Description
Technical field
The utility model relates to a kind of evaporimeter, specifically a kind of high effect forced circulating evaporator.
Background technology
The heating tube internal face produces fouling in the evaporimeter explosive evaporation process of prior art.So need be by adding a cover forced circulation device in the heating system of imitating in discharging, make that material flow reaches in the heating tube 〉=2.0m/s, reach the purpose of augmentation of heat transfer, so just make heat transfer efficiency obtain bigger raising, kept the flow at high speed of feed liquid in the tube bank simultaneously, the material that has also prevented crystallization adheres at the heating tube inwall, and then has stoped the generation of fouling to greatest extent.In order to reduce forced circulation pump power consumption, adopt an outer heater evaporation mode by tradition, be improved to two tandem mode of heatings, also reduce forced circulation pump 1/2 simultaneously and consume energy, reach equally that material flow reaches 〉=2.0m/s in the heating tube.The operation principle of this device can be widely used in the explosive evaporation crystallization processes of solution such as bittern, saltcake, potassium sulfate, sodium fluoride, caustic soda, sodium sulfite, manganese sulfate, common salt, barium chloride, calcium chloride, aluminium oxide, ammonium sulfate, ammonium chloride, sodium nitrate, sodium sulphate, magnesium sulfate, zinc sulfate.
The utility model content
A kind of forced-circulation evaporator that technical problem to be solved in the utility model provides at the existing in prior technology defective.To have the good explosive evaporation of augmentation of heat transfer, anti-scaling property and the advantage of forced-circulation evaporation combines.This device can be realized augmentation of heat transfer, can prevent that again the heating tube internal face produces fouling in the explosive evaporation process.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high effect forced circulating evaporator, its structure comprises vapour liquid separator, two heaters, and described vapour liquid separator top and bottom offer indirect steam outlet and high concentration material outlet respectively; Described two heaters are connected vapour liquid separator and form circulation with vapour-liquid two-phase outlet by the material solution import respectively.
Described vapour liquid separator middle-end connects a heater, and the heater lower end is connected with forced circulation pump, and the forced circulation pump discharge connects another heater; Described another heater upper end is connected with vapour-liquid two-phase outlet, enters vapour liquid separator.
Be connected forced circulation pump between described heater and the heater lower end, the heater upper end connects vapour liquid separator and becomes circulation continuously.
Its principle is, in normal evaporation and crystal process, material is oriented in a tangential direction from the vapour-liquid two-phase on heater top and spurts in the vapour liquid separator, makes to enter liquid phase after the vapor-liquid separation chamber in inwall formula decline form in the shape of a spiral, and vapour phase then rises to indirect steam.The crystalline solid proportion of separating out in the supersaturation feed liquid by evaporation is greater than mother liquor.The feed liquid that enters in the circulation pipe participates in strong circulation continuously by having a small amount of fine crystals in heater, the interior mother liquor, in order to prevent to produce fouling in the heater tube, mother liquor is under the big flow effect of forced circulation pump, the flow velocity of mother liquor in the heater tubulation reached 〉=2.0m/s, with the stagnation of avoiding heating tube inwall dirt and coalescent.High concentration material is under the promotion of discharging pump, and the bleeder valve of performing fighting carries out continuous discharging.
A kind of forced-circulation evaporator of the present utility model compared with prior art has following beneficial effect:
A kind of forced-circulation evaporator of the present utility model can be realized augmentation of heat transfer, can prevent that again the heating tube internal face produces fouling in the explosive evaporation process.By adding a cover forced circulation device in the heating system of imitating in discharging, make that material flow reaches in the heating tube 〉=2.0m/s, reach the purpose of augmentation of heat transfer, so just make heat transfer efficiency obtain bigger raising, kept the flow at high speed of feed liquid in the tube bank simultaneously, the material that has also prevented crystallization adheres at the heating tube inwall, and then has stoped the generation of fouling to greatest extent.In order to reduce forced circulation pump power consumption, adopt an outer heater evaporation mode by tradition, be improved to two tandem mode of heatings, also reduce forced circulation pump 1/2 simultaneously and consume energy, reach equally that material flow reaches 〉=2.0m/s in the heating tube.
Before not implementing this programme; As a heater heating surface (area) (HS 250m
2Pipe range 5m needs material flow to reach 2m/s in heater, required forced circulation pump discharge 2900t/h, Yang Cheng 2.5m, power of motor: 75kw.Year power consumption is 75kw/h * 0.70 yuan/degree electricity * 24 hours * 360 days=453600 yuan.
After implementing this programme; As a heater heating surface (area) (HS 250m
2Pipe range 5m needs material flow to reach 2m/s in heater, is split as two heaters, is exactly 125m so
2* 2=250m
2Required forced circulation pump discharge 1450t/h, Yang Cheng 2.5m, power of motor: 30kw.Year power consumption is 30kw/h * 0.70 yuan/degree electricity * 24 hours * 360 days=181440 yuan.
Not 181440 yuan=272160 yuan of/year saving electricity charge after the preceding 453600 yuan-embodiment of embodiment.
