Evaporating, concentrating is very typical chemical engineering unit operation in the industry, is widely used in industries such as oil, chemical industry, food, drying.The thermal source of evaporation and concentration operation mainly is to adopt the saturated vapor heating, and for the big material of concentration low processing capacity, the energy that steam expends is sizable; For the enterprise that needs outsourcing steam; Along with the rise of market steam price, enterprise's steam operating cost is increasingly high, how to reduce the operating cost of device; Energy savings, vast scientific and technical research personnel pay special attention to.The evaporation and concentration of the L-phenylalanine salting liquid of domestic enterprise mainly is to adopt the multiple-effect evaporation technology at present, imitates the indirect steam that evaporation produces before utilizing, and as the thermal source of back single-effect evaporator, but generally accomplishes triple effect, and evaporation effect is just undesirable behind the quadruple effect.As shown in Figure 2; It is a traditional triple effect evaporation flow process; In this technology, to give birth to steam and get into the first single-effect evaporator heating raw liquid, the indirect steam that evaporation produces gets into 2nd effect evaporator heating raw liquid as thermal source; 2nd effect evaporator evaporates the indirect steam that produces and gets into triple effect evaporator heating raw liquid again as thermal source, and heat exchange is condensed into the condensed water discharge between indirect steam entering condenser that the triple effect evaporator evaporation produces and the water for industrial use.Can find out that from above-mentioned multiple-effect evaporation flow process this mode need constantly provide a large amount of living steam, system's running cost is high; Simultaneously, the indirect steam of this last effect of mode needs the condenser cooling, needs to consume a large amount of industrial cooling waters, waste water resource; Also have, the required evaporimeter effect of the concentration number that multiple-effect evaporation technology completion liquid will reach regulation is many, and investment is big, and equipment is huge, complicated operation.For example,, evaporate 1 ton of water and approximately need consume 0.3 ton steam, and 1 ton of mark of coal-burning boiler burning coal produces 5 tons of steam approximately, evaporate 1 ton of water conversion coal consumption and be about 0.06 ton for traditional evaporation technology of a quadruple effect.The evaporation capacity of suppose device is 30t/h, and at present the market price of steam is 190 yuan/ton, then calculates by 300 7200 hours working days in 1 year, and the operating cost of steam is about 1,231 ten thousand, and is very uneconomical; Simultaneously, about 12960 tons of consumption coal, the 1 ton of coal that burns is according to chemical equation C+O
2=CO
2(molecular weight of C is 12, CO in calculating
2Molecular weight be 44), 1 ton of C burning produces 3.67 tons of CO
2, practice thrift 1 ton of mark coal and can discharge 3.67 tons of greenhouse effects arch-criminal gas CO less
2, burn 12960 tons of coals less, can produce 47563 tons of CO less
2, highly beneficial to environmental protection.
Evaporating concentration process is that a steam is by the process of high-grade to the very heat dissipation of low-grade conversion; Therefore; Low-grade indirect steam be utilized in the economy that has determined evaporation operation to a great extent; If can reduce the consumption of steam or need not give birth to steam, the energy of that saving is considerable, the economic benefit highly significant.A kind of L-phenylalanine salting liquid evaporation energy-saving equipment that the utility model relates to can reduce the consumption of steam in the evaporation process greatly, significantly improves economic benefit.
