[0002] Mobile energy storage heating is an important application aspect in the field of energy storage technology. Specifically, it recycles the surplus energy and industrial waste heat from high-energy-consuming industries such as electricity, comprehensive waste disposal, smelting, chemical industry, and building materials using existing high-efficiency energy storage devices for storage and then transports them to heat users such as textile companies, pharmaceutical companies, chemical companies, schools, hotels, and residential communities by mobile transportation to provide steam and hot water.

[0003] The boost system is an important component of the mobile energy storage heating system. For example, the Chinese patent number CN219530566U discloses a vehicle unloading boost system for mobile energy storage heating. However, the patent solution still has some shortcomings:

However, the use of steam at the user end has uncertain time and amount, and thus cannot guarantee that the high-pressure steam can evacuate the low-pressure steam when passing through the steam ejector, and cannot effectively utilize the low-pressure steam. Due to the uncertainty of time, the turnover efficiency of the mobile energy storage heating vehicle will also be reduced. At the same time, the above patent scheme requires at least three mobile energy storage heating vehicles to ensure stable operation, which has high investment costs and high operating costs.

[0060] The terminal boosting system designed in this application for mobile energy storage heating has the following beneficial effects:

[0061] 1. When the steam pressure of a mobile energy storage heating vehicle is low, its steam can be input into the steam ejector 11 and mixed with the steam with a higher steam pressure input from another mobile energy storage heating vehicle, so as to quickly utilize the low-pressure steam without waiting too much time, thereby improving turnover efficiency.

[0062] 2. With the cooperation of the first delivery pipe group, the second delivery pipe group, the steam ejector 11 and the steam buffer tank 6, the present application only needs two mobile energy storage heating vehicles to achieve continuous gas supply and reduce investment costs and operating costs.

[0063] The present application is not limited to the first and second delivery pipe groups, but may also include a third delivery pipe group, a fourth delivery pipe group, an n+2th delivery pipe group, etc. The pipe group composition is the same as the first and second delivery pipe groups, and will not be elaborated on; by increasing the number of delivery pipe groups, the number of connected mobile energy storage heating vehicles can be increased, without specific limitation.

[0064] The above is an embodiment of the present application of a terminal boost system for mobile energy storage heating. The following is an embodiment of the present application of a terminal boost system for mobile energy storage heating. For details, please refer to Figure 1 .

[0065] Based on the solution of the above embodiment 1:

[0066] Furthermore, the other end of the first high-pressure steam delivery pipe a1 and the other end of the first low-pressure steam delivery pipe a2 are respectively connected to the pipe wall of the first straight pipe a3, and are both connected to the first heating vehicle connecting pipe d1 through the first straight pipe a3. That is, the first high-pressure steam delivery pipe a1 and the first low-pressure steam delivery pipe a2 are connected to the first straight pipe a3, and the pipeline layout is more compact.

[0067] Furthermore, the other end of the second high-pressure steam delivery pipe c3 and the other end of the second low-pressure steam delivery pipe c2 are respectively connected to the pipe wall of the second direct delivery pipe c1, and are both connected to the second heating vehicle connecting pipe d2 through the second direct delivery pipe c1. That is, the second high-pressure steam delivery pipe c3 and the second low-pressure steam delivery pipe c2 are connected to the second direct delivery pipe c1, and the pipeline layout is more compact.

[0068] Further, taking the closed design of one end of the user connection pipe 8 as an example, the other end of the first direct delivery pipe a3, the other end of the second direct delivery pipe c1 and the other end of the second buffer delivery pipe b2 are all connected to the pipe wall of the user connection pipe 8 to achieve the connection with the user connection pipe 8. The user connection pipe 8 is used to connect the user end use pipe to supply steam to the user.

[0069] Furthermore, the first valve 2, the second valve 3, the third valve 4, the fourth valve 5, the fifth valve 7, the sixth valve 9, the seventh valve 10 and the eighth valve 12 are all electrically controlled valves, which are more convenient to control. Moreover, the valve type is not limited to a straight-through valve, and can also be a three-way valve, a four-way valve, etc.

[0070] Furthermore, the first heating vehicle connecting pipe d1 and the second heating vehicle connecting pipe d2 are both provided with a first pressure sensor (not shown) for detecting their internal pressure. In conjunction with the mobile energy storage heating vehicle's built-in pressure detection module, the internal steam pressure of the mobile energy storage heating vehicle can be more accurately determined.

[0071] Furthermore, there are at least two steam buffer tanks 6; the input end of each steam buffer tank 6 is connected to the steam ejector 11 through the first buffer delivery pipe b1; the output end of each steam buffer tank 6 is connected to the user connection pipe 8 through the second buffer delivery pipe b2. The design of multiple steam buffer tanks 6 can achieve a larger capacity of steam buffer, while avoiding the problem of steam supply interruption caused by the failure of a single steam buffer tank 6.

[0072] Furthermore, each steam buffer tank 6 is provided with a second pressure sensor (not shown in the figure) for detecting its own internal pressure. The second pressure sensor is used to determine whether the steam buffer tank 6 has reached the cache upper limit, so that when a steam buffer tank 6 reaches the cache upper limit, it can be switched to other empty steam buffer tanks 6 for caching in time.

[0073] The above is a detailed introduction to a terminal boost system for mobile energy storage heating provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
