ADSORPTION COLUMN EMPLOYING HIGH-FREQUENCY HEATING

摘要

PROBLEM TO BE SOLVED: To provide an adsorption column employing high-frequency heating capable of regenerating its adsorbent having adsorbed a substance to be adsorbed by heating the same by virtue of an efficient, economical and compact high-frequency heating element caused to heat by a magnetic field generated by a coil.

SOLUTION: The adsorption column employing high-frequency heating comprising a metal container quipped with an inlet port through which a gas comprising a substance to be adsorbed is sent thereinto and an outlet port through which the gas clear of the substance to be adsorbed is discharged therefrom, an insulator cylinder which is disposed in the container and allows the gas to pass therethrough, a filler comprised of an adsorbent and a high frequency heating element with which the insulator cylinder is filled, and a coil disposed inside the container is characterized in that the substance having been adsorbed by the adsorbent is recovered by causing the adsorbent to desorb the same by transferring heat thereto generated by the high-frequency heating element by applying a high frequency voltage thereonto subsequent to the adsorption of the substance to be adsorbed by the adsorbent.
