Description

Technical Field

[0001] This invention relates to the field of ice storage and provides a device for promoting crystallization and concentration of supercooled water. Background Technology

[0002] The statements herein are provided only as background information in connection with this application and do not necessarily constitute prior art.

[0003] Ice slurry is a solid-liquid two-phase fluid formed by a mixture of tiny ice crystals. It is characterized by good fluidity, rapid cooling release, and high energy storage per unit weight, making it ideal for use as a cold storage medium. Ice slurry cold storage systems typically utilize off-peak electricity at night or unconnected sources to drive ice-making units to generate ice slurry. The generated ice slurry is then pumped into ice storage tanks for storage, and the cooling capacity is released during peak daytime electricity demand by melting the ice. Compared to traditional static ice storage (such as ice balls or ice buildup on the outer wall of coils), ice slurry energy storage exhibits significant advantages in energy efficiency and economy due to its excellent fluidity and high latent heat of phase change. However, ice slurry energy storage systems also face a series of challenges that limit their large-scale application.

[0004] Specifically, there are two major challenges in the ice slurry cooling process: first, how to achieve a continuous and stable cooling process; and second, how to overcome the risk of ice blockage. Since ice slurry crystal production is an unsteady thermodynamic process, continuous ice production is necessary to achieve a stable release of waste cooling energy, and to overcome the potential differences in crystallization effects caused by unstable cooling. Once ice crystals accumulate and clump in the cooling pipes, ice blockage will occur, severely affecting system reliability. The ice slurry production temperature is generally not lower than 4°C, and the amount of ice produced in each ice-making cycle generally does not exceed 0°C. Under current technological conditions, most of the water needs to enter the ice storage tank to achieve ice-water separation, resulting in high flow rate and resistance in the water system. Summary of the Invention

[0005] This invention provides a supercooled water crystallization concentration device to solve the defects of related technologies, such as the need for additional energy in the crystallization process, unstable operation, and susceptibility to ice blockage.

[0006] This invention provides a supercooled water crystallization concentration device, including a base plate, a rotating wheel, a filter screen, and a drive assembly; The top surface of the base plate is conical, and the base plate has at least one downward opening as an ice outlet; The rotating wheel is disposed above the base plate, and the drive assembly is connected to the rotating wheel to drive the rotating wheel to rotate around the central axis; The impeller includes multiple radial plates, which divide the space inside the impeller into multiple fan-shaped regions. A subcooled water inlet is provided above the base plate at a position corresponding to one or more of the fan-shaped regions. The filter screen is installed on the side of the impeller to form a water outlet; the bottom of the radial plate is disposed close to the top surface of the base plate so that when the impeller rotates, it pushes the ice-water mixture that flows in from the subcooled water inlet and impacts the crystallization generated on the surface of the base plate to slide along the surface of the base plate. The water in the ice-water mixture is discharged through the filter screen on the side of the impeller, and the concentrated ice crystals are pushed to the ice outlet by the radial plate and discharged downwards by gravity.

[0007] According to one embodiment of the present invention, the subcooled water inlet and the ice outlet are offset from each other to increase the crystallization and sliding drainage path of the subcooled water on the surface of the base plate.

[0008] According to one embodiment of the present invention, the side of the rotating wheel is provided with an outer frame, and the filter screen is detachably mounted on the outer frame.

[0009] According to one embodiment of the present invention, the rotating wheel has a rotating shaft at its center, and a filter screen window is provided on the bottom surface of the rotating wheel and / or the outer frame, and the filter screen is installed at the filter screen window.

[0010] According to one embodiment of the present invention, the supercooled water crystallization concentration device further includes a water tank, which is disposed outside the rotor and directly opposite the water outlet on the side of the rotor, for collecting water discharged through the filter screen.

[0011] According to one embodiment of the present invention, the bottom or side wall of the water tank is provided with a circulation outlet, which is used to transport the collected water to an external ice-making circulation system for re-making ice.

[0012] According to one embodiment of the present invention, the radial plates extend outward along the radial direction of the rotating wheel, and two adjacent radial plates together with the outer edge of the rotating wheel form a vertically continuous fan-shaped area.

