[0049] When the hydrogen storage alloy is melted in a vacuum induction melting furnace 10, the steps for treating the harmful gases generated by those skilled in the art are as follows:

[0050] Step 1: The generated harmful gases (such as nitrogen oxides, sulfur dioxide, etc.) flow into the purification cylinder 30 through the exhaust pipe 20. At this time, the external water pump will cause the solution (such as sodium hydroxide solution, lime water, etc.) to flow downward through the atomizing nozzle 43. The downward flowing solution will come into contact with the upward flowing harmful gases, thus reacting with the harmful gases and removing some gases (such as acidic gases). During this process, the servo motor 46 will rotate the circular plate 41, the rotating shaft 50 and the stirring rod 51 to ensure that the gas and liquid are fully mixed.

[0051] Step 2: After spraying, the harmful gases will flow with the air through the T-shaped rigid pipe 60 into the activated carbon 64, where they will be adsorbed by the activated carbon 64.
