Abstract

The utility model provides a kind of EDI essence demineralizer, including EDI module, spaced freshwater room and concentrated water room are equipped in EDI module, partition is provided between freshwater room and concentrated water room, anion-exchange membrane, cation-exchange membrane are equipped at intervals on partition, the No.1 square body and No. two square bodies that can be embedded in annular recess that the partition is surrounded by annular recess by one form, and anion-exchange membrane or cation-exchange membrane and No. two square bodies are connected in the annular recess of No.1 square body simultaneously.The utility model is compared with traditional technology, anion-exchange membrane and cation-exchange membrane are fixed on more secured on partition, since the area of spacers block water flow is greatly reduced, water flow circulation is more unobstructed, the design of rectangle groove body is so that most of sediment has been fallen in groove body, so that the frequency of cleaning device is reduced.

Description

EDI essence demineralizer

Technical field

The utility model relates generally to water treatment field, primary for last in all types of industries boiler replenishing water processing system Walk smart desalination more particularly to a kind of EDI essence demineralizer.

Background technique

For EDI essence demineralizer mainly under the action of DC electric field, it is fixed to be occurred by dielectric ion in the water of partition To movement, effect is penetrated come a kind of water treatment technology of the science purified to water quality to the selection of ion using exchange membrane. It between a pair of electrodes of electric dialyzator, is usually alternately arranged by cavity block, anode membrane and partition (first, second) multiple groups, constitutes dense room and light Room (i.e. cation permeable anode membrane, anion can pass through cavity block).Cation migrates through anode membrane to cathode in light room water, dense Cavity block retention in room；Anion migrates cavity block to positive extreme direction in water, is retained by the anode membrane in dense room, passes through light room in this way Water intermediate ion number gradually decreases, and becomes fresh water, and in the water of dense room, since the zwitterion of dense room is constantly poured into, dielectric from Sub- concentration constantly increases, and becomes concentrated water, to achieve the purpose that desalination, purification, concentration or purification.

EDI essence demineralizer is traditional usually since the heat damage of amberplex and consumption need replacing and clear up Amberplex is often embedded at the side of partition, when other side water flow pressure is excessive, is easy to cause and falls off, causes EDI module Failure, and partition in the prior art block water flow area it is excessive, be unfavorable for passing through for water flow.

Utility model content

Purpose of utility model: the purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of EDI essence desalination The innovative point of device, the utility model is that amberplex is more firmly fixed on partition, and partition blocks flow plane Product greatly reduces.

Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is such completion: EDI essence desalination Device, including EDI module are equipped with spaced freshwater room and concentrated water room in EDI module, are arranged between freshwater room and concentrated water room There is partition, anion-exchange membrane, cation-exchange membrane are equipped at intervals on partition, the partition is surrounded by annular recess by one No.1 square body and a No. two square bodies composition that can be embedded in annular recess, anion-exchange membrane or cation-exchange membrane It is connected in the annular recess of No.1 square body simultaneously with No. two square bodies.Anion-exchange membrane or cation-exchange membrane and No. two Square body is connected in the groove of No.1 square body simultaneously, in conjunction with it is more secured, and partition is without blocking water flow part, water flow stream It is logical more unobstructed.

Further, No. two square column volume surroundings are anti-corrosion layer of silica gel.Further increase leakproofness.

Further, the bottom of the No.1 square body, annular recess the back side be equipped with rectangle groove body.It is handed in anion Changing the precipitating formed at film and cation-exchange membrane can be deposited in rectangular slot body.

Further, the No.1 square body and rectangle groove body are flexibly connected, and clean the intracorporal sediment of rectangular slot Matter is more convenient.

Further, No. two square column body sidewalls are equipped with several No. two through-holes, set in the both sidewalls of annular recess After having several No.1 through-holes corresponding with No. two through-holes, No.1 square body and No. two square bodies to be clamped, fastener is also cross one Number through-hole and No. two through-holes.It further strengthens anion-exchange membrane and cation-exchange membrane is fixed on firmness on partition.

The utility model has the beneficial effects that the utility model has the advantages that compared with traditional technology

1, compared with traditional technology, anion-exchange membrane and cation-exchange membrane are fixed on partition more the utility model Securely, since the area of spacers block water flow is greatly reduced, water flow circulation is more unobstructed；

2, in the utility model the design of rectangle groove body so that most of sediment has been fallen in groove body, so that cleaning dress The frequency set is reduced.

Detailed description of the invention

Fig. 1 is the schematic diagram of No.1 square body.

Fig. 2 is the schematic diagram of No. two square bodies.

Specific embodiment

As shown in Figure 1, 2, EDI essence demineralizer, including EDI module, be equipped in EDI module spaced freshwater room and Concentrated water room is provided with partition, anion-exchange membrane, cation-exchange membrane is equipped at intervals on partition between freshwater room and concentrated water room, No.1 square body 1 that partition is surrounded by annular recess 3 by one and one can be embedded in No. two square bodies 2 of annular recess 3 Composition, anion-exchange membrane or cation-exchange membrane and No. two square bodies 2 are connected to the annular recess 3 of No.1 square body 1 simultaneously In, No. two 2 outer layers of square body are anti-corrosion layer of silica gel, and the bottom of No.1 square body 1, the back side of annular recess 3 are equipped with rectangular slot Body 4, No.1 square body 1 and rectangle groove body 4 are flexibly connected, and No. two 2 side walls of square body are equipped with several No. two through-holes 5, cyclic annular The both sidewalls of groove 3 are equipped with several No. two through-holes 6 corresponding with No.1 through-hole 5 on 1 side wall of No.1 square body, No.1 square column After body 1 and the clamping of No. two 2 bodies of rectangle column, fastener passes through No.1 through-hole 6 on No.1 square body 1 and No. two square bodies 2 On No. two through-holes 5.
