Description

TECHNICAL FIELD

[0001] The present application relates to the field of steam generator with thermal deoxidization function, in particular to a deoxidization assembly and evaporative condensing device. BACKGROUND

[0002] Horizontal tube full-liquid evaporator is widely used in air conditioning refrigeration, heat pump heating, chemical industry and other fields as a traditional large-capacity evaporator due to its low cost and strong stability. When the evaporator is running, 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 part of the heat exchange tube row), and the heat released by the fluid in the tube is conducted to the liquid outside the tube through the tube wall and fins, and the liquid is phase changed, and the boiling heat exchange generates gas which 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 the tube inside is other heat working medium. The water is heated through the heat exchange tube to become high-temperature steam. In a 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 make-up water is too high, it will cause serious oxidation corrosion to the shell and tube material, and even cause serious accidents. The parts prone to oxidation corrosion in the steam generating device are the connection between the heat exchange tube bundle and the support plate and the tube plate. The metal wall temperature at this position is high, the water flow is turbulent, and there are many assembly or welding gaps. In a boiler system, there are many methods to remove dissolved oxygen in feedwater, such as thermal deoxidization, vacuum deoxidization, chemical deoxidization, and iron rust deoxidization. The principle of thermal deoxidization is based on Henry-Dalton's law, which uses part of the generated steam to heat the feedwater to saturation. At this time, the solubility of oxygen in water is zero, and oxygen is precipitated from water and discharged. The deoxidized water is used to generate steam in the boiler.

[0004] As a steam generating device, the horizontal tube full-liquid evaporator can use part of the generated steam to heat the feedwater. If a separate thermal deoxidizer is set, the system cost and equipment installation space will be increased. CONTENT OF THE INVENTION

[0038] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0039] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of specific examples are described in the following. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0040] For the purpose of description, spatial relative terms can be used in the text to describe the relative position relationship or motion condition of one element or feature with respect to another element or feature as shown in the figure, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "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 is flipped over or the posture is changed or the motion state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship description used in the text will be interpreted accordingly.

[0041] The oxygen removal assembly provided by the present application has a small overall structural device space area, is convenient for thermal oxygen removal of dissolved oxygen liquid inside a large device, can be applied to any application scene requiring thermal oxygen removal, and the specific structure of the present application will be described in detail below by taking the application of the oxygen removal assembly to a condenser as an example.

[0042] The existing condenser of the application is generally divided into air-cooled condenser and water-cooled condenser, wherein the working principle of the air-cooled condenser is that the refrigerant is condensed into liquid state by heat release in the heat exchange tube bundle, and the temperature of the outside air flowing through the heat exchange tube bundle is increased by absorbing heat. The water-cooled condenser is to use the liquid outside the heat exchange tube bundle to absorb heat and increase temperature, and then vaporize into steam. For the water-cooled condenser, the liquid immersed outside the heat exchange tube bundle absorbs the heat released by the refrigerant condensation, and then the temperature of the deoxygenated liquid is increased, and when the temperature is higher than the saturation temperature under the current pressure, it will evaporate into gas state to obtain high-temperature water vapor. In this way, the liquid storage capacity in the water-cooled condenser will gradually decrease, therefore, the water-cooled condenser needs to be replenished to ensure that the liquid in the shell side of the water-cooled condenser can always absorb the heat of the heat exchange tube bundle, thereby ensuring the basic function of the condenser.

[0043] For the case that the condenser needs to be replenished, the replenishment is generally the liquid containing dissolved oxygen. If the dissolved oxygen content in the replenishment is too much, it will cause serious oxidation corrosion to the shell and tube materials of the condenser, and even cause serious accidents. The parts prone to oxidation corrosion in the steam generating device are the connection parts of the heat exchange tube bundle and the support plate and tube plate, where the metal wall surface temperature is high, the water flow is turbulent, and there are many assembly or welding gaps. In the boiler system, there are many methods to remove dissolved oxygen in feedwater, such as thermal deaeration, vacuum deaeration, chemical deaeration, and iron rust deaeration. The principle of thermal deaeration is based on Henry-Dalton theorem, and a part of the generated steam is used to heat the feedwater to saturation state. At this time, the solubility of oxygen in water is zero, and oxygen is precipitated from water and discharged. The water after thermal deaeration can be used to supply the boiler to generate steam.

