Abstract

The present invention relates to an apparatus for killing botanical and animal microorganisms in ballast water of a ship. More specifically, the apparatus combines a conventional ultrasonic wave method with non-crystalline materials for differentiation and specialization to have high processing efficiency with a simple configuration, thereby more effectively killing the animal microorganisms in particular. The apparatus can be applied to the main process, post-treatment, and preprocessing of a conventional ballast water treatment system.

The apparatus can also enable vibration energy being transmitted in a liquid to be transmitted on a more three-dimensional basis and with a higher density. The apparatus can ensure significantly better performance in grinding, separating, and washing in other application fields compared to a conventional ultrasonic wave method. The apparatus can also effectively kill harmful microorganisms, fly larvae, and eggs in various waste water and water supply.

Description

  Technical Field [0001] The present invention relates to a high-efficiency ultrasonic microorganism extinction device using an amorphous material for ballast water treatment,

  The present invention relates to a device for killing copper and vegetable microorganisms in ballast water, and more particularly, to a method for destroying an animal microorganism by using an ultrasonic wave (non-crystalline) It can be applied to the existing ballast water treatment system by differentiating and characterizing it with high processing efficiency even in a simple configuration. Other application fields are expected to be superior to conventional ultrasonic methods for crushing, separating and washing, and it can be used as a technology to effectively kill harmful microorganisms in various wastewater, water, fry, larvae and eggs .

  Ballast Water Treatment System Ballast water treatment system is a device for killing animal / plant microorganisms existing in ballast water. Depending on the treatment method, it can be widely used for electrolysis, UV, ozone, plasma, Have been developed in a combination with the methods.

  Currently, the most representative example of the ballast water treatment system is electrolysis. The electrolysis method can be divided into direct death and indirect death according to microorganism death method. In the case of direct death, it is the death by the potential difference. Indirect death is the microorganism death by the total residual oxidant (TRO) in the water. In other words, the first direct death due to the potential difference is an environment in which a large amount of animal microorganisms can not survive due to the untreated water due to massive ballast water and the shortage of residence time in the reaction tank. Secondary indirect death is caused by the total residual oxide, Limitations of limited killing power and persistence are mentioned due to the resistance of

  The second is to kill the microorganisms by injecting total residual chlorine (TRC) generated by electrolysis in some seawater conditions or high concentration salinity in the ballast water pipeline by the chlorinator method. This method is also limited to killing and persistence due to resistance to various animal microorganisms.

  The third is UV (Ultraviolet) method. The UV method is a method of directly destroying microorganisms with strong ultraviolet energy. Theoretically, it has very high killing power, but it is practically limited to various microorganism deaths due to various floating substances in water and light interference and scattering due to turbidity. . In addition, since there is no residual oxide, it is difficult to expect secondary indirect death.

  The fourth ozone injection method. It is a very powerful oxidizing agent but it is difficult to dissolve in water due to lack of sufficient contact time due to massive ballast water. Especially, since ozone is usually very persistent, it is very difficult to kill animal microorganisms.

  In the fifth plasma method, a plasma discharge device in a pipe is installed to generate plasma. It has the greatest disadvantage that energy density and volume are biased due to intrinsic characteristics of the plasma in the pipe. Therefore, blind spots are widely generated in the piping and a large amount of untreated water due to a relatively large amount of ballast water is generated. In addition, it is hard to expect secondary indirect death due to the fact that almost no residual oxides are generated, and it is composed in combination with various systems for treating various ballast water.

  In-line injection system using filters and various oxidizing agents is applied in combination with other major ballast water treatment systems. The filter is limited due to aggressive cleaning, head loss, limited installation area, cost, etc. Also, various oxidant compounds have many difficulties due to cost, transportation and handling difficulties due to a large amount of water.

  However, in order to treat vegetable and animal microorganisms in the ballast water in the above-mentioned manner, more energy than necessary is consumed or the efficiency is low. Especially, it is pointed out that a problem that is very limited to the death of animal microorganisms is pointed out.

  The present invention relates to an apparatus for destroying copper and vegetable microorganisms in ballast water, and more particularly, to an apparatus for bonding non-crystalline materials to existing ultrasonic waves to more effectively kill animal microorganisms. The technology using existing ultrasonic waves has a characteristic that the longitudinal wave, which is inherent characteristic, is incident on the metal crystal structure, and the motion medium due to the regularity (uniform density, density, impedance, etc.) Resulting in a flat and simplified result. This is the biggest disadvantage that the vibration energy can not be utilized effectively and various changes to the ultrasonic oscillation are limited. Therefore, the present invention is characterized in that the vibration energy transmitted in the liquid is transmitted more densely and three-dimensionally by passing the reforming change to the ultrasonic oscillation through the non-crystalline material.

