Abstract
A vacuum evaporator is provided with an integral cyclonic-type entrainment separator at the top of the evaporator vapor body which comprises a helical spin plate for imparting a centrifugal action to the vapor and entrained liquid rising from the boiling liquid in the flash chamber. Liquid entrainment is deposited on the vertical wall of the evaporator and flows downward countercurrent to vapor flow into a collecting trough, from which it is discharged into a pipe that returns it to the boiling liquid.
Claims24
In an evaporating apparatus comprising a vessel constructed to contain a pool of vaporizable liquid in the lower part thereof and having a side inlet for supplying make-up liquid to said pool, (b) a first connection for withdrawing liquid from the bottom of said pool and returning it to said pool via said side inlet, (c) a second connection for withdrawing liquid from said pool and passing it to storage or a second evaporator apparatus, and (d) a closed upper and, an entrainment separator comprising (a) a vapor exhaust pipe having a first open upper end within said vessel for receiving vapor evaporated from said pool and a second lower end communicating outside of said vessel, (b) means defining a helical path for conducting vapor evaporated from said pool to said first upper end of said vapor exhaust pipe and separating entrained liquid from said vapor by centrifugal action, and (c) means defining a trough for collecting liquid separated from said vapor.
