Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ballast water filter device,

The present invention relates to a vertical split type marine ballast water filter apparatus.

More specifically, foreign matter and microorganisms contained in the ballast water are distributed and separated from each other in the sub-balloons and the sub-balloons, so that foreign matter and microorganisms in the balloons are concentrated in the lower portion of the filter unit. The present invention relates to an upper and lower separation type marine ballast water filtration device capable of preventing the above-

In general, when the cargo is loaded on the ship, it may not be balanced before or after the ship. To this end, a ballast tank is provided in the inside of the vessel, and ballast water is introduced into or discharged from the ballast tank to solve the imbalance of the vessel due to the vessel loading.

On the other hand, as the international capacity is gradually increased and the marine transportation ratio is gradually increased, the ship is rapidly becoming larger and the amount of ballast water used in the ship is greatly increased.

As the amount of marine ballast water used in vessels increases, the number of cases of damage caused by marine ecosystems due to foreign marine species is also increasing. In order to solve these international environmental problems, In 2004, the International Convention for the Control and Management of Water and Sediments was adopted. The Convention will enter into force one year after the date on which more than 30 countries are joining and the ship's holdings in the participating countries are more than 35% of the world's ship holdings. As of September 7, 2016, Exceeding 35% of ship holdings. Therefore, the agreement is expected to come into force on September 8, 2017, 12 months later.

As the Convention enters into force, it is obligatory to install a ship ballast water treatment system (BWTS) on the ship, which will prevent damage to ecosystem disturbance and harmful pathogens caused by ballast water ballast water.

On the other hand, a ship ballast water treatment apparatus installed on a ship is mainly subjected to a filtration method using a filter, followed by physical or chemical treatment such as electrolysis or ultraviolet ray treatment. Fig. 1 shows a conventional ballast water treatment apparatus Fig.

In the conventional ballast water treatment apparatus, it is configured to be capable of driving to automatically clean foreign substances deposited on the filter during use.

That is, when the ship ballast water treatment apparatus shown in the drawing is in the normal filtration operation, the ballast water flows into the inflow water line 1, flows through the filter installed in the housing 2, If the filter is clogged due to a large amount of foreign matter deposited on the filter, the cleaning operation is started by sensing the clogging of the filter. That is, during the washing operation, the ballast water is moved from the treated water line 4 to the washing line 5, thereby removing foreign matters stuck in the filter, thereby enabling continuous ballast water treatment.

However, when the concentration of the solid matter among the foreign substances entering the filter is increased, the cleaning speed can not keep up with the filtration rate, and the sediment foreign matter gradually increases. As a result, There is a problem that the processing apparatus can become inoperable.