[0044] The existing deoxygenation assembly has large overall size and occupies more space, and can only be separately arranged outside the condenser. If a separate thermal deaeration device is arranged, the system cost and equipment installation space will be increased.

[0045] In order to alleviate the above problems, the utility model provides a deoxygenation assembly which has small structure size and is convenient to install, and can 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 prepare high-temperature water vapor.

[0046] For example, the steam generator 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 automobile beauty industry. For example, in the food processing industry, the steam generator can be used for heating, sterilization, cooking, etc., to ensure food safety and quality. In the textile industry, steam is used for pretreatment, dyeing, setting, etc., to improve the quality and feel of the fabric. In the pharmaceutical process, steam is used for sterilization, drying, extraction, etc., 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 cooking, bleaching, drying, etc. of raw materials to improve the physical properties of paper. In the heating system, especially in the winter heating system, steam is delivered to each room through pipes to provide warmth for buildings. 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, catering utensils, etc. need to be regularly disinfected with steam at high temperature to kill bacteria and viruses. In agricultural humidification, steam is used to increase air humidity in greenhouse to improve plant growth environment. In automobile beauty, steam is used to clean the surface of the vehicle to remove stains without damaging the paint.

[0047] Further, the specific structure of the steam generator heat pump unit and the conventional air conditioning unit is also four major components including 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 depressurizes the liquid-phase refrigerant condensed from the tube side of the condenser. Then, the throttled and depressurized refrigerant is evaporated into low-temperature and low-pressure gas in the evaporator and enters the suction port of the compressor. Other supporting equipment includes a water pump, an electrical system, a filter, etc.

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

[0049] For example, the structure of the oxygen removal assembly of the present utility model is described in detail in the context of the oxygen removal assembly being applied to the evaporative condenser.

[0050] The oxygen-removing liquid can be desalted water or mixed chemical liquid. The desalted water is also called deionized water or pure water, which is water with most or all ions (such as sodium, calcium, magnesium, chlorine and the like) removed by physical or chemical methods. The desalted water is used to generate water vapor in the equipment. The mixed chemical liquid has different boiling points, and the medium is heated to obtain low-boiling medium steam, so that the physical properties can be separated. The composition of the oxygen-removing liquid is not limited in the utility model, and is subject to the actual application scene.

[0051] As shown in Figures 1-6 The oxygen-removing assembly 1 and the evaporative condensing device 2 provided by the utility model are shown in the drawings. The oxygen-removing assembly 1 comprises a heat-conducting container 11 with a cavity 111. The heat-conducting container 11 can be made of heat-conducting material. 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, so that the heat-conducting container 11 is balanced with the environment temperature. The heat-conducting container 11 has a liquid inlet 112 on one side. The liquid inlet 112 is communicated with the cavity 111 of the heat-conducting container 11. The liquid water (oxygen-removing liquid) flows into the cavity 111 through the liquid inlet 112. The shape, size and position of the liquid inlet 112 are not limited, as long as the liquid water can flow into the cavity 111 through the liquid inlet 112, and the liquid water in the cavity 111 cannot flow out to the external environment through the liquid inlet 112. The liquid inlet 112 can be square, circular, trapezoidal or polygonal, or irregular shape, subject to the actual application scene.

[0052] The oxygen-removing assembly 1 further comprises a liquid flow channel and an air flow channel, which are formed between the cavity 111 and the external environment. The liquid flow channel and the air flow channel can be physical structure channels, such as physical pipeline connection channels, or functional channels, such as the liquid water flowing out of the cavity 111 of the heat-conducting container 11 to the external environment through the liquid flow channel, without the need for physical structure to specify the fixed channel area.

[0053] With the structure as above, the liquid supplement, that is, the liquid to be deoxygenated, flows into the cavity 111 through the liquid inlet 112, and the heat conduction container 11 is placed in a high-temperature environment to form a higher temperature in the cavity 111 through heat conduction. It can be understood that the higher temperature can heat the liquid supplement in the cavity 111 to a saturated state in the secondary heating process of the liquid to be deoxygenated in the heat conduction container 11. In the saturated state, the solubility of oxygen in the liquid supplement is zero, and oxygen is precipitated from the water, thereby forming at least part of the liquid to be deoxygenated in the cavity 111 of the heat conduction container 11 to precipitate oxygen. Since the gas is constantly flowing, the part of the precipitated oxygen flows to the external environment through the gas flow channel, thereby achieving the effect of the first deoxygenation.

