The high density Nitrilon waste water treatment facility of present embodiment, work according to the following steps:
One, before starting outfit, the stoste A (high density Nitrilon waste water) in the former fluid cylinder 6 is input in the preheater 5 through pump.
Two, the bright steam that produces with the outside boiler of high density Nitrilon waste water treatment facility carries out preheating to it, vapor pressure 0.3MPa, and steam is about 500Kg; 66 ℃ of temperature; 30 minutes time, also can adopt electrically heated to replace steam heating, be 2 to 3 hours heat-up time.
Three, when in the preheater 5 during start vaporizer; In the Heat Room of stoste A in pump is admitted to first falling-film evaporator 1 of SS316 stainless steel; Stoste A mode with falling liquid film in Heat Room is evaporated; Steam output is 12 tons/hour, and then with stoste A with in the Heat Room in second falling-film evaporator 2 that is pumped into the SS316 stainless steel, evaporate with the mode of falling liquid film; Steam output is 7.8 tons/hour, and the stoste after evaporation is accomplished in second falling-film evaporator 2 is admitted to and rises membrane separation apparatus 10.
Four, the stoste A after separating is admitted to the Heat Room in the climbing-film evaporator 9 of SS316 stainless steel; In order to prevent the crystallization of inorganic salt in the solution; Adopt the mode that rises film to evaporate; Steam output is 200 liters/hour, reach predefined concentration after, liquid concentrator C squeezes into the liquid concentrator collection cylinder.
With falling film separator 10 with rises the secondary steam that membrane separation apparatus 11 separates and then is elevated to 74 ℃ from 66 ℃ through compressing; Squeezing into 5 li on interchanger then heats stoste A; This part vapor condensation Cheng Shui at the same time, its temperature is about 74 ℃, and condensation water quantity is 20031Kg/h.
Water of condensation with preheater 5 in former A liquid carry out heat exchange after, its stoste A temperature is heated to 55 ℃ from 30 ℃.
With preheater 5 in the temperature of the water of condensation of stoste A after carrying out heat exchange drop to 33 ℃ from 74 ℃.
After 55 ℃ stoste A get into preheating chamber, carry out the heat exchange evaporation with the secondary steam that is elevated to 74 ℃ through compression, whole high density Nitrilon waste water treatment facility system reaches thermal equilibrium, does not need this moment outside bright steam to heat.Only need the per hour 360Kw of vapour compressor to keep the thermal equilibrium of total system.
Liquid concentrator C in the high density Nitrilon waste water treatment facility system is discharged to concentrated fluid cylinder in falling film separator 10 with after rising the concentration that reaches design in the membrane separation apparatus 11 by pump.Do not circulate if reach design concentration then return again in the preheating chamber 5, the liquid concentrator C of 469kg/h through detect qualified after discharging.
The evaporation body of the horizontal tube bundle of the utility model is divided into 1,2,3 three parts and adopts single-stage steam vapour compressor, comes to overcome because of acrylic waste water because the rising boiling point of concentration rises increasing to influence of evaporation as far as possible.
In the preconcentration technique of the utility model; Need the stoste A that handles to carry out preheating through over-heat-exchanger and the water of condensation that evaporation produces; Stoste A after the preheating is imitated in the one falling-film evaporator one and is evaporated to 2% concentration from 0.8%; Material is evaporated to 24% by 2% in an effect disome, and material is evaporated to 35% by 24% in an effect trisome.
Imitate regeneration steam that trisome produces after mist eliminator is removed the fine mist that is mingled with in the regeneration steam by one, sucked compression back temperature by the MVR vapour compressor and get a promotion, the boiling point that is enough to overcome 35% acrylic waste water rises.Outlet at vapour compressor is a ultrahigh-temperature steam, utilizes a spot of zero(ppm) water B to spray into, as the usefulness of overheated cooling.This demister can be caught the drop in the steam get off and can not get into the zero(ppm) water B that heat transfer tube internal contamination system produces together with steam, zero(ppm) water B high purity, and vapour compressor can not bring possible etching problem because of a large amount of drops yet simultaneously.
Water of condensation in the pipe is collected into the distillation water pot, heats back discharge system through the distilled water pump pump to zero(ppm) water B heat exchanger liquid in future.After noncondensable gas in the steam and small amount of steam heated through vent condenser liquid in future, noncondensable gas was discharged system, guarantees system's operate continuously.
