Title: Concentrating solutions by cooling and crystallisation - with alternate vibration of cooling surfaces and solution to prevent crystal adhesion
Inventor: BALDUS WOLFGANG DIPL PHYS DR
IPC: B01D9/00
Filed: 1976-06-04
Abstract: Solns. are conc. by using a heat exchanger to freeze out the crystallisable constituents. The heat exchange surfaces are alternatively vibrated relative to the soln. to prevent the resultant "ice" from adhering to the surfaces, pref. using differing frequencies. The heat exchange surfaces are pref. vibrated at a frequency of >=10, pref. >=30 Hz, while the soln. is vibrated at higher frequencies. Both sets of frequencies may be varied. By periodically stopping the vibration of the heat exchange surfaces, any cavitation produced in the cooling liq. by the vibration is allowed to disperse, so that the correct heat transfer and consequently the correct cooling takes place again. In addn, the use of a higher frequency of vibration in the liq. during this period assists in dislodging any ice particles which may be adhering to the surfaces.
