Description

Technical Field

[0001] The utility model relates to the technical field of thermal deoxidation, in particular to a deoxidation device and a steam generator having the same. Background Art

[0002] As a traditional large-capacity evaporator, the horizontal tube flooded evaporator is widely used in air conditioning, heat pump heating, chemical engineering, 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 tubes (the liquid level is usually slightly higher than the highest point of the heat exchange tube row). The heat released by the fluid in the tubes is transferred to the liquid outside the tubes through the tube walls and fins, causing the liquid to undergo a phase change. The gas generated by the boiling heat exchange is discharged from the top of the heat exchanger.

[0003] If a horizontal, flooded-tube evaporator is used as a steam generator, the shell-side space outside the heat exchange tubes contains boiling water, while the interior of the tubes contains other hot working fluids. The heat exchange tubes heat the water, turning it into high-temperature steam. In a high-temperature steam heat pump unit, the steam generator directly generates steam, and its durability is closely linked to the quality of the water within the shell. Excessive dissolved oxygen in the feed water can cause severe oxidative corrosion of the shell and tube materials, and even lead to serious accidents. In boiler systems, various methods exist to remove dissolved oxygen from the feed water, including thermal deoxygenation, vacuum deoxygenation, chemical deoxygenation, and rust deoxygenation. Thermal deoxygenation is based on the Henry-Dalton theorem, utilizing a portion of the produced steam to heat the feed water to saturation. At this point, the solubility of oxygen in the water is zero, and oxygen is subsequently released from the water and discharged. The deoxygenated water is then fed to the boiler to generate steam.

[0004] Most existing thermal deaerators are separately installed on the deaeration piping system or outside the steam generating device, which not only takes up installation space, but also increases the complexity of the piping system and increases production costs. Utility Model Content

[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] As mentioned in the background technology, in the existing deoxygenation equipment, most of them are equipped with a separate deoxygenation pipeline system, and a deoxygenation device is installed on the pipeline system to carry out the deoxygenation process. However, such an arrangement increases the complexity of the pipeline system structure and occupies installation space. Therefore, in order to solve the above technical problems, the deoxygenation device of the present application is directly arranged in the steam generating chamber 110, and the deoxygenation device includes a mixing component 200. The liquid to be deoxygenated enters the mixing component 200 through a first port 201, and the first heated gas enters the mixing component 200 through a second port 202. The first heated gas and the liquid to be deoxygenated can be quickly and fully mixed in the mixing component. After the first heated gas heats the liquid to be deoxygenated, the oxygen in the liquid to be deoxygenated is precipitated. Thereafter, the oxygen flows out from the first port 201, and the deoxygenated liquid falls directly into the steam generating chamber 110 through the second port 202. There is no need for a complex pipeline design, which saves equipment installation space and reduces costs.

[0048] Please refer to Figures 1 to 15 The present application provides a deoxygenation device, which is arranged in a steam generating chamber 110 of a target workpiece 100, and the deoxygenation device includes: a flow mixing component 200, which is arranged in the steam generating chamber 110, and the flow mixing component 200 includes a first port 201 and a second port 202 arranged opposite to each other in a vertical direction, the first port 201 is used to discharge gas, and the second port 202 is used to pass a first heating vapor, and the second port 202 is connected to the steam generating chamber 110; the flow mixing component 200 is also provided with a liquid inlet 210, and the liquid inlet 210 is located at one end of the flow mixing component 200 close to the first port 201, and the liquid inlet 210 is used to pass a liquid to be deoxygenated into the flow mixing component 200, so that the first heating vapor mixes with the liquid to be deoxygenated and heats the liquid to be deoxygenated during the process of flowing upward in the flow mixing component 200, thereby deoxygenating the liquid to be deoxygenated.

