METHOD OF PRODUCING BAG FILTER FILTRATION ELEMENT Russian patent published in 2011 - IPC B01D39/06

Abstract RU 2431518 C1

FIELD: process engineering.

SUBSTANCE: invention relates to filtration. Proposed method comprises producing mullite-siliceous felt is compacted to plate shape to density of 0.7-0.8 g/cm³. Then, filtration element of made and compacted to density of 0.9-1.0 g/cm³. Now, filtration element is saturated with liquid glass or siliceous water solution, blown by air to residual moisture content of 20-30% and heated to 500-1000°C at 50-100°C/h.

EFFECT: higher filter dust retentivity, reduced drag in high-temperature gas filtration.
