Description

  The present invention relates to a mixing device for mixing a fluid with a liquid.

In recent years, in fields such as chemical industry and biological industry, bubbles having a diameter of 100 μm or less called fine bubbles may be generated in a liquid. The finely divided air bubbles remain in the water for a long time without rising to the water surface and bursting. Then, various functions can be added to the liquid by efficiently mixing, diffusing, and dissolving the bubbles in the liquid.
Conventionally, for example, when performing biological treatment with activated sludge in sewage treatment, oxygen is mixed with water to be treated (sewage) in an aeration tank in order to supply oxygen to activated sludge (microorganisms) that decomposes organic matter. ing.

  And in various water treatments, there are some which have provided the mixing device for mixing gas to-be-processed water in a tank. As such a mixing apparatus, there is an apparatus in which an injection passage is opened to the inner surface of the storage chamber, and a discharge passage is opened to the other inner surface facing the inner surface (see, for example, Patent Document 1).

In such a mixing apparatus, after the water to be treated and the gas are injected from the injection passage into the storage chamber and the water to be treated and the gas are mixed in the storage chamber, the treated water (mixture) in the storage chamber is discharged from the discharge passage, for example It is discharged into the aeration tank.
When the water and gas to be treated are injected from the injection passage into the storage chamber, the cavitation effect causes the gas to be finely bubbled. Thus, the amount of gas dissipated from the water to be treated to the atmosphere can be reduced by microbubbling the gas in the water to be treated.

  In the above-described conventional mixing apparatus, when the water and gas to be treated are injected from the injection passage into the storage chamber, the water and gas to be treated swirl in the storage chamber. At this time, it is preferable to increase the oxygen concentration of the treated water by sufficiently swirling the treated water and the gas in the storage chamber to bring the treated water and the gas into contact with each other.

In order to mix the fluid such as oxygen well with the liquid such as the water to be treated, it is preferable that the fluid and the fluid be greatly swirled in the storage chamber to greatly disturb the behavior of the fluid and the fluid.
However, as in the conventional mixing apparatus, when the inlet and outlet are open on the opposite two sides in the storage chamber, the liquid and fluid are easily ejected from the outlet without being caught in the vortex flow. There's a problem. In addition, in the conventional mixing apparatus, the piping for injection and discharge protrudes to both sides of the apparatus, which causes a problem of increasing the installation space.

  An object of the present invention is to solve the above-mentioned problems, and to provide a mixing device capable of efficiently mixing a liquid and a fluid in a space-saving manner.

  In order to solve the above-mentioned subject, the present invention is a mixing device for mixing a fluid with a fluid, and is provided with a processing tank which has a storage chamber in which a mixture of the fluid and the fluid is stored. On the inner surface of the storage chamber, an inlet of an injection passage for injecting the liquid and the fluid into the storage chamber is opened, and an outlet of a discharge passage for discharging the mixture from the storage chamber is provided. It is open. The inlet is disposed on a first inner surface of the storage chamber, and the outlet is disposed on an inner surface other than the second inner surface facing the first inner surface of the storage chamber.

  In the mixing apparatus of the present invention, the liquid and the fluid (gas or liquid) injected into the storage chamber from the inlet on the first inner surface abut the second inner surface and the flow changes greatly. Then, the liquid and the fluid are largely swirled in the storage chamber, and then discharged from the discharge port disposed on the surface other than the second inner surface.

  Thus, in the mixing device of the present invention, the inlet and the outlet are open on two opposite sides. In other words, since the outlet is open on the inner surface other than the second inner surface facing the first inner surface where the inlet is open, the liquid and fluid injected into the storage chamber do not get caught in the vortex, and from the discharge passage The problem of being easily discharged can be reduced. As a result, the liquid and fluid flow in a long path in the reservoir chamber while being involved in the vortex flow, and the behavior of the liquid and fluid can be greatly disturbed, so that the liquid and the fluid can be well mixed.

  Further, in the mixing apparatus of the present invention, the piping of the injection path and the piping of the discharge path do not protrude to both sides of the processing tank, so the installation space can be reduced and the freedom of layout can be enhanced.

  In the mixing apparatus described above, the inlet and the outlet are preferably disposed on the first inner surface. In this configuration, two vortices are formed in the reservoir, so that the liquid and the fluid can be well mixed.

  In the mixing apparatus described above, when the first inner surface is the inner surface of the side portion of the storage chamber, the inlet may be disposed at the upper portion of the first inner surface and the outlet may be disposed at the lower portion of the first inner surface.

In the mixing device described above, when the first inner surface is the inner surface of the side of the storage chamber, the inlet and the outlet may be disposed below the first inner surface.
In this configuration, the liquid and fluid injected into the reservoir from the inlet will form an upper vortex and a lower vortex. At this time, the momentum of the upper vortex is increased by the buoyancy of the fluid, so that the fluid and the fluid can be well mixed.

