[0002] This disclosure is based on and claims priority to Chinese application No. 202411925917.2, filed on December 25, 2024, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure relates to the field of steam generators with thermal deoxygenation function, and more particularly to a deoxygenation component and an evaporative condenser. Background Technology

[0004] Horizontal tube flooded evaporators, as traditional large-capacity evaporators, are widely used in air conditioning, heat pump heating, chemical and other fields due to their low cost and high stability. During operation, the liquid to be evaporated fills the shell-side space outside the heat exchange tubes (the liquid level is usually slightly higher than the highest point of the heat exchange tube bank). The heat released by the fluid inside the tubes is conducted to the liquid outside the tubes through the tube walls and fins, causing a phase change in the liquid. The gas generated by boiling heat exchange is discharged from the top of the heat exchanger.

[0005] If a horizontal tube evaporator is used as a steam generator, the shell-side space outside the heat exchange tubes contains boiling water, while the inside of the tubes contains other heat transfer fluids. The water is heated through the heat exchange tubes to become high-temperature steam. In high-temperature steam heat pump units, the steam generator is the device that directly produces steam, and its durability is closely related to the water quality inside the shell. If the dissolved oxygen content in the makeup water is too high, it will cause severe oxidation and corrosion of the shell and tube materials, and may even lead to serious accidents. The areas in the steam generator prone to oxidation and corrosion are the connections between the heat exchange tube bundle and the support plate / tube sheet, where the metal wall temperature is high, the water flow is turbulent, and there are many 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. The principle of 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 from the water. The deoxygenated water is then supplied to the boiler to generate steam.

[0006] A horizontal tube evaporator filled with liquid serves as a steam generator, and part of the produced steam can be used to heat the feedwater. If a separate thermal deaerator is installed, it will increase the system cost and equipment installation space. Summary of the Invention

[0007] This disclosure provides a deaerator assembly and an evaporative condenser to solve the technical problem in the above-mentioned related technologies that a horizontal tube full-liquid evaporator can be used as a steam generator, and part of the produced steam can be used to heat the feedwater. However, if a separate thermal deaerator is installed, it will increase the system cost and equipment installation space.

[0008] Some embodiments of this disclosure provide oxygen removal components, which include:

[0009] The heat-conducting container has an internal cavity. One side of the heat-conducting container has an inlet for the liquid to be deoxygenated to flow into the cavity. The heat-conducting container is configured to heat the liquid to be deoxygenated for the first deoxygenation. There are liquid flow channels and air flow channels between the cavity and the external environment. The air flow channel is configured to allow the released oxygen to flow out to the space above the external environment. The liquid flow channel is configured to allow the liquid to be deoxygenated to flow out to the bottom of the heat-conducting container for the second deoxygenation under the action of high-temperature air flow.

[0010] In some embodiments, the external environment is maintained in a region where a high-temperature airflow is flowing upwards.

[0011] In some embodiments, at least one side wall of the heat-conducting container has a plurality of air outlets, each air outlet being connected to a cavity to form a plurality of airflow channels.

[0012] In some embodiments, the liquid flow channel is configured to allow at least a portion of the liquid to be deoxygenated to drip downwards under its own weight, and to release oxygen below the heat-conducting container under the action of an upward-flowing high-temperature gas flow.

[0013] In some embodiments, the bottom wall of the heat-conducting container has multiple liquid distribution holes, each of which is connected to the cavity to form multiple liquid flow channels.

[0014] In some embodiments, the diameter of the equalization orifice ranges from 2 mm to 10 mm.

[0015] In some embodiments, the heat-conducting container is constructed as a box-shaped structure, with each wall of the box-shaped structure using a heat-conducting plate, and the heat-conducting container is configured to be located in the upstream region of the high-temperature airflow.

[0016] In some embodiments, the heat-conducting container includes a cover and a housing, the cover being detachably closed onto the opening of the housing.

[0017] In some embodiments, the heat-conducting container is constructed as a single-piece structure.

[0018] In some embodiments, the heat-conducting container is constructed as a detachable sheet metal structure.

[0019] Some embodiments of this disclosure provide an evaporative condensation apparatus, comprising:

[0020] The shell contains a lower region where a deoxygenated liquid is stored and a heat exchange tube bundle is installed, the heat exchange tube bundle being immersed in the deoxygenated liquid; the deoxygenated liquid vaporizes at a high temperature, forming an upward high-temperature gas flow; the upper region of the shell has a lateral space for the flow of the high-temperature gas flow; and

[0021] The oxygen removal component in the above embodiment is installed in the lateral space.

