Abstract
Provided is an ozone concentrator including an ozone generator (), adsorption/desorption columns () in which silica gel () cooled with a certain-temperature refrigerant () for concentrating ozone generated by the ozone generator () is packed, a refrigerating machine () for cooling the refrigerant (), a vacuum pump () for enhancing a concentration of the ozone in one of the adsorption/desorption columns () by discharging mainly oxygen from the silica gel () adsorbing the ozone, a plurality of valves () to () for air pressure operations, for switching passages of gas that is allowed to flow in or flow out with respect to the adsorption/desorption columns (), and ozone concentration meters () for measuring the concentration of the ozone enhanced by the vacuum pump (), in which a discharge line of the vacuum pump () is connected to another one of the adsorption/desorption columns (), whereby the ozone is allowed to pass through another one of the adsorption/desorption columns again. Therefore, stable ozone of high concentration can be generated at a satisfactory energy efficiency without any temperature difference between upper and lower positions of adsorption/desorption columns.
