Desulfurization wastewater is a kind of waste water produced by limestone - gypsum desulfurization method in coal-fired power plants. The annual output of desulfurization wastewater in China accounts for a high proportion of the total industrial waste water, and the harmful components in the wastewater are mostly supersaturated sulfites and heavy metals, so it is urgent to treat desulfurization wastewater.
Desulfurization wastewater treatment process usually includes physical treatment, chemical treatment, biochemical treatment, electrolysis treatment and so on.Our company adopts a plate evaporator for desulfurization wastewater treatment. The desulfurization wastewater evaporates and crystallizes in the evaporator. When the salt substances in the wastewater are saturated and crystallized, it enters the separator to separate the crystal liquid, and the mother liquid returns to the material pool, and the condensed water is discharged for reuse.
Advantages of plate type wastewater evaporator in desulfurization wastewater treatment:
1. Plate evaporator has high heat exchange efficiency and high utilization rate of hot steam, which can effectively reduce energy consumption, reduce operating cost and reduce steam consumption, thus saving processing cost for customers;
2. Under the premise of the same heat transfer area, the plate evaporator has compact structure and reasonable design, so as to reduce the small space occupied by the site area;
3. The plate evaporator heat exchanger has changeable circulation channels, which can realize self-cleaning function, and is not easy to scale, and will not cause the blockage of the whole flow passage.
Wintech is committed to design and fabricate various types of heat exchange equipments to meet the requirements of different industries like, steel making, coking, petrochemical, pharmacy, power plant,etc.
All the heat exchangers have below advantages:
1. High heat exchange efficiency, small floor space, easy installation and maintenance;
2. The surface of the plate is smooth, and the internal turbulence design of the curve avoids the energy waste caused by the increase of fouling thermal resistance and the decrease of efficiency;
3. Smooth flow passage, low running resistance, and lower running cost.It will greatly reduce the customer's energy waste and operating costs, with good environmental protection and economic benefits.
