Description

Technical Field

[0001] The present application relates to the field of steam generators with thermal deoxidation function, and in particular to a deoxidation component and an evaporative condensing device. Background Art

[0002] As a traditional large-capacity evaporator, the horizontal tube full liquid evaporator is widely used in air conditioning refrigeration, heat pump heating, chemical industry and other fields due to its low cost and strong stability. When the evaporator is in operation, the liquid to be evaporated fills the shell side space outside the heat exchange tube (the liquid level is usually slightly higher than the highest point of the heat exchange tube row), and the heat released by the fluid in the tube is transferred to the liquid outside the tube through the tube wall and the fins, causing the liquid to change phase, and the gas generated by boiling heat exchange is discharged from the top of the heat exchanger.

[0003] If the horizontal tube full liquid evaporator is used as a steam generating device, the shell side space outside the heat exchange tube is boiling water, and other hot working fluids are inside the tube. The water is heated by the heat exchange tube to become high-temperature steam. In the high-temperature steam heat pump unit, the steam generator is a device that directly generates steam, and its durability is closely related to the water quality in the shell. If the dissolved oxygen content in the feed water is too much, it will cause serious oxidation corrosion to the shell and tube materials, and even cause serious accidents. The parts of the steam generating device that are prone to oxidation corrosion are the connection between the heat exchange tube bundle and the support plate and tube sheet, where the metal wall temperature is high, the water flow disturbance is severe, and there are many assembly or welding gaps. In the boiler system, there are many ways to remove dissolved oxygen in the feed water, such as thermal deoxidation, vacuum deoxidation, chemical deoxidation, rust deoxidation, etc. Among them, the principle of thermal deoxidation is based on the Henry-Dalton theorem, using part of the output steam to heat the feed water to a saturated state. At this time, the solubility of oxygen in the water is zero, and oxygen is precipitated and discharged from the water. The deoxygenated water is supplied to the boiler to generate steam.

[0004] As a steam generating device, the horizontal tube full liquid evaporator can use part of the produced steam to heat the feed water. If a separate thermal deaerator is installed, the system cost and equipment installation space will increase. Summary of the invention

If a separate thermal deaerator is set, the system cost and equipment installation space will increase.

[0006] The deoxygenation component provided by the present invention comprises: a heat-conducting container having a cavity inside; a liquid inlet on one side of the heat-conducting container, and a liquid flow channel and an air flow channel between the cavity and the external environment; the liquid to be deoxygenated flows to the cavity through the liquid inlet; at least part of the liquid to be deoxygenated releases oxygen in the heat-conducting container and flows to the external environment through the air flow channel; and / or at least part of the liquid to be deoxygenated flows to the bottom of the heat-conducting container through the liquid flow channel, and undergoes a second deoxygenation under the action of the high-temperature airflow.

[0007] Wherein, the external environment is maintained in the upstream area of ​​the high-temperature airflow.

[0008] Exemplarily, at least a portion of the liquid to be deoxygenated is thermally deoxygenated when in contact with the inner wall of the heat-conducting container or in the cavity of the heat-conducting container, and oxygen is released in the cavity of the heat-conducting container.

[0009] Wherein, at least one side wall of the heat-conducting container has a plurality of air outlets, and each of the air outlets is respectively connected to the cavity to form a plurality of the air flow channels.

[0010] Wherein, at least a portion of the liquid to be deoxygenated drips downward through the liquid flow channel under the action of its own weight, and releases oxygen below the heat-conducting container under the action of the upward high-temperature airflow.

[0011] Wherein, the bottom wall of the heat-conducting container has a plurality of liquid distribution holes, and each of the liquid distribution holes is connected to the cavity respectively to form a plurality of the liquid flow channels.

[0012] Wherein, the diameter of the liquid equalizing hole ranges from 2mm to 10mm.

[0013] The heat-conducting container is constructed as a box-shaped structure, each side of the box-shaped structure adopts a heat-conducting plate, and the heat-conducting container is located in the upstream area of ​​the high-temperature airflow.

[0014] Wherein, the heat-conducting container comprises a cover plate and a box body, and the cover plate is detachably covered on the opening of the box body.

[0015] Wherein, the heat-conducting container is constructed as an integrally formed structure.

[0016] Wherein, the heat-conducting container is constructed as a detachable sheet metal structure.

[0017] The evaporative condensing device provided by the present invention comprises a shell and the aforementioned deoxygenation component, wherein a heat exchange tube bundle is arranged in the lower area of ​​the shell and the liquid to be deoxygenated is stored, and the heat exchange tube bundle is immersed in the liquid to be deoxygenated; the liquid to be deoxygenated is vaporized in a high temperature state to form the upward high-temperature airflow, and a lateral space for the high-temperature airflow to flow is reserved in the upper area of ​​the shell, and the deoxygenation component is installed in the lateral space.

[0018] Among them, the top of the shell is connected to an outlet pipe, and along the height direction of the shell, the vertical projection of the deoxygenation component relative to the bottom surface of the shell is a first vertical projection area, the vertical projection of the air outlet relative to the bottom surface of the shell is a second vertical projection area, and the distance between the first vertical projection area and the second vertical projection area is the farthest line segment in the shell.

