Abstract

PURPOSE:To prevent flow of generated gas to a supply side for alkali ion water or the like by connecting the line on the outlet side of a cathode chamber and an anode chamber to a washing line having a circulation pump and a steam separating means via a pipeline selector valve. CONSTITUTION:Washing liquid flows into a washing line 17 and the washing liquid is circulated together with washing water through an anode chamber 4, a water supply chamber 2 and an anode chamber 5 when pumps 19, 21 are driven. The gas generated during the washing is released from a gas venting tank 18 via a drain line 20 to the outside. The fresh water flows through the chamber 2 and the chamber 5 into the line 17 and is discharged partly through the tank 18 to the line 20 when the pump 21 is stopped and a stop valve 23 is opened upon ending of the washing. The remaining water flows through the pump 19 to the chamber 4 and washes gradually the inside of an electrolytic cell 1.

Description

Detailed Description of the Invention The present invention is a pressure-type continuous electrolyzed water generator that supplies water in a pressurized state, such as when tap water pressure is applied, and continuously produces alkaline ionized water and acidic water. It is related to the device.

In this type of continuous electrolyzed water generation device, a cathode chamber and an anode chamber are separated by a porous partition wall, electrodes are provided in each electrode chamber, and a DC voltage is applied to allow water to flow through the cathode chamber and anode chamber. It is known to perform electrolysis and electroosmosis. In this type of continuous electrolyzer, water supply is controlled on the supply side in front of the electrolytic cell, and when water supply is not required, the pulp on the supply side is closed and monitored. Also, store electrolyzed water, especially alkaline ionized water, in a storage tank.
This type is for use, and water is supplied from the electrolytic cell to the storage tank by the difference in head. Therefore, only when the water level in the storage tank falls below a certain value will a signal be given to the supply valve and water will be supplied to the electrolytic cell.

In addition to requiring a storage tank, this type requires a pump to be installed in the supply line from the storage tank in order to supply water from the storage tank to the destination at the desired water pressure.

Therefore, it is possible to connect the water supply port side of the electrolyzer to a pressure water source such as a water supply, and use that pressure to secure water pressure in the supply line of electrolyzed water, and use a storage tank and pump. , Moreover, the amount of electrolytically generated water can be increased 1. A continuous electrolyzed water generating device was proposed earlier.

In this case, it is necessary to clean the inside of the electrolytic cell from time to time to remove precipitates deposited on the electrodes and the like.

This can be done electrically, such as by using reverse electricity, but there is also a chemical process that uses a cleaning solution and circulates it between the cathode chamber and the anode chamber.

When adopting this chemical treatment method, it is important to note that a chemical reaction caused by the cleaning solution generates a large amount of carbon dioxide gas, which must be discharged. Also, after washing,
This prevents carbon dioxide gas from flowing to the alkaline ionized water supply side or the acidic water supply side.

The present invention has been made based on the above-mentioned circumstances, and includes a cleaning line that can communicate with the cathode chamber and the anode chamber via a control switching valve for the outlet side line of the cathode chamber and the outlet side line of the anode chamber, and In the cleaning line, gases such as carbon dioxide are discharged and circulated for cleaning from time to time, and the generated gas can be discharged without bringing it into the alkaline ionized water supply line or acidic water supply line. The present invention aims to provide a continuous electrolyzed water generating device as described above.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes an electrolytic cell, which has an elongated cylindrical shape and has a water supply chamber 2 at its lower end. The body is divided into the center and the outer circumference by a cylindrical porous partition wall (made of unglazed ceramic or other material that functions as an electropermeable membrane) 3, with the outer circumference serving as a cathode chamber 4 and the center serving as an anode chamber 5. ,
Each is provided with an electrode 6.7. The bipolar chamber 4.5 communicates with the water supply chamber 2 at its lower end. Further, the cathode chamber 4 and the anode chamber 5 are connected at their upper ends to outlet lines 8 and 9, respectively, and the line 8 is connected to a switch means 10 such as a flow switch.
is provided on the outlet side line 9, and the switch means 10 is provided on the outlet side line 9.
An opening/closing valve 1.1 such as a solenoid valve whose opening/closing is controlled by a signal is provided. Further, a pressure gauge or flow meter 12 is provided on the outlet side line 84-, and the pressure or flow rate control valve 13 is controlled by the pressure value or flow rate value of this pressure gauge or flow meter 12, and the opening degree is adjusted. is provided on the line 9. Then, when the bell 14 provided at the tip of the line 8 is opened, the switch means 10
is activated, the on-off valve 11 is opened, and the pressure gauge or flow meter 12 is activated depending on the pressure or flow rate, and the opening of the pressure or flow control valve 13 is automatically adjusted to reduce the pressure on the line 9 side. Alternatively, the flow rate can be controlled. When the collar 14 is closed, the switch means 10 is activated and the on-off valve 11 is closed.

