Hydrolysis reaction tower for producing bio diesel fuel

Abstract

The invention relates to hydrolysis tower for biodiesel production. The bottom of tower is equipped with a steam distributor and fixed with rib to tower inner wall; there is space between all- around of steam distributor and tower inner wall, the outlet of steam inlet pipe is fixed below steam distributor; the top of tower is connected to a water separator; oil inlet is located on the top of tower, and the hydrolyized material outlet is at the bottom of tower. The invention is characterized by simple structure, easy production, high oil availability ratio of over 98.5%, increased biodiesel productivity by more than 30%, reduced production cost and environmental pollution, and increased industrial benefit.

Description

1. Technical field [0001] The invention relates to equipment in biodiesel production. 2. Background technology [0002] At present, the production of biodiesel in various countries in the world is mainly produced by chemical methods, but in the production of chemical methods, the method of transesterification is mainly used to produce biodiesel, so as to realize the refining of oils and fats by chemical and physical methods. Transesterification of refined oil and methanol. If the quality of oil refining is not good, the transesterification reaction will be affected and the conversion rate of triglycerides will be reduced. For example, the conversion rate of triglycerides in the production of biodiesel in the world is generally about 85%, that is to say, there are still about 15% neutral oils in biodiesel, and these medium-sized oils are mixed with methyl esters. It is difficult to vaporize in the cylinder of the car, resulting in carbon deposits, coupled with the existence...

AI Technical Summary

Problems solved by technology

[0003] If the oil is refined so that its acid value reaches below 0.2, and then undergoes transesterification reaction, the loss of oil will increase, and the general yield is about 70%, that is to say, 30% of the neutral oil will become oily waste. , and there is no mature process route for the production of biodiesel in the world at present, which causes the problem of lower oil utilization rate and higher production cost, and produces a large amount of oil feet to pollute the environment

[0004] If the neutral oil is hydrolyzed and then transesterified, the 30% oil bottoms produced during oil refining can be rationally utilized, but no one has applied the hydrolysis process to the production of biodiesel except the inventor , and the hydrolysis equipment currently used at home and abroad is not suitable for biodiesel production

The current hydrolysis equipment mainly includes stirring type and direct steaming type. These equipment not only require large investment, but also have long hydrolysis time and low hydrolysis rate.
