Description

[0001] CARTRIDGE AUTO-CHANGING CHEMICAL INJECTION SYSTEM [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic cartridge replacement type cartridge insertion system, and more particularly, to a cartridge replacement type cartridge insertion system which automatically replaces a cartridge with a new one.

Most ships, except for cargo vessels, are operated one way to exchange cargo between the two regions. Since the ship has operated one way under full load, ballast water (ballast water) is flown into the ship in order to improve balance, safety and maneuverability of the ship.

At this time, the ballast is filled in one port and transported to another port through a ballasting operation, and then discharged to another port through a deballasting operation.

The ballast water discharged from such a long distance contains numerous marine organisms and pathogens, and marine organisms and pathogens released with ballast water are harmful to the marine ecosystem of the area, It is threatening.

If marine life that does not exist in the area is introduced into a new ecosystem, it affects existing marine life that does not have a defense system for new species, and the ecosystem is disturbed.

Harmful bacterial pathogens such as cholera may also be present in the equilibrium water, and pathogens entering the ballast tank may propagate within the bactric tank and spread the disease to areas where ballast water is discharged.

Recently, the International Maritime Organization (IMO) in the United States, where 65% of the world's vessels are sailing, calls for ballast water treatment technology that is 1,000 times stronger than previously agreed standards.

In addition, according to the Convention on Ship Ballast Water Management adopted by the International Maritime Organization in 2004, a ballast water management system (BWMS: Ballast Water Management System) must be installed in all vessels with a gross tonnage of 400 tons or more by 2024.

As the regulations on ballast water treatment are strengthened, the importance of ballast water treatment apparatus for treating ballast water is increasing.

There are two main methods of treating ballast water. One is a physical treatment method using electrolysis, ultraviolet (UV) treatment, and ozone treatment, and the other is a chemical treatment method using chemicals.

The physical method is mainly used for large-sized ships because the scale of the facility is very large and the initial cost is very large. For small-sized small ships, a chemical method is used which is relatively simple and requires low equipment cost.

A chemical treatment method is a method of putting a drug (sterilizing agent) capable of killing marine life into a ballast tank, in which a hopper for inputting medicine is provided, and a worker inputs the powdered medicine stored in the bag into ballast water . Then, the drug is mixed with the equilibrium water using a separate stirring device.

The drug should be dosed in proportion to the volume of ballast water and should be injected so that the powdered drug can dissolve smoothly in the ballast water. Such work is done by special equipment or manpower.

Sodium dichloro-isocyanurate (NaDCC) is the most widely used drug for treating ballast water. However, since NaDCC is fatal to eyes and respiratory tract, considerable care is required in handling it.

NaDCC in aqueous solution is difficult to handle because it is bulky and deteriorates in quality depending on temperature, and NaDCC in powder form is handled in a bag, and it is scattered during use and affects the respiratory system, so it is difficult for the operator to handle it safely.

In order to handle NaDCC in powder form, specialist personnel should be put in to handle it, and a separate ventilation facility should be provided at the place where it is handled. Therefore, the system for handling NaDCC becomes complicated and occupies a large space in the vessel there is a problem.

While the vessel is navigating a long distance, it uses a large amount of NaDCC. NaDCC is transported and loaded in the bag, so the workforce must be constantly input in order to put it into ballast water. Handling NaDCC with manpower can lead to constant exposure of the handler to NaDCC.
