Double-spiral-pipeline oil mixing method and double-spiral-pipeline oil mixing device

Abstract

The invention discloses a double-spiral-pipeline oil mixing method and a double-spiral-pipeline oil mixing device. The device mainly consists of a sleeve and an inner pipe, wherein the inner pipe is arranged in the sleeve, the outer diameter of the inner pipe is equal to the inner diameter of the sleeve, and the outer wall of the inner pipe is completely fitted with the inner wall of the sleeve; the inner wall of the inner pipe is provided with threads including clockwise rotating threads and counterclockwise rotating threads, and the clockwise rotating threads are connected with the counterclockwise rotating threads. The device provided by the invention is simple as well as simple and convenient to operate; by clockwise and counterclockwise twisting an oil product, flowing in an oil conveying pipeline, along the opposite directions, the oil product is subjected to forward and reverse intense turbulent flow and to be fully mixed, so that the mixing effect of the oil product is improved.

Description

technical field [0001] The invention relates to the technical field of oil pipeline mixing, in particular to a double helix pipeline oil mixing method and device. Background technique [0002] With the increase of domestic vehicle usage and oil demand, while domestic oil production is less, my country imports more and more oil, and more and more countries and regions import oil sources. The physical and chemical properties of different oil products The difference is large; for refineries, it is necessary to adjust different production parameters for each crude oil refined, which brings great difficulties to refinery production. Moreover, for the refined oil obtained after refining, it is also faced with the blending of different quality oil products. [0003] In order to adapt to different oil products in different countries and regions, it is necessary to mix and blend different oil products from different regions before refining. There are various mixing methods; generally...

Problems solved by technology

[0003] In order to adapt to different oil products in different countries and regions, it is necessary to mix and blend different oil products from different regions before refining. There are various mixing methods; generally there is a mixing method in a storage tank, but mechanical stirring and other equipment are required method, consumes a lot of power and energy, which is not conducive to energy saving and consumption reduction
