Description
Известные способы фильтрации через трубчатый металло-керамический фильтрующий элемент основаны на принципе образовани осадка на фильтрующей поверхности, что создает главную составл ющую часть сопротивлени фильтрации, требует систематического удалени осадка с фильтрующей поверхности (отдувка и др.) и это в конечном счете отрицательно сказываетс на производительности фильтров.The known methods of filtration through a tubular metal-ceramic filter element are based on the principle of sediment formation on the filtering surface, which creates the main component of filtration resistance, requires systematic removal of sediment from the filtering surface (stripping, etc.) filters.
Описываемый способ основан на принципе фильтрации без образовани сло осадка на фильтрующей поверхности и дает возможность устращ1ть указанные недостатки известных способов. Сущность STOio способа состоит в том, что пульпу подают по кольцевому пространству непрерывным потоком вдоль фильтрующего элемента под избыточным давлением со скоростью не менее 0,5 м/сек.The described method is based on the principle of filtration without forming a layer of sediment on the filtering surface and makes it possible to eliminate these drawbacks of the known methods. The essence of the STOio method is that the pulp is fed through the annular space in a continuous stream along the filter element under excess pressure at a speed of at least 0.5 m / s.
По мере прохождени пульпы в аппарате она сгущаетс ; конечный сгущенный продукт под давлением выходит из аппарата с концентрацией , соответствующей отношению Ж: Т около 0,5-0,8, как это наблюдаетс при работе-гидроциклонов.As the pulp passes through the apparatus, it thickens; the final condensed product under pressure leaves the apparatus with a concentration corresponding to an L: T ratio of about 0.5-0.8, as observed during operation of hydrocyclones.
Применение описываемого способа может оказатьс особо целесообразным в тех случа х, когда перед фильтрацией пульпа находитс под большим давлением.The application of the described method can be particularly useful in cases where the pulp is under high pressure before filtration.
Модель фильтра испытывалась на опытном заводе и показала положительные качества.The filter model was tested at a pilot plant and showed positive qualities.
