Abstract
The utility model relates to sucralose solvent production equipment, and in particular relates to a special vacuum system for sucralose solvent recovery. The system comprises a recovery tank, wherein the recovery tank is connected with a vacuum pump through a gas-phase pipeline. The system is characterized in that the gas-phase pipeline connecting the recovery tank and the vacuum pump is sequentially provided with a first-level condenser, a second-level condenser and a third-level condenser; the first-level condenser, the second-level condenser and the third-level condenser are connected with the solvent recovery tank respectively; and the vacuum pump is a screw vacuum pump. According to the utility model, three levels of condensers and a dry vacuum pump are adopted, and then the problem of pollution caused by the solvent entering a vacuum system is solved.
Description
Technical field
The utility model relates to a kind of Sucralose solvent production equipment, specifically a kind of Sucralose solvent recovery Special vacuum system.
Background technology
In Sucralose was produced, being recovered in of various solvents accounted for very large ratio in the cost, for example: the recovery of ethyl acetate, DMF.The solvent recovery vacuum system of prior art generally adopts wet vacuum pump (normally water ring pump), and after reality was used a period of time, the solvent of solvent recovering system can enter in the water ring pump recirculated water, pollutes.
Summary of the invention
The utility model provides a kind of Sucralose solvent recovery Special vacuum system, and it adopts three grades of condensers and dry vacuum pump, has solved solvent and has entered the problem that vacuum system pollutes.
The concrete technical scheme that adopts of the utility model is:
A kind of Sucralose solvent recovery Special vacuum system, comprise recycling can, recycling can connects vavuum pump by the gas phase pipeline, it is characterized in that, the gas phase pipeline that is connected with vavuum pump at recycling can sets gradually first-stage condenser, secondary condenser and three grades of condensers, first-stage condenser, secondary condenser and grade condenser of being connected connect respectively solvent recovery tank, and described vavuum pump is screw-type vacuum pump.
Compared with prior art, the utility model has solved solvent and has entered the problem that vacuum system pollutes.
