Description

Technical Field

[0002] In existing technologies, pressure sensors are typically used to monitor pressure changes within methanol storage tanks in real time. These sensors can accurately measure the pressure value within the tank and transmit the data to the control system for further processing. Secondly, regarding flow control, existing technologies may employ valves or similar devices to regulate the flow of methanol gas in pipelines. By controlling the opening degree of the valve, precise regulation of the methanol gas flow rate can be achieved, thereby ensuring that the pressure within the storage tank is maintained within a safe range. However, compared to this patent, existing technologies may be insufficient in terms of automation and flexibility. For example, valves in existing technologies usually require manual operation or rely on preset fixed programs for adjustment, and cannot be automatically adjusted according to real-time pressure changes within the storage tank. Furthermore, existing technologies may lack an effective solution for pressure balancing among multiple storage tanks.

[0023] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, this application provides a methanol storage tank pressure detection system, including a vaporization device 1, at least two temporary storage tanks 2, and a regulating device 4. The regulating device 4 selectively connects the vaporization device 1 to the temporary storage tank 2 according to the pressure inside the temporary storage tank 2, so as to regulate the pressure of the temporary storage tank 2.

[0025] Furthermore, the regulating device 4 is provided with at least three connection ports 10, including one air inlet connection port and at least two air outlet connection ports. The air inlet connection port is connected to the gasification device 1, and the air outlet connection ports are respectively connected to the corresponding temporary storage tanks 2.

[0026] In this embodiment, the methanol storage pressure detection system includes a vaporization device 1, at least two temporary storage tanks 2, and a regulating device 4. The regulating device 4 is provided with at least three connection ports 10, and all three connection ports 10 are connected to at least two temporary storage tanks 2 and a vaporization device 1 through flanges 11.

[0027] The regulating device 4 and the gasification device 1 are connected by an air inlet and an air inlet pipe. The methanol gas in the gasification device 1 enters the regulating device 4 through the air inlet pipe and the air inlet. The regulating device 4 is connected to at least two temporary storage tanks 2 through an air outlet and an air inlet pipe, respectively.

[0028] Specifically, the regulating device 4 is connected to the first temporary storage tank 2 via the first pipe 201 and one of the gas outlet ports; and to the second temporary storage tank 2 via the second pipe 202 and the other gas outlet port. The vaporization device 1 delivers the vaporized methanol sequentially through the inlet pipe, the inlet port, the regulating device 4, the first gas outlet port, and the first pipe 201 into the first temporary storage tank 2. When the pressure in the first temporary storage tank 2 reaches the set value, the regulating device 4 adjusts the pressure, cutting off the connection between the vaporization device 1 and the first temporary storage tank 2, preventing methanol gas from entering the first temporary storage tank 2.

[0029] Meanwhile, the vaporization device 1 is connected to the second temporary storage tank 2. The vaporized methanol gas in the vaporization device 1 is sequentially transported to the second temporary storage tank 2 through the inlet pipe, inlet connection port, regulating device 4, second outlet connection port, and second pipe 202. This prevents the first temporary storage tank 2 from storing too much methanol gas, which could cause excessive pressure and reduce the airtightness of the first temporary storage tank 2 or even cause it to rupture, resulting in methanol leakage into the air. When the pressure in the second temporary storage tank 2 reaches the set value, the regulating device 4 adjusts it again to ensure the pressure in each temporary storage tank 2 remains stable.

[0030] Furthermore, the adjustment device 4 includes a housing 402, an adjustment mechanism disposed inside the housing 402, and a drive unit disposed outside the housing 402, wherein the drive unit drives the adjustment mechanism to rotate; By rotating the adjustment mechanism, the gasification device 1 can selectively connect to one of the temporary storage tanks 2 through the corresponding gas outlet.

[0031] In this embodiment, the regulating device 4 includes a housing 402, an regulating mechanism, and a driving unit. When it is necessary to switch the connection state between the vaporization device 1 and the temporary storage tank 2, the driving unit drives the regulating mechanism to rotate. By rotating the regulating mechanism, the opening and closing of different gas outlets can be realized, so that methanol gas can enter the corresponding temporary storage tank 2 through different gas outlets.

