Description

Technical Field

[0001] This utility model relates to a high-efficiency ice slurry energy storage device suitable for both hot and cold operating conditions, belonging to the technical field of cold storage equipment. Background Technology

[0002] Ice slurry storage tanks are an important component of cold storage systems, primarily used for storing and releasing cold energy. They achieve efficient energy storage and regulation through the heat exchange of ice slurry (a mixture of ice and water). Ice-making technology can be divided into static ice-making and dynamic ice-making. Compared to static ice-making, dynamic ice-making can continuously produce ice slurry fluid with excellent flow heat exchange properties, which can be directly used as an energy storage medium or intermediate medium for transportation.

[0003] During the ice storage and melting process, the ice slurry and water flow are usually transported through a single pipeline. This can easily lead to uneven melting of the ice slurry during the internal cold storage circulation, resulting in a decrease in the overall efficiency of the device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-efficiency ice slurry energy storage device suitable for both hot and cold working conditions, which solves the problem of uneven dissolution of ice slurry inside the cold storage tank in the prior art.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a high-efficiency ice slurry energy storage device suitable for both hot and cold operating conditions, comprising:

[0006] The tank body, serving as a container for cold and hot energy storage, has an ice slurry conveying assembly installed in its upper part; a supporting column is located inside the tank body, and an upper water inlet pipe and a lower water inlet pipe are installed on the supporting column; an upper water distributor is located at the upper end of the supporting column; and a lower water distributor is located at the lower end of the supporting column; wherein, the supporting column is hollow inside and includes an upper pipe and a lower pipe that are not connected to each other, the upper water inlet pipe is connected to the upper water distributor through the upper pipe, and the lower water inlet pipe is connected to the lower water distributor through the lower pipe.

[0007] By adopting the above technical solution, supporting columns are installed inside the tank, and upper and lower water distributors are installed respectively to assist in achieving hot and cold circulation. During ice melting, the ice slurry inside the tank can be dissolved evenly, and during ice storage, the ice slurry can be evenly added into the tank, improving circulation efficiency. The columns also provide support for the entire tank, improving its overall structural strength.

[0008] The present invention is further configured such that: the upper water distributor includes an upper connecting shell, and a plurality of primary water distribution pipes are equidistantly arranged in the circumferential direction on the upper connecting shell; secondary water distribution pipes are arranged on the primary water distribution pipes; and a plurality of drain outlets are arranged on the secondary water distribution pipes.

[0009] By adopting the above technical solution, it is possible to ensure that the pressure is balanced when the fluid radiates and diffuses from the center to the surroundings, avoid local flow concentration, and use multi-stage diversion to achieve step-by-step pressure reduction and discharge, which can effectively reduce turbulence and energy loss in the pipe.

[0010] The present invention is further configured such that: a flow equalization component is installed on the drain outlet, the flow equalization component includes a connecting part connected to the drain outlet, a bowl-shaped guide plate with an upward opening is provided above the connecting part, and a flow-blocking plate is installed above the guide plate.

[0011] By adopting the above technical solution, the uniformity of drainage of the upper water distributor can be further improved. When the water flows out through the flow equalization component, it is first blocked by the flow baffle and then spreads to the surroundings. After it is filled in the flow guide plate, it overflows to the surroundings, which can prevent the water from directly impacting the top of the tank due to excessive water pressure.

[0012] The present invention is further configured such that: a flow equalization plate is installed in the tank above the lower water distributor, and a plurality of through holes are evenly distributed on the flow equalization plate.

[0013] By adopting the above technical solution, the inner cavity of the entire tank is divided into upper and lower parts. The ice slurry is stored in the tank above the flow equalization plate, preventing the ice slurry from sinking to the bottom of the tank and clogging the drain outlet. During ice melting, the low-temperature water from the melted ice slurry above the flow equalization plate flows into the lower part of the tank through the through holes on the flow equalization plate. Because the through holes on the flow equalization plate are evenly distributed, the low-temperature water can flow evenly from the flow equalization plate to the tank below the flow equalization plate.

