DEVICE FOR CLEANING WASTE GASES CONTAINING ORGANIC AGENTS (VERSIONS) Russian patent published in 2007 - IPC B01D53/86 B01D53/72 B01J8/02 

FIELD: devices for cleaning waste gases from mineral dust and decontaminating the organic component of waste gases; electrode, mining, by-product coke, chemical, oil, oil refining industries and metallurgy.

SUBSTANCE: proposed device consists of decontamination and cleaning unit arranged in heat-insulated housing 1 dividing inner cavity of housing into contaminated gas chamber, working chamber and cleaned gas chamber; it is provided with burner 2 equipped with gas duct 4 for delivery of natural gas; it is communicated with contaminated gas chamber. Decontamination and cleaning unit consists of row of shelves with catalyst cassettes 11. Contaminated gas chamber is provided with branch pipe 5 for delivery of contaminated gas. Cleaned gas chamber is provided with gas duct 7 for discharge of cleaned gas. End faces of shelves are rigidly interconnected in turn by means of blind partitions 10, thus forming meander-type structure. Catalyst cassettes 11 are made from artificial mullite-containing fiber material. Shelves are made in form of lattice 9 and are directed in way of gas flow. Provision is also made for assembly of two devices rigidly interconnected by means of common wall of heat-insulated housing and communicated through transportation gas main.

EFFECT: enhanced ecological safety; facilitated procedure of scheduled maintenance; increased productivity; continuity of process.