[0022] In some embodiments, the top of the housing is connected to an exhaust pipe. Along the height direction of the housing, the vertical projection of the deoxygenation component relative to the bottom surface of the housing is the first vertical projection area, and the vertical projection of the exhaust hole that is directly connected to the housing relative to the bottom surface of the housing is the second vertical projection area. The distance between the first vertical projection area and the second vertical projection area is the farthest line segment inside the housing.

[0023] In some embodiments, the evaporative condenser further includes a gas-liquid filter screen disposed inside the housing, which is laid horizontally above the deoxygenation assembly and below the gas outlet.

[0024] Compared with related technologies, the technical solutions provided in this disclosure have the following advantages:

[0025] The deoxygenation assembly and evaporative condenser provided in this disclosure utilize a heat-conducting container with inherent thermal conductivity. In a high-temperature environment, heat is conducted through the heat-conducting container, raising its own structural temperature. During application, the deoxygenating liquid flows into the cavity through an inlet on one side of the heat-conducting container. The liquid undergoes secondary heating inside the container, achieving the first deoxygenation. Oxygen is released inside the container, and this oxygen flows to the external environment through an airflow channel.

[0026] The deoxygenated liquid stored in the cavity at this time is the deoxygenated liquid after the first deoxygenation. Then, the deoxygenated liquid flows out through the liquid flow channel to the bottom of the heat-conducting container. Afterwards, the deoxygenated liquid undergoes a second deoxygenation under the action of high-temperature gas flow, and residual oxygen continues to be released below the heat-conducting container.

[0027] The deoxygenation component using the disclosed solution has a compact overall structure, occupies little space, and is easy to assemble. It can perform two deoxygenation processes on the liquid to be deoxygenated, making it easy to install in various equipment containers, especially suitable for deoxygenating makeup water. An evaporative condenser equipped with this deoxygenation component can use its own high-temperature steam as a high-temperature gas flow to provide a secondary heating environment for the heat-conducting container and perform a second deoxygenation on the liquid to be deoxygenated flowing out of the heat-conducting container; exemplarily, the liquid to be deoxygenated is makeup water. Furthermore, installing the deoxygenation component inside the existing horizontal tube evaporator structure can reduce system costs and external equipment installation space, while also preventing dissolved oxygen in the makeup water from oxidizing and corroding the internal structure.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of this disclosure. 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 this disclosure. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." 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.

[0041] The deoxygenation component provided in this disclosure 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 following is a detailed description of the specific structure of this disclosure, taking the application of the deoxygenation component in a condenser as an example.

[0042] Condensers used in related technologies are generally divided 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. Thus, the liquid level in the water-cooled condenser gradually decreases. Therefore, it is necessary to replenish the liquid in the water-cooled condenser to ensure that the liquid in the shell side of the condenser can continuously absorb heat from the heat exchange tube bundle, thereby ensuring the basic function of the condenser.

[0043] 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.

[0044] The deoxygenation components of related technologies are relatively large in size and occupy a lot of space. They can only be installed separately outside the condenser. If a separate thermal deoxygenation device is installed, it will increase the system cost and the installation space required.

[0045] To address the aforementioned problems, embodiments of this disclosure provide 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 devices. Taking a steam generator as an example, the steam generator device is used to produce high-temperature steam.

[0046] 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.

[0047] Furthermore, the specific structural composition of a steam generator heat pump unit is similar to that of a conventional air conditioning unit, including a compressor, evaporator, throttling device, and 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.

[0048] 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.

[0049] For example, taking the application of the deoxygenation component in an evaporative condenser as an example, the structure of the deoxygenation component of this disclosure will be specifically described.

[0050] The deoxygenating liquid disclosed herein can be demineralized water or a mixture of chemical substances. For example, demineralized water, also known as deionized water or pure water, refers to water from which most or all ions (such as sodium, calcium, magnesium, chlorine, etc.) have been removed through physical or chemical methods. Demineralized water is used to generate water vapor within the equipment. For example, the mixture of chemical substances has different boiling points; heating the medium yields low-boiling-point vapor, which allows for the separation of physical properties. This disclosure does not limit the composition of the deoxygenating liquid; the specific composition depends on the actual application scenario.

[0051] As shown in Figures 1-6, the present disclosure provides an oxygen desiccant assembly 1 and an evaporative condenser 2 equipped with the oxygen desiccant assembly 1. The oxygen desiccant assembly 1 includes a heat-conducting container 11 with an internal cavity 111. Exemplarily, the heat-conducting container 11 can be understood as a container made of a heat-conducting material. Based on this property, when the heat-conducting container 11 is placed in a high-temperature or low-temperature environment, the heat-conducting container 11 can conduct heat with the high-temperature or low-temperature environment, thereby maintaining the temperature balance between the heat-conducting container 11 and the ambient temperature. The heat-conducting container 11 of the present disclosure has a liquid inlet 112 on one side, which is connected to the cavity 111 of the heat-conducting container 11. The replenishing water (i.e., the liquid to be deoxygenated) flows into the cavity 111 through the liquid inlet 112. This disclosure does not limit the shape, size, or location of the inlet 112, as long as it ensures that the replenishing water flows from the inlet 112 into the cavity 111, and that the replenishing water in the cavity 111 does not flow out to the external environment through the inlet 112. For example, the inlet 112 can be any regular shape among square, circular, trapezoidal, or polygonal shapes, or it can be an irregular shape, depending on the actual application scenario.

