DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an electrolytic cell for producing acidic water and / or alkaline water by electrolysis of water, and more particularly, to a non-diaphragm type electrolytic cell.

[0002]

2. Description of the Related Art Conventionally, an electrolyzer for producing acidic water and alkaline water by electrolysis of water is divided into a non-woven fabric, an unglazed plate, etc., at the center of opposed electrodes by a diaphragm which partially restricts the passage of water. By applying voltage to both electrodes, water is electrolyzed to generate acidic water and alkaline water.

[0003]

However, a problem of the electrolytic cell using the above-mentioned diaphragm is that bacteria and microorganisms may adhere to and proliferate on the diaphragm. This is to cause clogging and cut off the flow of current to lower the electrolysis efficiency.

That is, bacteria such as Escherichia coli easily inhabit the water-wetted membrane, and the above-mentioned membrane is attracted to the electrodes and cations are drawn toward the cathode and anions are drawn toward the anode. Although it will pass, this ion is not limited to hydroxyl ions and hydrogen ions, but also includes calcium ions, magnesium ions, and silicon contained in water, and the silicon itself is an insulator, This is because calcium ions and magnesium ions become insoluble and insulating precipitates such as magnesium carbonate and calcium carbonate and adhere to and deposit on the diaphragm.

Accordingly, the present invention has been made to solve the above-mentioned problems, and an electrolytic cell which can omit a diaphragm, has no breeding source of bacteria and microorganisms, and can guarantee efficient electrolysis for a long period of time. The purpose is to provide.

At the downstream side of (a), an acidic water collecting gap (18) is provided which is open in a plane passing through the working surface of the anode plate (8), and the acidic water collecting gap (18) is connected to the acidic water outlet (3). ), The acidic water generated by the electrolysis of water and flowing along the anode plate (8) is converted from the alkaline water flowing along the cathode plate (9) at the downstream portion of the electrolytic flow path (7a) by electrolysis. The flow path (7a) is characterized in that it is separated in a horizontal direction with respect to the flow in the flow path (7a).

Therefore, in the electrolytic cell of the present invention, since the gap between the electrode plates 8 and 9 is set to be minute, the water flowing into the electrolytic flow channel 7a from the water inlet 2 is supplied to the electrode plates 8 and 9. While flowing along the surface, the water flow is subjected to a viscous action, and the water flow becomes a laminar flow, which is referred to in hydrology, while flowing in the electrolytic flow channel 7a.

Further, since a gap 18 for collecting acidic water is provided at a downstream portion of the electrolytic flow channel 7a, which is opened in a plane passing through the working surface of the anode plate 8, it is generated by electrolysis of water and electrolyzed along the anode plate 8. The boundary layer of the acidic water that has flowed to the downstream side of the flow path 7a is separated from the boundary layer of the alkaline water that has flowed along the cathode plate 9, and is laterally extracted from the flow in the electrolytic flow path 7a. Will be issued. As described above, since the boundary layer of the acidic water is extracted in the lateral direction from the flow in the electrolytic flow channel 7a, the acidic water and the alkaline water are separated without generating a turbulent flow in the downstream portion of the electrolytic flow channel 7a. And strong acidic or alkaline water can be recovered.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes an electrolytic cell, and the electrolytic cell 1 is formed in a thin vertical two-part container shape by one side container part 1a and the other side container part 1b. It is a matter of course that both the one-side container part 1a and the other-side container part 1b are made of a waterproof material such as a synthetic resin. It is desirable to use a material. Also, this one-side container part 1
a and the other-side container portion 1b are formed in a thin container shape having airtightness by inserting a packing 11 into the fitting portion and fixing each other with fastening screws 12, 12, 12,....

A tap water inlet 2 is provided at one end of the electrolytic cell 1, and an acidic water outlet 3 and an alkaline water outlet 4 are provided at the other end. That is, in the electrolytic cell 1, the tap water flowing from the tap water inlet 2 flows out of the acidic water outlet 3 and the alkaline water outlet 4 through the electrolytic bath 1.

