Organic polymer waste material disposal device

Abstract

The present invention provides an organic polymer waste material disposal device, which is mainly composed of a flue gas circulation system, a poor-oxygen cycle de-polymerization device, an oil-gas separation system and a waste residue collection system. The poor oxygen cycle de-polymerization device is divided into an inner chamber and an outer chamber, the flue gas circulation system sends low-temperature poor-oxygen gas to the inner chamber for de-polymerization reaction, and sends high-temperature flue gas to the outer chamber for auxiliary heating, which re-enters the flue gas circulation system; when the waste is subjected to poor-oxygen de-polymerization reaction, and has reaction in the inner chamber, the waste respectively enters the oil-gas separation system, and the waste residue collection system, thus producing the efficient separation of oil, gas and residue.
