Thermocline storage tank structure with middle partition plate

Abstract

The invention relates to a thermocline storage tank structure with a middle partition plate, solves the problem that the invalid space of an existing thermocline storage tank is large in proportion, and belongs to the technical field of thermocline storage tanks. The thermocline storage tank structure comprises a thermocline storage tank structure body and the middle partition plate, wherein the middle partition plate is arranged in the thermocline storage tank structure body, and divides the space of the thermocline storage tank structure body into an upper portion and a lower portion; the middle partition plate is not fixedly connected with the thermocline storage tank structure body; and a gap is formed between the middle partition plate and the thermocline storage tank structure body.The thermocline storage tank structure further comprises a main controller, electromagnets and balancing weights, wherein the multiple electromagnets are fixed on the lower surface of the middle partition plate; the electromagnets are uniformly distributed on the lower surface of the middle partition plate; the balancing weights of which the number is equal to that of the electromagnets are arranged at the bottom of the thermocline storage tank structure body; the balancing weights are positioned under the electromagnets, and are in one-to-one correspondence with the electromagnets; and electromagnetic control signals of the main controller are separately transmitted to the electromagnets, and are used for controlling whether the electromagnets attract the balancing weights under the electromagnets or not.

Description

technical field [0001] The invention relates to a thermocline storage tank structure with an intermediate partition plate, belonging to the technical field of thermocline storage tanks. Background technique [0002] The thermocline heat storage technology enables the same heat storage device to hold both hot and cold media at the same time, which greatly simplifies the configuration and cost of the energy storage system, and is a key technology to achieve low-cost energy storage. However, due to the existence of the thermocline layer, there is space that cannot be effectively used in the storage tank. The larger the storage tank, the greater the absolute value of the invalid space; the smaller the storage tank, the greater the proportion of the invalid space. Whether it is a large thermocline storage tank or a small thermocline storage tank, the existence of dead space greatly affects the cost and efficiency of the thermocline energy storage system. [0003] The height redu...
