Description

An ultrapure water separation device and method for use in solar thermal power plants Technical Field

[0001] This invention relates to the field of ultrapure water processing technology, specifically to an ultrapure water separation device and method used in solar thermal power plants. Background Technology

[0002] The preparation process of ultrapure water is very strict, requiring multi-stage filtration and treatment methods such as pretreatment, reverse osmosis technology, ultrapurification treatment, and post-treatment to ensure its extremely high purity. At the same time, the conductivity of ultrapure water used in solar thermal power plants needs to be controlled, requiring the conductivity of ultrapure water to be very low to ensure its high purity.

[0003] In concentrated solar power (CSP) plants, ultrapure water may be used in various critical processes such as cooling, cleaning, and heat transfer. The purity requirements for water are extremely high. Only water with high purity and low impurities and ions can ensure the normal operation of CSP plant equipment and the stability of products, and extend the service life of equipment. Therefore, it is necessary to control the conductivity of raw water during ultrapure water separation. At the same time, the CO2 content of raw water needs to be controlled to avoid adverse effects on conductivity.

[0004] Referring to the ultrapure water pretreatment system disclosed in patent application CN204529495U, the ultrapure water system uses a pressurized pump to sequentially deliver water to a PP filter and an activated carbon filter for filtration, so that the water can gradually become clear from a turbid state. This system more effectively solves the problem that suspended particles and coarse impurities in tap water can easily clog the subsequent fine treatment unit.

[0005] Currently, ultrapure water separation equipment mainly consists of a pretreatment system, a reverse osmosis system, and a post-treatment system. However, the pretreatment of ultrapure water separation equipment often uses interception materials. For example, the ultrapure water system mentioned above also uses PP filters and activated carbon filters for filtration. However, the pretreatment of ultrapure water separation equipment cannot control the gas content in the raw water, which easily affects the conductivity of ultrapure water and its subsequent use in solar thermal power plants. At the same time, the pretreatment of ultrapure water separation equipment cannot quickly precipitate impurities in the raw water, which increases the processing pressure of the subsequent reverse osmosis system and post-treatment system, increases the maintenance frequency, and easily leads to clogging and decreased filtration efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrapure water separation device and method for use in solar thermal power plants, so as to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to an ultrapure water separation device for use in solar thermal power plants, comprising an ultrapure water unit and further comprising:

[0009] The raw water tank is located on one side of the ultrapure water equipment, and a tank cover is detachably and sealed on the top of the raw water tank.

[0010] A conical material chamber is set inside the raw water tank. A sealing ring for sealing is set on the conical material chamber. A discharge mechanism is set on the conical material chamber. An isolation ring is set above the conical material chamber inside the raw water tank. An exhaust channel is opened through one side of the isolation ring. The isolation ring and the conical material chamber form a replacement space and a processing space inside the raw water tank. A venting mechanism is set on the isolation ring in the processing space.

[0011] The control mechanism, located on the tank lid, controls the discharge of the treated raw water. This control mechanism can also control the position change of the venting mechanism, and at the same time, it can control the sealing ring to complete the power connection with the discharge mechanism.

[0012] The replacement mechanism, located on the sealing ring, controls the gas content of the raw water within the replacement space. The replacement mechanism consists of a central platform and multiple actuating units. The central platform is located at the center of the sealing ring, and the multiple actuating units are arranged in a circular array around the central platform to control the gas.

[0013] Furthermore, it also includes:

[0014] An annular cavity is set on a conical material cavity. Multiple injection nozzles are arranged in a circular array at the bottom of the annular cavity, and a friction pad is set on the upper surface of the annular cavity.

[0015] Multiple extrusion stages are arranged in a circular array on the inner wall of the annular cavity.

[0016] Furthermore, the ventilation mechanism includes:

[0019] An arc-shaped push groove is formed on the inner wall of the hollow sleeve;

[0020] A rectangular frame is set on the lower surface of the can lid, corresponding to the exhaust channel. A rectangular sliding area is opened inside the rectangular frame. A gas delivery pipe is connected and installed at the top of the rectangular frame, and a detector is installed at the top inside the rectangular frame.

[0021] A rectangular pressure plate is slidably set in a rectangular sliding area to complete the auxiliary pressing of the breathable membrane. Multiple return springs are set in the rectangular sliding area. The return springs pull the rectangular pressure plate to move upward in the rectangular sliding area. Two protrusions are symmetrically set at the bottom of the rectangular pressure plate.

