DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water drop remover for removing water in an ozone gas flow path in an ozone water generation apparatus for mixing ozone gas and raw water to generate ozone water.

[0002]

2. Description of the Related Art Conventionally, an ozone water generator has been used for applications such as sterilization, sterilization, deodorization, etc., utilizing the oxidizing action of ozone. Ozone water generator (1)
For example, as shown in FIG. 4, ozone gas generated by an ozone generator (ozonizer) (2) is mixed with raw water by an ejector (3) to generate ozone water, but is not sufficiently dissolved in ozone water. Ozone gas is separated from ozone water by a gas-liquid separator (4). The ozone water from which the ozone gas has been separated by the gas-liquid separator (4) is used for sterilization, etc., while the waste ozone gas is used in the catalytic device (5).
Is decomposed by a catalyst, reduced to oxygen, and discharged into the outside air. The ejector (3) is for mixing and dissolving ozone gas in the form of fine bubbles in the flow of raw water.

[0003]

By the way, in the ozone water generating apparatus (1) having the above-mentioned structure, in a transient operation state in which, for example, the supply and the stop of the ozone water are switched, the ozone generator (1) is supplied from the ejector (3). 2) Water may flow backward. In such a case, there arises a problem that ozone is not generated in the ozone generator (2) or the ozone generator (2) breaks down.

[0004] Water droplets may also be contained in the waste ozone gas from the gas-liquid separator (4). In such a case, water flows into the catalyst device (5), and the life and performance of the catalyst are reduced. Problems, such as a decrease in the power consumption or a risk of failure.

On the other hand, Japanese Unexamined Patent Application Publication No. 10-165794
In the official gazette, the above-mentioned ejector (3)
A waterdrop remover that prevents backflow of water into the water is disclosed.
In this water drop remover, a drain hole is formed in the lower surface of a water storage part for temporarily storing water, and an opening / closing valve for closing the drain hole from below is provided. The on-off valve is normally urged upward to close the drain hole, and when a certain amount of water accumulates, the pressure opens the drain hole to discharge the water.

However, this structure tends to be complicated because it is necessary to apply an upward biasing force to the on-off valve to close the drain hole. Further, since the urging means is required, the mechanism including the urging means is likely to cause a failure, and if a failure occurs, it is impossible to prevent water from flowing into the ozone generator or the like. I will.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to surely remove water flowing in an ozone gas flow path with a water drop remover having a simple structure.

[0021] A seventh solution taken by the present invention is:
In any one of the first to sixth solving means, the drain port (15) of the main body (11) allows the water to be discharged from the main body (11), while allowing the water to be discharged to the main body (11). A check valve (16) for inhibiting the inflow of air is connected.

With this configuration, the water drop remover (10A, 1
0B), when the float (12) rises and the float (12) rises, water is discharged from the main body (11), while when there is no water in the main body (11), air enters through the drain port (15). Or not.

An eighth solution taken by the present invention is:
In the ozone water generator (1) for generating ozone water by mixing ozone gas with raw water, the first ozone gas flow path (P1, P2) for supplying ozone gas to a mixing section (3) with raw water is provided with the first ozone gas.

Further, the first solution has a configuration provided with an on-off valve using a float (12), and does not include a mechanism using an urging means. Ozone gas flow path (P1, P2, P6,
P7) Water flow can be almost certainly prevented.

According to the second and third solutions, the lower end portion (12a) of the float (12) is shaped so that the cross-sectional area decreases from the upper side to the lower side, so that the water droplet remover ( When water accumulates in the main body (11) of the floats (10A, 10B), buoyancy is reliably generated in the float (12), and the drain port (15) is opened.

Next, the water droplet remover used in the present embodiment
The configuration of (10A, 10B) will be specifically described.

As described above, the first water droplet remover (10A) is provided in the ozone gas pipe (P1, P2), and the second water droplet remover (10A) is provided.
(10B) is provided in the waste ozone gas pipe (P6, P7). That is, both of the water droplet removers (10A, 10B) are provided in the ozone gas flow paths (P1, P2, P6, P7). The water drop removers (10A, 10B) have the same configuration, and are configured to remove water drops flowing in these ozone gas flow paths (P1, P2, P6, P7).

