Description

Technical Field

[0001] The utility model relates to the technical field of chemical solvent purification, in particular to a novel petroleum benzene solvent purification device. Background Art

[0002] Petroleum benzene is a colorless, transparent, volatile, non-polar liquid with high refractive index and strong aroma of awn. It is flammable and toxic. The density is 0.879, the molecular formula is C6H6, the molecular weight is 78.11, the freezing point is greater than or equal to 5.40°C, the boiling point is 80.1°C, and it is soluble in many organic solvents such as ethanol, ether, acetone, carbon tetrachloride, carbon disulfide, etc., but insoluble in water. It emits a bright and smoky flame when burning. Its vapor forms an explosive mixture with air and explodes. Benzene is an important raw material for synthetic rubber, synthetic resin, synthetic fiber, synthetic medicine and pesticide. It can also be used as power fuel, coating, rubber solvent, etc. Purification refers to separating impurities from a mixture to improve its purity. Purification, as an important chemical method, not only plays an important role in chemical research, but also plays a very important role in chemical production. Many important chemical research and chemical production are based on purification. The entry introduces common physical and chemical purification methods in detail. Distillation is a thermodynamic separation process that utilizes the different boiling points of components in a mixed liquid or liquid-solid system to evaporate the low-boiling-point component and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation.

[0003] Application No. 201922436898.8 discloses a novel petroleum benzene solvent purification device, and its technical solution is that a support leg is fixedly installed on the lower surface of the box, a feed pipe is fixedly installed on one side of the box, a first funnel is fixedly installed on one end of the feed pipe, and a first control valve is provided on the outside of the feed pipe. The novel petroleum benzene solvent purification device stirs the novel petroleum benzene solvent inside the box by setting a driving motor, a rotating shaft and a stirring rod, so that the liquid solvent is distilled more fully and the distillation efficiency is improved. By setting a heat exchange device, a heating device and a condensing device, the novel petroleum benzene solvent can be quickly distilled when stirring the novel petroleum benzene solvent, so that the gas passes through the hollow rod to the condensation chamber for condensation, and the novel petroleum benzene solvent is quickly purified.

[0004] However, the stirring effect of the purification device is poor during use, which affects the distillation efficiency, and it is difficult to clean the inner wall of the box, which leads to impurities sticking easily during use. Therefore, we propose a new petroleum benzene solvent purification device. Utility Model Content