[0052] The deoxygenation component 1 disclosed herein further includes a liquid flow channel and an air flow channel, both of which are formed between the cavity 111 and the external environment. For example, the liquid flow channel and the air flow channel can be understood as solid structural channels, such as channels with physical pipe connections; or they can be understood as functional channels, such as where replenishing water flows through the liquid flow channel from the cavity 111 of the heat-conducting container 11 to the external environment, without needing to define a fixed channel area using a physical structure.

[0053] Using the above structure, the makeup water, i.e., the deoxygenated liquid, flows into the cavity 111 through the inlet 112. Since the heat-conducting container 11 is placed in a high-heat environment, the temperature inside the cavity 111 is high through heat conduction. This can be understood as a heating process of the deoxygenated liquid within the heat-conducting container 11. This higher temperature heats the makeup water in the cavity 111 to a saturated state. At this saturated state, the solubility of oxygen in the makeup water is zero, and oxygen is released from the water, thus forming at least a portion of the deoxygenated liquid releasing oxygen within the cavity 111 of the heat-conducting container 11. Due to the continuous flow of gas, this portion of released oxygen flows to the external environment through the airflow channel, thereby achieving the first deoxygenation effect.

[0054] Furthermore, after the initial deoxygenation, the replenishing water in the inner cavity 111 of the heat-conducting container 11 flows out through the liquid flow channel to the bottom of the heat-conducting container 11, where it undergoes a second deoxygenation under the action of the high-temperature airflow. It should be noted that the external environment in this scheme is set to be located in the upstream region of the high-temperature airflow. This can be understood as the external environment being located in the region where the high-temperature airflow flows upward. In this way, a continuous flow of high-temperature airflow will act on the heat-conducting container 11, ensuring that the heat-conducting container 11 will always exchange heat with the heat source (i.e., the high-temperature airflow). This further ensures the necessary condition for the first deoxygenation, namely the thermal conductivity of the heat-conducting container 11. The temperature of the heat-conducting container 11 must be higher than the initial temperature of the replenishing water in the cavity 111. At the same time, the replenishing water flowing out through the liquid flow channel can also be heated by heat transfer in the high-temperature airflow, thereby reaching a saturated state. In this saturated state, the solubility of oxygen in the replenishing water is zero, and the residual oxygen is released again, thus achieving the effect of a second deoxygenation below the heat-conducting container 11.

[0055] In this embodiment, as shown in Figure 3, considering the actual water filling method in the heat-conducting container 11, the deoxygenation component 1 of this solution also includes a liquid inlet pipe 12. The liquid inlet pipe 12 includes an inlet and an outlet, with the inlet's horizontal position higher than the outlet's horizontal position. In actual installation scenarios, the liquid inlet pipe 12 communicates with the internal cavity 111 through the inlet 112 of the heat-conducting container 11; that is, the outlet extends into the cavity 111 of the heat-conducting container 11. Exemplarily, the liquid inlet pipe 12 and the inlet 112 of the heat-conducting container 11 are sealed together, and the sealing method can be welding or a sealing ring assembly connection.

[0056] Considering the composition of the airflow channels in the heat-conducting container 11, at least one side wall of the heat-conducting container 11 has multiple air outlets 113. Each air outlet 113 is a hole directly formed on the corresponding side wall surface. Thus, each air outlet 113 communicates with the cavity 111, forming multiple airflow channels inside the heat-conducting container 11. These airflow channels are not constrained channels in a fixed area, allowing them to adapt to the random flow characteristics of the airflow. Gas molecules, due to their random activity, have relatively random flow speeds and directions. Therefore, this arrangement of air outlets 113 facilitates the separation of different active gas molecules without affecting the flow speed of each gas molecule. This disclosure does not limit the shape, size, or location of the air outlets 113, as long as it ensures that the oxygen released inside the heat-conducting container 11 can flow out to the external environment through the air outlet 113, and that the replenishing water inside the heat-conducting container 11 does not flow out to the external environment through the air outlet 113. This ensures that the replenishing water will not block the location of the air outlet 113, thereby not affecting the oxygen discharge. For example, the air outlet 113 can be any regular shape among square, circle, trapezoid or polygon, or the air outlet 113 can also be an irregular shape, depending on the actual application scenario.

