Embodiment Construction

[0034] The invention relates to an oil blending method and a blending device or equipment. The oil products suitable for blending in the method, device or equipment of the present invention include various conventional oil products in this field, such as gasoline, diesel oil, jet fuel, naphtha and light crude oil.

[0035] The oil product blending method of the present invention comprises: throttling and pressurizing the component oil products collected in the blending head and dividing them into 2 or more stocks, passing through 2 or 2 symmetrical pre-mixer container bodies respectively. More than two inlets are connected to the pre-mixer. After the material is fully contacted and pre-mixed in the pre-mixer, it enters the static mixer and mixes to form a qualified oil product.

[0036] In the present invention, 2 or more materials (such as 3 stocks, 4 stocks, 5 stocks or 6 stocks) enter the pre-mixer obliquely along the tangent direction of the pipe wall of the respective inl...

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 ...
