Description

Technical Field

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

[0002] Steam accumulators are devices that effectively solve the problem of fluctuating steam load by storing surplus steam and releasing it during peak demand periods. Existing steam accumulators, such as the constant-temperature steam accumulator disclosed in patent CN208936130U and the vertical steam accumulator disclosed in patent CN112325689B, can all achieve the storage of surplus steam and release during peak demand periods.

[0003] However, during use, it was found that the existing steam accumulators have a relatively simple structure. During long-distance transportation, the steam temperature is lower than the saturation temperature under the current pressure, which leads to condensation and a decrease in steam quality. Furthermore, the condensate accumulates at low points in the pipeline or is pushed by the steam during high-speed flow, which can easily cause water hammer, damaging the pipeline and equipment and resulting in poor practicality. Therefore, there is an urgent need for a steam heat storage and self-superheating system that utilizes its own heat source to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steam heat storage and self-superheating system that utilizes its own heat source. Steam is discharged into a superheater through an intake pipe, where it is heated to form superheated steam. The superheated steam is then discharged through an outlet pipe, or it is discharged into a steam accumulator through an intake pipe, where it stores the heat energy in the steam. When needed, steam is discharged from the steam accumulator into the superheater, and the above steps are repeated to form superheated steam, which is then discharged through an outlet pipe. This ensures the quality of the discharged steam, facilitates long-distance steam transportation, and improves the practicality of the equipment.

[0005] This utility model discloses a steam heat storage and superheating system utilizing its own heat source, including a steam accumulator; it also includes an inlet pipe, a superheater, and an outlet pipe. The inlet pipe and the superheater are both installed on the steam accumulator, and the outlet pipe is installed on the superheater. The two sets of outlet ends of the inlet pipe are respectively connected to the interior of the steam accumulator and the superheater.

[0006] Steam is introduced into the superheater through the intake pipe, where it is heated to form superheated steam. The superheated steam is then discharged through the outlet pipe, or it can be discharged into a steam accumulator through the intake pipe, where it stores the heat energy in the steam. When needed, the steam is discharged from the steam accumulator into the superheater, and the above steps are repeated to form superheated steam, which is then discharged through the outlet pipe. This process ensures the quality of the discharged steam, facilitates long-distance steam transportation, and improves the practicality of the equipment.

[0007] Preferably, the steam accumulator is provided with a steam inlet and a steam outlet. A set of outlet ends of the air inlet pipe is connected to the steam inlet of the steam accumulator. The steam accumulator is provided with internal components and a steam-water separator. The top of the internal components is connected to the steam inlet of the steam accumulator. The air inlet pipe discharges steam into the internal components of the accumulator, so that the steam and water can fully exchange heat. When the steam accumulator discharges steam, the steam-water separator reduces the water content of the steam being transported out as much as possible.

[0008] Preferably, the steam accumulator and the air inlet pipe, the steam accumulator and the superheater, the air inlet pipe and the superheater, and the superheater and the steam outlet pipe are all connected by flanges and bolts, which improves the convenience of maintenance.

[0009] Preferably, both the steam inlet and steam outlet of the steam accumulator are equipped with check valves to prevent steam backflow.

[0010] Preferably, an inlet valve is provided at the connection between the air inlet pipe and the steam accumulator, and an outlet valve is provided at the connection between the steam accumulator and the superheater; this facilitates the control of the steam inlet and outlet of the steam accumulator.

[0011] Preferably, the steam accumulator is equipped with a water supply valve and a water drain valve to facilitate control of the liquid level in the steam accumulator.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This system regulates the boiler load through a steam accumulator to ensure the stable operation of the boiler, and heats the discharged saturated steam through a superheater to turn the saturated steam into superheated steam, thereby improving the steam quality, reducing steam loss during long-distance transportation, and improving the steam supply capacity.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] Example: Figures 1 to 3 As shown, a steam heat storage and superheating system utilizing its own heat source includes a steam accumulator 1; it also includes an inlet pipe 2, a superheater 5, and an outlet pipe 6. The inlet pipe 2 and the superheater 5 are both installed on the steam accumulator 1, and the outlet pipe 6 is installed on the superheater 5. The two sets of outlet ends of the inlet pipe 2 are respectively connected to the interior of the steam accumulator 1 and the superheater 5.

[0019] The steam accumulator 1 is provided with a steam inlet and a steam outlet. A set of outlet ends of the air inlet pipe 2 is connected to the steam inlet of the steam accumulator 1. The steam accumulator 1 is provided with an internal accumulator component 3 and a steam-water separator 4. The top of the internal accumulator component 3 is connected to the steam inlet of the steam accumulator 1.

[0020] The steam accumulator 1 and the air inlet pipe 2, the steam accumulator 1 and the superheater 5, the air inlet pipe 2 and the superheater 5, and the superheater 5 and the steam outlet pipe 6 are all connected by flanges and bolts.

[0021] The steam accumulator 1 is equipped with check valves at both the steam inlet and the steam outlet.

[0022] A steam inlet valve is provided at the connection between the air inlet pipe 2 and the steam accumulator 1, and a steam outlet valve is provided at the connection between the steam accumulator 1 and the superheater 5.

[0023] The steam accumulator 1 is equipped with a water supply valve and a water drain valve;

[0024] When the pressure of the boiler and steam drum is higher than the set steam supply pressure, the steam inlet valve automatically opens, and the steam inlet pipe 2 supplies 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, the steam inlet pipe 2 stops supplying steam to the steam accumulator 1, and the steam inlet pipe 2 continues to supply steam to the superheater 5, so that the superheater 5 heats the steam to form superheated steam, which is then discharged into the main pipeline through the steam outlet pipe 6. When the steam supply flow rate from the boiler and steam drum to the steam accumulator 1 is higher than the external steam supply flow rate, 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. After being dehumidified by the steam-water separator 4, the steam enters the superheater 5, which heats the steam to form superheated steam. The superheated steam is then discharged into the main pipeline through the steam outlet pipe 6. 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.
