Description

The esterification device of environment-friendly type production biofuel

Technical field

The utility model belongs to a kind of biodiesel oil producing apparatus, and concrete is a kind ofly makes raw material with various animals and plants greases, carries out esterification with an acidic catalyst, and producing fatty acid methyl ester is the device of biofuel.

Background technology

Because a variety of causes, the fuel oil of various countries problem order benefit in short supply is serious, and the pollution of petroleum products is also more and more paid attention to by people, and therefore, greatly developing biofuel and various bio-fuel-oil is a very important task.At present, the technology and equipments about the production biofuel have appearred much, they all in various degree solution the basic fundamental problem of production biofuel.But come with some shortcomings mostly: must use stainless steel equipment, cost height; Use strong acid or alkali catalyst that environment is caused heavier pollution; Esterification is abundant inadequately, and transformation efficiency is not high; Adaptability to raw material is not strong; Production process control out of true, the quality of product is high inadequately.Therefore, it is more reasonable to need to propose a kind of structure, and equipment cost is low, and is free from environmental pollution, the technology and equipment that production efficiency and quality are high.

The utility model content

The purpose of this utility model is at the problems referred to above, proposes a kind of esterification device of environment-friendly type production biofuel, and this apparatus structure has bigger improvement, can make with plain carbon stool, use the weak acid solid catalyst, environment is not polluted, have and produce preferably and social effect.

The purpose of this utility model is achieved through the following technical solutions: a kind of esterification device of environment-friendly type production biofuel, comprise mainly and give esterifier and liquid divides phase separator that the described esterifier that gives mainly adds inlet by tank body, opening for feed, discharge port, electric mixer, heating unit, catalyst and forms; Described liquid divides phase separator mainly to be made up of tank body, opening for feed, discharge port, methyl esters outlet, glycerol outlet port; It is characterized in that: the described esterifier that gives also is provided with the flow deflector that is vertically fixed in inner tank wall, described tank base is taper, be provided with strainer in the middle of this conical lower portion, be connected to a compressed air inlet at described discharge port, catalyzer add the inlet and tank body between be provided with a batchmeter, described heating unit is formed by being located at jar intravital serpentine tube and water vapor import and steam outlet, with water vapor or hot water heating; Top at tank body also is provided with the methanol eddy device, and this device mainly is made up of distillation column and condensate cooler; The discharge port that will give esterifier by pipe connecting divides the opening for feed of phase separator to be connected with liquid.

The additional project of further improving and implementing of the present utility model is:

Described liquid divides phase separator also to be provided with every stream plate washer, light phase liquidometer and heavy phase liquidometer.

Described glycerol outlet port place is provided with an automatic escaper of glycerine, and this escaper mainly is made up of discharging glycerine optic cup, glycerine separator tube and switch.

The utility model is provided with vertical thrust-augmenting nozzle and pressurized air and adds the structure of strong mixing from the bottom injection, so can adapt to various raw materials owing to adopted steam or the serpentine tube structure of hot water heating, and stir, sufficient reacting, esterification turnover ratio height, good product quality; Adopted the catalyzer dosing device, the consumption of control catalyst more accurately, the methanol eddy device can better reclaim methyl alcohol; The bottom of taper and filtration unit can be controlled better and enter the quality that liquid divides the mixed solution of phase separator; Divide at liquid that be provided with in the phase separator can be so that the new mixed solution that injects can not mix with isolating glycerine and methyl esters every the stream plate washer, assurance methyl esters phase-splitting separating effect is better; Being provided with the glycerine automatic segregator can separate glycerine purelyr.Therefore, the utlity model has following advantage: adapt to various glyceride stocks; Use the plain carbon stool low cost of manufacture; Can use little acid catalyst free from environmental pollution; Esterification is abundant, and glycerine separates pure with methyl esters, and flow process is short, the transformation efficiency height, and the output high quality of production biofuel is good.