[0019] Wherein, a gas-liquid filter is arranged in the shell, and the gas-liquid filter is laid horizontally above the deoxidation component and is located below the air outlet pipe.

[0020] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0021] The deoxygenation assembly and evaporative condensing device provided in the embodiments of the present application use a heat-conducting container that has heat-conducting properties, conduct heat to the heat-conducting container in a high-heat environment, and increase the temperature of the heat-conducting container's own structure.

[0022] At this time, the liquid to be deoxygenated stored in the cavity is the liquid to be deoxygenated after the first deoxygenation, and then the liquid to be deoxygenated flows out to the bottom of the heat-conducting container through the liquid flow channel. After that, the liquid to be deoxygenated is deoxygenated for the second time under the action of the high-temperature airflow, and the residual oxygen continues to precipitate under the heat-conducting container.

The evaporative condensing device equipped with the deoxygenation component can use its own high-temperature water vapor as a high-temperature airflow to provide a secondary heating environment for the thermal container, and perform a second deoxygenation on the liquid to be deoxygenated flowing out of the thermal container. Exemplarily, the liquid to be deoxygenated is replenishment water. Furthermore, installing the deoxygenation component inside the equipment structure of the existing horizontal tube full liquid evaporator can reduce system costs and external equipment installation space, and at the same time, it can also prevent oxidative corrosion of the internal structure by dissolved oxygen in the replenishment water.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0040] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a change in posture or a change in motion state, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may 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 herein have been interpreted accordingly.

[0041] The deoxygenation component provided by the present invention, based on its overall structural device, occupies a small space area, and is convenient for thermal deoxygenation of liquid containing dissolved oxygen inside large equipment. It can be applied to any application scenario requiring thermal deoxygenation. The following takes the application of the deoxygenation component to a condenser as an example to explain the specific structure of the present invention in detail.

[0042] The condensers currently in use are generally divided into air-cooled condensers and water-cooled condensers. The working principle of the air-cooled condenser is as follows: the refrigerant releases heat in the heat exchange tube bundle and condenses into liquid. When the wind flows through the outside of the heat exchange tube bundle, it absorbs heat and the temperature rises. The water-cooled condenser uses the liquid outside the heat exchange tube bundle to absorb heat and increase the temperature to vaporize into steam. For the water-cooled condenser, it uses the liquid immersed outside the heat exchange tube bundle to absorb the heat released by the condensation of the refrigerant. The deoxygenated liquid absorbs heat and the temperature rises. When the temperature is higher than the saturation temperature under the current pressure, it will evaporate into a gaseous state and obtain high-temperature water vapor. In this way, the amount of liquid stored in the water-cooled condenser will gradually decrease. Therefore, the water-cooled condenser needs to be replenished to ensure that the shell-side liquid in the water-cooled condenser can always absorb the heat of the heat exchange tube bundle, thereby ensuring the basic function of the condenser.

[0043] In the case where the condenser needs to be replenished, the replenishment is generally a liquid containing dissolved oxygen. If the dissolved oxygen content in the replenishment is too high, it will cause serious oxidation corrosion to the shell and tube materials of the condenser, and even cause serious accidents. The parts of the steam generating device that are prone to oxidation corrosion are the joints between the heat exchange tube bundle and the support plate and the tube sheet, where the metal wall temperature is high, the water flow disturbance is severe, and there are many assembly or welding gaps. In the boiler system, there are many ways to remove dissolved oxygen in the feed water, such as thermal deoxygenation, vacuum deoxygenation, chemical deoxygenation, rust deoxygenation, etc. The principle of thermal deoxygenation is based on the Henry-Dalton theorem, which uses part of the produced steam to heat the feed water to a saturated state. At this time, the solubility of oxygen in the water is zero, and oxygen is precipitated and discharged from the water. The water after thermal deoxygenation can be supplied to the boiler to generate steam.

[0044] The existing deaerator components are large in overall size and occupy a lot of space. They can only be installed separately outside the condenser. If a separate thermal deaerator is installed, the system cost and equipment installation space will increase.

[0045] In order to alleviate the above problems, the present invention provides a deoxidation assembly, which has a small structure size and is easy to install, and can be installed in existing large, medium or small liquid storage equipment. Taking a steam generator as an example, a steam generator device is used to produce high-temperature water vapor.

[0046] For example, steam generators can be used in food processing, textile printing and dyeing, pharmaceutical industry, chemical industry, papermaking industry, heating system, power generation, cleaning and disinfection, agricultural humidification and car beauty industries. For example, in the food processing industry, steam generators can be used for heating, sterilization, cooking and other processes to ensure food safety and quality. In the textile industry, steam is used to pre-treat, dye, and shape fabrics to improve the quality and feel of fabrics. In the pharmaceutical process, steam is used for sterilization, drying, extraction and other links to ensure the sterile environment and product quality of drug production. In the chemical industry, steam is used as a heat source or reaction medium to participate in chemical reactions and promote the mixing and conversion of materials. In the papermaking industry, steam is used for steps such as cooking, bleaching, and drying of raw materials to improve the physical properties of paper. In the heating system, especially in the winter heating system, steam is transported to each room through pipes to provide warmth for the building. In power generation: thermal power plants use high-temperature and high-pressure steam generated by coal combustion to drive steam turbines to generate electricity. In cleaning and disinfection, medical equipment, dining utensils, etc. need to be regularly sterilized with steam at high temperatures to kill bacteria and viruses. In agricultural humidification, steam is used in greenhouses to increase air humidity and improve the growth environment of plants. In car beauty, steam is used to clean the surface of the vehicle to remove stains without damaging the paint.