[0013] According to one embodiment of the present invention, the top surface of the base plate slopes downward from the center to the outer edge to form a cone shape, so as to guide the water in the ice-water mixture to flow and drain out towards the filter screen on the side of the impeller under the action of gravity.

[0014] According to one embodiment of the present invention, the outer edge of the base plate is provided with an upwardly protruding sidewall, the sidewall and the base plate together forming an accommodating cavity with an upper opening, and the rotating wheel is rotatably engaged in the accommodating cavity.

[0015] According to one embodiment of the present invention, the drive assembly includes a motor for driving the wheel to rotate.

[0016] The supercooled water crystallization and concentration device provided in this embodiment of the invention adopts a physical crystallization method of supercooled water impacting the bottom plate and inducing crystal nuclei from residual crystals, replacing the traditional ultrasonic crystallization technology. The crystallization process is not affected by water quality and temperature fluctuations, and the reaction is rapid and highly controllable, enabling safe crystallization of supercooled water at almost all supercooling degrees. The crystallization and separation processes are completed entirely inside the device, avoiding the agglomeration of ice crystals in the conveying pipeline, eliminating the risk of ice blockage at the source, and significantly improving the reliability of system operation. The rotor divides the space into multiple independent fan-shaped areas through radial plates, which can simultaneously complete the entire continuous process of supercooled water inflow, impact crystallization, sliding drainage, ice crystal concentration, and automatic ice removal, with high processing efficiency and no need for manual intervention. The device has no easily clogged spirals, scrapers, or complex filter structures. During operation, the concentrated large ice crystals will move and discharge the small ice crystals attached to the filter screen, achieving self-cleaning of the filter screen, effectively avoiding filter screen blockage, and ensuring long-term stable operation. This technology departs from the traditional method where most water enters the ice storage tank before separation. Instead, ice-water separation is achieved directly within the crystallization unit, with only concentrated ice crystals entering the storage tank. This reduces the amount of water entering the storage tank by over 70%, significantly decreasing the water system's flow rate and pipe resistance. Simultaneously, the smooth surface of the conical base plate minimizes the sliding resistance of the ice crystals, requiring minimal power from the rotor to move them. The overall energy consumption of this device is only 1 / 3 and 1 / 5 of that of traditional spiral and scraper separation devices, respectively. The conical base plate utilizes gravity to guide water flow towards the outer filter screen, combined with centrifugal force during the sliding process, resulting in high drainage efficiency. By extending the sliding path of the ice-water mixture, thorough solid-liquid separation is achieved. Tests show that the IPF (ice volume fraction) of the ice crystals can be increased by more than 3 times, significantly increasing the cold storage density of the ice slurry and reducing the volume requirement of the ice storage tank. The core components of the device are only the base plate, the rotating wheel, the filter screen, and the drive motor. There are no complex transmission mechanisms or vulnerable parts. The structure is simple, the processing cost is low, and the operating noise is low. The filter screen adopts a detachable design, which is convenient for regular cleaning or replacement, making maintenance convenient and suitable for the long-term continuous operation requirements of industrial-grade large-scale ice slurry cold storage systems.

[0029] like Figures 1 to 5 As shown, this embodiment of the invention provides a supercooled water crystallization concentration device, including a base plate 100, a rotating wheel 104, a filter screen 106, and a drive assembly; The top surface of the base plate 100 is conical, and the base plate 100 has at least one downward opening as an ice outlet 102. The rotating wheel 104 is disposed above the base plate 100, and the drive assembly is connected to the rotating wheel 104 in a transmission connection to drive the rotating wheel 104 to rotate around the central axis; The rotor 104 includes multiple radial plates 108, which divide the space inside the rotor 104 into multiple fan-shaped regions. A subcooled water inlet 110 is provided above the base plate 100 at the position corresponding to one of the fan-shaped regions. A filter screen 106 is installed on the side of the rotor 104 to form a water outlet 112; The bottom of the radial plate 108 is disposed close to the top surface of the base plate 100 so that when the wheel 104 rotates, it pushes the ice-water mixture that flows in from the supercooled water inlet 110 and impacts the crystal-promoting agent generated on the surface of the base plate 100 to slide along the surface of the base plate 100. In this process, the water in the ice-water mixture is discharged through the filter screen 106 on the side of the rotor 104, and the concentrated ice crystals are pushed to the ice outlet 102 by the radial plate 108 and discharged downwards by gravity.

