この発明は再生紙料による古紙パルプからインキ類を除
去する脱墨方法とその装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deinking method and apparatus for removing ink from waste paper pulp made from recycled paper stock.
印刷した損紙や裁落しまたは使用済みの廃紙などの古紙
は、製紙原料として木材パルプに次いゼ多く使用され、
極めて重要なものである。Waste paper, such as printed waste paper, bleeds, or used waste paper, is the second most used raw material for papermaking, second only to wood pulp.
It is extremely important.
古紙を回収して白色の紙料に再生する場合、付着してい
るインキ類の分離処理を施した後インキ類をパルプから
除去する脱墨処理を施さなけれはならない。When waste paper is collected and recycled into white stock, it is necessary to perform a process to separate adhering inks and then perform a deinking process to remove the ink from the pulp.
従来の脱墨方法は、インキ類の分離処理を施した古紙パ
ルプ溶液にエヤを混入し−この溶液を分離槽内に下部か
ら供給し、分離杷Ｉ内の溶液中を上昇するエヤによって
気泡を発生させてこの気泡でインキ類を捕捉し、パルプ
溶液上にたまった気泡を掻寄せ装置で除去することによ
り、パイプからインキ類を分離するようにしていた。In the conventional deinking method, air is mixed into a waste paper pulp solution that has been subjected to ink separation treatment, and this solution is fed into a separation tank from the bottom, and air bubbles are removed from the solution by the air rising through the solution in the separation loaf I. The ink was separated from the pipe by generating air bubbles, trapping the ink, and removing the air bubbles accumulated on the pulp solution using a scraping device.
ところで、上記のような脱墨方法は一古紙パルプ溶液に
対して単にエヤを上昇させるだけであるため、エヤとパ
ルプ溶液との接触が少なく、しかもエヤが気泡に成長す
る機会が短かいため、気泡によるインキ類の捕捉が充分
に行なえず、処理能率が極めて悪いという問題がある。By the way, since the deinking method described above simply raises the air in the waste paper pulp solution, there is little contact between the air and the pulp solution, and the opportunity for the air to grow into bubbles is short. There is a problem in that ink cannot be sufficiently captured by air bubbles, resulting in extremely low processing efficiency.
また、エヤは単にパルプ溶液内を上昇するだけであるた
め、発生した気泡が上昇途中で破損し一インキ類の捕捉
効果が極めて悪いと共に、パルプ溶液の分離槽内への挿
入圧力は溶液高さによって生じる液圧よりも高くしなけ
れはならず−このため挿入圧力が高圧になり一圧入装置
を大型強力１Ｇしなければならないので、設備コスト及
び稼動コストが高くつく。In addition, since the air simply rises in the pulp solution, the generated air bubbles break on the way up, making the ink capture effect extremely poor, and the pressure at which the pulp solution is inserted into the separation tank is limited to Therefore, the insertion pressure becomes high, and the press-fitting device must be large and powerful at 1 G, resulting in high equipment and operating costs.
さらに、分離後の気泡を掻寄せ装置によって除去するに
は、パルプ溶液のレベル調整が面倒であると共に一装置
全体が大型化し、広い設備スペースが必要になるという
問題がある。Further, in order to remove air bubbles after separation using a scraping device, there are problems in that it is troublesome to adjust the level of the pulp solution, and the entire device becomes large, requiring a large equipment space.

予じめインキ類の分離処理が施された古紙パルプ溶液ハ
供給管６で遠心分離槽１に送られ、その途中でエジェク
ター７によりエアが混入される。The waste paper pulp solution, which has been subjected to ink separation treatment in advance, is sent to the centrifugal separation tank 1 through a supply pipe 6, and air is mixed in by an ejector 7 along the way.

上部の取出口５から取出管１３を通って処理ｍ１４に流
出する。Air bubbles are generated due to the air being mixed in, and these bubbles capture ink and foreign matter with a light specific gravity, and the vortex generated in the separation tank 1 causes the pulp solution with a heavy specific gravity to be removed, as shown by the two-dot chain line in Fig. 1. A is on the outside, air bubbles 13 with a light specific gravity are separated into gas and liquid in the center, and the air bubbles that have captured ink flow out from the outlet 5 in the upper center through the take-out pipe 13 to the processing m14.
また、パルプ溶液は、旋回動しながら徐々に下降してい
くが、この下降速度よりも早い流速で処理槽１内にパイ
プ溶液が供給されるため、エヤの混入されたパルプ溶液
と旋回流パルプ溶液は接触する。In addition, the pulp solution gradually descends while rotating, but since the pipe solution is supplied into the processing tank 1 at a flow rate faster than this descending speed, the pulp solution mixed with air and the swirling flow pulp The solutions come into contact.
このため、供給パルプ溶液に混入したエヤによって発生
する気泡とパルプ溶液との接触が広範囲にわたって生じ
一気泡の成長が良くなり、気泡によるインキ類の捕捉効
率が大幅に向上する。Therefore, the air bubbles generated by the air mixed in the supplied pulp solution come into contact with the pulp solution over a wide range, and the growth of each bubble is improved, and the efficiency of capturing ink by the air bubbles is greatly improved.
遠心分離槽１内を下降したパルプ溶液は渦流停止板１２
により旋回動が止まり、パルプ取出口１０から円滑に流
出する。The pulp solution descending in the centrifugal separation tank 1 passes through the vortex stop plate 12
As a result, the rotational movement is stopped, and the pulp flows out smoothly from the pulp outlet 10.
また、パルプ溶液の旋回と下降により、中央部の気泡が
下方に引込まれようとするが、下部に気泡阻止板１１が
配置しであるため、気泡がパルプ取出口１０に流出する
ようなことがない。Furthermore, as the pulp solution swirls and descends, the air bubbles in the center tend to be drawn downward, but since the air bubble blocking plate 11 is disposed at the bottom, the air bubbles do not flow out to the pulp outlet 10. do not have.
パルプ取出口１０から流出したインキ類除去後のパルプ
溶液は次の工程に送られ一二次処理槽１４に送られた気