[0057] Further considering the method where the makeup water in the heat-conducting container 11, whether deoxygenated once or not, flows out through the liquid flow channel to the bottom of the heat-conducting container 11, the liquid in the cavity 111 can be made to flow out to the external environment through the liquid flow channel by pressure difference, or the makeup water can flow out to the external environment by its own weight. This disclosure uses the scheme of makeup water flowing out to the external environment by its own weight as an example for illustration.

[0058] Considering that after the replenishing water flows out to the external environment, it needs to undergo secondary deoxygenation, the replenishing water is set to drip downward through the liquid flow channel under its own weight. During the dripping process, under the action of the upward flowing high-temperature airflow, it undergoes thermal deoxygenation below the heat-conducting container 11, and oxygen is released.

[0059] Specifically, as shown in Figure 3, the bottom wall of the heat-conducting container 11 has multiple liquid distribution holes 114. These holes 114 can be understood as multiple small orifices or fine pores formed on the bottom wall of the heat-conducting container 11. Each small orifice or fine pore has the same diameter, enabling the same liquid dripping speed and single drip volume under the same pressure and temperature conditions. Alternatively, liquid distribution hole 114 structures with different radial dimensions can be used to adapt to the needs of different scenarios.

[0060] For example, each liquid distribution hole 114 is connected to the cavity 111, forming multiple liquid flow channels. The liquid distribution holes 114 can be holes directly formed on the bottom wall, and multiple rows and columns of liquid distribution holes 114 are arranged. In this way, each liquid distribution hole 114 is connected to the cavity 111, which can form multiple liquid flow channels between the inside of the heat-conducting container 11 and the external environment. These liquid flow channels are not constrained channels of fixed areas, and can adapt to the random flow characteristics of liquid flow. Liquid molecules have random flow speed and direction due to the randomness of their own activity. Therefore, the arrangement of this liquid distribution hole 114 can facilitate the diversion of liquid molecules with different activity, but does not affect the flow speed of each liquid molecule. This disclosure does not limit the shape, size and setting position of the liquid distribution hole 114, as long as it can ensure that the replenishment water stored in the heat-conducting container 11 can flow out to the external environment through the liquid distribution hole 114, and that the oxygen that is initially released in the heat-conducting container 11 will not flow out to the external environment through the liquid distribution hole 114. For example, the liquid distribution hole 114 can be any regular shape among square, circle, trapezoid or polygon, or the liquid distribution hole 114 can also be an irregular shape, depending on the actual application scenario.

[0061] Considering that the equalizing hole 114 enables the makeup water to drip, the diameter of the equalizing hole 114 can be constrained within different ranges depending on the application scenario of the deaerator assembly 1. For example, taking the deaerator assembly 1 as an example applied to different steam generators (including evaporative condensers), the diameter range of the equalizing hole 114 is related to the makeup water volume of the steam generator. For example, in this disclosure, the diameter range of the equalizing hole 114 can be between 2mm and 10mm, with the endpoint values ​​included within the range of this solution. Thus, in functional equipment such as steam generators (evaporative condensers), the equalizing hole 114 of the heat-conducting container 11 can achieve the effect of makeup water dripping downwards.

[0062] Based on the above functional implementation, all of which are realized according to the structure of the heat-conducting container 11, the specific structural composition of the deoxygenation component 1 of this disclosure will be further defined below with reference to specific examples.

[0063] In this embodiment, the heat-conducting container 11 of this disclosure is constructed as a box-shaped structure. Each wall surface of the box-shaped structure is made of a heat-conducting plate, which is a plate-shaped structure made of a heat-conducting material. Alternatively, the heat-conducting plate can also be a sheet-shaped structure made of a heat-conducting material. The box-shaped structure is used to provide a cavity 111 with defined spatial dimensions. For example, the heat-conducting material may include any one of the following: metallic materials, carbon materials, and ceramic materials. These three materials have high thermal conductivity, which can better achieve the heat conduction performance of the heat-conducting container 11 in this solution. Accordingly, the liquid inlet 112 and the air outlet 113 are provided on the heat-conducting plate on the corresponding side, and the liquid equalization hole 114 is provided on the heat-conducting plate located at the bottom.

[0064] Furthermore, the heat-conducting container 11 is positioned upstream of the high-temperature airflow. The upstream region refers to the area where the high-temperature airflow flows upwards. This region is maintained within a preset distance from the starting point of the high-temperature airflow. This embodiment does not limit this preset distance, as long as it ensures that the temperature of the heat-conducting container 11 is sufficient to saturate the replenishing water. This preset distance depends on the heat dissipation conditions of the actual application scenario.

[0065] The heat-conducting container 11 of this embodiment can be a detachable structure or an integrally formed structure.

