Abstract

PROBLEM TO BE SOLVED: To enable effectively forming a liquid mixture by providing a gas- liquid mixing device equipped with an ultrasonic wave generator with an ultrasonic vibrator transducer for making liquid to be treated fine particles, an agitating plate for making contact between gas and the fine particles, a coagulator for collecting the fine particles, and a fine particle removing tank for recovering the fine particles. SOLUTION: A gas-liquid mixing tank 4 is constituted of an ultrasonic vibrator transducer 8, an ultrasonic wave generator 13, an agitating plate 9, a coagulator 7, an exhauster, control valves 1, 2, a pressure control valve 3, and a liquid adjusting float 12. And on operation, introduced liquid is made into fine particles by the ultrasonic vibrator transducer 8 and is dissipated in the tank while keeping it at such level that the production of the fine particles by the ultrasonic vibrator transducer 8 is made optimum by the control valve 1 and the liquid adjusting float 12. On the other hand, gas sent from the pressure control valve 3 passes below the agitating plate 9 to raise the dissipated fine particles into the tank. In this way, the gas undergoes dissolving transfer to the fine particles, and the fine particles hit on each other or coagulate by the coagulator 7 and grow and fall to turn them into a liquid mixture.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a gas-liquid mixture in which a gas is dissolved in a low-viscosity liquid, in which fine particles of the liquid are formed by an ultrasonic vibrator so that the particles are effectively brought into contact with the gas to efficiently generate the gas. The present invention relates to a gas-liquid mixing device that mixes and dissolves and moves with a liquid.

2. Description of the Related Art Conventionally, this kind of mixing method is a method in which a gas is made fine by various methods, brought into contact with a liquid, mixed and dissolved.

[0003]

In conventional gas-liquid mixing, gas bubbles are released into a liquid in a gaseous state to mix them. In order to improve the gas melting efficiency, gas bubbles are subdivided. It is necessary to increase the surface area, and there is a tendency that a mechanical device such as a gas pressure device is increased in size. The present invention uses the electronic device and the ultrasonic vibrator to finely divide the liquid to be mixed to increase the surface area, and to efficiently make the mixed liquid by efficiently contacting the mixed gas. This was done to solve the problem.

[0004]

As shown in FIG. 2, the gas-liquid mixing apparatus comprises an ultrasonic vibrator for converting the liquid to be treated into fine particles in a gas-liquid mixing tank provided with an ultrasonic generator. A stir plate for efficiently bringing the gas to be brought into contact with the fine particles, a coagulation device for collecting the fine particles, and a departicle tank for collecting the fine particles are provided.

[0005]

In the present gas-liquid mixing tank, the liquid is converted into fine liquid particles by an ultrasonic vibrator. The fine particles come into contact with the gas by dispersing and stirring the gas sent with a slight pressurization, and the gas is dissolved in the fine particles. The fine particles also collide with each other or grow due to agglomeration by an aggregating device, and gradually fall to become a mixed solution.

[0006] In the present de-particulation tank, a gas containing fine particles discharged without being coagulated from the gas-liquid mixing tank is taken in, discharged from the gas disperser into the liquid, and the fine particles are dissolved in the liquid, and the gas is dissolved. Discharge.

In this gas-liquid mixing apparatus, a liquid and a gas having a slight pressure are introduced into a gas-liquid mixing tank through a control valve and a control valve, and are effectively mixed by using ultrasonic waves. The particles are collected and the mixture is continuously removed.

【Example】

Hereinafter, an embodiment of the present gas-liquid mixing tank will be described. As shown in FIG. 1, the gas-liquid mixing tank is provided with an ultrasonic vibrator for producing fine particles of the liquid to be treated and an ultrasonic generator having a function of generating ultrasonic waves capable of always producing optimal liquid fine particles by the vibrator. Device, a stir plate contributing to the mixing of the fine liquid particles and the gas and an aggregating device for aggregating the mixed fine particles,
An exhaust device, a control valve for controlling liquid and gas, a pressure control valve, and a liquid adjusting housing are provided. In the operation of the gas-liquid mixing tank, the introduced liquid is converted into fine liquid particles by the ultrasonic vibrator and dissipated into the tank while maintaining the level at which the production of fine particles by the ultrasonic vibrator is optimized by the control valve 1 and the liquid adjusting housing. Is done. On the other hand, the gas sent from the pressure control valve 1 with a slight pressurization mainly passes through the lower part of the stirring plate to spread and mix the dispersed liquid fine particles into the mixing tank. This dissolves and moves the gas into the liquid fine particles. Further, the fine particles collide with each other or aggregate with an aggregating device, and grow and fall to form a mixed solution.

An embodiment of the present fine particle removing tank will be described below. As shown in FIG. 2, the apparatus is provided with a control valve 2 (liquid supply), a liquid adjustment housing, a gas disperser, an exhaust port, and a liquid outlet. The operation of the fine particle removing tank is as follows. The gas containing fine particles sent from the gas-liquid mixing tank by the air supply pipe is released from the gas disperser into the liquid replenished by the control valve 2, and the fine particles are melted into the liquid to dissolve the gas. And separate. The exhaust gas is exhausted from an exhaust port. The mixed liquid is taken out from the liquid outlet.

Hereinafter, an embodiment of the present gas-liquid mixing device will be described. As shown in FIG. 2, the present gas-liquid mixing apparatus includes a gas-liquid mixing tank according to the embodiment 0008, a fine particle tank according to the embodiment 0009, a liquid introduction control valve 1, a liquid supply control valve 2, a gas introduction control valve 1, a mixed liquid. It is configured to have an outlet and a density sensor. The operation of the gas-liquid mixing device is as follows.
It is stored in the mixing tank through the coagulation device. Also, the level is controlled and controlled by the liquid control valve 1 so that the ultrasonic vibrator can produce fine particles most efficiently. still,
The gas is made into a slightly pressurized state by the suppression valve 1 and released to the stirring. In the de-particle tank, the mixed liquid level is properly maintained by the liquid adjustment control and liquid supply control valve 2. In addition, by controlling the ultrasonic generator and the ultrasonic vibrator by the concentration sensor in each tank, the mixing and concentration of the gas and liquid are controlled, and the desired concentration solution is continuously obtained. Also, as shown in Figs.
By converting the coagulation device and replacing it with a uki level meter, the device can be expected to be smaller. If the residual concentration of the discharged gas is high, the exhaust gas can be returned to the pressure control valve 1 and circulated.
