船舶压载水处理系统用旋流分离器气水分离技术

Gas-Water Separation Technology of Cyclone Separator in Ship Ballast Water Treatment System

电解法制次氯酸钠在船舶压载水处理产业中应用广泛,但是在产生次氯酸钠的同时会产生大量氢气,目前普遍采用旋流分离器对氢气和次氯酸钠溶液进行分离,但是传统旋流分离器分离效率较低。文章提供了一种对旋流分离器改进的方案,在不增加能耗的前提下提高溶液紊乱程度,通过对气体进行及时抽离降低旋流分离器内部压强,降低氢气在次氯酸钠溶液中的溶解度,从而提高气液分离效率。所提方案在不增加能耗的同时提高气液分离效率,可以为后期船舶压载水系统旋流分离器升级提供设计思路。

Electrolytic process is widely used in the ship ballast water treatment industry, but the Electrolytic seawater process will produce sodium hypochlorite and large amounts of hydrogen. The separation efficiency of hydrogen and sodium hypochlorite solution is low. The cyclone separation is widely used for Separation of hydrogen and sodium hypochlorite solution. A kind of improvement of cyclone separator is provided. It can improve solution disorder degree and the efficiency of gas and liquid separation without any increase in energy consumption. It can also reduce hydrogen solubility in the sodium hypochlorite solution by means of gas in a timely manner out of internal pressure. The scheme proposed in this paper can improve the gas-liquid separation efficiency without increasing the energy consumption, which can provide a design idea for the later upgrade of cyclone separator in ship ballast water system.