As shown in FIG. 2, the water drop remover (10A, 10B) includes a vertical cylindrical container-shaped main body (11) and a float (12) housed in the main body (11). Have. Main unit (11)
An ozone gas inlet (13) is formed on the upper surface of the device, and an inflow ozone gas pipe (P1) (waste ozone gas pipe (P6)) is connected to the ozone gas inlet (13). An ozone gas outlet (14) is formed in the upper part of the side surface of the main body (11) .The ozone gas outlet (14) has an ozone gas pipe (P2) on the outflow side.
(Waste ozone gas pipe (P7)) is connected. further,
A drain port (15) is formed on the bottom surface of the main body (11), and a check valve (16) and a drain pipe (17) are connected to the drain port (15). The check valve (16) is configured to allow discharge of water from the main body (11), while preventing air from entering the main body (11).

The float (12) is formed of a material having a specific gravity smaller than that of water. This float (12) is
1) It is formed in a cylindrical shape having an outer diameter slightly smaller than the inner diameter of the main body (11) so as to move up and down in the inside. The float (12) closes the drain port (15) at the lower limit position of the movable range in the main body (11), and at the upper limit position of the movable range, the ozone gas pipe (P1) on the inflow side (waste ozone gas). The pipe (P6) is configured to be in contact with the lower end face and to close the ozone gas inflow port (13). In this configuration, the float (12) and the drain port (15) constitute an on-off valve.

The float (12) is formed in a stepped shape having a small diameter at the lower end (12a). This float (1
The lower end (12a) of 2) is made of a material such as fluororubber, and the rubber is brought into close contact with the bottom surface of the main body (11) to seal the drain port (15). Also float
A fluororubber material (not shown) is also adhered to the upper end of (12), and the fluororubber material is supplied to the inflow side ozone gas pipe (P1) (waste ozone gas) at the upper limit position of the movable range of the float (12). The ozone gas inlet (13) is reliably closed by being in close contact with the lower end surface of the pipe (P6).

The upper end and lower end (12) of the float (12)
a) is not limited to fluororubber, and may be formed using other rubbers or resins.
Adhesion to the bottom surface of (11) and the lower end surface of the pipe (P1, P6) can be increased.

-Operating operation- Next, this ozone water generating apparatus
The operation during the operation (1) will be specifically described.

First, during normal operation, in the ozone generator (2), ozone gas is generated by electric discharge at an electrode plate provided in the flow path of the source gas. On the other hand, the ejector
(3) is supplied with pressurized raw water, and when the raw water passes through the throttle of the ejector (3), ozone gas is sucked from the ozone generator (2). The ozone gas flows into the main body (11) of the first water drop remover (10A) from the inflow side ozone gas pipe (P1) as indicated by an arrow in FIG. 2, and the lower end (12a) of the float (12) is moved to the main body. While being pressed against the bottom surface of the part (11), it flows out of the outflow-side ozone gas pipe (P2) and is sucked into the ejector (3). Here, since the lower end (12a) of the float (12) is made of fluorine rubber, the lower end (12a) is
5) Adhere around. Therefore, the operation of inflowing ozone gas flowing out of the ozone gas outlet port (14) without flowing to the drain port (15) is guaranteed. In addition, since the check valve (16) is provided in the drain port (15), the float (12) does not rise due to the suction force of the ozone gas from the ejector (3) at this time, and the air is sucked. There is no danger.

In the ejector (3), the ozone gas is mixed with the raw water in the form of fine bubbles in the form of fine bubbles, and is dissolved to produce ozone water. The ozone water generated by the ejector (3) is supplied from the ozone water pipe (P4) to the gas-liquid separator (4). The gas-liquid separator (4) removes excess ozone gas that is not dissolved in ozone water, and supplies excess ozone gas that does not contain ozone gas to the ozone water supply pipe (P5) for use such as sterilization while using waste ozone gas. From the waste ozone gas pipes (P6, P7) provided with the second water droplet remover (10B) to the ozone decomposition catalyst device (5).

In the second water droplet remover (10B), as in the first water droplet remover (10A), as shown by the arrow in FIG.
The waste ozone gas that has flowed into the (11) presses the fluoro rubber at the lower end (12a) of the float (12) against the bottom surface of the main body (11) to bring the fluoro rubber into close contact with the periphery of the drain port (15). so,
The waste ozone gas is supplied to the ozone decomposition catalyst device (5) while reliably preventing the waste ozone gas from flowing out from the drain port (15). In the ozone decomposition catalyst device (5), ozone gas is reduced to oxygen under a catalyst, and the oxygen is released into the outside air as exhaust gas.

