Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a purification device for fine chemical processing. Background Art

[0002] The polymerization process of petroleum resin is incomplete, leaving a large amount of reaction solvent. Therefore, the petroleum resin needs to be separated and purified at the end of production. Currently, the production process mainly uses flash evaporation technology. This technology takes advantage of the difference in boiling points between the solvent and the resin. By heating the resin solution, the solvent vaporizes due to its low boiling point, thereby removing the unpolymerized solvent and small molecular polymers in the solution.

[0003] Chinese patent publication number CN209438079U discloses a purification device for fine processing of petrochemicals. A driving motor is provided to drive the rotating shaft to rotate at high speed, thereby driving the inverted funnel to quickly move the petroleum resin. When the petroleum resin contacts the inverted funnel, it is thrown onto the side wall of the tank by centrifugal force. Because a heating plate is fixed on the tank, the difference in boiling points between the solvent and the resin is utilized. By heating the resin solution, the solvent vaporizes due to its low boiling point, and then an air pump is used to extract the gas to complete the separation. The multi-stage setting and sufficient contact of the centrifuge make the separation effect higher.

[0004] When the above-mentioned purification device is in use, the petroleum resin is dispersed by centrifugal force, and then the interior of the tank is heated by a heating plate to vaporize the solvent, thereby achieving a purification effect; however, the above-mentioned application cannot well ensure that the petroleum resin is completely dispersed by only using an inverted funnel. At the same time, since the petroleum resin is still relatively viscous after heating, the solvent inside the petroleum resin cannot be well vaporized, resulting in poor purification efficiency and certain limitations.
