BAG FILTER FOR GAS CLEANING WITH METAL SLEEVES Russian patent published in 2024 - IPC B01D46/02 

FIELD: various technological processes.

SUBSTANCE: invention relates to the technique of fine cleaning of gases from dust and other fine particles and can be used in metallurgical, coal, mining industries and industry of construction materials, installations for thermal decontamination and recycling of wastes and other fields. Bag filter for gas cleaning consists of a dusty gas chamber and a clean gas chamber, separated by a metal filtering sleeve, and a filter element regeneration system. Metal filter bag is made of wire permeable materials, which are an elastic-porous structure, forming channels with equivalent diameter of 1–3 mcm for the air flow of the gas being cleaned, wherein wire diameter makes 0.12 to 0.25 mm while total thickness of filter element composed by wire helix makes 5 to 10 mm. Filtering sleeves are made of stainless steel; the wire is coated with a catalytically active layer, which is a two-component active layer.

EFFECT: wider range of operating temperatures, higher quality of filtration and longer life of the filter.
