[0029] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0030] See also Figure 1 , Figure 1 It is a structural schematic diagram of the methanol delivery device provided in an embodiment of the present application.

[0031] The embodiment of the present application provides a methanol delivery device 100. The methanol delivery device 100 includes a storage tank 101, an outlet pump 102, a first storage tank 103, and a second storage tank 104, wherein the outlet of the storage tank 101 is connected to the delivery main pipe 110, the inlet of the first storage tank 103 is connected to the delivery main pipe 110 through the first delivery pipe 120, and the outlet pump 102 is arranged on the delivery main pipe 110 between the outlet of the storage tank 101 and the first delivery pipe 120; the outlet of the first storage tank 103 is connected to the inlet of the second storage tank 104 through the second delivery pipe 130, and the first delivery pipe 120 is connected to the second storage tank 104 through the third delivery pipe 140. At the same time, the delivery and exhaust of methanol fuel are realized, and the operation of the methanol fuel unloading pump 105 and its affiliated pipelines is stopped, which reduces the workload of operators in the process of methanol delivery while reducing maintenance and repair costs.

[0032] In some embodiments, the first delivery pipe 120 is provided with a first exhaust valve 121, a first storage tank valve 122, a first drain valve 123, and a second storage tank valve 124 in sequence along the direction from the outlet of the storage tank 101 to the inlet of the first storage tank 103; the first delivery pipe 120 is connected to the third delivery pipe 140 between the first exhaust valve 121 and the first storage tank valve 122. The first drain valve 123 is used for isolating and draining the first delivery pipe 120.

[0033] In some embodiments, a second exhaust valve 141 is disposed on the third delivery pipe 140 .

[0034] In some embodiments, the second delivery pipe 130 is provided with a first drain valve 131, a second drain valve 132 and a second drain valve 133 in sequence from the outlet of the first storage tank 103 to the inlet of the second storage tank 104. The second drain valve 132 is used for isolating and draining the first storage tank 103.

[0035] In some embodiments, the first storage tank 103 includes a liquid level meter 1031 for measuring the storage amount of methanol fuel; a feeding port 1032 , which is connected to the first storage tank 103 , and a feeding valve 1033 is provided between the feeding port 1032 and the first storage tank 103 .

[0036] Working principle: after receiving the request for methanol delivery, confirm that the operating indicators of the storage tank 101 and the outlet pump 102 are normal, open the first exhaust valve 121, then open the first storage tank valve 122 and the second storage tank valve 124, and deliver methanol to the first storage tank 103 through the first delivery pipe 120. By observing the liquid level gauge 1031 of the first storage tank 103 of the methanol fuel storage tank, when the liquid level reaches the required amount of methanol fuel, close the first exhaust valve 121, then close the first storage tank valve 122 and the second storage tank valve 124, and stop delivering methanol fuel to the first storage tank 103. According to the actual amount of methanol delivered, calculate the required additive amount, open the feeding valve 1033 and add the additive into the feeding port 1032; after the additive is added, close the feeding valve 1033.

[0037] Specifically, when the first storage tank 103 needs to be isolated and emptied due to maintenance tasks, the first drain valve 131 and the second drain valve 133 are opened, and the methanol in the first storage tank 103 is discharged to the second storage tank 104 through the second delivery pipe 130. The emptying of the first storage tank 103 is determined by observing the liquid level of the liquid level meter 1031. After emptying, the second drain valve 133 is closed, and the second drain valve 132 is opened to further confirm the emptying of the first storage tank 103. Then, further process isolation treatment is performed according to the specific maintenance tasks.

[0038] More specifically, when the first delivery pipe 120 has a maintenance task, the first exhaust valve 121 and the second storage tank valve 124 are closed, and then the first storage tank valve 122 and the second exhaust valve 141 are opened to discharge methanol to the second storage tank 104 through the third delivery pipe 140. After the first delivery pipe 120 is emptied, the second exhaust valve 141 and the first storage tank valve 122 are closed, and the first drain valve 123 is opened for further emptying confirmation. Then, further process isolation processing is performed according to the specific maintenance task.

The second backup pipe 160 is connected to the first backup pipe 150 between the first backup exhaust valve 152 and the backup storage tank valve 153. The second backup pipe 160 is connected to the third delivery pipe 140 between the second storage tank 104 and the second exhaust valve 141.

[0045] In some embodiments, a third backup pipe 170 is provided between the outlet backup pump 151 and the first backup exhaust valve 152 for connecting the first backup pipe 150 and the delivery main pipe 110 .

[0046] Specifically, when it is necessary to switch to the outlet standby pump 151, the first standby exhaust valve 152 and the second standby exhaust valve 161 are opened, and exhaust is discharged to the second storage tank 104 through the third delivery pipe 140. After the exhaust is completed, the outlet standby pump 151 is successfully switched.
