Embodiment Construction

[0064] Next, the structure of the ship ballast water treatment device according to the present invention will be described with reference to the accompanying drawings. Components with the same reference numerals in different drawings are identical or similar to each other. The present invention is not limited to these contents, but is described in the claims, and includes all changes within the spirit and scope of the claims and their equivalents.

[0065] figure 1 is a schematic longitudinal sectional view showing a ballast water treatment device for ships according to an embodiment of the present invention. figure 2 is along figure 1 Sectional view of line A-A. The cylindrical filter 1 is arranged around an axis C as a rotation center. The filter 1 is mounted such that it is freely rotatable around a central tube 4 which does not rotate and is arranged in the centre. exist figure 1 In the above, the filter 1 is a pleated filter having pleats formed such that convex po...

Abstract

A ballast water treatment device is provided with: a filter which is cylindrically disposed so as to surround an axis; a case which has an outer cylindrical part provided so as to surround the filter; a rotation mechanism which rotates the filter about the axis; a water-to-be-treated nozzle which discharges water to be treated to a filter outside region formed by the outer peripheral surface of the filter and the outer cylindrical part; a washing water nozzle which discharges washing water toward the outer peripheral surface of the filter; a filtrate water flow path through which filtrate water transmitted through the filter is led from the inside region of the filter to the outside of the case; and a drainage flow path through which drainage water not transmitted through the filter is drained from the filter outside region to the outside of the case.

Description

technical field [0001] The present invention relates to a system for treating ballast water, which is stored in a ship, such as a tanker, to keep the ship stable during voyage. In particular, the present invention relates to ballast water treatment devices installed in ships and used to remove microorganisms from seawater. Background technique [0002] In recent years, the disposal of ballast water stored in ships has become a problem. Ballast water is sea water stored in a ship to keep the ship sailing safely even when it is empty. The ballast water is loaded into the ship from the sea area near the port when the ship leaves the port, and the ballast water is discharged into the sea when the ship enters the port and loads cargo. When ballast water is discharged to a sea area different from the sea area from which the ballast water was initially taken, the transfer of organisms in the seawater to sea areas other than their original habitat may have a significant impact on ...
