Non-staining wall discoloring device for preparing epoxidizedepoxy soybean oil

Abstract

The invention discloses a non-staining wall discoloring device for preparing epoxy soybean oil. Because the hydrogen peroxide or alkali liquid entering the fixed box has the velocity of flow, the turbine impeller rotates, because the end of the output pipe is tangent to the inner wall of the decoloring box, so that the hydrogen peroxide or the alkali liquor can enter the decoloring box along the inner wall of the decoloring box, the hydrogen peroxide or the alkali liquor can be rapidly and fully contacted with the raw material of the epoxy soybean oil under the rotating state, and the reactionefficiency is improved; by the matching action of the annular body, the stirring paddle and the stirring plate, the epoxy soybean oil raw material and the hydrogen peroxide and the alkali liquor arefully homogenized, the reaction efficiency of the hydrogen peroxide and the alkali liquor on the epoxy soybean oil raw material is improved, the decoloring efficiency is improved, and the production efficiency is improved; due to the adoption of the liquid driving mode, the injection liquid and the driving rotating column only need an energy-consuming component output pump, so that the structure is simple, and the cost is saved.

Description

Technical field [0001] The invention relates to the technical field of epoxidized soybean oil processing, in particular to a non-stick wall decolorization device for preparing epoxidized soybean oil. Background technique [0002] Plasticizer is a polymer material additive widely used in industry. Adding this substance in plastic processing can increase its flexibility, make it easy to process, and can legally be used for industrial purposes. Taiwanese manufacturers use a common plasticizer DEHP (DINP, DNOP, DBP, DMP, DEP, etc.) to replace palm oil. The clouding agent can also produce thickening effects similar to emulsifiers. [0003] The existing traditional production process of epoxy soybean oil plasticizer mainly adopts alkali refining and refining, using concentrated alkali and low temperature process for refining. Affected by raw materials and processing conditions, the traditional process control conditions except for the main glycerin fatty acid In addition to the ester mi...

Problems solved by technology

[0003] The existing traditional production process of epoxy soybean oil plasticizer mainly adopts the method of alkali refining and refining, which is refined with concentrated alkali and low temperature process. Affected by raw materials and processing conditions, the traditional process control conditions are not only to generate the main glycerol fatty acid In addition to the ester mixture, there are also various impurities in different quantities, such as phospholipids, proteins, pigments, water, etc. The existence of these substances will undoubtedly affect the epoxidation reaction and product quality, and the removal rate of impurities under traditional process conditions is relatively low. Low, and the traditional equipment removal method mainly uses activated carbon or silica gel to remove directly in the tank, resulting in poor decolorization effect of epoxy soybean oil, can not improve the decolorization effect, and cannot fundamentally remove the pigment; and the raw materials are also It is easy to adhere to the inner wall of the box, which affects the product quality and makes it difficult to clean the box
