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...

Embodiment Construction

[0009] Use a Gr18Ni9Ti plate with a thickness of 14mm to weld a hydrolysis tower with a diameter of 1000mm and a tower height of 12000mm. A steam distributor 3 is installed at the bottom of the tower body 2. The steam distributor 3 is an arc-shaped plate structure, with the arc upward and the mouth facing Bottom, fixed on the inner wall of the tower body 2 by ribs 4, there is a gap around the bottom of the steam distributor 3 and the inner wall of the tower, and the outlet of the steam input pipe 6 is located below the steam distributor 3 and is perpendicular to the steam distributor. 3; the top of the tower body 2 is externally connected with a steam-water separator 7; The pressure inside the hydrolysis tower is designed to be 25kg / cm 2 .

[0010] The working principle of this hydrolysis tower is: first mix the oil to be hydrolyzed with one-third of the water, enter from the top of the tower, after the oil enters, turn on the steam, the steam enters from the bottom of the to...

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...
