METHOD OF GAS FLOW CLEANING AND DEVICE TO THIS END Russian patent published in 2015 - IPC B01D47/05 

FIELD: process engineering.

SUBSTANCE: invention relates to separation of disperse particles from gas flow and can be used in gas, oil and petrochemical industries, etc. Proposed device comprises tubular case with inlet channel, several condensation sections each being provided with steam injection means, refrigerator and annular condensate collector and purified gas outlet channel. Every condensation chamber comprises extra refrigerator. Steam blowing means in at least one, preferably, every section is composed of hollow cylinder arranged with radial clearance coaxially with tubular case and composed of two cylindrical shells, inner and outer, arranged with radial clearance relative to each other to make the steam feed inner channels. Every cylinder is composed of two cylindrical shells, inner and outer, arranged with radial clearance relative to each other to make the steam feed inner channels between shells. Cavity of every said steam blow-in cylinder is connected with steam source while extra refrigerator cylinder cavity arranged inside the latter is connected with refrigerator cavity. Rings of steam blow-in means cylinders are provided with holes connecting steam feed channels with circular channels composed by aforesaid cylinders.

EFFECT: higher efficiency of cleaning.
