Description

Technical Field

[0001] The utility model relates to the technical field of recycling equipment, in particular to a device for recycling hydrogen storage alloy powder when dismantling a solid hydrogen storage tank. Background Art

[0002] At present, there are several ways to recycle failed solid hydrogen storage tanks:

[0003] 1. After the failed solid hydrogen storage tank has released all the hydrogen, connect a vacuum pump to draw a vacuum for a certain period of time, then disassemble the pressure reducing valve, and directly pick up the hydrogen storage tank by hand to shake out the hydrogen storage alloy inside. The disadvantages are: since the solid hydrogen storage material will pulverize and expand when absorbing hydrogen, there will be a small amount of hysteresis residue on the hydrogen adsorption of the solid hydrogen storage material, and the vacuum cannot be completely drawn out. When the solid hydrogen storage material is dumped, there is a risk of fire, deflagration, and burns when it comes into contact with air. The personal operation is not safe enough. At the same time, the burned hydrogen storage tank cannot be recycled and used directly;

[0004] 2. After the failed solid hydrogen storage tank has released all the hydrogen, connect the vacuum pump to draw the vacuum for a certain period of time, then disassemble the pressure reducing valve, and use pliers to clamp the hydrogen storage tank to shake out the hydrogen storage alloy inside. The disadvantage is that it is heavy and inconvenient to operate.

[0005] 3. After the failed solid-state hydrogen storage tank has released all the hydrogen, it is placed in a stainless steel vacuum glove box to evacuate the air. By putting on vacuum gloves, the pressure reducing valve is disassembled, and the hydrogen storage tank is picked up to shake out the hydrogen storage alloy inside. The disadvantages are: the stainless steel vacuum glove box is expensive, inconvenient to operate in a limited space, and inefficient. Utility Model Content
