技术领域technical field
本实用新型涉及一种用于海上平台的开排系统，属于海洋油气开发技术领域。The utility model relates to an opening and discharging system for an offshore platform, which belongs to the technical field of marine oil and gas development.
背景技术Background technique
开式排放系统是海上平台不可缺少的系统之一，它主要是用收集海上平台上与大气相通的雨水、污水和污油，这些流体经地漏收集后在开排罐中进行分离，分离出的污油通过开排泵打入闭式排放系统或生产系统中，收集的污水经处理达到排放标准后排入大海，以减少对海洋环境的污染。The open discharge system is one of the indispensable systems for offshore platforms. It is mainly used to collect rainwater, sewage and dirty oil that are connected to the atmosphere on offshore platforms. These fluids are collected by floor drains and separated in open discharge tanks. The separated The waste oil is poured into the closed discharge system or production system through the open discharge pump, and the collected sewage is discharged into the sea after being treated to meet the discharge standard, so as to reduce the pollution to the marine environment.
现有技术中，常规的开排罐通常为常压方罐，含水污油通过沉降方式在常压方罐内进行油水分离，在暴雨季节，短时间内可能会有大量流体进入开排罐，因此常规的开排罐较难达到预定的分离效果。当海上平台甲板上的固体杂质会同雨水或含油污水一起进入开排罐中，会通过静态沉降停留在开排罐底部，常规的开排罐一般是沿罐体的某一方向设置一定的坡度，以便于除去固体杂质，但是效果较差，尤其当开排罐体积较大时，基本无法完成在线除去固体杂质。In the prior art, conventional open-drain tanks are usually normal-pressure square tanks, and water-containing sewage oil is separated from oil and water in the normal-pressure square tank by sedimentation. In the rainstorm season, a large amount of fluid may enter the open-drain tank in a short period of time. Therefore, it is difficult to achieve the predetermined separation effect by conventional open-discharge tanks. When the solid impurities on the deck of the offshore platform enter the open drainage tank together with rainwater or oily sewage, they will stay at the bottom of the open drainage tank through static sedimentation. Conventional open drainage tanks generally set a certain slope along a certain direction of the tank body. In order to remove solid impurities, but the effect is poor, especially when the volume of the open tank is large, it is basically impossible to remove solid impurities online.
另外，当海上平台甲板面积较大或海上平台所处地区降雨量较大时，通常需要设计较大尺寸的开排罐及设置大排量的开排泵，以满足规范的需要，这样会造成设备投资多，占地面积大。In addition, when the deck area of the offshore platform is large or the rainfall in the area where the offshore platform is located is large, it is usually necessary to design a larger-sized open-discharge tank and install a large-displacement open-discharge pump to meet the requirements of the code, which will cause The investment in equipment is large and the floor area is large.
