System and method for guaranteeing oxygen supply on ship

Abstract

The invention relates to a system and method for guaranteeing oxygen supply on a ship. The method for guaranteeing the oxygen supply on the ship comprises the steps of: adopting an ionic transport membrane as a separating element to directly separate oxygen from oxygenic air; combining with combustion heat energy of a surface ship to produce oxygen by the ITM (Ionic Transport Membrane); and outputting oxygen to oxygen use points of various pressure sections. Therefore, the system can integrate efficiently and improve power generation efficiency of the conventional combustion gas turbine to 55%-65% (the efficiency of a conventional combustion gas turbine which adopts air as an oxidant is about 35%); and while fuel oil consumption is reduced, power output maneuverability of the ship is improved, and discharge of carbon and hydrogen is also reduced to reach to an environmental protection purpose. Meanwhile, no matter under any situation on the battlefield, including, nuclear-biological-chemical situation on the battlefield, oxygen outputted from the ITM oxygen production part is pure oxygen, so that technical indexes can be ensured to satisfy with the requirements of the conventional national standard and the conventional national military standard. The system and method for guaranteeing oxygen supply on the ship disclosed by the invention is applicable for oxygen source for guaranteeing oxygen which is used for medical treatment, vehicle-mounted devices and the like, and completely meets oxygen guaranteeing requirements of various pressure sections at each aspect of the surface ship.

Description

technical field [0001] The invention belongs to the field of air separation, and in particular relates to a ship oxygen supply guarantee system and method. Background technique [0002] At present, most surface ships adopt the traditional oxygen supply guarantee method, typically, mainly relying on the use of cryogenic air separation technology to produce oxygen at ports and bases, and then compressing and filling the oxygen with a supercharger, and then supplying it with oxygen cylinders However, it is obvious that the adoption of this method is subject to the transportation and replenishment conditions of oxygen cylinders, which brings a heavy logistical burden to the oxygen supply guarantee of long-distance ships. [0003] In recent years, there is also a method of directly installing pressure swing adsorption oxygen production equipment on medical ships to directly produce oxygen with a purity of about 93% on board for protection. However, the purity of oxygen produced b...
