Description

Technical Field

[0001] The utility model relates to the technical field of membrane white oil extraction, in particular to a membrane white oil spray extraction device. Background Art

[0002] The traditional ultra-high molecular weight polyethylene diaphragm production process carries a large amount of white oil. After the production is completed, the white oil needs to be extracted with an oil solvent. The existing process uses tetrachloroethylene or dichloromethane as an extractant. Tetrachloroethylene or dichloromethane has a strong odor and a low flash point, which is easy to deflagrate. The loss in the air is also relatively large. After the extraction of tetrachloroethylene or dichloromethane extractants, it is necessary to heat and separate them from the white oil. A lot of energy will be lost, and a large amount of solvent needs to be condensed and recovered, which consumes a lot of energy. Based on this new white oil extractant, it has a smaller odor and a higher flash point. At the same time, the separation after extraction is carried out by liquid separation, and the energy consumption cost is low. Reduce energy consumption losses. As the country pays more and more attention to environmental protection. As the energy crisis intensifies, this solution has great advantages and prospects over traditional industrial solutions.

[0003] There is no professional technology and equipment for ionic liquid extraction of membrane white oil, and it is still in the exploratory stage. The original process is just simple immersion or heating immersion, which exposes problems such as unstable extraction effect and low efficiency. With the deepening of the experiment, it is urgent to overcome the above problems so that the new ionic liquid extraction technology can be widely promoted and applied.

[0004] Therefore, the utility model proposes a membrane white oil spray extraction device which adopts continuous and repeated strong spraying on the front and back sides to significantly improve the efficiency and extraction stability. Utility Model Content
