Description

Technical Field

[0001] This invention relates to the field of supercooled water ice-making technology, and more specifically, to an ice crystal eliminator and a supercooled water ice-making system. Background Technology

[0002] A conventional subcooled water ice-making system (also known as a subcooled water dynamic ice-making system) mainly consists of a subcooler 101, a subcooling removal device 102, an ice storage tank 103, a preheater 104, and a filter device 105, such as... Figure 1 As shown. In this system, preheated water (2°C) enters the subcooler through pipes to exchange heat with the refrigerant, becoming subcooled water (…). 2℃). Then cool with cold water ( The water (2°C) is fed to a subcooling removal device, where its subcooled state is broken, becoming an ice-water mixture (0°C) that enters an ice storage tank. Ice and water separation occurs in the ice storage tank; the separated ice is collected and utilized, while the cold water (0°C) continues to circulate in the system. To ensure the normal operation of the subcooler, it is necessary to prevent ice crystals from entering its interior. However, the ice-water separation described above can only remove some ice crystals; the cold water (0°C) circulating in the system still contains a large number of tiny ice crystals, so ice crystal removal treatment is required. Current conventional methods mainly use a preheater to raise the temperature of the cold water (0°C) to melt the tiny ice crystals. The cold water (0°C) heated by the preheater becomes preheated water (2°C) and enters a filtration device for another ice-water separation, finally entering the subcooler for the next cycle.

[0003] In the above process, the elimination of micro-ice crystals mainly relies on heating by preheater 104. This method has two main problems. First, the temperature of the preheated water (2℃) entering the subcooler cannot be too high. Therefore, relying solely on the preheater cannot quickly eliminate micro-ice crystals in the cold water (0℃). Improvement can only be achieved by increasing the number of preheaters and significantly extending the tube path, but the improvement effect is not ideal. Second, to ensure the elimination of micro-ice crystals in the cold water (0℃), it must be heated to a higher temperature. This approach will increase the heat exchange performance requirements of the preheater, and simultaneously, the preheated water (2℃) and the subcooled water (… The increased temperature difference (2℃) leads to a significant increase in the workload of the supercooler, resulting in a decrease in system energy efficiency.

[0004] In summary, the existing subcooled water ice-making system has poor ice crystal removal effect and low system energy efficiency. Summary of the Invention

[0005] This invention provides an ice crystal eliminator and a supercooled water ice-making system to solve the problems of poor ice crystal elimination effect and low system energy efficiency in the existing supercooled water ice-making system.

[0006] To achieve the above objectives, the present invention provides an ice crystal eliminator, comprising: a housing having a mixing chamber; a cold water pipe communicating with the mixing chamber, wherein the cold water pipe introduces cold water containing ice crystals into the mixing chamber; a preheating water pipe communicating with the mixing chamber, wherein the preheating water pipe introduces preheated water into the mixing chamber, wherein the preheated water and the cold water containing ice crystals collide and mix within the mixing chamber; and a water outlet pipe communicating with the mixing chamber, wherein the water outlet pipe discharges the mixed water from the mixing chamber.

[0007] Furthermore, it also includes: a baffle plate, which is disposed in the mixing chamber and forms a baffle channel, through which preheated hot water and cold water collide and mix and flow out of the mixing chamber.

[0008] Furthermore, it also includes: an inner cylinder body disposed within the mixing chamber, the inner cylinder body dividing the mixing chamber into an inner chamber and an outer chamber, the inner chamber being formed inside the inner cylinder body, and the outer chamber being formed between the inner cylinder body and the shell; a connecting hole is provided on the inner cylinder body, through which the inner chamber and the outer chamber are connected; a cold water pipe is disposed on the shell, the cold water pipe being connected to the outer chamber, the preheated hot water pipe being connected to the inner chamber, and a baffle plate being disposed in the inner chamber.

[0009] Furthermore, there are multiple baffles, which are spaced apart in the inner cavity.

[0010] Furthermore, the housing has an elimination chamber, which is adjacent to the mixing chamber; the ice crystal eliminator also includes a spiral partition structure, which is disposed in the elimination chamber and forms a spiral flow channel, which is connected to the mixing chamber; the water outlet pipe is connected to the spiral flow channel, and the mixed water in the mixing chamber is discharged through the water outlet pipe after passing through the spiral flow channel.

[0011] Furthermore, the ice crystal eliminator also includes a first vortex generator that can rotate freely, the first vortex generator being installed inside the spiral flow channel.

