製紙原料処理装置
Document Type and Number:
Japanese Patent JP5307400
Kind Code:
B2
Abstract:
Object to attain: To offer a papermaking raw material processor capable of reforming pulp in papermaking process, thanks to cavitation. Means to solve the problem: First pump 5 jets jet liquid and second pump 6 jets suspension containing e.g. pulp fibers into a processing unit inside which cavitation is generated by generation of a jet stream. Inside processing unit 2, a jet stream generates cavitation to carry out a reforming processing in which ink or the like is removed from the fibers by a blast resulting from collapse of cavitation bubbles generated there. The liquid after reforming processing is returned to second tank 4, except for a part of it fed to downstream steps, while the suspension is processed, as circulated between processing unit 2 and second tank 6.