[0066] As shown in Figure 1, if the heat-conducting container 11 adopts a detachable structure, the heat-conducting container 11 includes a cover plate 115 at the top and a box body 116 at the bottom. The cover plate 115 can be detachably closed onto the opening of the box body 116, thus facilitating cleaning of the box body 116 by opening the cover plate 115. Furthermore, an air outlet 113 can be directly formed on the upper part of the side wall of the cover plate 115 and the box body 116, a liquid inlet 112 can be formed on at least one side wall of the box body 116, and a liquid distribution hole 114 can be directly formed on the bottom wall of the box body 116.

[0067] Alternatively, the heat-conducting container 11 includes a box body 116 at the top and a bottom plate at the bottom, with the bottom plate detachably covering the opening of the box body 116. In this way, during the manufacturing process, an air outlet 113 and a liquid inlet 112 can be directly formed on the side wall and / or top wall of the box body 116, while a liquid equalization hole 114 can be directly formed on the bottom plate.

[0068] In this embodiment, at least one liquid inlet 112 is included. The number of liquid inlets 112 is related to the diameter of the liquid inlets 112 and the actual liquid inlet volume, and this solution does not limit this. The liquid inlet 112 can be disposed on the cover plate 115 or formed on the side wall of the box body 116. Multiple air outlets 113 can be included, and multiple air outlets 113 are respectively formed on at least one side wall of the box body 116 and / or the cover plate 115, and are limited to the upper area of ​​each side wall, so as to prevent the replenishing water from flowing out from the air outlet 113. For example, the air outlet 113 can be disposed on one side wall, two side walls, three side walls or all side walls. Multiple liquid equalization holes 114 can be included, and multiple liquid equalization holes 114 are disposed on the bottom wall or bottom plate of the box body 116. This solution does not limit the shape, size and specific location of the liquid inlet 112, air outlet 113 and liquid equalization hole 114, but depends on the needs of the actual application scenario.

[0069] When the heat-conducting container 11 adopts an integrally molded box-shaped structure, each wall surface of the box-shaped structure is the aforementioned heat-conducting plate. During the molding process of the box-shaped structure, the aforementioned liquid inlet 112, air outlet 113 and liquid equalization hole 114 can be molded in one step, which can save process costs.

[0070] For example, the heat-conducting plate constituting the heat-conducting container 11 can be made of sheet metal, and this sheet metal structure can be connected in a detachable manner. Either side of the sheet metal structure constituting the heat-conducting container 11 can be configured with a detachable connection. The detachable connection can be any of the following: threaded assembly, snap-fit, tenon and mortise assembly, plug-in limiting, or lap joint. This facilitates the manufacturing process of the heat-conducting container 11 while also ensuring that the sheet metal material itself possesses thermal conductivity.

[0071] Using the deoxygenation component 1 disclosed herein, a heat-conducting container 11 with inherent thermal conductivity is applied. In a high-temperature environment, heat is conducted through the heat-conducting container 11, raising its own structural temperature. During application, the deoxygenated liquid flows into the cavity 111 through the inlet 112 on one side of the heat-conducting container 11. The liquid undergoes initial heating inside the heat-conducting container 11, achieving the first deoxygenation. Oxygen is released inside the heat-conducting container 11, and this oxygen flows to the external environment through the airflow channel. At this point, the deoxygenated liquid stored in the cavity 111 is the liquid after the first deoxygenation. This deoxygenated liquid then flows out through the liquid flow channel to the bottom of the heat-conducting container 11. Subsequently, the deoxygenated liquid undergoes a second deoxygenation under the action of a high-temperature airflow, and residual oxygen continues to be released below the heat-conducting container 11. The deoxygenation component 1 disclosed herein has a compact overall structure, occupies little space, is easy to assemble, can perform two deoxygenation processes on the liquid to be deoxygenated, and is easy to install in various equipment containers, especially suitable for deoxygenation operations on makeup water.

[0072] Considering the application of the deoxygenation component 1 in the evaporative condenser 2, this disclosure also provides a scheme for the evaporative condenser 2. Referring to Figures 1-6, the specific structure of the evaporative condenser 2 with the deoxygenation component 1 installed is described.

[0073] The scenario for the horizontal shell structure used in this disclosure is that it adopts a shell-and-tube heat exchanger, in which high-temperature refrigerant vapor inside the heat exchange tube bundle 22 is condensed to heat the demineralized water on the outer side of the heat exchange tube bundle 22, and the demineralized water absorbs heat and its temperature rises to obtain high-temperature water vapor.

[0074] For example, a horizontal shell-and-tube heat exchanger is used as a steam generator (i.e., a condenser or condensing device), which includes a shell 21, tube sheets at both ends of the shell 21, water chambers (tube boxes) at both ends, heat exchange tube bundles 22 inside the shell 21, various inlet and outlet pipes, gas-liquid filter screens 23, etc.

