Embodiment Construction
[0019] A hydrogen removal method for a ship's ballast water management system in the present invention is characterized in that the sodium hypochlorite solution mixed with hydrogen gas produced by electrolysis enters the cylinder body from the inlet along the tangential direction of the circumference at a relatively high flow rate to generate rotational motion. Under the action of centrifugal force, the sodium hypochlorite aqueous solution is thrown towards the wall of the cylinder, forming a negative pressure in the cylinder center, so that the hydrogen gas is separated from the solution, gathers in the cylinder center and is discharged upward through the exhaust port; while the sodium hypochlorite solution is discharged through the lower part of the cylinder. The discharge port is sent to the ballast water main pipeline.
[0020] Before the hydrogen gas is discharged upwards, the processes of uniformly distributing the pressure on the cross section, filtering out the water va...

A dehydrogenation method and a device of a ship ballast water management system. A sodium hypochlorite solution with hydrogen generated by electrolysis is allowed to flow into a cylinder from an inlet with a high flow velocity along a circumferential tangent direction so as to perform rotary motion; under the action of centrifugal force, the sodium hypochlorite solution is thrown to the cylinder wall, and a negative pressure is formed at the cylinder center; therefore hydrogen is separated from the solution, aggregates at the cylinder center, and flows upwards and is discharged through an orifice plate, a corrugated plate, a foam-isolating net, a one-way inverted valve, a flow-limiting bolt, and a gas exhaust port; the sodium hypochlorite solution is delivered to a ballast water main pipeline from a liquid discharging port at the lower part of the cylinder. The beneficial effect of the invention is that: with the method and device of the invention, the size of a dehydrogenation deviceof an electrolytic-method ship ballast water management system is reduced by 60%. Testing experiment proves that the dehydrogenation efficiency is up to 100%, and complete dehydrogenation is realized; the dehydrogenation method and device are miniature, high-efficient, and safe.
Description
technical field [0001] The invention relates to ship ballast water treatment technology, in particular to a method for removing hydrogen in a ship ballast water management system and a device for implementing the method. Background technique [0002] In order to effectively control and prevent the spread of harmful aquatic organisms and pathogens in ships' ballast water, the International Maritime Organization (IMO) passed the "International Convention on the Control and Management of Ships' Ballast Water and Sediments" in 2004. The "Convention" stipulates that all ocean-going ships must treat ballast water in accordance with the timetable requirements, and retrospective implementation for existing ships. [0003] At present, many sets of ship ballast water management systems at home and abroad have been developed or are in the process of research and development, and electrolysis is a mainstream technology for ballast water treatment. During the operation of the electrolys...
