Description

Technical Field

[0001] This utility model relates to the field of methanol volatile gas recovery technology, specifically a methanol volatile gas recovery device. Background Technology

[0002] Methanol is a volatile substance and is toxic. When methanol-based fuel is dispensed into sales containers or transport vehicles through a dispensing machine, the volatile methanol gas needs to be recovered to avoid methanol volatile gas polluting the atmosphere.

[0003] In the prior art, the authorized patent CN221867935U discloses a methanol volatile gas recovery device, which includes a recovery tank, a circulating spray unit, a vacuum pump, and a drain pump. A water supply pipe is provided at the top of the recovery tank. An alcohol gas discharge pipe is provided inside the recovery tank, located below the spray pipe, and connected to the alcohol gas recovery pipe. An air outlet is also provided at the top of the recovery tank, connected to the air inlet of the vacuum pump via an exhaust pipe. A drain port is provided at the bottom of the recovery tank, connected to the inlet of the drain pump via a drain pipe. This novel methanol volatile gas recovery device can recover methanol volatile gas during the filling process of alcohol-based fuels, avoiding the problem of methanol volatile gas polluting the air; moreover, the recovery device has a simple structure and low cost.

[0004] However, the above technical solution still has the following shortcomings in actual use: the above device sets the alcohol gas discharge pipe below the spray seat, and the alcohol gas is discharged through the exhaust pipe before it is fully dissolved with the water, which greatly reduces the alcohol gas recovery effect. In this regard, we propose a methanol volatile gas recovery device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a methanol volatile gas recovery device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a methanol volatile gas recovery device, comprising:

[0007] A recycling tank is provided with a vacuum pump on one side, on which an alcohol gas suction pipe and an alcohol gas delivery pipe are fixedly installed. The end of the alcohol gas delivery pipe away from the vacuum pump is installed inside the recycling tank, and an exhaust pipe with multiple exhaust holes is provided at the end of the alcohol gas delivery pipe. A circulating water pump is provided on the other side of the recycling tank, on which an inlet pipe is fixedly installed. The inlet pipe is fixedly installed on the recycling tank, and a drain pipe is fixedly installed on the circulating water pump. The end of the drain pipe away from the circulating water pump is installed inside the recycling tank, and a spray base with multiple evenly distributed nozzles is fixedly installed at the end of the drain pipe away from the circulating water pump. An exhaust pipe is installed at the top of the recycling tank.

[0008] Preferably, a drive motor is fixedly installed at the bottom of the recovery tank, and a rotating rod is driven to the output end of the drive motor. The top end of the rotating rod is fixedly welded to the bottom wall of the exhaust pipe, and the exhaust pipe is rotatably installed at the end of the alcohol gas conveying pipe.

[0009] Preferably, multiple stirring rods are fixedly welded onto the exhaust pipe.

[0010] Preferably, an L-shaped baffle is fixedly welded to the inner wall of the recycling tank at the end of the water inlet pipe.

[0011] Preferably, an injection pipe is fixedly installed on the rear side wall of the recovery tank, and a drain pipe is fixedly installed on the recovery tank. Both the injection pipe and the drain pipe are equipped with valves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In use, this utility model uses a vacuum pump, an alcohol gas suction pipe, and an alcohol gas delivery pipe to transport methanol volatile gas to an exhaust stack. The methanol volatile gas is then discharged into the water through multiple exhaust holes. As the methanol volatile gas forms bubbles in the water and rises, it can dissolve. The water is then transported to a spray station by a circulating water pump and sprayed by multiple nozzles. This allows any undissolved methanol volatile gas to dissolve again as it rises, resulting in more complete dissolution of the methanol volatile gas and water, thus improving the recovery efficiency.

