FACILITY AND METHOD FOR TREATMENT OF BASIC ELONGATED MATERIAL, SUITABLE FOR PAPER MANUFACTURING, FACILITY AND METHOD FOR TREATMENT OF FIBROUS CELLULOSE MATERIAL INTO PAPER PULP, FACILITY AND METHOD FOR TREATMENT OF BLACK LIQUOR, FORMING AT PAPER MANUFACTURING Russian patent published in 2008 - IPC D21B1/00 D21C3/00 

FIELD: textile fabrics, paper.

SUBSTANCE: it is intended for usage in pulp and paper industry. Invention contains processing unit for treatment of fibrous cellulose basic material, containing treatment tool for discharge of inclusion from basic material, grinding tool for basic material crushing for destruction in it nodes and decompose tool for decomposition lengthway of crushed basic material. It is used conveyor with pair of rotated in the same direction screws for treatment of crushed material into paper pulp, at that conveyor is devided into multitude of sections, facility for feeding of materials to be treated at least in one area and facility for temperature control and/or pressure at least in one of areas. Black liquor, formed during the process of paper pulp output, is treated in facility, containing evaporator for concentration of black liquor till containing of solid substance 30-70%, instrument for treatment of concentrated black liquor at temperature 300-650°C and encapsulated conveyor for transportation of concentrated black liquor from evaporator to instrument at temperature higher than 90°C. Invention also includes method, consisting in usage of described above facility.

EFFECT: creation of treatment advantageous process of fibrous cellulose basic material and treatment of black liquor.