[0014] The present invention is further configured such that: the lower water distributor includes a lower connecting shell, and a plurality of bottom water pipes are equidistantly arranged in the circumferential direction on the lower connecting shell.

[0015] By adopting the above technical solution, the uniformity of drainage from the lower water distributor can be improved, and the hot and cold circulation can be promoted.

[0016] The present invention is further configured such that: the ice slurry conveying assembly includes a main pipe, one end of which is connected to an ice slurry supply module, and the other end passes through the tank wall and enters the tank interior.

[0017] By adopting the above technical solution, ice slurry can be stably and evenly introduced into the tank.

[0018] The present invention is further configured such that: the ice slurry conveying assembly further includes a primary branch pipe connected to the main pipeline, a secondary branch pipe is connected to the primary branch pipe, and a tertiary branch pipe is connected to the secondary branch pipe.

[0019] By adopting the above technical solution, multi-stage diversion can be achieved, forming multiple ice slurry discharge outlets, which can reduce the discharge pressure of ice slurry and improve the uniformity of ice slurry laying.

[0020] The present invention is further configured such that: the three-stage diversion pipe has a U-shaped structure, the middle part of the three-stage diversion pipe is connected to the two-stage diversion pipe, and both ends are open, with the openings facing the lower part of the tank.

[0021] By adopting the above technical solution, the ice slurry can be effectively guided.

[0022] The present invention is further provided with a drain pipe at the bottom of the tank.

[0023] By adopting the above technical solutions, drainage and heating / cooling cycle efficiency can be improved.

[0024] The beneficial effects of this utility model are:

[0025] By installing support columns and upper and lower water distributors inside the tank, the ice melting efficiency of the device can be effectively improved. The upper and lower water distributors are arranged in a multi-stage diversion manner to form multiple drainage outlets, which can increase the drainage area of ​​the two water distributors, thereby increasing the contact area between the water flow and the ice slurry during the hot and cold cycle and improving the circulation efficiency.

[0026] By deploying the ice slurry delivery components in a multi-stage distribution pattern, the ice slurry is discharged through multiple outlets, ensuring that the ice slurry is evenly distributed within the tank during ice storage without localized accumulation, thus improving the efficiency of subsequent ice melting.

[0033] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0034] like Figure 1 As shown, a high-efficiency ice slurry energy storage device suitable for both hot and cold operating conditions includes a tank 1, a supporting column 3, an upper water distributor 6, a lower water distributor 7, and an ice slurry conveying assembly 2.

[0035] Tank 1 serves as a container for thermal energy storage. A supporting column 3 is positioned in the middle of tank 1, its lower end fixed to the bottom surface and its upper end fitting against the top of tank 1, providing some support for the top cover. A drain pipe 9 is installed at the bottom of tank 1 for drainage. The interior of the supporting column 3 is hollow and consists of two non-interconnected pipes, an upper pipe 301 and a lower pipe 302. An upper water distributor 6 is fixed to the upper end of the supporting column 3 and communicates with the interior of the upper pipe 301, while a lower water distributor 7 is fixed to the lower end of the supporting column 3 and communicates with the interior of the lower pipe 302. The upper water distributor 6 sprays hot water into tank 1 during ice melting, while the lower water distributor 7 replenishes water into tank 1 before ice storage and also drains cold water from the bottom of tank 1 into the refrigeration pipes during ice melting. An ice slurry conveying assembly 2, used to convey ice slurry into tank 1, is suspended and fixed below the upper water distributor 6.

[0036] When ice is stored inside tank 1, ice slurry is transported into tank 1 via ice slurry conveying assembly 2 to store cold energy. When melting ice, hot water is sprayed into tank 1 via upper water distributor 6 to melt the ice slurry and release cold energy. By installing support columns 3 inside tank 1, and installing upper water distributor 6 and lower water distributor 7 respectively to assist in achieving hot and cold circulation, the ice slurry inside tank 1 can be evenly dissolved during ice melting, and the ice slurry can be evenly added into tank 1 during ice storage, improving circulation efficiency. The columns also support the entire tank 1, improving its overall structural strength.

