Abstract

PURPOSE:To make possible the control of turbidity, dispersion, coagulation, etc., so as to be of any desired condition by means of a simple construction, by giving ultrasonic vibration in the transport flow direction of liquid, gas or granules which flow through a sonic pipe. CONSTITUTION:Ultrasound wave is projected to the transport flow direction of liquid, gas or granules which flow through sonic pipe by vibrating a vibrator 10 using an ultrasound oscillator 11. Consequently, the loop or node 12 of cavitation or ultrasound vibration is created in the sonic pipe 2. At that time, it is possible to pressurize the first tank 1 so that its pressure is higher than hat of the second tank 3 or control temperature by providing a heating or cooling device around the sonic pipe 2. For the dispersion and emulsification of water and benzine or toluene, orange oil, cream, resin processing liquid, etc. are supplied from a supply port 1a. When waste water produced by coal washing is supplied for the purpose of coagulation in the liquid, fine coal powder is collected into the second tank.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a turbidifier that uses ultrasonic waves to cloud and diffuse liquid, gas, or granules.

(Prior art) Conventionally, in the chemical industry using ultrasonic waves, there have been techniques such as ultrasonic emulsification, in which two liquids that do not mix with each other are irradiated with ultrasonic waves, and both liquid phases are dispersed in the other liquid phase. , the intensity of the ultrasonic waves irradiated to the particles in the liquid is greatly disturbed, and the force of collision breaks through the stable film of the droplet particles and causes them to coagulate into large particles. The soft gel-like or feather-like precipitate precipitated by chemical reaction can be easily dispersed by irradiating ultrasonic waves, and can be made into a colloidal liquid by coexisting with an appropriate stabilizer. Alcohol and flavorings are aged using ultrasonic waves.

[Problem that the invention seeks to solve]

However, as an ultrasonic dispersion device, for example, a radius of curvature of 3
A large number of titanic acid and barium oscillators are placed at the bottom of a 0cm spherical tank, and the liquid is circulated to the focal point. The dispersion emulsification mechanism applies ultrasonic vibrations by inserting a radiant disk attached to the tip of a horn connected to an ultrasonic vibrator into the liquid. As a device for agglomerating particles in a liquid, a device equipped with an ultrasonic vibrator on the side of a flow path is commonly used. However, these devices are designed to respond to various purposes such as ultrasonic dispersion, dispersion emulsification, and particle aggregation, and each has a complicated structure.

The present invention provides a turbidifier capable of turbidizing and diffusing liquid, gas, or particles with a simple configuration.

[Means for solving problems]

Therefore, in the turbidity device of the present invention, a sonic pipe is connected to a first tank that supplies one or more mixed fluids of liquid, gas, or granules, and the other end of the sonic pipe is connected to a second tank. and an ultrasonic vibrator is provided on the side of the first tank, the axis of the ultrasonic vibrator having substantially the same axis as the axis of the sonic pipe,
By installing the first tank near the inlet of the sonic pipe or by making the first tank have the same shape as a horn connected to an ultrasonic vibrator, the sonic pipe can be made to vibrate ultrasonically using an ultrasonic oscillator. Ultrasonic waves are irradiated in the flow direction of the sonic pipe, and the mixed fluid of one or more of liquid, gas, or granules supplied to the first tank is turbid, aggregated, diffused, etc. in the sonic pipe. The waste is collected in two tanks.

Therefore, it is possible to control the intensity of the applied ultrasonic vibration or to control the intermittent application in which vibration is applied for a predetermined time with a predetermined pause time, and to control the flow rate of the mixed fluid flowing through the sonic pipe at a high or low speed, or to change the flow rate at predetermined time intervals. A control device for the ultrasonic oscillator, a control device for the mixed fluid supply device, and a device for controlling both of the above-mentioned control devices are provided. .

[Effect]

Since the liquid, gas, or particles supplied to the first tank flows into the sonic pipe from the front of the vibrator, the ultrasonic vibration of the vibrator can be irradiated in the flow direction of the sonic pipe, and the sonic pipe By controlling the ultrasonic oscillator, it was possible to easily create nodes or antinodes of ultrasonic vibrations that were effective for purposes such as turbidity and aggregation. By increasing or decreasing the number of a pair of vibrators and sonic pipes, it is possible to provide a turbidity device with a predetermined capacity. Either or both are performed: intermittent application of vibration for a predetermined period of time after a predetermined rest period, or increasing or decreasing the flow velocity of the mixed fluid flowing through the sonic vibrator, or stopping the flow velocity for a predetermined period of time at predetermined intervals. This is how it was done.