[0014] 2. The drive motor provided in this utility model can drive the exhaust pipe to rotate at a constant speed during the exhaust process through the rotating rod, thereby adjusting the direction of the exhaust hole on the exhaust pipe, so as to facilitate the discharge of alcohol gas into the water liquid at different positions, improve the effect of dissolving methanol volatile gas in the water liquid, and drive multiple stirring rods to rotate when the exhaust pipe rotates to stir the water liquid, further improving the effect of dissolving and mixing methanol volatile gas with water liquid.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a methanol volatile gas recovery device, comprising:

[0021] A recycling tank 1 is provided with a vacuum pump 2 on one side. An alcohol gas suction pipe 3 is fixedly installed on the vacuum pump 2. The alcohol gas suction pipe 3 is connected to the filling tank of the alcohol-based fuel filling machine and the loading arm of the alcohol-based fuel. An alcohol gas delivery pipe 4 is fixedly installed on the vacuum pump 2. The end of the alcohol gas delivery pipe 4 away from the vacuum pump 2 is installed in the inner cavity of the recycling tank 1. An exhaust pipe 5 is provided at the end of the alcohol gas delivery pipe 4. The exhaust pipe 5 has multiple exhaust holes 6. A circulating water pump 7 is provided on the other side of the recycling tank 1. An inlet pipe 8 is fixedly installed on the circulating water pump 7. The inlet pipe 8 is fixedly installed on the recycling tank 1. A drain pipe 9 is fixedly installed on the circulating water pump 7. The end of the drain pipe 9 away from the circulating water pump 7 is installed in the inner cavity of the recycling tank 1. A spray seat 10 is fixedly installed at the end of the drain pipe 9 away from the circulating water pump 7. Multiple evenly distributed nozzles are installed on the spray seat 10. An exhaust pipe 11 is installed at the top of the recycling tank 1.

[0022] A drive motor 12 is fixedly installed at the bottom of the recovery tank 1. The output end of the drive motor 12 is connected to a rotating rod 13. The top end of the rotating rod 13 is fixedly welded to the bottom wall of the exhaust pipe 5. The exhaust pipe 5 is rotatably installed at the end of the alcohol gas conveying pipe 4. The drive motor 12 can drive the exhaust pipe 5 to rotate at a constant speed through the rotating rod 13, thereby adjusting the direction of the exhaust hole 6 on the exhaust pipe 5, so as to facilitate the discharge of alcohol gas into the water at different locations and improve the effect of dissolving alcohol gas in the water.

[0023] Multiple stirring rods 14 are fixedly welded onto the exhaust pipe 5. When the exhaust pipe 5 rotates, it can drive the multiple stirring rods 14 to rotate to stir the water liquid, so that when the alcohol gas rises in the water liquid, it can be fully dissolved and mixed with the water liquid.

[0024] An L-shaped baffle 15 is fixedly welded to the inner wall of the recovery tank 1 at the end of the water inlet pipe 8. The L-shaped baffle 15 can prevent the water inlet pipe 8 from sucking in undissolved alcohol gas along with the water.

[0025] A liquid injection pipe 16 is fixedly installed on the rear side wall of the recycling tank 1, and a liquid drain pipe 17 is fixedly installed on the recycling tank 1. Both the liquid injection pipe 16 and the liquid drain pipe 17 are equipped with valves 18. The liquid injection pipe 16 facilitates the injection of water into the recycling tank 1, and the liquid drain pipe 17 facilitates the discharge of saturated water.

[0026] Working principle: In use, the methanol vapor is transported to the exhaust stack 5 via the vacuum pump 2, alcohol gas suction pipe 3, and alcohol gas delivery pipe 4. The vapor is then discharged into the water through multiple exhaust holes 6, allowing it to dissolve as bubbles rise in the water. The water is then transported to the spray seat 10 via the circulating water pump 7 and sprayed through multiple nozzles. Any undissolved methanol vapor is further dissolved as it rises, resulting in more complete dissolution and improved recovery efficiency. The drive motor 12 rotates the exhaust pipe 5 at a constant speed during the exhaust process via the rotating rod 13, adjusting the direction of the exhaust holes 6 on the exhaust pipe 5 to direct the alcohol gas to different locations in the water, further enhancing the dissolution of methanol vapor in the water. The rotation of the exhaust stack 5 also drives multiple stirring rods 14 to agitate the water, further improving the mixing effect of the methanol vapor and the water.
