| titleOfInvention | Seaweed fiber silk produces recovery process and the device of waste acetone dewatering agent |
| abstract | The present invention relates to a kind of medical seaweed fiber silk bandage and produce waste acetone dewatering agent recovery process and device, step is as follows: add thermal distillation to the waste acetone mother liquor from seaweed fiber silk dewatering tank, remove other organic compositions in waste acetone and impurity, add the heavy constituent of thermal distillation generation after ceramic membrane separation, permeate is back in seaweed fiber silk dehydrating step.Distillate is by pump input preheater and vaporizer, enter membrane sepn unit in vapour form, infiltration evaporation membrane separator group retains side and obtains the acetone finished product meeting processing requirements, and the purifying acetone obtained after dehydration enters seaweed fiber silk dewatering tank and reuses as dewatering agent.Infiltration evaporation membrane separator group per-meate side is connected with vacuum system, and vapor permeable enters rectifying tower process by after penetrating fluid condenser condenses, and tower top obtains the acetone containing a small amount of water, and enters acetone mother liquor tank, and waste water is discharged by the bottom of still.Present invention process process is simple, and safety coefficient is high, and facility investment is few, and capacity usage ratio is high, and whole set process floor space is little, and device height is low. |