3.29 and valve 26 are both controlled by control device 24.

One end of the sonic pipe 2 is connected to the first sonic pipe 2, and the other end of the sonic pipe 2 is connected to the second tank 3. Then, an ultrasonic vibrator 7 consisting of an electrostrictive body 5 of barium titanate and an elastic body 6 is screwed into a flange 4 provided on the side wall of the first tank 1, and then fixed with a nut 8. A vibrator 10 provided at the tip of a horn 9 connected to this ultrasonic vibrator 7
The axial center of the sonic vibrator 2 is made to have substantially the same axial center as the axial center of the sonic vibrator 2, so that liquid, gas, or particles flow into the sonic vibe 2 from around the vibrator 10 at an even flow rate.

A control device 32 is provided which connects the ultrasonic oscillator 11 to the electrostrictive body 5 and controls both the control device 31 of the ultrasonic oscillator 11 and the control device 24 of the mixed granule supply device. Furthermore, it goes without saying that a magnetostrictive vibrator can be used as the ultrasonic vibrator 1 in addition to an electrostrictive vibrator. Then, by vibrating the vibrator 10 with the ultrasonic oscillator 11, ultrasonic waves are irradiated in the flow direction of the liquid, gas, or particles flowing inside the sonic vibe 2.
Antinodes or nodes 12 in cavitation and ultrasonic vibration are created in the vibration. At this time, the first tank 1 may be pressurized to a higher pressure than the second tank 3, or the first tank may be placed above so that the sonic vibe 2 is vertical.

The device illustrated in FIG. 1 supplies liquid, gas, or granules through one or more supply ports 14a opened on the front surface of the ultrasonic transducer 7 fixed to the horn portion 14 with a fixing ring 15. Then, ultrasonic waves are applied by the ultrasonic vibration 7 in the flow direction of the sonic vibrator 13 and sent to the second tank 3.

The second tank 3 is provided with a lid 16, and turbid liquid, etc. is collected from the collection port 16a.In this case, the inside of the second tank 3 is also pressurized with a pressurizing device (not shown) to increase the pressure. This allows for control. Although not shown, the first tank 1 or the second tank 3 may be used for ultrasonic plating or ultrasonic electroforming, and the hydrogen gas generated at the same time as the metal is deposited at the cathode is subjected to the action of ultrasonic waves. It is also possible to remove it by using a method to prevent roughness and pinholes on the plated surface, and also to prevent hydrogen embrittlement.

As yet another modification of the present invention, the present invention provides a sonic vibrator in which a first tank on the supply side and a second tank on the receiving side are connected as described above, and a slurry-like substance is A mixture of one or more types of liquids, gases, and particles containing a fluid is vibrated by applying ultrasonic waves so that the fluid becomes a predetermined turbid state while the fluid flows and moves, the sonic vibrator is a resonator with a predetermined relationship to the ultrasonic frequency given by its material, dimensions, shape, and the properties of the flowing fluid, and the sonic pipe of this resonator usually has a Since a plurality of vibration antinodes and nodes are formed, for example, the ultrasonic vibration is applied for a predetermined time T and then a predetermined rest time depending on the properties of the fluid and the desired turbidity state. The application and the pause are repeated so as to pause, and during this vibration application time T, the flow of fluid in the sonic pipe is stopped to stop the supply of fluid from the first tank to the second tank, and During the rest time between the adjacent vibration application times T and T, the entire fluid in the sonic vibrator or the fluid between adjacent nodes is made to flow for a length of 1 or a predetermined plurality of units to create a turbid fluid. Only fluid in a predetermined turbid state can be supplied by flowing from the first tank into the second tank.

Another way to control the turbid state is to keep either the ultrasonic vibration applied during the sonic vibrator or the fluid flow constant, while the other is controlled to be strong, weak, or on/off.
It is preferable to provide a control means for switching off or continuously or switching between high and low speeds.

In addition, if multiple sonic vibrators with different sizes and shapes are available and the vibrators are configured to be used interchangeably, the frequency of the ultrasonic vibration can be set to be variable or interchangeable. It is necessary to configure an ultrasonic oscillator or a vibrator.
