The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example 1
In a water system in the prior art, for example, a water supply system, a circulating water system, a drainage system, a wastewater discharge system, a water treatment system and the like, a pipe network structure is often complex, and data detection points are arranged in a mess, so that the salt content change of each water unit in the water system is difficult to measure and count accurately in real time. Meanwhile, the traditional salt balance monitoring process usually adopts manual calculation, the number of measuring points according to calculation is small, the counting time is short, and the salt amount in water cannot be accurately reflected on line in real time.
In order to solve the problems that the pipe network structure is complex, the data detection points are arranged in a mess, and the change of the salt content of each water unit in the water system is difficult to measure and count accurately in real time in the prior art, the salt balance monitoring device for the water system is provided in the embodiment, as shown in the attached drawing 1-2, the salt balance monitoring device for the water system comprises a pipeline unit, and the pipeline unit comprises an upstream pipeline 1, a water unit 2 and a downstream pipeline 3 which are connected in sequence along the flowing direction of a water body, wherein the water unit 2 comprises at least one of a water using device, a water treating device and a dosing device 21 and is used for supplying water, treating water or dosing operation meeting the industrial production or process requirements. The upstream pipeline 1 is provided with a first detection unit 11, the downstream pipeline 3 is provided with a second detection unit 31, and the first detection unit 11 and the second detection unit 31 can detect the flow and the conductivity of the water body in real time.

Meanwhile, the method is also beneficial to simplifying the pipe network structure, ensuring the detection, the check and the verification of the salt content in the corresponding pipeline or water unit, timely discovering data errors in the detection process, ensuring the consistency of the data and timely discovering possible faults of the corresponding detection unit. In addition, the salt content conditions of related pipelines and water units are detected and counted by the salt balance monitoring device, so that effective management and control of a water system of a whole plant are facilitated, and water conservation, emission reduction, environmental protection and water pollution prevention are facilitated.
TDS = flow (m) for a line for calculation of the salt content (TDS in english) in the respective line 3 (ii)/h) x conductivity (μ S/cm) x K x 1000; wherein the K value is a salt coefficient. So that the salt content of the water body flowing into a certain pipeline in a certain time can be determined through manual calculation or computer processing. Furthermore, the change of the salt content of each water unit in the water system can also be determined by the change of the TDS of the upstream pipeline 1 and the TDS of the downstream pipeline 3. Correspondingly, if the adjustment condition of the TDS in the water unit 2, such as the dosage, the salt precipitation amount, etc., is determined, the detection results of the upstream pipeline 1 and the downstream pipeline 3 can also be checked and verified to ensure the consistency of the upstream and downstream data based on the material conservation or the salt balance.

| Water source kind | Conductivity Range (μ S/cm) | K |
| Fresh water | 0-300 | 0.50 |
| Ordinary water | 301-4000 | 0.55 |
| Brackish water | 4001-20000 | 0.67 |
| Seawater, its production and use | 20001-6000 | 0.70 |

The dose amount of the drug adding device 21 can be determined by calculation such as manual calculation or computer processing according to the calculation formula of the dose amount = drug concentration × drug flow rate. Meanwhile, by using a calculation formula of TDS = flow rate × conductivity × K, on the basis of calculating the TDS of the upstream pipeline 1 and the TDS of the downstream pipeline 3, each data can be checked.

In addition to cases 1-3, at least any two of the water using device, the water treatment device, and the drug adding device 21 may be arranged in series and/or in parallel, for example: the water using device and the water treatment device are connected in parallel, share one upstream pipeline 1 and one downstream pipeline 3, and are respectively regarded as an upstream main pipe and a downstream main pipe.
