Description

Technical Field

[0001] This utility model relates to the field of cross-seasonal energy storage system technology, and in particular to a partitioned reaction device for calcium hydroxide solution in a reversible thermochemical reaction. Background Technology

[0002] Trans-seasonal thermal energy storage utilizes reversible thermochemical reactions to store and release heat, enabling long-term, lossless heat storage. It allows summer heat energy to be stored for winter use, improving heat quality and facilitating grid peak shaving. It can also be coupled with thermal power units. For example, calcium hydroxide dehydrates to form calcium oxide, simultaneously storing heat, while the reverse reaction releases heat. Calcium oxide (lime) is abundant, inexpensive, highly stable, allows for controllable heat storage and release, produces no pollutants, has an energy density several times that of molten salt, and can be used on a large scale. After years of research, the problem of low thermal energy storage efficiency has been effectively solved, and thermal energy storage materials can meet the needs of practical applications.

[0003] However, the reaction vessels for calcium hydroxide solutions are generally integrated reaction vessels. The calcium oxide accumulated in the integrated reaction vessel has a low reaction efficiency, and heat collection during the reaction process is relatively difficult. Utility Model Content

[0004] The purpose of this invention is to provide a partitioned reaction device for calcium hydroxide solution in reversible thermochemical reactions, so as to solve the problems of low reaction efficiency of calcium oxide using existing integrated reaction tanks and the difficulty of heat collection during the reaction process.

[0005] To solve the above-mentioned technical problems, this utility model provides a partitioned reaction device for calcium hydroxide solution in reversible thermochemical reactions, including multiple partitioned reaction tubes arranged in an array;

[0006] One end of the partitioned reaction tube is connected to the calcium hydroxide mixture delivery tube, thereby delivering the calcium hydroxide mixture to the partitioned reaction tube for a continuous exothermic reaction;

[0007] The other end of the partitioned reaction tube is connected to the calcium hydroxide mixture recovery tube, which is used to recover the calcium hydroxide mixture after the reaction;

[0008] The partitioned reaction tube is also provided with a cold water pipe and a hot water pipe at either end. Cold water is introduced into the partitioned reaction tube through the cold water pipe for heat exchange, and hot water is recovered and reused from the hot water pipe, forming a continuous heat exchange.

[0009] Preferably, each of the partitioned reaction tubes has a double-layer structure, with the inner cavity being the exothermic reaction zone of the calcium hydroxide mixture and the hollow cavity being the heat exchange zone; and cold water flows continuously within the heat exchange zone, absorbing heat energy to become hot water, which is then recycled and reused.

[0010] Preferably, a spiral heat exchange tube is arranged along the length direction inside the hollow cavity of each of the partitioned reaction tubes, and cold water flows spirally along the spiral heat exchange tubes, absorbing heat energy during the flow.

[0011] Preferably, the inlet and outlet of the spiral heat exchanger tube are located on the same side, and the inlet is connected to the cold water pipe, and the outlet is connected to the hot water pipe. The cold water passes through the cold water pipe, the spiral heat exchanger tube and the hot water pipe in sequence for continuous heat exchange.

[0012] Preferably, the calcium hydroxide mixture delivery pipe is connected to the multiple partitioned reaction pipes via a multi-port pipe. The main pipe of the multi-port pipe is connected to the calcium hydroxide mixture delivery pipe, and multiple branch interfaces are connected to the partitioned reaction pipes respectively. Furthermore, each branch interface is equipped with an independently controlled solenoid valve for individually controlling the on / off state of each branch interface.

[0013] Preferably, the calcium hydroxide mixture delivery pipe is also equipped with a delivery pump, which pressurizes and pumps the calcium hydroxide mixture into the partitioned reaction pipe.

[0014] Preferably, the calcium hydroxide mixture delivery pipe is also equipped with a calcium hydroxide mixture detection end, and the calcium hydroxide mixture passes through the calcium hydroxide mixture detection end before entering the partitioned reaction pipe.

[0015] Preferably, the calcium hydroxide mixture recovery pipe is connected to the multiple partitioned reaction pipes via a multi-port pipe II. The main pipe of the multi-port pipe II is connected to the calcium hydroxide mixture recovery pipe, and multiple branch interfaces are respectively connected to the partitioned reaction pipes to recover the calcium hydroxide mixture after the exothermic reaction.

[0016] Preferably, the calcium hydroxide mixture recovery pipe is also equipped with a recovery pump, which is used to recover and reuse the reacted calcium hydroxide mixture.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the delivery pump delivers the calcium hydroxide mixture to separate partitioned reaction tubes for exothermic reaction. By using multiple partitioned reaction tubes, the calcium hydroxide mixture can undergo a partitioned exothermic reaction, which is more efficient than an integrated reaction tank and allows for faster heat supply. Alternatively, some partitioned reaction tubes can be opened to output a small amount of hot water, thus avoiding waste. Attached Figure Description