[0022] The control arm, mounted on the control mechanism, performs active control of the rectangular pressure plate.

[0023] Furthermore, the control mechanism includes:

[0024] An electric actuator is mounted on the can lid;

[0025] The control shaft is located at the output end of the electric actuator and slides through the hollow sleeve. The bottom of the control shaft is rotatably connected to the center platform, and the control shaft is fixedly connected to the control arm. The position control of the control arm is achieved through the control shaft.

[0026] The trigger protrusion is fixedly set on one side of the control shaft, and the trigger protrusion is slidably engaged in the arc-shaped push groove. The switching of the breathable membrane is completed by the cooperation between the trigger protrusion and the arc-shaped push groove.

[0027] Furthermore, each toggle unit includes:

[0028] Two parallel arms are symmetrically spaced on the sealing ring.

[0029] A rotating shaft is rotatably positioned between two parallel arms. An injection pipe is threaded through the rotating shaft, and multiple conveyor platforms are arranged side by side and interconnected on the injection pipe. Each conveyor platform has a nozzle installed at its top and bottom.

[0030] A friction wheel is positioned at the front end of the rotating shaft and makes frictional contact with the upper surface of the annular cavity.

[0031] An annular material chamber is set on a central platform. An annular end cap is rotatably installed on the upper surface of the annular material chamber. Multiple interconnecting pipes are connected around the annular material chamber. Each interconnecting pipe is rotatably connected to the injection pipe to complete the gas delivery.

[0032] A rotary motor is mounted on the control mechanism, and the output end of the rotary motor is connected to the central platform for transmission.

[0033] Furthermore, each toggle unit also includes:

[0034] A push shaft is slidably mounted on one of the parallel arms. An mounting arm is installed at the tail of the push shaft, and a ball bearing is installed at the front end of the push shaft.

[0035] A control spring is sleeved outside the push shaft, and the control spring is located between the parallel arm and the mounting arm;

[0036] Multiple interference rings are arranged side by side at intervals on the mounting arm. Under normal conditions, each interference ring is located on one side of the nozzle.

[0037] Furthermore, each interference ring includes:

[0038] A ring-shaped component is mounted on the mounting arm, and multiple open areas are arranged in a circular array on the ring-shaped component;

[0039] Multiple toggle plates are rotated and positioned within multiple open areas.

[0040] Furthermore, the discharge mechanism includes:

[0041] A circular filter cylinder is connected to the bottom of a conical material chamber. Multiple filter holes are arranged in a circular array around the circular filter cylinder. A discharge pipe is connected to the bottom of the circular filter cylinder.

[0042] The discharge auger is rotatably mounted inside the discharge pipe via a bracket, and multiple scrapers are installed inside the circular filter cylinder. These scrapers are connected to the top of the discharge auger via a transmission mechanism.

[0043] The connecting component is positioned between the sealing ring and the circular filter cartridge to complete the power connection.

[0044] Furthermore, the connector includes:

[0045] The mounting frame is set on the top of the discharge auger, and the first friction ring is mounted on the mounting frame via a bracket;

[0046] A sliding rod is set on the lower surface of the sealing ring and slides through the first friction ring. A second friction ring is installed at the bottom of the sliding rod. The power connection control is completed through the frictional contact between the second friction ring and the first friction ring.

[0047] This invention also provides a method for separating ultrapure water for use in solar thermal power plants, which specifically includes the following steps:

[0048] Step 1: The sealing ring is moved down by the control mechanism to seal the annular cavity, and the raw water is sent into the replacement space to wait for processing;

[0049] Step 2: Inert gas is introduced into the replacement space and released synchronously at multiple points through multiple actuation units, so that the inert gas enters the raw water to complete the replacement.

[0050] Step 3: By incorporating a ventilated mechanism, the gas discharged during the replacement process can be released.

[0051] Step 4: The impurities generated during the processing are discharged through the set discharge mechanism.

[0052] Compared with the prior art, the beneficial effects of the present invention are:

[0053] This invention features a replacement mechanism that uses multiple actuating units to release gas synchronously at multiple points, allowing inert gas to enter the raw water and replace it. This effectively reduces the carbon dioxide content in the raw water and facilitates control over its conductivity. Simultaneously, the sealing ring and multiple actuating units can rotate, actuating the raw water within the replacement space to ensure thorough mixing of the treatment agent with the raw water. This allows for control over carbon dioxide and impurities in the raw water, enabling multi-mode treatment of the raw water, reducing the workload of subsequent raw water treatment, and improving treatment accuracy and efficiency.

