Abstract:
1. An ozone concentrator, comprising: an ozone generator; a plurality of adsorption/desorption columns in which an ozone adsorbent cooled with a certain-temperature refrigerant for concentrating ozone generated by the ozone generator is packed; cooling means for cooling the refrigerant; discharging means connected to the plurality of adsorption/desorption columns, for concentrating the ozone in the plurality of adsorption/desorption columns by discharging a discharge gas comprising mainly oxygen from the adsorbent adsorbing the ozone; and a plurality of valves connected to the adsorption/desorption columns, for switching passages of gas that is allowed to flow in or flow out with respect to the adsorption/desorption columns, wherein said discharging means comprises a discharge line connecting a first adsorption/desorption column to a second adsorption/desorption column and the discharge line obtains the discharge gas from a top portion of the first adsorption/desorption column and passes the discharge gas to a bottom portion of the second adsorption/desorption column, wherein the discharge line is connected on a first end to a top portion of the first adsorption/desorption column and on a second end to a bottom portion of the second adsorption/desorption column.
