Emulsifier precipitation separation device and system

The invention discloses an emulsifier precipitation separation device. The emulsifier precipitation separation device is characterized by comprising a precipitation bin, wherein the top of the precipitation bin is communicated with a liquid inlet pipe; the side surface of the precipitation bin is communicated with a liquid draining pipe; a slag discharging pipe is arranged at the bottom of the precipitation bin; a closed constant-temperature cavity is formed inside the side wall of the precipitation bin; a coiled pipe is arranged in the precipitation bin; two holes of the coiled pipe are respectively communicated with the constant-temperature cavity. An emulsifier precipitation separation system is characterized by comprising at least two emulsifier precipitation separation devices which are sequentially connected in series. The emulsifier precipitation separation device and the emulsifier precipitation separation system are simple in structure, are capable of quickly and effectively precipitating and separating sugar impurities in an emulsifier within short time, and are convenient to operate and good in separation effect.
