Acidification oil-water purification energy-saving device

Abstract

The invention discloses an acidification oil-water purification energy-saving device, and belongs to the technical field of acidification oil-water purification. The acidification oil-water purification energy-saving device comprises an escalator device, a storage tank device, a water washing tower device and an oil-water separation tank device, wherein the storage tank device comprises a tank cover, a tank barrel and a first liquid conveying pipe, the bottom of the tank cover is in closed connection with the upper portion of the tank barrel, the bottom of the tank barrel is communicated with the first liquid conveying pipe, the water washing tower device comprises a water washing tower, a stirring device, a filter and a collecting barrel, and the bottom of the first liquid conveying pipe is inserted into the water washing tower. According to the invention, the problems that a traditional acidification oil-water purifying device needs a motor, consumes a large amount of electric power for stirring and cannot filter residues are solved. The invention relates to the production fields of vegetable oil, acidified oil, animal oil and the like.

Description

technical field [0001] The invention belongs to the technical field of acidifying oil-water purification, in particular to an energy-saving device for acidifying oil-water purification. Background technique [0002] Soapstocks are produced during the production of vegetable oils such as soybean oil. The production of acidified oil and biodiesel from oil soapstock is an important way of oil soapstock utilization. Acidified oil is essentially a fatty acid-containing oil, which contains pigments and unacidified triglycerides, diglycerides, monoglycerides (neutral oils) and other components. The fatty acids here are long-chain fatty acids, and the carbonic acid is generally between 12-24, of which 16-18 is the main one; depending on the source of oil, acidified oils have different distributions of saturated and unsaturated carbon chains. When the current acidified oil is washed with water, the acidified oil to be washed is usually mixed with water, and the water and oil are fu...

AI Technical Summary

Problems solved by technology

When the current acidified oil is washed with water, the acidified oil to be washed is usually mixed with water, and the water and oil are fully stirred and mixed by setting a corresponding stirring device in the mixing box, so that the water-soluble by-products such as inorganic acids in the acidified oil are dissolved. In the water, the acidified oil can be washed and purified by water, but the existing acidified oil-water purification devices generally require large-scale motors or other electromechanical equipment for traditional stirring. On the one hand, the stirring function is single and the effect is not obvious. A large amount of electricity, and the mixed liquid after stirring is generally directly separated from oil and water, but in actual production, due to the insufficient reaction between sulfuric acid and soapstock in the acidified oil, not only there are compounds such as inorganic acids, but also many large particles The impurities in the acidified oil make the purity of the acidified oil not enough. However, after the traditional agitated oil-water separation, the separated acidified oil still contains many large particles of impurities, and after the oil-water separation, the waste water is often discharged directly, and the water utilization rate is not high. Water consumption is high and pollution is large
