Embodiment 1

[0025] See figure 1 : The flat membrane separator 1 is horizontally arranged on the central axis 2 vertical to the ground, driven by the eccentric link mechanism 4 of the motor 3, the central axis can reciprocate and swing within a certain radial angle, so that a horizontal shear force is generated on the membrane surface . Under the action of this force, the fouling layer deposited on the horizontal membrane surface is reduced or destroyed by the shear force, and the work of the membrane separator is less affected by the fouling.

Embodiment 2

[0027] See figure 2 Roll-type membrane separator 1 is vertically fixed on the vibrating frame 7, the vibrating frame is supported on the spring 5, the material passes through the membrane tube from the horizontal direction, the motor 3 is also fixed on the frame 7, and the rotating shaft of the motor 3 is fixed with an eccentric weight Object 6. When the motor 3 rotates at high speed, the eccentric weight 6 generates a reciprocating vibration force on the vibrating frame 7, causing the vibrating frame 7 to reciprocate up and down, and the vibrating frame 7 drives the membrane separator 1 to shake and reciprocate up and down. Therefore, the substances adhered to the membrane surface of the vertically arranged tubular membrane separator 1 are destroyed by the shear force, reducing or no longer affecting the work of the membrane separator.

Embodiment 3

[0029] See image 3 The tube-membrane separator 1 is fixed on the vibrating frame 7, and the vibrating frame 7 is supported on the spring 5, and the material passes through the membrane tube in the horizontal direction. The motor 3 and the spring 5 are fixed on the spring base plate 8, and the vibrating frame 7 and the membrane separator 1 are reciprocated up and down through the eccentric link mechanism 4, so that the material adhered to the membrane tube wall of the membrane separator 1 is subjected to shear force Destroy, reduce or no longer affect the operation of the membrane separator.

Abstract

The vibration bed membrane separator is fixed on the vibration bed to make the material implement vertical reciprocating movement passing through membrane direction with vibration bed, the invented advantage is lies in that the vibration bed can effectively control pollution of membrane surface of membrane separator, can make membrane separator high-effectively stable work for a long period. It is favorable for concentration of high concentration material, and can expand working range of membrane separator.

Description

Technical field: [0001] The invention relates to a special equipment using membrane separation method, especially a vibrating bed membrane separator. Background technique: [0002] Membrane separator is a device that uses the tiny pore size and chargeability of the membrane surface to separate substances with different molecular weights or different electrical properties in gases or liquids. At present, membrane separators have been used in seawater desalination and desalination; drinking and medicinal water to remove impurities and bacteria; industrial high-purity water to remove charged ions; bioengineering fermentation liquid to remove bacteria and concentrate macromolecules; pharmaceutical engineering, daily chemical engineering Extracting active ingredients; used in environmental protection for sewage purification and reuse; used in alcohol production for high-concentration, low-energy alcohol production; atomic energy engineering for the separation of radioactive subst...
