CN105480926A 一种用于储罐清洗的真空、加热、过滤三位一体罐装置 无效 - 驳回

一种用于储罐清洗的真空、加热、过滤三位一体罐装置
摘要：
本发明涉及石油钻井工具类技术领域，特别涉及一种用于储罐清洗的真空、加热、过滤三位一体罐装置。该装置包括：罐体，汽水分离罐，水环真空泵，汽水分离罐为水环真空泵提供工作液，通过水环真空泵出口管线对罐体内部进行抽空，使得罐体内部形成负压，将与罐体相连接的储油罐内的原油抽吸到罐体中，罐体内部设有加热盘管，所述加热盘管对罐体内的原油进行加热，罐体内还有过滤网，对加热后的原油进行过滤；罐体与离心泵相连接，所述离心泵将罐体内加热过滤后的液体进行抽吸并移送至指定地点。本发明提供一种用于储罐清洗的真空、加热、过滤三位一体罐装置，可有效提高机械清罐效率，并且能够最大程度保护离心泵，且提高对罐底油的回收率。
摘要（英）：

The invention relates to the technical field of petroleum drilling tools, in particular to a vacuum, heating and filtering trinity tank device for cleaning a storage tank. The device comprises a tank body, a steam water separation tank and a water ring vacuum pump, wherein the steam water separation tank provides working liquid for the water ring vacuum pump, the interior of the tank body is vacuumized through an outlet pipeline of the water ring vacuum pump, and therefore negative pressure is formed inside the tank body; crude oil in an oil storage tank connected with the tank body is pumped and sucked into the tank body, a heating coil is arranged in the tank body, the heating coil heats crude oil in the tank body, a filter net is further arranged in the tank body, and the heated crude oil is filtered; and the tank body is connected with a centrifugal pump, and the centrifugal pump pumps and sucks the heated and filtered liquid in the tank body and transfers the liquid to the designated place. According to the vacuum, heating and filtering trinity tank device for cleaning the storage tank, the mechanical tank cleaning efficiency can be effectively improved, the centrifugal pump can be protected to the maximum degree, and the recycling rate of tank bottom oil is improved.