[0054] Further, the liquid supplement in the cavity 111 of the heat conduction container 11 is deoxygenated for the first time through the liquid flow channel and flows out below the heat conduction container 11, and is deoxygenated for the second time under the action of the high-temperature gas flow. It should be pointed out that the external environment of the present scheme is set to maintain in the upstream area of the high-temperature gas flow, which can be understood as the area in which the high-temperature gas flow flows upward. In this way, the high-temperature gas flow will continuously act on the heat conduction container 11, which can ensure that the heat conduction container 11 is always in heat exchange with the heat source (that is, the high-temperature gas flow), and further ensure the necessary condition for the first deoxygenation, that is, the heat conduction characteristic of the heat conduction container 11, and the temperature of the heat conduction container 11 is higher than the initial temperature of the liquid supplement in the cavity 111. At the same time, the liquid supplement flowing out through the liquid flow channel can also be heated by heat transfer in the high-temperature gas flow, and then reach a saturated state, in which the solubility of oxygen in the liquid supplement is zero, and the residual oxygen is precipitated again, thereby achieving the effect of the second deoxygenation below the heat conduction container 11.

[0055] In this embodiment, considering the actual water filling mode of the liquid supplement in the heat conduction container 11, the deoxygenation assembly 1 of the present scheme further comprises a liquid inlet pipe 12, the liquid inlet pipe 12 comprising a liquid inlet and a liquid outlet, the horizontal position of the liquid inlet being higher than the horizontal position of the liquid outlet. In the actual installation scene, the liquid inlet pipe 12 communicates with the internal cavity 111 through the liquid inlet 112 of the heat conduction container 11, that is, the liquid outlet extends into the cavity 111 of the heat conduction container 11. Exemplarily, the liquid inlet pipe 12 is sealingly connected with the liquid inlet 112 of the heat conduction container 11, and the sealing mode can adopt welding or sealing ring assembly connection.

[0056] Considering the composition of the air flow 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, which are configured holes formed directly on the corresponding side wall surface, so that each air outlet 113 is in communication with the cavity 111, and a plurality of air flow channels can be formed inside the heat-conducting container 11. The air flow channel here is not a fixed area constraint channel, and can adapt to the random flow characteristics of the air flow. The flow speed and direction of the gas molecules are relatively random according to their own activity, so the arrangement of the air outlet 113 can facilitate the shunting of different active gas molecules, but does not affect the flow speed of each gas molecule. The shape, size and arrangement position of the air outlet 113 are not limited in the utility model, as long as the oxygen gas separated in the heat-conducting container 11 can flow out to the external environment through the air outlet 113, and the liquid water in the heat-conducting container 11 cannot flow out to the external environment through the air outlet 113. In this way, it can be ensured that the liquid water will not block the position of the air outlet 113, and thus will not affect the discharge of oxygen. For example, the air outlet 113 can be any regular shape such as square, circular, trapezoidal or polygonal, or the air outlet 113 can also adopt an irregular shape, which is subject to actual scene application.

[0057] Further considering the way that the liquid water in the heat-conducting container 11 flows out to the lower part 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 pressure difference, or the liquid water can flow out to the external environment by itself under the action of gravity. The utility model takes the scheme that the liquid water flows out to the external environment under the action of gravity as an example.

[0058] Considering that the liquid water flows out to the external environment in the utility model and still needs to be subjected to secondary oxygen removal, the liquid water is set to drip downward through the liquid flow channel under the action of gravity, and in the dripping process, under the action of the high-temperature gas flow flowing upward, thermal oxygen removal is performed below the heat-conducting container 11 to separate oxygen.

[0059] Specifically, the bottom wall of the heat-conducting container 11 has a plurality of liquid equalizing holes 114, which can be understood as a plurality of small holes or fine holes formed in the bottom wall of the heat-conducting container 11. The diameters of the small holes or fine holes 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 equalizing holes 114 structures with different radial sizes can be used to adapt to the needs of different scene conditions.