[0047] Furthermore, the specific structural composition of the steam generator heat pump unit is the same as that of a conventional air-conditioning unit, which consists of four major parts: a compressor, an evaporator, a throttling device and a condenser. Among them, the high-temperature steam generated by the compressor enters the tube side of the condenser (such as high-temperature refrigerant steam). The high-temperature refrigerant steam in the tube side of the evaporator heats the desalted water in the shell side to produce high-temperature water vapor. The throttling device throttles and reduces the pressure of the liquid refrigerant condensed from the tube side of the condenser. Afterwards, the throttled and reduced-pressure refrigerant absorbs heat in the evaporator and evaporates into a low-temperature and low-pressure gas, and enters the compressor intake port. Other supporting equipment includes water pumps, electrical systems, filters, and so on.

[0048] For example, there are many types of steam generators, such as producing steam by electrically heating water and producing steam by burning gas or oil.

[0049] Exemplarily, taking the scenario where the deoxygenation component is applied to an evaporative condenser as an example, the structure of the deoxygenation component of the present invention is specifically described.

[0050] The liquid to be deoxygenated of the present invention can be deionized water or a mixed chemical liquid. Exemplarily, deionized water is also called deionized water or pure water, which refers to water from which most or all ions (such as sodium, calcium, magnesium, chlorine, etc.) in water are removed by physical or chemical methods. Deionized water is used to produce water vapor in the equipment. Exemplarily, the mixture of mixed chemical liquids has different boiling points. The medium is heated to obtain medium vapor with a low boiling point, and the physical properties can be separated. The present invention does not limit the components of the liquid to be deoxygenated, and the specific application scenario shall prevail.

[0051] like Figure 1-Figure 6 As shown, the deoxygenation component 1 provided by the present invention and the evaporative condensation device 2 equipped with the deoxygenation component 1 are provided, wherein the deoxygenation component 1 includes: a heat-conducting container 11 having a cavity 111 inside; illustratively, the heat-conducting container 11 can be understood as a container made of a heat-conducting material. Based on this performance, 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 environment or the low-temperature environment, so that the heat-conducting container 11 is kept in balance with the ambient temperature. The heat-conducting container 11 of the present invention has a liquid inlet 112 on one side of the container, and the liquid inlet 112 is connected to the cavity 111 of the heat-conducting container 11, and the replenishing water (that is, the deoxygenated liquid) flows into the cavity 111 through the liquid inlet 112. The present invention does not limit the shape, size and setting position of the liquid inlet 112, as long as it can ensure that the replenishing water flows from the liquid inlet 112 into the cavity 111, and the replenishing water in the cavity 111 will not flow out to the external environment through the liquid inlet 112. Exemplarily, the liquid inlet 112 may be any regular shape such as square, circle, trapezoid or polygon, or the liquid inlet 112 may be an irregular shape, depending on the actual application scenario.

[0052] The deoxygenation assembly 1 of the present invention also includes a liquid flow channel and an air flow channel, and the liquid flow channel and the air flow channel are both formed between the cavity 111 and the external environment. Exemplarily, the liquid flow channel and the air flow channel can be understood as physical structure channels, such as: channels connected with physical pipelines, and can also be understood as functional channels, such as: replenishing water flows through the liquid flow channel, and flows out of the cavity 111 of the heat-conducting container 11 to the external environment, without the need to use a physical structure to standardize a fixed channel area.

[0053] With the above structure, the rehydration water of the present invention, that is, the liquid to be deoxygenated, flows to the cavity 111 through the liquid inlet 112. Based on the fact that the heat-conducting container 11 is placed in a high-heat environment, the temperature in the cavity 111 is relatively high through heat conduction. It can be understood that the liquid to be deoxygenated is heated in the heat-conducting container 11 for a second time. The relatively high temperature can heat the rehydration water in the cavity 111 to a saturated state. In this saturated state, the solubility of oxygen in the rehydration water is zero, and oxygen is precipitated from the water, thereby forming at least part of the liquid to be deoxygenated to precipitate oxygen in the cavity 111 of the heat-conducting container 11. Since the gas is continuously flowing, the oxygen analyzed in this part flows to the external environment through the air flow channel, thereby achieving the effect of the first deoxygenation.