[0030] The supercooled water crystallization and concentration device provided in this embodiment of the invention adopts a physical crystallization method of supercooled water impacting the bottom plate 100 and inducing crystal nuclei from residual crystals, replacing the traditional ultrasonic crystallization technology. The crystallization process is not affected by water quality and temperature fluctuations, and the reaction is rapid and highly controllable, enabling safe crystallization of supercooled water at almost all supercooling degrees. The crystallization and separation processes are completed entirely inside the device, avoiding the agglomeration of ice crystals in the conveying pipeline, eliminating the risk of ice blockage at the source, and significantly improving the reliability of system operation. The rotor 104 divides the space into multiple independent fan-shaped areas through radial plates 108, which can simultaneously complete the entire continuous process of supercooled water inflow, impact crystallization, sliding drainage, ice crystal concentration, and automatic ice removal, with high processing efficiency and no need for manual intervention. The device has no easily clogged spirals, scrapers, or complex filter structures. During operation, the large ice crystals after concentration will move and discharge the small ice crystals attached to the filter screen 106, realizing the self-cleaning of the filter screen 106, effectively avoiding filter screen blockage, and ensuring long-term stable operation. This technology departs from the traditional method where most water enters the ice storage tank before separation. Instead, ice-water separation is achieved directly within the crystallization device, with only concentrated ice crystals entering the ice storage tank. This reduces the amount of water entering the tank by over 70%, significantly decreasing the water system's flow rate and pipe resistance. Simultaneously, the smooth surface of the conical base plate 100 minimizes the sliding resistance of the ice crystals, requiring minimal power from the rotor 104 to move them. The overall energy consumption of this device is only 1 / 3 and 1 / 5 of that of traditional spiral and scraper separation devices, respectively.

By extending the sliding path of the ice-water mixture, thorough solid-liquid separation is achieved. Tests show that the IPF (ice volume fraction) of the ice crystals can be increased by more than 3 times, significantly increasing the cold storage density of the ice slurry and reducing the volume requirement of the ice storage tank. The core components of the device are only the base plate 100, the rotating wheel 104, the filter screen 106 and the drive motor. There are no complex transmission mechanisms or vulnerable parts. The structure is simple, the processing cost is low and the operating noise is low. The filter screen 106 adopts a detachable design, which is convenient for regular cleaning or replacement, and the maintenance is convenient. It is suitable for the long-term continuous operation requirements of industrial-grade large-scale ice slurry cold storage systems.

[0031] Please continue reading Figures 1 to 5 The supercooled water crystallization and concentration device provided in this embodiment of the invention is an ice slurry treatment device that integrates supercooled water impact crystallization, continuous solid-liquid separation, and automatic ice crystal concentration and discharge.

[0032] The base plate 100 serves as the basic support and crystallization reaction substrate of the device. Its top surface has an overall conical structure with a high center and low edges. The base plate 100 has at least one through-hole as an ice outlet 102 for discharging concentrated ice crystals. The surface of the base plate 100 is a smooth and hard surface, which can withstand the high-speed impact of supercooled water and reduce the frictional resistance when ice crystals slide.

[0033] The rotating wheel 104 is the core conveying and separating component of the device, and is coaxially arranged directly above the base plate 100. The drive assembly is connected to the center of the rotating wheel 104 and can drive the rotating wheel 104 to rotate at a constant speed around its own vertical central axis. Multiple radial plates 108 are evenly arranged circumferentially inside the rotating wheel 104. The radial plates 108 extend radially along the rotating wheel 104 and divide the annular space inside the rotating wheel 104 into multiple independent, vertically connected fan-shaped areas. A subcooled water inlet 110 is fixedly arranged above the base plate 100 at the position corresponding to one of the fan-shaped areas. Subcooled water is sprayed vertically downward from this inlet onto the surface of the base plate 100.