[0060] Exemplarily, each liquid equalizing hole 114 is in communication with the cavity 111, forming a plurality of liquid flow channels. The liquid equalizing hole 114 can be a directly formed configuration hole feature on the bottom wall, and the liquid equalizing holes 114 are arranged in multiple rows and columns. In this way, each liquid equalizing hole 114 is in communication with the cavity 111, and a plurality of liquid flow channels can be formed between the inside of the heat conduction container 11 and the external environment. Here, the liquid flow channels are not fixed-area constraint channels, and can adapt to the random flow characteristics of the liquid flow. The flow speed and direction of the liquid molecules are relatively random according to the randomness of their activity. Therefore, the arrangement of the liquid equalizing hole 114 can facilitate the flow splitting of different active liquid molecules, but does not affect the flow speed of each liquid molecule. The shape, size and arrangement position of the liquid equalizing hole 114 are not limited in the present application, as long as the liquid supplement water stored in the heat conduction container 11 can flow out of the liquid equalizing hole 114 to the external environment, and the oxygen gas once separated in the heat conduction container 11 cannot flow out of the liquid equalizing hole 114 to the external environment. Exemplarily, the liquid equalizing hole 114 can be any regular shape such as a square, a circle, a trapezoid or a polygon, or the liquid equalizing hole 114 can also adopt an irregular shape, which is subject to actual scene application.

[0061] Considering that the liquid equalizing hole 114 can form a dripping effect for the liquid supplement water, the diameter of the liquid equalizing hole 114 can be constrained within different ranges according to different application scenarios of the oxygen removal assembly 1. Exemplarily, taking the application of the oxygen removal assembly 1 in different steam generators (including evaporative condensers) as an example, the diameter range of the liquid equalizing hole 114 is related to the amount of liquid supplement water of the steam generator. Exemplarily, the diameter range of the liquid equalizing hole 114 in the present application can be between 2 mm and 10 mm, and the end point value is included in the range of the present application. In this way, in functional devices such as steam generators (evaporative condensers), the liquid equalizing hole 114 of the heat conduction container 11 can achieve the effect of downward dripping of the liquid supplement water.

[0062] Based on the above functional implementation, which is all implemented according to the structure of the heat conduction container 11, the specific structure of the oxygen removal assembly 1 of the present application is further limited in combination with specific examples.

[0063] In this embodiment, the heat conduction container 11 of the present application is configured as a box-shaped structure, and the heat conduction plates are used on each side of the box-shaped structure. The heat conduction plate is a plate-shaped structure made of a heat conduction material, or the heat conduction plate can also be a sheet-shaped structure made of a heat conduction material. The box-shaped structure is used to provide a cavity (111) with a limited space size. Exemplarily, the heat conduction material can include any one of a metal material, a carbon material and a ceramic material, and the heat conduction coefficients of the three materials are relatively high, which can better achieve the heat conduction performance of the heat conduction container 11 in the present application. Correspondingly, the liquid inlet 112 and the gas outlet 113 are arranged on the heat conduction plates of the corresponding side walls, and the liquid equalizing hole 114 is arranged on the heat conduction plate located on the bottom wall.

[0064] Further, the heat-conducting container 11 is arranged in an upstream region of the high-temperature gas flow. The upstream region here refers to a region where the high-temperature gas flow flows upward, and the distance from the starting position of the high-temperature gas flow is kept within a preset distance. The present disclosure does not limit the preset distance, as long as the temperature of the heat-conducting container 11 can promote the saturation of the liquid supplement water. The preset distance is determined according to the heat dissipation of the actual application scenario.

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

[0066] When the heat-conducting container 11 is in a detachable structure, the heat-conducting container 11 can include a cover plate 115 at the top and a box body 116 below. The cover plate 115 is detachably closed at the opening of the box body 116. In this way, the cover plate 115 can be opened to facilitate cleaning of the box body 116. In addition, the gas outlet 113 can be directly formed on the upper region of the side wall of the cover plate 115 and the box body 116. The liquid inlet 112 can be formed in at least one side wall of the box body 116. The liquid distribution hole 114 can be directly formed on the bottom wall of the box body 116.

