Abstract
An ozone storage system which allows energy required for producing and storing ozone to be reduced and which supplies ozone as stored to an ozone consumer stably in continuation. The system includes an ozone generator (1) for generating an ozonized oxygen gas from an oxygen containing gas by using electric energy, an adsorption/desorption tower (4) including an adsorbent for adsorbing ozone from the ozonized oxygen gas and desorbing apparatus for desorbing ozone from the adsorbent, a circulation pipe (L1) for feeding back the oxygen containing gas to the ozone generator after adsorption of ozone in the tower, an ozone discharging apparatus (11) for discharging ozone desorbed from the tower, an ozone concentration controlling apparatus (14) for adjusting an amount of ozone extracted through the ozone discharging apparatus to thereby supply an ozone containing gas containing ozone substantially at a predetermined constant concentration to an ozone consumer (15), and a low-temperature processing unit (20) for separating oxygen from air to feed an oxygen gas to the ozone generator (1).
