Abstract

The invention relates to an oil product sequence conveying system and a method, and belongs to the field of pipeline conveying. The oil product sequence conveying system is used for sequentially conveying a plurality of oil product pipelines, and solves the problem that oil products are mixed in an existing oil product sequence conveying process. According to the technical scheme, the two ends ofa main pipeline are provided with a ball serving barrel and a ball collecting barrel, and when the oil product is conveyed, an oil product is conveyed into the main pipeline through the ball serving barrel and then the next oil product is conveyed; and after the pipe cleaning device arrives at a ball collecting cylinder, a storage tank and a pipeline corresponding to the oil return pipeline are switched, and the oil product at the rear end of the pipe cleaner is conveyed to another pipeline and a storage tank. The pipe cleaner isolates the conveying process and reduces mixing of two kinds of media on the oil mixing interface; and meanwhile, the pipe wall is scraped by the pipe cleaner, so that the residues of the front-end oil product on the wall surface of the pipeline are greatly reduced, and the mixing of the front-end oil product and the rear-end oil product is reduced.

Description

technical field [0001] The invention relates to an oil product sequential delivery system and method, which belongs to the field of pipeline delivery and is used for the sequential delivery of various oil products. Background technique [0002] As one of the main methods of crude oil transportation, pipeline transportation has the advantages of large transportation volume, automation, low energy consumption, low freight, airtight safety, and little impact on the environment and climate. During the sequential transportation of different oil products in oil pipelines, complex working conditions along the way will lead to mixed oil at the contact interface of adjacent oil products, and the treatment of mixed oil will increase pipeline operating costs. [0003] At present, the mixed oil treatment method is mainly to downgrade after blending, taking aviation kerosene transportation as an example. For aviation kerosene transportation, in order to ensure the quality of aviation ke...
