According to the formula for temperature and pressure,forcertainvolume of the liquid, the lower the pressure, the lower the boiling point of the liquid.Low temperature vacuum evaporator is based on this principle, through reducing the internal pressure of the evaporator, improve the vacuum degree, reduce the Shaft boiling point of the liquid, and then improve the evaporation speed of the liquid.2.Dual use of cold and heat source for lowerenergy consumption
With theoperation ofrefrigerant compressor, while changingthe pressure and state ofOptical Fiber, Cable & Wire the refrigerant willchange its temperature.Control refrigerant exothermic heatingwhen in contact with the material, the refrigerantwill be cooling and liquidation, temperature drop.Then transfer the refrigerant to vapor condensing area through pipe.Using low temperature refrigerantto condensewater vapour, refrigerant absorb heat and gasificationagain and flow into the compressor for cycling. Such dual using of cold and heat source reduces theenergy consumption.3.The auxiliary cold and heat source ensures the balance of energy consumption of system evaporation and condensation
Low temperaturevacuum evaporator is operated under the condition of low temperature, it will be greatly influenced by the environment temPower Tools perature. When environment temperature is too low, itneedsmore energy forrefrigerant compressorto heatevaporation.But the cooling end itself are influenced by environmental temperature, the condensation temperature is low, it needsless energy consumption, such imbalanceenergy consumption increase the energy consumption of the compressor.
When in summer time with high environment temperature, the low temperature evaporator is more greatly influenced by environment temperature. High environmental temperature will cause compressor over load while condensing. But absorb too much heat to exhaustion and cause malfunction of compressor.
With patented technical control, our low temperature vacuum evaporator has fully considered the variation of environment temperature, and will start auxiliary cold and heat source to make sure the inner temperature is within control range, and the compressor will be operated within allowable range.Advantage of Low Temperature Vacuum Evaporator:Complete system with integrated design and fabrication, compact structure, space saving, easy installation, instant utilization only with connection of water and power supply.Low requirement on public supporting facility, without steam supply, complete with heat pump for circulation, cooling water is self generated by condensing water, no requirement for exterior cooling water supply.System operation stable and reliableEnergy saving, the running cost is much lower than traditional evaporatorLow requirement for pretreatment and after treatment, easy operation for complete process flowWater quality in low temperature is good for recycling and utilization.Completely automatic control with PLC system, applicable for unattended operation.With mobile equipment wireless remote control and monitoring, can realize instant getting the operation status of equipmentLow temperature evaporating is suitable for heat sensitive material without qualitative change, the concentrate can be recycled or treated by third party.
