Title:
DEVICE AND PROCESS FOR COMBINED REMOVAL OF DIOXIN AND DUST FROM WASTE GASIFICATION GAS
Document Type and Number:
WIPO Patent Application WO/2021/168760
Kind Code:
A1
Abstract:
A device and process for the combined removal of dioxin and dust from waste gasification gas. A radial bed is sequentially divided from inside to outside into an inner channel (5), a filler area (3) and an outer channel (4), and a cyclone dust collector (6) is provided in the inner channel (5). High-temperature waste gasification gas enters from a material inlet (1) located on a side surface of the cyclone dust collector (6). After dust is removed in the cyclone dust collector (6), a gas phase is discharged from the top of the cyclone dust collector (6), and a solid phase is discharged from the bottom of the cyclone dust collector (6). The discharged gas phase directly enters the filler area (3) without needing to be cooled so as to be catalyzed and undergo secondary dust removal, and dioxin and organic chlorine are degraded under the action of a catalyst. The device is simple in structure, the area occupied is reduced after integrated design, and the process does not generate secondary pollution and is easy to popularize and use.
