Problems solved by technology

The defect of this method is: alkali refining is to fully mix crude oil and alkali, because the obtained crude oil contains flammable and explosive solvents such as n-hexane and methanol, there may be the possibility of solvent volatilization when crude oil and alkali are mixed, There are high safety hazards in the production process, and the mixing process requires additional power and high energy consumption

Abstract

The invention discloses a static mixing device for oil and alkaline. The static mixing device is characterized by comprising a tank body A (1), a mixed-oil feeding pipe (1-1), an alkaline-liquid feeding pipe (1-6) and a mixing chamber B (1-4), wherein the mixing chamber B (1-4) is arranged in the tank body A (1); a mixed-liquid seepage hole (1-5) is arranged in the surface of a shell of the mixingchamber B (1-4); an inner cavity of the mixing chamber B (1-4) is communicated with an inner cavity of the tank body A (1) by the mixed-liquid seepage hole (1-5); an outlet end of the mixed-oil feeding pipe (1-1) is arranged in the mixing chamber; at least one section of alkaline-liquid feeding pipe (1-6) is arranged in the mixed-oil feeding pipe (1-1), and the part of the alkaline-liquid feedingpipe (1-6), placed at the mixed-oil feeding pipe (1-1), is provided with an alkaline-liquid seepage hole (1-2).

Description

technical field [0001] The invention relates to an oil-alkali static mixing device and a method for preparing cottonseed refined oil from cottonseed mixed oil by using the device. Background technique [0002] At present, when cottonseed is processed, the obtained mixed oil usually adopts the processing method of two evaporations and one desolventization to obtain cottonseed crude oil, and then the cottonseed crude oil is refined by alkali and dried to obtain cottonseed tertiary oil. The defect of this method is: alkali refining is to fully mix crude oil and alkali, because the obtained crude oil contains flammable and explosive solvents such as n-hexane and methanol, there may be the possibility of solvent volatilization when crude oil and alkali are mixed, There is a high potential safety hazard in the production process, and the mixing process requires additional power and high energy consumption. [0003] Therefore, a static mixing device with simple structure, high mix...
