Abstract

PURPOSE: To abolish a diaphragm and to make electrolysis hygienic and efficient with an electrolytic cell which forms acidic water and/or alkaline water by electrolysis of water. CONSTITUTION: An electrolytic flow passage 7a is formed between an anode plate 8 and a cathode plate 9 by installing both plates 8, 9 oppositely in parallel without interposing a diaphragm therebetween apart such a slight spacing that laminar flow is formed therein at the time of passing water. Since inter-electrode spacing is narrow, the water flow receives the viscous effect while flowing along the surfaces of the electrode plates 8, 9 and forms the laminar flow and the acidic water formed in the anode plate 8 side and the alkaline water formed on the cathode plate 9 side flow without mixing even if there is no diaphragm. The downstream side section of the electrolytic flow passage 7a is provided with a spacing 18 for recovering the acidic water opening at the plane passing the working surface of the anode plate 8. The acidic water which is formed by the electrolysis of the water and is flowing along the anode plate 8 is separated in a direction transverse to the flow in the electrolytic flow passage 7a from the alkaline water flowing along the cathode plate 9.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD 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 diaphragmless electrolytic cell.

[0002]

2. Description of the Related Art Conventionally, an electrolytic cell for producing acidic water and alkaline water by electrolyzing water is divided by a diaphragm that partially limits the passage of water, such as a non-woven fabric and a bisque plate, in the center of an electrode that is placed oppositely. By applying voltage to both electrodes, water is electrolyzed to generate acidic water and alkaline water.

[0003]

However, the problem with the electrolytic cell using the above-mentioned diaphragm is that bacteria and microorganisms may adhere to the diaphragm and grow over time. This is to cause clogging, interrupt the flow of current, and reduce electrolysis efficiency.

That is, bacteria, such as Escherichia coli, are likely to live in the diaphragm wet with water, and the diaphragm is attracted by the electrodes to allow cations toward the cathode side and anions toward the anode side. Although it will pass, this ion is not limited to hydroxide ion and hydrogen ion, but also includes calcium ion, magnesium ion, and silicon content contained in water, and the silicon content is an insulator itself, This is because calcium ions and magnesium ions become insoluble and insulative precipitates of magnesium carbonate, calcium carbonate, etc. and adhere to and deposit on the diaphragm.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and an electrolytic cell capable of guaranteeing efficient electrolysis for a long period of time by omitting a diaphragm, having no breeding source of bacteria and microorganisms. It is intended to provide.

[0006]

The present invention provides a diaphragmless electrolytic cell (1). In one aspect of the present invention, the diaphragmless electrolytic cell (1) is provided with a tap water inlet (2). And a container (1a / 1b) having an acidic water outlet (3) and an alkaline water outlet (4). A pair of flat plate-shaped anode plate (8) and cathode plate (1a / 1b) are provided in the container (1a / 1b). By arranging 9) in parallel with each other without interposing a diaphragm between them and with a minute gap such that a laminar flow is formed when water is passed, an electrolytic flow is generated between the electrode plates (8, 9). Road (7a)
And the downstream side portion of the electrolytic flow channel (7a) is communicated with the alkaline water outlet (4), and the electrolytic flow channel (7) is formed.
An acidic water recovery gap (18) opening in a plane passing through the working surface of the anode plate (8) is provided at the downstream side of (a), and the acidic water recovery gap (18) is connected to the acidic water outlet (3). ), Acidic water generated by electrolysis of water and flowing along the anode plate (8) is electrolyzed from alkaline water flowing along the cathode plate (9) at a downstream side portion of the electrolytic flow path (7a). It is characterized in that the flow is separated laterally with respect to the flow in the channel (7a).

Therefore, in the electrolytic cell of the present invention, the gap between the electrode plates 8 and 9 is set to be small, so that the water flowing from the clean water inlet 2 into the electrolytic flow path 7a flows into the electrode plates 8 and 9. While flowing along the surface, it is subjected to a viscous action, and the water flow becomes a laminar flow called hydrodynamics while flowing in the electrolytic flow path 7a.

Since the laminar flow has a tendency not to change the flow direction unless the flow path is bent or there is an obstacle in the middle, the water in the electrolytic flow path 7a on the side of the anode electrode plate 8 is the surface of the anode electrode plate 8. Along the surface of the cathode electrode plate 9 on the cathode electrode plate 9 side, and the water and the cathode electrode plate 9 on the anode electrode plate 8 side.

A direct current voltage of a predetermined voltage is applied between the anode electrode plate 8 and the cathode electrode plate 9, and water flowing in the electrolytic flow path 7a between them is electrolyzed while passing through an electric field. Is the same as. Therefore, as water flows through the electrolytic flow path 7a, acidic water is generated along the surface (working surface) of the anode electrode plate 8 and alkaline water is generated along the surface (working surface) of the cathode electrode plate 9. . Since a gap 18 for recovering the acidic water, which opens to a plane passing through the working surface of the anode plate 8, is provided at the downstream side portion of the electrolytic flow path 7a, it is generated along with the anode plate 8 by electrolysis of water. The boundary layer of the acidic water flowing to the downstream side portion of the flow channel 7a is separated from the boundary layer of the alkaline water flowing along the cathode plate 9 and extracted laterally from the flow in the electrolytic flow channel 7a. Will be issued. Since the boundary layer of the acidic water is laterally extracted from the flow in the electrolytic flow path 7a in this manner, the acidic water and the alkaline water are separated without generating turbulent flow in the downstream side portion of the electrolytic flow path 7a. It is possible to recover strong acidic water or alkaline water.

