Problems solved by technology

Both of them generate vibration in a single direction on the filter membrane through a single vibration method, which can achieve the effect of inhibiting the fouling of the filter membrane to a certain extent. In order to ensure that the filter membrane has a low cleaning frequency, the water quality of its influent Strict requirements are required. For example, in the case of large particles or small and easily adhered particles, a single vibration method cannot achieve a significant reduction in cleaning frequency

Abstract

A fractionated salt high-frequency concentrated water treatment system, at least including at least one compartment defined by a filter membrane and a first housing for concentrating or desalinating influent water, based on the influent flow rate and / or When the discharge flow is increased or decreased so that a pressure difference is formed along the flow direction of the incoming water, the first region and the second region can at least rotate around their respective hinge points based on the pressure difference to increase The distance between the filter membranes is increased or decreased so that the filter membranes are arranged obliquely in the second housing, wherein the incoming water flushes the oblique filter membranes in a turbulent manner based on the pressure difference to inhibit scaling. The invention can make the filter membrane assume an inclined state based on the effect of pressure difference, cooperate with the turbulent flow generated in the compartment, and can wash the surface of the filter membrane to effectively inhibit the fouling of the filter membrane.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a high-frequency concentrated water treatment system for fractionated salt. Background technique [0002] Vibrating membrane filtration generates high shear force on the surface of the filter membrane through mechanical high-frequency vibration, which can effectively solve the problems of membrane performance changes such as membrane fouling and clogging in the current static membrane separation technology, greatly increase the filtration efficiency and reduce the cleaning cycle of the membrane. , to prolong the service life of the membrane. The vibration of the filter membrane is often realized based on a mechanical device, an ultrasonic device or an overfrequency device, and the generated vibration form is usually in a two-dimensional state. For example, for a flat filter membrane, a single two-dimensional vibration can be generated by a mechanical device i...
