Description

Technical Field

[0001] This utility model belongs to the field of circulating water testing technology, specifically relating to a circulating water corrosion rate detection device. Background Technology

[0002] Corrosion in circulating water refers to the damage to metal equipment in water caused by electrochemical processes, dissolved oxygen, pH levels, and salts, and is commonly seen in production. Corrosion can lead to pitting and perforation on equipment surfaces, and in severe cases, it can even render equipment unusable. Corrosion reduces the heat transfer efficiency of equipment, resulting in higher energy consumption under the same production conditions. Furthermore, metal ions generated by corrosion may be discharged into the environment with the circulating water, causing pollution. Therefore, monitoring the rate of corrosion in circulating water during production can significantly reduce production costs.

[0003] Currently used circulating water corrosion rate detection devices have relatively simple detection methods and low efficiency. When applied to large-scale production processes, the data deviation is large and cannot accurately reflect the corrosion status and corrosion rate of different equipment. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a circulating water corrosion rate detection device to realize the detection of the corrosion rate of circulating water under different environments and improve production control efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: The circulating water corrosion rate detection device of this utility model includes a circulating water tank, an inlet pipe connected to the top of the circulating water tank, a sedimentation tank connected to the circulating water tank, a flow meter installed between the circulating water tank and the sedimentation tank, several baffles installed inside the sedimentation tank, a vacuum pump connected to the sedimentation tank, a circulating water tower connected to the vacuum pump, a buffer tank connected to the circulating water tank, and several buffer pipes installed inside the buffer tank; the baffles, buffer pipes, the inner wall of the circulating water tower, and the flow meter are all electrically connected to detectors.

[0006] The bottom of the circulating water tank is connected to the top of the sedimentation tank, the bottom of the sedimentation tank is connected to the vacuum pump, and the vacuum pump is connected to the upper part of the circulating water tower.

[0007] The water inlet pipe is equipped with a liquid inlet valve.

[0008] The top of the circulating water tank is equipped with an alkaline solution pipe and an acid solution pipe, and the bottom of the circulating water tank is connected to a drainage pipe.

[0009] The aforementioned baffles are staggered and spaced at the top and bottom of the sedimentation tank, and the baffles are connected to each other by connecting plates.

[0010] The detector includes a receiving end and a transmitting end. The flow baffle, buffer pipe, and inner wall of the circulating water tower are all connected to the receiving end, and the transmitting end is connected to the flow meter.

[0011] The detector's receiver has a sensing component inside.

[0012] A control valve is installed between the circulating water tank and the sedimentation tank, and the flow meter is electrically connected to the control valve.

[0013] The buffer tank is connected to the inlet pipe via a pipeline at the end furthest from the circulating water tower.

[0014] The sedimentation tank is equipped with a jacket on the outside, with an inlet at the bottom and an outlet at the top.

[0015] The beneficial effects of this utility model are: This invention adjusts the temperature, pH, and flow rate of circulating water before circulating it through sedimentation tanks, circulating water towers, and buffer tanks of different structures. The corrosion rate of the circulating water on these three tanks is observed. In the sedimentation tank, a baffle plate slows the water flow and allows it to remain submerged in the circulating water for an extended period. The baffle plate is connected to a sensor in a detector; changes in current generated on the surface of the corroded baffle plate are transmitted to the detector, enabling timely detection of corrosion locations and allowing for observation of the degree of corrosion based on the magnitude of the current change. In the circulating water tower, the circulating water enters through an upper flushing mechanism. By detecting and collecting signals from the inner wall of the circulating water tower, the scouring effect of the circulating water on the inner wall can be quickly observed. The buffer pipes in the buffer tank are similar in structure and material to the existing pipelines, allowing feedback on the corrosion of the pipelines by the circulating water. When corrosion is detected, the pH, temperature, and flow rate of the circulating water are adjusted to obtain the change in corrosion rate. This facilitates adjustments to the production process based on data during subsequent production, significantly reducing maintenance costs during production. Attached Figure Description

[0017] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] Example 1 like Figure 1-2 As shown, the circulating water corrosion rate detection device includes a circulating water tank 1, an inlet pipe 8 connected to the top of the circulating water tank 1, a sedimentation tank 2 connected to the circulating water tank 1, a flow meter 7 installed between the circulating water tank 1 and the sedimentation tank 2, several baffles 201 installed inside the sedimentation tank 2, a vacuum pump 3 connected to the sedimentation tank 2, a circulating water tower 4 connected to the vacuum pump 3, a buffer tank 5 connected to the circulating water tank 1, and several buffer pipes 501 installed inside the buffer tank 5; detectors 6 are electrically connected to the baffles 201, the buffer pipes 501, the inner wall of the circulating water tower 4, and the flow meter 7.

[0019] The bottom of the circulating water tank 1 is connected to the top of the sedimentation tank 2, the bottom of the sedimentation tank 2 is connected to the vacuum pump 3, and the vacuum pump 3 is connected to the upper part of the circulating water tower 4.

[0020] An inlet valve 801 is installed on the inlet pipe 8.

[0021] The top of the circulating water tank 1 is equipped with an alkaline solution pipe 9 and an acid solution pipe 10, and the bottom of the circulating water tank 1 is connected to a drain pipe 101.

[0022] Several baffles 201 are staggered and spaced at the top and bottom of the sedimentation tank 2, and the baffles 201 are connected by connecting plates.

[0023] The detector 6 includes a receiving end 601 and a transmitting end 602. The flow baffle 201, the buffer pipe 501, and the inner wall of the circulating water tower 4 are all connected to the receiving end 601, and the transmitting end 602 is connected to the flow meter 7.

[0024] The receiver 601 of detector 6 has a sensing component inside.

[0025] A control valve is installed between the circulating water tank 1 and the sedimentation tank 2, and the flow meter 7 is electrically connected to the control valve.

[0026] The buffer tank 5 is connected to the inlet pipe 8 via a pipeline at one end away from the circulating water tower 4.

[0027] The sedimentation tank 2 is provided with a jacket 202 on the outside, with an inlet at the bottom and an outlet at the top.

[0028] Working principle and process: Circulating water is added to circulating water tank 1, and then the pH value of the circulating water is adjusted through alkaline solution pipe 9 and acid solution pipe 10. It then enters sedimentation tank 2. The baffle plate 201 inside sedimentation tank 2 generates a corresponding electrical signal after being impacted by the circulating water, which is transmitted to the sensing component inside the receiver 601 of detector 6. The data is then transmitted to the transmission end 602. Continuous observation of the data fluctuation frequency of detector 6 allows for a direct observation of the corrosion rate of the baffle plate 201 by the circulating water. The circulating water then enters the circulating water tower 4 to flush it. The receiver 601 collects the electrical signals on the inner wall of the circulating water tower 4 and transmits them to detector 6, obtaining corrosion data of the circulating water on the circulating water tower 4. The circulating water is then... The circulating water is then fed into buffer tank 5 and flows slowly through buffer pipe 501. Receiver 601 collects the current signal generated on buffer pipe 501 and displays it in detector 6. The data in detector 6 is transmitted to flow meter 7, which adjusts the opening of control valve. By changing the pH, temperature, and flow rate of the circulating water and circulating it multiple times, the time of corrosion occurrence and the rate of change in the degree of corrosion can be obtained. Then, the circulating water is discharged from drain pipe 101, and new circulating water is added from inlet valve 801. The conditions of the circulating water are changed and the test is repeated. During the production process, the production equipment is maintained according to the corrosion rate of the circulating water, which greatly improves production efficiency.
