Problems solved by technology

[0002] The main problems in the operation of industrial circulating cooling water systems are: (1) system scaling (2) system corrosion (3) microbial slime
[0003] At present, most of the collection, recording and management of water quality data in industrial circulating cooling water systems are manually operated. Due to the complexity of management projects, errors are inevitable, work efficiency is not high, and there are also situations such as lack of monitoring and measuring equipment and instruments.

Embodiment 1

[0041] See figure 1 Prediction method shown in industrial cooling water, which prediction method comprising the steps of:

[0042] Step S1, the filter is capable of characterizing and determining the number of industrial cooling water quality parameter from the parameter core industrial cooling water.

[0043] Circulating water monitoring parameters are divided into several categories: 1) related to the scaling tendency, such as salinity, alkalinity, calcium ion concentration, total hardness, concentration rate, pH and soluble silica and the like; 2) with the corrosive and anion concentration trends related to corrosion, such as conductivity, chloride ions, iron ions, sulfate ions, pH, concentration rate; 3) and the survival and development of microorganisms related microbial and corrosion, such as COD, chlorine, sulfide , ammonia nitrogen, total number of bacteria, suspended solids, turbidity; 4) related to water treatment chemicals, such as water, organic phosphorus stabilizing ...

specific Embodiment approach

[0103] In a specific embodiment, the step 5 comprises:

[0104] When the specific implementation process, may also be implemented to control the dosage and dosage concentrations according to different control parameters, specifically:

[0105] TP can, the quality parameters of the ORP and conductivity, corrosion inhibitor and biocide were adjusted dosing concentration, the conductivity calculated by feedback regulation of concentration and fill water displacement;

[0106] The stability parameters directly reflect further corrosion and scaling tendency of the water quality adjusting the dose of the inhibitor and a dispersant;

[0107] For example, in practice, it may be stably integrated quality parameters such as Ryznar Stability Index (RSI) and other parameters, corrosion and scaling tendency of a direct reflection of the circulating cooling water, adjusting the intensity according to corrosion or fouling of the dosing recipe scale dose of agent and corrosion inhibitor.

[0108]...

Embodiment 2

[0111] See figure 2 A device for processing industrial cooling water shown, preferably the processing means employing the prediction method disclosed in Example 1 is processed. The processing apparatus comprises a series of pipe or equipment monitoring instruments, heat exchangers, cooling towers and the sump, each of the circulating cooling water system can be connected to the water collection tank on the connected instrument and the order of the system is not particularly limited and may be .

[0112] And provided with a water fill the sump and outfall the serial access pipeline further adding means with a drug, the agent addition device is controlled by the control system, said control system further respective monitoring instruments or instrument electrically connected, for obtaining the parameters.

[0113] The control needs understood, the control system software may be executed in the above-described method of Example 1, or the control system implementing the method under t...

Abstract

The invention discloses a prediction method and device for industrial circulating cooling water. The prediction method comprises the following steps: screening and determining a plurality of core parameters capable of representing the water quality of the industrial circulating cooling water from parameters of the industrial circulating cooling water; establishing a water quality change pre-judgment model and / or a water quality early warning model taking the core parameters as independent variables; monitoring and acquiring a core parameter data table of the industrial circulating cooling water in real time by using an online instrument; obtaining the core parameter data table of the industrial circulating cooling water through laboratory water quality testing; and pre-judging or pre-warning the water quality of the industrial circulating cooling water according to the water quality change pre-judging model and / or the water quality pre-warning model and the core parameter data table. When the prediction method is applied to the industrial circulating cooling water system, the treatment efficiency of circulating cooling water is improved, the stability of water quality is ensured, and waste of water resources is avoided.

Description

Technical field [0001] The present application belongs to the technical field of the industrial cooling water circulation, and more particularly to a method and apparatus for prediction of an industrial cooling water circulating. Background technique [0002] The main problems of industrial cooling water system operation are: (1) scaling system (2) corrosion of the system (3) microbial slime. Way to solve these problems mainly in the circulating water system dosing corrosion inhibitors, scale inhibitors and biocide. In actual operation, just by adding the drug it is not enough. As the saying goes "two-thirds by Pharmacy, seven by management," industrial circulating water system to ensure the safe and stable operation, the need for better processing technology and processing equipment. [0003] The current collection, recording and management of water quality data for industrial cooling water system is mostly hand operation, due to the complex project management, error is inevitab...