Further, in a portion of the electrolytic cell 1 downstream of the portion where the tap water inlet 2 communicates, the cross-sectional area of the tap water inlet 2 is smaller than the cross-sectional area of the tap water inlet 2 over substantially the entire width of the electrolytic bath 1. Weir 5 forming slit-shaped constricted flow path 10
A tank chamber 6 having a predetermined capacity and the same width as that of the slit-shaped constricted flow path 10 is provided upstream of the weir 5. In the present application, the total width of the electrolytic cell 1 is the inner dimension in the left-right direction of “FIG. 1” and “FIG. 2”.

The slit gap (the width in the left-right direction in FIG. 3) of the slit-shaped constricted flow channel 10 is smaller in the cross-sectional shape of the slit-shaped constricted flow channel 10 than in the cross-sectional shape of the tank chamber 6. It is set as follows. In the illustrated embodiment, a pre-stage weir 5a is also provided at the upstream part of the weir 5, and a pre-stage tank chamber 6a is further provided at the upstream part thereof so that water passes through the two stages of the weir 5 and the pre-stage weir 5a. But this front stage weir 5a
And the former tank chamber 6a may be omitted. Also, the weir 5 is provided with rectifying projections 13, 13, 13,... In the vertical direction as shown most clearly in FIG. 2, but the rectifying projections 13, 13, 13,. It is possible.

In the electrolytic cell 1, an electrolytic cell chamber 7 is provided on the downstream side of the slit-shaped constricted flow path 10. In the electrolytic cell chamber 7, a pair of flat anode electrode plates 8 and cathode electrodes are provided. The plate 9 is accommodated in parallel at the center thereof with an electrolytic flow channel 7a communicating with the tank chamber 6 through the slit-shaped narrow flow channel 10 in parallel. The gap between the electrode plates 8 and 9 is set so small that a laminar flow is formed in the electrolytic flow channel (7a) when flowing water.

The material of the anode electrode plate 8 and the cathode electrode plate 9 is not particularly limited, but it is a matter of course that a corrosion-resistant metal is used. The application of a predetermined DC voltage by the power supply device as shown in FIG. 5 is the same as in the prior art.

In the power supply device shown in FIG. 5, reference numeral 31 denotes a transformer, 32 denotes a rectifier, 33 denotes a ballast circuit, 34 denotes a water pressure switch, and 35 denotes an applied voltage switch, which are connected as shown.

As shown in FIG. 4, the water pressure switch 34 is such that the power supply circuit is closed when water pressure is applied to the flow path. In the example of FIG. A reduced diameter portion 41 is provided in the middle of the conduit body 40 to be interposed at an appropriate position such as a portion, and a piston 42 that can enter and exit from a cylinder is inserted into a portion upstream of the reduced diameter portion 41 of the conduit body 40,
The water pressure switch 34 composed of a micro switch is opened and closed by the movement of the piston 42. In FIG. 4, reference numeral 43 denotes a packing, and 44 denotes a packing 4.
A pressing ring 3 and a packing 45 are shown. In the figure, the spring is not shown.
Goes down and the water pressure switch 34 is open (OFF state)
It is made to become.

In the power supply device, a voltage is applied such that the anode electrode plate 8 is always on the left side and the cathode electrode plate 9 is on the right side. Is applied in reverse. Note that this reverse application is performed in order to release the deposits and deposits by applying a reverse current when cleaning the electrode surface as is conventionally performed.

The slit-shaped constricted flow path 10 and the electrolytic flow path 7a between the anode electrode plate 8 and the cathode electrode plate 9 are
It is more practical to have substantially the same dimensions and to be on substantially the same plane since turbulence is unlikely to occur in the flow of water.

The upstream end of the acidic water outlet 3 is located on the anode electrode plate 8 side downstream of the electrolytic flow channel 7a, and the upstream end of the alkaline water outlet 4 is located downstream of the electrolytic flow channel 7a. Communication with the side.

That is, the acid water outlet 3 has its upstream end located on the anode electrode plate 8 side downstream of the electrolytic flow channel 7a, so that it flows along the surface (working surface) of the anode electrode plate 8 and is subjected to acid electrolysis. Out of the water, the alkaline water outlet 4
Flows upstream along the surface (working surface) of the cathode electrode plate 9 on the downstream side of the electrolytic flow channel 7a so that water alkalized by electrolysis flows out.