[0067] Alternatively, the heat-conducting container 11 can include a box body 116 at the top and a bottom plate below. The bottom plate is detachably closed at the opening of the box body 116. In this way, the gas outlet 113 and the liquid inlet 112 can be directly formed on the side wall and / or the top wall of the box body 116 during the process of producing the box body 116. The liquid distribution 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 liquid inlet amount. The present solution does not limit it. The liquid inlet 112 can be arranged on the cover plate 115 or formed on the side wall of the box body 116. The gas outlet 113 can include multiple, and the multiple gas outlets 113 are respectively formed on each side wall of the box body 116 and / or the cover plate 115, and are limited to the upper region of each side wall, so as to avoid the liquid supplement water flowing out of the gas outlet 113. For example, the gas outlet 113 can be arranged on one side wall, two side walls, three side walls, or all side walls. The liquid distribution hole 114 can include multiple, and the multiple liquid distribution holes 114 are arranged on the bottom wall of the box body 116 or the bottom plate. The present solution does not limit the shape, size, and specific position of the liquid inlet 112, the gas outlet 113, and the liquid distribution hole 114, and is subject to the requirements 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. The liquid inlet 112, the gas outlet 113, and the liquid distribution hole 114 can be formed at one time during the forming process of the box-shaped structure, which can save the process cost.

[0070] Exemplarily, the heat-conducting plate constituting the heat-conducting container 11 can adopt a sheet metal structure, which can adopt a detachable connection mode, and any side sheet metal structure constituting the heat-conducting container 11 can be arranged in a detachable connection mode. The detachable connection can adopt any one of threaded assembly, buckle clamping, mortise and tenon assembly, plug-in limiting or lapping. In this way, the process forming of the heat-conducting container 11 can be facilitated, and meanwhile, the heat-conducting performance of the sheet metal material itself can be met.

[0071] The oxygen removal assembly 1 of the utility model is applied to the heat-conducting container 11 with heat-conducting performance, heat conduction is carried out on the heat-conducting container 11 in a high-temperature environment, and the temperature of the heat-conducting container 11 itself is increased. In the application process of the heat-conducting container 11, the oxygen removal liquid flows into the cavity 111 through the liquid inlet 112 on one side of the heat-conducting container 11, the oxygen removal liquid is heated again in the heat-conducting container 11, the first oxygen removal is realized, and oxygen is separated out in the heat-conducting container 11, and the oxygen is flowed to the external environment through the airflow channel. At this time, the oxygen removal liquid stored in the cavity 111 is the oxygen removal liquid after the first oxygen removal, and then the oxygen removal liquid flows out to the lower side of the heat-conducting container 11 through the liquid flow channel. Then, the oxygen removal liquid is subjected to the second oxygen removal under the action of the high-temperature airflow, and the residual oxygen is continuously separated out below the heat-conducting container 11. The oxygen removal assembly 1 of the utility model has the advantages of compact overall structure, small space occupation, convenient assembly, twice oxygen removal process for the oxygen removal liquid, convenient installation in various equipment containers, and especially suitable for oxygen removal operation of the liquid supplementing water.

[0072] Considering the application of the oxygen removal assembly 1 in the evaporative condensing device 2, the utility model also provides a scheme of the evaporative condensing device 2, which is referred to as Figures 1-6 The specific structure of the evaporative condensing device 2 provided with the oxygen removal assembly 1 is described.

[0073] The scene condition of the horizontal shell structure adopted by the utility model is that the shell and tube heat exchanger is adopted, the high-temperature refrigerant steam in the heat exchange tube bundle 22 is condensed, the desalted water outside the shell of the heat exchange tube bundle 22 is heated, and the desalted water absorbs heat to obtain high-temperature water vapor.

[0074] Exemplarily, the horizontal shell and tube heat exchanger is adopted as the steam generator (that is, the condenser and the condensing device), and the existing structure includes the shell 21, the tube plate at both ends of the shell 21, the water chamber (pipe box) at both ends, the heat exchange tube bundle 22 in the shell 21, various inlet and outlet connecting pipes, the gas-liquid filter screen 23 and the like.

