Description

Technical Field

[0001] The present invention relates to the technical field of ultrapure water processing, and in particular to an ultrapure water separation device and method used in a photothermal power station. Background Art

[0002] The preparation process of ultrapure water is very strict, requiring the use of pre-treatment, reverse osmosis technology, ultrapurification treatment and post-treatment and other multi-stage filtration and treatment methods to ensure its extremely high purity. At the same time, the conductivity of ultrapure water used in solar thermal power stations needs to be controlled, requiring the conductivity of ultrapure water to be very low to ensure its high purity. In a CSP plant, ultrapure water may be used in a variety of key processes such as cooling, cleaning, and heat transfer. The purity of water is very high. Only water with high purity and low impurities and ions can ensure the normal operation of CSP equipment and the stability of products, and extend the service life of equipment. Therefore, it is necessary to control the conductivity of raw water in ultrapure water separation. At the same time, it is necessary to control the raw water CO 2 content to avoid its adverse effect on conductivity.

[0003] An ultrapure water pretreatment system is disclosed in a patent application with reference to publication number CN204529495U. The ultrapure water system uses a pressure pump to sequentially transport water to a PP filter and an activated carbon filter for filtration, so that the water can gradually become clear from a turbid state, thereby more perfectly solving the problem that suspended particles and coarser impurities in tap water enter a subsequent fine treatment unit and easily clog the subsequent fine treatment unit.

[0004] Currently, ultrapure water separation equipment is mostly composed of a pretreatment system, a reverse osmosis system and a post-treatment system. However, the pretreatment of ultrapure water separation equipment is mostly composed of interception materials. For example, the above-mentioned ultrapure water system also uses PP filters and activated carbon filters for filtration. However, the gas content in the raw water cannot be controlled in the pretreatment of ultrapure water separation equipment, which can easily affect the conductivity of ultrapure water and the subsequent use of ultrapure water in solar thermal power stations. 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 the post-treatment system, increases the maintenance frequency, and is prone to blockage and reduced filtering effect.

The displacement mechanism is composed of a central platform 14 and a plurality of toggle units. The central platform 14 is arranged at the center of the sealing ring 7, and the plurality of toggle units are arranged in a circular array around the central platform 14 to complete the gas control. In the embodiment of the present invention, it also includes: The annular cavity 15 is arranged on the conical cavity 6. The annular cavity 15 is connected with the external treatment agent through a pipeline. A plurality of filling nozzles are arranged in a circular array at the bottom of the annular cavity 15, and a friction pad is arranged on the upper surface of the annular cavity 15. A plurality of extrusion platforms 16 are arranged in a circular array on the inner wall of the annular cavity 15 . Each extrusion platform 16 is a trapezoidal structure, and inclined surfaces are arranged on both sides of the extrusion platform 16 .

[0024] Among them, the electrical components such as the rotating motor 36, the electric push rod 26 and the detector are all connected to the switch through the wire, and the switch is electrically connected to the controller, and the specific structure of the controller is not limited.

[0025] Embodiment 2: Based on the replacement mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the replacement mechanism.