[0054] Furthermore, after the first deoxygenation, the replenishing water in the cavity 111 of the heat-conducting container 11 flows out through the liquid flow channel to the bottom of the heat-conducting container 11, and the second deoxygenation is carried out under the action of the high-temperature airflow. It should be pointed out that the conditions set by the external environment of this scheme are: to maintain in the upstream area of ​​the high-temperature airflow, which can be understood as the external environment is the area where the high-temperature airflow flows upward, so that there will be a continuous high-temperature airflow acting on the heat-conducting container 11, which can ensure that the heat-conducting container 11 will always exchange heat with the heat source (that is, the high-temperature airflow), and further ensure the necessary conditions for the first deoxygenation, that is, the thermal conductivity characteristics 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, and 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, and then reach a saturated state. In this saturated state, the solubility of oxygen in the replenishing water is zero, and the residual oxygen is precipitated again, thereby achieving the effect of the second deoxygenation under the heat-conducting container 11.

[0055] In this embodiment, considering the actual water adding method of the replenishing water in the heat-conducting container 11, the deoxygenation component 1 of this solution also includes a liquid inlet pipe 12, and the liquid inlet pipe 12 includes a liquid inlet and a liquid outlet, and the horizontal position of the liquid inlet is higher than the horizontal position of the liquid outlet. In the actual installation scenario, the liquid inlet pipe 12 is connected to the internal cavity 111 through the liquid inlet 112 of the heat-conducting container 11, that is, the liquid outlet extends into the cavity 111 of the heat-conducting container 11. Exemplarily, the liquid inlet pipe 12 is sealed to the liquid inlet 112 of the heat-conducting container 11, and the sealing method can be welding or sealing ring assembly connection.

[0056] Considering the composition of the airflow channel in the heat-conducting container 11, at least one side wall of the heat-conducting container 11 has a plurality of air outlets 113, and the air outlets 113 are structural hole features directly formed on the corresponding side wall surface. In this way, each air outlet 113 is connected to the cavity 111 respectively, and a plurality of airflow channels can be formed inside the heat-conducting container 11. The airflow channel here does not belong to the constraint channel of the fixed area, and can adapt to the random flow characteristics of the airflow. The gas molecules have a relatively random flow speed and direction according to the randomness of their own activity. Therefore, the setting of this air outlet 113 can facilitate the diversion of different active gas molecules, but does not affect the flow speed of each gas molecule. The present invention does not limit the shape, size and setting position of the air outlet 113, as long as it can ensure that the oxygen precipitated in the heat-conducting container 11 can flow out to the external environment through the air outlet 113, and the rehydration water in the heat-conducting container 11 will not flow out to the external environment through the air outlet 113. In this way, it can be ensured that the rehydration water will not block the position of the air outlet 113, and thus will not affect the discharge of oxygen. Exemplarily, the air outlet 113 may be any regular shape such as square, circle, trapezoid or polygon, or the air outlet 113 may be an irregular shape, depending on the actual application scenario.

[0057] Further considering the way that the deoxygenated or undeoxygenated replenishing water in the heat-conducting container 11 flows out to the bottom of the heat-conducting container 11 through the liquid flow channel, the liquid in the cavity 111 can flow out to the external environment through the liquid flow channel by means of pressure difference, or the replenishing water can flow out to the external environment through the liquid flow channel by itself under the action of its own weight. The present invention is exemplified by the scheme that the replenishing water flows out to the external environment under the action of its own weight.

[0058] Considering that the replenishing water in the present invention needs to be further deoxygenated after it flows out to the external environment, it is assumed that the replenishing water drips downward through the liquid flow channel under the action of its own weight. During the dripping process, thermal deoxygenation is performed below the heat-conducting container 11 under the action of the upward high-temperature airflow to precipitate oxygen.

[0059] Specifically, the bottom wall of the heat-conducting container 11 has a plurality of liquid balancing holes 114, which can be understood as a plurality of small holes or pores formed on the bottom wall of the heat-conducting container 11. The apertures of the small holes or pores are the same, and the same liquid dripping speed and single dripping amount can be formed under the same pressure and temperature conditions. Alternatively, liquid balancing holes 114 structures with different radial sizes can also be used to adapt to the needs of different scene conditions.

[0060] Exemplarily, each liquid balancing hole 114 is respectively connected to the cavity 111 to form a plurality of liquid flow channels. The liquid balancing hole 114 can be a structural hole feature formed directly on the bottom wall, and the liquid balancing hole 114 is arranged in multiple rows and columns. In this way, each liquid balancing hole 114 is respectively connected to the cavity 111, and multiple liquid flow channels can be formed between the inside of the heat-conducting container 11 and the external environment. The liquid flow channels here do not belong to the constraint channels of the fixed area, and can adapt to the random flow characteristics of the liquid flow. The liquid molecules have a relatively random flow speed and direction according to the randomness of their own activity. Therefore, the setting of this liquid balancing hole 114 can facilitate the diversion of liquid molecules with different activities, but does not affect the flow speed of each liquid molecule. The present invention does not limit the shape, size and setting position of the liquid balancing hole 114, as long as it can ensure that the replenishing water stored in the heat-conducting container 11 can flow out to the external environment through the liquid balancing hole 114, and the oxygen once precipitated in the heat-conducting container 11 will not flow out to the external environment through the liquid balancing hole 114. Exemplarily, the liquid balancing hole 114 may be any regular shape such as square, circle, trapezoid or polygon, or the liquid balancing hole 114 may also be an irregular shape, depending on the actual application scenario.

