Description

Automatic neutralization device for ship

Technical Field

The utility model relates to a boats and ships ballast water technical field specifically is an automatic neutralization apparatus is used to boats and ships.

Background

With the continuous acceleration of the global economy integration process and the rapid growth of the international logistics industry, ship transportation is an important part of the global logistics chain. Statistically, more than 80% of the goods in international trade are transported by ships. During the ship sailing process, the ballast is an inevitable state, and when the ship is added with ballast water, local aquatic organisms are loaded into the ballast tank along with the ballast water until the ship is discharged to a destination sea area along with the ballast water after the voyage is finished. Ballast water follows the vessel from ground to ground, causing the transmission of harmful aquatic organisms and pathogens. In order to effectively control and prevent the propagation of harmful aquatic organisms and pathogens from ship ballast water, International Maritime Organization (IMO) passed international treaty on ship ballast water and sediment control and management in 2004. The convention stipulates that since 2009 all newly built ships must be equipped with ballast water treatment facilities and retroactively implemented on existing ships. A great deal of research is being carried out on the technology of ship ballast water treatment at home and abroad. The neutralizing agent adopted by the technology developed abroad is mainly sodium thiosulfate or sodium sulfite, and the neutralizing agent is added according to the proportion of a stoichiometric formula, so that residual TRO cannot be completely neutralized and cannot reach the discharge standard specified by IMO, and therefore, the neutralizing agent needs to be excessive. However, in the conventional neutralization method, the excessive addition amount of the neutralizing agent is too large, which causes problems that the excessive neutralizing agent consumes dissolved oxygen in water, causes oxygen deficiency in water area, also causes damage to marine environment, and affects growth of marine organisms such as algae, invertebrates, fishes, and the like.
