Technical Field

[0001] This utility model relates to the technical field of hydrogen recovery, and in particular to a dual-tower hydrogen recovery device. Background Technology

[0002] Hydrogen is used in some chemical production processes, and there is a common problem where hydrogen is not completely used after participating in the reaction. A common solution is a dual-tower hydrogen recovery device disclosed in utility model patent CN211226330U, which mainly consists of a hydrogen compressor, a processing tank, and a recovery tank. During use, the hydrogen is filtered through the processing tank, and then discharged into the recovery tank for storage by the hydrogen compressor, thus completing the hydrogen recovery.

[0003] However, during use, it was found that it was inconvenient to replace the processing tank and the recovery tank during continuous operation of the production line, resulting in poor practicality. Therefore, it is urgent to improve the existing dual-tower hydrogen recovery device to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dual-tower hydrogen recovery device that discharges hydrogen into a processing mechanism to treat impurities and water vapor in the hydrogen, and then discharges the hydrogen into a recovery mechanism for storage. Furthermore, a leak-proof mechanism is used in the hydrogen recovery mechanism to prevent hydrogen leakage, thereby improving the practicality of the equipment.

[0005] This utility model discloses a dual-tower hydrogen recovery device, which includes a support mechanism; it also includes a processing mechanism, a recovery mechanism, and a leak prevention mechanism. The processing mechanism and the recovery mechanism are both installed on the support mechanism, and the leak prevention mechanism is installed on the processing mechanism and the recovery mechanism. The support mechanism supports the processing mechanism and the recycling mechanism. The processing mechanism processes the hydrogen, the recycling mechanism stores the hydrogen, and the leak prevention mechanism prevents hydrogen leakage. Hydrogen gas is discharged into a processing unit to remove impurities and moisture. The hydrogen is then discharged into a recovery unit for storage. In the hydrogen recovery unit, a leak-proof mechanism is used to prevent hydrogen leakage, thereby improving the practicality of the equipment.

[0006] Preferably, the support mechanism includes a base, two sets of rotary tables, multiple sets of guide rails, two sets of gear rings, two sets of drive motors, and two sets of gears. The multiple sets of guide rails are all mounted on the base. The two sets of rotary tables are slidably mounted on the multiple sets of guide rails. The two sets of gear rings are respectively mounted at the bottom center of the two sets of rotary tables. The two sets of drive motors are fixedly mounted on the base. The two sets of gears are respectively mounted on the output shafts of the two sets of drive motors, and the two sets of gears are meshed with the two sets of gear rings. The processing mechanism and the recycling mechanism are respectively mounted on the two sets of rotary tables. By turning on the two sets of drive motors, and through the meshing transmission between the two sets of gears and the two sets of gear rings, the two sets of rotary tables are driven to rotate, thereby adjusting the positions of the processing mechanism and the recycling mechanism, thus improving the practicality of the equipment.

[0007] Preferably, the processing mechanism includes a temporary storage mechanism and multiple processing tanks. The temporary storage mechanism is mounted on a base, and the multiple processing tanks are all mounted on a rotating platform. Each of the multiple processing tanks has an inlet valve at its bottom and an outlet valve at its top. Each of the multiple processing tanks has an impurity filter plate and an adsorption plate inside. The temporary storage mechanism is connected to a set of processing tanks through a leak-proof mechanism. Hydrogen gas flows sequentially through the temporary storage mechanism, the leak-proof mechanism, and the set of processing tanks. Impurities and water vapor in the hydrogen gas are adsorbed by the impurity filter plate and adsorption plate in the processing tanks. After that, the filtered hydrogen gas is discharged into the recovery mechanism, thereby improving the practicality of the equipment.

[0008] Preferably, the recycling mechanism includes a hydrogen compressor, a first conveying pipe, a second conveying pipe, and multiple sets of recycling tanks. The hydrogen compressor is fixedly installed on a base, and the multiple sets of recycling tanks are all fixedly installed on another set of rotating platforms. Each set of recycling tanks is equipped with a sealing valve on its top. One end of the first conveying pipe is connected to the intake port of the hydrogen compressor, and the other end of the first conveying pipe is connected to a set of processing tanks through a leak-proof mechanism. One end of the second conveying pipe is connected to the exhaust port of the hydrogen compressor, and the other end of the second conveying pipe is connected to a set of recycling tanks through a leak-proof mechanism. The first and second conveying pipes are rotatably connected to the two sets of rotating platforms respectively. When the hydrogen compressor is turned on, the filtered hydrogen flows sequentially through the first conveying pipe, the hydrogen compressor, and the second conveying pipe before entering a set of recycling tanks, thereby improving the practicality of the equipment.

[0009] Preferably, the leak-proof mechanism includes multiple sets of cylinders, multiple sets of telescopic tubes, multiple sets of support plates, multiple sets of telescopic tubes, multiple sets of quick connectors, multiple sets of cylinders, and multiple sets of support plates. Multiple sets of cylinders are respectively mounted on the base, the first delivery tube, and the second delivery tube. One end of each set of telescopic tubes is respectively mounted on the temporary storage mechanism, the other end of the first delivery tube, and the other end of the second delivery tube. Multiple sets of support plates are respectively mounted on the other end of each set of telescopic tubes and are connected to each set of cylinders. Multiple sets of telescopic tubes and multiple sets of quick connectors are respectively mounted on the multiple sets of support plates. The equipment consists of multiple quick-connect couplings located within multiple telescopic tubes, each connected to the interior of the first telescopic tube. Multiple support plates are mounted on one end of each telescopic tube, and one end of each cylinder is mounted on the first support plate, with the other end also mounted on the second support plate. The extension of the first cylinder connects the quick-connect couplings to the temporary storage mechanism, processing tank, and recovery tank. The extension of the second cylinder then seals the cylinders, improving the equipment's practicality.

[0010] Preferably, the temporary storage mechanism includes a gas storage cylinder, a piston, and a hydraulic cylinder.

The piston is slidably mounted in the gas storage cylinder, and the hydraulic cylinder is fixedly mounted on the gas storage cylinder, with one end of the hydraulic cylinder mounted on the piston. Hydrogen passes through the gas storage cylinder and then through a quick connector and telescopic pipe below the left rotating platform to enter the processing tank. When changing the processing tank or recovery tank, the connecting valve on the exhaust pipe of the gas storage cylinder is closed, and the piston moves backward by contracting the hydraulic cylinder, drawing hydrogen into the gas storage cylinder. After the processing tank or recovery tank is changed, the connecting valve is reopened, and the temporarily stored hydrogen in the gas storage cylinder is slowly discharged by extending the hydraulic cylinder, thereby improving the practicality of the equipment.

[0011] Preferably, each of the multiple sets of recycling tanks is equipped with a pressure sensor, allowing staff to monitor the pressure within the tanks in a timely manner.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: hydrogen is discharged into the processing mechanism, where impurities and water vapor in the hydrogen are treated, and then the hydrogen is discharged into the recovery mechanism for storage. Furthermore, in the hydrogen recovery mechanism, a leak-proof mechanism is used to prevent hydrogen leakage, thereby improving the practicality of the equipment. Attached Figure Description
