DISCHARGE SYSTEM FOR REMOVAL SOLID SUBSTANCES FROM CHAMBER Russian patent published in 2012 - IPC B01J8/24 

FIELD: process engineering.

SUBSTANCE: invention relates to means for extraction of solid substances from pressurised chamber with fluidized bed with reduced loss of gas and reagents. Proposed discharge system comprises pressurised chamber with fluidised bed, precipitation chambers, discharge lines, primary discharge valves, vent lines, primary vent valves, transverse lines, transverse valves, and primary outlet valves. Note here that said system does not comprises intermediate tank nor filtration element. In compliance with this invention, proposed method allows transfer of solid-gas mix via discharge line from pressurised chamber into precipitation chamber wherein gas is separated from said mix and carried in at least one another precipitation chamber via transverse line. Solids transferred from precipitation chamber, said emptied chamber receives gas from other precipitation chambers in said system.

EFFECT: higher efficiency of discharge, reduced idle time, higher safety.
