Title:
LOW-TEMPERATURE TREATMENT METHOD FOR HOUSEHOLD WASTES
Document Type and Number:
WIPO Patent Application WO/2017/177883
Kind Code:
A1
Abstract:
Disclosed is a low-temperature treatment method for household wastes. The method comprises the following steps: adding household wastes into a pyrolysis container, dewatering the household wastes in the pyrolysis container, carrying out low-temperature pyrolysis on the dewatered household wastes to generate semicoked and sol-like gaseous pollutants, the generated pollutants are semicoked, waste residues are discharged from the bottom of the pyrolysis container, heat generated in the semicoking process is absorbed and stored by the walls and the bottom of the pyrolysis container, and energy for dewatering and pyrolysis is provided by a first heat source (240) and a second heat source (250), the steps are repeated, and the required heat source is provided by the second heat source. Low-temperature pyrolysis and a heat storage material are used to store heat generated during the pyrolysis of wastes, and the low-temperature pyrolysis and the heat storage material are used to continuously treat new wastes, and the continuous pyrolysis of the wastes can be implemented without adding outside energy. In addition, by combining an electrical tar precipitator with a corona plasma air-purification technology, secondary pollutants generated in the pyrolysis are treated, so that smoke-free and odor-free direct charging of the household wastes is implemented.
