Description

Technical Field

[0001] The utility model belongs to the technical field of cold storage equipment, and in particular relates to a movable hydrate cold storage vehicle. Background Art

[0002] Cold storage technology is an important means to improve energy efficiency and reduce economic losses. Compared with the low density of water cold storage, the low operating temperature of ice cold storage, and the easy aging of eutectic salt cold storage devices, hydrate cold storage technology has advantages because of its non-corrosiveness, suitable phase change temperature range and high phase change latent heat. Gas hydrate is an ice-like inclusion compound, which is composed of host water and guest molecules. Water molecules are combined into a cage structure through hydrogen bonds. The guest molecules occupy the gaps in the cage structure and are stabilized by van der Waals forces. Under standard conditions, the decomposition of 1 cubic meter of hydrate can produce about 0.8 cubic meters of pure water and 180 cubic meters of gas. Therefore, hydrate technology has broad application prospects in the fields of gas separation and gas storage and transportation, seawater desalination, carbon dioxide capture and cold storage.

[0003] In order to solve the problems of difficulty in hydrate formation, low conversion rate and insufficient economy in the prior art. The applicant proposed a Chinese utility model patent with application number CN202310965963.4, which discloses a hydrate cold storage system, involving the field of energy storage air conditioning technology, including a cold storage tank, a crystal promoting device, a heat exchanger, a refrigeration device and an energy release device; a crystal promoting device connected to the side of the cold storage tank is provided, and the cold storage tank is filled with cold storage medium; the present invention uses a gas circulation pump to suck gas from the upper space of the cold storage tank, and blows it into the aeration pipe at the bottom of the cold storage tank to achieve disturbance, thereby increasing the probability of nucleation and shortening the nucleation time. Compared with the method of using conventional gas cylinders to supply gas under laboratory conditions, it is more economical. However, in the above-mentioned cold storage system, since the cold storage tank and other equipment are too large, sufficient space is usually required for their installation. However, for some occasions with small space, it is impossible to install cold storage equipment, or in some scenarios where there is peak cooling, the cooling power of the equipment is insufficient (such as shopping malls, scenic spots, office buildings, etc. at extremely high temperatures), and the cooling effect cannot be met. Therefore, a mobile hydrate cold storage vehicle is urgently needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As shown in the figure, a movable hydrate cold storage vehicle includes a frame 1, a cold storage tank body 2 is arranged above the frame 1, and a heat exchanger group is arranged inside the cold storage tank body 2, wherein the heat exchanger group includes a plurality of heat exchangers 10 connected in series in sequence. In this example, there are three heat exchangers 10, and the heat exchanger 10 includes a plurality of heat exchange tubes arranged in a vertical direction, and the outside of the heat exchange tubes has uniformly arranged fins, and the fin pitch is 1.5-50mm, which is mainly used for heat conduction.

[0024] A cold storage medium is filled outside the heat exchanger 10 and inside the cold storage tank 2, wherein the cold storage medium can be a liquid cold storage medium, such as TBAB solution or TBAB+R141b; or the cold storage medium is a gaseous cold storage medium, such as R134a, and both can achieve a cold storage effect when used. In addition, in order to increase the nucleation probability of the cold storage medium, an aeration pipe can be set at the bottom of the cold storage tank 2, and a gas circulation pipeline can be installed above the cold storage tank 2. The pump body is used as a power source to blow the air in the upper space into the aeration pipe, thereby achieving a disturbance effect of the cold storage medium, shortening the nucleation time and strengthening the generation. This part of the structure and principle belongs to the conventional means in the prior art and will not be elaborated here.

[0025] The heat exchanger group is connected to three sets of inlet and outlet pipes connected in parallel, and the three sets of inlet and outlet pipes are respectively located on both sides and the tail end of the cold storage tank 2. Figure 4-5 As shown, it specifically includes a first inlet pipe 11 and a first outlet pipe 12 located at the tail end, and includes a second inlet pipe 13, a second outlet pipe 14, a third inlet pipe 15 and a third outlet pipe 16 located on both sides. The three inlet pipes are connected in parallel to each other, and the three outlet pipes are connected in parallel to each other, and a valve is installed on each pipe. When storing or releasing cold, one group of inlet and outlet pipes can be selected according to site requirements to improve efficiency. In this way, it can be connected to the refrigeration unit of the cold storage base station at night and connected to the cold taking equipment during the day, so as to achieve the purpose of storing cold at night and releasing cold during the day, thereby solving the problem of being unable to take cold due to geographical restrictions and being unable to install cold storage equipment.

[0026] By storing cold in the cold storage tank 2 at the cold storage base station at night and moving the cold storage vehicle to the target scene to take out cold during the day through the frame 1, the effect of mobile cold storage is achieved; a base 3 is connected to the bottom of the cold storage tank 2, and the base 3 can be connected to the cold storage tank 2 by welding, or fixed to the tank by bolting, and a loading assembly is provided on the base 3 for facilitating the loading or removal of the cold storage tank 2 into or out of the frame 1, specifically, the loading assembly includes a support leg 8 rotatably installed at a position below the base 3, wherein the upper end of the support leg 8 is connected to the bottom of the base 3 by a pin shaft 6, and a through hole is opened at the bottom of the base 3, and the support leg 8 is provided with a circular hole corresponding to the through hole in the vertical state, and the through hole and the circular hole are connected to each other. A limit shaft 7 can be installed at the hole to limit the rotation of the support leg 8. A moving wheel 9 is installed at the end of the support leg 8. A guide rail 102 that matches the moving wheel 9 is fixed on the surface of the frame 1. When the cold storage tank body 2 is loaded into the frame 1, the moving wheel 9 can be used to move the cold storage tank body 2 to the rear of the frame 1, and the support legs 8 can be rotated successively to make the support legs 8 contact the guide rail 102, so that the moving wheel 9 on the frame 1 and the moving wheel 9 on the ground are both supported. The cross-section of the guide rail 102 is an L-shaped structure. The L-shaped guide rail 102 can play a guiding role, so that the moving wheel 9 is located on the inner side of the guide rail 102, so that the cold storage tank body 2 can be in the middle position of the frame 1 after being moved into place.

[0027] The loading assembly also includes a positioning screw 5 installed on the base 3. When the support leg 8 is folded, rotating the positioning screw 5 can make the positioning screw 5 abut against the side position of the support leg 8. The purpose of this arrangement is to use the positioning screw 5 to effectively support the support leg 8. When the cold storage tank body 2 has not been fully loaded onto the frame 1, the moving wheel 9 can continue to contact the guide rail 102, thereby supporting the cold storage tank body 2. When the cold storage tank body 2 is fully loaded onto the frame 1, the positioning screw 5 can be rotated in the opposite direction to disengage the positioning screw 5 from the support leg 8, and the cold storage tank body 2 can be placed above the frame 1 under the action of its own gravity.

[0028] More specifically, the loading assembly also includes a limit plate 4 installed below the front and rear ends of the base 3, and a limit groove 101 matching the limit plate 4 is provided at the front and rear positions of the upper surface of the frame 1. The limit plate 4 can be inserted into the limit groove 101. This arrangement is mainly to prevent the base 3 and the cold storage tank body 2 from shifting during the movement of the frame 1.

[0029] This movable hydrate cold storage vehicle can move the cold storage tank 2 to a designated position driven by the vehicle frame 1, so as to achieve a cooling effect in places where the space is limited and cold storage equipment cannot be installed. It has the advantages of flexible mobility, convenient operation and wide application range.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
