Chemical conversion vapor enters gas phase, and the vapor after vaporization is taken away by high-power blower 901, to realize the evaporation and concentration of waste water.
Remaining waste water falls back to the cycle header tank 911 of base of evaporator, then is sent into spray system 905 by water circulating pump 910 and recycles
It uses.The water droplet carried secretly in air is stopped by water collection device 903, falls after rise in cycle tube still heater through in heating evaporation.Cycle
It is passed into high-temperature vapour in heating tubulation, high-temperature vapour enters cycle tubulation by coil pipe upper steam entrance, with cycle tubulation pipe
Outer spent shower water and air carry out heat exchange, and liquid is gradually condensed by gaseous state, export and flow out from lower steam, pass back into
Softening water tank.Meanwhile dry temperature higher air is entered by bottom inlet air grid 908 in tower (Fig. 2) under the action of wind turbine,
Or enter into air duct 918 (Fig. 3), the packing area of evaporator is entered after the heating of air dry combustion method pipe 919, waste water flows through filler table
Moisture film is formed when face and air carries out heat exchange, and the lower air of high humility temperature is extracted out from top, and waste liquid evaporates required
A heat part is conducted heat by air to be provided, and a part is heated by cycle tubulation and provided.Remaining water of waste liquid instills bottom cycle and catchments
In case.The waste water for instilling bottom cycle header tank is pumped into spray system again through water circulating pump, and water cycle is got up, and cycle sprinkling is useless
Water improves evaporation efficiency.In evaporator, the ratio of design treatment water and quantity of circulating water is 1:10, evaporation efficiency 50%.
Compared with the wind turbine used by the common evaporator of high-power blower used by this evaporator, difference lies in：Commonly
Only there are one drainages for the fan action of evaporator, only aspirate the steam in tower by wind turbine and draw evaporator；And
This evaporator uses high-power blower, can improve gas flow and gas flow rate in evaporator, and evaporation rate is empty with liquid level surface
Gas velocity is related, and air velocity is bigger, is more conducive to evaporate；And in this evaporator principle also with conventional evaporator different from,
The required energy of conventional evaporator evaporation is substantially all to be provided by heating tubulation, and an energy part needed for the evaporation of this evaporator
It is provided by heating tube, another part is provided by the higher air of enthalpy, can be saved heating energy consumption, therefore is also required to using more powerful
Wind turbine to provide the gas flow of bigger, but more common evaporator is greatly reduced on total energy consumption；Evaporator fan power needs
According to evaporator packing area height, designed rating size determines, evaporator outlet wind speed need to be ensured about in 12- depending on actual conditions
20m/s, exit wind speed when air outlet velocity is much larger than common evaporator operation.In energy consumption, common evaporator often evaporates 1kg water
The quantity of steam being actually needed is about in 1.2-1.6kg, and this evaporator often evaporates the quantity of steam that 1kg water is actually needed and about exists
0.6-0.8kg, this evaporator overall energy consumption are about the 50%-60% of common evaporator overall energy consumption, and specific effect regards live ring
Border temperature, humidity variation have certain fluctuation.