[0075] Specifically, the evaporative condenser 2 provided by the utility model includes a shell 21 and the aforementioned oxygen removal assembly 1, and the shell 21 adopts a shell-and-tube structure. Specifically, the shell 21 is provided with a heat exchange tube bundle 22 in the lower region, and the shell 21 stores the aforementioned oxygen removal liquid (i.e. make-up water) in the lower region, and the heat exchange tube bundle 22 is immersed in the oxygen removal liquid; the oxygen removal liquid is gasified to form an upward high-temperature gas flow in a high-temperature state, and the shell 21 is provided with a transverse space in the upper region for the high-temperature gas flow to flow, and the oxygen removal assembly 1 is installed in the transverse space. Specifically, the evaporative condenser 2 provided by the utility model adopts a horizontal shell-and-tube structure.

[0076] In the embodiment, the oxygen removal assembly 1 is installed above the heat exchange tube bundle 22 immersed in the oxygen removal liquid, and based on the heat release characteristics of the refrigerant liquidized in the heat exchange tube bundle 22, the temperature of the tube wall of the heat exchange tube bundle 22 is relatively high, so that heat conduction is performed between the heat exchange tube bundle 22 and the oxygen removal liquid, thereby improving the temperature of the oxygen removal liquid, until the temperature causes the oxygen removal liquid to be gasified and form an upward high-temperature gas flow, i.e. high-temperature water vapor, in the upper region of the shell 21 (i.e. the upper region of the shell side), and the high-temperature water vapor flows upward and performs heat conduction with the heat conduction container 11, thereby ensuring that the oxygen removal liquid is subjected to first oxygen removal in the cavity 111 of the heat conduction container 11, and in addition, the upward flow of the high-temperature water vapor can perform second oxygen removal on the oxygen removal liquid dropped downward through the liquid equalizing hole 114.

[0077] Meanwhile, the upper region of the heat exchange tube bundle 22 in the evaporative condenser 2 is in an idle state, so that the oxygen removal assembly 1 can be installed in the space in the shell 21, i.e. the oxygen removal assembly 1 is installed in the upper region of the shell side, and the high-temperature gas flow energy of the high-temperature water vapor generated by the evaporative condenser 2 itself can be applied, so that the oxygen content of the make-up water of the oxygen removal water is further reduced under the original evaporative heat transfer function, and the assembly or welding gap between the heat exchange tube bundle 22 and the corresponding metal structure in the shell 21 can be prevented from being oxidized and corroded.

[0078] It should be noted that in the entire steam generator system, the condenser is also used to generate high-temperature steam of desalted water, so it can also be called a steam generator (i.e. the evaporative condenser 2). In a conventional air conditioning unit, the condenser and the evaporator are distinguished according to the phase change state of the refrigerant, for example, the refrigerant is condensed in the heat exchanger, so this component is a condenser; if the refrigerant is evaporated in the heat exchanger, this component is an evaporator. Corresponding to the evaporative condenser 2 of the utility model, the heat energy source applied is the heat release of the condensate liquidized in the heat exchange tube bundle 22, and the water vapor is discharged from the shell 21, so the evaporative condenser 2 to be protected by the utility model can be called a condenser or an evaporator.

[0079] The evaporative condenser 2 of the utility model further comprises an air outlet pipe 25 and a gas-liquid filter screen 23, in order to avoid the outflow of oxygen gas from the upper region of the shell side, so as to avoid the oxygen gas from being immersed in the liquid to be deoxygenated again and oxidizing and corroding the gaps of the assembly and welding.

[0080] Specifically, the top of the shell 21 is communicated with an air outlet pipe 25, along the height direction of the shell 21, the vertical projection of the deoxygenation assembly 1 relative to the bottom surface of the shell 21 is a first vertical projection area, the vertical projection of the air outlet pipe 25 relative to the bottom surface of the shell 21 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 21. In this way, the deoxygenated water flowing out of the device has a long enough path and time to reduce the suction of liquid deoxygenated water caused by the blowing of the gas flow generated by water evaporation during the process of entering the bottom full-liquid area (heat exchange pipe area), thereby further ensuring 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 connected by selecting the center point positions of the projection areas. Alternatively, according to the different shapes of the projection areas, the end points or edge lines in the same direction can also be selected for connection.

[0082] Specifically, the gas-liquid filter screen 23 is arranged in the shell 21, the gas-liquid filter screen 23 is horizontally laid above the deoxygenation assembly 1 and below the air outlet pipe 25. The utility model does not limit the aperture and size of the filter screen holes of the gas-liquid filter screen 23, the number of filter screen layers, etc., as long as the liquid water can be blocked together with the discharge of water vapor and oxygen.

