Description

Technical Field

[0001] The utility model relates to the technical field of oleic acid towers, in particular to an oleic acid tower for high-purity oleic acid. Background Art

[0002] Oleic acid is a monounsaturated fatty acid that exists in animals and plants. Pure oleic acid is a colorless oily liquid that is easily soluble in organic solvents such as ethanol, ether and chloroform, but insoluble in water. In the process of preparing oleic acid, it is necessary to use an oleic acid distillation tower to separate oleic acid from mixtures of different boiling points, specific gravities and volatilities to obtain oleic acid with higher purity.

[0003] According to Chinese patent announcement number CN219167731U, an oleic acid tower for high-purity oleic acid includes an oleic acid storage barrel, a distillation pipe, a connecting pipe, a cooling pipe, a guide pipe, a butt joint, and a support plate. The beneficial effect of the utility model is that the stock solution is heated by the oleic acid storage barrel in the oleic acid tower, so that the oleic acid in the stock solution is evaporated by heat, and is transmitted to the cooling pipe through the distillation pipe and the connecting pipe. At this time, the coolant flows into the internal cavity of the cooling pipe through the butt joint located at the bottom, and flows out from the butt joint located at the top. Since the volume of the internal cavity of the cooling pipe is larger than that of the guide pipe, the overall volume of the coolant is also larger than the oleic acid vapor in the guide pipe.

[0004] This announcement uses a heating wire set in the gap inside the oleic acid storage barrel to heat the raw liquid in the oleic acid storage barrel to evaporate the oleic acid therein. Since the heating wire is located inside the barrel body close to the wall, the liquid close to the barrel wall will be heated faster because it is closer to the heating wire, causing the liquid in the middle to be heated slower, resulting in uneven heating, which affects the evaporation efficiency. Therefore, an oleic acid tower for high-purity oleic acid is proposed to solve the above problems. Utility Model Content

An installation cavity 9 is opened inside the oleic acid tank 1, and an electric heating wire 10 is installed inside the installation cavity 9.

[0026] It should be noted that, by allowing the stock liquid to flow into the guide tube 15 from the liquid inlet pipe 2, and by driving the rotating shaft 13 to rotate through the driving motor 12, the guide tube 15 and the dispersion bucket 8 can be rotated, so that the stock liquid flows out from the liquid outlet 19 and falls on the surface of the dispersion bucket 8, and the stock liquid is dispersed on the inner wall of the oleic acid tank 1 through the rotating dispersion bucket 8, so that the stock liquid is evenly contacted with the inner wall of the oleic acid tank 1 and heated, and then flows into the bottom of the oleic acid tank 1, and then the stock liquid is stirred, so that the stock liquid is evenly heated.