[0049] According to the deoxygenation device of the present application, it is arranged in the steam generating chamber 110 of the target workpiece 100, wherein the deoxygenation device includes a flow mixing component 200, which is arranged in the steam generating chamber 110, and the flow mixing component 200 includes a first port 201 and a second port 202 arranged opposite to each other in a vertical direction, the first port 201 is used to discharge gas, and the second port 202 is used to pass the first heating vapor, and the second port 202 is connected to the steam generating chamber 110; the flow mixing component 200 is also provided with a liquid inlet 210, the liquid inlet 210 is located at one end of the flow mixing component 200 close to the first port 201, and the liquid inlet 210 is used to pass the liquid to be deoxygenated into the flow mixing component 200, so that the first heating vapor is mixed with the liquid to be deoxygenated and heats the liquid to be deoxygenated during the process of flowing upward in the flow mixing component 200, thereby deoxygenating the liquid to be deoxygenated. With this arrangement, the liquid to be deoxygenated flows downward along the flow mixing component 200 under the action of its own gravity, and the first heating gas, due to its lighter weight, flows from bottom to top along the flow mixing component 200, and then the first heating gas and the liquid to be deoxygenated are mixed in the flow mixing component 200. At the same time, the first heating gas heats the liquid to be deoxygenated, so that the oxygen in the liquid to be deoxygenated is precipitated, and the deoxygenated liquid directly falls into the steam generating chamber 110 through the second port 202, and the oxygen is directly discharged through the first port 201. There is no need to set a separate deoxygenation pipeline outside the target workpiece 100, so that the deoxygenated liquid directly participates in the steam generation reaction in the steam generating chamber 110, the overall structure is simpler, and installation space is saved.

[0050] Specifically, the flow mixing component 200 also includes a heating section 220, which is located between the liquid inlet 210 and the second port 202. The deoxygenation device also includes a heating chamber 300, at least partially disposed within the heating section 220. The heating chamber 300 is used to introduce a second heating medium to heat the liquid to be deoxygenated within the heating section 220. The provision of the heating chamber 300 allows the second heating medium to exchange heat with the flow mixing component 200, further heating the liquid to be deoxygenated, achieving dual heating and significantly improving the deoxygenation efficiency and speed. Furthermore, the design of the heating chamber 300 reduces heat loss during the heat transfer process because the second heating medium directly acts on the flow mixing component 200, avoiding heat loss caused by additional heat transfer media or pipes, thereby improving the overall thermal efficiency of the system. The placement of the heating section 220 between the liquid inlet 210 and the second port 202 prevents the liquid to be deoxygenated from flowing into the heating chamber 300 and causing liquid overflow.

[0051] like Figure 3As shown, the flow mixing component 200 also includes a liquid inlet section 230, which is connected to the heating section 220, and the first port 201 is arranged at one end of the liquid inlet section 230 away from the heating section 220, and the liquid inlet portion 210 is arranged on the liquid inlet section 230; the deoxygenation device also includes: a liquid inlet chamber 400, which is used to pass the liquid to be deoxygenated, the liquid inlet chamber 400 is arranged above the heating chamber 300, at least a portion of the liquid inlet section 230 is arranged in the liquid inlet chamber 400, and the liquid inlet portion 210 is connected to the liquid inlet chamber 400.

[0052] The liquid inlet section 230 is connected to the heating section 220, and the first port 201 is arranged at the far end of the liquid inlet section 230. This allows the liquid to be deoxygenated to flow smoothly along a predetermined path before entering the mixing component 200, avoiding direct impact on the heating section, thereby improving the preheating uniformity and heating efficiency of the liquid. The first port 201 is located at the top of the liquid inlet section 230, which helps prevent the heated vapor from flowing back from the liquid inlet 210, ensuring the unidirectional flow of gas and liquid in the mixing component, and improving the stability and safety of the system. The independent design of the liquid inlet chamber 400 and the heating chamber 300 allows the operator to adjust the medium parameters (such as temperature, pressure, etc.) in the two chambers separately to adapt to different working conditions and needs, thereby improving the adaptability and operational flexibility of the deoxygenation device. By designing the liquid inlet chamber 400 above the heating chamber 300, the deoxygenation device can be compactly arranged in the vertical direction, reducing the footprint of the equipment. The direct connection between the liquid inlet part 210 and the liquid inlet chamber 400 simplifies the liquid introduction path in the system, reduces the connecting pipes and accessories, and reduces the complexity of the system. It also helps to reduce potential leakage points and enhance the overall sealing and reliability of the system.

