Description
Technical field
The invention belongs to technical field of waste water processing, and in particular to be concentrated by evaporation the spray of joint flue to a kind of vapor recompression
The technique of mist technical finesse waste water, for Waste Water From Fire Power Plant zero discharge treatment.
Background technology
MVR is the abbreviation of mechanical steam recompression technology (mechanical vapor recompression), is profit
The indirect steam and its energy produced with vapo(u)rization system itself, height is promoted to by mechanical work of low-grade steam through compressor
The steam source of grade.So circulate to vapo(u)rization system and thermal energy is provided, so as to reduce energy saving to one of the demand of outside resources
Technology.MVR technologies since 2007 from North America and Europe enter Chinese market, be mainly used in food deep processing, dairy
The industries such as conduct industry, Industrial Wastewater Treatment and beverage.MVR technical advantages:Add since indirect steam is constantly used as by compression circulation
Heat source, reduces unit ton consumption, energy-saving effect is obvious；Since evaporating temperature is low, the product residence time is short, is commonly used for temperature-sensitive
The evaporation and concentration of material；Overall floor space is few, and the degree of automation is high, and running cost is low；Technique is simple, easily maintenance；It is public
Conveyance system is few, and construction investment is small.
Thermoelectricity accounts for 80% or so in China's capacity of installed generator, has broken through 1,000,000,000 kilowatts, fired power generating unit based on fire coal,
With increasing substantially for installed capacity, thermoelectricity coal consumption ratio progressively increases.Coal is as a kind of low-grade fossil energy, its coal
Middle ash content and sulfur content are higher.The SO2 about 90% of China's discharge comes from fire coal, the acid deposition contamination hazard ecosystem and the public
