Online regeneration device applied to helium circulation

The utility model relates to an on-line regeneration device applied to helium circulation, which comprises a two-layer container with an outer shell and an inner container, a liquid nitrogen interlayer is arranged between the outer shell and the inner container, an adsorbent is arranged in the inner container, a liquid nitrogen inlet pipe and a helium inlet pipe are arranged at the top of the container, the liquid nitrogen inlet pipe is communicated with the liquid nitrogen interlayer, and the helium inlet pipe is communicated with the helium inlet pipe. A liquid nitrogen interlayer is arranged in the container, a heat exchanger is installed on the upper portion of the liquid nitrogen interlayer, the helium inlet pipe is communicated with the bottom of the inner container through a tube pass of the heat exchanger, a helium outlet pipe is arranged on the top of the inner container, and the helium outlet pipe is communicated with the outside of the container through a shell pass of the heat exchanger.
