Abstract:
1. A device for deozonating an ozone-containing gas, the device comprising: a reaction chamber for ozone destruction; a collecting chamber on an upstream side of the reaction chamber; a distribution chamber on a downstream side of the reaction chamber; a heat exchanger having a plurality of juxtaposed plates defining at least one planar preheating passage and, in heat-exchange contact therewith, at least one planar cooling passage, the cooling passage being connected to the distributing chamber and the preheating passage being connected to the collecting chamber; and means including an inlet opening into the planar preheating passage and an outlet opening into the cooling passage for passing ozone-containing gas into the preheating passage and collecting chamber to the reactor chamber where ozone in the gas is destroyed and thence out through the distribution chamber and the cooling passage, whereby incoming gas in the preheating chamber is heated by indirect heat exchange with outgoing gas in the cooling chamber and outgoing gas in the cooling chamber is cooled by incoming gas in the preheating chamber.