[0075] Specifically, the evaporative condensing device 2 provided in this disclosure includes a shell 21 and the aforementioned deoxygenation component 1. Exemplarily, the shell 21 adopts a shell-and-tube structure. Specifically, a heat exchange tube bundle 22 is disposed in the lower region of the shell 21, and the lower region of the shell 21 stores the aforementioned deoxygenated liquid (i.e., makeup water). The heat exchange tube bundle 22 is immersed in the deoxygenated liquid. The deoxygenated liquid vaporizes at a high temperature to form an upward high-temperature gas flow. A transverse space is provided in the upper region of the shell 21 for the flow of the high-temperature gas flow, and the deoxygenation component 1 is installed in the transverse space. Exemplarily, the evaporative condensing device 2 provided in this disclosure adopts a horizontal shell-and-tube structure.

[0076] In this embodiment, the deoxygenation component 1 is installed above the heat exchange tube bundle 22 immersed in the deoxygenated liquid. Based on the characteristic of the refrigerant liquefying and releasing heat in the heat exchange tube bundle 22, the tube wall temperature of the heat exchange tube bundle 22 is relatively high. Thus, heat conduction occurs between the heat exchange tube bundle 22 and the deoxygenated liquid, thereby raising the temperature of the deoxygenated liquid until it vaporizes and forms an upward-flowing high-temperature airflow, i.e., high-temperature water vapor, in the upper region of the shell 21 (i.e., the upper shell side region). The high-temperature water vapor flows upward and conducts heat conduction with the heat-conducting container 11, thereby ensuring that the deoxygenated liquid undergoes the first deoxygenation inside the cavity 111 of the heat-conducting container 11. In addition, the upward flow of high-temperature water vapor can perform a second deoxygenation on the deoxygenated liquid dripping downward through the liquid equalization hole 114.

[0077] Meanwhile, the area above the heat exchange tube bundle 22 inside the evaporative condenser 2 disclosed herein is already in an empty state. In this way, the deoxygenation component 1 can be installed in the space inside the shell 21, that is, the deoxygenation component 1 is installed in the upper part of the shell side. It can also utilize the high-temperature airflow energy of the high-temperature water vapor produced by the evaporative condenser 2 itself to further reduce the oxygen content of the makeup water to be deoxygenated under the original evaporative heat transfer function. This can prevent oxidation corrosion from occurring in the assembly or welding gaps between the heat exchange tube bundle 22 and the corresponding metal structure inside the shell 21.

[0078] It should be noted that in the entire steam generator system, this condenser is also used to produce high-temperature steam for demineralized water, so it can also be called a steam generator (i.e., evaporative condensing device 2). In conventional air conditioning units, condensers and evaporators are distinguished based on the phase change state of the refrigerant. For example, if the refrigerant condenses in the heat exchanger, this component is a condenser; if the refrigerant evaporates in the heat exchanger, this component is an evaporator. Corresponding to the evaporative condensing device 2 of this disclosure, the heat energy source is the heat release from the liquefaction of the condenser in the heat exchange tube bundle 22, and the water vapor discharged from the shell 21 is used. Therefore, the evaporative condensing device 2 protected by this disclosure can be called a condenser or an evaporator.

[0079] Considering the outflow of oxygen released from the deoxygenation assembly 1 in the upper shell region, to prevent it from being re-immersed in the deoxygenating liquid and oxidizing and corroding the gaps of various assemblies and welds, the evaporative condenser 2 of this disclosure also includes an outlet pipe 25 and a gas-liquid filter screen 23. The outlet pipe 25 facilitates the outflow of oxygen, while the gas-liquid filter screen 23 prevents the outflow of water vapor and oxygen mixed with liquid, ensuring the dryness of the water vapor discharged from the outlet.

[0080] Specifically, an outlet pipe 25 is connected to the top of the shell 21. Along the height direction of the shell 21, the vertical projection of the deoxygenation component 1 relative to the bottom surface of the shell 21 is the first vertical projection area, and the vertical projection of the outlet pipe 25 relative to the bottom surface of the shell 21 is the second vertical projection area. The distance between the first and second vertical projection areas is the farthest line segment inside the shell 21. The shell 21 is a cylindrical structure extending in the horizontal plane. Along the length direction of the shell 21, the outlet pipe 25 and the deoxygenation component 1 are located at opposite ends inside the shell 21. This ensures that the deoxygenated water flowing out of the device has a sufficiently long path and time to enter the bottom full liquid area (heat exchange tube area) to reduce the suction and liquid carryover phenomenon caused by the airflow generated by water evaporation hitting the liquid deoxygenated water, and further ensures the dryness of the water vapor discharged from the outlet pipe 25.