[0032] In this embodiment, a stepper motor 401 is selected as the drive unit and is located at the center of the exterior of the housing 402. To facilitate the installation and removal of the adjustment device 4, a sealing shell 12 is provided on the outer side of the stepper motor 401. The sealing shell 12 is detachably mounted on the housing 402 of the adjustment device 4 via a mounting nut 13. The sealing shell 12 effectively prevents methanol gas from leaking into the air between the power output end of the stepper motor 401 and the housing 402 of the adjustment device 4.

[0033] Furthermore, the housing 402 is provided with an air inlet, which is connected to the vaporization device 1 through the air inlet connection port; At least two of the vent holes are connected to the temporary storage tank 2 through corresponding vent ports.

[0034] In this embodiment, the housing 402 is provided with an air inlet, a first air outlet 406, and a second air outlet 407. The air inlet is connected to the vaporization device 1 through an air inlet connection port, the first air outlet 406 is connected to the first temporary storage tank 2 through a first air outlet connection port, and the second air outlet 407 is connected to the second temporary storage tank 2 through a second air outlet connection port. Only one connection method between the air outlet and the temporary storage tank 2 is shown here; in practical applications, it can be adjusted as needed.

[0035] Furthermore, the adjusting device 4 is also provided with an upper annular limiting plate 5 and a lower annular limiting plate 6; the upper and lower edges of the end of the adjusting mechanism rotate along the upper annular limiting plate 5 and the lower annular limiting plate 6, respectively.

[0036] Furthermore, the adjustment mechanism includes: a rotating shaft 408, a baffle 403, and an arc-shaped plate 404; the baffle 403 is vertically arranged, the rotating shaft 408 is located at the center of the baffle 403 in the horizontal direction, and the arc-shaped plate 404 is located at both ends of the baffle 403.

[0037] In this embodiment, the adjusting device 4 has a circular structure, the baffle 403 is arranged along the diameter of the adjusting device 4, and the upper and lower edges of the baffle 403 are provided with adjusting mechanism limiting plates 8 to ensure the stability of the baffle 403; the rotating shaft 408 is vertically arranged in the adjusting device 4 and is located at the center of the baffle 403 to ensure that the baffle 403 can rotate smoothly and at a constant speed on both sides; the arc plate 404 is arranged at both ends of the baffle 403, and the upper and lower sides of the arc plate 404 are also provided with adjusting mechanism limiting plates 8 to ensure that the arc plate 404 fits with the upper annular limiting plate 5 and the lower annular limiting plate 6 to prevent gas leakage.

[0038] Furthermore, the arc-shaped plate 404 is provided with air holes, and an air hole limiting plate 9 is provided on one side of the air hole; When the end of the arc-shaped plate 404 abuts against the air outlet limiting plate 9, the air hole is aligned with the air outlet, and the vaporization device 1 is connected to the corresponding temporary storage tank 2.

[0039] In this embodiment, the arc plate 404 is located on opposite sides of the baffle 403, and the air holes provided on the arc plate 404 are on the same side relative to the baffle 403. That is, the positions of the air holes provided on the two arc plates 404 relative to the baffle 403 are both located on the right side of the baffle 403 or both located on the left side of the baffle 403, while no air holes are provided on the other side.

[0040] Furthermore, sealing units are provided on both sides of the air outlet, and the sealing units have an arc-shaped structure.

[0041] Furthermore, the two sides of the sealing unit are inclined surfaces at a 45°~60° angle toward the center.

[0042] In this embodiment, the sealing unit uses a felt sealing gasket 7. In actual applications, felt sealing strips, limiting plates, and sealing shells can be selected as needed to ensure the sealing and safety during gas transportation.

[0043] Furthermore, the methanol storage tank pressure detection system also includes: A pressure monitoring device is used to monitor the pressure inside the temporary storage tank 2; a control device receives the monitoring results from the pressure monitoring device and controls the regulating device 4 to switch the connection status between the gasification device 1 and the temporary storage tank 2 according to the monitoring results.