[0061] Considering that the liquid balancing hole 114 can make the replenishing water form a dripping effect, the diameter of the liquid balancing hole 114 can be constrained to different range values ​​according to different application scenarios of the deoxygenation component 1. For example, taking the application of the deoxygenation component 1 to different steam generators (including evaporative condensers) as an example, the diameter range of the liquid balancing hole 114 is related to the replenishing water amount of the steam generator. For example, in the present invention, the diameter range of the liquid balancing hole 114 can be between 2mm and 10mm, and the endpoint values ​​are included in the scope of this solution. In this way, in functional equipment such as steam generators (evaporative condensers), the liquid balancing hole 114 of the heat conductive container 11 can achieve the effect of replenishing water dripping downward.

[0062] Since the above functions are all realized based on the structure of the heat-conducting container 11 , the specific structural composition of the deoxidation component 1 of the present invention is further limited below in combination with specific examples.

[0063] In this embodiment, the heat-conducting container 11 of the present invention is constructed as a box-like structure, and each side of the box-like structure adopts a heat-conducting plate, and the heat-conducting plate is a plate-like structure made of a heat-conducting material, or the heat-conducting plate here can also be a sheet-like structure made of a heat-conducting material. The box-like structure is used to provide a cavity (111) with a limited spatial size. Exemplarily, the heat-conducting material may include: any one of a metal material, a carbon material and a ceramic material. The thermal conductivity coefficients of the three materials are relatively high, and the thermal conductivity performance of the heat-conducting container 11 in this solution can be better achieved. Correspondingly, the liquid inlet 112 and the gas outlet 113 are arranged on the heat-conducting plates of the corresponding side walls, and the liquid equalization hole 114 is arranged on the heat-conducting plate located on the bottom wall.

[0064] Furthermore, the heat-conducting container 11 is arranged in the upstream area of ​​the high-temperature airflow. The upstream area here refers to the area where the high-temperature airflow flows upward, and the distance between the area and the starting position of the high-temperature airflow is kept within a preset distance. The embodiment of the present disclosure does not limit the preset distance, as long as it can ensure that the temperature of the heat-conducting container 11 can cause the replenishing water to reach a saturated state. The preset distance is determined by the heat dissipation conditions of the actual application scenario.

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

[0066] When the heat-conducting container 11 adopts a detachable structure, the heat-conducting container 11 may include a cover plate 115 located at the top and a box body 116 located at the bottom, and the cover plate 115 is detachably covered on the opening of the box body 116, so that the box body 116 can be easily cleaned by opening the cover plate 115. In addition, the air outlet 113 may be directly formed on the upper area of ​​the side walls of the cover plate 115 and the box body 116, the liquid inlet 112 may be formed on at least one side wall of the box body 116, and the liquid equalization hole 114 may be directly formed on the bottom wall of the box body 116.

[0067] Alternatively, the heat-conducting container 11 may also include a box body 116 located at the top and a bottom plate located below, and the bottom plate can be detachably covered on the opening of the box body 116. In this way, during the production process, the air outlet 113 and the liquid inlet 112 can be directly formed on the side wall and / or top wall of the box body 116, and the liquid equalization hole 114 can be directly formed on the bottom plate.

[0068] In this embodiment, the liquid inlet 112 includes at least one, and the number of the liquid inlet 112 is related to the caliber size of the liquid inlet 112 and the actual amount of liquid inlet, which is not limited in this scheme. The liquid inlet 112 can be set on the cover plate 115 or formed on the side wall of the box body 116. The air outlet 113 can include multiple, and the multiple air outlets 113 are respectively formed on each side wall and / or the cover plate 115 of the box body 116, and are defined as the upper area of ​​each side wall, which can prevent the replenishing water from flowing out of the air outlet 113. Exemplarily, the air outlet 113 can be set on one side wall, two side walls, three side walls or all side walls. The liquid balancing hole 114 can include multiple, and the multiple liquid balancing holes 114 are set on the bottom wall or bottom plate of the box body 116. This scheme does not limit the shape, size and specific position of the liquid inlet 112, the air outlet 113 and the liquid balancing hole 114, which shall be subject to the needs of the actual application scenario.

[0069] When the heat-conducting container 11 adopts an integrally formed box-shaped structure, each side 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, gas outlet 113 and liquid equalizing hole 114 can be molded at one time, which can save process costs.

[0070] Exemplarily, the heat conducting plate constituting the heat conducting container 11 may be a sheet metal structure, and the sheet metal structure may be detachably connected, and the sheet metal structure on either side of the heat conducting container 11 may be set to be a detachable connection. The detachable connection may be any one of threaded assembly, snap-fit, mortise and tenon assembly, plug-in limit or overlap. In this way, the process of forming the heat conducting container 11 can be facilitated, and at the same time, the sheet metal material itself can also be satisfied with thermal conductivity.