[0054] This invention incorporates a control mechanism that synchronously controls the venting and discharging mechanisms during operation, achieving dynamic connection between them. This allows the venting mechanism to switch once during a single treatment process, maintaining a good separation state. Meanwhile, the design of the discharging mechanism enables rapid separation and discharge of flocculated impurities in the raw water, and the discharging mechanism can dynamically separate from the sealing ring, effectively reducing the load and extending the service life.

[0055] This invention incorporates a venting mechanism. Under normal conditions, the control arm presses the rectangular pressure plate tightly against the venting membrane, ensuring gas flow. The design of the rectangular frame and the rectangular pressure plate isolates the interior of the rectangular frame from the processing space, enabling proactive cleaning of the venting membrane and preventing residual raw water from affecting the performance. Furthermore, the venting mechanism can be freely switched and controlled, maintaining optimal operation and preventing any impact on the treatment accuracy of the raw water.

[0056] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0072] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0073] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0074] Example 1: This invention provides a technical solution: As shown in Figures 1, 2, and 3, an ultrapure water separation device for use in a solar thermal power plant includes an ultrapure water device 1. The ultrapure water device 1 consists of a pretreatment system, a reverse osmosis system, and a post-treatment system, capable of fully treating pure water. It also includes:

[0075] Raw water tank 2 is installed on one side of ultrapure water equipment 1. Raw water tank 2 is connected to ultrapure water equipment 1 through a pipeline to complete the transportation. A water inlet pipe 3 is installed on the top side of raw water tank 2, and a water outlet pipe 4 is installed on the bottom side of raw water tank 2. A gas cylinder is installed on the side of raw water tank 2. The gas cylinder is filled with inert gas and is connected to a gas filling pipe through a pipeline. A tank cover 5 is detachably and sealed on the top of raw water tank 2.

[0076] As shown in Figures 4 and 5, a conical material cavity 6 is set inside the raw water tank 2. A sealing ring 7 for sealing is set on the conical material cavity 6. A discharge mechanism is set on the conical material cavity 6. An isolation ring 8 is set above the conical material cavity 6 inside the raw water tank 2. An exhaust channel 9 is opened through one side of the isolation ring 8. The isolation ring 8 and the conical material cavity 6 form a displacement space 10 and a processing space 11 inside the raw water tank 2. A venting mechanism is set on the isolation ring 8 in the processing space 11. The displacement space 10 is interconnected with the water inlet pipe 3. A drying inlet pipe 12 and a drying outlet pipe 13 are interconnected between the tank cover 5 and the processing space 11, respectively.

[0077] The control mechanism, located on the tank cover 5, controls the discharge of the treated raw water. This control mechanism can simultaneously control the position change of the venting mechanism, and at the same time, it can control the sealing ring 7 to complete the power connection with the discharge mechanism.

[0078] The replacement mechanism is set on the sealing ring 7 to control the gas content of the raw water in the replacement space 10. The replacement mechanism consists of a central platform 14 and multiple actuating units. The central platform 14 is set at the center of the sealing ring 7, and the multiple actuating units are arranged in a circular array around the central platform 14 to complete the gas control.

[0079] In this embodiment of the invention, it further includes:

[0080] An annular cavity 15 is set on the conical material cavity 6. The annular cavity 15 is connected to the external treatment agent through a pipe. Multiple injection nozzles are arranged in a circular array at the bottom of the annular cavity 15, and a friction pad is set on the upper surface of the annular cavity 15.

[0081] Multiple extrusion stages 16 are arranged in a circular array on the inner wall of the annular cavity 15. Each extrusion stage 16 has a trapezoidal structure and inclined surfaces on both sides.

[0082] Among them, the rotary motor 36, the electric push rod 26 and the detector are all connected to switches via wires, and the switches are electrically connected to controllers. The specific structure of the controllers is not limited.

[0083] Example 2: Based on the replacement mechanism provided in Example 1, this example provides a further technical solution for the replacement mechanism.

[0084] As shown in Figures 10 and 12, each actuating unit includes:

[0085] Two parallel arms 29 are symmetrically spaced on the sealing ring 7;

[0086] A rotating shaft 30 is rotatably positioned between two parallel arms 29. An injection pipe 31 is threaded through the rotating shaft 30. Multiple conveyor platforms 32 are arranged side by side and interconnected on the injection pipe 31. Each conveyor platform 32 has a nozzle installed at its top and bottom.

