Description

High-temperature and high-pressure water-displacement method recovery equipment for grease in vegetable oil waste argil

Technical Field

The utility model relates to the technical field of waste recycling, in particular to a high-temperature and high-pressure water-substitution method recovery device for grease in vegetable oil waste argil.

Background

In the process of refining and processing the oil, the non-ideal components in the oil need to be removed, and the safety and stability of the oil are improved. Generally, degumming and neutralization are carried out firstly, and then, clay is added for decolorization. The clay is added to remove phospholipid, pigment, various impurities and harmful substances in the grease, improve the color and luster of the grease and improve the stability. The clay is divided into natural clay and activated clay, the activated clay has larger specific surface area and stronger adsorption capacity, and can adsorb polar substances in the grease. Therefore, refineries typically use activated clay to refine edible oils. After the polar substances in the oil and fat are adsorbed by the clay and saturated, the adsorption capacity is lost, so that new clay needs to be replaced and used, and 2-4% of the clay of the oil and fat needs to be added for refining, so that a large amount of waste clay is generated in an oil and fat factory every year, the waste clay has no good treatment method at present and cannot be regenerated and used, and is generally buried after oil extraction, so that the environment is greatly polluted. The waste clay generally contains 20-30% of oil, so that the recycling of the waste clay not only can recycle clay resources, but also can extract 20-30% of oil and change waste into valuable, thereby not only protecting the environment, but also improving the utilization rate of the oil and fat.

The prior methods for extracting the waste argil grease in industrial production have two types,

1. the method adopts a high-pressure high-temperature pressing method, the grease in the waste clay is pressed out by a pressing machine and then is landfilled, and the method does not recycle the waste clay. And only half of the oil can be extracted by squeezing, most of the oil is still left in the argil, the used mechanical equipment is easy to damage, the energy consumption is high, and most of the workshop-type production operation environments are poor.

2. Adding argil into an extraction tank by adopting a solvent n-hexane extraction method, adding an n-hexane solvent into the extraction tank, wherein the mass ratio of the solvent to the waste argil is 0.5-1: 1, stirring and standing for 2-3 hours, filtering, leaching and extracting respectively by adopting an intermittent operation mode, and then recovering the solvent, wherein the operation of the method is discontinuous, the oil content of the leached waste argil is about 5 percent, and the waste argil cannot be recycled due to high oil content, so that the method cannot be popularized and applied in a large area.
