Embodiment Construction

[0037] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0038] A dielectrophoresis disc-tube membrane module, which is mainly composed of a pressure-resistant shell 12, a power supply end cover 5, a water inlet end cover 7, a diversion plate 6, a disc-type membrane bag 16, an electrode plate 17, and a central tie rod 1 . The power end cover, multiple deflector plates and water inlet end cover are stacked in sequence, and the middle part is fixed by a central pull rod. The upper center pull rod on the upper part of the power end cover is fitted with an upper sheath 3, and the upper part of the upper sheath is installed with a lock. Mother 2. The lower sheath 9 is set on the central pull rod at the bottom of the water inlet end cover, and the lower lock nut 10 is installed. An insulating liner is...

Abstract

The invention relates to a dielectrophoresis butterfly tube type membrane component. A power supply end cover, a plurality of diversion discs and a water inlet end cover are overlapped in sequence; a central pull rod is fixed in the centers of the components in a penetration mounting manner; a pressure-resistant shell is fixedly mounted outside the power supply end cover and the water inlet end cover in a sealing manner; a raw water channel is formed between the peripheries of the diversion discs and the pressure-resistant shell; a filtering channel is formed in the middle of each diversion disc; a generated water channel is formed between the centers of the diversion discs and the central pull rod; butterfly type membrane bags are arranged between every two adjacent diversion discs in an overlapped manner; electrode plates are mounted inside the overlapped membrane bags; binding posts are mounted inside the inner ends of the electrode plates; every two adjacent electrode plates form a fork electrode; a raw water inlet which is communicated with the raw water channel is formed in the water inlet end cover; a generated water outlet which is communicated with the generated water channel and a concentrated water outlet which is communicated with the filtering channel are formed in the water inlet end cover. Due to adoption of a dielectrophoresis technique, the purposes that concentration polarization is reduced, membrane pollution is prevented, the service life of membranes are prolonged, the electroosmosis effect is achieved, the filtering effect of the membranes is improved, the water generation amount of the membranes is increased and the energy consumption can be reduced are achieved.

Description

technical field [0001] The invention relates to a disc-tube membrane separation device, in particular to a dielectrophoresis disc-tube membrane module. Background technique [0002] The disc-tube membrane module was developed for landfill leachate treatment. It was successfully developed by RECHEM in 1988 with the support of the German government. Compared with other membrane modules, the disc-tube membrane module has the following three obvious features: [0003] Channel width: The channel between the membranes is 6mm, while the roll-packed membrane module is only 0.2mm. [0004] Short flow: The flow of liquid on the surface of the membrane is only 7cm, while the roll-packed membrane module is 100cm. [0005] Turbulent flow: Due to the effect of high pressure, the leachate hits the bumps on the guide plate to form high-speed turbulent flow. Under the scouring of this turbulent flow, the surface of the membrane is not easy to settle pollutants. In the roll-packed membrane...