The outlet lines 8 and 9 are provided with conduit switching valves 15, 16 such as motor-driven three-way switching valves, and a cleaning line 17 has both ends connected to its bypass port. The cleaning line 17 includes a gas vent tank 18 as a gas-liquid separation means, and a low-pressure circulation pump 19.
is provided, and a drainage line 20 that also serves as exhaust is connected to the upper part of the gas vent tank 18. Further, a cleaning liquid supply pump 21 is communicated with the suction side of the pump 19 via a reverse IE valve 22.

In the figure, reference numeral 23 is a motor-driven on-off valve provided in a water supply line 24 communicating with a tap water source, and reference numeral 25 is a pump for supplying chemical liquids (minerals, etc.) such as a pulse pump. The water supply chamber 4 is supplied via the check valve 26.
is connected to.

In such a configuration, when the outlet line 8.9 is opened by opening the collar 14, pressure water is supplied to the cathode chamber 4 and the anode chamber 5 with tap water pressure, and the pressure gauge or flow meter 12 and the pressure Alternatively, by the action of the flow rate control valve 13, a supply of acidic water corresponding to the supply amount of alkaline ionized water is achieved, and under this situation, electrolysis is achieved in the electrolytic cell l.

In this case, the direct current application for electrolysis may be applied, for example, by a signal from the switch means IO. During this time, pump 25
The function of mineral replenishment is done.

When the on-off valve 23 is closed, the line switching valves 15 and 16 are simultaneously switched to communicate the cathode chamber 4 and the anode chamber 5 with the cleaning line 17 by means of an appropriate switching control means, and the cathode chamber and anode chamber are connected to the cleaning line 17. A cleaning circuit including a cleaning circuit is configured to be separated from lines to supply destinations of alkaline ionized water and acidic water. Then, when pumps 19 and 21 are driven,
A cleaning liquid flows into the cleaning line 17, and the cathode chamber 4,
A cleaning solution is circulated together with cleaning water through the water supply chamber 2 and the anode chamber 5. The gas generated during this washing is discharged from the degassing tank 18 to the outside via the drainage line 20. Then, when the cleaning is finished (it is recommended to set the time using a timer etc.), the pump 21 is stopped and the on-off valve 23 is opened, and new water is supplied to the water supply chamber 2 and anode chamber 5.
It enters the cleaning line 17 through the degassing tank 8, is partially discharged into the drainage line 20 through the degassing tank 8, and the rest flows into the cathode chamber 4 through the pump 19, gradually washing the inside of the electrolytic cell l with water. be. Once the inside of the electrolytic cell 1 is clean in this way, switch the cathode chamber and anode chamber to the supply destination side of the outlet lines 8 and 9 by switching the pipe switching valves 15 and 16. Normal water production conditions are set by electrolysis and electroosmosis.

In this case, the washing circuit is completely separated from the water generation line by the action of the pipe switching valves 15 and 16.
The gas generated during cleaning is not brought to the alkaline ionized water supply destination. Furthermore, in this embodiment, even if cleaning liquid remains on the delivery side of the pump 21 and flows out into the cleaning line 17 over time, the cleaning line 17 will become independent if the pipe switching valve is switched. There is no risk of it being mixed into the produced water.

In the above embodiment, the cleaning liquid is supplied to the cleaning liquid supply pump 2.
1 into the cleaning line 17, but it may be directly supplied to the water supply chamber 2, the anode chamber 5, or the like.

Furthermore, when the acidic water is not used, the cleaning wastewater may be discharged by providing a pipe that drops to the outlet line 9 side.

As described in detail above, the present invention connects a cleaning line having a circulation pump and a gas-liquid separation means to the outlet lines of the cathode chamber and the anode chamber via a switching valve. As a result, during chemical cleaning, generated gas does not flow to each alkaline ionized water supply, and the generated gas can be discharged outside during the circulation of the cleaning solution and cleaning water. Later, it is often brought to alkaline ionized water suppliers.
