| titleOfInvention | A kind of recovery system of ethylene glycol in waste liquid |
| abstract | The utility model discloses a recovery system for ethylene glycol in waste liquid, comprising: a first evaporation device is an evaporation device for recovering waste liquid, comprising a stock liquid evaporation tank, a stock liquid preheating device and two sets of condensation devices, wherein the stock liquid evaporation tank is Controllable constant temperature reaction vessel, the raw liquid preheating device is a coil type preheating device, the raw liquid is inputted by a peristaltic pump and preheated by the coil type raw liquid preheating device and then enters the raw liquid evaporation tank; the second evaporation device is a re-evaporation recovery device. It includes a wiped film evaporation device, a buffer tank and an exhaust gas condensing device. The buffer tank is a controllable constant temperature container, which is connected with the wiped film evaporation device through a valve and a peristaltic pump in turn. The system of the utility model can control the evaporation and separation process through the electrical conductivity, the ethylene glycol will not be oxidized by high temperature, the preheating device can quickly heat the raw liquid to the target temperature, the separation of the wiped film evaporation system is more efficient, and the system separation efficiency is high. The recovered ethylene glycol has high purity and can also achieve green recovery of precious metals. |
