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 500-1000C at 50-100C/h. ^ EFFECT: higher filter dust retentivity, reduced drag in high-temperature gas filtration. ^ 2 tbl |
