Title:
ELECTROSTATIC DUST COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/258522
Kind Code:
A1
Abstract:
An electrostatic dust collection device (1), comprising a frame (10) and a plurality of electrode units (20). The plurality of electrode units (20) comprise high potential units (30) and low potential units (40), wherein dust collection air channels are formed between adjacent electrode units (20). Each high potential unit (30) comprises a first conductive part (210) and a first insulating part (250), wherein the first conductive part (210) comprises a first electric field generating body (211) and a first conductive end (212), with the first insulating part (250) covering the first electric field generating body (211). Each low potential unit (40) comprises a second conductive part (220) and a second insulating part (260), wherein the second conductive part (220) comprises a second electric field generating body (221) and a second conductive end (222), with the second insulating part (260) covering the second electric field generating body (221). The area of the first electric field generating body (211) covered by the first insulating part (250) is larger than the area of the second electric field generating body (221) covered by the second insulating part (260).