[0044] In this embodiment, the adjusting device 4 is provided with an upper annular limiting plate 5 and a lower annular limiting plate 6, which are specifically fixed on the housing 402. The arrangement of the upper annular limiting plate 5 and the lower annular limiting plate 6 can ensure that the adjusting mechanism remains stable when rotating.

[0045] It should be noted that the pressure monitoring device in this embodiment is pressure sensor 3. In actual production applications, a suitable device can be selected to monitor the pressure.

[0046] Specifically, the stepper motor 401 operates, driving the rotating shaft 408 to rotate. While rotating, the rotating shaft 408 drives the baffle 403 connected to the rotating shaft 408 to rotate, thereby driving the arc plate 404 to rotate stably along the upper annular limiting plate 5 and the lower annular limiting plate 6.

[0047] During the rotation of the baffle 403, when the arc plate 404 near the first vent 406 rotates to the first vent 406 and abuts against the vent limiting plate 9 on one side of the first vent 406, the vent 405 on the arc plate 404 near the first vent 406 connects with the first vent 406, and the vaporization device 1 transports the vaporized methanol to the first temporary storage tank 2 through the first pipeline 201. Meanwhile, the arc-shaped plate 404 without vent 405 contacts the felt sealing gasket 7 on one side of the first vent 406 to prevent gas leakage between the arc-shaped plate 404 and the housing 402; the vent 405 on the arc-shaped plate 404 near the second vent 407 contacts the felt sealing gasket 7 on one side of the second vent 407 to prevent gas leakage between the vent 405 on the arc-shaped plate 404 near the second vent 407 and the housing 402, and the arc-shaped plate 404 near the second vent 407 contacts the felt sealing gaskets 7 on both sides of the second vent 407 to block the second vent 407.

[0048] During the process of supplying methanol gas to the first temporary storage tank 2, the pressure sensor 3 installed on the first temporary storage tank 2 monitors the pressure inside the first temporary storage tank 2. When the pressure in the first temporary storage tank 2 reaches the set value, the pressure sensor 3 sends a signal to the control device, and the control device controls the stepper motor 401 to rotate. At this time, the baffle 403 rotates counterclockwise, and the air hole 405 on the arc plate 404 near the first air outlet 406 is not connected to the first air outlet 406, so that the methanol gas does not enter the first temporary storage tank 2 connected to the first pipeline 201.

[0049] The arc-shaped plate 404 near the second vent 407 rotates to the vent limiting plate 9 on one side of the second vent 407. The vent 405 on the arc-shaped plate 404 near the second vent 407 is connected to the second vent 407, transporting the vaporized methanol to the second temporary storage tank 2 connected to the second pipeline 202. This prevents the first temporary storage tank 2 from storing too much methanol gas, which could cause excessive pressure inside the tank, reduce the airtightness of the first temporary storage tank 2, or cause the first temporary storage tank 2 to rupture, resulting in methanol leakage into the air.

[0050] Meanwhile, the arc-shaped plate 404 without vent 405 contacts the felt sealing gasket 7 on one side of the second vent 407 to prevent gas leakage between the arc-shaped plate 404 and the housing 402; the vent 405 on the arc-shaped plate 404 near the first vent 406 contacts the felt sealing gasket 7 on one side of the first vent 406 to prevent gas leakage between the vent 405 on the arc-shaped plate 404 near the first vent 406 and the housing 402; the arc-shaped plate 404 near the first vent 406 contacts the felt sealing gaskets 7 on both sides of the first vent 406 to block the first vent 406.

[0051] The methanol storage tank pressure detection system of this application combines pressure monitoring, automatic control and sealing technology. By monitoring the pressure in the temporary storage tank 2 in real time and automatically adjusting the transport route of methanol gas, it achieves effective control of the pressure in the temporary storage tank 2, thereby avoiding the occurrence of safety risks caused by excessive pressure.