[0012] Furthermore, the ice crystal eliminator also includes a first fixing rod, which passes through the spiral partition structure along the axial direction of the spiral flow channel. The first fixing rod forms multiple mounting sections within the spiral flow channel, and the first vortex generator is rotatably connected to the mounting section. The first vortex generator can rotate on its own and can rotate circumferentially around the mounting section.

[0013] Furthermore, the preheated water pipe passes through both the elimination chamber and the mixing chamber, with the port of the preheated water pipe located within the mixing chamber; the spiral partition structure is a spiral partition plate, which is sleeved and fixedly connected to the outer circumferential surface of the preheated water pipe, and the spiral partition structure, the outer circumferential surface of the preheated water pipe, and the inner wall surface of the elimination chamber together form the spiral flow channel.

[0014] Furthermore, the housing has an elimination cavity, which is adjacent to and communicates with the mixing cavity; the ice crystal eliminator also includes a turbulence-disrupting element, which is rotatably disposed within the elimination cavity.

[0015] Furthermore, the preheated water pipe passes through both the elimination chamber and the mixing chamber, with the port of the preheated water pipe located within the mixing chamber; the turbulence-disrupting element is connected to the outer circumferential surface of the preheated water pipe via a rotating shaft.

[0016] Furthermore, the ice crystal eliminator also includes: a second fixing rod, which is fixedly connected inside the eliminator cavity; and a second vortex generator, which is rotatably mounted on the second fixing rod and is staggered from the turbulence-disrupting component.

[0019] The ice crystal eliminator in this invention introduces both preheated hot water and cold water into the mixing chamber for collision and mixing. First, the preheated water comes into contact with cold water for heat exchange, which removes tiny ice crystals in the cold water. During the intense collision between the preheated and cold water, the turbulence intensity is increased, rapidly melting these tiny ice crystals. This intense collision and thorough mixing of the preheated and cold water, utilizing the combined effects of heat exchange and turbulence, greatly accelerates the elimination of tiny ice crystals. Compared to existing technologies that rely solely on a preheater to heat the cold water, this method is more effective and faster at eliminating ice crystals. Furthermore, it achieves remarkable results without using high-temperature preheated water. By leveraging structural advantages and water flow characteristics, it significantly saves energy. This invention makes the ice-making system more energy-efficient and improves the energy efficiency of subcooled water ice-making systems. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0022] Example 1 See Figure 2 As shown, according to Embodiment 1 of the present invention, an ice crystal eliminator is provided. The ice crystal eliminator includes a housing 10, a cold water pipe 11, a preheating water pipe 12, and a water outlet pipe 13. The housing 10 has a mixing chamber 20. The cold water pipe 11 is connected to the mixing chamber 20, and the cold water pipe 11 introduces cold water containing ice crystals into the mixing chamber 20. The preheating water pipe 12 is connected to the mixing chamber 20, and the preheating water pipe 12 introduces preheated water into the mixing chamber 20. The preheated water and the cold water containing ice crystals collide and mix in the mixing chamber 20. The water outlet pipe 13 is connected to the mixing chamber 20, and the water outlet pipe 13 discharges the mixed water in the mixing chamber 20.

[0023] The ice crystal eliminator in this invention introduces both preheated and cold water into a mixing chamber for collision and mixing. The preheated water first contacts and exchanges heat with the cold water, which initially removes tiny ice crystals from the cold water. During the intense collision between the preheated and cold water, the turbulence intensity of the water flow is increased, thereby rapidly melting the tiny ice crystals in the water. The intense collision and thorough mixing of the preheated water (0.5℃) and cold water (0℃), utilizing the dual effects of heat exchange and turbulence intensity, greatly accelerates the elimination speed and effectiveness of tiny ice crystals in the water flow. Compared to existing technologies that rely solely on a preheater to heat the cold water (0℃), the ice crystal elimination effect is better and faster. Moreover, it can achieve outstanding results without using a high preheated water temperature (existing technologies use 2℃ preheated water, while this invention only uses 0.5℃). Utilizing structural advantages and water flow characteristics, it saves a significant amount of energy. The technical solution of this invention makes the ice-making system more energy-efficient and improves the energy efficiency of the subcooled water ice-making system.

[0024] The ice crystal eliminator also includes a baffle plate 21 disposed within the mixing chamber 20. The baffle plate 21 forms a baffle channel, through which preheated hot water and cold water collide and mix before flowing out of the mixing chamber 20. See also Figure 2 and 3 The preheated and cold water flow channels deflect water left and right in sequence, and flow in the direction of the arrow in the figure. The direction of water flow changes continuously, which can increase the turbulence of the water flow and further improve the ice crystal removal effect.