[0037] Furthermore, a flow equalization plate 8 is installed inside the tank 1 above the lower water distributor 7, and several through holes are evenly distributed on the flow equalization plate 8.

[0038] The flow equalization plate 8 divides the inner cavity of the entire tank 1 into upper and lower parts. The ice slurry is stored in the tank 1 above the flow equalization plate 8, preventing the ice slurry from sinking to the bottom of the tank 1 and clogging the drain outlet. During ice melting, the low-temperature water from the melted ice slurry above the flow equalization plate 8 flows into the tank 1 below through the through holes on the flow equalization plate 8. Because the through holes on the flow equalization plate 8 are evenly distributed, the low-temperature water can flow evenly from the flow equalization plate 8 to the tank 1 below the flow equalization plate 8.

[0039] Specifically, such as Figure 2 As shown, the upper water distributor 6 includes an upper connecting shell 601, which is hollow inside and communicates with the inner cavity of the upper pipe 301. Several primary water distribution pipes 602 are equidistantly arranged in the circumferential direction on the upper connecting shell 601, and secondary water distribution pipes 603 are fixedly installed at the ends of the water distribution pipes after they extend outward. Both ends of the secondary water distribution pipes 603 are drain outlets, and the opening direction of the drain outlets faces the top of the tank 1.

[0040] Furthermore, such as Figure 3 As shown, a flow equalization component 604 is installed on the drain outlet. The flow equalization component 604 includes a connecting part 6041 connected to the drain outlet. A bowl-shaped guide plate 6042 with its opening facing upward is provided above the connecting part 6041. A flow-blocking plate 6043 is installed above the guide plate 6042.

[0041] like Figure 2 As shown, the lower water distributor 7 includes a lower connecting shell 701. The lower connecting shell 701 is hollow inside and communicates with the inner cavity of the lower pipe 302. Several bottom water pipes 702 are equidistantly arranged in the circumferential direction on the lower connecting shell 701, and the ends of the bottom water pipes 702 are set with their openings facing downwards.

[0042] like Figure 4 and Figure 5 As shown, the ice slurry conveying assembly 2 includes a main pipe 201. One end of the main pipe 201 is connected to an ice slurry supply module, which supplies ice slurry into the main pipe 201. The other end of the main pipe 201 passes through the wall of the tank 1 and enters the interior of the tank 1. A primary diversion pipe 202 is connected to the end of the main pipe 201, a secondary diversion pipe 203 is connected to the primary diversion pipe 202, and a tertiary diversion pipe 204 is connected to the secondary diversion pipe 203. Through multi-stage diversion, multiple ice slurry discharge outlets are formed, which can reduce the discharge pressure of the ice slurry and form multiple points for ice slurry discharge, thereby improving the uniformity of ice slurry laying.

[0043] Furthermore, the tertiary diversion pipe 204 has a U-shaped structure, connecting to the secondary diversion pipe 203 in the middle, with both ends open and facing downwards towards the tank 1. This facilitates the rapid discharge of ice slurry.

[0044] In another embodiment, the tank 1 can also be used as a water storage tank to store cold or hot water according to actual needs. The ice slurry conveying component 2 stops operating, and cold or hot water is introduced into the tank 1 through the upper water distributor 6 and the lower water distributor 7 to achieve circulating energy storage.

[0045] During the operation of tank 1, different energy storage media are introduced into tank 1 under different working conditions, which can realize the conversion of multiple functions such as ice storage, ice melting, water cooling, and water heating. It can meet the energy supply needs of different periods throughout the year. Ice storage and melting are carried out during the summer when the cooling demand is high, water cooling is carried out during the transitional season when the cooling demand is low, and water heating is carried out during the winter when the heating demand is high.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
