Abstract

The invention belongs to the technical field of production of methanol emulsified diesel fuel, particularly relates to a device and a process for continuously preparing methanol emulsified diesel fuel, and solves the problems of non-ideal and non-uniform mixing effect under the condition of larger material volume flow rate differences in conventional methanol emulsified diesel fuel production process. The supergravity device comprises an impinging stream structure and a rotating packed bed, wherein the impinging stream structure adopts a non-restrictive impinging stream structure and is arranged in a cavity of a rotor and arranged in the axis direction of the rotor. According to the process, an aqueous phase and an oil phase whose volume ratios are different are rapidly and preliminarily mixed through impinging of the impinging stream structure and then enter high-speed rotating filler to form water-in-oil type methanol diesel emulsion. According to the device and the process, the impinging form of two-phase flow is changed, the impinging effect of the two-phase flow is improved, and meanwhile, high-flow emulsion preparation and continuous operation can be realized.

Description

technical field [0001] The invention belongs to the technical field of methanol emulsified diesel production, and in particular relates to a device and process for continuously preparing methanol emulsified diesel. Background technique [0002] Due to the increasing shortage of petroleum resources, rising prices and increasingly serious environmental pollution, the development of low-emission oil substitute fuels has attracted the attention of countries all over the world, especially the research on alcohol fuels has always been one of the topics of great concern to the majority of scientific and technological workers. Among the many alternative fuels, methanol has attracted more and more attention in the application research of alternative fuels for internal combustion engines due to its abundant resources, reasonable price, easy preparation and good physical and chemical properties. The reason lies in my country's advantages in coal resources, and the development of coal-b...
