Problems solved by technology

However, the use of this static membrane filtration method is likely to lead to adsorption and deposition of colloidal particles and solute macromolecules on the membrane surface or in the membrane pores, resulting in smaller or clogged membrane pores, concentration polarization on the membrane surface and membrane fouling. Lead to a decrease in membrane permeation flux and poor separation performance

Abstract

The invention discloses an eccentric rotating film filtering device which comprises a fixed shell, a rotating sleeve, a motor and a filter cartridge, wherein the rotating sleeve is rotationally arranged on the top of the fixed shell; the motor is used for driving the rotating sleeve to operate; the filter cartridge is positioned in a cavity of the fixed shell; the upper end of the filter cartridge is open, and the filter cartridge is of a hollow structure; multiple filtering holes are formed in the peripheral side wall of the filter cartridge; a film piece of which the outline is matched with the outline of the filter cartridge is fixedly arranged on the peripheral wall of the filter cartridge in a sleeving manner; a liquid inlet facing the opening of the filter cartridge is formed in the top of the fixed shell; a liquid outlet pipe is arranged at the bottom of the fixed shell; two sides of the bottom of the rotating sleeve downwards extend to form two connecting rods; the filter cartridge is hinged to the two connecting rods; and the mass center of the filter cartridge deviates from the center line of the rotating sleeve. According to the device disclosed by the invention, the phenomena of concentration polarization of the film surface and the film pollution can be well avoided, the permeation flux of the film is obviously improved, and the film separation performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of membrane treatment, and in particular relates to an eccentric rotating membrane filtration device. Background technique [0002] Membrane separation technology has become a marginal science integrating polymer, chemical engineering, biology, physics and mathematics, which will have an immeasurable impact on changing the energy structure of the industry, environmental protection and the development of new technologies. Due to the advantages of high separation efficiency, low energy consumption and simple operation, membrane filtration is widely used in the field of solid-liquid separation. Especially as people's awareness of environmental protection gradually strengthens, membrane separation technology is placed with high expectations and is considered to be one of the most promising new technologies in the 21st century. [0003] At present, the traditional membrane separation generally adopts a static fi...
