Abstract
The invention relates to a compact dehydrogenation device for a branch-electrolysis-process ship ballast water treatment system. The compact dehydrogenation device comprises a cyclone separator, wherein the top end of the cyclone separator main body is provided with a diluent hydrogen gas outlet and a diluent air inlet; the lower part of the cyclone separator main body is a cone, and the bottom end is provided with an electrolyte outlet; and the upper part of the cyclone separator main body is provided with a medium inlet. The device is characterized in that the lower part of the cyclone separator main body is immersed in a liquid collection tank; and the bottom of the liquid collection tank is connected with a ballast main port of a dosing pump. The test proves that when the actual operation flow rate is 70-130% of the rated flow rate, the separation efficiency of the dehydrogenation device can reach 90% or above, the operation is stable and reliable, and the problem of water spraying on the top gas outlet is solved, thereby completely conforming the requirements for the technical process of the branch ballast water treatment system.
Description
technical field [0001] The invention relates to a hydrogen removal device used in a branch electrolysis method ship ballast water treatment system. Background technique [0002] The electrolysis ship ballast water treatment device is installed in the ship's engine room, and the installation space is small. In order to ensure the safety of the ship, the ballast water dehydrogenation device must have a high separation efficiency. The state of the gas-liquid two-phase flow entering the dehydrogenation device will change greatly due to the difference in water quality and temperature, which puts forward more stringent requirements on the performance of the dehydrogenation device. The separated hydrogen needs ventilation for dilution, so it must be ensured that no liquid overflows from the gas outlet at the top of the cyclone separator. [0003] The traditional land-based dehydrogenation device used in the process of electrolyzing seawater mainly adopts the method of gravity sedi...
