Description

Technical Field

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

[0002] In the process of recovering hydrogen, the hydrogen needs to be washed with water. This is generally done through a hydrogen recovery water washing device disclosed in utility model patent CN205313081U and an anti-static device and hydrogen water washing tower disclosed in utility model patent CN202785636U.

[0003] However, during use, it was found that the existing water washing equipment has a relatively simple structure, poor water washing effect on hydrogen, and when changing to pure water, hydrogen recovery needs to be stopped, which affects the operation of the upstream production line, resulting in poor practicality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a hydrogen recovery and washing device that discharges hydrogen into a water washing mechanism through a dispersion mechanism, thereby increasing the contact area between hydrogen and water and thus improving the water washing effect of hydrogen. Furthermore, when the water in the water washing mechanism is replaced, the hydrogen discharged into the water washing mechanism is temporarily stored through a storage mechanism to ensure the stable operation of the upstream production line, thereby improving the practicality of the equipment.

[0005] This utility model discloses a hydrogen recovery water washing device, which includes a water washing mechanism; it also includes a dispersion mechanism and a storage mechanism. The dispersion mechanism is installed in the water washing mechanism, and the storage mechanism is installed on the water washing mechanism.

[0006] The water washing mechanism washes the hydrogen gas, the dispersion mechanism disperses the hydrogen gas, and the storage mechanism temporarily stores the hydrogen gas.

[0007] Hydrogen is discharged into the water washing mechanism through a dispersion mechanism, which increases the contact area between hydrogen and water, thereby improving the water washing effect of hydrogen. When the water in the water washing mechanism is replaced, the hydrogen discharged into the water washing mechanism is temporarily stored through a storage mechanism to ensure the stable operation of the upstream production line, thereby improving the practicality of the equipment.

[0008] Preferably, the washing mechanism includes a washing tank, a dehumidification tank, a baffle plate, and an exhaust valve. The dehumidification tank is installed on top of the washing tank, the baffle plate is installed inside the dehumidification tank, and the exhaust valve is installed on top of the dehumidification tank. The dehumidification tank and the washing tank are connected internally. A drain valve is provided at the bottom rear end of the washing tank. Pure water is discharged into the washing tank. The exhaust valve is connected to the hydrogen pipeline. Then, the dispersion mechanism disperses the hydrogen into the pure water in the washing tank, allowing the pure water to wash the hydrogen and remove impurities. The hydrogen then rises and enters the dehumidification tank, where it is dehumidified by the baffle plate. After dehumidification, the hydrogen passes through the exhaust valve and enters the hydrogen pipeline, thereby improving the practicality of the equipment.

[0009] Preferably, the dispersion mechanism includes a conveying pipe, a one-way valve, a flow guide, a jet pipe, multiple sets of nozzles, a drive motor, gears, and a gear ring. One end of the conveying pipe is installed at the bottom of the washing tank, and the other end extends into the storage mechanism. A connecting valve is provided on the conveying pipe. The one-way valve and the flow guide are both installed on the other end of the conveying pipe. The jet pipe is rotatably installed at the bottom of the washing tank, with its top extending into the interior of the conveying pipe and its bottom extending below the washing tank and rotatably connected to one end of the conveying pipe. Multiple sets of nozzles are installed at the top of the jet pipe. The drive motor is fixedly installed at the bottom of the washing tank. The gear is installed on the output shaft of the drive motor. The gear ring is fitted onto the bottom of the jet pipe, and the gear ring and gear are meshed. Hydrogen gas passing through the storage mechanism flows sequentially through the one-way valve, the conveying pipe, and the jet pipe, and then is sprayed out through multiple sets of nozzles. At the same time, the drive motor is turned on, and the gear and gear ring mesh to drive the jet pipe to rotate, so that the multiple sets of nozzles evenly spray hydrogen gas into the pure water in the washing tank, thereby improving the practicality of the equipment.

[0010] Preferably, the storage mechanism includes a frame, a cylinder, a base, an air bladder, a lifting platform, an intake valve, an atomizing mechanism, and a draining mechanism. The air bladder is mounted on the base, and the lifting platform is mounted on top of the air bladder, with the lifting platform slidably connected to the frame. The cylinder is mounted on the frame, with its bottom mounted on top of the lifting platform. The intake valve is mounted on top of the lifting platform, and both the atomizing mechanism and the draining mechanism are mounted on the lifting platform. The intake valve is connected to an exhaust pipe, allowing hydrogen gas to be discharged into the air bladder through the intake valve. Simultaneously, the atomizing mechanism atomizes pure water and discharges it into the air bladder. Atomized pure water pre-cleans the hydrogen gas, which then passes through a one-way valve into the delivery pipe. Before replacing the pure water in the washing tank, the cylinder slowly extends to release the hydrogen gas from the air bladder into the delivery pipe, causing the air bladder to contract. Then, the connecting valve on the delivery pipe is closed, and the pure water in the washing tank is replaced. At the same time, the cylinder slowly contracts, allowing the slowly expanding air bladder to temporarily store the unwashed hydrogen gas. After the pure water in the washing tank is replaced, the connecting valve on the delivery pipe is opened to resume operation of the equipment, thereby improving the practicality of the equipment.

[0011] Preferably, the atomizing mechanism includes a water tank, a delivery pump, an annular pipe, and multiple sets of atomizing nozzles. The water tank and the delivery pump are both installed on the washing tank, the annular pipe is installed on the top of the lifting platform, and the multiple sets of atomizing nozzles are all installed on the lifting platform, with the bottom of each set of atomizing nozzles extending below the lifting platform. The drain outlet of the delivery pump is connected to the annular pipe via a flexible hose. Pure water is poured into the water tank, and the delivery pump discharges the pure water into the lifting platform, causing the multiple sets of atomizing nozzles to atomize the pure water and spray it into the airbag, thereby improving the practicality of the equipment.

[0012] Preferably, the sewage discharge mechanism includes a suction pipe, an electrically controlled valve, and a sewage discharge valve. The suction pipe is installed on the washing tank, with one end extending to the bottom of the washing tank. The electrically controlled valve is installed on the other end of the suction pipe and is connected to the lifting platform via a flexible hose. The sewage discharge valve is installed at the bottom of the base. After the cylinder extends to discharge hydrogen from the airbag into the delivery pipe, the electrically controlled valve is opened. The cylinder then contracts, causing the suction pipe to discharge pure water from the washing tank into the airbag to flush its interior. Hydrogen is then continuously supplied to the airbag through the air inlet valve, and the connecting valve on the base is closed. The sewage discharge valve is then opened to drain the sewage from the airbag, and finally, the sewage discharge valve is closed to keep the equipment running, thereby improving its practicality.

[0013] Preferably, the airbag has a steel wire ring inside; this ensures the strength of the airbag and improves the stability of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the hydrogen is discharged into the water washing mechanism through the dispersion mechanism, which increases the contact area between hydrogen and water, thereby improving the water washing effect of hydrogen. Furthermore, when the water in the water washing mechanism is replaced, the hydrogen discharged into the water washing mechanism is temporarily stored through the storage mechanism, ensuring the stable operation of the upstream production line and thus improving the practicality of the equipment.
