Embodiment Construction

[0014] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0015] The present invention describes a vortex tube membrane module and system. The membrane module is composed of a vortex tube membrane element, a pipe and a casing, and is driven by a motor to rotate. The vortex tube membrane element is shaped For the vortex, spiral and tower spiral structure. The original solution flows inside the tube, and the permeate flows outside the tube.

[0016] The diameter of the vortex tubular membrane element is gradually changing, that is, the membrane passing conditions (pressure, tangential force, etc.) change with the change of the medium characteristic (concentration, viscosity, flow) parameters of the fluid.

[0017] When the flow channel of the vortex tub...

Abstract

The invention discloses a vortex tube-type membrane component and a system. The vortex tube-type membrane component is composed of a vortex tube-type membrane element, a pipeline, and a housing, and is driven by a motor to rotate; and the vortex tube-type membrane element is a structure shaping like a vortex, a spiral, or a spiral tower. The vortex tube-type membrane component is capable of improving anti-pollution capability, improving membrane separation capability, prolonging membrane service life greatly, and reducing operation cost, and shapes like a vortex line; membrane tube diameter is changeable; 70 to 85% energy is saved; aeration is not needed; low cost operation is realized; automatic adjustment of membrane passing conditions (such as pressure and tangential force) with the change of medium characteristic parameters (concentration, viscosity, and flow amount) is realized; and the vortex tube-type membrane component is suitable for organic membranes and inorganic membranes of different separation accuracy.

Description

technical field [0001] The invention relates to the technical field of membrane separation, in particular to a vortex tube membrane module and system. Background technique [0002] Membrane separation technology is widely used in water treatment and material separation in various industries. The existing membrane structure, whether it is a flat membrane, a hollow fiber membrane, a roll membrane or a tubular membrane, all of its filtration forms are vertical filtration. In many occasions, such as reclaimed water reuse, advanced sewage treatment, zero discharge, material separation and other occasions with high requirements, this form of filtration has the problem of difficulty in improving the separation efficiency to varying degrees. It is characterized by the precipitation and accumulation of dirt in the liquid on the surface of the membrane and in the pores of the membrane, resulting in fouling of the membrane surface, clogging of the membrane pores, reduction of membrane...