[0071] The deoxygenation component 1 of the present invention is used, and a heat-conducting container 11 having heat-conducting properties is used. Heat is conducted to the heat-conducting container 11 in a high-heat environment, and the temperature of the heat-conducting container 11 itself is increased. During the use of the heat-conducting container 11, the liquid to be deoxygenated flows into the cavity 111 through the liquid inlet 112 on one side of the heat-conducting container 11, and the liquid to be deoxygenated is heated twice inside the heat-conducting container 11 to achieve the first deoxygenation, and oxygen is precipitated inside the heat-conducting container 11, and this part of oxygen flows to the external environment through the air flow channel. At this time, the liquid to be deoxygenated stored in the cavity 111 is the liquid to be deoxygenated after the first deoxygenation, and then the liquid to be deoxygenated flows out to the bottom of the heat-conducting container 11 through the liquid flow channel. Afterwards, the liquid to be deoxygenated is deoxygenated for the second time under the action of the high-temperature airflow, and the residual oxygen continues to be precipitated below the heat-conducting container 11. The deoxygenation assembly 1 of the present invention has a compact overall structure, occupies a small space, is easy to assemble, can perform two deoxygenation processes on the deoxygenated liquid, is easy to install in various equipment containers, and is particularly suitable for deoxygenation operations on replenishment water.

[0072] Considering the application of the deoxidation component 1 in the evaporative condensation device 2, the present invention also provides a solution of the evaporative condensation device 2, referring to Figure 1-Figure 6 , the specific structure of the evaporative condensation device 2 equipped with the deoxygenation component 1 is explained.

[0073] The scene condition of the horizontal shell structure adopted by the present invention is that it adopts the type of shell and tube heat exchanger, and the high-temperature refrigerant steam in the heat exchange tube bundle 22 is condensed to heat the desalted water on the outer shell side of the heat exchange tube bundle 22. The desalted water absorbs heat and the temperature rises to obtain high-temperature water vapor.

[0074] Exemplarily, a horizontal shell and tube heat exchanger is used as a steam generator (that is, a condenser, a condensing device). The existing structure includes a shell 21, tube sheets at both ends of the shell 21, water chambers (tube boxes) at both ends, a heat exchange tube bundle 22 in the shell 21, various inlet and outlet pipes, a gas-liquid filter 23, etc.

[0075] Specifically, the evaporative condensing device 2 provided by the present invention includes a shell 21 and the aforementioned deoxygenation component 1. Exemplarily, the shell 21 adopts a tube shell structure. Specifically, a heat exchange tube bundle 22 is arranged in the lower area of ​​the shell 21, and the aforementioned liquid to be deoxygenated (that is, replenishing water) is stored in the lower area of ​​the shell 21, and the heat exchange tube bundle 22 is immersed in the liquid to be deoxygenated; the liquid to be deoxygenated is vaporized in a high temperature state to form an upward high-temperature airflow, and a lateral space for the high-temperature airflow is reserved in the upper area of ​​the shell 21, and the deoxygenation component 1 is installed in the lateral space. Exemplarily, the evaporative condensing device 2 provided by the present invention adopts a horizontal shell and tube structure.

[0076] In this embodiment, the deoxygenation component 1 is installed in the upper area of ​​the heat exchange tube bundle 22 immersed in the liquid to be deoxygenated. Based on the heat release characteristic of the refrigerant liquefaction in the heat exchange tube bundle 22, the tube wall temperature of the heat exchange tube bundle 22 is relatively high. In this way, heat conduction is carried out between the heat exchange tube bundle 22 and the liquid to be deoxygenated, thereby increasing the temperature of the liquid to be deoxygenated until the temperature causes the liquid to be deoxygenated to vaporize and form an upward-flowing high-temperature airflow, that is, high-temperature water vapor, in the upper area of ​​the shell 21 (i.e., the upper area of ​​the shell side). The high-temperature water vapor flows upward and conducts heat with the heat transfer container 11, thereby ensuring that the liquid to be deoxygenated is deoxygenated for the first time inside the cavity 111 of the heat transfer container 11. In addition, the high-temperature water vapor flows upward and can deoxygenate the liquid to be deoxygenated dripping downward through the liquid equalizing hole 114 for the second time.

[0077] At the same time, the area above the heat exchange tube bundle 22 in the evaporative condensing device 2 of the present invention is originally vacant, so that 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 area of ​​the shell, and the high-temperature airflow energy of the high-temperature water vapor produced by the evaporative condensing device 2 itself can also be used. Under the original evaporative heat transfer function, the oxygen content of the replenishing water to be deoxygenated is further reduced, which can avoid oxidation corrosion in the assembly or welding gap between the heat exchange tube bundle 22 in the shell 21 and the corresponding metal structure.

[0078] It should be pointed out that in the entire steam generator system, this condenser is used to produce high-temperature steam from desalted water, so it can also be called a steam generator (that is, an evaporative condensing device 2). In conventional air-conditioning units, the condenser and the evaporator are distinguished based on the phase change state of the refrigerant. For example, the refrigerant condenses in the heat exchanger, so 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 the present invention, the source of heat energy used is the liquefaction heat release of the condensing agent in the heat exchange tube bundle 22, and what is discharged from the shell 21 is water vapor. Therefore, the evaporative condensing device 2 to be protected by the present invention can be called a condenser or an evaporator.

