Description

Technical Field

[0001] The utility model relates to the technical field of sulfolene solution flash evaporation, in particular to a sulfolene solution flash evaporation device for sulfolene deep processing. Background Art

[0002] Flash evaporation is the phenomenon that when a high-pressure saturated liquid enters a relatively low-pressure container, due to the sudden drop in pressure, the saturated liquid becomes a part of the saturated steam and saturated liquid under the container pressure. In the deep processing of sulfolane, the sulfolane solution is often flash evaporated.

[0003] The existing flash evaporation device for sulfolane solution for deep processing of sulfolane generally adds sulfolane solution into a sulfolane solution storage tank, operates the relevant flash evaporation device to flash the sulfolane solution, then recycles the generated steam through the arranged condenser, and collects the remaining saturated sulfolane solution. Although the prior art can complete the flash evaporation of the sulfolane solution and achieve deep processing of sulfolane, in actual application, the prior art directly passes the sulfolane solution into the sulfolane storage tank. When there is too much liquid, the probability of contact between the internal sulfolane solution and the internal flash gas flow is reduced, thereby reducing the flash evaporation efficiency. In addition, during the flash evaporation process, when the pressure in the sulfolane solution storage tank is too high, the flash evaporation failure or the storage tank explosion is prone to occur. Therefore, we urgently need to improve a flash evaporation device for sulfolane solution for deep processing of sulfolane to solve the above problems. Utility Model Content
