AIFILTECH Ceramic Filter Tube Dust Collector - Hot Gas Filtration Unit

The ceramic filter tube dust collector consists of a tube sheet, filter tube bundle, pulse-jet cleaning system, hopper and casing. Hot dust-laden gas enters below the tube sheet; dust is captured on the outer surface of the rigid ceramic fiber tubes while clean gas exits from the tube bore. Pulse jets periodically strip the dust cake into the hopper. Online cleaning, easy leak checking and tube replacement allow direct treatment of gas up to 900 C without gas cooling pre-treatment.

The rigid ceramic fiber tube has a low-density graded porous structure: a fine-fiber high-efficiency surface layer over a coarse-fiber support skeleton. Most dust is retained by the surface cake while the deep layer provides large dust-holding capacity and gentle pressure rise. Pulse jets of 0.4-0.6 MPa compressed air released through blow pipes generate a pressure wave inside each tube that strips the dust cake in one piece without damaging the element.

Applied to hot gas cleaning for calcium carbide furnaces, ferroalloy furnaces, biomass boilers, medical and hazardous waste incinerators, aluminum remelting furnaces and cement kilns. Tube count, casing structure and temperature class are customized per gas volume and operating conditions.
