Problems solved by technology

However, the above methods have their own advantages and disadvantages, and their use environments and methods are different, which will cause more or less inconvenience in the process of ballast water treatment
In addition, the existence of ballast water will increase the weight of the ship itself, increase the fuel consumption of the ship, increase the inertia of the ship, and reduce the flexibility of the ship

Embodiment Construction

[0017] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 to Figure 3 As shown, a through-type ballast water tank described in the present invention includes a ballast water tank 1 mounted on the hull. The ballast water tank 1 is provided with several independent compartments 5, and one end of the independent compartment 5 is provided with a water inlet 2. The other end is provided with a water outlet 3, and the water inlet 2 and the water outlet 3 are connected through. An opening is provided on the outer plate below the waterline of the bow of the hull and is connected to the forepeak tank. The peak tanks are connected, and several air ballast systems 4 are arranged on the top of the independent cabin 5, and a movable pressure plate 7 is arranged inside the independent cabin 5, and the movable pressure plate 7 is controlled to move by a mechanical lifting device.

Abstract

The invention relates to the technical field of ballast water long-distance discharge, in particular to a through type water ballast tank which comprises a water ballast tank body. The water ballast tank body is provided with a plurality of independent cabins. One end of each independent cabin is provided with a water inlet, and the other end of each independent cabin is provided with a water outlet. The top of each independent cabin is provided with a plurality of air ballast systems. A movable pressing plate is arranged in each independent cabin and is controlled by a mechanical lifting device to move. By means of the structural arrangement, a ship is through all the time through the water inlets and the water outlets in the sailing process, and the air ballast systems correspond to the movable pressing plates, so ballast water is discharged within the minimum safety range, seawater microorganisms or algae are prevented from being brought into an outer domain, the influences of external microorganisms are fundamentally eliminated, the problem of external microorganism invasion caused by ballast water long-distance discharge is greatly solved, the weight of the ballast water in the weight of the ship is reduced, ship loads are reduced, and the ship sailing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ballast water discharge in different places, in particular to a through-type ballast water tank. Background technique [0002] With the advantages of large carrying capacity and low operating costs, modern ships have always occupied a pivotal position in the global economic field. Today's maritime transport ships in the world are developing in the direction of large-scale, specialization and automation, which inevitably brings a series of problems. Among them, the alien biological invasion caused by the off-site discharge of ballast water from international sailing ships has become more and more popular. attention. If the situation of alien biological invasion is to be alleviated, some measures must be taken artificially. [0003] The methods currently being studied to treat ballast water mainly include: physical treatment methods, such as filtration, improvement of ship design, heating, ultrasonic wave...