In another aspect of the present invention, in the membraneless electrolytic cell (1), a downstream side portion of the electrolytic flow path (7a) is communicated with the acidic water outlet (3), and the electrolytic flow path (3) is connected. 7

The alkaline water recovery gap (19) is communicated with the alkaline water outlet (4), and the alkaline water generated by electrolysis of water and flowing along the cathode plate (9) flows along the anode plate (8). It is characterized in that the acidic water is separated laterally with respect to the flow in the electrolytic flow channel (7a) at the downstream side portion of the electrolytic flow channel (7a).

In a preferred mode of realization, the container (1a / 1b) is provided with a tank chamber (6) of a predetermined capacity communicating with the tap water inlet (2), and the electrolytic flow channel (7a).
The upstream side of the above is communicated with the tank chamber (6) over almost the entire width thereof.

(17) or the acidic water recovery tank chamber (15), and the acidic water flowing along the anode plate (8) or the alkaline water flowing along the cathode plate (9) is on the downstream side of the electrolytic flow path (7a).

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment 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 configured in a thin vertical two-divided container shape with a one side container portion 1a and another side container portion 1b. It is needless to say 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, but preferably they are insulated to accommodate the later-described anode electrode plate 8 and cathode electrode plate 9. It is desirable to use a material. Moreover, this one side container part 1
The a and the other side container portion 1b are formed into a thin container shape having airtightness by inserting 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 this electrolysis tank 1, tap water flowing in from the tap water inflow port 2 passes through the electrolysis tank 1 and flows out from the acidic water outflow port 3 and the alkaline water outflow port 4.

Further, in a portion of the electrolysis tank 1 downstream of the portion where the tap water inlet 2 communicates, a cross-sectional area smaller than the cross-sectional area of the tap water inlet 2 is formed in the electrolysis tank 1 over substantially the entire width thereof. Weir 5 forming slit-shaped constriction channel 10
And a tank chamber 6 having a predetermined capacity and having the same width as the slit-shaped constriction flow channel 10 is provided upstream of the weir 5. In the present application, the entire width of the electrolytic cell 1 is an inner dimension in the left-right direction of “FIG. 1” and “FIG. 2”, and therefore, the lateral widths of the slit-shaped narrowed channel 10 and the tank chamber 6 are both the electrolytic cell 1
(To be precise, it has the size of the entire width of the electrolytic flow path 7a described later).

The slit gap (width in the left-right direction in FIG. 3) of the slit-shaped narrowed channel 10 is narrower in cross-sectional shape of the slit-shaped narrowed channel 10 than in the tank chamber 6. Is set. In the illustrated embodiment, a pre-stage weir 5a is provided also upstream of the weir 5, and a pre-stage tank chamber 6a is provided further upstream thereof so that water can pass through two stages of the weir 5 and the pre-stage weir 5a. There is this front weir 5a
The front tank chamber 6a may be omitted. Further, as shown most clearly in "FIG. 2", the weir 5 is provided with rectifying protrusions 13, 13, 13 ... In the vertical direction, but the rectifying protrusions 13, 13, 13 ... Are also omitted. It is possible.

An electrolytic cell chamber 7 is provided in the electrolytic cell 1 downstream of the slit-shaped narrowing channel 10, and a pair of flat plate-shaped anode electrode plates 8 and cathode electrodes are provided in the electrolytic cell chamber 7. The plate 9 and the plate 9 are housed in parallel with each other by forming an electrolytic flow path 7a in the center of the plate 9 which communicates with the tank chamber 6 through the slit-shaped narrowed flow path 10. The gap between the electrode plates 8 and 9 is set so small that a laminar flow is formed in the electrolytic flow path (7a) during water flow.

There are no particular restrictions on the materials of the anode electrode plate 8 and the cathode electrode plate 9, but it is needless to say that a corrosion resistant metal is used, and between the anode electrode plate 8 and the cathode electrode plate 9 there is no problem. As in the prior art, a predetermined DC voltage is applied by the power supply device as shown in FIG.

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

As the water pressure switch 34 shown in FIG. 4, a power supply circuit that closes when water pressure is applied to the inside of the flow path is used. In the example of FIG. 4, the tap water inlet 2 is upstream. A reduced diameter portion 41 is provided in the middle of the conduit body 40 to be inserted in an appropriate place such as a portion, and a piston 42 that can be inserted and removed is inserted from a cylinder at a portion upstream of the reduced diameter portion 41 of the conduit body 40,
The water pressure switch 34, which is a micro switch, is opened and closed by the movement of the piston 42. In FIG. 4, 43 is a packing and 44 is the packing 4
The pressing ring 3 and 45 are packings. In addition, although the spring is not shown in the figure, if there is no water pressure, the piston 42
Falls and the water pressure switch 34 is in the open state (OFF state)
It is designed to be.

