| 摘 要： | 小型贯流锅炉具有效率高、节能、自动化程度高的特点,但对于给水水质要求也较高。与离子交换法相比,反渗透制水用于小型贯流锅炉给水时制水成本约5.04元/t,而离子交换的制水成本约2.83元/t,但反渗透的产水硬度、碱度、电导率都较离子交换水低,使锅炉的连续排污量和全排污量降低,从而节省了大量燃料费用,符合节能减排的要求。结果表明反渗透制水用于锅炉给水时,比离子交换制水更经济、操作更简单,应用前景广阔。

| Abstract: | The cost of ion exchange water,treatment for small tubular boiler feedwater is about 2.83 RMB/t.Compared with ion exchange water treatment process,the cost of reverse osmosis water treatment is about 5.04 RMB/t.However,the hardness,alkalinity and conductivity of reverse osmosis water is lower than that of ion exchange water,the boiler’s continuous water volume of blowdown and discharge are reduced,which saves a lot of fuel.The results show that reverse osmosis water treatment process for boiler feedwater has more superiority in economy with simple operation and wide application prospect. |
