The conventional recycle water field of mark design, which is compared, has both following advantage:
1, capital expenditure is saved, Circulating Water Field quantity of circulating water can decline 5% or so, and total investment cost reduces by 5% or so；
2, bottleneck is taken off, circulating water temperature is reduced, is kept the safety in production more secure；
3, water-saving, temperature reduction can reduce or no longer increase rate of water make-up when production in summer；Utilize blowdown evaporative cooling
When side stream, 5 ~ 8% or so rate of water make-up can be saved；
4, emission reduction, due to the reduction of quantity of circulating water, recirculated water VOC decline；When production in summer, outlet water temperature reduction can subtract
Increase blowdown flow rate less or no longer；It, can be with emission reduction 20% or so when using blowdown evaporative cooling side stream；
5, energy saving, 15% or more pump energy consumption can be saved.
