap-shaped top cover 121, a semi-enclosed space structure is formed. This structure allows the water vapor generated by the bottom heat exchange tube to effectively accumulate and fully contact the broken liquid film, and also provides a discharge channel for the separated dissolved oxygen through the gap 132, realizing the synergistic function of steam retention mass transfer and directional oxygen discharge.

[0067] Specifically, the support plate 126 enhances the overall structural rigidity of the deaerator assembly 1, reducing component swaying or displacement caused by water flow impact during operation, minimizing fatigue wear at connection points, and extending the assembly's service life. Furthermore, the semi-enclosed space structure allows for efficient steam circulation within a limited area, increasing the contact time and area with the broken liquid film, thus strengthening the thermal deaeration effect. Simultaneously, the reasonable spacing 132 ensures smooth discharge of dissolved oxygen, reducing oxygen retention and secondary dissolution within the space, further reducing the oxygen content of the water flow, and guaranteeing the corrosion resistance and operational reliability of the heat exchange components of the steam generator 2.

[0068] Considering the specific construction scheme of the semi-enclosed space structure of the folded cover plate 13 relative to the upper pipe wall of the water inlet pipe 11, the connecting pipe 122 and the cap-shaped top cover 121, in the deoxygenation assembly 1 provided in this application embodiment, the lower edge 131 of the folded cover plate 13 is constructed as a beveled edge, and the gap 132 is left between the beveled edge and the pipe wall of the water inlet pipe 11.

[0069] Thus, based on the synergistic principle of fluid guidance and spatial sealing, the gap 132 formed by the inclined flange and the wall of the inlet pipe 11 has a directional guiding effect. The inclined structure can use its own tilt angle to block the upward flow of steam, slowing down the direct escape rate of steam, prolonging the residence time of steam in the semi-enclosed space, and ensuring that the steam and the broken liquid film are in full contact for heat and mass exchange. At the same time, the inclined flange guides the separated dissolved oxygen to flow orderly along the gap 132 below the inclined surface, avoiding oxygen accumulation or obstruction of discharge caused by the right-angle flange, and achieving a balance between efficient steam utilization and directional oxygen discharge.

[0070] Specifically, the beveled edge optimizes the airflow path in the semi-enclosed space, reduces steam short-circuiting and escape, improves the contact efficiency between steam and the broken liquid film, enhances the thermal deoxygenation effect, and allows for more complete dissolved oxygen release. Furthermore, the beveled edge makes the airflow at gap 132 smoother, reduces oxygen discharge resistance, and minimizes the risk of secondary oxygen dissolution in the semi-enclosed space. Simultaneously, the beveled structure acts as a buffer and guide for the falling deoxygenated water flow, assisting the water flow to converge into a stream under the beveled cover plate 13, further reducing liquid carryover and improving the stability and reliability of the deoxygenation assembly 1.

[0071] This application embodiment also provides a steam generator 2, which includes a housing 21 and the aforementioned deaerator assembly 1. The steam generator 2 includes a left tube plate 22 and a right tube plate 23 installed on both sides of the housing 21. A left water chamber assembly 24 is installed on the outside of one side of the left tube plate 22, and a tube box assembly 25 with an air inlet pipe 251 and a liquid outlet pipe 252 is installed on the outside of one side of the right tube plate 23. The top of the housing 21 has an exhaust pipe 253. A baffle plate 26 and a filter screen assembly 27 located below the baffle plate 26 are provided between the exhaust pipe 253 and the housing 21. The deaerator assembly 1 is located between the filter screen assembly 27 and the heat exchange tube bundle 28. A support plate assembly 29 is installed on the heat exchange tube bundle 28, and the deaerator assembly 1 is installed inside the housing 21 through the support plate assembly 29. This can achieve all the effects of the aforementioned deaerator assembly 1, which will not be elaborated further here.

[0072] This application embodiment provides another air conditioner, including the steam generator described above, which can achieve all the effects of the aforementioned deoxygenation component 1, and will not be described in detail here.

[0073] To better understand the deaerator assembly 1 and the steam generator 2 having the deaerator assembly 1 provided in the embodiments of this application, the following embodiments are provided for further explanation:

