Embodiment 1

[0038] For a 114,000-ton oil tanker, the ballast pump processing capacity is 2000m3 / h×2, and the ballast water is treated by the new electrolytic seawater method ship ballast water treatment system. The type of electrolysis unit is selected with a corresponding treatment capacity of 2000m3 / h. The whole system can run stably for multiple voyages and for a long time, and the ballast water treatment meets the requirements of the Convention.

Embodiment 2

[0040] For a 13500TEU bulk carrier, the treatment capacity of the ballast pump is 1500m3 / h×2, and the ballast water is treated by the electrolysis method in advance. The type of electrolysis unit is selected with a corresponding processing capacity of 1500m3 / h. The whole system can run stably for multiple voyages and for a long time, and the ballast water treatment meets the requirements of the Convention.

[0041] Factory experiments and real ship experiments have proved that electrolysis of ballast water treatment in advance is feasible. During the operation of the system, parameters such as pressure and flow are stable without large fluctuations. Compared with the original technology, the type selection of the electrolysis unit can be reduced by 30%~50%, and the layout is more flexible. The electrolyte storage tank is used as a hydrogen removal device, and the average hydrogen removal efficiency reaches 99%. The whole system can fully meet the requirements of ship ballast wat...

Abstract

The invention discloses an electrolysis seawater method ship ballast water treatment system. The system comprises an electrolysis hydrogen removing unit; the electrolysis hydrogen removing unit includes an electrolyte storage tank, an electrolysis unit and an electrolyte circulating pump; an inlet and an outlet of the electrolyte storage tank are respectively connected with an outlet of a prefilter and an inlet of a medicine charging pump; two circulating joints of the electrolyte storage tank are serially connected with the electrolysis unit and the electrolyte circulating pump to form a circulating loop; and a hydrogen removing device is mounted at the top end of the electrolyte storage tank. The electrolysis seawater method ship ballast water treatment system has the following advantages: the electrolyte storage tank is provided, and the electrolysis unit is used for circularly electrolyzing seawater, so that the ballasting after electrolysis is realized, the equipment selection limit from ballasting during electrolyzing is overcome, the electrolysis unit with a small model number can be selected, and the multi-way medicine charging complex process of one set of electrolysis units can be realized; the electrolyte storage tank is fully used for realizing the liquid storage function, and meanwhile, an air blowing device is added for realizing the hydrogen removing function; and the electrolysis unit is simplified, and a hydrogen removing part is canceled, so that the equipment is more compact, the operation is more stable, and the cost can be reduced.

Description

technical field [0001] The invention relates to a ship ballast water treatment system by electrolytic seawater method, which is mainly used for. The invention belongs to the field of ship ballast water treatment system by electrolytic seawater method. Background technique [0002] The electrolytic seawater method ship ballast water treatment system is generally arranged in the engine room and upper deck of the ship according to the space of the ship. It uses sodium hypochlorite produced by electrolytic seawater to kill microorganisms in the ballast water to meet the requirements of off-site discharge. When the ship is ballasting, the ballast water treatment system starts, and the electrolyzed seawater is injected into the main pipeline. At the same time, the residual chlorine detection equipment detects the chlorine concentration in the ballast water and feeds back to the control system. The system adjusts the dosing according to the detected value When discharging, if the ...
