The device disclosed by the utility model not only effectively solves the problems of large equipment investment, high energy consumption and consequent increase of production cost caused by adopting a high-vacuum evaporation method in existing pretreatment of acid value of waste animal/vegetable oil, but also effectively solves the problems that a method of acid catalysis of the esterification reaction between fatty acid and methanol is low in fatty acid conversion rate and serious in methanol leakage and cannot reduce the acid value to an effective value.
Description
Technical field
The utility model relates to the biodiesel preparation equipment technical field, is specifically related to a kind of fatty acid ester gasifying device.
Background technology
Along with day by day minimizing and the fossil energy of oil stock in the worldwide are deepened day by day to the destruction of global environment, cleaning, Regeneratable biological diesel oil have obtained global attention.Biofuel typically refers to fatty acid methyl ester, is a kind of environment-friendly type petrifaction diesel substitute.But, expensive its large-scale development that hindered of biofuel.Cost of material is the key link in the biofuel cost, adopts the cheaply alternative fresh animal-plant oil of waste animal and vegetable oil, greatly reduces the raw materials cost of biofuel.Fatty acid content in the existing waste animal and vegetable oil is higher, must be reduced to the acid value of waste animal and vegetable oil below 0.5 by pretreated means.At present, prior art adopts dual mode to reduce the acid value of waste animal and vegetable oil usually, one, the method that adopts high vacuum evaporation lipid acid to reduce acid value can effectively reduce the acid value of waste animal and vegetable oil, but equipment manufacturing cost is high, energy consumption is large, is not suitable for economically; Two adopt the method for the esterification of acid (sulfuric acid, hydrochloric acid, tosic acid etc.) catalysis lipid acid and methyl alcohol, although the method energy consumption is lower, but conversion rate of fatty acid is low, and methyl alcohol leaks serious, the acid value of waste animal and vegetable oil effectively can't be reduced to below 0.5.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of fatty acid ester gasifying device, this technical scheme not only efficiently solves pre existing and processes waste animal and vegetable oil acid value employing high vacuum evaporation method, not only equipment investment is large, energy consumption is large, and energy consumption is large, the problem that causes production cost to rise, and efficiently solve the method for the esterification of acid catalysis lipid acid and methyl alcohol, conversion rate of fatty acid is low, and methyl alcohol leaks serious, acid value can't be reduced to the problem of virtual value.
The utility model is achieved through the following technical solutions:
A kind of fatty acid ester gasifying device, it is characterized in that: described esterification device comprises a kettle (2), the top of kettle (2) is provided with condenser (5), be provided with blocking valve (4) between kettle (2) and the condenser (5), kettle (2) is provided with opening for feed (3,6,7) near condenser (5) one ends, its opposite end is provided with discharge port (8), and the outside surface of kettle (2) is coated with heating jacket (1).
The further Technological improvement plan of the utility model is:
Described opening for feed (3,6,7) is respectively catalyst feeds, methanol feeding mouth and lipid acid opening for feed.
The further Technological improvement plan of the utility model is:
Described heating jacket (1) is coated on the outside surface of kettle (2) middle body.
The utility model compared with prior art, have following obvious advantage: the utility model equipment manufacturing cost is low, energy consumption is low, and reaction conversion ratio is too high, effectively solves methyl alcohol and leaks, the utility model is simple in structure, design science, cost are low, is convenient to promote the use of.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, esterification device described in the utility model comprises a kettle 2, the top of kettle 2 is provided with condenser 5, be provided with blocking valve 4 between kettle 2 and the condenser 5, kettle 2 is provided with opening for feed 3,6,7 near condenser 5 one ends, its opposite end is provided with discharge port 8, the outside surface of kettle 2 is coated with heating jacket (1), described opening for feed 3 is catalyst feeds, opening for feed 6 is the methanol feeding mouth, opening for feed 7 is the lipid acid opening for feed, and described heating jacket 1 is coated on the outside surface of kettle 2 middle bodies.
Sketch working process of the present utility model in conjunction with Fig. 1:
At first add lipid acid by opening for feed 7 toward kettle 2, add the industrial methanol that is equivalent to fatty acid wt 20% by opening for feed 6 toward kettle 2, be equivalent to fatty acid wt 3% catalyzer by opening for feed 3 toward kettle 2 addings, catalyzer is that weight ratio is sulfuric acid and the carbinol mixture of 1:1; Close opening for feed 7, opening for feed 6 and opening for feed 3; Then start condenser 5, blocking valve 4 and heating jacket 1, make that temperature of charge reaches 95 ℃ in the kettle 2, methyl alcohol seethes with excitement in kettle 2, and blocking valve 4 has controlled that methanol steam enters the flow of condenser 5 in the kettle 2, and allows the methanol liquid circulation in the condenser 5 enter kettle 2.Need not to install additional the stirring tightness system in the fatty acid ester gasifying device, thereby can effectively avoid methanol steam to leak.Because with the oscillating pressure of 0.1～3atm, under the effect of oscillating pressure, the transformation efficiency of lipid acid has obtained improving greatly, reacts after 3 hours in the kettle 2, the acid value of product reaches 0.2～0.3.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
