Description

technical field [0001] The invention relates to the technical field of membrane filtration, in particular to a novel dynamic membrane filtration system. Background technique [0002] Food, medicine, new energy and other industries all involve filtration and separation in the production process, such as wine filtration, traditional Chinese medicine purification, beverage concentration, fermentation filtration, lithium battery slag recovery and other processes require filtration, separation or concentration. At present, organic membrane materials are commonly used in industry for filtration and separation treatment, but commonly used organic membrane modules are basically filtered and separated at room temperature, and cannot be used at high temperatures for a long time. In the actual process, it is necessary to cool down, filter and separate, and then carry out subsequent processes at elevated temperatures, which increases energy consumption. In addition, general filtration ...

At present, organic membrane materials are commonly used in industry for filtration and separation treatment, but commonly used organic membrane modules are basically filtered and separated at room temperature, and cannot be used for a long time at high temperature

In the actual process, it is necessary to cool down, filter and separate, and then carry out subsequent processes at elevated temperatures, which increases energy consumption

In addition, the general filtration and separation device only obtains the product on the permeation side, and there is no filtration and separation device that has a high concentration factor and is not easy to cause contamination of the filter element for the product that needs to be concentrated.

[0003] Ceramic membranes have good mechanical properties and corrosion resistance, but the currently used tubular ceramic membrane modules have limited filtration area and low flux, making it difficult to meet the requirements of industries with large flows such as milk and sugar. In order to increase flux, ceramic membranes should be expanded Chinese utility model patent with authorized announcement number CN208906018U discloses a rotary ceramic membrane filtration and separation device. A rotary ceramic membrane filtration and separation device is proposed in which the ceramic membrane can rotate under working conditions. , to reduce the pollution of the ceramic membrane, and the service life of the ceramic membrane can be extended, but the distributor of the device is fixed on the base of the pressure vessel, and only the ceramic membrane can rotate. As time goes on, the liquid in the pressure vessel will easily form a laminar flow, and the filtration efficiency will decrease. , the ceramic membrane flux decreases

In addition, due to the limited power of the geared motor, the speed of the ceramic membrane can only be adjusted within a certain range, and a wider range of speed regulation cannot be achieved