  In order to solve the existing problems, the present invention is to fabricate an oscillating surface of an ultrasonic vibrating part as a non-crystalline material or an isomerization material, or to make a vibrating outer surface of a vibrator as a single layer or a multi-layer. In other words, the longitudinal wave characteristics of the vibrating ultrasound and the planar vibration due to the metal crystal structure are incident on the non-crystallized object, and the shock waves, the surface acoustic waves Surface acoustic waves are generated and the bulk density of the ultrasonic medium is rapidly compressed due to the modified bulk waves propagated directly in the amorphous internal structure and the waves are deformed. When the various modified ultrasonic media are delivered to the fluid, the compression and the rarefaction become more dense and propagate into the liquid in a three-dimensional manner without a blind spot of the wave. This is called the Doppler effect. When the action of the physical function medium is increased, the microorganism treatment efficiency is increased with various directions of the ultrasonic modification. This is very effective for fluids moving at high speed because the material is strongly shaking.

  Theoretically, the propagation velocity of ultrasonic waves is known to be about 1480 m / s in water and the ultrasound velocity is much higher than the fluid velocity in the piping. The reason for the low microbial killing power of the conventional ultrasonic method is that there is no effective medium type in the extinction period, rather than a lack of residence time due to the rapid fluid velocity. Therefore, the present invention maximizes the microbial death in the water by changing the ultrasonic medium, and its role can be diversified compared with the conventional ultrasonic wave. In addition, by optimizing the medium for microbial destruction, it is possible to remove the ultrasonic contact blurring in the fluid and effectively cope with it.

  The present invention relates to a device for killing microorganisms of copper and phytoplankton in ballast water, and more particularly relates to a method for destroying animal microorganisms by combining an existing non-crystalline material with an ultrasonic wave method, It is not limited to various water quality environments (water temperature, turbidity, fresh water, seawater, etc.), low manufacturing cost, maintenance and parts replacement costs It can be mounted independently on the ballast water treatment system of various ships or on the front and rear end of the ship, and other application fields can be divided into crushing, It can be expected to have outstanding performance even in cleaning, etc., This advantage is possible with the technology to effectively kill the creature, fry and larvae, eggs and more.

The ultrasonic wave method of the present invention is formed into a unit of a plug flow reactor (PFR) type, and is configured as a flange pipe type so that it can be easily coupled to a pipe. The vibrating outer wall case is made of a metal crystal structure and the part in contact with the fluid is made of an amorphous material (non-crystalline material). This is for the ultrasonic vibration to oscillate effectively by modifying the fluid.

2 is a structural view of an ultrasonic device using an amorphous material used in the present invention.
FIG. 3 to FIG. 6 are diagrams of a partition or multi-layer, bundle piping structure for increasing the efficiency according to the present invention;

  The present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the ultrasonic transducer has an integrated structure of an ultrasonic wave part and an outer housing, and a control device for driving ultrasonic waves is installed at an upper end part thereof. In the outer housing, a wiring device is enclosed in the form of wrapping a vibration oscillator. A control unit for driving and controlling the vibrator is disposed above the housing by integrating the wiring. As shown in FIG. 2, the vibrator (No. 2) surrounds the pipe in the outer housing (No. 1) and is arranged asymmetrically or circularly and linearly.

  The oscillator can be variously configured in frequency variation, circular shape, linear shape, asymmetric structure and multi-frequency for changing the ultrasonic wave modification, and adjusts the number and position of the vibration oscillator according to the object. Mine pipe housing (3) to fix the vibrator is composed of circular piping or square shape. The vibrator is fixed by a socket type, screw fixing type, one touch type, welding, etc., A vibration surface (No. 4) is formed in the form of a pipe of a pipe. Spacer (6) is installed to maintain the gap with the reversible amorphous pipe (5) to prevent vibration of the vibration zone. The space between Spacer (No. 6), ie, the vibration zone and the reversible amorphous pipe, is filled with circulation water or a part of the process water. This is to prevent the destructive interference of medium particles due to the interface between the two materials as the vibration energy is directly transmitted from the metal material to the amorphous material. Also, it is possible to use the case where the enemy is passed directly to the space of Spacer (No. 6) instead of the circulation number in the structure of the open structure in the space where the Spacer (6) is installed. This is because the vibration energy is incident on the amorphous material and is reversed backward by a shock wave (Shock wave), surface acoustic wave, superposition, diffraction, refraction, Reversible waves are processed by reforming propagation. In place of the space between the vibrating part and the reversible amorphous pipe (No. 5), that is, the space for preventing the vibration energy counter interference, the amorphous material or the heterogeneous material is directly attached to the inside of the pipe vibration surface Coating or lining can also be used.

(5) can be used in the form of a circle, a square, etc. Also, the inside of the reversible pipe (No. 5) can be used to prevent reflection, refraction, diffraction, superposition and disturbance prevention, and amplitude In order to increase the efficiency through reinforcement change, shock waves, surface acoustic waves, and reforming amplification of a bulk wave, (FIGS. 5 and 6).
