Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
As shown in Figure 1; The water side of the dense water collecting tank of the utility model V101 is connected to the water-in of an effect preheater E101 through fresh feed pump P101; One imitates the water-in of the water outlet connection 1st effective evaporator E102 of preheater E101; The water outlet of 1st effective evaporator E102 is connected to the water-in of two effect well heater E103; The water outlet of two effect well heater E103 is connected to the water-in of 2nd effect evaporator E104, and the water outlet of 2nd effect evaporator E104 connects the import of condensing surface E105, and the outlet of condensing surface E105 is connected to water-freeing arrangement.
Said 2nd effect evaporator E104 bottom links to each other with the import of forcing discharging pump P102, forces to expect that the outlet of pump P102 is connected to the opening for feed of crystallization apparatus R101, and the discharge port of crystallization apparatus R101 is connected to receiving tank M101.The vapour outlet of said 1st effective evaporator E102 connects the steam inlet of two effect well heater E103.
As shown in Figure 2, its structure of crystallization apparatus R101 in the utility model includes housing 3, and transmission shaft 2 is installed on the housing 3, and driven by motor rotation axis 2 stirs in housing 3, quickens the sewage crystallisation by cooling.Sewage enters into housing 3 from water-in 1, in housing 3 outsides chuck 5 is installed, and water coolant gets into from chuck import 6, flows out from JO 7, to cooling off in the housing 3 again.The extraction line 8 of housing 3 bottoms is connected to receiving tank M101.
The working process of the utility model is following:
The utility model water inlet is the high density brackish water after two films of certain petroleum chemical enterprise's reusing sewage are handled, and presses Fig. 1 flow process; The dense water collecting tank of high saliferous V101 promotes entering under meter (control flooding velocity) through fresh feed pump P101, gets into one then and imitates preheater E101 to the dense water preheat of charging; Getting into 1st effective evaporator E102 again evaporates; The material of 1st effective evaporator E102 evaporation arrives certain temperature (～90 ℃) and vacuum tightness (0.035Mpa) time; Because the vacuum action material gets into two again and imitates well heater E103 heating; Evaporate in the heating back entering 2nd effect evaporator E104 (temperature-70c, vacuum tightness-0.09Mpa), 1st effective evaporator E102 evaporates the secondary steam that and supplies two effect well heater E103 to use; Because vacuum action, the solution entering two effect well heater E103 that 1st effective evaporator E102 evaporate heat once more and get into 2nd effect evaporator E104 and evaporate.Imitate in the evaporative process two, consider that two effect well heater E103 possibly give birth to fouling, therefore install one additional and force discharging pump P102 to carry out in good time discharging, avoid material to adhere to fouling to the inwall of heating tube in 2nd effect evaporator E104 bottom.And discharging is to mold R101, and crystalline solid gets into receiving tank M101, and filtrating is advanced suction filtration liquid bath V104 and returned prime by suction filter pump P104 and handle.The utility model evaporates the water and the vapour that to be passed through to get into liquid seal trough V103 behind the condensing surface E105, discharges through condensate pump P103 and recycles.