[0053] During specific implementation, the deoxygenation device further includes: a first baffle 410, which is provided with a first through-hole 411; a second baffle 420, which is disposed below and spaced apart from the first baffle 410; a liquid inlet chamber 400 disposed between the first baffle 410 and the second baffle 420; a second through-hole 421 disposed on the second baffle 420, which is opposite to the first through-hole 411; and a flow mixing component 200 sequentially passing through the first through-hole 411 and the second through-hole 421. The first baffle 410 and the second baffle 420 form the liquid inlet chamber 400. The positioning of the first baffle 410 and the second baffle 420 through the first through-hole 411 and the second through-hole 421 effectively enhances the structural stability of the flow mixing component 200 in the steam generator, prevents positional displacement or damage due to vibration or fluid impact, and improves the reliability and service life of the equipment. The spacing design of the first partition 410 and the second partition 420 forms a relatively closed space, which helps to optimize the heat distribution in the heating chamber 300 and the liquid inlet chamber 400. The structure of the partition also helps to prevent unnecessary mixing between the heating medium and the liquid to be deoxygenated.

[0054] like Figure 2 and Figure 14 As shown, the deoxygenation device further includes a liquid inlet pipe 430 disposed within the liquid inlet chamber 400. The liquid inlet pipe 430 is provided with a plurality of liquid outlet holes 431, which are spaced apart along the extension direction of the liquid inlet pipe 430 and each of which is in communication with the liquid inlet chamber 400. The plurality of liquid outlet holes 431 are spaced apart along the extension direction of the liquid inlet pipe 430 to ensure that the liquid to be deoxygenated is evenly distributed throughout the entire chamber space upon entering the liquid inlet chamber 400. This even distribution of the liquid allows the heat of the second heating medium to be more fully utilized, thereby avoiding heat waste, reducing energy consumption, improving energy efficiency, and preventing local overheating or overcooling. This improves the uniformity and preheating effect of the liquid in contact with the second heating medium. By providing the plurality of liquid outlet holes on the liquid inlet pipe, the liquid to be deoxygenated enters the liquid inlet chamber 400 in a dispersed stream, increasing the contact area and contact opportunities between the liquid and the heating medium, thereby significantly enhancing heat exchange efficiency and accelerating the preheating and deoxygenation process of the liquid. Compared with directly introducing the liquid into the heating chamber, the provision of the liquid inlet pipe 430 and multiple liquid outlet holes 431 can reduce the direct impact of the deoxygenated liquid on the mixing component 200 and the heating section 220, reduce the equipment vibration and noise caused by liquid impact, and improve the stability of the equipment and the comfort of the working environment.

[0055] Furthermore, the deoxygenation device also includes a third baffle 310, disposed below and spaced apart from the second baffle 420. The heating chamber 300 is disposed between the second baffle 420 and the third baffle 310. The third baffle 310 is provided with a third through hole 311. The end of the flow mixing component 200 away from the first baffle 410 is passed through the third through hole 311 and connected to the third baffle 310. The location of the heating chamber 300 between the second baffle 420 and the third baffle 310 ensures close contact between the heating chamber and the heating section 220 of the flow mixing component 200, thereby improving heat exchange efficiency. Furthermore, the positioning of the heating chamber allows for better control of the flow direction and distribution of the heating medium, thereby avoiding heat waste. The third baffle 310, spaced apart from the second baffle 420, provides stable support for the heating chamber 300. The third through-hole 311 in the third baffle 310 is used to secure the flow mixing component 200. This enhances the overall structural stability and mechanical strength of the deaerator, reducing the risk of damage from vibration or thermal expansion and contraction during operation. The third baffle 310, in conjunction with the second baffle 420, creates a closed heating environment, helping to reduce heat loss and maintain the internal temperature of the heating chamber 300, thereby improving overall energy efficiency.

