Abstract
Exemplary embodiments provide a pyro gasifyer apparatus and method that may be used in a pyro-gasification system. According to an example embodiment, a loading unit may receive waste and a pyro gasifier unit may receive the waste and convert it into purified syngas through a two-stage process using exhaust gas and a gasifying agent. An engine may receive the purified syngas and generate the exhaust gas, such that a gasifying unit may generate the gasifying agent using energy provided by the exhaust gas. A control unit may monitor and control the amount of the purified syngas, the exhaust gas, and the gasifying agent.
Claims9
A pyro gasifier comprising:
- a first stage connected to a source of waste, the first stage comprising:
- a waste shredder configured to receive the waste and generate shredded waste,
- a rotating screw feeder directly and sequentially connected to the waste shredder, wherein the rotating screw feeder is configured to receive the shredded waste, generate dried shredded waste, and transport the dried shredded waste,
- a rotating drum sequentially connected to the rotating screw and configured to rotate, wherein the rotating drum is configured to receive the dried shredded waste from the rotating screw feeder and generate the fine particulates and the raw syngas, and
- at least one exit port facilitating transfer of the raw syngas out of the first stage, the raw syngas being a gas that escapes out of the at least one exit port;
- and
- a second stage comprising a swirler system, the swirler system comprising:
- a recirculating loop with a compressor configured to circulate the raw syngas and output purified syngas;
- and
- a rotating screw attached to a mechanical seal configured to prevent the circulating syngas from escaping;
- and
- wherein the rotating screw feeder and the rotating drum are both connected to a source of a gasifying agent to facilitate a drying process at the rotating screw feeder and the rotating drum.
