In the utility model, there is standardized design, low power consumption and small floor area; and it integrates helium recovery, on-line purification and cyclic gas supply, with little dependence on and impact on the production line; at the same time, it has a high degree of intelligence and realizes unattended operation all day long.

Moreover, different temperatures will also affect the speed and purity of helium purification. Therefore, a helium recovery and purification equipment is proposed for the above problems.
