Description of the Related Art Conventionally, an adsorber for adsorbing and removing impurity components has been used as a means for removing impurities in various liquids and gases. For example, a helium liquefier refrigerator has a helium refrigerant. Oxygen mixed in with a compressor,
An adsorber is provided to remove impurities such as nitrogen, hydrogen and hydrocarbons. In such an adsorber, when the filled adsorbent is saturated with the adsorbed impurities, the adsorbent is heated to remove the impurities so that the adsorbent can be regenerated and reused.

When nitrogen gas is used as the heating gas, the nitrogen gas used for regeneration may remain in the adsorbent and contaminate the helium refrigerant. Moreover, when helium is used as the heating gas, a large amount of expensive helium is consumed. Furthermore, in order to reuse the helium used as the heating gas, equipment such as a blower must be provided, which increases the cost of the device.

It can be arbitrarily set within a range that does not significantly affect the filling of the adsorbent. Heat transfer member 9 shown in this embodiment
Is a flat plate having a width corresponding to the radius of the container 2 and is alternately installed on the meridian in the vertical direction. However, only one plate may be installed, and the plate may be projected in a direction displaced from the center of the container. Good. Further, the flat plate may be provided with fins to increase the surface area or may be bent appropriately. For example, as shown in FIG. 3, both ends of the heat transfer member 10 made of a plate material bent in an L shape are connected to the container 2 It may be fixed to the inner wall of the. Particularly, in the case of the L-shaped heat transfer member 10 shown in FIG. 3, there is also an effect that the thermal stress due to the temperature distribution of the heat transfer member 10 can be removed.
