Oil-water separation device for production of plasticizer epoxy soybean oil

Abstract

The invention discloses an oil-water separation device for production of a plasticizer epoxy soybean oil. The separation device comprises a separation tank, a feed inlet, partition plates, cups, valves and a power pump. The upper left part of the separation tank is provided with the feed inlet. The partition plates are uniformly arranged inside the separation tank, and height of the partition plates is successively reduced from the left to the right. The upper part of each partition plate is uniformly provided with overflow holes. The bottom of each partition area inside the separation tank is provided with an outlet pipeline, which is successively provided with a cup and a pipeline valve. After converged, the outlet pipes are divided into two pipelines, namely a waterway pipeline and an oil-way pipeline. A waterway valve is installed on the waterway pipeline, and an oil-way valve and a power pump are mounted on the oil-way pipeline.

Description

technical field [0001] The invention relates to a production device of an organic chemical product plasticizer epoxidized soybean oil, in particular to an oil-water separation device for the production of a plasticizer epoxidized soybean oil. Background technique [0002] Epoxidized soybean oil is a widely used non-toxic, odorless polyvinyl chloride plasticizer and stabilizer. It has good stabilizing effect on light and heat, and has good compatibility, low volatility and small migration. The role in polyvinyl chloride plastic products is irreplaceable by other plasticizers. At present, epoxidized soybean oil is usually obtained as an epoxy plasticizer through the reaction of glacial acetic acid, hydrogen peroxide and soybean oil, and after the reaction is completed, it is neutralized, washed with water, and distilled to obtain the finished product. The traditional water washing process is carried out in a water washing pot. After washing, the material is left to stand to s...

AI Technical Summary

Problems solved by technology

However, the main problem is that the separation of oil and water in the water washing pot is not complete, and the drainage efficiency is low, which can easily cause material loss or high water content in the material, resulting in a heavy load on the subsequent distillation process, long distillation time, and waste of energy. At the same time, when the material temperature is too high, the epoxy bond Open-loop phenomenon occurs, seriously affecting product quality and product yield