[0025] Furthermore, the baffled flow channel not only increases the turbulence of the water flow, but also allows the preheated and cold water to collide and mix within it. The baffled flow channel contains not only the mixed water but also the preheated and cold water. Internally, the baffled flow channel also creates a longer flow path, increasing the collision time between the preheated and cold water, thus improving the ice crystal removal rate and enhancing the ice crystal removal effect.

[0026] Preferably, there are multiple baffles 21, and the multiple baffles 21 are spaced apart in the inner cavity 20a.

[0027] It should be noted that the shape of the baffle 21 can be set according to the specific mixing chamber. In this embodiment, the mixing chamber is a cylindrical chamber. Considering the effects of sealing and baffle effect, the baffle 21 in this embodiment is fan-shaped, and multiple baffles 21 are arranged at intervals. The baffle openings of two adjacent baffles are staggered to form a baffle channel. Of course, in other embodiments not shown, the baffles and baffle channels can also be of other shapes and orientations.

[0028] Combination Figure 2 and Figure 4 As shown, the ice crystal eliminator also includes an inner cylinder 22, which is disposed in the mixing chamber 20. The inner cylinder 22 divides the mixing chamber 20 into an inner chamber 20a and an outer chamber 20b. The inner chamber 20a is formed inside the inner cylinder 22, and the outer chamber 20b is formed between the inner cylinder 22 and the shell 10. The inner cylinder 22 is provided with a connecting hole 23, and the inner cavity 20a and the outer cavity 20b are connected through the connecting hole 23; there are multiple connecting holes 23, which are evenly or unevenly distributed on the inner cylinder 22.

[0029] The cold water pipe 11 is disposed on the housing 10 and is connected to the outer chamber 20b. The preheated water pipe 12 is connected to the inner chamber 20a and the baffle plate 21 is disposed in the inner chamber 20a.

[0030] Cold water entering through cold water pipe 11 first enters the outer chamber, and then evenly enters the inner chamber through the connecting hole 23 to collide and mix with the preheated water. The function of the inner chamber is to concentrate the collision area and increase the heat exchange effect. The functions of the outer chamber and the connecting hole are twofold: first, to guide the cold water more evenly into the inner chamber, preventing the cold water from being too concentrated and causing incomplete ice crystal removal; and second, to increase the turbulence of the water flow, thus aiding in the removal of ice crystals.

[0031] It should be noted that both the inner cylinder and the outer shell are cylindrical structures, the outer chamber is an annular space, and the inner chamber is a cylindrical space.

[0032] Preferably, the housing 10 has an elimination cavity 30, which is disposed adjacent to the mixing cavity 20; The ice crystal eliminator also includes a spiral partition structure 31, which is disposed in the elimination chamber 30 and forms a spiral flow channel 32, which is connected to the mixing chamber 20; The outlet pipe 13 is connected to the spiral flow channel 32, and the mixed water in the mixing chamber 20 is discharged through the outlet pipe 13 after passing through the spiral flow channel 32.

[0033] See Figure 2 The arrow indicating the direction of the mixed water flow shows that the mixed water (0.3℃) entering the spiral flow channel 32 in the upper elimination chamber 30 undergoes a spiral upward motion around the axis. The principle behind this is to continuously change the direction of the water flow, which greatly increases the turbulence and accelerates the elimination of ice crystals, effectively improving the ice crystal removal effect. Compared to existing technologies that only increase pipe length, this significantly enhances the turbulence (which is not achieved by the monotonous flow direction in existing technologies), thus facilitating ice crystal removal.

[0034] Preferably, the ice crystal eliminator further includes a first vortex generator 41 that can rotate freely, the first vortex generator 41 being installed within the spiral flow channel 32. Figure 2 and Figure 3 As shown, there are multiple first vortex generators 41, distributed in various sections of the spiral flow channel 32. The first vortex generator 41 can rotate freely by 720° (360° around itself and 360° around the fixed structure). The working principle of the first vortex generator 41 is to generate a large number of vortices, further increase the turbulence intensity of the water flow, and greatly improve the elimination effect and elimination speed of micro ice crystals.

