Abstract

The utility model discloses a glycerin separating device of biological diesel in the production process. The device is provided with a glycerin discharging pipe 2 at the bottom part of a reaction vessel 1 of the biological diesel, the glycerin discharging pipe 2 is connected with a glycerin separating tank 4 through a connecting valve 3, and a return pipe 5 of the biological diesel is arranged between the glycerin separating tank 4 and the reaction vessel 1 of the biological diesel. According to the actual conditions during the reaction process, the glycerin generated during the reaction process is discharged into the glycerin separating tank 4 with the fixed time and the fixed quantity or continuously, the balanced state of the chemical reaction is broken, so as to prompt the reversible reaction to move towards the direction where the biological diesel and the glycerin are generated, therefore, the conversion rate of the biological diesel can be improved to over 98 percent from 92 percent, the triglyceride content in the biological diesel can be reduced, the product color can be decreased, and the product quality can be improved.

Description

Glycerine tripping device in the production of biodiesel process

One, technical field

The utility model relates to the production equipment of organic Chemicals biofuel (fatty acid methyl ester), is specifically related to the glycerine tripping device in the production of biodiesel process.

Two, background technology

In the existing production of biodiesel, animal-plant oil or the animal-plant oil that contains small-amount free lipid acid are under catalyzer, excessive methanol environment, reflux, reaction generates biofuel and glycerine, and this chemical reaction belongs to reversible reaction, when the transformation efficiency of animal-plant oil biodiesel synthesis reaches 92% left and right sides, reversible reaction reaches equilibrium state, finish reaction, slough methyl alcohol, glycerine is separated from biofuel.Owing to do not adopt glycerine separation facilities separation of glycerin in the biofuel chemical reaction process, reaction is difficult to go on again when reaction is in reversible equilibrium state, influence the biofuel recovery rate, and content of triglyceride height in the biofuel, the biofuel quality influenced.

Three, summary of the invention

The purpose of this utility model provides the glycerine tripping device in the production of biodiesel process of a kind of biofuel transformation efficiency height, good product quality.

For realizing above purpose, glycerine tripping device in the utility model production of biodiesel process is established the glycerine discharge nozzle in biofuel reactor bottom, connect the glycerine separating tank by connecting valve, between glycerine separating tank biofuel reactor, also be provided with and the biofuel return line.

When the reversible reaction that is converted into biofuel and glycerine when grease and methyl alcohol under the effect at catalyzer reaches equilibrium state, from reaction system, isolate the glycerine of generation by the glycerine tripping device, break the equilibrium state of chemical reaction, impel reversible reaction to continue to carry out to the direction that generates biofuel and glycerine, the biofuel transformation efficiency can be brought up to more than 98% from 92%, reduce content of triglyceride in the biofuel, reduce product color, improve the quality of products thereby improve purity.

Four, description of drawings

Fig. 1 is the glycerine tripping device synoptic diagram in the utility model production of biodiesel process.

Five, specific embodiment

Below in conjunction with Fig. 1 and embodiment the utility model is described in further detail.

Glycerine tripping device in the utility model production of biodiesel process shown in Figure 1 is established glycerine discharge nozzle 2 in biofuel reactor 1 bottom, connect glycerine separating tank 4 by connecting valve 3, between glycerine separating tank 4 biofuel reactors 1, also be provided with and biofuel return line 5, because glycerine proportion larger part is beneficial to automatic separation in the reactor bottom, according to the reaction process particular case, at regular time and quantity or continuously the glycerine that generates in the reaction process is drained into glycerine separating tank 4 by valve 3, on a small quantity the biofuel that drains into glycerine separating tank 4 with glycerine is back to reactor 1 because of proportion is less by return line 5, realizes that glycerine separates automatically in the biofuel chemical reaction process.

Claims (1)

1. the glycerine tripping device in the production of biodiesel process, it is characterized in that: establish glycerine discharge nozzle (2) in biofuel reactor (1) bottom, connect glycerine separating tank (4) by connecting valve (3), between glycerine separating tank (4) biofuel reactor (1), also be provided with and biofuel return line (5).
