Low-pressure drop high-efficiency static mixing device and oil blending method beneficial to oil blending

Abstract

The invention relates to a low-pressure-drop high-efficiency static mixing device and an oil blending method that are beneficial to oil blending. The static mixing device includes a pre-mixer, and the pre-mixer includes a container body and two or more symmetrical Arranged inlet connecting pipes; wherein, each of the two or more inlet connecting pipes forms an included angle of 45° to 50° with the axial direction of the pre-mixer, and passes through the inlet at the corresponding position on the container body of the pre-mixer and The interior of the container body is in fluid communication. Using the method of the present invention, the component oil products collected in the blending head are throttled and pressurized into multiple strands of materials, which respectively enter the pre-mixer through the inlet joints of the pre-mixer, and the materials are tangential along the pipe wall in the form of high-speed swirling flow. The direction is diagonally tangentially and symmetrically sprayed into the pre-mixer, and after full contact with the pre-mixing, it enters the static mixer for further mixing. The static mixing device of the present invention can ensure efficient and sufficient mixing of various component oil products, reduce density stratification, and make product mixing more uniform.

Description

technical field

[0001] The invention relates to the field of production equipment for oil blending in oil refining enterprises, in particular to a low-pressure-drop, high-efficiency static mixing device and an oil blending method that are beneficial to oil blending. Background technique

[0002] Oil blending is the process of uniformly mixing two or more component oils in an appropriate proportion, so that the quality indicators of the oil produced after blending meet the relevant national standards or device requirements. There are currently two ways of tank blending and pipeline blending. Tank blending is to add the component oils and additives involved in the blending into the blending tank in order according to the blending ratio set in advance, and then mix them evenly by means of electric stirring and pump circulation to make them Become a refined oil that can meet the requirements of the production process. Pipeline blending is to use various automated equipment to ...
