Lower part connection, feed back pump outlet connected by pipeline with tank body sidepiece；The heat exchanger shell pass is connected with hot-water line.
Further, the tank body circular upper part is cylindrical, lower part is cone.
Further, the tank body is stainless steel.
Compared with prior art, the utility model is using evaporator, heat exchanger, solid particle filter, filtered fluid recycling
Bucket, circulating fan, feed back pump and circulating pump are combined mode, the waste water of required processing are entered in tank body by water inlet, so
ON cycle wind turbine afterwards, outside air can be inputted in tank body the evaporation efficiency for improving waste water by circulating fan, after then evaporating
Vapor and the outside air of input are discharged from gas outlet, while open the circulation pump, and close valve I unlatching, valve II
State, at this time waste water from tank base by circulating pump enter heat exchanger tube pass in, pass through hot-water line in heat exchanger shell pass at this time
The hot water after the completion of hot dip galvanizing process is conveyed, then hot water carries out heat exchange with waste water in heat exchanger, and the waste water after heating leads to
The outlet for crossing heat exchanger tube pass is sent back in tank body, so circulation, and the waste water temperature in tank body can be raised so as to accelerate waste water
Evaporation rate；With the progress of evaporation, the salt density in waste water gradually increases, until salt separates out when reaching supersaturation, this
When valve I closure, valve II be in opening, solid is transported to by salt and waste water mixture is separated out by circulating pump
Grain filter, after filtering solid salt stay in filter, the liquid after filtering enters filtered fluid recycling bin, then by time
Material pump is again fed in tank body, completes a separated process of waste water salt；Then passing through according to the above process repeatedly can be right
Waste water realizes the separation of salt；For the utility model by heating to waste water and drying waste water, both modes act on quickening at the same time
The evaporation efficiency of waste water, the afterheat hot water after in addition the heating of waste water is processed using galvanizing are heated, not only efficiently used
Remaining thermal energy, and be heated without the additionally consumption energy, so as to save the energy；Also point of the salt of the utility model
Carried out from process in solid particle filter, i.e., outside evaporator, so that the retention without solid salt in evaporator, therefore
It need not be cleared up before waste water evaporation next time is carried out, so as to improve the work efficiency of waste water evaporation.
