Crossing carries out mechanical compress to the steam for producing, to improve the temperature that the steam in contaminated water can be reapplied by heat exchanger,
So as to recycle to the heat of steam.MED and MVC are the method for evaporating for being most commonly used for distilling high-salt wastewater.MED and
MVC the two techniques the disadvantage is that, contaminated boiling water will be made, this can cause serious scale and etching problem, but also
Require expensive corrosion-and high-temp-resistant material.

It means that certain rising of air themperature is than needing more heats under low temperature at high temperature.On the other hand, water presents more
Many linear thermal capacity, it means that the amount of heat absorption needed for certain intensification is not remarkably dependent on the temperature of water.Therefore,
This expression thermal capacity of air in triangular web will be generally mismatched with the thermal capacity of water：In the low spot of TEMPERATURE SPECTROSCOPY, air heat
Capacity will be more much lower than the thermal capacity of water, and in the high point of TEMPERATURE SPECTROSCOPY, heat capacity of air amount will be more much higher than the thermal capacity of water.In view of
This humidification dehumidification system reduces air-flow or increase current to improve generally with the common liquid stream and air-flow through vapo(u)rization system
The heat exchanger effectiveness of TEMPERATURE SPECTROSCOPY high point will cause the deterioration of the heat exchanger effectiveness of the TEMPERATURE SPECTROSCOPY low temperature point, and vice versa.I.e.
Carrier gas mixture (mixed carrier gas) within the system or the liquid of flowing is made to change, such mismatch problem is still deposited

The temperature change during heat of amount is come exemplified with this case.Such as air temperature variations clearly visible by left figure, under low temperature
(curve is steeper) is faster than the air temperature variations (curve is less steep) under high temperature.Due to the thermal capacity of water it is temperature independent, therefore
Can all there is the temperature change mismatch caused by certain thermal energy exchange in the low temperature point and high temperature dot of heat exchange process, such as curve with
Shown in the gap at straight line two ends.In order to eliminate the temperature spread, external heat source and low-temperature receiver are needed, this improves the energy consumption of system.
Right figure shows this utility model with two evaporation/condensation units 1.By the flow velocity for being independently adjusted water in two systems
(high flow velocities of high temperature unit cause slope shallower, and the relatively low flow velocity of low temperature range causes steeper slope), the thermal capacity of water
It is preferably flux matched with the thermal capacitance of air, so as to improve heat exchanger effectiveness, and curve is substantially reduced with straight line two ends
Gap.The ability of water velocity is adjusted respectively it is meant that the thermal capacity of carrier gas mixture and the thermal capacitance of water are measured when temperature is raised

Part.
In some embodiments, by setting up separation gas scrubbing room by volatile material from the carrier gas mixture for circulating
Middle removal is favourable, and in gas scrubbing room is separated, fluid is optionally reacted with volatile material, so as to by the volatility
Material is removed from system.This will prevent these volatile material from being dissolved in distillate, it means that the distillate of generation will
Containing a small amount of pollutant, and can discharge or recycle without any further work-up.For example, when entering evaporation component
When 2 liquid contains ammonia, part ammonia will evaporate, and system is left together with distillate.Setting up makes the sulphuric acid H2SO4 and ammonia of circulation
Reaction forms the carrier gas mixture laundry room of ammonium sulfate (NH4) 2SO4 that individually can be removed reduces to can the ammonia in distillate
At least.