[0087] Friction wheel 33 is disposed at the front end of rotating shaft 30 and in frictional contact with the upper surface of annular cavity 15;

[0088] An annular material chamber 34 is set on the central platform 14. An annular end cover is rotatably installed on the upper surface of the annular material chamber 34. The annular end cover can be connected to the control shaft 27 through the bracket. A gas filling pipe is connected to the annular end cover. Multiple interconnecting pipes 35 are connected around the annular material chamber 34. Each interconnecting pipe 35 is rotatably connected to the filling pipe 31 to complete the gas delivery.

[0089] A rotary motor 36 is mounted on the control shaft 27 of the control mechanism, and the output end of the rotary motor 36 is connected to the central platform 14 for transmission. Specifically, an installation area for cooperating with the rotary motor 36 is provided on the control shaft 27.

[0090] It is worth noting that when treating raw water in multiple ways: An external inert gas is introduced into the annular material chamber 34 via a gas filling pipe through a replacement mechanism. Then, the inert gas is fed into the conveying platform 32 via a filling pipe 31. It is then sprayed synchronously from top to bottom through nozzles in the replacement space 10, creating a multi-point synchronous replacement effect within the space and accelerating the gas replacement efficiency. Subsequently, a rotary motor 36 is controlled to cause the sealing ring 7 and its multiple actuating units to rotate synchronously, dynamically adjusting the gas release position and simultaneously agitating the raw water within the replacement space 10. At the same time, the treatment agent is sprayed out through multiple filling nozzles, making... The treatment agent can fully contact and mix with the raw water, accelerate the flocculation of impurities in the raw water, and complete the multi-mode treatment of the raw water, which is beneficial to the subsequent preparation of ultrapure water and ensures quality. At the same time, the design of the annular cavity 15 is adopted. When multiple toggle units rotate in a circle, the friction wheel 33 rubs against the annular cavity 15. Therefore, during the rotation, the rotating shaft 30 and the nozzle generate a self-rotation effect in the state of revolution, which allows inert gas to be released into the raw water from multiple directions, further improving the replacement efficiency and replacement effect. The toggle unit design can also fully mix the raw water and the treatment agent, which is conducive to the efficient treatment of raw water.

[0091] As shown in Figures 13 and 14, each actuating unit also includes:

[0092] A push shaft 37 is slidably mounted on one of the parallel arms 29. An mounting arm 38 is installed at the tail of the push shaft 37. A sliding track that cooperates with the mounting arm 38 is provided on the sealing ring 7. A ball bearing is installed at the front end of the push shaft 37.

[0093] A control spring 39 is sleeved on the outside of the push shaft 37 and is located between the parallel arm 29 and the mounting arm 38. The control spring 39 drives the push shaft 37 to move toward the annular cavity 15.

[0094] Multiple interference rings 40 are arranged side by side at intervals on the mounting arm 38. The number of multiple interference rings 40 is the same as the number of multiple conveyor tables 32. Under normal conditions, each interference ring 40 is located on one side of the nozzle.

[0095] Each interference ring 40 includes:

[0096] The annular member 401 is disposed on the mounting arm 38, and multiple open areas are arranged in a circular array on the annular member 401;

[0097] Multiple toggle plates 402 are rotatably positioned within multiple open areas;

[0098] It is worth noting that: when multiple actuating units rotate simultaneously, the push shaft 37 slides against the inner wall of the annular cavity 15. During rotation, the balls on the push shaft 37 contact the extrusion table 16 and are guided by the inclined surface of the extrusion table 16 to complete the movement, causing the push shaft 37 to move against the control spring 39. This causes the mounting arm 38 and its multiple interference rings 40 to move accordingly, allowing the interference rings 40 to move to the nozzle area to complete the interference. This can interfere with and agitate the inert gas, allowing the gas to be fully released and preventing it from accumulating at the nozzle, further improving the contact efficiency between the gas and the raw water. At the same time, multiple actuating plates 402 are provided on the interference rings 40. When the interference rings 40 move to the nozzle, the actuating plates 402 rotate due to the gas impact, which can guide the gas to diffuse to different positions, further improving the gas replacement efficiency.

[0099] As shown in Figures 6 and 7, in this embodiment of the invention, the breathable mechanism includes:

[0100] Hollow sleeve 17 is rotatably positioned at the center of isolation ring 8;

[0101] The breathable membrane 18 is rotatably mounted on the upper surface of the isolation ring 8. The breathable membrane 18 consists of a fixed frame and a water-proof breathable membrane, and a one-way bearing 19 is provided between the breathable membrane 18 and the hollow sleeve 17.

