DEVICE FOR CLEANING STEAM OR GAS FROM FOREIGN IMPURITIES Russian patent published in 2014 - IPC B01D45/04 

FIELD: process engineering.

SUBSTANCE: invention relates to power engineering and can be used in designing and updating of boiler and turbine equipment operated on high- and medium-pressure two-phase flows (superheated steam-solid particles) and on those of low-pressure (moist steam with fluid drops or films). This device comprises pipeline lower horizontal section with Venturi nozzle accommodated therein to make circular chamber of separation of its outer surface to house louvre stack and blading. Front part of said circular chamber communicates via pipeline with circular inlet diffuser while its mid part communicates with Venturi nozzle diffuser section inlet. Confuser and cylindrical parts of Venturi nozzle are shifted to pipeline top wall to increase inlet diffuser width at bottom section and to decrease its at pipeline top. Differ section of Venturi nozzle is shifted relative to cylindrical section to pipeline bottom wall to make confuser circular section width exceed that at its top. Circular separation chamber is divided into top and bottom parts. Note here that said louvre stack is inclined to pipeline inner surface in one plane while in lateral sectors it is inclined in two planes. Vaned distributor is arranged in separation chamber top part, its vanes being directed to separation chamber bottom louvre stack inlet. Channel for passage of major fragments to accumulator zone is made at louvre stack bottom zone. Circular chamber communicated with said accumulator is arranged at periphery of circular confuser channel.

EFFECT: higher degree of cleaning at minimum power consumption.