[0035] Combination Figure 2 and Figure 3As shown, the ice crystal eliminator also includes a first fixing rod 42, which passes through the spiral partition structure 31 along the axial direction of the spiral flow channel 32. The first fixing rod 42 forms multiple mounting sections in the spiral flow channel 32, and the first vortex generator 41 is rotatably connected to the mounting sections. The first vortex generator 41 can rotate on its own and can rotate circumferentially around the mounting section.

[0036] exist Figure 2 In this design, a first fixing rod 42 is installed from top to bottom and passes through the spiral partition structure 31. Multiple regions of the spiral flow channel have mounting sections, each a round rod. A first vortex generator is rotatably connected to one of these mounting sections and can rotate 360° around it. Simultaneously, the first vortex generator can also rotate 360° around its own axis, allowing for free rotation. Multiple first fixing rods 42 and multiple first vortex generators are used, with each first vortex generator corresponding to a mounting section. The function of the first fixing rod 42 is to fix the relative position of the first vortex generator 41 on the spiral flow channel, making the structure more stable and preventing damage from water flow. The first fixing rod 42 also makes full use of the internal structural space of the shell. The fixed connection between the first fixing rod 42 and the spiral partition structure 31 makes the structure more compact and stable.

[0037] Preferably, the preheating hot water pipe 12 passes through both the elimination chamber 30 and the mixing chamber 20, with the port of the preheating hot water pipe 12 located within the mixing chamber 20; The spiral partition structure 31 is a spiral partition plate. The spiral partition structure 31 is sleeved and fixedly connected to the outer peripheral surface of the preheating hot water pipe 12. The spiral partition structure 31, the outer peripheral surface of the preheating hot water pipe 12 and the inner wall surface of the elimination cavity 30 together form the spiral flow channel 32.

[0038] The axis of the spiral partition structure is collinear with the axis of the preheating hot water pipe, and the baffle is simultaneously fitted onto the preheating hot water pipe. The axis of the baffle assembly formed by the baffle is collinear with the axis of the preheating hot water pipe.

[0039] The structural fit between the spiral partition structure 31 and the preheating water pipe 12 makes the overall structure more compact and stronger, making it less prone to damage from impacts. Furthermore, although the water temperature inside the preheating water pipe 12 is not high, it can still conduct heat to the spiral flow channel to a certain extent, melting the ice crystals in the mixed water and thus aiding in ice crystal removal, further enhancing the ice crystal removal effect.

[0040] The water flow process and technical principle of Example 1 are as follows (described according to the direction shown in the figure, but the structure of the example is not limited to the direction): The cold water (0℃) separated from the ice storage tank is divided into two streams, which enter the preheater and the ice crystal eliminator respectively. The cold water (0℃) entering the preheater becomes preheated water (0.5℃) through heat exchange with the refrigerant. It then moves downwards from the top of the preheated water pipe 12 and enters the inner chamber 20a from the bottom outlet. The preheated water flows left and right along the baffle channel, moving upwards. Simultaneously, the cold water (0℃) entering from the cold water pipe 11 fills the outer chamber 20b, passes through the connecting hole 23 into the inner chamber 20a, and collides and mixes with the moving preheated water (0.5℃), ultimately forming mixed water (0.3℃). This mixed water enters the baffle channel and then flows into the spiral channel in the upper eliminator chamber. During this process, the intense collision and thorough mixing of the preheated water (0.5℃) and cold water (0℃) greatly accelerates the elimination speed and effectiveness of tiny ice crystals in the water flow. The mixed water (0.3℃) entering the spiral flow channel moves upwards in a spiral motion around the preheated water pipe, which greatly increases the turbulence of the water flow. Simultaneously, multiple freely rotating vortex generators are installed in the spiral flow channel, generating numerous vortices, further increasing the turbulence intensity and significantly improving the removal effect and speed of micro-ice crystals. The mixed water (0.3℃) after micro-ice crystal removal then passes through a filtration device and enters the subcooler to participate in the next cycle.

[0041] Example 2 See Figure 5 As shown in Embodiment 2 of the present invention, an ice crystal eliminator is provided. The ice crystal eliminator includes a housing 10, a cold water pipe 11, a preheating water pipe 12, and a water outlet pipe 13. The housing 10 has a mixing chamber 20. The cold water pipe 11 is connected to the mixing chamber 20, and the cold water pipe 11 introduces cold water containing ice crystals into the mixing chamber 20. The preheating water pipe 12 is connected to the mixing chamber 20, and the preheating water pipe 12 introduces preheated water into the mixing chamber 20. The preheated water and the cold water containing ice crystals collide and mix in the mixing chamber 20. The water outlet pipe 13 is connected to the mixing chamber 20, and the water outlet pipe 13 discharges the mixed water in the mixing chamber 20.

