Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

As shown in Figures 1 to 5, which includes: that pole piece 1, insulating spacer 3 and gasket 4 form, wherein pole piece 1 includes positive plate 1a and negative electrode tab 1b.

Electro-desalting component in the present embodiment is in rectangular parallelepiped structure.

Pole piece 1 selects the prior art, has multipair, and side length is respectively m, n.

Insulating spacer 3 selects the prior art, which is provided with the runner that water supply stream passes through, side length is respectively m+5mm, n+ 5mm。

Gasket 4 is cricoid rectangle structure, and the width on four sides is 20mm, and in-between through-hole side length is respectively m+ 3mm and n+3mm.

Gasket with a thickness of 0.35mm, pole piece with a thickness of 0.2mm, insulating spacer with a thickness of 0.15mm.

The assembling structure of pole piece, insulating spacer and gasket is as follows:

With positive plate → insulating spacer → gasket → negative electrode tab → insulating spacer → gasket be one group, successively stack to The number of plies needed；Positive plate can be exchanged with negative electrode tab.

The tubular structure with intermediate throughholes 41 is formed after each gasket overlapping, each pole piece 1 and insulating spacer 3 are accommodated in this In through-hole 41.The sum of the thickness of gasket and thickness of positive plate, negative electrode tab and insulating spacer are adapted.

The peripheral part of the periphery of insulating spacer 3 and the gasket 4 overlaps, and lamination portion width is 3mm.

Positive plate 1a connection positive pole (not shown), the negative electrode tab 1b connection power cathode (do not show in figure Out).For positive plate 1a in the present embodiment there are two access point, two access points connect the electricity by two conducting wires in parallel Source anode；It also is provided with two on negative electrode tab 1b to be electrically accessed a little, each access point connects the power supply by two conducting wires in parallel and bears Pole.

Two on each pole piece be electrically accessed a little can be located at pole piece it is same on one side on, can also be on different sides；Such as Fig. 3 institute Show that two are electrically accessed point E, F and are located in the long side of pole piece, the distance between two access points and side midpoint O are；m For the side length of long side.
