At the cold wind import 101 of heater 1.
It should be noted that in the evaporation process method that the utility model implementation is related to;First by heater by sky
Gas is heated, heater use indirect heat transfer heater, heating agent can use conduction oil, hot water or other contain heat
The medium of amount, such as waste heat flue gas.As air is heated, the relative humidity of air is gradually reduced, and the air after heating is led to
Enter vaporization chamber, air is directly contacted with the waste liquid that vaporization chamber gets off from top spray, conducted heat and realize the heat absorption of moisture
Vaporization.Entering the waste liquid of vaporization chamber can be heated in advance, after hot dry air is contacted with waste liquid, the water in waste liquid
Divide the heat vaporization absorbed in dry air, so as to escape from waste liquid and form water vapour, air is due to absorbing moisture at this time
And form the damp-heat air of certain humidity.Damp-heat air, enters condensation from evaporator out under the driving of wind turbine
Device.Condenser can use direct or indirect heat exchanger, and refrigerant can use water at low temperature or other media, damp-heat air by with
Water at low temperature exchanges heat, and with the reduction of air themperature, relative humidity gradually increases in air, when reaching 100%, then air
In vapor then condense into water droplet so that from air out, so as to complete the removing of moisture.Air after cooling is from condensation
Device come out after under the driving of wind turbine, turn again to heater, be heated again, reduce humidity, be heated after air again
Drier is admitted to, circulation successively is gone down.
As the moisture in evaporator constantly evaporates, the concentration of pollutant gradually steps up in liquid, so as to reach concentration
Purpose.When the concentration of saline pollution material therein exceedes its saturated concentration, then its spontaneous nucleation forms crystalline particle.Crystallization
Salt then deposits to the bottom of vaporization chamber, and discharges evaporator by the facility of salt discharge, then by separation of solid and liquid facility by crystal salt
It is completely separated out from liquid.Indoor waste liquid is evaporated by the exterior continuous reciprocation cycle of circulating pump, i.e. circulating pump is from steaming
Send out the water suction of room bottom reservoir, the flusher being pumped at the top of vaporization chamber, waste liquid uniformly sprayed through flusher and
Under, conducted heat and evaporated with air during falling, unevaporated waste liquid then falls and is pooled to the liquid storage of bottom again
Groove, successively constantly circulation.During circulation, a degree of heating, heat can carry out waste liquid by a heat exchanger
Source can derive from waste hot steam, waste heat flue gas, conduction oil, hot water or heat pump system water outlet etc..
Within the condenser, since coolant media absorbs the heat of air and moisture in air condensation process is discharged
The latent heat come, therefore, can be according to physical condition to being used to heat, so as to achieve the purpose that energy saving of system.
