METHOD AND SYSTEM FOR CONTROLLING FEED OF MATERIAL FOR A FLUE GAS CLEANING DEVICE Russian patent published in 2019 - IPC G05D9/12 B01D53/02 

FIELD: manufacturing technology.

SUBSTANCE: method of controlling material feed includes: rapid achievement of the base balanced speed, which is the operating speed of the roller desorber feeder, when the total discharge of the stripper is equal to the total discharge of the adsorber per unit time; rapid achievement of specified speed in accordance with difference between actual average level of material and specified average level of adsorber material, and basic balanced speed; control of roller feeder of stripper for operation at basic balanced speed, if it is detected that amplitude of oscillations of working speed of adsorber roller feeder in preset first time interval is more, than preset amplitude; and control of roller feeder of stripper for operation at preset speed, if it is detected that difference between actual average level of material and specified average level of adsorber material is constantly in specified differential range in specified second time interval.

EFFECT: method can ensure that when the actual level of adsorber material changes suddenly, material feed can be quickly corrected to a relatively balanced state.
