Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, plant electroplating wastewater evaporation concentration device, comprise the separator 8 for gas-liquid separation; Be arranged at separator 8 lower end and the well heater 10 be communicated with it; Be arranged at the floatation device 12 be communicated with bottom well heater 10 and with it; The overboard pump of the underflow in floatation device 12 being discharged is communicated with floatation device 12; Be arranged at the condenser 5 of separator 8 side for condensed steam, described condenser 5 is communicated with by condenser tank railway carriage or compartment 6 with between separator 8; Be arranged at condenser 5 lower end for collecting the condensate water pot 4 of water of condensation; Be communicated with condensate water pot 4 and the condensate pump 3 that water of condensation is exported.
Described device also comprises the vacuum pump 2 for vacuumizing in system, and described vacuum pump 2 is communicated with condenser tank railway carriage or compartment 6.
Described separator 8 is provided with blow-down pipe 7.
Described well heater 10 is communicated with expander 9, and described well heater 10 is electric heater 10, and electric heater 10 is provided with electric heating tube 11.
Described each structure and parts are all controlled by PLC.
Also comprise the electrical control cubicles 1 for controlling.
During use, opening vacuum pump 2 makes system form vacuum state, open the water coolant turnover valve of condenser 5 simultaneously, electrical control cubicles 1 sets heating schedule, separator 8 is entered after the stoste metering of normal temperature, heating unit is opened when feed liquid reaches working level, start to carry out heating evaporation to feed liquid, start when feed liquid reaches 60 DEG C to evaporate (vacuum tightness-0.08Mpa), the liquid-vapor mixture produced during evaporation carries out vapor-liquid separation in separator 8, secondary steam enters condenser tank railway carriage or compartment 6 after rising, water is condensed into after condenser 5, collect in condensate water pot 4, the water of condensation that evaporation produces gets to reuse in electroplate technology by condensate pump 3.The underflow produced after evaporation enters in floatation device 12, is discharged by discharging pump 13.
When this apparatus design, fully take into account a difficult problem for inorganic salt, organic fouling and clogging, so adopt the Steaming structure of band floatation device 12, such design has following beneficial effect:
1, short circuit temperature difference loss is little, crystal growth district and crystal negative area are separately, enter well heater 10 and carry out the hydronic solution being a cancellation degree of supersaturation, its crystalline content is few, not easily formed and scab, both suppressed a nucleation rate, increase crystal mean particle size, slow down again evaporator room inwall salt crust speed, extend the cleaning interval; 2, the crystal amount in circulation feed liquid is few, and especially coarse-grain amount is less, decreases the collision opportunity of crystal and pump impeller, reduces secondary nucleation speed; 3, feed liquid heat up that the thin brilliant solvency action that produces is more effective 4 through well heater 10, inorganic salt crystal classification in floatation device 12 of separating out, washing and thickening, the temperature of discharging salt slurry is reduced, decrease thermosteresis, and alleviate the corrosion to follow-up equipment; 5, in interchanger, velocity flow profile is even, to avoid larger velocity slope, guarantee uniformity of temperature profile (as traverse baffle district), ensure rational Pressure Drop and do not cause corrosion prerequisite under, improve flow velocity to contribute to reducing dirt (evaporating under vacuum conditions, temperature when improving the flow velocity of feed liquid and reduce evaporation); 6, adopt minimum dead band and low flow velocity district during design, this device is highly polished with material contact site, and resistance little (improving the smooth finish of tube wall and tank skin), makes dirty layer not easily be formed, and have strong souring to dirty layer.Efficiently solve fouling and blockage problem that high salinity in electroplating wastewater, high organism cause heat-transfer surface.
The control of this device requires the PLC full automatic control two kinds of Non-follow control and man-machine interface according to user.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
