The invention belongs to the technical field of garbage
pyrolysis, and particularly relates to a high-temperature
pyrolysis reactor for reducing the dust content of oil gas. The
pyrolysis reactor shell adopts a stepped structure with a small front part and a large rear part, the front end is provided with a reactor material inlet, and the
tail part is provided with a pyrolysis
solid product outlet; and the rear middle portion of the reactor shell is a shell amplification section, a protruding cavity in the upper portion of the amplification section serves as a pyrolysis gas outlet area, a
shutter baffle is arranged at a
gas phase inlet of the area, a
rotational flow device is arranged in the area, a pyrolysis gas outlet is formed in a
gas phase outlet, and the pyrolysis gas outlet is a
rotational flow device outlet. And the
rotational flow device and the pyrolysis gas outlet are arranged above the pyrolysis
solid product outlet. By utilizing the structure of the pyrolysis reactor, the pyrolysis gas is subjected to gas-phase dry-type dust removal in the pyrolysis reactor, so that the dust content of a pyrolysis gas outlet is reduced, the subsequent dust removal
process configuration of the pyrolysis gas is simplified, and the
pyrolysis oil treatment difficulty is reduced.
