モニタリングすることができる。 Next, the operation of the atmospheric salinity absolute value measuring device having the above configuration will be explained. First, when the valve 3 of the water supply section is opened, ultrapure water is supplied into the closed water tank 1 through the water supply pipe 2. When the flow switch 4a operates, the valve 3 of this water supply section is closed, and the supply of ultrapure water to the sealed water tank 1 is stopped. Therefore, the sealed water tank 1 is filled with a certain amount of ultrapure water. Next, when the valve 8 of the water supply section opens and the pump 5 operates, the atmosphere is sent to the bubble generation section 10 through the air supply pipe 6 at a constant flow rate for a certain period of time, so that the atmosphere is converted into ultrapure water in the sealed water tank 1. Bubble. When this bubbling ends, the valve 8 is closed, and the valve 12 of the discharge section is opened, and the ultrapure water in the sealed water tank 1 is drained at a constant flow rate through the drain pipe 11 using the position button. . Therefore,
The Na + ion concentration meter 13 measures the concentration of ultrapure water in the drained ultrapure water.
Measure the Na + ion concentration. During this bubbling, the valve 17 is opened, and a constant amount of ultrapure water is flowed through the background water supply pipe 16.
A background value is measured by the Na + ion concentration meter 13. Then, the valve 15 is opened, and ultrapure water is sent into the closed water tank 1 through the pipe 14, and the inside of the closed water tank 1 is cleaned. By repeating the above operations, the absolute amount of salt in the atmosphere can be continuously monitored.
しかしながら、従来の大気塩分濃度絶対値測定
装置はバブル発生部から発生する気泡が大きいた

可能性がある。また、吸引時の流量は一定である
ため、大気の状態によつて、同じ塩分濃度でも異
なつた値を示すなどの欠点があつた。 However, in the conventional atmospheric salinity concentration absolute value measuring device, the bubbles generated from the bubble generating part are large, so the specific surface area where air and ultrapure water come into contact becomes small. For this reason, salt in the atmosphere may not be sufficiently dissolved. In addition, since the flow rate during suction is constant, there are drawbacks such as the same salinity concentration exhibiting different values depending on atmospheric conditions.

Therefore, an object of the present invention is to provide an apparatus for measuring the absolute value of atmospheric salinity concentration, which enables accurate measurement by reducing the size of bubbles generated from a bubble generating part and increasing the specific surface area between air and ultrapure water. It is something to do.

る。 In order to achieve these objectives, the present invention includes a sealed water tank that stores a certain amount of ultrapure water, a bubbling generating section that turns air into bubbles and sends them into the ultrapure water, and a system that reduces the size of the bubbles generated from this bubbling generating section. In order to do this, there is a mesh provided in this bubbling generating section, a means for forcibly sending atmospheric air into this bubbling generating section for a certain period of time, and after bubbling for a certain period of time, the ultrapure water in the sealed water tank is discharged. It is equipped with means and a Na + ion concentration meter for analyzing the Na + ion concentration of a certain amount of the discharged ultrapure water, and is capable of continuously measuring the absolute value of the salt concentration in the atmosphere. This will be explained in detail below using examples.

FIG. 2 is a block diagram showing an embodiment of the atmospheric salinity absolute value measuring device according to the present invention. In the figure, reference numeral 18 denotes a mesh inserted into the bubble generating section 10, a detailed partial perspective view of which is shown in FIG.

きる。 Next, although it goes without saying that the atmospheric salinity absolute value measuring device having the above configuration operates in the same manner as shown in FIG. I can do it. Therefore, the specific surface area where air and ultrapure water come into contact can be increased. Also,
At this time, by making the suction speed the same as the atmospheric flow velocity using the bubble 8 and the flow meter 9, a stable value can always be obtained even if the atmospheric conditions vary.

In this case, the amount of air supplied is measured by a flow meter and can be regulated with a valve 9. Furthermore, it goes without saying that the air supply time can be changed by setting the timer. Moreover, although the mesh 18 is provided on the outside of the bubble generating section 10 in the above description, it is of course possible to provide it on the inside.