[0102] The arc-shaped push groove 20 is opened on the inner wall of the hollow sleeve 17. The arc-shaped push groove 20 has an overall arc design, which can control the rotation of the breathable membrane 18.

[0103] A rectangular frame 21 is set on the lower surface of the can lid 5, corresponding to the exhaust channel 9. A rectangular sliding area 22 is opened in the rectangular frame 21. A gas delivery pipe is connected to the top of the rectangular frame 21. A detector 23 is installed in the top of the rectangular frame 21. The detector 23 is a gas detector that can detect the type of exhaust gas.

[0104] A rectangular pressure plate 24 is slidably disposed within a rectangular sliding area 22 to assist in pressing the breathable membrane 18. Multiple return springs are provided within the rectangular sliding area 22. The return springs pull the rectangular pressure plate 24 upward within the rectangular sliding area 22. Two protrusions are symmetrically provided at the bottom of the rectangular pressure plate 24.

[0105] The control arm 25 is mounted on the control mechanism to perform active control of the rectangular pressure plate 24. Under normal conditions, the control arm 25 contacts the protrusion to press the rectangular pressure plate 24 tightly.

[0106] It is worth noting that when the gas is discharged: through the ventilation mechanism, the gas released during gas replacement is discharged through the exhaust channel 9, and is released through the ventilation membrane 18 and sent into the space formed by the rectangular frame 21, thus completing the isolation of the raw water. At the same time, the gas entering the rectangular frame 21 is detected by the detector 23, which can monitor the gas status in real time. Then the gas is discharged through the gas delivery pipe. When the detector 23 detects that it is qualified, the delivery of inert gas is stopped. Meanwhile, a rectangular pressure plate 24 is set on the rectangular frame 21. Under normal conditions, the control arm 25 presses the rectangular pressure plate 24 tightly, so that the rectangular pressure plate 24 is in close contact with the ventilation membrane 18, ensuring the flow of gas. Due to the design of the rectangular frame 21 and the rectangular pressure plate 24, the rectangular frame 21 is isolated from the processing space 11. Therefore, the inert drying gas is introduced and drawn out through the drying inlet pipe 12 and the drying outlet pipe 13, which can actively clean the ventilation membrane 18 and avoid the large amount of raw water remaining on the ventilation membrane 18 from affecting the use effect.

[0107] Example 3: Based on the control mechanism provided in Example 1, this example provides a further technical solution for the control mechanism.

[0108] As shown in Figures 8 and 9, the control mechanism includes:

[0109] Electric actuator 26 is mounted on can lid 5;

[0110] The control shaft 27 is located at the output end of the electric actuator 26 and slides through the hollow sleeve 17. The bottom of the control shaft 27 is rotatably connected to the center platform 14. The control shaft 27 is fixedly connected to the control arm 25. The position control of the control arm 25 is achieved through the control shaft 27.

[0111] The trigger protrusion 28 is fixedly set on one side of the control shaft 27, and the trigger protrusion 28 is correspondingly slidably engaged in the arc-shaped push groove 20. The switching of the breathable membrane 18 is completed by the cooperation between the trigger protrusion 28 and the arc-shaped push groove 20.

[0112] It is worth noting that when controlling the discharge of the treated raw water: A control mechanism is provided. After a single treatment is completed, the electric actuator 26 is activated, pulling the control shaft 27 and sealing ring 7 upwards, opening the conical material chamber 6. The raw water is released into the circular filter cartridge 41 for interception, and then the clean raw water enters the lower part of the raw water tank 2 for storage. During the upward movement of the control shaft 27, the control arm 25 moves upwards and separates from the protrusion. The rectangular pressure plate 24, under the influence of the reset spring, moves upwards and separates from the permeable membrane 18, facilitating the subsequent rotation of the permeable membrane 18. This then drives the trigger protrusion 28 to move upwards synchronously. During the upward movement of the trigger protrusion 28, it is restricted by the arc-shaped push groove 20. At this time, the one-way bearing 19 is in a locked state, allowing... The hollow sleeve 17 rotates, synchronously rotating the breathable membrane 18, which transfers the breathable membrane 18 from the clean area to the exhaust channel 9 area for replacement. When the control shaft 27 and the sealing ring 7 move upward, they pull the second friction ring 48 upward to make friction contact with the first friction ring 46, thus completing the power connection and facilitating subsequent material discharge. When the electric push rod 26 drives the control shaft 27 to move downward and reset, the control arm 25 moves downward to reset the rectangular pressure plate 24 and press the breathable membrane 18. However, the one-way bearing 19 rotates without transmitting power, allowing the hollow sleeve 17 to complete its self-rotation reset without interfering with the breathable membrane 18. The first friction ring 46 and the second friction ring 48 separate, thus interrupting the power.

