Description
Известные способы флотации оборотной воды с применением избыточного давлени или разрежени н снециальных химикатов позвол ют улавливать волокно в незначительных количествах.Known methods of circulating water flotation using overpressure or dilution and non-specialized chemicals allow trapping of the fiber in small quantities.
Описываемый способ повышает степень улавливани волокна путем пропуска содержащей волокно воды между электродами, где она насыщаетс пузырьками газа, которые вместе со сцепиви1имис с ними волокнами поднимаютс на поверхность воды, откуда волокна удал ют съемником.The described method improves fiber trapping by passing water containing fiber between electrodes, where it is saturated with gas bubbles, which, together with bonding fibers with them, rise to the surface of the water, from where the fibers are removed with a puller.
На чертеже ириведена схема флотации волокна с номощью частичного электролиза сточной воды бумагоделательной машины и сбора скона.In the drawing, a flotation diagram of the fiber with the help of partial electrolysis of the wastewater of a papermaking machine and collection of the skone is shown.
По массопроводу 1 в электролизер 2 поступает вода, содержаща волокпа. За счет частичного электролиза поступающей воды в электролизере 2 происходит насыщение ловушечной воды пузырьками газов, наход щихс в мелкодисперсном состо нии. этом наблюдаетс эффективное сцепление пузырьков газа с волокнол и флотаци их на иоверхность ловущки, с которой ведетс непрерывный съем скопа съемником 3. Опущенные в отстойную часть ловущки вертикальные перегородки 4 позвол ют сн ть вихревое движение воды, создава тем самым благоири тные услови дл флотации волокна. Дальнейшее движение осветленной воды 5 показано стрелками, а скопление волокон съемником направл етс в отстойник 6.The mass line 1 enters the electrolyzer 2 with water containing fiber. Due to the partial electrolysis of the incoming water in the electrolyzer 2, the trap water is saturated with bubbles of gases in a finely dispersed state. This ensures effective adhesion of gas bubbles to the fiber and float them onto the surface of the trap, with which the osprey is continuously removed by the puller 3. The vertical partitions 4 lowered into the settling part of the trap allow for the removal of the vortex motion of water, thereby creating favorable conditions for flotation of the fiber. Further movement of the clarified water 5 is indicated by arrows, and the accumulation of fibers by the puller is directed to the sump 6.
Описанный способ флотации волокна в отличие от известных позвол ет уловить 90-95% содержашегое в сточной воде бумагоделательной машины волокна без введени в ловущечную воду дополнительные химикатов.The fiber flotation method described above, in contrast to the known ones, makes it possible to catch 90-95% of the fiber contained in the wastewater of a papermaking machine without introducing additional chemicals into the catch water.
