Description

Technical Field

[0001] The utility model relates to the technical field of organic solvent drying, in particular to a high-efficiency flash evaporator. Background Art

[0002] Waste organic solvents can be refined using flash refining technology to make them into high-concentration organic solvents. The waste organic solvents need to be homogenized and then enter the flash kettle for heating. After the high-pressure saturated fluid passes through the pressure reducing valve and enters the flash kettle, the boiling point is reduced due to the sudden drop in pressure. At this time, the fluid temperature is higher than the boiling point under the pressure. The fluid will quickly boil and vaporize in the flash tank, and the flash tank provides space for rapid vaporization of the fluid and gas-liquid separation. For example, the production process of polypropylene is intermittent, and the reactor needs to be cleaned quickly and efficiently to prepare for the next production. This requires that the product can be quickly cleaned out. After flash evaporation, some organic matter in the existing volume will crystallize and adsorb on the inner wall of the flash tank, which will cause corrosion to the tank wall of the flash tank. Therefore, the flash tank needs to be cleaned frequently. Since the internal space of the flash tank is relatively large, the range that needs to be cleaned is also relatively large. It takes a lot of time for personnel to flush it, which is not convenient for quickly cleaning the residue on the inner wall of the flash tank and inconvenient to use. Utility Model Content