[0026] like Fig.10 and Fig.12 As shown, each toggle unit includes: Two parallel arms 29 are symmetrically spaced and arranged on the sealing ring 7; A rotating shaft 30 is rotatably disposed between the two parallel arms 29. A filling pipe 31 is provided on the rotating shaft 30. A plurality of conveying platforms 32 are arranged in parallel and interconnected on the filling pipe 31. A nozzle is connected and installed on the top and bottom of each conveying platform 32. The friction wheel 33 is arranged at the front end of the rotating shaft 30 and is in friction contact with the upper surface of the annular cavity 15; The annular material chamber 34 is arranged on the center platform 14, and an annular end cover is rotatably installed on the upper surface of the annular material chamber 34, and the annular end cover can be connected to the control shaft 27 through a bracket, and a gas filling pipe is connected and installed on the annular end cover, and a plurality of interconnecting pipes 35 are arranged around the annular material chamber 34, and each interconnecting pipe 35 is rotatably connected to the filling pipe 31 to complete gas transportation; The rotating motor 36 is arranged on the control shaft 27 of the control mechanism, and the output end of the rotating motor 36 is transmission-connected with the center platform 14. Specifically, a mounting area for cooperating with the rotating motor 36 is provided on the control shaft 27; It is worth noting that: when the raw water is treated in multiple ways: by setting up a replacement mechanism, the external inert gas is sent into the annular material chamber 34 through the gas filling pipe, and then the inert gas is sent into the conveying platform 32 through the filling pipe 31, and then the nozzle is used to complete the upper and lower synchronous spraying in the replacement space 10, so that the replacement space 10 produces a multi-point synchronous replacement effect, which accelerates the gas replacement efficiency. After that, the rotary motor 36 is controlled to make the sealing ring 7 and the multiple toggle units thereon rotate synchronously, which can complete the dynamic movement adjustment according to the release position of the gas, and at the same time, the raw water in the replacement space 10 can be stirred. At the same time, the treatment agent is sprayed out through multiple filling nozzles, so that The treatment agent can be fully contacted and mixed with the raw water, accelerate the flocculation of impurities in the raw water, complete the multi-mode treatment of the raw water, facilitate the subsequent preparation of ultrapure water, and ensure the quality. At the same time, the design of the annular cavity 15 is adopted. When the multiple toggle units rotate in a circle, the friction wheel 33 is in friction contact with the annular cavity 15. Therefore, during the rotation process, the rotating shaft 30 and the nozzle produce a self-rotation effect in the state of revolution, so that the inert gas can be released into the raw water from multiple directions, further improving the replacement efficiency and replacement effect. The design of the toggle unit can simultaneously complete the full mixing of the raw water and the treatment agent, which is conducive to the efficient treatment of the raw water. like Fig.13 and Fig.14 Each toggle unit shown also includes: The driving shaft 37 is slidably mounted on one of the parallel arms 29. A mounting arm 38 is mounted on the rear end of the driving shaft 37. A sliding track that cooperates with the mounting arm 38 is arranged on the sealing ring 7. A ball bearing is mounted on the front end of the driving shaft 37. A control spring 39 is sleeved outside the driving shaft 37 and is disposed between the parallel arm 29 and the mounting arm 38. The control spring 39 drives the driving shaft 37 to move toward the annular cavity 15. A plurality of interference ring members 40 are arranged side by side and spaced apart on the mounting arm 38. The number of the plurality of interference ring members 40 is consistent with the number of the plurality of conveying platforms 32. Under normal conditions, each interference ring member 40 is arranged on one side of the nozzle. Each interference ring 40 comprises: An annular member 401 is disposed on the mounting arm 38, and a plurality of open areas are provided in a circular array on the annular member 401; A plurality of toggle plates 402 are rotatably disposed in the plurality of open areas; It is worth noting that: when the multiple toggle units rotate in a circle at the same time, the driving shaft 37 slides and fits with the inner wall of the annular cavity 15. During the rotation, the ball on the driving shaft 37 contacts the extrusion platform 16, and is guided by the inclined surface of the extrusion platform 16 to complete the movement, so that the driving shaft 37 overcomes the control spring 39 to move, so that the mounting arm 38 and the multiple interference rings 40 thereon move with it, so that the interference ring 40 moves to the nozzle area to complete the interference, and can interfere with the inert gas, so that the gas can be fully released to avoid accumulation at the nozzle, further improving the contact efficiency between the gas and the raw water. At the same time, multiple toggle plates 402 are arranged on the interference ring 40. When the interference ring 40 moves to the nozzle, the toggle plate 402 rotates due to the impact of the gas, which can guide the gas so that the gas can diffuse toward different positions, further improving the replacement efficiency of the gas. like Figure 6 and Figure 7 As shown, in the embodiment of the present invention, the ventilation mechanism includes: The hollow sleeve 17 is rotatably disposed at the center of the isolation ring 8; The breathable membrane 18 is rotatably disposed on the upper surface of the isolation ring 8. The breathable membrane 18 is composed of a fixed frame and a water-proof breathable membrane, and a one-way bearing 19 is disposed between the breathable membrane 18 and the hollow sleeve 17; The arc-shaped push groove 20 is formed on the inner wall of the hollow sleeve 17. The arc-shaped push groove 20 is designed to be arc-shaped as a whole, and can control the breathable membrane 18 to complete the rotation control; A rectangular frame 21 is arranged on the lower surface of the tank cover 5 corresponding to the exhaust passage 9. A rectangular sliding area 22 is provided in the rectangular frame 21. A gas delivery pipe is connected and installed on the top of the rectangular frame 21. A detector 23 is installed on the top of the rectangular frame 21. The detector 23 is specifically a gas detector, which can complete the detection of the type of exhaust gas. A rectangular pressing plate 24 is slidably disposed in the rectangular sliding area 22 to complete auxiliary pressing of the breathable membrane 18. A plurality of return springs are disposed in the rectangular sliding area 22. The rectangular pressing plate 24 is pulled upward in the rectangular sliding area 22 by the return springs, and two protrusions are symmetrically disposed at the bottom of the rectangular pressing plate 24. The control arm 25 is arranged on the control mechanism to complete the active control of the rectangular pressing plate 24. Under normal conditions, the control arm 25 contacts the protrusion to press the rectangular pressing plate 24. It is worth noting that when the gas is discharged: by providing a ventilation mechanism, during the gas replacement, the precipitated gas is discharged through the exhaust channel 9, and the gas is precipitated and sent into the space formed by the rectangular frame 21 through the breathable membrane 18, and the isolation of the raw water is completed. At the same time, the gas entering the rectangular frame 21 is detected by the detector 23, and the state of the gas can be detected 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 the inert gas is stopped. At the same time, a rectangular pressing plate 24 is provided on the rectangular frame 21. Under normal conditions, the control arm 25 presses the rectangular pressing plate 24 so that the rectangular pressing plate 24 is close to the breathable membrane 18 to ensure the circulation of the gas. Due to the design of the rectangular frame 21 and the rectangular pressing plate 24, the rectangular frame 21 is isolated from the processing space 11. Therefore, the inert dry gas is introduced and drawn out through the drying inlet pipe 12 and the drying outlet pipe 13, and the breathable membrane 18 can be actively cleaned to avoid a large amount of raw water remaining on the breathable membrane 18 and affecting the use effect.

