Problems solved by technology

[0004] In addition, the arrangement of the ballast piping system on the ship and the water quality are also complex and changeable. In addition to the common arrangement of the ballast piping system below the steel plate in the cabin, for some specially designed ships such as oil tankers and chemical tankers, all The ballast piping system or part of the ballast piping system will be submerged below the water surface. Failure to solve the installation problem of the TRO analyzer will seriously limit the market competitiveness of the ballast water treatment system using active substances
As for the stripping and discharging piping system in the ballast piping system, because it is used for the discharge of ballast tank bilge water, after long-term operation, the bilge water discharged by the stripping piping system contains certain sediments and other sediments. , it is very easy to block the sampling pipeline of the TRO analyzer, or cause the failure of the internal measurement components of the TRO analyzer, so that the TRO analyzer cannot work normally, and then lead to the failure of the entire neutralization treatment device

[0024] Such as figure 1 As shown, the ballast water TRO (total residual oxidant, total residual oxide) neutralization treatment system provided by the first embodiment of the present invention includes a ballast tank 1, a ballast pump 2, a neutralizer storage tank 4, and a control system 5. Fresh water pipeline 6, neutralization solution tank 7, neutralizer distribution device 8, neutralizer dosing pump 10, control valve 12, discharge pipeline 16 and neutralization dosing pipeline 17, neutralizer storage Solid neutralizing agent is stored in the tank 4;

[0025] The outlet of the ballast tank 1 is connected to the outboard through the discharge pipeline 16, the ballast pump 2 is arranged on the discharge pipeline 16, and the outlet of the neutralizer storage tank 4 is connected to the neutralization solution tank through the neutralizer distribution device 8. The neutralizing agent inlet 71 of 7 communicates, the outlet of the fresh water pipeline 6 communicates with the fres...

example

[0053] 1. The ballast pumps and outboard points of the entire ballast piping system of a chemical tanker are all submerged below the water surface. During discharge, the treated ballast water in the ballast tank is directly discharged to the tank through the stripping pump. Overboard, it is not possible to install a suitable TRO analyzer or set up a TRO sampling point for TRO monitoring at the outboard point. After adopting the neutralization treatment system of the present invention, by obtaining the ballast pump flow rate, the residence time of the treated ballast water in the ballast tank and other information, a neutralizer solution with a suitable concentration is automatically prepared. After the discharge starts, The control system automatically adjusts the dosing flow rate of the neutralizer dosing pump according to the discharge flow rate to ensure that the TRO in the discharge water is fully and effectively neutralized, meeting the TRO discharge requirements of IMO an...

[0056] Such as figure 2 As shown, the ballast water TRO neutralization treatment system provided by the second embodiment of the present invention is substantially the same as that of the first embodiment, except that the method and device for obtaining the ballast water volume are different.

[0057] Specifically, in this embodiment, the ballast water TRO neutralization treatment system further includes a second liquid level gauge 31 and a liquid level telemetry system 32, the second liquid level gauge 31 is arranged on the ballast tank 1, and the liquid level telemetry The system 32 is in signal connection with the second liquid level gauge 31 , and the control system 5 is also in signal connection with the liquid level telemetry system 32 at the same time.

[0058]Due to the different space designs of different ships, the shape of the ballast tank 1 on some ships is irregular, so it is impossible to directly calculate the volume of ballast water in the ballast tank 1 throu...

The invention further provides a ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ballast water TRO neutralization treatment system and a ship equipped with the system. Background technique [0002] The International Maritime Organization (IMO) divides the treatment methods of ballast water management systems into two categories: methods using active substances and methods without using active substances. Active substance refers to a substance or organism, including viruses or fungi that have general or special effects on harmful aquatic organisms and pathogens, and can kill target organisms in seawater. The treatment method using active substances is mainly to inject one or more specific active substances into the ballast water after being produced by physical or chemical methods or directly prepared, and to use the inactivation and sterilization ability of the active substances to realize the treatment of ballast water. In order to meet the discharge standa...
