Abstract

The invention belongs to the technical field of methanol-emulsified diesel production, and specifically relates to a single-reflection supergravity device and process for continuously preparing methanol-emulsified diesel, 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. High-gravity device, including impingement flow structure and rotating packed bed, the impingement flow structure is a non-limiting impingement flow structure, including main feed pipes and casings with different diameters and liquid baffles, the open end of the casing is connected to the main feed An annular seam is formed at the end of the pipe nozzle, and the impingement flow structure is arranged in the cavity of the rotor and along the direction of the rotor axis. process, the water phase and the oil phase with unequal volume ratios quickly complete the initial mixing through the collision of the impinging flow structure, 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 single reflection 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...
