Abstract

The invention provides a solution to the problem of the construction of a filter plate with optimum yield of filtrate starting with the active surface of the membrane for a minimum energy consumption. The apparatus comprises essentially a set of filter plates clamping the membranes. Each plate 1 is in the shape of a lozenge with rounded summits. In the vicinity of the acute-angled summits flow orifices 7 and 8 are arranged, communicating with notched channels 11 which become separated radially and, in step with the distancing, the width of the channel increases and its depth decreases, so that the section of the channel remains constant over its whole length. <IMAGE>

Формула изо бретенияClaim Мембранный аппарат, состоящий из набора мембранных элементов, сжатого болтами между двумя фланцами, в котором каждый мембранный элемент выполнен в виде опорной плиты с двумя коллекторными отверстиями, на одной стороне которой размещены мембрана и дренажная система, а ·.· на другой выполнены проходные каналы, симметрично расходящиеся от одного коллекторного отверстия и сходящиеся к другому, отличающийся тем, что. с целью повышения производительности аппарата за счет снижения влияния концентрацион- ной поляризации, опорные плиты выполнены в виде ромба с закругленными вершинами при острых углах, коллекторные отверстия расположены в остроугольных вершинах ромба, а каждый из проходных каналов выполнен с неизменяемой площадью поперечного сечения по всей его длине, при этом по мере удаления от коллекторных отверстий ширина каналов увеличивается, а глубина уменьшается, кроме того, угол раствора краев каждого канала тем больше, чем канал дальше расположен от более длинной диагонали ромба.Membrane apparatus, consisting of a set of membrane elements, bolted between two flanges, in which each membrane element is made in the form of a base plate with two collector holes, on one side of which the membrane and drainage system are placed, and ·. · Passage channels are made on the other, symmetrically diverging from one collector hole and converging to another, characterized in that. in order to increase the productivity of the apparatus by reducing the influence of concentration polarization, the base plates are made in the form of a rhombus with rounded peaks at sharp angles, the collector holes are located in the acute-angled peaks of the rhombus, and each of the passage channels is made with an unchanged cross-sectional area along its entire length , while the distance from the collector holes the width of the channels increases and the depth decreases, in addition, the angle of the edges of each channel is larger, the further the channel is located wives of the longer diagonal of the rhombus.