[0079] Considering the outflow of oxygen released from the deoxidizing component 1 in the upper area of ​​the shell side, in order to prevent it from being immersed in the deoxidized liquid again and oxidatively corroding the gaps of the assembly and welding, the evaporative condensing device 2 of the present invention also includes an outlet pipe 25 and a gas-liquid filter 23. Among them, the outlet pipe 25 can facilitate the outflow of oxygen, and the gas-liquid filter 23 can prevent the outflow of discharged water vapor and oxygen-carrying liquid, and can ensure the dryness of the water vapor discharged from the outlet.

[0080] Specifically, the top of the shell 21 is connected to an air outlet pipe 25. 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, the vertical projection of the air outlet pipe 25 relative to the bottom surface of the shell 21 is the second vertical projection area, and the distance between the first vertical projection area and the second vertical projection area is the farthest line segment in the shell 21. In this way, it is ensured that the deoxygenated water flowing out of the device has a sufficiently long path and time in the process of entering the bottom full liquid area (heat exchange tube area) to reduce the phenomenon of air intake and liquid carrying caused by the airflow generated by water evaporation blowing on the liquid deoxygenated water, and further ensure the dryness of the water vapor discharged from the air outlet pipe 25.

[0081] It should be noted that the farthest line segment between the first vertical projection area and the second vertical projection area can be selected from the center point position of each projection area for connection, or, depending on the different shapes of each projection area, the end points or side line positions in the same direction can also be selected for connection.

[0082] Specifically, a gas-liquid filter 23 is disposed in the housing 21, and the gas-liquid filter 23 is horizontally laid above the deoxygenation component 1 and is located below the gas outlet pipe 25. The present invention does not limit the aperture and size of the filter mesh of the gas-liquid filter 23, the number of filter layers, etc., as long as it can block the discharge of liquid water, water vapor and oxygen.

[0083] Exemplarily, the liquid inlet pipe 12 of the deoxygenation component 1 and the liquid replenishment port on the shell 21 can be connected through a flexible hose or a seamless steel pipe, which can facilitate the addition of liquid replenishment water into the heat-conducting container 11 of the deoxygenation component 1.

[0084] Exemplarily, one end of the liquid inlet pipe 12 of the deoxygenation component 1 is assembled and connected with the liquid replenishment port of the shell 21, so that when the liquid replenishment process of the evaporative condensing device 2 is performed, the liquid replenishment water can directly enter the inner cavity 111 of the heat-conducting container 11 of the deoxygenation component 1, which can further ensure that the liquid replenishment water replenished through the liquid replenishment port can all be immersed in the heat exchange area of ​​the shell after deoxygenation. In this way, the oxygen content of the full liquid in the heat exchange area is greatly reduced, which can further alleviate the problem of oxidation corrosion at each metal connection position or metal surface in the shell 21.

[0085] Further, considering the assembly method of the deaerator assembly 1 in the shell 21, the shell 21 is provided with a support plate 24, which is used to support the heat exchange tube bundle 22 in the shell 21. A plurality of support plates 24 are provided, and the deaerator assembly 1 is installed on the support plate 24 located in the shell 21 on the side away from the gas outlet pipe 25. Exemplarily, the support plate 24 is vertically arranged and erected in the shell 21. A plurality of mounting holes are provided through the support plate 24, and each heat exchange tube bundle 22 passes through the corresponding mounting holes, respectively. In this way, a plurality of support plates 24 are arranged at intervals, and can simultaneously bear the weight of the heat exchange tube bundle 22 at different positions.

[0086] Considering the further assembly between the deoxidizing component 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, and the connection here includes any one of welding, threaded assembly, snap connection or plug connection.

[0087] Considering the further assembly between the deoxidizing component 1 and the support plate 24, the solution of the present invention also includes a connector 3, at least part of the structure of the connector 3 is connected to the bottom surface of the heat-conducting container 11, and at least part of the structure of the connector 3 is connected to the top surface or side surface of the support plate 24. The connection here includes any one of welding, threaded assembly, snap connection or plug connection. Exemplarily, the connector 3 uses the same heat-conducting material as the heat-conducting container 11. Exemplarily, the connector 3 and the heat-conducting container 11 are both made of sheet metal. Sheet metal is a part made of metal sheet through stamping, bending, shearing, welding and other processing processes. The commonly used material in the shell and tube is steel, such as carbon steel, stainless steel, galvanized steel plate, etc., which has good processing performance and is cheap. If you want to use a material with a higher thermal conductivity, copper can be used, but the cost is higher.

[0088] Exemplarily, the connecting member 3 is constructed as a plate-like structure, which is convenient for welding or assembly connection with the bottom surface of the heat-conducting container 11 .

[0089] Exemplarily, the connector 3 is constructed as a bending 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] Exemplarily, the connector 3 may be integrally formed with the heat-conducting container 11 , so as to facilitate the assembly of the heat-conducting container 11 relative to the support plate 24 .

