Abstract

The invention belongs to the technical field of methanol-emulsified diesel production, and specifically relates to a continuous preparation of methanol-emulsified diesel with a river-shaped supergravity device and process, which solves the problem of large differences in material volume flow ratio in the existing methanol-diesel emulsion production process , The mixing effect is not ideal and the problem is uneven. The supergravity device includes an impingement flow structure and a supergravity structure. The impingement flow structure is a non-limiting impingement flow structure, including an auxiliary feed pipe I, an auxiliary feed pipe II and a main feed pipe; the main feed pipe nozzle and two The liquids ejected from the nozzles of the auxiliary feeding pipes meet at one point; the non-limiting impingement flow structure is arranged in the cavity of the rotor. process, the water phase and the oil phase are collided by an impinging flow mixer to quickly complete the initial mixing, and then enter the rotating packing to form a water-in-oil methanol diesel emulsion. The invention changes the impact form of the two-phase flow, improves the effect of the impact of the two-phase flow, and can simultaneously realize large-flow emulsion preparation and continuous operation.

Description

technical field [0001] The invention belongs to the technical field of methanol emulsified diesel production, and in particular relates to a Sichuan-shaped supergravity 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, a...
