Embodiment
As shown in Figure 1; Furfural waste-water recycle device automatic control system; Comprise evaporating kettle 8, evaporator with external heating unit 1, steam separator 2, corrosion resistant water pump 3 and wastewater disposal basin 5, said wastewater disposal basin 5 is equipped with corrosion resistant water pump 3, and the water outlet of corrosion resistant water pump 3 is connected on the evaporating kettle 8; The top of evaporating kettle 8 is provided with the secondary steam outlet, and the bottom is provided with the wastewater outlet that is communicated with evaporator with external heating unit 1, and evaporating kettle 8 sidewalls are provided with the steam-in that is communicated with evaporator with external heating unit 1; The sidewall of evaporator with external heating unit 1 is provided with primary steam inlet that is communicated with boiler and the condensate outlet that is communicated with steam separator 2; Steam separator 2 tops are provided with the LP steam outlet, and the bottom is provided with the BW outlet.
For realizing automatic control; Its structure also comprises stopping valve 4, transmitter, liquidometer 9 and motorized valve 7; Said primary steam ingress is provided with stopping valve 4; Be respectively equipped with liquidometer 9 on the sidewall of steam separator 2 and evaporating kettle 8, the two ends up and down of said liquidometer 9 are separately installed with pressure difference transmitter 10; On the pipeline that BW outlet is connected, be provided with a motorized valve 7, said motorized valve 7 is connected with pressure difference transmitter on steam separator 2 sidewalls; Said corrosion resistant water pump 3 is provided with an electric controling switch, and described electric controling switch is connected with pressure difference transmitter on evaporating kettle 8 sidewalls.
The both sides of said motorized valve 7 are respectively equipped with a stopping valve; One manual pilot piping is connected in parallel on BW and exports on the pipeline that is connected; Said motorized valve 7 and stopping valve all export between two connectivity points of the pipeline that is connected at manual pilot piping and BW, and manually pilot piping is provided with a manually operated control valve.
Described corrosion resistant water pump 3 is provided with manual knob 6.
Described evaporating kettle 8, evaporator with external heating unit 1 and steam separator 2 are pressurized vessel.
Principle of work of the present invention is: control automatically under the operating mode; When hydrolysis process needs steam; Liquid level in the evaporating kettle 8 can descend, and the differential pressure pickup on evaporating kettle 8 sidewalls sends signal to the motor-operated control valve of corrosion resistant water pump 3, and corrosion resistant water pump 3 starts and begins in wastewater disposal basin 5, to draw water.
Waste water arrives evaporating kettle 8 under the conveying of corrosion resistant water pump 3; Discharge the heat transfer tube that gets into evaporator with external heating unit 1 inside from the wastewater outlet of evaporating kettle 8 bottoms then; The primary steam that boiler comes gets into evaporator with external heating unit 1 from the primary steam inlet and is the waste water heating; Waste water receives the thermogenesis secondary steam to get into evaporating kettle 8 from the steam-in, and the secondary steam outlet from evaporating kettle 8 discharges toward hydrolysis process then.
Part steam in the evaporator with external heating unit 1 and phlegma are discharged from condensate outlet and are got into steam separator 2, and the steam in the steam separator 2 discharges the process for refining toward the later stage operation from its vertical LP steam outlet, and fluid accumulation is in the bottom.When the liquid levels in the steam separator 2 arrived certain altitude, the pressure difference transmitter on its sidewall can send signal to motorized valve 7, and motorized valve 7 is opened, and the liquid in the steam separator 2 discharges toward boiler from the BW outlet.When the liquid level in the steam separator 2 was lower than certain value, motorized valve 7 can cut out automatically under the effect of pressure difference transmitter, left suitable liquid plays fluid-tight in steam separator 2 inside effect.
Manually under the control operating mode, the work of corrosion resistant water pump 3 relies on regulates manual knob 6, behind the manually opened corrosion resistant water pump 3, begins the work of drawing water.
The manual master mode of steam separator 2 discharge opeings is for all to close the stopping valve of motorized valve 7 both sides, and the discharge of liquid needs the manually operated control valve on the manual pilot piping of manual operation in the steam separator 2.
The present invention can full automatic control, complete manually control or combine automatically and manually, thereby system can judge that steam consumption confirms pump-out under the automatic control state, and the manual next needs of state of a control are artificially judged.Redundant system when in general, manual control mode goes wrong for the automatic control system parts.
