B, evaporation and concentration is processed: preheating liquid material inputs in evaporimeter (1c) by feed liquid feed tube (11), liquid level in separator (1d) reaches while setting liquid level, by raw steam valve (11b) to evaporimeter (1c) thus the raw steam of input makes liquid material explosive evaporation in evaporimeter (1c), then the indirect steam of liquid material explosive evaporation is delivered in separator (1d) by steam pipework (12), separator (1d) carries out gas-liquid separation to indirect steam, the separated indirect steam of separated device (1d) flows to cooler (1m) from condenser (1f), the indirect steam being cooled finally flows back in lime set tank (1e), incoagulable gas in lime set tank (1e) detaches by vacuum device (6), when indirect steam flows in condenser (1f) and cooler (1m), the liquid material of usining in material liquid tank (1a) is as low-temperature receiver, liquid material flows in the first feed liquid heat exchanger tube (21) and the second feed liquid heat exchanger tube (31) by the first feed liquid efferent duct (15), liquid material in the first feed liquid heat exchanger tube (21) is taken away the heat of the indirect steam in condenser (1f), after liquid material in the first feed liquid heat exchanger tube (21) is heated, flows in preheater (1b) and further heat, the indirect steam of being lowered the temperature enters in cooler (1m) simultaneously, then the liquid material in the second feed liquid heat exchanger tube (31) is taken away the heat of the indirect steam in cooler (1m), after being heated, liquid material in the second feed liquid heat exchanger tube (31) again flows back in material liquid tank (1a), moreover, from evaporimeter (1c), condensate liquid is out flow back in preheater (1b) and with the liquid material in preheater (1b) and is carried out exchange heat by condensate liquid recovery tube (41), by the condensate liquid of heat exchange, being become condensed water discharges from the solidifying water outlet pipe (43) of preheater (1b), the separated liquid material of separated device (1d) supplements pipe (51) by feed liquid and flows back in evaporimeter (1c), repeat the evaporation and concentration that above-mentioned step can complete liquid material.
10. the evaporating concentrating method of liquid material according to claim 9, it is characterized in that, in above-mentioned B step, in described separator (1d), be provided with liquid level meter (7), on feed liquid feed tube (11), be provided with the liquid feed valve (11a) being connected with liquid level meter (7); Described vacuum device (6) comprises vavuum pump (61), between described vavuum pump (61) and lime set tank (1e), by vacuum-pumping tube (62), is connected, and is connected with at least one vacuum valve (63) on vacuum-pumping tube (62).