[0056] In this application, if Figure 5 As shown, the deaerator further includes: a support plate 320, on which a steam inlet channel 321 and a steam outlet channel 322 are provided; a baffle 330, disposed opposite and spaced from the support plate 320, with the heating chamber 300 disposed between the support plate 320 and the baffle 330; a first flow guide channel 340, disposed within the heating chamber 300, extending in a zigzag trajectory, with its ends communicating with the steam inlet channel 321 and the steam outlet channel 322, respectively; and a plurality of flow mixing components 200, spaced sequentially along the extension direction of the first flow guide channel 340. The steam inlet channel 321 and steam outlet channel 322 provided on the support plate 320, and the associated baffle 330, form the heating chamber 300. This design ensures a more uniform distribution of the second heating medium within the heating chamber 300, preventing local overheating and improving thermal energy utilization efficiency and the consistency of the deoxygenation effect. The design of the zigzag-shaped first flow guide channel 340 increases the contact area and contact time between the heating medium and the flow mixing component 200, thereby improving heat exchange efficiency. The extended path of the zigzag trajectory enables the heating medium to fully heat the flow mixing component 200, ensuring that the deoxygenated liquid receives sufficient heat to promote the escape of oxygen as it passes through the flow mixing component 200. The provision of the support plate 320 and baffle 330 not only provides stable support for the flow mixing component 200 but also enhances the structural stability and durability of the equipment. This structural design helps extend the service life of the deoxygenation device and reduce maintenance frequency.

[0057] Specifically, if Figure 4 As shown, a plurality of guide plates 350 are provided in the heating chamber 300, and the plurality of guide plates 350 are arranged in sequence along a zigzag trajectory to form a first guide channel 340 between the support plate 320 and the baffle 330. This arrangement avoids mixing of the second heating medium in the steam inlet channel 321 and the steam outlet channel 322, which is conducive to setting the steam inlet channel 321 and the steam outlet channel 322 on the support plate 320 at the same time.

[0058] In the present application, the deoxygenation device further includes: a steam inlet chamber 500, with the second port 202 communicating with the steam inlet chamber 500; and a first steam inlet pipe 510 disposed within the steam inlet chamber 500. The first steam inlet pipe 510 is provided with a plurality of steam outlet holes 511 spaced apart along the extension direction of the first steam inlet pipe 510, each steam outlet hole 511 communicating with the steam inlet chamber 500. By providing the plurality of spaced apart steam outlet holes 511 on the first steam inlet pipe 510, the first heating steam can be evenly distributed around the heating section 220 of the flow mixing component 200. This helps uniformly heat the liquid within the heating section, avoids localized overheating or uneven heating, and improves heating efficiency and deoxygenation effectiveness. The spaced apart arrangement of the steam outlet holes 511 ensures that the first heating steam can enter the flow mixing component from multiple points, increasing the contact area and points between the steam and the liquid, thereby improving heat exchange efficiency, accelerating the escape of oxygen from the liquid, and thereby increasing the deoxygenation rate. Uniformly introducing the first heated steam through the multiple steam outlets of the first steam inlet pipe 510 effectively reduces the noise and vibration generated by the high-speed steam injection, thereby improving the operational stability of the equipment. The design of the steam inlet chamber 500 and the first steam inlet pipe 510 clarifies the steam inlet path, reduces piping complexity, simplifies the system structure, facilitates routine maintenance and inspection, and reduces maintenance costs.

