Fig. 3 is a schematic structural diagram of a solid phase regenerator according to another embodiment of the present invention. As shown in fig. 3, in an embodiment of the present invention, the porous flow guide 3 is an arc structure, the arc structure protrudes toward a direction away from the air inlet pipeline 2, and the arc structure is located on an inner wall of the solid phase regenerator tank 1 connected to the inlet. The cambered surface structure can guide the airflow entering the solid phase regenerator tank body 1 through the air inlet pipeline 2 towards a plurality of directions.
When low-temperature airflow enters the porous flow guider 3 from the air inlet pipeline 2, the low-temperature airflow enters the solid phase regenerator tank body 1 through the small holes on the cambered surface structure of the porous flow guider 3, the low-temperature airflow at the inlet is changed into multi-directional and fine-bundle-shaped dispersed low-temperature airflow from single radial strand-shaped distribution, and then the low-temperature airflow is distributed more uniformly in the solid phase regenerator tank body 1. The porous fluid director 3 plays a role of uniformly distributing low-temperature air flow.
Specifically, in an embodiment of the present invention, the porous flow guiding device 3 is formed by rolling a stainless steel porous screen plate, and the porous flow guiding device 3 may also be made of other low temperature resistant materials such as aluminum alloy, and is not limited to the materials described in the embodiment of the present invention.

With continued reference to fig. 1, the porous sealing cover 4 is disposed in the solid phase regenerator tank 1 and above the porous flow guider 3, and the surface of the porous sealing cover 4 protrudes in a direction away from the porous flow guider 3, and the concave surface faces the direction of the air inlet pipeline. The periphery of the porous sealing cover 4 is connected with the inner wall of the solid phase regenerator tank body 1, the porous sealing cover 4 divides the solid phase regenerator tank body 1 into an upper part and a lower part, wherein the porous fluid director 3 is positioned in the lower part, the air inlet pipeline 2 is connected with the lower part, and the solid phase regenerator material 5 is positioned in the upper part. The diameter of the porous sealing cover 4 is increased along with the increase of the diameter of the solid phase regenerator tank body 1, so that the diameter of the porous sealing cover 4 is always matched with the inner diameter of the solid phase regenerator tank body 1, and the effect of supporting the solid phase regenerator material 5 is achieved.
In addition, the surface of the porous sealing cover 4 is provided with small holes of 5-8mm, the small holes can be in any shape such as round, square or strip shape, and the pore diameters of the small holes at different positions on the surface of the porous sealing cover can be the same or different. Since the pore diameter of the surface of the porous cover 4 is smaller than the equivalent diameter of the solid phase cold storage material 5, the solid phase cold storage material 5 does not leak out of the pores of the porous cover 4. Meanwhile, the porous sealing cover 4 and the porous fluid director 3 form a cavity together, and the cavity can be used as a mixing space after low-temperature airflow enters and can further uniformly distribute the low-temperature airflow.
Specifically, the porous flow director 3 is now exemplified as a cone structure: when low-temperature air flow enters a cavity formed by the porous fluid director 3 and the porous sealing cover 4 through the small holes on the side wall and the bottom surface of the porous fluid director 3, the low-temperature air flow is mixed in the cavity and then enters the solid phase cold storage material 5 through the small holes on the surface of the porous sealing cover 4. Because the surface of the porous sealing cover 4 protrudes to the direction away from the porous fluid director 3, the low-temperature airflow passing through the porous sealing cover 4 is multi-directional and fine-bundle dispersed low-temperature airflow, and the uniform distribution of the low-temperature airflow entering the solid phase cold storage material 5 is realized.
In an embodiment of the present invention, the material of the porous sealing cover 4 is stainless steel, or other low temperature resistant materials such as aluminum alloy, etc., which has high strength under low temperature conditions, and can support the heavy solid phase cold storage material 5 with a thinner thickness, thereby saving the manufacturing cost, and any material having such characteristics is within the protection scope of the present invention, and is not limited to the material described in the embodiment of the present invention.
In an embodiment of the present invention, the periphery of the porous sealing cover 4 is welded on the inner wall of the solid phase regenerator tank 1, and the periphery of the porous sealing cover 4 may also be connected with the inner wall of the solid phase regenerator tank 1 by other methods, not limited to the connection method described in the embodiment of the present invention.
In one embodiment of the invention, the porous closure 4 is any one of disc-shaped, oval-shaped, or spherical-crown shaped.
With continued reference to fig. 1, a solid phase regenerator material 5 is filled within the solid phase regenerator tank 1 above the porous cover 4. Specifically, in one embodiment of the present invention, the solid phase cold storage material 5 may be a mixture of one or more of metal, rock, ore, and concrete. The solid phase cold storage material 5 can be spherical or square, and the equivalent diameter of the solid phase cold storage material is larger than the diameter of the small hole on the surface of the porous sealing cover 4, so that the solid phase cold storage material 5 is prevented from falling into the air inlet pipeline 2 through the small hole on the porous sealing cover 4. In one embodiment of the invention the optional solid phase cold storage material 5 has an equivalent diameter of 10-20 mm.
Specifically, after passing through the small holes on the surface of the porous sealing cover 4, the low-temperature airflow is uniformly sprayed to the periphery, then enters the gap flow channel formed by the solid-phase cold storage material 5, and sufficiently exchanges heat with the solid-phase cold storage material 5, so that the temperature of the solid-phase cold storage material 5 is homogenized on the same section, and the formation of flowing and temperature dead zones is avoided.
Continuing to refer to fig. 1, the exhaust pipeline 6 is connected with the outlet of the solid phase regenerator tank 1, the nominal diameter of the exhaust pipeline 6 increases along with the increase of the outlet diameter of the solid phase regenerator tank 1, so as to ensure that the diameter of the exhaust pipeline 6 is always matched with the outlet diameter of the solid phase regenerator tank 1, and the exhaust pipeline is used for exhausting the air flow which exchanges heat with the solid phase regenerator material 5 from the solid phase regenerator tank 1.
According to the solid-phase regenerator provided by the embodiment of the invention, the porous flow guider is designed, so that the uniform distribution and mixing of low-temperature air flow at the inlet of the solid-phase regenerator are realized, the temperature of the same section in the solid-phase regenerator is uniform, the efficiency of the regenerator is improved, and the energy storage efficiency of liquid air is further improved.
The working principle of the solid phase regenerator device will be described in detail below with reference to fig. 1 as an example:
when the cold accumulation process is started, the low-temperature airflow flows into the solid phase cold accumulator tank body 1 from the bottom of the solid phase cold accumulator tank body 1 through the air inlet pipeline 2. Firstly, low-temperature air flow passes through the porous fluid director 3 and is sprayed out from small holes on the side wall and the bottom surface of the porous fluid director 3, and the low-temperature air flow respectively flows to the middle and the periphery of the solid phase regenerator tank body 1. Meanwhile, the low-temperature air flow flows to the porous sealing cover 4 after being further uniformly mixed in a cavity formed by the porous fluid director 3 and the porous sealing cover 4, and is uniformly sprayed to the periphery from small holes on the surface of the porous sealing cover 4. Then, the low-temperature air flow enters a gap flow channel formed by the solid phase cold accumulation material 5, and fully exchanges heat with the solid phase cold accumulation material 5, so that the temperature of the solid phase cold accumulation material 5 is homogenized on the same section, the formation of flowing and temperature dead zones is avoided, and finally, the air flow after heat exchange is discharged from the exhaust pipeline 6.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
