Flameless catalytic thermal oxidation device

A cartridge for a thermal oxidation device as a replaceable cartridge included in the thermal oxidation device for treating a material to be treated, the cartridge comprising:

• a chamber-type body;
• a heater provided in the chamber-type body;
• a catalyst support bottom portion which supports a catalyst to fill the catalyst around the heater;
• an inlet into which the material to be treated is introduced;
• an outlet formed in the chamber-type body;
• and
• an impact member connected to the catalyst support bottom portion, wherein the catalyst support bottom portion is provided with a space from a cartridge bottom portion and has an opening through which the material to be treated may be introduced, the inlet starts from an upper part of the chamber-type body and extends to pass through the catalyst support bottom portion, and the material to be treated descends along the inlet to reach a space below the catalyst support bottom portion and then ascends through the opening of the catalyst support bottom portion, and is heated with the catalyst by the heater to be oxidized and then discharged through the outlet,
• the impact member is a hollow tube member, and includes a bead or beads therein and an impact unit of applying the impact to the bead or beads, and a powder present in the cartridge is dropped by movement of the bead or beads, and
• the impact unit is a hydraulic type to apply momentum to the bead or beads by using gas pressure.
