ABSTRACT:
A purifier having a central core in which is disposed a container for gettering material surrounded by electric heaters. Labyrinth passageways for heat exchange between the incoming and outgoing gases is formed by a series of "cans" which are welded in position and have an increasing end plate diameter and shell diameter from the core outwardly. Interspersed shells provide for incoming (outgoing) gas to pass from one end to the opposite end of a cylindrical passage, then turn around the end of the shell and pass in the opposite direction along the next inner (outer) passage. The incoming gas is transferred between passages by holes in alternate end plates, while the outgoing gas is transferred between one passage and the next outer passage by a "floating" end plate, around the inside circle of which the outgoing gas passes.
A second container of gettering material, if desired, operating at a lower temperature can be interposed in the central core, but is insulated from the first container. The outgoing gases, when reduced to the desired temperature for the second gettering material may be passed into and through the second container, then resume transmission through the labyrinth passages.