[0081] It should be noted that the farthest line segment between the first and second vertical projection areas can be drawn by connecting the center points of each projection area. Alternatively, depending on the shape of each projection area, the endpoints or side lines in the same direction can also be selected for connection.

[0082] Specifically, a gas-liquid filter screen 23 is installed inside the housing 21. The gas-liquid filter screen 23 is laid horizontally above the deoxygenation component 1 and located below the gas outlet pipe 25. This disclosure does not limit the pore size and dimensions of the filter screen 23, or the number of filter layers, as long as it can prevent the discharge of liquid water along with water vapor and oxygen.

[0083] For example, the liquid inlet pipe 12 of the deoxygenation component 1 and the liquid replenishment port on the housing 21 can be connected by a flexible hose or a seamless steel pipe, which makes it easy to add liquid water to the heat-conducting container 11 of the deoxygenation component 1.

[0084] For example, one end of the liquid inlet pipe 12 of the deoxygenation assembly 1 is assembled and connected to the liquid replenishment port of the shell 21. In this way, when performing the liquid replenishment process of the evaporative condenser 2, the replenishing water can directly enter the inner cavity 111 of the heat-conducting container 11 of the deoxygenation assembly 1. This further ensures that all the replenishing water added through the liquid replenishment port can be immersed in the heat exchange area of ​​the shell side after deoxygenation. In this way, the oxygen content of the liquid in the heat exchange area is greatly reduced, which can further alleviate the problem of oxidation corrosion at various metal connection points or metal surfaces inside the shell 21.

[0085] Furthermore, considering the assembly method of the deaerator assembly 1 within the housing 21, the housing 21 has a support plate 24 for supporting the heat exchange tube bundle 22 within the housing 21. Multiple support plates 24 are provided, and the deaerator assembly 1 is mounted on the support plate 24 located on the side of the housing 21 away from the outlet pipe 25. For example, the support plate 24 is vertically arranged within the housing 21, and multiple mounting holes are provided through the support plate 24. Each heat exchange tube bundle 22 passes through a corresponding mounting hole. Thus, the multiple support plates 24 are spaced apart, enabling them to simultaneously support the weight of different positions of the heat exchange tube bundle 22.

[0086] Considering further assembly between the deoxygenation assembly 1 and the support plate 24, the bottom surface of the heat-conducting container 11 can be directly connected to the top surface of the support plate 24. This connection includes any one of welding, threaded assembly, snap-fit ​​connection or plug-in connection.

[0087] Considering further assembly between the deaerator assembly 1 and the support plate 24, as shown in Figure 1, the deaerator assembly further includes a connector 3. At least a portion of the connector 3 is connected to the bottom surface of the heat-conducting container 11, or at least a portion of the connector 3 is connected to the top or side surface of the support plate 24. This connection includes any one of welding, threaded assembly, snap-fit ​​connection, or plug-in connection. Exemplarily, the connector 3 uses the same heat-conducting material as the heat-conducting container 11. Exemplarily, both the connector 3 and the heat-conducting container 11 are sheet metal parts. Sheet metal parts are parts made from metal sheets through stamping, bending, shearing, welding, and other processing processes. Steel is commonly used in shells and tubes, such as carbon steel, stainless steel, galvanized steel sheets, etc., which have good processing performance and are inexpensive. Copper can be used if a material with higher thermal conductivity is required, but the cost is higher.

[0088] For example, the connector 3 is constructed as a plate structure, such as a flat plate structure, which facilitates welding or assembly connection with the bottom surface of the heat-conducting container 11.

[0089] For example, the connector 3 is constructed as a bent structure, one side of which is convenient for welding or assembly connection with the bottom surface of the heat-conducting container 11, and the other side of which is convenient for welding or assembly connection with the support plate 24.

[0090] For example, the connector 3 can be integrally formed with the heat-conducting container 11. This facilitates the assembly of the heat-conducting container 11 relative to the support plate 24.

[0091] For example, the connection between the connector 3 and the support plate 24 is a detachable connection. This detachable connection includes any one of threaded assembly, snap-fit ​​connection, or plug-in connection.

[0092] The deoxygenation component 1 and evaporative condenser 2 of this disclosure are applied, especially the addition of the deoxygenation component 1 in the upper shell-side region of the condenser. For example, the heat-conducting container 11 of the deoxygenation component 1 is a square box-shaped structure. Further, this square box-shaped structure is formed by bending and welding a square sheet metal part around its perimeter. The upper region of the four walls of the square box-shaped structure is designed with intermittently distributed square air outlets 113, and the bottom of the square box-shaped structure is designed with evenly distributed circular liquid equalization holes 114. In addition, the deoxygenation component 1 is welded and fixed to the support plate 24 via a connector 3. The connector 3 can be a bracket, and the bracket adopts an L-shaped bracket. Demineralized water (i.e., makeup water, deoxygenated liquid) enters the deoxygenation component 1 from the liquid inlet pipe 12 on the side of the shell 21. By adding the deoxygenation component 1 in the region above the heat exchange tube bundle 22 of the steam generator, oxidation and corrosion of the shell 21, shell tubes, and the connection points with the shell tubes can be avoided, reducing system costs and equipment installation space.

