Description

AOP (Advanced Oxidation Process Three-way catalytic sterilizing lamp)

The present invention relates to an AOP three-way catalyst disinfection and the like. More particularly, the present invention relates to an efficient disinfection and sterilization of organic matter such as various microorganisms and contaminants, including various marine organisms present in the ballast water flowing into or out of a ballast tank of a large- AOP three-way catalyst sterilization that can be done.

Cargo ships or passenger large ships have a limited total weight that can be loaded for safe and efficient operation. Therefore, filling or discharging sea water in ballast tanks in which the cargo is loaded or unloaded separately on the lower and both sides The left and right equilibrium of the ship is controlled. In this way, the seawater filled in the ballast tank in order to hold the center of gravity of the ship is called the equilibrium of the ship.

In general, cargo transportation and large-scale passenger vessels maintain the equilibrium of the ship by filling the ballast tank with ballast water separately in the lower and both sides of the ship for safe transportation of the ship, The ballast water which plays an essential role for the ship is repeatedly flowed in or out depending on the weight of the object to be loaded on the ship. This causes the ballast water to flow into the ballast tank at the port where the object to be transported is loaded, The ballast tanks will discharge the ballast water at a nearby port outside the port where the intended destination is being transported.

As described above, the ballast water is discharged from the ballast water of various kinds contained in the ballast water in the course of repeating the inflow and outflow every time the object to be transported is loaded or unloaded. As a result, Extinction, and transitions of biological populations, which can cause very serious problems to disturb marine ecosystems.

As an example, if we look at an example of ecological disturbance due to the actual movement of ship ballast water, European species of speckled mussels reproduced in the United States causing confusion in indigenous ecosystems and harmful aquatic organic matter Has caused massive damage to the Australian pearling industry and has caused damage to marine ecosystems due to the emergence of submerged microorganisms that did not live in the harbors and coastal waters of Brazil. In addition, in Korea, A case in which the crustacean monstrolla was found in the port of Youngduk, Gyeongbuk, has been reported.

The International Maritime Organization (IMO) has decided to restrict the exchange of ship equilibrium within the port, or to exchange it before the port of call, The International Convention for the Control of Ship Ballast Water and Sediment has been adopted to establish the water quality standards for ship ballast water discharged from the ship, Have mandated that shipboard ballast water treatment facilities be mandatory for some 68,000 ships operating around the world.

The United States, which is about 65% of the world's outer marine vessels, calls for ballast water treatment technology that is 1000 times stronger than the international standards already agreed to protect its marine environment. I have said that I have a plan.

On the other hand, the ship ballast water treatment technology is largely divided into in-line treatment methods at the time of inflow and outflow of the ballast water and in-tank treatment methods during the sailing after the ballast water is introduced. Currently, the international ship ballast water treatment technology adopts the pipeline treatment method considering the miniaturization of the treatment device and the operation efficiency.

The vessel ballast water treatment apparatus according to the prior art includes a vessel ballast water treatment apparatus using seawater electrolysis, which is disclosed in Korean Patent No. 10-1070948. However, this apparatus includes an oxidant concentration measuring apparatus, a seawater temperature control apparatus, a heat exchanger It is very difficult to install it in addition to existing vessels because of its large number of components and complicated structure and relatively large area of installation space. Therefore, it is difficult to maintain and maintain the reliability, Is pointed out as a problem.

In addition, Korean Patent No. 10-1495726 has proposed a self-cleaning type ship ballast water treatment apparatus for ultraviolet sterilizing lamps. However, since water molecules are formed and exposed to ultraviolet rays emitted from an ultraviolet sterilizing lamp to protect and protect bacteria Another drawback of the ultraviolet ray is that it is a shallow film formed by a mineral or an organic material, which causes a loss of light emitting ability.

Registration No. 10-1070948 (issued October 10, 2011) Registration No. 10-1495726 (Bulletin of Feb. 25, 2015)

At this time, the (+) and (-) tungsten heating electrodes 7a 7b emit red light. However, when the amorphous particles 8 are amplified by the amalgam particles 8 attached at regular intervals on the inner surface of the inner quartz tube 2, the high-voltage light wavelength is in a blue state, The light that is amplified by the amalgam particles (8) (+) And (-) tungsten heating electrodes 7a and 7b, the red high voltage light is far brighter than the red light.

A three-way catalyst coating 9 is formed on the outer surface of the inner quartz tube 2 to generate an intermediate product called an OH radical by the light amplified by the amplifying action of the amalgam particles 8.