[0059] During specific implementation, the deoxygenation device further includes a diverter component 600 disposed below the flow mixing component 200. The diverter component 600 is disposed opposite and spaced from the second port 202. The diverter component 600 is provided with a plurality of fourth through holes 610. The deoxygenated liquid flowing out of the second port 202 flows into the steam generating chamber 110 through the fourth through holes 610. The plurality of fourth through holes 610 on the diverter component 600 can evenly distribute the deoxygenated liquid flowing out of the second port 202 of the flow mixing component 200 into the steam generating chamber 110, thereby avoiding local overheating or overcooling, ensuring uniformity and stability of the liquid temperature within the steam generator, and improving evaporation efficiency and steam quality. The diversion component 600 is opposite to the second port 202 and is spaced apart, which can prevent the high-speed deoxygenated liquid from directly impacting the bottom of the steam generating chamber 110 or other components, reducing the mechanical wear and noise caused by the impact of gas and liquid. By evenly dispersing the deoxygenated liquid, local accumulation of liquid in the steam generator can be avoided, reducing the occurrence of "water hammer" phenomenon, improving the operating stability of the steam generator, and reducing the failure rate.

[0060] Preferably, the diverter component 600 includes a first diverter plate 620, a second diverter plate 630 and a third diverter plate 640 arranged in sequence along the vertical direction, and a plurality of fourth through holes 610 are respectively provided on the first diverter plate 620, the second diverter plate 630 and the third diverter plate 640, wherein the aperture of the fourth through hole 610 on the first diverter plate 620 is D1, the aperture of the fourth through hole 610 on the second diverter plate 630 is D2, and the aperture of the third diverter plate 640 is D3, D1>D2>D3, and the fourth through holes on the first diverter plate 620 are staggered with the fourth through holes on the second diverter plate 630, and the fourth through holes on the second diverter plate 630 are staggered with the fourth through holes on the third diverter plate 640. As the aperture gradually decreases from the first manifold plate 620 to the third manifold plate 640, the deoxygenated liquid flowing from the second port 202 of the flow mixing component 200 is evenly and gradually more densely distributed within the steam generation chamber 110, avoiding localized concentration of liquid and improving the uniformity of liquid distribution within the shell heat exchange space. The gradual distribution of apertures from large to small, as well as the staggered arrangement of the fourth through-holes 610, increases the turbulent effect of the liquid flow, improves the heat exchange efficiency between the liquid and the medium within the shell heat exchange space, and accelerates steam generation.

[0061] In a specific implementation, the deoxygenation device also includes: an exhaust channel 710, which is arranged above the mixing component 200 and connected to the first port 201; a filter component 720, which is arranged above the mixing component 200 and located between the exhaust channel 710 and the first port 201, and filters the liquid in the gas-liquid mixture flowing out of the first port 201 through the filter component 720. The filter component 720 is located above the mixing component 200 and between the first port 201 and the exhaust channel 710. Such a design can effectively intercept and filter the liquid in the gas-liquid mixture discharged from the mixing component 200, ensuring that only the gas component can be discharged smoothly through the exhaust channel 710, thereby improving the purity of the gas and the gas-liquid separation efficiency. The liquid separated by the filter component 720 can be recycled, avoiding the waste of residual heat and working fluid in the liquid, improving energy utilization efficiency, and reducing operating costs. The presence of exhaust channel 710 optimizes the gas discharge path, ensuring that the gas is not obstructed by liquid during the discharge process. This avoids discharge obstruction or pressure fluctuations caused by the presence of liquid, ensuring stable system operation. The improved purity of the filtered gas reduces the transient pressure fluctuations caused by the evaporation of droplets in the gas-liquid mixture at high temperatures, reducing the risk of water hammer in the system and improving operational safety.