[0027] Embodiment 3: Based on the control mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the control mechanism.

[0028] like Figure 8 and Fig. 9 As shown, the control mechanism includes: The electric push rod 26 is arranged on the tank cover 5; The control shaft 27 is arranged at the output end of the electric push rod 26, and the control shaft 27 slides through the hollow sleeve 17 accordingly, the bottom of the control shaft 27 is rotatably connected to the center platform 14, and the control shaft 27 is fixedly connected to the control arm 25, and the position control of the control arm 25 is completed by the control shaft 27; The trigger protrusion 28 is fixedly disposed on one side of the control shaft 27, and the trigger protrusion 28 is correspondingly slidably engaged in the arc-shaped push groove 20, and the switching of the breathable membrane 18 is completed by the cooperation between the trigger protrusion 28 and the arc-shaped push groove 20; It is worth noting that when the treated raw water is controlled to be discharged: by providing a control mechanism, after a single treatment is completed, the electric push rod 26 is started, the control shaft 27 and the sealing ring 7 are pulled upward as a whole, so that the conical material chamber 6 is opened, and 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. In the upward movement path of the control shaft 27, the control arm 25 moves upward and separates from the protrusion, and the rectangular pressure plate 24 is moved upward by the reset spring and separated from the breathable membrane 18, which is beneficial to the subsequent rotation of the breathable membrane 18, and then drives the trigger protrusion 28 to move upward synchronously. When the trigger protrusion 28 moves upward, it is restricted by the arc-shaped push groove 20. At this time, the one-way bearing 19 is in a locked state, so that The hollow sleeve 17 rotates, and the breathable membrane 18 rotates synchronously, so that the breathable membrane 18 in the clean area is transferred to the exhaust channel 9 area for replacement and use. When the control shaft 27 and the sealing ring 7 move upward, the second friction ring 48 is pulled upward to frictionally contact with the first friction ring 46 to complete the power connection, which is beneficial to the subsequent discharge work. When the subsequent electric push rod 26 drives the control shaft 27 to move down and reset, the control arm 25 moves down to reset the rectangular pressure plate 24 and press the breathable membrane 18. However, the one-way bearing 19 rotates without power transmission, so that the hollow sleeve 17 completes the self-rotation reset without interfering with the breathable membrane 18, and the first friction ring 46 is separated from the second friction ring 48 to complete the power interruption; like Fig.11 As shown, in the embodiment of the present invention, the discharge mechanism includes: A circular filter cartridge 41 is connected and arranged at the bottom of the conical material chamber 6. A plurality of filter holes are arranged in a circular array around the circular filter cartridge 41. A discharge pipe 42 is connected and installed at the bottom of the circular filter cartridge 41. The discharge pipe 42 is connected to an external waste tank. The discharge auger 43 is rotatably arranged in the discharge pipe 42 through a bracket, and a plurality of scrapers 44 are arranged in the circular filter cartridge 41, and the plurality of scrapers 44 are jointly connected to the top of the discharge auger 43 by transmission; The connecting piece is arranged between the sealing ring 7 and the circular filter cartridge 41 to complete the power connection; In an embodiment of the present invention, the connecting piece includes: A mounting frame 45 is arranged on the top of the discharge auger 43, and a first friction ring 46 is arranged on the mounting frame 45 through a bracket; The sliding rod 47 is arranged 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, and the power connection control is completed through the friction contact between the second friction ring 48 and the first friction ring 46; It is worth mentioning that when the treated raw water is purified: a discharge mechanism is provided, when the No. 1 friction ring 46 and the No. 2 friction ring 48 complete the power connection, the rotating motor 36 is started to rotate the sealing ring 7. Since the No. 1 friction ring 46 and the No. 2 friction ring 48 are in friction contact, the rotational force is transmitted to the multiple scrapers 44 and the discharge auger 43. The circular filter cartridge 41 is scraped and cleaned by the multiple scrapers 44 to avoid blockage during the release of raw water. At the same time, the impurities accumulated in the circular filter cartridge 41 are discharged through the discharge pipe 42 by the discharge auger 43 to complete self-cleaning, avoid impurity accumulation, and reduce the difficulty of cleaning.