[0034] The filter screen 106 is fixedly installed on the entire circumferential side of the rotor 104, forming an annular water outlet 112 around the rotor 104; the pore size of the filter screen 106 is smaller than the particle size of the ice crystals to be separated, allowing liquid water to pass through but blocking ice crystal particles.

[0035] The bottom edge of the radial plate 108 maintains a small gap (closely positioned) with the conical top surface of the base plate 100, which ensures that the rotating wheel 104 can rotate freely, and when the rotating wheel 104 rotates, the side of the radial plate 108 pushes the ice-water mixture that flows in from the supercooled water inlet 110 and impacts the surface of the base plate 100 to form a crystal-promoting mixture, causing it to slide circumferentially along the conical surface of the base plate 100.

[0036] The working process of the supercooled water crystallization concentration device provided in this embodiment of the invention is as follows: Supercooled water is sprayed at high speed from the supercooled water inlet 110 onto the surface of the base plate 100. Utilizing its own impact kinetic energy and the ice crystals remaining on the surface of the base plate 100 as nuclei, the crystallization reaction is completed instantaneously, generating an ice-water mixture. The rotating wheel 104 drives the radial plate 108 to push the ice-water mixture along the surface of the conical base plate 100 towards the ice outlet 102. During the sliding process, the liquid water in the ice-water mixture flows to the outside of the rotating wheel 104 under the combined action of gravity and centrifugal force and is discharged through the side filter screen 106, achieving solid-liquid separation. As water is continuously discharged, the ice crystal concentration in the ice-water mixture gradually increases, forming concentrated ice crystals. Finally, the concentrated ice crystals are pushed to the ice outlet 102 by the radial plate 108 and automatically discharged downwards under gravity, completing the entire crystallization and concentration process.

[0037] According to one embodiment of the present invention, the supercooled water inlet 110 is located above the fan-shaped area on the side away from the ice outlet 102, so as to increase the crystallization and sliding drainage path of the supercooled water on the surface of the base plate 100, thereby increasing the ice content of the ice slurry at the ice outlet 102.

[0038] In one embodiment of the present invention, the supercooled water inlet 110 is located directly above the fan-shaped area on the side away from the ice outlet 102, so that after the supercooled water flows in, it needs to travel a path of nearly one revolution with the wheel 104 to reach the ice outlet 102, thereby maximizing the time for the supercooled water to promote crystallization reaction on the surface of the base plate 100 and the length of the sliding drainage path.

[0039] The extended crystallization and drainage path allows the supercooled water to fully contact the surface of the base plate 100 and the ice crystals remaining on the filter screen. It utilizes the impact kinetic energy of the supercooled water itself and the crystal nucleation induction effect to achieve rapid and stable crystallization, avoiding the risk of ice blockage caused by insufficient crystallization. At the same time, the longer gliding time allows the water in the ice-water mixture to be discharged more fully through the filter screen 106, significantly improving the concentration ratio of ice crystals. Tests show that it can achieve an increase of more than 3 times in ice crystal IPF (ice volume fraction).

[0040] According to one embodiment of the present invention, the side of the rotating wheel 104 is provided with an outer frame 116, and the filter screen 106 is detachably mounted on the outer frame 116.

[0041] In one embodiment of the present invention, the side of the rotating wheel 104 is provided with an annular outer frame 116 along the circumferential direction. The outer frame 116 is provided with an installation port corresponding to each fan-shaped area. The filter screen 106 is detachably installed in the installation port by means of snap-fit ​​connection or bolt connection. The edge of the filter screen 106 is sealed and fitted with the outer frame 116 to prevent unfiltered ice water mixture from overflowing from the gap.

[0042] The detachable filter screen 106 design facilitates regular disassembly, cleaning, or replacement by staff, effectively solving the problem of filter screen 106 being clogged by ice crystals and ensuring long-term filtration performance. Simultaneously, filter screens 106 with corresponding pore sizes can be replaced according to the processing requirements of ice crystals of different particle sizes, improving the versatility and adaptability of the device. Furthermore, during the rotation of the rotor 104, which propels the ice crystals, the concentrated large ice crystals will carry the small ice crystals attached to the filter screen 106 along with it, ultimately discharging them from the ice outlet 102, achieving self-cleaning of the filter screen 106 and effectively extending its cleaning cycle.