[0062] In this embodiment, the liquid inlet portion 210 includes a plurality of liquid inlet holes 211, which are arranged at intervals along a first spiral trajectory. The flow mixing component 200 includes: a mixing pipe 240, each of which has a liquid inlet hole 211 disposed therein; a flow guide body 250 disposed within the mixing pipe 240, the flow guide body 250 extending along a second spiral trajectory along the axis of the mixing pipe 240, and a second flow guide channel 260 disposed between the flow guide body 250 and the inner wall surface of the mixing pipe 240. The first and second spiral trajectories have the same spiral direction. Since the liquid inlet holes 211 are arranged along the first spiral trajectory, the liquid to be deoxygenated flows along the spiral trajectory when injected into the mixing pipe 240. This increases the contact area and contact time between the liquid and the heated steam, improves the efficiency of vapor-liquid mixing, and thus enhances the deoxygenation effect. The spiral path design helps the liquid flow smoothly into the mixing pipe 240. Compared to a straight path, the spiral path better disperses the impact of the liquid entering, reduces fluid resistance, and allows the liquid to mix more smoothly with the heated steam. The spiral path design of the flow guide body 250 creates a spiral flow of the heated steam in the second flow guide channel 260. This flow pattern distributes the heated steam more evenly, optimizes the heat exchange process, ensures sufficient heating of the liquid to be deoxygenated, and thus improves deoxygenation efficiency.

[0063] like Figure 16As shown, the present application also provides a steam generator, including a shell 120 and a deoxygenation device 900. A steam generating chamber 110 is provided in the shell 120. The deoxygenation device 900 is provided in the steam generating chamber 110. The deoxygenation device 900 is the deoxygenation device 900 of the above embodiment.

[0064] The deoxygenation device 900 is the deoxygenation device 900 of the above-mentioned embodiment, and the support plate 320 includes a first steam inlet area 323, a steam outlet area 324, a second steam inlet area 325 and a liquid outlet area 326. The liquid outlet area 326 is arranged below the second steam inlet area 325, the steam inlet channel 321 is arranged in the first steam inlet area 323, and the steam outlet channel 322 is arranged in the steam outlet area 324; the second steam inlet area 325 of the support plate 320 is provided with a plurality of fifth through holes 3250, each of which is connected to the steam generating chamber 110, and the second heated steam flowing out of the steam outlet channel 322 flows into the steam generating chamber 110 through the fifth through holes 3250; the liquid outlet area 326 of the support plate 320 is provided with a plurality of sixth through holes 3260, each of which is connected to the steam generating chamber 110.

[0065] The fifth through hole 3250 provided on the support plate 320 can evenly distribute the second heated vapor flowing out of the first steam outlet channel 322 throughout the steam generating chamber 110. The sixth through hole 3260 of the liquid outlet area 326 is designed to ensure that the liquid flowing out of the mixing component 200 can smoothly pass through the liquid outlet area back to the steam generating chamber 110, reducing the risk of liquid loss during the deoxygenation process. Through the structural design of the support plate 320, the second heated vapor can be discharged through the first steam outlet channel 322 of the steam outlet area 324 after heating the deoxygenated liquid, while the liquid is recovered to the steam generating chamber 110 through the sixth through hole 3260 of the liquid outlet area 326. This separation design reduces the waste of heat energy and improves the energy efficiency of the thermal deoxygenation device. The integrated design of the support plate 320 integrates the functions of vapor distribution, liquid recovery, and thermal energy management, simplifies the internal structure of the steam generator, and reduces the number of components.

