Abstract

The invention relates to the field of assembly and cleaning of filter membranes, and discloses a filter membrane assembly system. The filter membrane assembly system comprises a filter membrane assembly chamber, a feeding fluid distribution chamber, a filtered cleaning fluid collecting chamber, a self-cleaning fluid recovery tank and a special cleaning fluid storage tank; the filter membrane assembly chamber comprises at least two membrane module cavities which are isolated from each other; a filter membrane group is arranged in each membrane assembly cavity; an outlet of the feeding fluid distribution chamber is correspondingly connected with inlets of the membrane assembly cavities through first pipelines; an inlet of the filtered cleaning fluid collecting chamber is correspondingly connected with outlets of the filtering membrane groups in the membrane assembly cavities through second pipelines; each first pipeline is connected to the self-cleaning fluid recovery tank through a three-way control valve, and each second pipeline is connected with the special cleaning fluid storage tank through a three-way control valve; and each second pipeline is further provided with a pressuredetection device. The invention further provides a self-cleaning method. According to the invention, the utilization rate of filter membranes can be effectively improved, and the service period of thefilter membranes can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of filter membrane assembly and cleaning, in particular to a filter membrane assembly system and a self-cleaning method. Background technique [0002] Membrane filtration technology has been widely used in seawater purification, sewage treatment, gas separation and petrochemical raw materials, product separation and purification and other fields. Compared with cyclone separation, membrane filtration technology can achieve liquid-solid and gas-solid separation with a particle diameter of less than 5 μm, and even has a better separation effect on nano-scale powders; compared with electrostatic precipitator technology, inorganic membrane filtration materials can be applied When the temperature is as high as 800°C, the electrostatic precipitator technology has a high degree of severity on the temperature (less than 150°C) and the specific resistance of the dust. [0003] Membrane filtration separation technolog...