[0043] According to one embodiment of the present invention, the rotating wheel 104 has a rotating shaft at its center, and a filter window 114 is provided on the bottom surface and / or the outer frame 11 of the rotating wheel 104, and a filter 106 is installed at the filter window 114.

[0044] In one embodiment of the present invention, a rotating shaft is vertically fixed at the center of the rotating wheel 104, and at least one filter screen window 114 is provided on the bottom surface of the rotating wheel 104 and / or the side wall of the rotating shaft. A filter screen 106 is fixedly installed at each filter screen window 114. The aperture of the filter screen 106 is consistent with the aperture of the filter screen 106 on the side of the rotating wheel 104, so as to simultaneously filter and discharge water in the ice-water mixture from the bottom and center of the rotating wheel 104, forming a multi-directional synchronous filtration structure.

[0045] By adding filter screen windows 114 and filter screen 106 to the bottom surface of the rotor 104 and the shaft, the total filtration area of ​​the device is greatly increased, which can significantly improve the water separation speed and adapt to the needs of higher flow rate subcooled water treatment; multi-directional simultaneous filtration can avoid the problem of poor drainage caused by clogging of single-directional filtration, further improve the ice crystal concentration efficiency, and ensure that the device can still operate stably under high flow rate conditions.

[0046] According to one embodiment of the present invention, the supercooled water crystallization concentration device further includes a water tank, which is disposed outside the rotor 104 and directly opposite the water outlet 112 on the side of the rotor 104, for collecting water discharged through the filter screen 106.

[0047] In one embodiment of the present invention, the supercooled water crystallization concentration device further includes an annular water tank, which is arranged around the outside of the rotor 104, and the opening of the water tank is directly opposite all the water outlets 112 on the side of the rotor 104 (i.e., the location of the filter screen 106). The bottom of the water tank is lower than the lower edge of the filter screen 106, so as to completely receive all the water discharged through the filter screen 106 and prevent water from spilling.

[0048] The annular water tank can collect water discharged from all sides of the rotor 104 from all directions, preventing water from spilling onto the outside of the device and keeping the working environment clean and dry. The collected water is easy to treat and recycle, avoiding water waste, and at the same time preventing water accumulation from causing corrosion of device parts and extending the service life of the device.

[0049] According to one embodiment of the present invention, the bottom or side wall of the water tank is provided with a circulation outlet for conveying the collected water to an external ice-making circulation system for re-making ice.

[0050] In one embodiment of the present invention, a circulating water outlet is provided at the lowest position of the bottom or side wall of the water tank. The circulating water outlet is connected to the water inlet of an external ice-making circulation system through a sealed connecting pipe, so as to continuously and stably transport the unfrozen water collected in the water tank to the external ice-making circulation system for re-extraction of subcooled water.

[0051] By achieving closed-loop recycling of unfrozen water through the circulating outlet, the system's water consumption is significantly reduced, and water resource utilization is improved. At the same time, the amount of water that needs to enter the ice storage tank for separation is reduced, significantly reducing the flow rate and resistance of the water system, and improving the operating efficiency and economy of the entire ice slurry cold storage system.

[0052] According to one embodiment of the present invention, the radial plates 108 extend outward along the radial direction of the rotating wheel 104, and two adjacent radial plates 108 together with the outer edge of the rotating wheel 104 form a vertically continuous fan-shaped area.

[0053] In one embodiment of the present invention, the radial plates 108 extend outward from the central axis along the radial direction of the rotating wheel 104 to the outer edge of the rotating wheel 104, and multiple radial plates 108 are evenly distributed around the circumference of the rotating wheel 104; two adjacent radial plates 108, the outer edge of the rotating wheel 104, and the upper and lower end faces of the rotating wheel 104 together form an independent fan-shaped area that runs vertically through each other, and each fan-shaped area can independently accommodate and transport the ice-water mixture without interfering with each other.

