原油储罐搅拌器的设置？ 为防止原油储罐中沉淀物沉积,国外一些公司采用了皮托管射流器系统进行清渣除淤工作。皮托管射流器主要由连接法兰、主体、涡轮、喷嘴、机械主体等构成,其工作原理是被外循环泵压送的原油带动涡轮高速旋转,并同原油主流一起从喷嘴喷出,形成的高速射流随着喷嘴的旋转在罐底板上作360°周期性冲刷,使沉积物扩散到原油中随原油排出。采用皮托管射流器的优点是安全可靠,操作简单,不易形成射流死区,减少排水作业困难,便于实现海底(地下)储罐的清淤渣工作,并能缩短开罐检查的工期,降低清洗、防腐、动力费用,该系统与原油加热相结合还可取代加热盘管。 pilot pipe injectors are used by some foreign companies to prevent oil storage tank from silted up. the jnjector is made up of connecting flanges, main body, turbine, nozzel, mechanical unit, etc. the injector works following the principle as described below: the oil from the externally recycling pump drives the turbine to rotate at high speed, and is sprayed out together with main flow. the high speed jet flow thus formed, guided by the rotating nozzel, scours repeatedly on the tank bottom at an angle of 3... 文献名称 原油储罐清淤用的射流器 article name 英文(英语)翻译 the injector used for oil tank cleaning; 作者 王传曾; 陈向生; author wang chuanzeng;chen xiangsheng; 作者单位 author agencies 华东输油管理局工程管理处; 文献出处 article from 油气储运;;1995年 05期查看更多