[0083] For example, the liquid inlet pipe 12 of the deoxygenation assembly 1 and the liquid supplementing opening on the shell 21 can be communicated through a flexible hose or a seamless steel pipe, so that the supplementing water can be added to the heat-conducting container 11 of the deoxygenation assembly 1.

[0084] For example, one end of the liquid inlet pipe 12 of the deoxygenation assembly 1 is assembled with and communicated with the liquid supplementing opening of the shell 21, so that when the liquid supplementing process of the evaporative condenser 2 is performed, the supplementing water can directly enter the inner cavity 111 of the heat-conducting container 11 of the deoxygenation assembly 1, and it can be further ensured that the supplementing water supplemented through the liquid supplementing opening can all be immersed in the heat exchange region of the shell side after deoxygenation. In this way, the oxygen content of the full-liquid in the heat exchange region is greatly reduced, and the problem of oxidation and corrosion of the metal connection positions or metal surfaces in the shell 21 can be further alleviated.

[0085] Further, considering the assembly of the oxygen removal assembly 1 in the shell 21, the existing support plate 24 is provided in the shell 21, and the support plate 24 is used to support the heat exchange tube bundle 22 in the shell 21. The support plate 24 is provided in multiple, and the oxygen removal assembly 1 is installed on the support plate 24 located away from the gas outlet pipe 25 in the shell 21. Exemplarily, the support plate 24 is vertically arranged and vertically arranged in the shell 21. The support plate 24 is provided with a plurality of mounting holes, and each heat exchange tube bundle 22 passes through a corresponding mounting hole. In this way, the 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 oxygen removal assembly 1 and the support plate 24, the bottom surface of the heat conduction container 11 can be directly connected with the top surface of the support plate 24. The connection here includes any one of welding, threaded assembly, clamping connection or plug-in connection.

[0087] Considering the further assembly between the oxygen removal assembly 1 and the support plate 24, the scheme of the utility model further includes a connecting piece 3, which is at least partially connected in structure to the bottom surface of the heat conduction container 11, and is at least partially connected in structure to the top surface or side surface of the support plate 24. The connection here includes any one of welding, threaded assembly, clamping connection or plug-in connection. Exemplarily, the connecting piece 3 is made of the same heat conduction material as the heat conduction container 11. Exemplarily, the connecting piece 3 and the heat conduction container 11 are both made of sheet metal. Sheet metal is a part made of metal plate through stamping, bending, shearing and welding processes. The commonly used material in the shell pipe is steel, such as carbon steel, stainless steel, galvanized steel plate and the like. It has good processing performance and is cheap. If a material with higher thermal conductivity is used, copper can be used, but the cost is higher.

[0088] Exemplarily, the connecting piece 3 is configured as a plate structure, which is convenient for welding or assembly connection with the bottom surface of the heat conduction container 11.

[0089] Exemplarily, the connecting piece 3 is configured as a bent structure, one side of which is convenient for welding or assembly connection with the bottom surface of the heat conduction container 11, and the other side of which is convenient for welding or assembly connection with the support plate 24.

[0090] Exemplarily, the connecting piece 3 can be integrally formed with the heat conduction container 11. In this way, the assembly between the heat conduction container 11 and the support plate 24 can be facilitated.

[0091] Exemplarily, the connection between the connecting piece 3 and the support plate 24 adopts detachable connection. The detachable connection here includes any one of threaded assembly, clamping connection or plug-in connection.

[0092] The oxygen removal assembly 1 and the evaporative condensing device 2 have the following advantages: the oxygen removal assembly 1 is arranged on the upper region of the shell side of the condensing device, the heat transfer container 11 is in the form of a square box, the square box structure is formed by bending and welding around a square sheet metal part, square gas outlet pipes 25 are arranged on the upper region of the square box structure, circular liquid distribution holes 114 are arranged on the bottom of the square box structure, the heat transfer container 11 is fixed to the support plate 24 through the connecting piece 3, the connecting piece 3 can be a bracket, the bracket is in the form of an L-shaped bracket, and the desalted water (i.e. the liquid supplement water and the water to be deoxygenated) enters the oxygen removal assembly 1 from the liquid inlet pipe 12 on the side of the shell 21.

