Control method for water quality of turbine auxiliary machinery cooling water
专利汇可以提供Control method for water quality of turbine auxiliary machinery cooling water专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent turbine auxiliary machinery structural materials from being corroded by cooling water by grasping the concns. of the nitrous acid ions, azide ions and nitric acid ions in the turbine auxiliary machinery cooling water and controlling the same to optimum concn. at all times. CONSTITUTION:The sample of turbine auxiliary cooling water is injected through an inlet 16 into a separating column 18, and the eluate in an eluate tank 12 is pumped 14 into a separating column 18. In this case, an aqueous soln. of perchlorate such as NaClO4 is used for eluate and strong basic anion exchange resins are beforehand packed in the column 18. The nitrous acid ions, nitric acid ions and azide ions in the cooling water of the sample are measured wavelengths enter the absorption cell of an ultraviolet absorption detector 20 near 200nm. The signals corresponding to the concns. of the nitrous acid ions, nitric acid ions and azide ions are generated by the absorption cell, and are quantitatively measured with a chromatograph. By the values thereof, the above-mentioned respective ion concns. in the cooling water are maintained at correct values.，下面是Control method for water quality of turbine auxiliary machinery cooling water专利的具体信息内容。
