The dynamic simulation test performed in the laboratory is a necessary step for scale and corrosion inhibition treatment of the circulating cooling water, and is an experimental method closer to the actual operation condition. The dynamic simulation device for the circulating cooling water is an important device for researching the treatment of the circulating cooling water.

Further, the medicine replenishing pipe 23 is connected to a medicine storage box 26 via a peristaltic pump 25. The medicine box 26 stores the prepared medicines. Because the alkalinity of water quality in some places is higher, a medicament needs to be added into cooling water for neutralization, and the scaling phenomenon inside the heat exchanger is avoided.
According to the main ion Ca in water2+、HCO3 -Accurately and continuously replenishes the ion components lost in the water, and keeps the ion concentration in the circulating cooling water unchanged. Namely: ion replenishment rate is an ion loss rate.
Generally, before the actual test, a main ion loss rate measurement test is first performed to measure Ca in the circulating cooling water2+、HCO3 -Loss rate of ions, converted into analytically pure CaCl2And NaHCO3The dosage concentration is controlled by a peristaltic pump 25 according to the loss rate.
Specifically, the flow control range of the peristaltic pump 25 is 0.002-380mL/min, and the precision is 0.002 mL/min.
Through adopting above-mentioned technical scheme, in whole experimentation, along with the development of time, the distilled water is taken away in the continuous evaporation of system's heat transfer, and remaining water source quality of water is constantly concentrated, and the control switch on storage water tank bottom blow off pipe 201 opens when quality of water conductance reaches the settlement limit value, begins the drainage, and the control switch on the upper portion moisturizing pipe 202 is opened, begins to supply fresh water source, dilutes concentrated quality of water to the concentration of neutralization ion maintains in certain concentration range, improves the precision of simulation experiment result. Also, the peristaltic pump 25 operates to replenish the lost amount of medicament. When the conductivity of the water quality reaches the set bottom limit, the control switch on the sewage discharge pipe 201 is closed, the control switch on the water replenishing pipe 202 is closed, the peristaltic pump 25 stops working, and the adding of the medicament is stopped.
According to the loss rate of ions in water in the test operation process, the lost ion components in the water are accurately and continuously supplemented, the ion concentration in the circulating cooling water is kept constant, and the working condition of the circulating cooling water is similar to that of the circulating cooling water actually operated in industry. Thus, the circulating cooling water is no longer a closed system, and can be considered an open system.
The whole device can be controlled by a control system and a computer. The control system can be connected in a control cabinet 27, the control cabinet 27 is arranged on the site of the circulating cooling water simulation device, the liquid level detecting meters, the pH on-line instrument 16, the electric conduction on-line instrument 17, the rotor flow meter 20, the inlet temperature on-line instrument 18, the outlet temperature on-line instrument 19 and the steam temperature on-line instrument 24 measure data, the inlet temperature, the outlet temperature and the steam temperature data of the tubular heat exchanger 12 are monitored, the inlet pH value, the electric conductivity and the liquid level detecting meters display the data, and the data are transmitted to a computer.