In the power supply device, a voltage is applied so that the left side is the anode electrode plate 8 and the right side is the cathode electrode plate 9, and when the applied voltage changeover switch 35 is operated, the cathode side and the anode side are connected. Is applied in reverse. It should be noted that this reverse application is for reversely energizing to wash off the surface of the electrode, as is conventionally done, to release the deposits and deposits.

Further, the slit-shaped narrowing channel 10 and the electrolytic channel 7a between the anode electrode plate 8 and the cathode electrode plate 9 are
It is more practical that they have substantially the same dimensions and that they are on substantially the same plane because turbulence does not easily occur in the water flow.

The upstream end of the acidic water outlet 3 is located downstream of the electrolytic flow path 7a on the anode electrode plate 8 side, and the upstream end of the alkaline water outlet 4 is also located downstream of the electrolytic flow path 7a on the cathode electrode plate 9 side. It communicates with the side.

That is, since the upstream end of the acidic water outlet 3 is located on the anode electrode plate 8 side on the downstream side of the electrolytic flow path 7a, the acidic water outlet port 3 flows along the surface (working surface) of the anode electrode plate 8 and is acidified by electrolysis. Alkaline water outlet 4
Is configured so that the upstream end flows along the surface (working surface) of the cathode electrode plate 9 on the downstream side of the electrolytic flow path 7a so that the water alkalized by electrolysis flows out.

In the illustrated embodiment, a gap 18 for recovering acidic water, which opens to the surface (working surface) of the anode electrode plate 8 is provided on the downstream side of the electrolytic flow path 7a, and extends along the surface of the anode electrode plate 8. The acidic water that has flowed through is extracted laterally from the flow in the electrolytic flow path 7a. The extracted acidic water flows into the return passage 15 from the acidic water recovery gap 18, and flows out from the acidic water outlet 3 provided at the downstream end of the return passage 15. In the illustrated embodiment, a collision plate 14 corresponding to approximately half of the electrolytic flow path 7a on the side of the anode electrode plate 8 is provided to facilitate extraction of acidic water. In addition,
The folded flow path 15 is formed in the bulging portion 16 (see FIG. 1) bulging 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 that may occur at the upstream portion of the acidic water outlet 3 is
This is avoided by setting the position of the acidic water outlet 3 at a distance from the downstream end of the anode electrode plate 8 and causing the folded flow path 15 to function as a tank chamber for recovering acidic water of a predetermined capacity.

Further, in the illustrated embodiment, the water flowing along the surface of the cathode electrode plate 9 directly passes through the alkaline water recovery gap 19 formed between the collision plate 14 and the other side container portion 1b. Straight ahead, but the electrolytic flow path 7a
An alkaline water recovery tank chamber (downstream side tank chamber) 17 having a predetermined capacity that communicates with the electrolytic flow path 7a through an alkaline water recovery gap 19 is provided on the downstream side of the alkaline water recovery port 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 path 7a, and has a predetermined capacity to make the local pressure fluctuation uniform. Therefore, in the illustrated embodiment, the influence of the turbulent flow that may occur at the upstream portion of the alkaline water outlet 4 is avoided by the pressure fluctuation equalizing action of the alkaline water recovery tank chamber 17.

As described above, the acidic water recovery tank chamber (folding flow path) 15 and the alkaline water recovery tank chamber (downstream tank chamber) 17 are not necessarily required, but the anode electrode plate 8 and When the area of the cathode electrode plate 9 is made small and it is made compact, it has a remarkable turbulent flow preventing effect. In the illustrated example, one of the anode electrode plate 8 and the cathode electrode plate 9 is used as the acidic water recovery tank chamber (folding flow path) 15 and the other is used as the alkaline water recovery tank chamber 17. Alternatively, the downstream side tank chamber 17 may be used, of course.

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

It is possible to provide an electrolytic cell in which microorganisms do not adhere and the concern about clogging of the diaphragm is eliminated, and which can be used stably for a long period of time.

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

An acidic water recovery gap 18 and / or an alkaline water recovery gap 19 opening in a plane passing through the working surfaces of the anode plate 8 and / or the cathode plate 9 are provided at the downstream side portion of the electrolytic flow path 7a. The boundary layer of the acidic water that has been generated by electrolysis of water and that has flowed along the anode plate 8 and / or the alkaline water that has flowed along the anode plate 8 to the downstream side portion of the electrolytic flow channel 7a is Since it is extracted laterally from the flow in the electrolytic flow path 7a, even if the diaphragm is omitted and the electrode gap is reduced, acidic water and alkaline water are generated without generating turbulent flow in the downstream side portion of the electrolytic flow path 7a. Can be separated, and strong acidic water or alkaline water can be recovered.
