Apparatus for generating ozone

Apparatus for generating ozone comprising:

• an ozone generator (15);
• a device (21) for collecting the ozone generated;
• a device (24) for discharging the ozone;
• characterized by comprising a first system for measuring the ozone concentration comprising:
• a first measuring device (20) of a first ozone concentration;
• a first pressure measuring device (14) of the gas entering said first measuring device (20) of a first ozone concentration to supply a pressure measurement;
• a first flow rate measuring device (12) of the gas entering said first measuring device (20) of the ozone concentration to supply a flow rate measurement;
• a control system (30, 31) of said apparatus;
• said control system (30, 31) calculates a second ozone concentration based on said first ozone concentration, on said pressure measurement and on said flow rate measurement;
• and
• by comprising a second system for measuring the ozone concentration comprising a second measuring device (25) of a third ozone concentration located downstream of said device (24) for discharging the excess ozone;
• said control system (30, 31) compares the value of said third ozone concentration with a preset value and if said value of said third ozone concentration exceeds said preset value it blocks said apparatus.
