[0029] In one exemplary embodiment, such as Figure 1 As shown, this utility model provides a mobile gas supply station 100, including a mobile steam storage device 10 and a steam supply device 20.

[0030] The steam supply device 20 includes a steam distribution pipe 210 and a steam supply header 220; the steam supply header 220 is connected to the power generation boiler unit to receive steam generated by the power generation boiler unit; the steam distribution pipe 210 is connected to the steam supply header 220.

[0031] The mobile steam storage device 10 is used to connect to the steam distribution pipe 210 to obtain the steam output from the steam distribution pipe 210, and the mobile steam storage device 10 is able to store the steam and transport it to a predetermined area.

[0032] Optionally, the mobile steam storage unit 10 is equipped with steam storage equipment and a mobile platform, which can store and transport steam generated by the power generation boiler unit and deliver the steam heat source to areas with heating demand.

[0033] For example, the steam supply device 20 includes a steam distribution pipe 210 and a steam supply main pipe 220. One end of the steam distribution pipe 210 is connected to the steam supply main pipe 220, and the other end is provided with an interface suitable for quick connection to the mobile steam storage device 10. It is also equipped with auxiliary equipment such as valve groups, instrumentation and control facilities and metering flow meters to ensure that steam is delivered to the mobile steam storage device 10 in a controllable and metered manner.

[0034] The aforementioned mobile gas supply station 100 stores and transports steam via a mobile steam storage device 10, delivering the steam to any user location accessible by road. For development zones far from main power grids or with dispersed layouts, it provides a mobile energy storage heating source. A steam supply header 220 connects to a power generation boiler unit, receiving steam generated by the boiler unit. Steam distribution pipes 210 connect the mobile steam storage device 10 and the steam supply header 220, transmitting steam to the mobile steam storage device 10. This recovers surplus heat energy from the power plant boiler unit, converting it into a valuable steam heat source. This reduces the consumption of fossil fuels such as coal, reduces air pollution, improves energy efficiency, and promotes the development of the thermal power industry.

[0035] In one exemplary embodiment, such as Figure 1 As shown, the mobile steam storage device 10 includes a steam storage component 110 and a moving component 120.

[0036] The steam storage unit 110 is used to connect with the steam distribution pipe 210 and store the steam output from the steam distribution pipe 210; the moving part 120 can carry the steam storage unit 110 for movement.

[0037] For example, the mobile steam storage device 10 can be a storage vehicle, the steam storage component 110 can be a steam storage tank, and the mobile component 120 can be a heavy-duty truck platform. The design parameters of the mobile steam storage device 10 meet the following requirements: charging temperature ≤ 400℃, charging pressure 1–4 MPa, vehicle rated load capacity of approximately 50 tons, design pressure 2.5 MPa, design temperature 250℃, heat release temperature ≤ 180℃, and heat release pressure ≤ 1 MPa. This device adopts a mobile pressure vessel structure, facilitating road transportation and enabling flexible steam distribution from the power plant to the user end.

[0038] For example, the ground of the steam supply station needs to be hardened with a load-bearing capacity of not less than 50 tons, and the high-pressure water drainage trench in the site needs to be reinforced for about 40 meters to meet the safety requirements for the full-load parking and operation of the mobile steam storage unit 10. Safety warning signs and safe operating procedures should be set up at the steam supply station to ensure operational safety when the heat source is input into the mobile energy storage vehicle. The mobile steam supply station 100 can realize the efficient recovery and external supply of surplus steam from the power plant, significantly increasing the steam supply volume and having good energy-saving benefits and economic returns.

[0039] The following embodiments specifically describe the heat source distribution structure of this mobile gas supply station 100.

[0040] In one exemplary embodiment, such as Figure 1 As shown, the steam distribution pipe 210 is provided with multiple distribution sub-pipes 211 arranged at intervals, and multiple mobile steam storage devices 10 are provided, each of which can be connected to the distribution sub-pipe 211 in a corresponding manner.

[0041] In one exemplary embodiment, such as Figure 1 As shown, each distribution sub-pipe 211 is equipped with a first valve group 212, which is used to control the amount of steam input to the steam storage unit 110.

[0042] For example, the steam distribution pipe 210 is provided with a plurality of spaced-apart distribution sub-pipes 211, which are used to independently transmit steam to each steam storage unit 110 in the mobile steam storage device 10. The distribution sub-pipes 211 enable parallel steam charging, improve the steam charging efficiency, and adapt to mobile steam storage units of different capacities and specifications.

[0043] Each distribution sub-pipe 211 is equipped with a first valve group 212, which may include at least one regulating valve and a shut-off valve for precisely controlling the steam flow and pressure input to the corresponding steam storage unit 110, and can quickly cut off the steam supply in abnormal situations to ensure system safety.

[0044] In one exemplary embodiment, such as Figure 1 As shown, a second valve group 221 is provided on the steam supply header 220. The second valve group 221 is used to control the steam flow rate in the steam supply header 220.

[0045] In one exemplary embodiment, such as Figure 1 As shown, a steam flow meter 222 is installed on the steam supply header 220. The steam flow meter 222 is used to count the steam flow in the steam supply header 220.

