Description
Technical field
The utility model relates to the tail gas recycle of vacuum desolvation, is specially a kind of solvent classification recovery system of precipitation tail gas.
Background technology
In chemical production field, mainly by vacuum desolventizer, it utilizes the different boiling of different solutions to separate out needed material gaseous state in the recovery of solvent, reclaims liquid solvent by condenser, and reduces heating-up temperature by the boiling point of vacuum plant reduction solution.In this desolvation process, reclaim for the material demand that does not need to extract, especially organic substance has been avoided physical waste on the one hand, also can not cause environmental pollution on the other hand.To this, the rate of recovery of recovery system is very crucial.But the existing precipitation exhaust gas recovery system rate of recovery is low, causes physical waste, has improved production cost, can not satisfy existing demand.
The utility model content
The technical problem that the utility model solves is to provide a kind of solvent classification recovery system of precipitation tail gas, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of solvent classification recovery system of precipitation tail gas, comprise evaporimeter, vavuum pump, condenser and solvent recovery groove, described condenser is made of first-stage condenser, secondary condenser and three grades of condensers, link to each other by described first-stage condenser between described evaporimeter and the described solvent recovery groove, link to each other by described secondary condenser between described solvent recovery groove and the described vavuum pump, also be connected with described three grades of condensers behind the described vavuum pump.Described evaporimeter is thin film evaporator.
Beneficial effect
The utility model is simple in structure, and is easy to operate, and organic efficiency is high, and has reduced production cost, has guaranteed the Environmental security health.
Description of drawings
Fig. 1 is a kind of solvent classification recovery system schematic diagram of precipitation tail gas.
The specific embodiment
