Flow battery pile with eccentric liquid inlet plate structure

Technical Field

In the current society, with the improvement of living standard, various electronic device products such as mobile phones, computers, televisions, electric automobiles and other high-end equipment are continuously developed, so that the living of vast users is greatly enriched. The development of the high-tech products has a tighter dependence on high-grade energy (mainly electric energy) and has an increasing demand.

Meanwhile, the energy sources such as coal, petroleum, natural gas and the like are gradually reduced, and the environment pollution is caused during use, so that the research and development of large-scale renewable energy sources become the first choice. Because renewable energy sources (such as wind energy, solar energy, tidal energy and the like) generate electricity with the characteristics of instability and discontinuity, a matched energy storage system is needed to balance so as to ensure continuous and stable use.

The energy storage battery is the heart of the energy storage system. Among the existing energy storage batteries, the flow battery has the advantages of good safety, high power, long service life, cleanness, environmental protection and the like, and is the best choice for realizing a large-scale energy storage scheme.

When two half-stacks adjacent liquid inlet plates adjacent to each other are tightly attached together, liquid inlet holes used for connecting external liquid inlet and outlet on the liquid inlet plates are tightly adjacent. When the external pipelines are connected, the pipeline distance is limited by the liquid inlet and outlet on two adjacent liquid inlet plates. Causing the externally connected tubing to interfere.

Detailed Description

The present utility model is described in detail below by way of specific examples, but the scope of the present utility model is not limited thereto. Unless otherwise specified, the experimental methods used in the present utility model are all conventional methods, and all experimental equipment, materials, reagents, etc. used can be obtained from commercial sources.

Example 1

Flow battery pile with eccentric liquid inlet plate structure

As shown in fig. 5-8, in a liquid inlet plate with an eccentric liquid inlet, when the positions of a liquid inlet long hole (81) and an end liquid inlet (82) of the eccentric liquid inlet plate (8) are designed, the edge of the liquid inlet long hole (81) is ensured to be positioned at the inner side of the edge of the end liquid inlet (82), a certain distance B is reserved, and the edge of the liquid inlet long hole (81) is prevented from exceeding the edge of the inner wall of the end liquid inlet (82) due to machining errors and the like. In the processing process, the middle liquid inlet long hole (81) is processed first, and then the end liquid inlet hole (82) is processed. The inner wall of the end liquid inlet hole (82) is prevented from being damaged, and the sealing performance of the joint (4) of the liquid inlet pipeline is affected. When the aperture of the end liquid inlet hole (82) of the eccentric liquid inlet plate (8) is designed, the distance C between the inner wall of the eccentric rear end liquid inlet hole (82) of the end liquid inlet hole (82) and the edge of the eccentric liquid inlet plate (8) is considered, and certain strength of the part after processing is ensured. Can not cause damage in the subsequent packaging and transportation process.

As shown in fig. 9, 10 and 11, the eccentric distance D exists between the end liquid inlet holes (82) and the center of the eccentric liquid inlet plate (8), and the end liquid inlet holes (82) on two adjacent eccentric liquid inlet plates (8) in the middle are eccentric in opposite directions, so that the distance E between the adjacent end liquid inlet holes (82) is increased. The liquid inlet pipeline joint (4) connected with the middle liquid inlet plate is ensured to have enough space, and the liquid inlet pipeline joint is not mutually interfered during installation, so that the position requirement of the installation design of the liquid inlet pipeline (7) is met.

Taking a Battery40 flow Battery stack as an example, as shown in fig. 9, a liquid inlet plate of the flow Battery stack is an eccentric liquid inlet plate, the eccentric distance D of a liquid inlet hole on the middle liquid inlet plate is 4mm, and the distance E between adjacent liquid inlet holes is increased by 8mm. The edge of the liquid inlet long hole of the eccentric liquid inlet plate is arranged on the inner side of the edge of the end liquid inlet hole, the distance B is 1.5mm, and the distance C between the inner wall of the end liquid inlet hole and the edge of the eccentric liquid inlet plate is 2.5mm.

After the design scheme is adopted, the sealing performance of the bonding of the end liquid inlet hole and the liquid inlet pipeline joint is good, the mechanical strength of the distance between the inner wall of the liquid inlet hole at the upper end part of the eccentric liquid inlet plate and the edge of the eccentric liquid inlet plate meets the use requirement in subsequent packaging and transportation, the liquid inlet pipeline joint connected with the middle liquid inlet plate has enough installation space, and the middle liquid inlet pipeline joints are not mutually interfered, so that the requirement of system pipeline design is met.

Comparative example 1

Flow battery pile without eccentric liquid inlet plate structure

As shown in fig. 1 and fig. 2, the flow battery pile is formed by parallel assembly of a left half pile (1) and a right half pile (2). The left half pile (1) comprises an outer liquid inlet plate (3), a liquid inlet pipeline joint (4) and an inner liquid inlet plate (5), and the inner liquid inlet plate (5) and the inner liquid inlet plate of the right half pile (2) are tightly close together to form an intermediate liquid inlet plate of the flow battery pile.

As shown in fig. 3 and 4, when the liquid inlet plate of the flow battery pile adopts the non-eccentric liquid inlet plate (6), the distance A between the liquid inlet holes on the middle liquid inlet plate is smaller. Because the installation distance is insufficient, the liquid inlet pipeline joints (4) connected with the middle liquid inlet plate (6) are mutually interfered, and the connection, the fixation and the installation of the liquid inlet pipeline (7) are difficult and the potential safety hazard is avoided.

The above-described embodiments are only preferred embodiments of the utility model, and not all embodiments of the utility model are possible. Any obvious modifications thereof, which would be apparent to those skilled in the art without departing from the principles and spirit of the present utility model, should be considered to be included within the scope of the appended claims.