On the other hand, in the first water drop remover (10A),
In a transitional operation state in which the supply and the stop of the ozone water are switched, water may flow into the main body (11) and accumulate.

In such a case, when water flows into the main body (11) of the first water drop remover (10A), the float (12) is initially at the lower limit position of the movable range as shown in FIG. Drain outlet (1
5) Blocks the water so that the water floats on the bottom of
It gradually accumulates from the gap between the small diameter portion of (12).
Then, as shown in FIG. 3, when a certain amount of water accumulates in the flow of the solid arrow from the ozone gas pipe (P2), the float (12)
Rises according to the water level, the drain port (15) is opened, and the water is discharged. Therefore, in the case where the water continues to flow into the water drop remover (10A), the operation of discharging the water after a certain amount of water accumulates in the water drop remover (10A) is repeated. When the operation returns to the normal operation and the ozone gas is sucked from the ejector (3), the float (12) is pushed down by the pressure of the ozone gas, the water is almost completely discharged, and the state returns to the state shown in FIG.

On the other hand, in the second water drop remover (10B),
During normal operation, water may flow in from the gas-liquid separator (4).

When water flows into the main body (11) of the second water drop remover (10B), the float (12) is initially set at the lower limit as shown in FIG. 2 as in the first water drop remover (10A). Since it is in the position and closes the drain port (15), water gradually accumulates from the gap between the bottom surface of the main body (11) and the small diameter portion of the float (12). When a certain amount of water accumulates in the flow indicated by the dashed arrow in FIG. 3, the float (12) rises, and the drain (1)
5) is opened and water is discharged. As described above, in the second water droplet remover (10B), when water accumulates to some extent in the main body (11) during the normal operation, the operation of discharging the water is repeatedly performed.

-Effects of Embodiment- According to the present embodiment, a water drop remover is provided by using the float (12).
(10A, 10B) is discharged when water accumulates in the main body (11) of the main body (11).
It does not flow over the water drop remover (10A, 10B) in the inside. For this reason, water flows back to the ozone generator (2),
Does not enter the ozone decomposition catalyst device (5). Therefore, it is possible to reliably prevent ozone gas from being generated in the ozone generator (2) or to prevent the ozone generator (2) from failing, and to reduce the performance or life of the catalyst device (5) or to reduce the failure. Can be reliably prevented. As described above, according to the present embodiment, it is possible to reliably prevent a failure of each part of the ozone water generation device (1) and a decrease in performance.

The water drop remover (10A, 10B) of the present embodiment
Has an opening / closing valve using a float (12) and does not have a mechanism using a biasing means or the like, so there is little risk of failure. Therefore, it is possible to almost certainly prevent the backflow of water with a simple structure.

Further, since the lower end (12a) of the float (12) has a stepped shape, when a certain amount of water accumulates in the main body (11) of the water drop remover (10A, 10B), the float (12) Buoyancy is reliably generated, and the drain port (15) is opened. Therefore, water can be discharged before the water level in the main body (11) rises more than necessary.

On the other hand, even if the water in the main body (11) is not discharged for some reason, when the float (12) rises to the upper limit position, the ozone gas inlet (13) is closed. (Refer to the phantom line in Fig. 3) Even in such a case, water flows through the ozone gas flow path (P1, P7) and enters the ozone generator (2) or the ozone decomposition catalyst device (5). Can be reliably prevented. In particular, the first water drop remover (1
0A), the backflow water into the main body (11) floats (1
2) Fluoro rubber material at the upper end of the inflow side ozone gas pipe (P1)
Pressing against the lower end surface of these to make them adhere to each other, so that the backflow water does not flow to the ozone gas inlet (13),
It is surely discharged from the drain (15).

[0059]

Other Embodiments of the Invention The present invention may be configured as follows with respect to the above embodiment.

For example, in the above embodiment, the lower end (12a) of the float (12) has a stepped shape.
The lower end portion (12a) may have another shape such as a tapered shape as long as the cross-sectional area decreases from the upper side to the lower side.

In the above embodiment, the check valve (16) is provided at the drain port (15) to prevent air from being sucked from the drain port (15) when ozone gas is sucked from the ejector (3). When the ozone gas is sucked, the drain (1
If 5) can be reliably closed, the check valve (16) may not be necessarily provided.

The main body (11) of the water drop remover (10A, 10B)
The specific shape and the like of the float (12) are merely examples, and can be changed as appropriate.
