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 efficient static mixing device beneficial to oil blending and an oil blending method. The static mixing device comprises a premixer; the premixer comprisesa vessel body and two or more inlet joint pipes which are symmetrically arranged on the vessel body, wherein the two or more inlet joint pipes form included angles of 45-50 degrees with the axis direction of the premixer respectively, and the two or more inlet joint pipes are in liquid communication with the inside of the vessel body through inlets on the corresponding positions of the vessel body of the premixer. By adopting the method provided by the invention, component oil which gathers at a blending head is throttled and pressurized to form multiple strands of materials, and the materials enter the premixer through inlet joint pipes of the premixer respectively, are symmetrically sprayed into the premixer slantingly tangentially in a tangential direction of a pipe wall in a mode of ahigh-speed swirl and enter the static mixing device for further mixing after being fully contacted and premixed. The static mixing device provided by the invention can ensure that various component oils are efficiently and fully mixed, lowers the density layering and enables mixing of products to be 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 ...