[0042] The housing 10 has an elimination cavity 30, which is adjacent to and communicates with the mixing cavity 20. The ice crystal eliminator also includes a baffle 51, which is rotatably disposed within the eliminator cavity 30.

[0043] The turbulence-inducing component 51 generates vortices within the elimination chamber 30 and collides with ice crystals in the mixed water. This increases the turbulence of the water flow, changes its speed and direction, and enhances the ice crystal elimination effect. Furthermore, it directly collides with the ice crystals, accelerating their elimination. The turbulence-inducing component 51 has a multi-functional technical advantage, maintaining extremely low or even trace amounts of ice crystals in the mixed water flowing out of the outlet pipe, and even eliminating all ice crystals.

[0044] Preferably, the preheating hot water pipe 12 is simultaneously installed in the elimination chamber 30 and the mixing chamber 20, with the port of the preheating hot water pipe 12 located in the mixing chamber 20; the turbulence-disrupting element 51 is connected to the outer circumferential surface of the preheating hot water pipe 12 via a rotating shaft.

[0045] The structural fit between the baffle and the preheating water pipe, as well as the positional relationship of the preheating water pipe, creates a tight fit among the multiple structures of the ice crystal eliminator. The structure is compact and stable, and the baffle makes full use of the structural space, eliminating the need for other structures for fixation and saving costs.

[0046] To further stabilize the structure and further eliminate ice crystals, the ice crystal eliminator in Embodiment 2 also includes a second fixing rod 52 and a second vortex generator 53. The second fixing rod 52 is fixedly connected inside the elimination cavity 30. The second vortex generator 53 is rotatably mounted on the second fixing rod 52, and the second vortex generator 53 is staggered from the turbulence-disrupting element 51.

[0047] The second vortex generator 53 can rotate freely at 720° (360° on its own and 360° around the fixed structure). The working principle of the second vortex generator 53 is to generate a large number of vortices, further increase the turbulence intensity of the water flow, and greatly improve the elimination effect and elimination speed of tiny ice crystals.

[0048] The function of the second fixing rod 52 is to fix the relative position of the second vortex generator 53 within the elimination chamber, making the structure of the second vortex generator more stable and preventing it from being damaged by water flow. The second fixing rod 52 also makes full use of the internal structural space of the shell, making the overall structure more compact and stable.

[0049] Example 3 See Figure 6 As shown in Embodiment 3 of the present invention, a subcooled water ice-making system is provided, including the ice crystal eliminator of the above embodiment.

[0050] Preferably, the subcooled water ice-making system includes an ice storage tank 61, a preheater 62, an ice crystal eliminator 63, a filter 64, a subcooler 65, and a subcooling relief device 66, which are connected in sequence by pipelines. The cold water pipe 11 of the ice crystal eliminator is connected to the ice storage tank 61 via a bypass branch; The preheating water pipe 12 of the ice crystal eliminator is connected to the pipe of the preheater 62; The outlet pipe 13 of the ice crystal eliminator is connected to the filter device 64.

[0051] The cold water (0°C) separated from the ice storage tank 61 is divided into two streams, which enter the preheater 62 and the ice crystal eliminator 63 respectively. The cold water (0°C) entering the preheater 62 becomes preheated water (0.5°C) through heat exchange with the refrigerant, and then enters the ice crystal eliminator 63 through the preheated water pipe 12. At the same time, the cold water (0°C) from the ice storage tank 61 directly enters the ice crystal eliminator 63, where it collides and mixes with the moving preheated water (0.5°C), eventually forming mixed water (0.3°C). The mixed water (0.3°C) after the removal of tiny ice crystals passes through the filter device 64 and enters the subcooler 65 to participate in the next cycle.

[0052] Compared to existing technologies that rely solely on a preheater to heat cold water (0°C), the subcooled water ice-making system of this embodiment exhibits superior ice crystal removal efficiency and faster speed. Furthermore, the subcooled water ice-making system achieves outstanding results without requiring a high level of preheated water (existing technologies use 2°C preheated water, while this invention only uses 0.5°C). Utilizing structural advantages and water flow characteristics, it significantly saves energy. The technical solution of this invention makes the ice-making system more energy-efficient and improves the energy efficiency of the subcooled water ice-making system.
