Description

Technical Field

[0001] The utility model relates to the technical field of circulating water dynamic control, and more specifically to a circulating water dynamic simulation device which utilizes images to control a concentration process. Background Art

[0002] The circulating cooling water system is an important part of the industrial cooling system. It is widely used in the fields of electricity, chemical industry and steel. It is also an important link in industrial water-saving control. The control of the concentration ratio of circulating water is of great significance to the control of corrosion and scaling of the entire industrial cooling system. It is also an important means of water-saving optimization. In order to ensure the safe and stable operation of the circulating water system and achieve the maximum water-saving effect, it is necessary to conduct a simulation test of the operation of the circulating cooling water system, screen out the suitable reagents and dosages for the circulating water, and determine the optimal control parameters of the circulating water, in order to achieve the purpose of safe, economical and efficient control.

[0003] At present, the method of controlling the concentration rate of the circulating water dynamic simulation test device is to calculate the limit concentration rate, that is, to judge whether the limit concentration rate has been reached and whether the water body has reached the level of easy scaling by checking whether the difference △A between the chloride ion rate and the calcium ion rate is greater than 0.2. However, due to rainfall or dryness in the external environment, the concentration of chloride ions and calcium ions in the replenishment water will change greatly, and the quality of the replenishment water will deviate greatly from that of the water in the circulating water system, which cannot be controlled by the difference △A between the chloride ion rate and the calcium ion rate. In addition, multiple replenishment waters enter the circulating water dynamic simulation test device at the same time, which makes △A impossible to calculate. Therefore, it is impossible to control the concentration rate of the circulating water by calculating the limit concentration rate. Utility Model Content

Of course, other materials can also be selected according to actual needs, which is not limited here. A cooling mechanism is also installed on the upper part of the circulating water tank 9, and the cooling mechanism may include a packing column 3 and a forced fan 4 for cooling the circulating water.

[0021] It should be noted that the above scheme uses the image method to continuously track the number and particle size characteristics of suspended matter in the water body and record the historical curve of the suspended matter characteristics. If the number and particle size of suspended matter increase abnormally during the concentration process, it means that the circulating water limit concentration ratio has been reached. If the concentration continues, a large number of calcium carbonate scaling particles will appear in the water body. Specifically, by controlling the camera component 1, the number and particle size changes of underwater suspended matter are continuously recorded. By continuously tracking and recording, the concentration process of circulating water can be controlled, and the work of collecting circulating water for water quality analysis multiple times during the concentration process can be avoided, saving a lot of manpower. The conventional dynamic test concentration ratio is controlled by sampling and analyzing the chloride ion concentration in the water sample. However, the analysis of chloride ion concentration often has large errors. Tracking the concentration process by the image method instead of chemical analysis can greatly eliminate human errors. The solution of the present application adopts a camera component 1. When it is found that the increase rate of suspended matter in the water body does not match the concentration rate, the discharge volume is controlled to avoid the impact of the lag in the results of the analysis process on the scaling of the system. The concentration rate is controlled by collecting images, which provides a better solution for multiple water sources or scenarios with large fluctuations in water quality in actual operation.

[0022] It can be seen from the above technical scheme that in the embodiment of the circulating water dynamic simulation device for controlling the concentration process by using images provided by the utility model, since it includes a circulating water tank, a camera component is arranged in the circulating water tank, the camera component is in communication connection with the control component, the control component is used to control the camera component to take pictures and perform two-dimensional image recognition, analysis, calculation and classification on the photographed particles, judge whether the suspended matter in the water body has increased significantly, and judge whether the concentration end point has been reached according to the suspended matter situation. The circulating water tank is also connected to the circulation drive component, the pipeline switch component, the pipeline flow measurement component, the imported corrosion hanging piece test barrel, the imported The simulated heat exchange chamber is provided with a simulated heat exchange tube, and the simulated heat exchange tube is connected to the simulated steam cooling component and the simulated steam generating component in sequence. The simulated steam generating component is also connected to the heating component. A cooling mechanism is also installed on the upper part of the circulating water tank. Therefore, it can effectively reduce the manual timing and fixed-point testing work in the operation of the circulating water system, avoid the lag of water quality testing, and effectively solve the problem of lack of control method caused by water quality fluctuations and water source changes, so as to realize controllable concentration process and effectively prevent scaling.

[0023] In a specific embodiment of the circulating water dynamic simulation device for controlling the concentration process using images, the camera component 1 can preferably be arranged at a stable water flow position in the circulating water tank 9, so that it will not be impacted by the water flow, thereby better ensuring its own safety, and the outside is wrapped with a stainless steel metal shell with a waterproof grade of not less than IP68, so that water will not enter the interior, thereby better avoiding malfunctions. The lens part of the camera component 1 is explosion-proof glass and is provided with a self-cleaning brush for cleaning the lens, so that the service life of the camera component 1 is longer and it is not easy to be damaged, and the self-cleaning brush can ensure that the lens is always kept clean, and no misjudgment will occur, thereby better ensuring the accuracy of concentration control.

[0024] The operation process of the above device is as follows: the circulation drive component 5 starts to operate, the heating component 16 starts to heat, the steam gradually enters the simulated heat exchange tube 13, starts to exchange heat with the circulating water, the circulating water system starts to gradually concentrate, the heat of the circulating water is taken out of the system by the forced fan 4, the circulating water in the circulating water tank 9 gradually concentrates, and the suspended solids in the water body also increase, which is proportional to the concentration ratio. The camera component 1 records the number of suspended solids in the water body, the particle size and other parameters.