[0113] As shown in Figure 11, in this embodiment of the invention, the discharge mechanism includes:

[0114] A circular filter cylinder 41 is connected to the bottom of the conical material chamber 6. Multiple filter holes are arranged in a circular array around the circular filter cylinder 41. A discharge pipe 42 is connected to the bottom of the circular filter cylinder 41 and is connected to the external waste tank.

[0115] The discharge auger 43 is rotatably mounted inside the discharge pipe 42 via a bracket, and multiple scrapers 44 are provided inside the circular filter cylinder 41. The multiple scrapers 44 are connected to the top of the discharge auger 43 via a transmission.

[0116] A connecting component is installed between the sealing ring 7 and the circular filter cartridge 41 to complete the power connection;

[0117] In this embodiment of the invention, the connector includes:

[0118] Mounting bracket 45 is set on the top of the discharge auger 43, and the first friction ring 46 is mounted on the mounting bracket 45 via a bracket;

[0119] A sliding rod 47 is set on the lower surface of the sealing ring 7, and the sliding rod 47 slides through the first friction ring 46. A second friction ring 48 is installed at the bottom of the sliding rod 47. The power connection control is completed by the frictional contact between the second friction ring 48 and the first friction ring 46.

[0120] It is worth noting that when purifying the treated raw water: A discharge mechanism is provided. After the first friction ring 46 and the second friction ring 48 complete the power connection, the rotary motor 36 is started, causing the sealing ring 7 to rotate. Due to the frictional contact between the first friction ring 46 and the second friction ring 48, the rotational force is transmitted to multiple scrapers 44 and the discharge auger 43. The multiple scrapers 44 scrape and clean the circular filter cylinder 41, preventing blockage during raw water release. Simultaneously, the discharge auger 43 discharges the accumulated impurities inside the circular filter cylinder 41 through the discharge pipe 42, completing the self-cleaning process, preventing impurity accumulation, and reducing cleaning difficulty.

[0121] Example 4: A method for separating ultrapure water used in a solar thermal power plant, the method specifically includes the following steps:

[0122] Step 1: Drive the sealing ring 7 downward through the control mechanism to seal the annular cavity 15, and send the raw water into the replacement space 10 to wait for processing;

[0123] Step 2: Inert gas is introduced into the replacement space 10 and released synchronously at multiple points through multiple actuation units, so that the inert gas enters the raw water to complete the replacement.

[0124] Step 3: By incorporating a ventilated mechanism, the gas discharged during the replacement process can be released.

[0125] Step 4: The impurities generated during the processing are discharged through the set discharge mechanism.

[0126] This invention provides an ultrapure water separation device and method for use in a solar thermal power plant. The specific working principle is as follows: First, a control mechanism drives the sealing ring 7 downwards to seal the annular cavity 15. Then, raw water is sent into the displacement space 10, and simultaneously, inert gas is sent into the annular material cavity 34. Multiple actuating units simultaneously release the gas at multiple points, causing the inert gas to enter the raw water and complete the displacement, effectively reducing the carbon dioxide content in the raw water and facilitating the control of the raw water's conductivity. Simultaneously, the sealing ring 7 and the multiple actuating units can rotate, actuating the raw water within the displacement space 10. At the same time, a treatment agent can be added according to the raw water volume, allowing the treatment agent to fully mix with the raw water, effectively controlling carbon dioxide and impurities in the raw water. The multi-mode treatment of raw water reduces the workload of subsequent raw water treatment, improves treatment accuracy and efficiency. By setting up a venting mechanism, the gas discharged during the replacement process can be extracted and detected. At the same time, the control mechanism can synchronously control the venting mechanism and the discharge mechanism during operation, realizing the dynamic connection between the venting mechanism and the discharge mechanism. This allows the venting mechanism to switch once in a single treatment process, keeping the venting mechanism in a good separation state. Meanwhile, the design of the discharge mechanism can quickly separate and discharge flocculated impurities in the raw water, reducing the workload of subsequent cleaning. Moreover, the discharge mechanism can dynamically separate from the sealing ring 7, effectively reducing the load, making the equipment operation more stable, and extending its service life.
