Efficient reactor for production and processing of epoxy soybean oil

Abstract

The invention discloses an efficient reactor for production and processing of epoxy soybean oil. The efficient reactor comprises a reaction tank and a stirring device, wherein the reaction tank comprises an outer barrel and an inner barrel which are sealed; a cover body is hermetically arranged at an upper end of the reaction tank; an inner cavity body is formed between the outer barrel and the inner barrel; a steam coil pipe is arranged in the inner cavity body in a manner of surrounding the inner barrel; inclined feeding grooves are formed in opposite side surfaces of the cover body; a flow diversion plate communicated with the inclined feeding grooves is arranged in the cover body; the stirring device comprises a main stirring shaft; a plurality of transverse stirring shafts are equidistantly arranged on two opposite sides of the main stirring shaft from top to bottom; a plurality of stirring blades are arranged on each of an upper end surface and a lower end surface of each transverse stirring shaft in parallel; a plurality of conical stirring teeth are fixedly connected to two opposite sides of each stirring blade. The reactor is simple in structure and easy to operate, and can realize uniform stirring, uniform feeding and uniform heating, so that the production quality and the production efficiency of the epoxy soybean oil is improved and the economic benefit is increased.

Description

technical field [0001] The invention relates to the field of chemical equipment production, in particular to a high-efficiency reactor for production and processing of epoxidized soybean oil. Background technique [0002] It is a light yellow viscous oily liquid at room temperature, the solubility in water is <0.01 (25°C), and the solubility of water in this product is 0.55% (25°C), soluble in hydrocarbons, ketones, esters, higher alcohols, etc. Organic solvent, slightly soluble in ethanol. This product is the most widely used polyvinyl chloride non-toxic plasticizer and stabilizer: it has good compatibility with PVC resin, low volatility and small migration. It has excellent thermal stability and light stability, good water resistance and oil resistance, can endow products with good mechanical strength, weather resistance and electrical properties, and is non-toxic. It is an internationally recognized chemical process additive for food packaging materials . This prod...

Problems solved by technology

[0003] In actual use, epoxidized soybean oil still has problems of poor color and low quality, which is mainly related to the reaction of epoxidized soybean oil in the reactor. The existing reactors mainly have the following problems: Shortcoming, it causes the quality of epoxidized soybean oil is not high, one: the reaction process of epoxidized soybean oil is not stable enough, mainly related to the speed of adding ingredients, the speed of adding ingredients is too fast or too slow all can affect reaction effect, therefore , in order to obtain better quality epoxidized soybean oil, it is necessary to strictly control the feeding speed of the batching materials, not too fast; secondly, for preparations in the chemical field, stirring during the reaction is also one of the factors to obtain better products One, while the existing stirring settings are relatively traditional, only two stirring blades are used to complete the stirring reaction of epoxy soybean oil, which makes the stirring uniformity poor, which leads to the incomplete reaction of the produced product quality; thirdly, the environmental The reaction of oxygenated soybean oil needs to be carried out in a heated environment, because the increase of temperature can speed up the reaction speed and the reaction effect, while the steam in the prior art is directly passed into the reaction tank for heating. This heating method has an upper end Rapid heating, but the lower end is heated slowly, there is a temperature difference, resulting in the reaction of the upper end and the reaction of the lower end cannot be carried out at the same time, resulting in quality differences between the upper end and the lower end of the product
