Problems solved by technology

[0008] In the above-mentioned transesterification process, since the transesterification reaction is a reversible reaction, excess alcohol can make the equilibrium move to the direction of the product, so the amount of alcohol is greater than the theoretical amount; there will be a large amount of unsubstituted alcohol in the reaction process; at the same time , the oil may also react incompletely and stay in the pipeline reactor. The waste of reactants such as alcohol and oil is serious, which increases the production cost and affects the product yield and purity.

Embodiment Construction

[0024] The core of the present invention is to provide a special equipment for preparing biodiesel. The special equipment adopts a new type of parallel pipeline reactor with multiple built-in parallel reaction tubes to realize efficient continuous transesterification reaction, and can react insufficient raw materials The collection of these raw materials automatically re-enters the exchange system, thereby improving the processing capacity of the equipment while avoiding the waste of reactants, reducing production costs, and improving product yield and purity.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Please refer to image 3 , image 3 It is a structural schematic diagram of a specific embodiment of the special equipment provided by the present invention.

Abstract

The invention discloses special equipment for preparing biodiesel. The special equipment comprises a reactor, a separator, a rectification tank and a return tank, wherein the reactor is provided with a catalyst filling opening for placing a catalyst; the feeding hole of the reactor is communicated with a material source, while the discharge hole thereof is communicated with the feeding hole of the separator; the discharge hole of the separator is communicated with the feeding hole of the rectification tank; the rectification tank is provided with a biodiesel outlet and a glycerol outlet; and the feeding hole of the return tank is communicated with the reactor, while the discharge hole thereof is communicated with the material source. In this way, the raw material which does not thoroughly react enters an ester exchange system again via the return tank and reacts again; therefore, the waste of the reactant is avoided, the production cost is reduced and the yield and the purity of the product are improved.

Description

technical field [0001] The invention relates to the technical field of biodiesel fine chemistry, in particular to a special equipment for preparing biodiesel. Background technique [0002] Biodiesel refers to fatty acid monoalkyl esters obtained by transesterification of animal and vegetable oils (fatty acid triglycerides) with alcohols (methanol or ethanol), the most typical being fatty acid methyl esters. Compared with traditional petrochemical energy, it has low content of sulfur and aromatics, high flash point, high cetane number, good lubricity, and can be partially added to petrochemical diesel. [0003] Biodiesel is mostly obtained by the traditional chemical transesterification method, that is, animal and vegetable oils and alcohols are transesterified under the action of a catalyst to generate fatty acid esters and glycerin. Special equipment is the main production equipment for biodiesel preparation, and its performance directly affects the quality and preparation...