[0066] The steam generator also includes: an end plate 130, which is buckled on one end of the shell 120, and the end plate 130 is arranged opposite to the support plate 320 of the deaerator 900 to form an end chamber 140 between the end plate 130 and the support plate 320; a fourth partition plate 150, which is respectively connected to the end plate 130 and the support plate 320, and the fourth partition plate 150 is located between the first steam inlet area 323 and the steam outlet area 324; a fifth partition plate 160, which is respectively connected to the end plate 130 and the support plate 320, and the fifth partition plate 160 is located between the first steam inlet area 323 and the second steam inlet area 325; a sixth partition plate 170, which is respectively connected to the end plate 130 and the support plate 320, and the sixth partition plate 170 is located between the second steam inlet area 325 and the liquid outlet area 326. The fourth, fifth, and sixth baffles effectively control and guide the flow of steam. By controlling the flow paths of steam and liquid, the efficiency of heat transfer is improved, heat loss is reduced, and even distribution of steam through the deaerator 900 is ensured, avoiding localized overheating or airflow short-circuits, thereby improving the uniformity and efficiency of steam deoxygenation. The space between the end chamber 140 and the support plate 320, combined with the structure of the deaerator, optimizes the distribution of the deoxygenated liquid, ensuring uniform liquid entry into the steam generator's heating area, thereby improving both the efficiency of liquid heating and the efficiency of steam generation.

[0067] The steam generator also includes a heat exchange tube bundle 111, a drain pipe 112, a liquid baffle 113, a safety valve port 114, an air outlet pipe 115 and a gas-liquid filter 116. The heat exchange tube bundle 111 is arranged at the bottom of the steam generating chamber 110, the drain pipe 112 is connected to the steam generating chamber 110, the liquid baffle 113 is arranged below the air outlet pipe 115 and the safety valve port 114, and the gas-liquid filter 116 is arranged above the heat exchange tube bundle 111.

[0068] like Figure 16 As shown, a thermal deoxidizer 900 is designed inside the steam generator shell 120, above the heat exchange tube bundle 111 and near one end of the water chamber of the tube-side air inlet pipe. Figure 2 As shown, the deionized water enters the liquid inlet chamber 400 from the liquid inlet pipe 430 on the side of the shell 120. The liquid inlet chamber 400 is composed of a first partition plate 410, a second partition plate 420, the shell 120, a support plate 320 and a baffle 330. Figure 14 As shown, the liquid inlet pipe 430 extends into the liquid inlet chamber 400 and a liquid outlet hole 431 is machined. The first through hole 411 and the second through hole 421 are machined on the first partition 410 and the second partition 420 respectively. The flow mixing component 200 is vertically placed in the first through hole 411 and the second through hole 421. The flow guide body 250 is set inside the flow mixing component 200. Figure 3 and Figure 10As shown, the wall of the flow mixing component 200 extending into the liquid inlet chamber 400 is machined with spirally distributed liquid inlet holes 211. The bottom of the flow mixing component 200 is welded to the third partition plate 310 with the third through hole 311. The second partition plate 420, the third partition plate 310, the housing 120, the support plate 320, and the baffle 330 form the heating chamber 300.

[0069] like Figure 2 As shown, the heating steam (the first heating steam in the above embodiment) enters the steam inlet chamber 500 from the first steam inlet pipe 510 on the side of the shell. The steam inlet chamber 500 is composed of the third partition plate 310, the first diverter plate 620, the shell 120, the support plate 320 and the baffle 330. Figure 15 As shown, the first steam inlet pipe 510 extends into the steam inlet chamber 500 and a steam hole 511 is processed. The bottom of the first diverter plate 620 is the second diverter plate 630 and the third diverter plate 640. Figure 3 As shown, the fourth through holes 610 are processed on all three layers of the manifold and are staggered. Figure 2 As shown, a filter component 720 is disposed above the flow mixing component 200 and the first partition plate 410 , and an exhaust channel 710 is disposed above the filter component 720 .

