Description

Technical Field

[0001] This utility model relates to the technical field of steam heat storage, and in particular to a steam heat storage self-superheating system. Background Technology

[0002] Steam accumulators are highly efficient and energy-saving thermal devices that balance steam supply and demand fluctuations by utilizing the heat storage capacity of water, thereby reducing the burden on boilers. Existing steam accumulators, such as the vertical steam accumulator disclosed in utility model patent CN112325689B and the steam accumulator disclosed in utility model patent CN118424021B, can all achieve the balance of steam supply and demand fluctuations and reduce the burden on boilers.

[0003] However, during use, it was found that the existing steam accumulator has a relatively simple structure. During the long-distance transportation of saturated steam, the steam is prone to cooling down and it is difficult to maintain the state of saturated steam. This results in a decrease in the quality of steam at the receiving point and the generation of a large amount of condensate, leading to poor practicality. Therefore, there is an urgent need for a steam heat storage self-superheating system to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steam heat storage self-superheating system that transports saturated steam to a steam accumulator through an inlet pipe, allowing the steam accumulator to store the saturated steam. When needed, the saturated steam is discharged into the superheater through the superheater inlet pipe, where it is heated to form superheated steam. The superheated steam is then discharged through the superheater outlet pipe. This system facilitates the continuous maintenance of saturated steam during long-distance transportation, improves the steam quality at the receiving point, and reduces the generation of condensate.

[0005] This utility model discloses a steam heat storage self-superheating system, including a steam heat storage device; it also includes a steam inlet pipe, a superheater inlet pipe, a superheater, and a superheater outlet pipe. One end of the steam inlet pipe is installed on the steam heat storage device, the superheater is installed in the steam heat storage device, and the superheater is connected to the interior of the steam heat storage device through the superheater inlet pipe. One end of the superheater outlet pipe is installed on the superheater, and the other end of the superheater outlet pipe extends to the outside of the steam heat storage device.

[0006] Saturated steam is transported to a steam accumulator via an inlet pipe, where it is stored. When needed, the saturated steam is discharged from the accumulator into the superheater via the superheater inlet pipe. The superheater heats the saturated steam to form superheated steam, which is then discharged through the superheater outlet pipe. This process ensures that the steam remains saturated during long-distance transport, improves the steam quality at the receiving point, and reduces condensate production.

[0007] Preferably, the steam accumulator is internally equipped with accumulator components. The steam accumulator is provided with a steam inlet and a steam outlet. One end of the steam inlet pipe and one end of the accumulator components are both installed on the steam inlet of the steam accumulator, and one end of the superheater inlet pipe is installed on the steam outlet of the steam accumulator. Saturated steam is discharged into the accumulator components through the steam inlet pipe, and the accumulator components fully exchange heat between the saturated steam and water.

[0008] Preferably, the steam accumulator is equipped with a steam-water separator; the steam-water separator reduces the water content of the steam being delivered to the outside as much as possible.

[0009] Preferably, the steam inlet pipe, steam accumulator, superheater inlet pipe, superheater, and superheater outlet pipe are connected in sequence; this facilitates the sequential passage of steam through the steam inlet pipe, steam accumulator, superheater inlet pipe, superheater, and superheater outlet pipe.

[0010] Preferably, the steam inlet pipe is connected to the steam accumulator, the superheater inlet pipe is connected to the steam accumulator, the superheater inlet pipe is connected to the superheater, and the superheater is connected to the superheater outlet pipe using flanges and bolts; this improves the ease of installation and disassembly.

[0011] Preferably, the superheater inlet pipe is connected to the superheater and the superheater outlet pipe are both connected using flanges that are built into the steam accumulator; this improves the ease of assembly.

[0012] Preferably, the steam accumulator is equipped with an inlet valve at the steam inlet and an outlet valve at the steam outlet, and both the inlet and outlet of the steam accumulator are also equipped with check valves; this improves the convenience of controlling the steam inlet and outlet of the steam accumulator.

