Title: Liquid thickening
Inventor: HARADA YOSHIAKI
IPC: C02F1/04
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a vapor compression type thickening technique of a small size and low equipment cost and running cost by using a screw type compressor for compression of the vapor generated in a thickening device. SOLUTION: The waste water to be thickened from a tank 1 is heat exchanged with the condensate from a line 18 in a preheater 5 and is put into an evaporator 8. A back pressure valve 7 is disposed between the preheater 5 and the evaporator 8 to make the internal pressure in the preheater 5 or the line 6 higher than the pressure in the evaporator 8 and to prevent the formation of air bubbles in the preheater 5. The liquid is uniformly dispersed, sprayed and droped in heat transfer tubes in a diffuser 9 through this back pressure valve 7. The generated vapor passes through a packed column 10 packed with packing materials, such as Raschig rings and/or filter media, such as active carbon, and is compressed and heated up by a screw type compressor 12.  This vapor heats and evaporates the liquid outside the tubes through the lines 13, 30 and from the inner side of the heat transfer tubes 14 of the evaporator 8. The vapor itself in the heat transfer tubes 14 is condensed and liquefied and the liquid accumulates in a condenser 16 where the liquid is heat exchanged with the waste liquid in the preheater 5 and is reused or released from a condensate tank 20. As a result, the foaming is suppressed by the thickening treatment with the small size and low cost.
