Dielectrophoresis flat permeable membrane component

Abstract

The invention relates to a dielectrophoresis flat permeable membrane component, which is a membrane stack structure composed of a left shell, a right shell, permeation mainboards, permeation frame boards, permeation membrane boards, and electrodes. The permeation mainboards and the permeation frame boards are fixedly arranged between the left shell and the right shell at intervals. The permeation membrane boards are hermetically installed between adjacent permeation mainboards and permeation frame boards, and electrode pairs are transversely and uniformly distributed and mounted on the permeation frame boards at intervals. The component employs a dielectrophoresis technology to reduce or even eliminate membrane fouling and membrane blocking phenomena in a permeation process by a physical way, so that a membrane element itself can form a fluid passage and a liquid cavity, the membrane permeation amount can be enhanced, and the problems that existing flat membrane elements cannot break away from a pool, a positive pressure cannot be added for permeation and the membrane surfaces are likely to be polluted and blocked can be overcome perfectly. Thus, the dielectrophoresis flat permeable membrane component has very high innovativeness.

Description

technical field [0001] The invention belongs to the technical field of separation, and relates to a permeable membrane filtration separation process, in particular to a dielectrophoresis flat permeable membrane component. Background technique [0002] Membrane separation technology represented by polymer functional membrane has achieved remarkable development in the past 50 years. Except for dialysis membranes which are mainly used for medical treatment, almost all functional membranes can be used in petroleum, natural gas, petrochemical, light industry, electronics, electric power, food and other industries. Membrane engineering technology and the integration technology of membrane technology and other technologies will gradually replace the current traditional separation technology in a targeted manner, and will have a profound impact on the fields of chemical industry, petrochemical, petroleum and environmental protection. [0003] As a form of membrane module, the flat ...