In the illustrated embodiment, a gap 18 for recovering acidic water is provided on the downstream side of the electrolytic flow channel 7a, and is open on the surface (working surface) of the anode electrode plate 8, and is provided along the surface of the anode electrode plate 8. The flowing acidic water is laterally extracted from the flow in the electrolytic flow channel 7a. The extracted acidic water flows from the acidic water collecting gap 18 into the turn-back channel 15, and flows out from the acidic water outlet 3 provided at the downstream end of the turn-around channel 15. In the illustrated embodiment, a collision plate 14 corresponding to substantially half of the electrolytic flow channel 7a on the anode electrode plate 8 side is provided, so that the acidic water can be easily extracted. In addition,
The folded flow path 15 is formed in a bulged portion 16 (see FIG. 1) bulged in the one-side container portion 1a and is located along the back surface of the anode electrode plate 8.

Therefore, in the illustrated embodiment, the influence of the turbulent flow which may occur at the upstream portion of the acid water outlet 3 is
The position of the acidic water outlet 3 is set at a distance from the downstream end of the anode electrode plate 8, and the return flow path 15 is prevented from functioning as a tank chamber for collecting acidic water having a predetermined capacity.

Further, in the illustrated embodiment, the water flowing along the surface of the cathode electrode plate 9 passes through an alkaline water recovery gap 19 formed between the collision plate 14 and the other side container 1b as it is. To go straight, but the electrolytic flow path 7a
An alkaline water recovery tank chamber (downstream tank chamber) 17 having a predetermined capacity which communicates with the electrolytic flow path 7a via an alkaline water recovery gap 19 is provided downstream of the alkaline water outlet 4. The upstream end communicates with the alkaline water recovery tank chamber 17.

That is, the alkaline water recovery tank chamber 17 is interposed between the alkaline water outlet 4 and the electrolytic flow channel 7a, and has a predetermined capacity to make local pressure fluctuation uniform. Therefore, in the illustrated embodiment, the influence of the turbulent flow which may occur at the upstream portion of the alkaline water outlet 4 is avoided by the action of equalizing the pressure fluctuation of the alkaline water recovery tank chamber 17.

The above-described acidic water recovery tank chamber (return channel) 15 and alkaline water recovery tank chamber (downstream tank chamber) 17 are not necessarily required, as described above. When the area with the cathode electrode plate 9 is reduced to achieve compactness, it has a remarkable turbulence prevention effect. In the illustrated example, one of the anode electrode plate 8 and the cathode electrode plate 9 serves as an acidic water recovery tank chamber (return channel) 15 and the other serves as an alkaline water recovery tank chamber 17. Alternatively, even if the downstream tank chamber 17 is used, there is no problem.

In the figure, 21 is a screw hole for fastening the electrolytic cell,
Reference numeral 22 denotes a screw hole for fixing the electrode plate, and reference numeral 23 denotes a hole for extracting a lead wire of the electrode.

[0032]

As described above, the present invention does not use a diaphragm, which has been conventionally required, so that bacteria and bacteria
The present invention can provide an electrolytic cell that can be stably used for a long period of time without any microorganisms adhering and of course eliminating the fear of clogging of the diaphragm.

Further, in the present invention, although the diaphragm is omitted, the water passing through the electrode gap becomes a clean laminar flow due to the reduced electrode gap, and the alkaline water and the acidic water to be electrolyzed are not mixed, and the electrolysis efficiency is reduced. Not only does not decrease, but rather the diaphragm does not act as a kind of insulating material, so that the electrolytic efficiency is increased and an efficient electrolytic cell can be provided.

A gap 18 for recovering acidic water and / or a gap 19 for recovering alkaline water are provided at a downstream side of the electrolytic flow channel 7a. The gap 18 is open to a plane passing through the working surface of the anode plate 8 and / or the cathode plate 9. The boundary layer of the acidic water generated by the electrolysis of water and flowing along the anode plate 8 to the downstream portion of the electrolytic flow channel 7a and / or the alkaline water flowing along the cathode plate 9 is: Since the water is extracted in the lateral direction from the flow in the electrolytic flow channel 7a, even if the diaphragm is omitted and the electrode gap is reduced, the turbulent flow does not occur in the downstream portion of the electrolytic flow channel 7a. And strong acidic water or alkaline water can be recovered.
