Problems solved by technology

[0002] Ships navigating in waters with high sediment content and carrying out ballast in this water area, because the water contains a large amount of sediment, these sediments are deposited in the ballast tanks, causing the following two problems: one is the load of the ship The volume of cargo is reduced; the second is that the sediment is deposited in the ballast tank, causing the corrosion of ship components to intensify
This problem has plagued ships sailing in this water area for a long time. Removing these sediments is extremely difficult and consumes a lot of manpower and material resources.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, this technology is described in further detail:

[0019] Such as figure 1 Shown, traditional ballast tank is L type, and the present invention divides it into top edge ballast tank B and bottom ballast tank C, see figure 2 , the division position of ballast tanks of different ship types shall be determined according to the overall performance calculation to meet the ship stability and minimum draft requirements for coastal navigation, and the ballast water containing sediment can only be injected into the top side ballast tank B, Bottom ballast tank C can only be filled with ballast water without sediment; open non-dense floor water holes 3 are provided at the lower corners of the open non-dense floor plate 4; the radius of the open non-dense floor flow hole 3 It is R150mm to facilitate sediment discharge and prevent sediment deposition; flushing main pipe 5 is arranged on the main deck in the ballast tank B on the top s...

Abstract

The invention relates to a device and a method for preventing the sediment deposition and treating the sediment in a ballast tank of a ship. The traditional L-shaped ballast tank is divided into a topside ballast tank and a bottom ballast tank, wherein the topside ballast tank structure is provided with sediment outlet holes, and the shape and the size of the drain holes are optimized. During ballasting in the water area with a large sediment charge, only the topside ballast tank is ballasted, and the bottom ballast tank is in the void state, so that the ship can achieve the draught and the stability for safe sailing; and when the ship drives away from water field containing the sediment, the bottom ballast tank is ballasted, and the sediment in the topside ballast tank is discharged by a pump or gravity. For the conversion of the traditional ship, the invention has the advantages of slight change to the ship structure and the ballast piping, short construction time, convenient operation flow and lower cost; and for a newly-made ship, the invention has the advantage that the effect of preventing the sediment can be achieved as long as increasing less design and manufacturing cost, thereby achieving huge practical meanings and extensive application prospects.

Description

technical field [0001] The invention relates to a device and method for preventing sediment deposition in a ballast tank of a ship and for treating the sediment. Background technique [0002] Ships navigating in waters with high sediment content and carrying out ballast in this water area, because the water contains a large amount of sediment, these sediments are deposited in the ballast tanks, causing the following two problems: one is the load of the ship The volume of cargo is reduced; the second is that the sediment is deposited in the ballast tank, which causes the corrosion of ship components to intensify. This problem has plagued ships navigating in this water area for a long time, and the construction of removing these silts is extremely difficult and consumes a lot of manpower and material resources. Therefore, the anti-sedimentation technology of ballast tanks has great practical significance and broad application prospects. Contents of the invention [0003] T...
