DEVICE FOR WASHING AND DEHYDRATION OF FIBROUS MASS， CONTROL SYSTEM OF SUCH APPARATUS AND METHOD OF PROCESSING FIBROUS MASS IN SUCH APPARATUS

FIELD: machine building. SUBSTANCE: method of processing fibrous mass in apparatus for flushing and dehydration of pulp and control system of such apparatus， comprising two rotating squeezing rolls (102， 104) with permeable outer surface (106， 108) and bath (114， 116， 118)， in which are installed squeezing shafts (102， 104)， between which squeezed zone (112) is formed. Processing is determined by a set of variable operating parameters which are controlled and/or maintained during operation in response to deviations of measured values of controlled parameters from their corresponding predetermined threshold values. Variable operating parameters include the speed of the squeezing rollers. Adjustable parameters include pressure in bath and/or linear load. EFFECT: disclosed are apparatus for flushing and dehydration of fibrous mass， control system of such apparatus and method of treating fibrous mass in such apparatus. 23 cl， 6 dwg
