Abstract
A solid hazardous waste pyrolysis process and full-set equipment including a pyrolysis box for hazardous waste and intermittent pyrolysis equipment. The equipment includes an outer and rotatable inner barrel; at least one pyrolysis material placement area is formed in the inner barrel; the placement area formed by multiple groups of guide plates circumferentially arranged on the inner wall of the barrel and baffles arranged on the top of plates at the two ends; each group of plates include vertical and sieve plates that are connected. Hazardous waste placed in the pyrolysis box; a box body is placed between the baffles of the pyrolysis material placement areas; after a pyrolysis device is sealed, heat is carried out to start pyrolysis; the box body rotates at the bottom of the inner barrel; and a material is heated, melts and falls onto the reaction medium below, completing pyrolysis of solid hazardous waste.
