Description

Apparatus for Dissolving Oxygen Using Bubble}

The present invention relates to an oxygen dissolving apparatus using bubbles, and more particularly, to an oxygen dissolving apparatus using bubbles for effectively dissolving oxygen in water.

In general, a dissolving device for dissolving gas is a device used to dissolve gas such as oxygen or ozone in a waste water or a liquid such as water in a wastewater treatment plant, a water treatment plant, a water purifier, a nutrient solution or aquaculture farm for hydroponic cultivation. The treatment is used to increase the dissolved oxygen (DO) content in water.

It is necessary to keep the amount of dissolved oxygen above a predetermined value not only to preserve the life of fish or other aquatic organisms, but also to suppress the formation of odorants or organic substances. In addition, the biochemical oxygen demand (BOD) is determined by the amount of oxygen required for the biological process of destroying organic matter in water. Say. Gas-dissolving devices are extremely useful for increasing the amount of dissolved oxygen, and they are of great value especially in the case of high biochemical oxygen demand.

The gas dissolving device is a device used to dissolve gases such as oxygen or ozone in a liquid such as waste water or water in a wastewater treatment plant, a water treatment plant, a water purifier, a nutrient solution for hydroponics, aquaculture farm, etc. It is mainly used for the purpose of improving gas dissolution rate such as oxygen or ozone.

Such gas dissolving devices are roughly classified into two types: air diffusion type and mechanical type. The air diffusion type gas dissolving device has a structure in which air or pure oxygen is introduced into the water through a submersible porous diffusion member or a nozzle, and the mechanical gas dissolving device has a structure in which water is dissolved in the atmosphere by disturbing water.

The mechanical gas dissolving unit is further subdivided into a water gas dissolving unit and a turbine gas dissolving unit. The water gas dissolving device is designed to drastically change the contact area between air and water by introducing water in the water by disturbing water with a submerged or partially submerged impeller. In addition, the turbine gas dissolving device uses a rotating impeller installed at a predetermined depth below the surface of the treated water, and a vent pipe is supported on the coaxial with the impeller to supply external air to the water around the impeller.

Referring to the drawings, the oxygen dissolving apparatus 100 using the bubble is installed in the first body 22 and the first body 22 having an internal space 28 and partitions the internal space 28 in the vertical direction. Oxygen entrapment spaces are formed between the first partition plates 24a, 24b and 24c and the first partition plates 24a, 24b and 24c to form the oxygen encapsulation space between the first partition plates 24a, 24b and 24c and the water surface. Pressure tank having a first induction discharge pipe 26 for guiding the upper water to the lower side and a first discharge pipe (30) installed in the lower portion of the first body 22 to discharge the water in the interior space (28) 20, a first water supply pipe 10 having a nozzle 12 so as to spray water on one side of the upper side space portion partitioned by the first partition plates 24a, 24b, 24c, and a first water supply pipe. An oxygen supply pipe 50 is connected to the first water supply pipe 10 to piggyback oxygen on the water flowing at 10.

The first water supply pipe 10 is connected to the water intake tank 14, and the water withdrawn from the water intake tank 14 is supplied to the pressure tank 20 through the first water supply pipe 10. The first water supply pipe 10 is provided with a pump 18 for water supply, and a first valve 16 for adjusting the water supply is installed. The first water supply pipe 10 penetrates into the pressure tank 20 from the intake tank 14 and extends into the pressure tank 20. The first water supply pipe 10 extending into the pressure tank 20 has a nozzle 12 and sprays water to the upper side space partitioned by the first partition plates 24a, 24b, and 24c. When the first water supply pipe 10 sprays water, the sprayed water falls downward while hitting the upper wall surface by spraying water on one side of the upper space part. When the water hits the upper wall, the water is dispersed and the contact area with the air inside is widened, and oxygen can be supplied to the water to dissolve the oxygen.

The oxygen supply pipe 50 is installed in connection with the first water supply pipe 10 to piggyback oxygen on the water flowing in the first water supply pipe 10. When connecting the oxygen supply pipe 50 and the first water supply pipe 10 is installed by using a venturi tube. Oxygen introduced through the oxygen supply pipe 50 and water introduced through the first water supply pipe 10 are mixed by the venturi tube to dissolve oxygen in the water. The oxygen supply pipe 50 may be formed by connecting at least one of the oxygen generator 56, the high pressure oxygen or the oxygen tank 54 into which the liquefied oxygen is injected to receive oxygen. A second valve 58 and auxiliary valves for regulating the supply of oxygen may be installed in the oxygen supply pipe 50 and the branch pipe 58 connecting the oxygen generator 56 or the oxygen tank 54 connected thereto.

The pressure tank 20 has an inner space 28 and the inner space 28 is partitioned by the first partition plates 24a, 24b, and 24c. The first partition plates 24a, 24b, and 24c have a first induction discharge pipe 26 that guides the upper water downward to form an oxygen entrapment space between the water surface and the first partition plates 24a, 24b, and 24c. Have The first partition plates 24a, 24b, and 24c are formed to have a size corresponding to the inner surface of the first body 22 so that the upper water is discharged only to the first induction discharge pipe 26. The first partition plates 24a, 24b, and 24c are provided so that the first induction discharge pipes 26 cross each other.

When the first water supply pipe 10 sprays water onto one side wall of the upper partition space partitioned by the first partition plates 24a, 24b, and 24, the water strikes the wall surface and falls to the first partition plate 24a. . As the water descends into the first partition plate 24a and is dispersed due to the collision with the first partition plate 24a, the contact area with oxygen is widened. Water can dissolve oxygen when the contact area with oxygen increases. Water lowered to the first partition plate 24a flows into the first partition plate 24b below through the first induction discharge pipe 26. When the water is filled in each compartment, the end of the first induction discharge pipe 26 is submerged in water and the first induction discharge pipe 26 from the upper side first partition plate 24a to the first partition plate 24b below. When water descends through the vortex occurs. An oxygen immersion space is formed between the first partition plates 24a, 24b, and 24c and the surface of the water, and when vortices occur, oxygen and water in the oxygen immersion space come into contact with each other to dissolve oxygen. Water introduced into the pressure tank 20 passes through the pressure tank 20 to form a micro bubble. Oxygen can be dissolved using micro bubbles to increase the amount of dissolved oxygen in the water.

Water lowered to the lower portion of the first body 22 is discharged through the first discharge pipe 30 installed in the lower portion of the first body 22. The pressure tank 20 is made of synthetic resin to prevent corrosion. Preferably it is made of PPC (Poly Propylene Copolymer) in the synthetic resin.

Here, the auxiliary pressure tank 40 may be further provided to once again dissolve the water discharged through the first discharge pipe 30 with oxygen.

The auxiliary pressure tank 40 divides the second main body 42 with the first discharge pipe 30 installed therein and has an inner space, and is divided into the second main body 42 and the inner space 48 in the vertical direction. Oxygen entrapment spaces are formed between the second partition plates 44a, 44b, 44c and the second partition plates 44a, 44b, 44c to form the oxygen compartment space between the second partition plates 44a, 44b, 44c and the water surface.
