Technique for continuous production of biological diesel oil with propagation waste oil

Abstract

The invention provides a technological method that utilizes the waste oil of animals and plants to continuously produce biodiesel. The technical proposal of the invention is that, waste edible oil, high acid value oil, animal and vegetable oils, oil foot and other components are used as materials; dehydration treatment, esterification and transesterification, methanol recovery, separation of fatty acid methyl ester and glycerol according to densities by a centrifuge, molecule distillation deacidification, high temperature decomposition of ester soluble impurity, and molecule distillation deodorization are directly performed; the finished product, which is light yellow fatty acid methyl ester, namely 0<#> biodiesel, is acquired by continuous production. The method continuously and rapidly semi-automatically completes esterification and transesterification reaction to get fatty acid methyl ester under completely vacuum condition at a certain temperature, and the problems of high production cost, low yield and long reaction time of biodiesel production by common esterification method are effectively solved. The invention has the advantages of no three wastes produced during the whole production process, green environmental protection, obviously lowered labor intensity, easy operation, low energy consumption, effectively reduced production cost of the biodiesel, fast reaction rate, improved productivity, and fitness for large scale industrial production.

Description

technical field [0001] The invention relates to a process method for continuously producing biodiesel from animal and vegetable waste oil. It uses waste cooking oil, high acid value oil, animal and vegetable oil, oil bottoms, etc. as raw materials to directly carry out dehydration treatment, esterification transesterification, methanol recovery, centrifuge separation of fatty acid methyl ester (biodiesel) and glycerin according to density, molecular distillation Deacidification, high-temperature thermal decomposition of ester-soluble impurities, molecular distillation deodorization, and continuous production of finished fatty acid methyl esters (ie 0 # biodiesel) process. Background technique [0002] With the progress of society and the development of science, human beings have higher and higher requirements for their own living space. Air and water pollution control has been mentioned in daily work as a must-solve course. During the "Eleventh Five-Year Plan" period, the...

AI Technical Summary

Problems solved by technology

It can effectively solve the problems of high production cost, low yield and long reaction time in the production of biodiesel by ordinary esterification methods and equipment. There are no three wastes in the production process, and it is green and environmentally friendly. The production process is continuous, the process is high, and the labor intensity is reduced. , increase yield, easy operation and low energy consumption, reduce production cost, increase productivity, suitable for large-scale industrial production