[0093] In actual application scenarios, the desalted water (i.e. the liquid supplement water and the water to be deoxygenated) enters the internal space of the heat transfer container 11 from the liquid inlet pipe 12 on the side of the shell 21, that is, the cavity 111 of the heat transfer container 11, the desalted water realizes uniform downward dripping through the liquid distribution holes 114, the steam generated by the full-liquid evaporation of the lower heat exchange tube bundle 22 is immersed, the desalted water is heated (i.e. heat conduction) first, part of the oxygen in the water escapes, secondly, the steam generated by the evaporation of the lower heat exchange tube bundle 22 contacts the flow distribution plate and the cover plate 115 (i.e. the surface structure of the heat transfer container 11), and the heat is transferred to the desalted water stored in the box structure, further heating (equivalent to secondary heating) the desalted water, the oxygen escaped from the desalted water in the box structure is gathered above the internal space of the heat transfer container 11 and flows out through the gas outlet pipe 25.

[0094] In this way, the desalted water drips onto the heat exchange region of the heat exchange tube bundle 22 after being deoxygenated twice, exchanges heat with the high-temperature medium in the tube to generate steam, and the oxygen escapes with the generated steam through the gas-liquid filter screen 23 to the gas outlet pipe 25 of the shell side. The heat transfer container 11 is arranged above the heat exchange tube bundle 22, which can avoid the oxygen from contacting the parts prone to oxidation and corrosion in the steam generation device, such as the connection between the heat exchange tube bundle 22 and the support plate 24 and the tube plate, where the metal wall surface has a high temperature, the water flow is turbulent, and there are many assembly or welding gaps. In addition, the heat transfer container 11 is arranged as far as possible from the gas outlet pipe 25 of the steam generator (evaporative condensing device 2), so that the deoxygenated water flowing out of the heat transfer container 11 has enough time to reduce the liquid entrainment phenomenon caused by the blowing of the gas flow generated by the evaporation of the water to the liquid deoxygenated water when the deoxygenated water enters the bottom full-liquid region (heat exchange tube region), further ensuring the dryness of the water vapor discharged from the gas outlet pipe 25.

[0095] It should be pointed out that, in addition to salt water from the square box structure (that is, the heat conduction container 11 bottom surface) downward drip, water vapor from the heat exchange tube bundle 22 area flows upward, water droplets are heated after oxygen overflow, the density of oxygen is smaller than water, and will flow upward with 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 the desalted water, and the liquid level is slightly higher than the heat exchange tube bundle 22, and the water temperature is higher near the liquid level, and it is difficult for oxygen to dissolve into the high-temperature water. In this way, the steam generating device (that is, the evaporative condensing device 2) is easy to occur in the heat exchange tube bundle 22 and the support plate 24, the tube plate connection part, the metal wall surface temperature is higher, the water flow is disturbed violently, and there are more assembly or welding gaps, and the structure of the utility model makes oxygen only exist above the liquid level, avoiding the shell 21 inside these easy oxidation corrosion parts contact oxygen.

[0096] Specifically, the evaporative condensing device 2 of the utility model further comprises a high-temperature steam inlet 26 and a high-temperature steam outlet 27, and the high-temperature steam inlet 26 and the high-temperature steam outlet 27 are in communication with the shell side of the shell 21. In this way, under the setting of the two inlets and the outlet, the liquid level height of the full-liquid area of the heat exchange tube bundle 22 in the shell 21 is slightly higher than the top surface of the heat exchange tube bundle 22, so that the metal structure area connected with the heat exchange tube bundle 22 will not be corroded by contacting oxygen on the liquid level.

[0097] Further, the evaporative condensing device 2 of the utility model further comprises a tube box on both sides of the shell 21, and the tube box is in communication with the high-temperature steam inlet 26 and the high-temperature steam outlet 27.

[0098] In summary, the oxygen removal assembly 1 and the evaporative condensing device 2 provided by the utility model can simultaneously remove oxygen from the liquid supplementing water in the full-liquid in the shell side of the oxygen removal assembly 1, and can also utilize the characteristics of the high-temperature steam generated by the evaporative condensing device 2, without the need for additional large oxygen removal equipment outside the evaporative condensing device 2, thereby saving system cost.