[0074] The steam generator 2 provided in this embodiment is a shell-and-tube steam generator 2. This shell-and-tube steam generator 2 has a built-in deaerator assembly 1, which is a composite structure composed of a folded cover plate 13, a deaerator unit 12, a water inlet pipe 11, a support plate 126, and the deaerator unit 12. The support plate 126 is located below the water inlet pipe 11 and is welded to the support plate assembly 29. The folded cover plate 13 is located above the water inlet pipe 11, and its upper rectangular space and lower folded edge form a semi-enclosed space structure with the upper part of the water inlet pipe 11. Multiple deaerator units 12 are installed on the corresponding circular holes above the water inlet pipe 11. The liquid-retaining ring 123 of the deaerator unit 12 is installed near the outlet of the connecting pipe 122. Four support rods 124 are symmetrically installed on the upper surface of the liquid-retaining ring 123, and the support rods 124 extend a certain distance from the outlet of the connecting pipe 122, with their upper ends connected to a cap-shaped top cover 121. The connecting pipe 122 on the lower side of the baffle ring 123 has a circular hole facing upwards. All parts of the aforementioned deaeration assembly 1 are made of stainless steel. During actual operation, within each deaeration unit 12, the water flow ( Figure 2 As the main water flow (including dissolved oxygen) moves upward, it is blocked by the liquid-retaining ring 123, and some of the water ( Figure 2 The transverse water flow is jetted from the nozzle 122 to the opening 1221. Residual water ( Figure 2 The upward-flowing water continues to flow upward and sprays into the lower surface of the cap-shaped top cover 121, where it spreads out to form a liquid film before falling downward. Figure 2 The downward flow of water in the middle. The downward flow of water ( Figure 2 The downward water flow in the middle) after a period of time and the jet from the lateral opening 1221 of the pipe 122 ( Figure 2 (Middle transverse flow) meets ( Figure 2 The dashed circle area further breaks up the liquid film. Through this process, the water flow becomes a broken liquid film, greatly increasing the water contact area. Simultaneously, based on the principle of thermal deoxygenation, water vapor generated by boiling in the bottom heat exchanger area (…) Figure 2 The water vapor stream enters the rectangular space above the folded cover plate 13 and forms a semi-enclosed space between the lower fold and the upper part of the inlet pipe 11, and comes into contact with the broken liquid film. The broken liquid film rapidly heats up and precipitates solvent oxygen. The separated dissolved oxygen overflows from the lower opening of the semi-enclosed space and is discharged from the exhaust port, reducing the contact and corrosion between oxygen and heat exchanger components, especially welds. The separated dissolved oxygen water ( Figure 2 The deoxygenated water flow is gathered into a stream under the folding action of the lower side of the folded cover plate 13 and then flows into the full liquid area for evaporation, which helps to reduce the liquid carry-over problem caused by the direct flow of the broken liquid film.

[0075] In addition, this application embodiment also provides a shell-and-tube steam generator 2 with a built-in deaerator assembly 1, wherein the built-in deaerator assembly 1 is a composite structure composed of a folded cover plate 13, a deaerator unit 12, a water inlet pipe 11, a support plate 126, and the deaerator unit 12. The support plate 126 is located below the water inlet pipe 11 and is welded to the support plate assembly 29. The folded cover plate 13 is located above the water inlet pipe 11, and the rectangular space above it and the lower folded edge form a semi-enclosed space structure between it and the upper part of the water inlet pipe 11. Multiple deaerator units 12 are installed on the corresponding circular holes above the water inlet pipe 11. A baffle ring 123 is installed near the outlet of the connector 122. Four support rods 124 are symmetrically mounted on the upper surface of the baffle ring 123. The support rods 124 extend a certain distance from the outlet of the connector 122, and their upper ends are connected to a cap-shaped top cover 121. Multiple arrays of guide rods 125 are provided on the bottom circumference of the cap-shaped top cover 121. The connection between the guide rods 125 and the cap-shaped top cover 121 is a rounded transition. A guide groove structure is provided from top to bottom on the side facing the connector 122. A ring-shaped hole is opened circumferentially upwards on the connector 122 below the baffle ring 123. All parts of the aforementioned deaeration assembly 1 are made of stainless steel. In actual operation, within each deaeration unit 12, the water flow ( Figure 3 During the upward flow of the main water flow (including dissolved oxygen), some water ( Figure 3 The transverse water flow (from the inlet pipe 122) flows out through the annular orifice, forming a film jet. Residual water ( Figure 3 The upward-flowing water continues to flow upwards and is sprayed into the lower surface of the cap-shaped top cover 121, where it spreads out. Part of the spreading water is blocked by the guide rod 125, and due to its arc-shaped guide structure and guide groove, it forms droplets that drip downwards. Figure 3 The water flows downwards (1); another part of the diffused water flows through the gap 132 between the guide channels and continues to diffuse into a thinner liquid film before falling downwards ( Figure 3 Another downward-flowing stream 1). During their descent, the droplets and liquid film collide with the film jet formed by the outflow from the annular orifice, further breaking up the liquid film and droplets. Figure 3(The area indicated by the dashed circle). (The guide rod 125 and the gap 132 between them split the water flow into two parts. One part is guided downward through the guide groove on the guide rod 125, and the other part continues to fall from the edge of the cap-shaped top cover 121. The two then collide with the film jet flowing out from the annular hole on the side of the pipe 122. This structure increases the frequency of fluid collisions compared to the previous example, and its fluid breaking effect is better than the previous embodiment). After the above process, the water flow becomes a broken liquid film, which greatly increases the water contact area. At the same time, based on the principle of thermal deoxygenation, the water vapor generated by the boiling of water in the bottom heat exchange tube area enters the rectangular space above the folded cover plate 13 and the semi-enclosed space structure formed between the lower fold and the upper part of the water inlet pipe 11, and comes into contact with the broken liquid film. The broken liquid film heats up rapidly and precipitates the solvent oxygen in it. The separated dissolved oxygen overflows from the lower opening of the semi-enclosed space and is discharged from the exhaust port, reducing the contact and corrosion of oxygen with heat exchanger components, especially welds. The dissolved oxygen water that has been separated is collected into a stream by the folding action of the lower side of the folded cover plate 13 and then flows into the full liquid area for evaporation, which helps to reduce the liquid carry-over problem caused by the direct outflow of the broken liquid film.

[0076] The principle of thermal deoxygenation applied is as follows: According to the Henry Dalton theorem, the closer water is to saturation, the lower the dissolved oxygen content. When water is heated to saturation, the vapor pressure at the water surface approaches the total pressure at the water surface, and the partial pressure of dissolved oxygen in the water approaches zero. This causes the water to lose its ability to dissolve gases, and the dissolved gases will precipitate out. The precipitated oxygen needs to overcome surface energy and simultaneously pass through the gas-liquid interface into the vapor.
