Problems solved by technology

[0003] In the prior art, one separation device can provide one-precision filtration. When multiple precision filtrates are required, multiple separation devices are required to achieve this. Therefore, the existing technical solutions cannot meet the requirements of obtaining filtrates on the same equipment. Multiple products with different filter fineness

Abstract

The invention relates to an integrated membrane separation and filtration method and device. The device includes: a power supply, a storage tank, a metering pump, a precision mechanical filter, a microfiltration filter, an ultrafiltration filter and a nanofiltration filter. Specifically, the power supply is connected to the metering pump; a discharge port of the storage tank is communicated with the inlet of the metering pump through a pipeline; the outlet of the metering pump is communicated with the inlets of the precision mechanical filter, the microfiltration filter, the ultrafiltration filter and the nanofiltration filter respectively through a pipeline, and the pipelines between the metering pump and the precision mechanical filter, the microfiltration filter, the ultrafiltration filter and the nanofiltration filter are respectively equipped with a filtration inlet valve; the precision mechanical filter, the microfiltration filter, the ultrafiltration filter and the nanofiltration filter are all equipped with a filtrate discharge pipeline; and the filtration precision of the precision mechanical filter, the microfiltration filter, the ultrafiltration filter and the nanofiltration filter decreases successively. The technical scheme adopted by the invention can realize acquisition of a plurality of liquid products of different filtration precision on the same equipment.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to an integrated membrane separation and filtration method and device. Background technique [0002] Membrane separation technology is an emerging high-tech technology, and it is also a multidisciplinary science and technology.
