Pipeline quick-change filtering device for petroleum transportation and use method of pipeline quick-change filtering device

Abstract

The invention relates to the technical field of petroleum delivery, and particularly discloses a petroleum delivery pipeline quick-change filtering device and a using method thereof.The petroleum delivery pipeline quick-change filtering device comprises a petroleum delivery pipeline body and a quick-change box communicating with the middle section of the petroleum delivery pipeline body, and two filtering pipeline sections used for filtering petroleum are arranged in an inner cavity of the quick-change box; according to the pipeline quick-change filtering device for petroleum conveying, when the filtering pipeline section is cleaned, petroleum is output through the standby pipeline, at the moment, the filtering pipeline section is disconnected, the rotating disc rotates by 180 degrees, and the filtering pipeline section is replaced by the quick-change device. The filter pipeline sections on the left side and the right side are driven to replace positions, the filter pipelines can be rapidly replaced, in cooperation with vertical movement of the sealing sections, the sufficient sealing effect can be achieved while rapid replacement is conducted, leakage can be effectively prevented, and internal filter residues can be rapidly discharged through vertical shaking of the sealing sections; and manual cleaning is not needed.

Description

technical field [0001] The invention relates to the technical field of petroleum transportation, in particular to a pipeline quick-change filter device for petroleum transportation and a use method thereof. Background technique [0002] Crude oil is oil, also known as "black gold". It is customary to call unprocessed oil directly extracted from oil wells as crude oil. It is a dark brown or dark green viscous liquid or semi-solid combustible composed of various hydrocarbons. substance. There are oil deposits in parts of the upper crust. It is composed of a mixture of different hydrocarbons, the main components of which are alkanes, in addition to sulfur, oxygen, nitrogen, phosphorus, vanadium and other elements in the oil. Soluble in various organic solvents, insoluble in water, but can form emulsion with water. According to the density range, it is divided into light crude oil, medium crude oil and heavy crude oil. However, the composition and appearance of oil in differ...
