Устройство и способ удаления печатной краски волокнистой массы макулатуры с помощью процесса пенной флотации для рециклирования печатной макулатуры для производства новой бумаги. Печатную бумажную пульпу подают в виде суспензии во впускное отверстие неглубокого резервуара. Внутренние направляющие стенки в резервуаре устанавливают траекторию потока от впускного отверстия до выпускного отверстия. Стенки имеют такие размеры и расположение, чтобы создавать поток, по существу, равномерной площади поперечного сечения. Множество модулей расположены вдоль траектории потока. Каждый модуль включает в себя по меньшей мере один инжектор, который аэрирует поток, и экстрактор, который удаляет плавающую пену печатной краски. Часть потока из каждого модуля рециркулирует в модуль, расположенный вверх по технологической цепочке, предпочтительно с помощью трубы и связанного с ней насоса. В предпочтительном виде только инжектор (или инжекторы), расположенный у впускного отверстия, загружается с помощью следующего вниз по технологической цепочке модуля, и только экстрактор располагается вблизи выпускного отверстия. Изобретение также включает в себя основную петлю рециркулирования от нижнего конца по технологической цепочке траектории потока до верхнего конца по технологической цепочке. Эта основная петля рециркулирования имеет большую скорость потока по сравнению со скоростью потока рециркулирования между модулями.Device and method for removing printing ink from waste paper pulp using a froth flotation process for recycling printed waste paper to produce new paper. Printed paper pulp is fed as a slurry into the inlet of a shallow tank. The internal guiding walls in the tank establish the flow path from the inlet to the outlet. The walls are sized and positioned to create a flow of a substantially uniform cross-sectional area. Many modules are located along the flow path. Each module includes at least one injector that aerates the flow, and an extractor that removes the floating ink of the printing ink. A portion of the flow from each module is recycled to a module upstream through the process chain, preferably using a pipe and a pump connected to it. In the preferred form, only the injector (or injectors) located at the inlet port is loaded using a module downstream of the processing chain, and only the extractor is located near the outlet port. The invention also includes a main recycle loop from the lower end of the flow path to the upper end of the flow path. This main recycle loop has a higher flow rate than the recycle rate between the modules.
