Description
Technical field
The present invention relates to papermaking making beating energy saving technique, be specifically related to a kind of medium consistency refining energy saver.
Background technology
Making beating is by shearing, rubbing and the distortion action of mechanical force to paper fibre, and fibrocyte primary wall, secondary wall are broken, and makes fiber suction swollen, wire-dividing broom purification then, reaches to meet to manufacture paper with pulp and the characteristic of paper product quality requirement; Beating energy consumption occupies very big ratio in the paper-making pulping, refining pulp quality directly influences into paper product matter, and during making beating is brought up to by low dense (＜4%) dense (8～13%), beating energy consumption can reduce by 20～30%, become the paper physical index to improve 5～10%, obviously reduce the sewage disposal load that making beating produces simultaneously.
Medium consistency refining adopts from the suction mode and advances slurry, and (1480 rev/mins) rotation at a high speed produces centrifugal force slurry is sucked the defibrination district during making beating of mill abrasive disc; Water is made the carrier that pulp fiber flows, and its flow behavior is bigger than pulp fiber, and along with the increased fiber of concentration is woven into nettedly mutually, concentration is high more, and that it is flowed is difficult more, and suction mode is certainly advanced to starch the beating consistency maximum and is no more than 10%; The suction capactity of defibrination abrasive disc is limited, and the flowing velocity of water is more faster than pulp fiber, and slurry concentration exceeds 10% making beating efficient and descends rapidly, and the refining pulp quality instability.
The middle underflow pump pumping mode advances slurry can make beating consistency bring up to 15%, need establish turbulent flow generator before the middle underflow pump pumping slurry makes fiber increase flow behavior, need establish vavuum pump in the pumping process air that slurry rotates generation is at a high speed extracted out, slurry advances need establish the slurry pulse attenuator before the mill and carry out the step-down current stabilization; Middle underflow pump costs an arm and a leg, operates complicated, the height that consumes energy of control, has only minority producer to adopt.
Summary of the invention
For overcoming the shortcoming and defect that prior art exists, the object of the present invention is to provide a kind of medium consistency refining energy saver.
