Embodiment 1

[0020] The hydrogen purification device includes four metal hydride reactors 3, a flow and pressure control system 6, the metal hydride reactor 3 is filled with AB5 type rare earth hydrogen storage alloy, the inlet is controlled by the valve 2, the front end is connected to the hydrogen source 1, and the outlet It is controlled by a three-way valve 4, and connected with a hydrogen device 7 through a flow and pressure control system 5. The three-way valve 4 can control two directions. When the metal hydride reactor 3 completes the hydrogen absorption, it is first opened to the exhaust 5, and after the impurity gas is discharged, the metal hydride is decomposed to release pure hydrogen, and it is opened to the rear end for supply. hydrogen.

Embodiment 2

[0022] The hydrogen purification device includes four metal hydride reactors 4, a heating system 3, and a flow and pressure control system 7. The metal hydride reactors 4 share a heating system 3, and the metal hydride reactors 4 are filled with magnesium-based hydrogen storage alloys. , the inlet is controlled by valve 2, the front end is connected to hydrogen source 1, the outlet is controlled by three-way valve 5, and the rear is connected to hydrogen equipment 8 through flow and pressure control system 7. The three-way valve 5 can control two directions. When the metal hydride reactor 4 is full of hydrogen, it is first opened to the emptying 6, and after the impurity gas is discharged, it is opened to the rear end to supply hydrogen.

Embodiment 3

[0024] The hydrogen purification device includes two metal hydride reactors 3, a flow and pressure control system 4, the metal hydride reactor 3 is filled with a Ti-Mn hydrogen storage alloy, the inlet is controlled by a valve 2, the front end is connected to a hydrogen source 1, and the outlet It is connected to the flow and pressure control system 4, which is controlled by the three-way solenoid valve 6, and connected to the hydrogen equipment 7. The three-way solenoid valve 6 can control two directions. When the metal hydride purifier 3 is full of hydrogen, it will first open to the emptying 5, and the emptying amount will be fed back through the flow and pressure control system. When it is determined that the specified value is reached, it will turn to the backward direction. End supply hydrogen to meet hydrogen demand.

Abstract

The invention provides a hydrogen purification device. The hydrogen purification device comprises at least two metal hydride reactors and a flow and pressure control system, wherein the at least two metal hydride reactors are filled with hydrogen storage alloys, inlets and outlets are controlled through valves, the inlet ends are connected with a hydrogen source with lower purity, purified hydrogen with higher purity is released from the outlet ends, and the outlet ends are connected to hydrogen utilization equipment through the flow and pressure control system. By means of the hydrogen purification device, hydrogen can be continuously purified, hydrogen with higher purity is output ceaselessly, the output flow and pressure are controlled, and the device is convenient to operate and runs stably.

Description

Technical field [0001] The present invention involves a hydrogen purification device, based on solid -state hydrogen storage technology, realizing the purification and purification of hydrogen, which belongs to the field of storage, purification and supply of hydrogen. Background technique [0002] With the increasing exhaustion of oil energy and the intensification of environmental pollution problems, people have begun to turn their attention to replacement and renewable energy.Hydrogen energy is a clean energy source that countries around the world are actively researching and developing. It has the advantages of high burning thermal value, zero pollution, and rich resources. It has been widely used in all walks of life. [0003] As the requirements of hydrogen in various industries are getting higher and higher, how to further improve the purity of hydrogen has become a problem that the market is urgently needed.At present, the methods of preparation of ultra-high pure hydroge...
