Description

[Detailed Description of the Invention] The present invention relates to an electrolytic cell, and particularly provides an electrolytic cell having a structure that is easy to maintain and inspect.

Conventionally, there are various structural types of electrolytic cells used, for example, in sea ice and salt water electrolyzers, but one method is for electrolytic cells in which flat plate anodes and cathodes are arranged alternately in parallel. There is a structure as shown in FIG.

A cross-sectional view of the electrolytic cell is shown in FIG.

Although FIG. 2 is an exploded view, a spacer 7 which also serves as a watertight gasket is sandwiched between an anode 1 and a cathode 2, and the anodes and cathodes are alternately stacked.

Reference numeral 8 denotes a rectifier piece whose external dimensions match the holes 3 and 4 between the anode and cathode.

Reference numerals 9 and 10 are end plates positioned after the hole with the electrode plate group sandwiched therebetween, and a seawater population 11 and a seawater outlet 12 are provided in the end plate 9 in front of the electrode plate group.

Reference numeral 13 denotes bolts for tightening the end plates 9 and 10 from both sides.

The disadvantages of such devices are as follows.

(a) Internal inspection of the electrolytic cell is not easy.

(b) When replacing the electrodes, it is necessary to completely disassemble the electrolytic cell.

The present invention aims to eliminate the above-mentioned drawbacks and provides an electrolytic cell device having the following features.

(i) The electrodes must be assembled into an anode block and a cathode block and housed inside the electrolytic cell body.

(ii) If one current-carrying terminal is attached to the anode block and cathode block inside the electrolytic cell main body, the above-mentioned current-carrying terminal is taken out outside the electrolytic cell main body.

Hereinafter, the apparatus according to the present invention will be explained based on an embodiment shown in FIGS. 5 to 11.

This electrolytic cell device is composed of an electrode and a container containing the electrode, that is, an electrolytic cell body.

The main body of the electrolytic cell is the lower lid 21 in Fig. 5. It is composed of a body 22 and an upper lid 23, and the electrodes are composed of an anode block shown in FIGS. 10 and 9 and a cathode block shown in FIGS. 12 and 11.

The anode block shown in FIGS. 10 and 9 includes a plurality of anode plates 24, a comb-like metal fitting 25, a current-carrying terminal 26, and bolts 28, 2.
9. It is composed of a pipe 27.

The plurality of anode plates 24 and the joining metal fittings 25 are composed of several poles)
28, 29 and pipe 27 are firmly assembled into one piece.

The anode plate 24 is made of a material such as a titanium base material coated with platinum or ruthenium, or a material that can be used for electrolysis of seawater or salt water, such as carbon.

On the other hand, a metal fitting 25 that integrally assembles this anode plate 24
, bolts 28, 29, pipe 27, etc. are made of a material that does not corrode electrically, such as titanium.

Further, one current-carrying terminal 26 is attached to the anode block, and the outer shell of the current-carrying terminal 26 is made of a highly corrosion-resistant material such as titanium 7, but the inside is embedded with copper C to increase the current-carrying capacity. be.

Therefore, the dimensions of this current-carrying terminal 26 can be made quite small.

The cathode block shown in FIGS. 112 and 11 includes a plurality of cathode plates 3.
0 is incorporated in a comb shape by bolting or welding,
Moreover, one current-carrying terminal 31 is attached to the cathode block.

In this state, the anode plate 24 of the anode block shown in FIG.
are assembled so as to be alternately inserted between the comb-shaped cathode plates 30 of the cathode block, and housed in the body 22 of the electrolytic cell shown in FIG.

The assembled state of this electrode is shown in FIG.

The distance between the cathode plate 30 and the anode 24 is maintained by an insulating material 33,
This is done using 34.

When the electrode is housed in the electrolytic cell body, the current-carrying terminal 26 of the anode is fixed to the coupling metal fitting 25 with bolts 29, and the lid 35 is closed.

On the other hand, the cathode current-carrying terminal 31 is fixed to the cathode plate 30 with bolts 32 and covered with a lid 36.

Seawater or salt water is electrolyzed by flowing current through the current-carrying terminal portion while seawater is supplied from the flange portion of the lower lid 21, flows through the gap between the cathode and the anode, and is discharged from the flange portion of the upper lid 23. become.

In the case of this embodiment, the anode and cathode current-carrying terminals 26 and 31 are 1
Although the case of a book is shown, a plurality of books may be used to increase the current carrying capacity.

As specifically explained above, the electrolytic cell device according to the present invention has a plurality of anode plates arranged in parallel between the joint pieces of the comb-shaped composite for the anode, and the plurality of anode plates and the plurality of anode plates. The connecting piece is held by a bolt that passes through the connecting piece, and one power supply rod for the anode is protruded from the comb-like joint for the anode to form an anode block. A comb-shaped cathode object and a cathode bonding structure having one cathode power supply rod protruding from each other are held together by an inserting bolt to form a cathode block, and the anode block and the cathode block are connected to the anode plate and the cathode block. The electrolytic electrodes are arranged in parallel with the cathode plates alternately to form electrodes, and the electrolytic electrode is attached so that the anode power supply rod and the cathode power supply rod protrude from the body, and a removable electrode is attached to both sides of the above side. Since a lid is provided and a lower lid and an upper lid are provided below and above the thoracotomy, by removing the lid of the electrolytic cell body, the inside of the electrolytic cell can be approached, making internal inspection easier.

Further, the electrodes require periodic cleaning, and in this case as well, the interior can be easily cleaned by removing the lid.

Further, the anode needs to be replated or replaced once every few years, but in this case, the anode block can be easily pulled upward by removing the lid.

The sealing surfaces between the lid and the body of the electrolytic cell are all flat sealing surfaces, which has the advantage of preventing water leakage from the main body.

In the illustrated example, a material with low electrical resistance, such as copper, is embedded in titanium at the current-carrying terminal of the anode to increase the current-carrying capacity.