  In the mixing device described above, when the inlet is disposed above the outlet, the liquid and the fluid flow from the upper vortex to the lower vortex and are discharged from the outlet. Can be mixed well.

In the mixing apparatus described above, when the first inner surface is the inner surface of the side portion of the storage chamber, the inlet is disposed at the lower portion of the first inner surface, and the discharge port is the inner surface of the top of the storage chamber. It is preferable to arrange in.
In this configuration, the fluid and the fluid are greatly swirled in the storage chamber, and the buoyancy of the fluid increases the momentum of the vortex so that the fluid and the fluid can be well mixed.

In the mixing apparatus described above, when the first inner surface is the inner surface of the top of the storage chamber, the discharge port is preferably disposed below the inner surface of the side portion of the storage chamber.
In this configuration, the fluid and the fluid can be well mixed because the fluid and the fluid are greatly swirled in the storage chamber.

In the mixing device described above, when the first inner surface and the second inner surface, which face each other, and the third inner surface and the fourth inner surface, which face each other are arranged in a square tube shape on the inner surface of the storage chamber Preferably, a distance between the first inner surface and the second inner surface is longer than a distance between the third inner surface and the fourth inner surface.
The distance between the first inner surface and the second inner surface is preferably between 2 and 4 times the distance between the third inner surface and the fourth inner surface, and 2.5 times More preferably, it is between 3.5 and 3.5 times.

In this configuration, the storage chamber is a flat space. Then, when the storage chamber is formed in a flat space, the direction vector of the vortex flow becomes two-dimensional. Thereby, the vortex formed in the storage chamber can be stabilized, so that the liquid and the fluid can be well mixed.
The degree of flatness of the storage chamber can also be adjusted by overlapping the adjustment plate on the inner surface of the storage chamber.

  The mixing device of the present invention can mix the liquid and the fluid well and can reduce the installation space, so that the liquid and the fluid can be efficiently mixed in a space-saving manner.

Problem can be reduced. As a result, the water to be treated and oxygen flow along a long path in the storage chamber 10, and the behavior of the water to be treated and oxygen in the storage chamber 10 is greatly disturbed, whereby the water to be treated and oxygen are sufficiently Because of contact, the water to be treated and oxygen can be mixed well.
Further, since the storage chamber 10 is a flat space, the direction vector of the vortex flow is two-dimensional. Thereby, the vortex formed in the storage chamber 10 can be stabilized.
Therefore, in the mixing apparatus 1A of the first embodiment, the oxygen concentration of the treated water is increased, and therefore, the ability to decompose organic matter by activated sludge can be enhanced.

  In addition, in the mixing apparatus 1A of the first embodiment, since the injection pipe 15c connected to the injection port 15a and the discharge pipe 16c connected to the discharge port 16a are not arranged linearly on both sides of the processing tank 2, the mixing is performed. While the installation space of apparatus 1A can be made small, the freedom degree of the layout of mixing apparatus 1A can be raised.

Further, the inlet and the outlet of the conventional mixing device have the same shape as the inlet 15a and the outlet 16a of the mixing device 1A of the first embodiment. In the conventional mixing apparatus, the inlet is open to the upper inner surface of the storage chamber, and the outlet is open to the lower inner surface.
In the conventional mixing apparatus, water to be treated and oxygen are injected into the storage chamber at the same flow rate and oxygen supply rate as the mixing apparatus 1A of the first embodiment.

  Then, in the mixing apparatus 1A of the first embodiment, as shown in FIG. 2, when the water to be treated and oxygen are injected into the storage chamber 10, the oxygen dissolution efficiency indicating the ratio of oxygen dissolved in the water to be treated is I asked. Similarly, in the conventional mixing apparatus, the oxygen dissolution efficiency when water to be treated and oxygen were injected into the storage chamber was determined. In the first embodiment, the amount of oxygen dissolved in the water to be treated is determined from the difference between the dissolved oxygen concentrations of the water to be treated and the treated water, and the amount of oxygen dissolved in the water to be treated is supplied to the water to be treated The oxygen dissolution efficiency of the treated water was measured, using the value obtained by dividing by as the oxygen dissolution efficiency.

As a result, the oxygen dissolution efficiency of the conventional mixing apparatus was 15.0%, and the oxygen dissolution efficiency of the mixing apparatus 1A of the first embodiment was 25.5%.
As described above, it was found that the water to be treated and oxygen were well mixed in the mixing device 1A of the first embodiment as compared with the conventional mixing device.

In the mixing apparatus 1A of the first embodiment as described above, the problem that the water to be treated and oxygen are easily discharged from the discharge port 16a without being caught in the vortex flow can be reduced. It will flow along a long path while being involved in a vortical flow in the storage chamber 10, and the behavior of the water and oxygen in the storage chamber 10 will be greatly disturbed.
And, in the mixing apparatus 1A of the first embodiment, the water to be treated and oxygen can be mixed well, and the installation space can be made small, so that the water to be treated and oxygen can be efficiently mixed in a space-saving manner. Can.
