US 12,370,489 B2 · Drying device for recycling adsorbent by using microwaves

Abstract

The present invention relates to a drying apparatus capable of regenerating an adsorbent used for drying using microwaves. The drying apparatus of the present invention is formed to include a microwave irradiation means configured to irradiate microwaves to the adsorbent in a plurality of reaction towers in which the adsorbent adsorbing moisture or carbon dioxide is embedded, and when regenerating the adsorbent, directly heats the adsorbent using microwaves, thereby shortening a heating time and securing a sufficient cooling time, resulting in the effect of reducing the amount of dry air consumed for cooling and further increasing the drying efficiency.

Dependent claims

A drying apparatus comprising:

at least one reaction tower in which an adsorbent configured to adsorb moisture or carbon dioxide is embedded;
a pipe connected to the at least one reaction tower and configured to transport air;
valves provided on the pipe and configured to control an air flow;
and
a microwave irradiation portion configured to irradiate microwaves to the adsorbent inside the at least one reaction tower,
wherein the microwave irradiation portion is configured to operate in the at least one reaction tower in which regeneration of the adsorbent is performed,
wherein a hollow portion is formed in the at least one reaction tower and comprises a certain region provided with the microwave irradiation portion, and
wherein the microwave irradiation portion includes a magnetron configured to selectively irradiate microwaves, and a microwave waveguide configured to transmit microwaves to the adsorbent through the hollow portion.
