Description

Description: TECHNICAL FIELD The present invention relates to a production apparatus for continuously producing high-concentration water of a gas such as ozone.

BACKGROUND OF THE INVENTION Recently, demands for ozone water, oxygen-dissolved water, and the like have been increasing. Ozone water is dissolved in, for example, the sterilization of circulating water in a pool and has various advantages as compared with the conventional chlorine-based disinfectants.

Oxygen gas-dissolved water has recently been used for preserving the freshness of fresh vegetables, and it is predicted that the use of oxygen-gas-dissolved water will increase in the same manner as ozone water.

In any case, the higher the concentration of the dissolved gas, the higher the respective effects.

Also, when the high-concentration gas-dissolved water is diluted and used, its concentration can be easily controlled.

[Problems to be Solved by the Invention] However, it is difficult to continuously produce the single gas-dissolved water at a high concentration, and such an apparatus has not been tried yet.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an apparatus capable of continuously producing high-concentration dissolved water of a single gas such as ozone.

[Means for Solving the Problems] To this end, the present invention provides an exhaust pipe having an exhaust device and a water supply pipe having a water supply valve in the upper part, and a discharge pipe having a pump and a discharge valve in the lower part. A pair of deaeration cylinders having the above-mentioned structure is provided, and both the discharge pipes are connected to a common discharge main pipe, and a means for press-fitting gas into the discharge main pipe is provided.

[Embodiment] Hereinafter, a single dissolved gas high concentration water producing apparatus according to an embodiment of the present invention will be described. FIG. 1 is an explanatory view of an ozone high-concentration water producing apparatus. In the figure, 1a, 1b is a pair of degassing cylinders, 2a, 2b is a water supply pipe provided above the degassing cylinders 1a, 1b, is disposed from the outside of the degassing cylinders 1a, 1b to the inside. Sprinkling nozzles 3a and 3b are attached upward at the tip.

4a, 4b are water supply pipes 2 projecting outside the deaeration cylinders 1a, 1b
The water supply valves provided in a and 2b are always set to a predetermined opening. The base ends of the water supply pipes 2a and 2b are connected to each other, and the water supply main pipe 5 is connected to the connection part. The water supply valves 4a and 4b adjust the amount of water supply in a well-balanced manner, and water can be simultaneously supplied from the water supply main pipe 5 to the deaeration cylinders 1a and 1b from the water supply nozzles 3a and 3b via the water supply pipes 2a and 2b. I have.

Reference numerals 6a and 6b denote pumps provided below the deaeration cylinders 1a and 1b for alternately sucking and reducing the pressure of water in the deaeration cylinders 1a and 1b and discharging the water. 7a, 7b is a discharge valve provided on the discharge side of the pumps 6a, 6b, 8a, 8b is a discharge pipe provided on these discharge valves 7a, 7b, these discharge pipes 8a, 8b are connected to each other, and at the connection part The discharge main pipe 9 is connected. Where the pump 6a
The discharge valve 7a is linked with the discharge valve 7a so that the discharge valve 7a opens when the pump 6a operates and closes when the pump 6a stops. Similarly, the pump 6b and the discharge valve 7b are interlocked.

Reference numeral 10 denotes a gas press-fitting device provided in the discharge main pipe 9, and reference numeral 11 denotes a gas supply pipe connected to the gas press-fitting device 10. The other end of the gas supply pipe 11 is connected to a gas supply source 12. The washing end of the discharge main pipe 9 extends to the ozone water demand side 13. Note that it is effective to use a device that supplies bubbles as finely as possible as the gas injection device 10.

Exhaust pipes 14a and 14b are provided at upper end portions of the deaeration cylinders 1a and 1b, respectively, and are provided with exhaust devices 15a and 15b, respectively. As the exhaust devices 15a and 15b, for example, the present applicant has
The deaerator provided in 3447 may be used. That is, the exhaust system is provided with a valve which is always forcedly opened and closed when the pressure in the deaeration cylinder is reduced, and a valve which is closed when the water is full.

Next, the operation of the present embodiment will be described. First, water supplied to the water supply main pipe 5 is supplied through the water supply main pipe 5 and the water supply pipes 2a and 2b from the watering nozzles 3a and 3b into the deaeration cylinders 1a and 1b, and the deaeration cylinders 1a and 1b are supplied. Fill the inside with water and make it start.

When the pump 6a operates, the discharge valve 7a opens at the same time,
The water in the degassing cylinder 1a is degassed under reduced pressure by the suction action of the pump 6a and discharged to the discharge main pipe 9. Then, ozone gas is constantly injected from the gas supply source 12 into the discharge main pipe 9 to become high-concentration ozone water and supplied to the demand side 13.

At this time, the opening degrees of the water supply valve 4a and the discharge valve 7a are set in advance so that the pressure in the deaeration cylinder 1a is reduced in relation to the suction force of the pump 6a. In this case, the amount of water supplied from the watering nozzle 3a is slightly smaller than the amount of water discharged from the discharge pipe 8a.

When the pump 6a operates, the degassed gas stays in the upper part of the degassing cylinder 1a, so that the water level in the degassing cylinder 1a gradually decreases.

When the pump 6a is operating, the pump 6b is stopped, and the discharge valve
Since 7b is closed, the inside of the degassing cylinder 1b is on standby for being filled with water.

The water supplied into the degassing cylinder 1a in this manner is degassed and flows from the discharge pipe 8a to the main discharge pipe 9, where the ozone gas is injected into the gas injection device 10 to become ozone water. In this case, the ozone gas is dissolved at a high concentration because the other gas has been degassed.

As described above, high-concentration ozone water is generated and supplied to the demand side 13.

Then, when the pump 6a is stopped when the water level in the deaeration cylinder 1a drops to a predetermined position, the valve 7a is also closed at the same time. In the degassing cylinder 1a, the water level in the degassing cylinder 1a gradually rises since water is continuously supplied from the water spray nozzle 3a via the water supply pipe 2a, and the exhaust device 15a is opened and stays in the degassing cylinder 1a until the pressure approaches the atmospheric pressure. The exhausted gas is exhausted. When the exhaust is completed and the water is full, the exhaust device 15a operates and the exhaust port is automatically closed.

At the same time when the pump 6a stops, the pump 6b and the discharge valve 7b
Operates, and the same operation as the deaeration performed earlier in the deaerator 1a is now performed in the deaerator 1b, and the deaerated water is discharged until the water level in the deaerator 1b drops to a predetermined position. The high-concentration ozone water is circulated to the main pipe and continuously supplied to the demand side 13.

During this time, the water level in the degassing cylinder 1a rises and is restored, and the system is in a full state and waits for the next step.

The above operations are alternately performed between the deaeration cylinders 1a and 1b, and the high-concentration ozone water is continuously supplied.

The control of the water level in the deaeration cylinders 1a and 1b is automatically performed by operating a pump using a water level sensing electrode rod or a timer and opening and closing a valve, but the method is not limited to a specific method.

[Effects of the Invention] According to the present invention, it is possible to continuously produce single-gas high-concentration dissolved water such as ozone.
