METHOD OF CONTROLLING DUST BAG FILTER REGENERATION WITH PULSE-TO-PULSE INTERVAL CORRECTION Russian patent published in 2012 - IPC B01D46/02 B01D46/46 

FIELD: process engineering.

SUBSTANCE: invention relates to dry cleaning of gases in electrolysis, namely, to bag filter regeneration control system. Proposed method comprises feeding dusty gas into bag filter, regenerating the latter by compressed air blowing and measuring pressure upstream and downstream of bag filter module, gas dust content upstream of filter and filtration rate. Time interval between regenerations of bag filter is set subject to pressure difference upstream and downstream of aforesaid module and gas dust content upstream of filter. Note here that maximum and minimum time intervals between filter regeneration pulses and maximum and minimum pressure difference are set. Maximum and minimum time intervals between filter regeneration pulses are set for maximum and minimum pressure difference magnitudes. For intermediate pressure difference, time interval between pulses is set in proportion to pressure difference.

EFFECT: improved gas cleaning.
