Description
Technical Field
The invention belongs to the technical field of circulating cooling water treatment, and particularly relates to a method and a device for calculating the concentration multiple of circulating cooling water under the condition of water supplementing quality fluctuation.
Background
In the actual industrial production field, the concentration ratio of industrial cooling circulating water and the concentration ratio of a steam boiler are often referred to. For an industrial cooling circulation water system, increasing the concentration ratio has important significance on the system, which is mainly embodied as 'water resource saving', but for a cooling circulation system, the concentration ratio cannot be increased infinitely.
GB/T50050-2017 design Specification for treating industrial circulating cooling water 2.1.15, the definition of the concentration multiple is as follows: the ratio of the salt content of the recirculated cooling water to the make-up water. The concentration times specified in section 3.1.11 of GB/T50050-2017 design Specification for treating industrial circulating cooling water can be calculated according to the following formula:
in the formula, N is the concentration multiple, QmFor supplementing water quantity m3/h,QbFor discharging sewage m3/h,QwLoss of water m for blowing3H is used as the reference value. In the calculation method, the amount of water lost by wind blowing cannot be accurately measured on line due to the influence of factors such as wind speed, direction, on-site cooling tower structure and the like, so that the calculation method has no operability in practical application.
The meaning of the concentration multiple in P35 in the second edition of the "industrial water treatment technology" of the weekly province refers to the ratio of the concentration of a substance in the circulating water to the concentration of a substance in the makeup water. The substance generally selected is CL-、SiO2、K+Etc. or total dissolved solids. In the operation management of the circulating cooling water system, a laboratory generally adopts chloride ions to calculate the concentration multiple, and an on-line laboratory generally adopts conductivity to calculate the concentration multiple, and the concentration multiple can be calculated according to a formula on page P35. The calculation method of page P35 can accurately calculate the concentration factor when the quality of the supplemented water is stable. However, when the circulating cooling water actually runs, the water quality of the supplemented water fluctuates, and the fluctuation range of the water quality of the supplemented water of most systems is large, in this case, the above calculation method is not applicable any more.