[0029] Embodiment 4: A method for separating ultrapure water based on a solar thermal power station, the method for separating ultrapure water specifically comprising the following steps: Step 1: The sealing ring 7 is driven downward by the control mechanism to seal the annular cavity 15, and the raw water is sent into the replacement space 10 to wait for treatment; Step 2: Inert gas is sent into the replacement space 10, and multiple points of synchronous release are completed through multiple toggle units, so that the inert gas enters the raw water to complete the replacement; Step 3: By providing a ventilation mechanism, the gas discharged during the replacement can be precipitated; Step 4: The impurities generated during the treatment process are discharged through the provided discharge mechanism.

[0030] The present invention provides an ultrapure water separation device and method based on a photothermal power station. The specific working principle is as follows: first, the sealing ring 7 is driven downward by a control mechanism to seal the annular cavity 15, and then the raw water is sent into the displacement space 10, and the inert gas is sent into the annular material cavity 34. The multi-point synchronous release is completed through multiple toggle units, so that the inert gas enters the raw water to complete the replacement, effectively reducing the carbon dioxide content in the raw water, which is beneficial to the control of the conductivity of the raw water. At the same time, the sealing ring 7 and the multiple toggle units can complete the rotation, and the raw water in the displacement space 10 is completed. At the same time, the treatment agent can be added according to the amount of raw water, so that the treatment agent can be fully mixed with the raw water, and the carbon dioxide and impurities in the raw water can be controlled to complete the replacement. The multi-mode treatment of raw water reduces the workload of subsequent raw water treatment and improves the treatment accuracy and efficiency. By providing a breathable mechanism, the gas discharged during the replacement can be precipitated and detected. At the same time, the control mechanism can synchronously control the breathable mechanism and the discharge mechanism during operation, thereby realizing the dynamic connection between the breathable mechanism and the discharge mechanism, so that the breathable mechanism can complete a switch in a single treatment process, so that the breathable mechanism maintains a good separation state. At the same time, the design of the discharge mechanism can quickly separate and discharge flocculated impurities in the raw water, reducing the subsequent cleaning workload, and the discharge mechanism can be dynamically separated from the sealing ring 7, effectively reducing the load, making the equipment operation more stable and extending the service life.