[0054] The uniformly distributed fan-shaped areas enable continuous batch processing of subcooled water, ensuring uninterrupted operation of the device and improving processing efficiency. The vertically connected structure facilitates the inflow of subcooled water from above and the discharge of ice crystals from the ice outlet 102 below, while also promoting the flow of water towards the side filter screen 106 under gravity. The independent fan-shaped areas prevent the mixing of ice-water mixtures from different processing stages, ensuring the stability and consistency of the crystallization and concentration processes.

[0055] According to one embodiment of the present invention, the top surface of the base plate 100 is inclined downward from the center to the outer edge to form a cone shape, so as to guide the water in the ice-water mixture to flow and drain out towards the filter screen 106 on the side of the wheel 104 under the action of gravity.

[0056] In one embodiment of the present invention, the top surface of the base plate 100 is inclined downward at a small angle of 3° or 10° from the center to the outer edge to form a conical structure; the lowest point of the top surface of the conical shape is flush with the lower edge of the filter screen 106 on the side of the rotating wheel 104, which is used to guide the water in the ice-water mixture to flow automatically towards the filter screen 106 on the side of the rotating wheel 104 under the action of gravity and drain out.

[0057] The conical base plate 100 utilizes gravity to assist in drainage, accelerating the separation of water and ice crystals without requiring additional power, thus reducing the energy consumption of the device. The small-angle tilt design ensures smooth water flow without causing ice crystals to slide quickly towards the filter screen 106 along with the water, guaranteeing sufficient drainage time. The design of the inclined surface being flush with the edge of the filter screen 106 ensures that all separated water can enter the filter screen 106 for discharge, improving separation efficiency. At the same time, the contact resistance between the smooth conical base plate 100 and the ice crystals is very small, and the power required for the rotor 104 to move the ice crystals is extremely low, significantly reducing the overall operating energy consumption of the device.

[0058] According to one embodiment of the present invention, the outer edge of the base plate 100 is provided with an upwardly protruding sidewall, and the sidewall and the base plate 100 together form an accommodating cavity with an upper opening, and the rotating wheel 104 is rotatably engaged in the accommodating cavity.

[0059] In one embodiment of the present invention, the outer edge of the base plate 100 is provided with an upwardly protruding annular sidewall along the circumferential direction. The height of the sidewall is higher than the highest point of the top surface of the base plate 100. The sidewall and the base plate 100 together form a cylindrical cavity with an opening at the top. The outer diameter of the rotating wheel 104 is slightly smaller than the inner diameter of the cavity. A small gap is left between the bottom of the rotating wheel 104 and the top surface of the base plate 100. The rotating wheel 104 can rotate freely around the central axis within the cavity.

[0060] The annular sidewall effectively prevents the ice-water mixture from overflowing from the edge of the base plate 100, ensuring that all the ice-water mixture can be pushed by the radial plate 108 and filtered by the filter screen 106, thereby improving the recovery rate of ice-water separation. The accommodating cavity plays a radial limiting and guiding role for the rotor 104, ensuring the coaxiality and stability of the rotor 104 during rotation, and avoiding friction between the radial plate 108 and the base plate 100 or leakage of the ice-water mixture caused by the rotor 104 shaking. The micro-gap design can prevent ice crystals from getting stuck between the rotor 104 and the base plate 100, ensuring smooth rotation of the rotor 104.

[0061] According to one embodiment of the present invention, the drive assembly includes a motor for driving the rotating wheel 104 to rotate.

[0062] In one embodiment of the present invention, the drive component includes a geared motor, and the rotation speed can be adjusted according to the processing flow rate requirements.

[0063] The top-mounted motor installation method has a compact structure and does not occupy the space below the base plate 100, which facilitates the arrangement of the ice outlet 102 and the collection and discharge of ice crystals. The geared motor can provide stable torque and adjustable rotation speed to adapt to different processing flow requirements. The direct drive transmission structure is simple, with high transmission efficiency, low operating noise, low failure rate, and convenient maintenance. At the same time, the processing time of the ice-water mixture can be adjusted by controlling the motor speed, and the concentration of ice crystals can be flexibly adjusted to meet the needs of different working conditions.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