[0070] like Figure 1 As shown, desalted water enters the liquid inlet chamber 400 through the outlet hole 431 on the liquid inlet pipe 430. Within the liquid inlet chamber 400, it enters the spiral flow channel (i.e., the aforementioned second flow guide channel 260) through the inlet hole 211 on the flow mixing component 200, flowing in a spiral from top to bottom. Heating steam enters the steam inlet chamber 500 through the outlet hole 511 on the first steam inlet pipe 510. Within the steam inlet chamber 500, it enters the spiral flow channel from the bottom of the flow mixing component 200, flowing in a spiral from bottom to top. Under a certain pressure differential, desalted water is ejected from the inlet hole 211 into the spiral flow channel, forming a jet. The spiral flow channel is filled with rising heating steam. The desalted water draws in a large amount of heating steam during the spiral motion of the jet, generating a strong mixing and heating effect in a very short time and within a very short travel distance, significantly raising the water temperature. Simultaneously, the desalted water continues to spiral downward along the walls of the spiral flow channel, forming a thinning and expanding water film. This increases the contact area with the rising heating steam, facilitating mass and heat transfer. The heated steam rapidly heats the desalted water to saturation temperature. Escaping oxygen cannot diffuse freely within the spiral flow channel and must be discharged from the top of the mixing component 200 along with the rising steam. The rising steam, carrying oxygen, passes through the filter component 720 to filter out liquid droplets before being discharged from the exhaust channel 710. After thermal deoxygenation, the desalted water passes sequentially through the staggered fourth through-holes 610 on the first diverter plate 620, the second diverter plate 630, and the third diverter plate 640. After equalization, it enters the shell-side heat exchange space of the steam generator to replenish the steam generator.

[0071] like Figure 4 and Figure 5 As shown, vertical guide plates 350 are positioned within the heating chamber 300 to form a baffle channel (i.e., the aforementioned first guide channel 340). A steam inlet channel 321 and a steam outlet channel 322 are formed on the support plate 320. High-temperature steam from the tube side enters the heating chamber 300 through the second steam inlet pipe 180 on the water chamber via the steam inlet channel 321. During this baffled motion, the high-temperature steam flows through the flow mixing component 200, further heating the desalted water within the spiral flow channel and accelerating oxygen release. Water chamber baffles (including fourth, fifth, and sixth baffles) are positioned within the water chamber. High-temperature steam from the tube side enters the water chamber through the steam outlet channel 322 and then enters the heat exchange tube bundle 111, heating the desalted water in the steam generator shell to produce steam. The high-temperature steam from the tube side condenses and exchanges heat within the heat exchange tube bundle 111 before being discharged through the liquid outlet pipe 190.

[0072] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0073] According to the deoxygenation device of the present application, it is arranged in the steam generating chamber 110 of the target workpiece 100, wherein the deoxygenation device includes a flow mixing component 200, which is arranged in the steam generating chamber 110, and the flow mixing component 200 includes a first port 201 and a second port 202 arranged opposite to each other in a vertical direction, the first port 201 is used to discharge gas, and the second port 202 is used to pass the first heating vapor, and the second port 202 is connected to the steam generating chamber 110; the flow mixing component 200 is also provided with a liquid inlet 210, the liquid inlet 210 is located at one end of the flow mixing component 200 close to the first port 201, and the liquid inlet 210 is used to pass the liquid to be deoxygenated into the flow mixing component 200, so that the first heating vapor is mixed with the liquid to be deoxygenated and heats the liquid to be deoxygenated during the process of flowing upward in the flow mixing component 200, thereby deoxygenating the liquid to be deoxygenated. With this arrangement, the liquid to be deoxygenated flows downward along the flow mixing component 200 under the action of its own gravity, and the first heating gas, due to its lighter weight, flows from bottom to top along the flow mixing component 200, and then the first heating gas and the liquid to be deoxygenated are mixed in the flow mixing component 200. At the same time, the first heating gas heats the liquid to be deoxygenated, so that the oxygen in the liquid to be deoxygenated is precipitated, and the deoxygenated liquid directly falls into the steam generating chamber 110 through the second port 202, and the oxygen is directly discharged through the first port 201. There is no need to set a separate deoxygenation pipeline outside the target workpiece 100, so that the deoxygenated liquid directly participates in the steam generation reaction in the steam generating chamber 110, the overall structure is simpler, and installation space is saved.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