[0046] A second valve group 221 can be installed on the steam supply header 220. The second valve group 221 is located between the steam source interface of the power plant and the steam distribution pipe 210. It is used to regulate the steam flow and pressure in the input steam supply header 220, realize centralized control of the output steam, and ensure that the header pressure is stable within the set range. A steam flow meter 222 is also installed on the steam supply header 220. It can be an intelligent flow meter with temperature and pressure compensation, used to monitor and count the total steam flow in the input steam supply header 220 in real time.

[0047] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the present invention also provides a mobile heating system, which includes a mobile gas supply station 100 according to any of the above embodiments.

[0048] For example, such as Figure 1 As shown, the area of ​​the mobile gas supply station 100 is 15000mm × 20000mm. The road is represented by X, and the distance between the centerline of the road and the edge of the opposite side of the mobile gas supply station 100 is not less than 25000mm.

[0049] In one exemplary embodiment, such as Figure 2 As shown, the mobile heating system also includes a first boiler unit 30, a first heating pipeline 40, and a second heating pipeline 50.

[0050] The first boiler unit 30 is equipped with a heating interface 310, which is connected to the first heating pipeline 40. The first heating pipeline 40 is connected to the second heating pipeline 50, and the second heating pipeline 50 is connected to the steam supply header 220.

[0051] For example, a thermal power plant has two phases of boiler units. Phase I includes two 320MW thermal power units, and Phase II includes two 1000MW thermal power units, with a total installed capacity of 2640MW. The mobile heating system includes a first boiler unit 30, a first heating pipeline 40, and a second heating pipeline 50. The first boiler unit 30 can be a large-capacity power generation boiler in the power plant (such as two 1000MW unit boilers). The first boiler unit 30 serves as a steam heat source, and a heating interface 310 is set at a suitable location in the first boiler unit 30, preferably on the boiler cold reheat steam pipeline. Specifically, it is set on the cold reheat steam pipeline between the temporary heating external heating control valve and the electric valve in front of the temporary heating external heating control valve of the first boiler unit 30, with an operating pressure range of 1.8–5.6MPa and a temperature of approximately 360±10℃.

[0052] One end of the first heating pipeline 40 is connected to the heating interface 310 to draw out the steam generated by the boiler. The first heating pipeline 40 can be an overhead-laid high-temperature and high-pressure alloy steel pipeline and can be laid along the existing pipe racks within the power plant, for example, a DN200 pipeline can be used. The second heating pipeline 50 connects to the first heating pipeline 40 and delivers steam to the designated steam charging area of ​​the mobile steam supply station 100. The specifications of the second heating pipeline 50 can be adjusted according to the final steam charging requirements, for example, it can be converted to a DN150 or DN65 pipeline near the steam charging station, and equipped with corresponding quick-connect interfaces, safety valves and control valves to achieve quick and safe docking with the mobile steam storage device 10.

[0053] For example, taking the first boiler unit 30 as two 1000MW boiler units, the above-mentioned mobile heating system adds 17,280 tons / year of steam supply (calculated at a pressure of 0.45Mpa and a temperature of 155℃). The heating price is calculated at 170 yuan / ton, generating 2.9376 million yuan in benefits annually. This effectively improves energy utilization efficiency, can continuously provide the necessary steam for the region, and promotes the development of the thermal power industry.

[0054] The aforementioned mobile heating system, by integrating efficient mobile steam supply units, enables the safe, flexible, and controllable delivery of surplus high-temperature and high-pressure steam generated by large thermal power generating units to remote users, effectively improving the overall energy utilization efficiency and economic benefits of power plants.

[0055] In one exemplary embodiment, such as Figure 2 As shown, a third valve group 410 is provided between the first heating pipeline 40 and the second heating pipeline 50. The third valve group 410 is used to control the steam flow rate in the second heating pipeline 50.

[0056] In one exemplary embodiment, such as Figure 2 As shown, a fourth valve group 510 is provided between the second heating pipeline 50 and the steam supply header 220. The fourth valve group 510 is used to control the steam flow rate input to the steam supply header 220.

[0057] For example, a third valve group 410 is provided between the first heating pipeline 40 and the second heating pipeline 50 for controlling and regulating the steam flow rate and pressure delivered from the first heating pipeline 40 to the second heating pipeline 50. The third valve group 410 may include an electric regulating valve, a manual isolation valve, and a bypass valve, etc., and the multi-valve control ensures that the system can still operate reliably when the main regulating valve fails or is under maintenance. By adjusting the third valve group 410, the steam parameters can be smoothly adjusted to a suitable charging range according to the real-time needs of the mobile gas supply station 100 and the operating conditions of the power plant, ensuring the stability and safety of the delivery process.

[0058] A fourth valve group 510 is also installed between the second heating pipeline 50 and the steam supply header 220 to control the instantaneous flow rate and cumulative total amount of steam ultimately input to the mobile steam storage device 10. The fourth valve group 510 may include a flow meter, an electric / manual regulating valve, and an emergency shut-off valve to ensure the safety, efficiency, and accuracy of each filling operation.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