[0013] Preferably, the steam accumulator is equipped with a water supply valve and a water drain valve, and a liquid level sensor is installed inside the steam accumulator to facilitate control of the liquid level inside the steam accumulator.

[0014] Preferably, the superheater is equipped with a heat exchange tube bundle inside, and the heat source used by the superheater is high-temperature and high-pressure saturated water inside the steam accumulator; this facilitates the superheating of saturated steam.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: saturated steam is transported to the steam accumulator through the steam inlet pipe, so that the steam accumulator stores the saturated steam. When needed, the saturated steam is discharged into the superheater through the superheater inlet pipe, where it is heated to form superheated steam. The superheated steam is then discharged through the superheater outlet pipe. This facilitates the continuous maintenance of saturated steam during long-distance transportation, improves the steam quality at the receiving point, and reduces the generation of condensate.

[0021] Example: Figures 1 to 3 As shown, a steam heat storage self-superheating system includes a steam heat storage unit 1; it also includes a steam inlet pipe 2, a superheater inlet pipe 5, a superheater 6, and a superheater outlet pipe 7. One end of the steam inlet pipe 2 is installed on the steam heat storage unit 1, the superheater 6 is installed in the steam heat storage unit 1, and the superheater 6 communicates with the interior of the steam heat storage unit 1 through the superheater inlet pipe 5. One end of the superheater outlet pipe 7 is installed on the superheater 6, and the other end of the superheater outlet pipe 7 extends to the outside of the steam heat storage unit 1.

[0022] The steam accumulator 1 is equipped with an internal accumulator component 3. The steam accumulator 1 is provided with a steam inlet and a steam outlet. One end of the steam inlet pipe 2 and one end of the internal accumulator component 3 are both installed on the steam inlet of the steam accumulator 1. One end of the superheater inlet pipe 5 is installed on the steam outlet of the steam accumulator 1.

[0023] The steam accumulator 1 is equipped with a steam-water separator 4 inside;

[0024] The steam inlet pipe 2, steam accumulator 1, superheater inlet pipe 5, superheater 6, and superheater outlet pipe 7 are connected in sequence.

[0025] The steam inlet pipe 2 is connected to the steam accumulator 1, the superheater inlet pipe 5 is connected to the steam accumulator 1, the superheater inlet pipe 5 is connected to the superheater 6, and the superheater 6 is connected to the superheater outlet pipe 7 by means of flange and bolt.

[0026] The superheater inlet pipe 5 is connected to the superheater 6 and the superheater 6 is connected to the superheater outlet pipe 7 using the flanges that are built into the steam accumulator 1.

[0029] The superheater 6 is equipped with a heat exchange tube bundle inside, and the heat source used by the superheater 6 is the high-temperature and high-pressure saturated water inside the steam accumulator 1.

[0030] Saturated steam is transported to steam accumulator 1 through steam inlet pipe 2, where it is stored. When needed, after dehumidification by steam-water separator 4, the saturated steam is discharged from steam accumulator 1 into superheater 6 through superheater inlet pipe 5.

This facilitates the continuous maintenance of saturated steam during long-distance transportation, improves the steam quality at the receiving point, and reduces condensate production.

[0031] In practical use:

[0032] When the pressure of the boiler and steam drum is higher than the set steam supply pressure, the steam inlet valve automatically opens to supply steam to the steam accumulator 1. When the pressure of the boiler and steam drum is lower than the set steam supply pressure, the steam inlet valve automatically closes to stop supplying steam to the steam accumulator 1. When the steam supply flow rate from the boiler and steam drum to the steam accumulator 1 is higher than the external steam supply, the steam accumulator 1 enters the charging state. When the steam supply flow rate from the boiler and steam drum to the steam accumulator 1 is lower than the external steam supply, the steam accumulator 1 enters the heat release state. When the liquid level in the steam accumulator 1 is higher than the set high liquid level value, the drain valve opens. When the liquid level is lower than the set high liquid level value, the drain valve closes. When the liquid level is lower than the set low liquid level value, the water supply valve opens. When the liquid level is higher than the set high liquid level value, the water supply valve closes.
