Description
Technical field
The utility model belongs to desulfurization wastewater process field, and in particular to a kind of desulfurization wastewater zero discharge treatment flue and place
Reason system.
Background technology
Technique that existing desulfurization wastewater zero-emission engineering is applied, particularly domestic and international zero discharge of industrial waste water in recent years
Engineer applied, mainly using MVR vertical falling-films evaporation+fractional crystallization forced circulation salt manufacturing crystallizer+salt manufacturing dewaterer+drying+
Automatically the technical scheme packed.Desulfurization wastewater accomplishes 180000ppm after film is reduced, by the TDS of desulfurization wastewater, then highly concentrated
Salt solution enters evaporative crystallization technique, and according to heterogeneity in salt solution, the different of solubility crystallize out salinity at different temperature
Come, produce mixed salt, realize the zero-emission of waste water.The operation of this kind of desulfuration waste water treatment process is complicated, operating cost is high, technique not into
It is ripe, and salt caused by the process is NaCl and Na2SO4Crystal salt, purity is 98% or so, it is difficult to secondary use, can also be to ring
Secondary pollution is caused in border, belongs to dangerous waste, the processing cost of dangerous waste per ton is about 3000 yuan.
Although attempting desulfurization wastewater being sprayed onto in flue in the prior art, desulfurization wastewater is carried out using the waste heat of flue gas
Heating is evaporated, and remaining flying dust is caught by deduster and removed.But due to containing substantial amounts of moisture in desulfurization wastewater, if desulfurization
Waste water is evaporated not in time in flue, and when liquid is dropped in flue inner wall, burn into dust stratification or fouling are caused to flue inner wall, or greatly
The evaporation of amount moisture makes flue gas cool-down obvious, and low-temperature corrosion is caused to flue inner wall.If the drop of evaporation not in time is with flue gas
Into in follow-up equipment, in deduster, inevitably harm can be produced to follow-up equipment, influence equipment uses the longevity
Life.Also in order to solve the problem, attempt to carry out pre-concentration to desulfurization wastewater, then desulfurization wastewater be sprayed onto in flue again
Evaporation, still, the heat of one side desulfurization wastewater pre-concentration can expend certain energy, on the other hand, desulfurization wastewater pre-concentration
System be also required to larger investment, and then improve the processing cost of desulfurization wastewater.
In summary, existing processing cost is high during desulfurization wastewater zero discharge treatment in the prior art, easily produces
