Description

Container lining storage tank for flow battery

Technical Field

The utility model belongs to the technical field of all-vanadium redox flow battery equipment, and particularly relates to a container lining storage tank for a redox flow battery.

Background

Current flow battery systems can be divided into two product forms, one for relatively small capacity battery systems, with individual system units below 500kWh, typically using container-type energy storage products. One is for relatively large capacity battery systems, with individual system units above 500kWh, typically using stationary energy storage products. The container type energy storage system generally uses a square storage tank because of the limitation of the space and shape in the container; because the electrolyte capacity of the fixed energy storage system is large, the container cannot meet all loads (other equipment such as a pile, a pump, a heat exchanger, an electrical cabinet body and the like are required to be arranged in the container besides the electrolyte), and only the storage tank can be arranged externally, so that the required electrolyte can be contained by using the cylindrical storage tank.

The cylindrical storage tank has the advantages of large capacity, flexible size adjustment, inconvenient transportation and installation, large occupied space for indoor use, poor outdoor use strength and durability, poor heat preservation capability in high-temperature extremely cold areas, poor beautiful modular arrangement of items and the like. The square storage tank needs the container to bear, has the installation fixed inconvenient, needs to have certain wall thickness and strengthening rib, extravagant container inner space, and maintenance space and installation space need be left to all interfaces of storage tank, and whole space utilization is low in the container.

Disclosure of Invention

The utility model aims to provide a container lining storage tank for a flow battery so as to solve the technical problems.

The utility model aims to solve the technical problems, and is realized by adopting the following technical scheme:

the container lining storage tank for the flow battery is characterized in that the container lining storage tank is square in the outside, glass fiber reinforced plastic linings are arranged on the inner walls of a bottom plate, a side plate, a top plate and an end plate of the container, a liquid inlet is formed in the upper portion of one side end plate and the upper portion of the glass fiber reinforced plastic lining on the inner side of the one side end plate, a liquid outlet is formed in the lower portion of the one side end plate, and flanges are arranged on the liquid inlet and the liquid outlet.

Preferably, a plurality of reinforcing ribs are uniformly and fixedly arranged on the outer side walls of the bottom plate, the side plates and the end plates of the container.

Preferably, the thickness of the glass fiber reinforced plastic lining is less than or equal to 8mm.

The beneficial effects of the utility model are as follows:

1. according to the utility model, the container body is used as a template of the glass fiber reinforced plastic storage tank, so that the thickness of the glass fiber reinforced plastic storage tank plate is reduced, and the material cost is reduced;

2. according to the utility model, the glass fiber reinforced plastic storage tank is lined into a standard container, and the problems of heat preservation, transportation and the like of electrolyte are effectively solved by adopting the mature schemes of heat preservation, transportation and the like of the container;

3. according to the utility model, the glass fiber reinforced plastic storage tank is lined into the standard container, the capacity unit and the flow battery system unit are mutually independent, and the flow and standardization are realized in production and transportation, so that the industrial pain point of mutual elbow pulling of the capacity unit and the system unit in the large-scale energy storage system is solved.