[0093] In practical applications, demineralized water (i.e., replenishing water, water to be deoxygenated) enters the internal space of the thermal deoxygenation assembly 1, i.e., the cavity 111 of the heat-conducting container 11, through the liquid inlet pipe 12 on the side of the shell 21. The demineralized water achieves a uniform downward dripping effect through the equalization hole 114. The steam generated by the full liquid evaporation of the heat exchange tube bundle 22 below first heats the downward dripping demineralized water (i.e., heat conduction), causing some oxygen in the water to escape. Secondly, the steam generated by the evaporation of the heat exchange tube bundle 22 below will contact the equalization plate and the cover plate 115 (i.e., the various surfaces of the heat-conducting container 11), and transfer heat to the demineralized water stored inside the box-shaped structure, further heating the demineralized water (equivalent to secondary heating). The oxygen that escapes from the demineralized water inside the box-shaped structure gathers above the internal space of the heat-conducting container 11 and flows out through the vent pipe 25.

[0094] In this way, the deoxygenated water, after undergoing two thermal deoxygenation processes, drips into the heat exchange area of ​​the heat exchange tube bundle 22, where it exchanges heat with the high-temperature medium inside the tubes to produce steam. Oxygen, carried by the produced steam, passes through the gas-liquid filter screen 23 and reaches the outlet pipe 25 on the shell side. An oxygen removal assembly 1 is added above the heat exchange tube bundle 22 to prevent oxygen from contacting easily oxidizing and corroding areas in the steam generator, such as the connection between the heat exchange tube bundle 22 and the support plate 24 or tube sheet, where the metal wall temperature is high, water flow turbulence is intense, and there are many assembly or welding gaps. Furthermore, the overall structure of the oxygen removal assembly 1 is positioned as far away as possible from the outlet pipe 25 of the steam generator (evaporative condenser 2). This ensures that the deoxygenated water flowing from the oxygen removal assembly 1 has sufficient time to enter the bottom full liquid area (heat exchange tube area) to reduce the suction and liquid carryover phenomenon caused by the airflow generated by water evaporation impacting the liquid deoxygenated water, further ensuring the dryness of the water vapor discharged from the outlet pipe 25.

[0095] It should be noted that the demineralized water drips downwards from the square box-shaped structure (i.e., the bottom surface of the heat-conducting container 11), while water vapor flows upwards from the heat exchange tube bundle 22 area. When the water droplets are heated, oxygen escapes. Since oxygen is less dense than water, it flows upwards with the water vapor and does not flow downwards to contact the support plate 24 and the tube bundle. Simultaneously, the heat exchange tube bundle 22 area is immersed in the demineralized water, with the liquid level slightly higher than the tube bundle 22. The water temperature near the liquid surface is higher, making it difficult for oxygen to dissolve and enter the high-temperature water. Thus, the areas in the steam generator (i.e., the evaporative condenser 2) prone to oxidation and corrosion are the connections between the heat exchange tube bundle 22 and the support plate 24 and tube sheet. These areas have high metal wall temperatures, intense water flow disturbances, and numerous assembly or welding gaps. The structure disclosed in this invention ensures that oxygen can only exist above the liquid surface, preventing these easily oxidized and corroded areas inside the shell 21 from contacting oxygen.

[0096] Specifically, the evaporative condenser 2 disclosed herein further includes a high-temperature steam inlet 26 and a high-temperature steam outlet 27, both of which are connected to the shell side of the casing 21. With these two inlets and outlets, the liquid level in the flooded region containing the heat exchange tube bundle 22 within the casing 21 is slightly higher than the top surface of the heat exchange tube bundle 22. This prevents the metal structure area connected to the heat exchange tube bundle 22 from contacting oxygen on the liquid surface and thus avoiding corrosion.

[0097] Furthermore, the evaporative condenser 2 disclosed herein also includes tube boxes on both sides of the housing 21, which are connected to the aforementioned high-temperature steam inlet 26 and high-temperature steam outlet 27.

[0098] In summary, the deoxygenation component 1 and the evaporative condenser 2 equipped with the deoxygenation component 1 provided in this disclosure can simultaneously deoxygenate the replenishment water during the replenishment process of the full liquid in its shell side. At the same time, it can also utilize the high-temperature steam produced by the evaporative condenser 2 itself, eliminating the need to install a large deoxygenation device outside the evaporative condenser 2, thus saving system costs.