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

[0092] The deoxidation component 1 and the evaporative condensation device 2 of the present invention are applied, especially the deoxidation component 1 is added in the upper area of ​​the shell side of the condensation device. For example, the thermal deoxidation component 1 is a square box-shaped structure. Further, the square box-shaped structure is formed by bending and welding a square sheet metal part around, and the upper area of ​​the four walls of the square box-shaped structure is designed with intermittently distributed square outlet pipes 25, and the bottom of the square box-shaped structure is designed with evenly distributed circular liquid holes 114. In addition, the thermal deoxidation component 1 is welded and fixed to the support plate 24 by the connecting member 3. The connecting member 3 can be a bracket. The bracket adopts an L-shaped bracket. The desalted water (that is, the replenishing water, the liquid to be deoxidized) enters the deoxidation component 1 from the liquid inlet pipe 12 on the side of the shell 21. By adding the thermal deoxidation component 1 in the area above the steam generator heat exchange tube bundle 22, oxidation corrosion of the shell 21, the shell and tube, and the connection position with the shell and tube can be avoided, and the system cost and equipment installation space can be reduced.

[0093] In actual application scenarios, desalted water (i.e., replenishing water, water to be deoxygenated) enters the internal space of the thermal deoxygenation component 1, i.e., the cavity 111 of the heat-conducting container 11, from the liquid inlet pipe 12 on the side of the shell 21. The desalted water is uniformly dripped downward through the liquid equalizing hole 114. The steam generated by the evaporation of the full liquid of the heat exchange tube bundle 22 below first heats the desalted water dripping downward (i.e., heat conduction), so that part of the oxygen in the water escapes. Secondly, the steam generated by the evaporation of the heat exchange tube bundle 22 below will contact the flow equalizing plate and the cover plate 115 (i.e., the structures on all sides of the heat-conducting container 11), and transfer the heat to the desalted water stored in the box-like structure, further heating the desalted water (equivalent to secondary heating). The oxygen escaping from the desalted water in the box-like structure gathers above the space inside the heat-conducting container 11 and flows out from the air outlet pipe 25.

[0094] In this way, the desalted water is dripped into the heat exchange area of ​​the heat exchange tube bundle 22 after two thermal deoxidation processes, and heat-exchanges with the high-temperature medium in the tube to produce steam. Oxygen arrives at the shell side outlet pipe 25 through the gas-liquid filter 23 along with the produced steam. The thermal deoxidation component 1 is added above the heat exchange tube bundle 22 to prevent oxygen from contacting the parts of the steam generating device that are prone to oxidation corrosion, such as the connection between the heat exchange tube bundle 22 and the support plate 24 and the tube sheet, where the metal wall temperature is high, the water flow disturbance is severe, and there are many assembly or welding gaps. In addition, the overall structure of the thermal deoxidation component 1 is as far away from the outlet pipe 25 of the steam generator (evaporative condensing device 2) as possible to ensure that the deoxygenated water flowing out of the deoxidation component 1 has enough time to reduce the phenomenon of air intake and liquid carrying caused by the airflow generated by water evaporation blowing on the liquid deoxygenated water during the process of entering the bottom full liquid area (heat exchange tube area), and further ensure the dryness of the water vapor discharged from the outlet pipe 25.

[0095] It should be pointed out that desalted water drips downward from the square box-shaped structure (that is, the bottom surface of the heat-conducting container 11), and water vapor flows upward from the heat exchange tube bundle 22 area. After the water droplets are heated, oxygen overflows. The density of oxygen is smaller than that of water, and it will flow upward with the water vapor, and will not flow downward to contact the support plate 24 and the tube bundle. At the same time, the heat exchange tube bundle 22 area is immersed in desalted water, and the liquid level is slightly higher than the heat exchange tube bundle 22. The water temperature near the liquid surface is higher, and oxygen is difficult to dissolve into the high-temperature water. In this way, the parts of the steam generating device (that is, the evaporative condensing device 2) that are prone to oxidation corrosion are the joints between the heat exchange tube bundle 22 and the support plate 24 and the tube sheet. Here, the metal wall temperature is higher, the water flow disturbance is severe, and there are many assembly or welding gaps. The structure of the present invention allows oxygen to exist only above the liquid level, preventing these parts inside the shell 21 that are prone to oxidation corrosion from contacting oxygen.

[0096] Specifically, the evaporative condensing device 2 of the present invention further includes a high-temperature steam air inlet 26 and a high-temperature steam liquid outlet 27, and both the high-temperature steam air inlet 26 and the high-temperature steam liquid outlet 27 are connected to the shell side of the shell 21. In this way, with the arrangement of the two air inlets and the liquid outlet, the liquid level of the full liquid area where the heat exchange tube bundle 22 is located in the shell 21 can be slightly higher than the top surface of the heat exchange tube bundle 22, so that the metal structure area connected to the heat exchange tube bundle 22 will not contact with the oxygen on the liquid surface and cause corrosion problems.

[0097] Furthermore, the evaporative condensing device 2 of the present invention further comprises pipe boxes on both sides of the shell 21 , and the pipe boxes are connected to the aforementioned high-temperature steam inlet 26 and high-temperature steam outlet 27 .

[0098] In summary, the deoxygenation component 1 provided by the present invention and the evaporative condensing device 2 equipped with the deoxygenation component 1 can simultaneously deoxygenate the replenishment water during the replenishment process of the full liquid in its own shell side. At the same time, it can also utilize the characteristic of the evaporative condensing device 2 itself to produce high-temperature steam, and there is no need to set up additional large deoxygenation equipment outside the evaporative condensing device 2, which can save system costs.
