Description

Ultrafine gun generation device using a polling layer {Ultrasonic generation device with pall ring}

The present invention relates to a device for generating ultra-fine bubbles using a polling layer that generates ultra-fine bubbles by dissolving compressed air in treated water.

In general, three methods such as sedimentation, filtration, and flotation are widely used as a method of separating water and suspended matter.

When the specific gravity is similar to that of water and the amount of suspended matter is large or the properties of the suspended matter are viscous, the solid-liquid separation method by flotation is applied more than the solid-liquid separation method by filtration.

As an example, in the prior art, as shown in FIG. 1, compressed air supplied from the compressed air supply 63 is injected and mixed with water having a pressure supplied from the treated water supply pump 61, and then in the microbubble generator 65. Looking at the process of generating compressed water containing microbubbles, a compressed air supply unit 63 in the middle of supplying water with pressure to the treated water supply pump 61 by receiving the required treated water from the treated water supply tank 60 ), the compressed air supplied from the gas-liquid ejector 62 is mixed with water and air, and then supplied to the microbubble generator 65.

Then, when the pressure control valve 72, the pressure maintaining nozzle 73, and the excess air discharge valve 69 are adjusted so that compressed air can be easily dissolved in the treated water inside the microbubble generator 65, microbubbles are required. The air dissolved in the treated water in the unit 74 is generated as microbubbles, and the generated microbubbles are used for necessary purposes.

Thereafter, the pressure gauge 67, the level gauge 71, the excess air discharge valve 69, and the like are adjusted to enable continuous maintenance under the same conditions, and then micro-bubbles are supplied to the subsequent facilities to exert their functions.

However, the microbubble generator operated by such a process requires a long residence time in the microbubble generator 65 to generate microbubbles, as well as the microbubble generator 65 depending on the operation state of the excess air discharge valve 69. ) As the internal operating conditions change, it adversely affects the required microbubbles 74. After a long time, depending on the properties of the dissolved water, a scale is generated on the spray surface of the pressure-maintenance nozzle 73, resulting in normal microbubbles. A problem that hinders the occurrence occurs.
