Rolling type electric adsorption filter element

Abstract

The invention relates to a roll typed electric adsorption filter core. The invention has the structure that a roll typed electric adsorption component part is arranged inside a casing, and a liquid inlet, a liquid outlet and an electrode are arranged in the casing. A composite layer, which is composed of a conductive layer, a adsorption layer, a supporting layer, a adsorption layer, a conductive layer, a adsorption layer, a supporting layer and a adsorption layer (totally eight layers), winds on the core shaft, and the fixing layer on the lateral side tightens the composite layer to make the composite layer fixed on the core shaft. When original liquid enters into the filter core through the liquid inlet, and while passing the supporting layer of the roll typed electric adsorption component parts, the charged particles (like metal ions: calcium, magnesium, sodium, lead, mercury, cadmium and so on, and acid radical, etc) are absorbed in the electric double layer on the surface of adsorption layer under the effect of direct current electric field force, and then are effectively removed, and so the liquid is purified. The fluid flow of the roll typed electric adsorption filter core distributes evenly and has strong adaptability to original liquid. The invention has good purification effect, low operation energy consumption, simple structure, low manufacture cost and long useful life, and can purify water, wine, beverage and other liquids.

Description

technical field

[0001] The invention relates to the technical field of liquid treatment, in particular to a roll-type electric adsorption filter element. Background technique

[0002] The shortage of fresh water resources is one of the serious problems facing the world, and desalination of seawater or brackish water and reuse of reclaimed water are the fundamental ways to solve this problem. Therefore, it is of great significance to develop water treatment technologies with low cost, low energy consumption, strong adaptability and good stability.

[0003] In the technical field of seawater or brackish water desalination, currently known technologies mainly include distillation, reverse osmosis, ion exchange, electrodialysis and EDI. However, these techniques have obvious deficiencies. For example: distillation technology consumes a lot of energy; reverse osmosis technology has high equipment cost, strict requirements for water pretreatment, and high operating pressure, so ...

Embodiment 2

[0036] Embodiment two: shown in conjunction with Fig. 8 and Fig. 9, this embodiment is a kind of simplification to embodiment one, filter layer (5), blocking layer (16), connector (18) and The inner extension short pipe above the liquid outlet (20) is cancelled, and the roll-type electro-adsorption assembly (27) with the structure shown in Figure 8 is arranged in the housing, and the outer surface of the roll-type electro-adsorption assembly (27) fixed layer and the inside of the body are arranged. The side faces are sealed and fixedly connected by a sealing material (28). In order to prevent the ion exchange resin from leaking, barrier layers (26) are respectively arranged at both ends of the support layer of the roll-type electro-adsorption component. Other requirements of this embodiment are the same as those of Embodiment 1.
