Abstract

The invention discloses a continuous type solvent evaporation recycling device, and belongs to the technical field of grease processing equipment. The continuous type solvent evaporation recycling device comprises an evaporation tank, a solvent storage tank and a heat exchange structure, and is characterized in that the heat exchange structure comprises a primary preheating structure, a secondarypreheating structure and a plate type heat exchanger; an air guide pipe is of an inverted U shape, and a heat exchange pipe is arranged at the other end of the air guide pipe in the horizontal direction. The continuous type solvent evaporation recycling device has the beneficial effects that by arranging the air guide pipe and an oil pipe, the principle of reverse flow absorption is realized, andthe sufficient heat exchange is fully performed between crude oil and the solvent; by designing the two stages of preheating structure and the special flow distribution pipe, the unliquefied solvent steam in the air guide pipe further exchanges heat with the new grease through a spraying pipe, so that the heat exchange efficiency is greatly improved, thereby improving the grease and solvent separating efficiency; the air guide pipe is of the inverted U shape, and is higher than the height of the upper end port of the oil pipe, and the certain liquid level is maintained, so as to prevent the fluid from reversely flowing to the next layer.

Description

technical field [0001] The invention belongs to the technical field of oil processing equipment, and more particularly relates to a continuous solvent evaporation recovery device. Background technique [0002] Rice oil, also known as rice bran oil or rice germ oil, is obtained by deep processing of rice bran by solvent extraction and physical refining. Known as the real thing and rice gold in edible oil. [0003] However, the extraction and refining of rice oil requires a solvent. At present, leaching is carried out under medium temperature conditions, and then the solvent is recovered under high temperature conditions of negative pressure vacuum to obtain high-purity rice oil; this process requires multiple heating and condensation. Therefore, how to rationally utilize thermal energy and reduce the thermal energy consumption of the whole process is the research focus of rice oil deep processing technology, and the existing technology is also a relatively mature technology ...
