Description

Technical Field

[0001] The present application relates to the field of measurement technology, and in particular to a method, device, equipment and medium for measuring the drift rate of a cooling tower. Background Art

[0002] The cooling tower is a common device in the industrial and civil fields. It reduces the temperature of water by exchanging heat between water and air. When the water is cooled in the cooling tower, a small part of the water will evaporate or be blown away due to the flow of air. This phenomenon is called "water drift". The water drift rate refers to the ratio between the amount of water lost due to air flow and the total amount of water entering the cooling tower within a specific period of time.

[0003] In the related art, in order to determine the water drift rate of a cooling tower, filter paper is usually placed at the outlet of the cooling tower for a period of time (about 1 minute to 5 minutes) to collect the water lost due to air flow. Subsequently, the total water drift amount is calculated based on the mass difference between the filter paper after moisture absorption and the dry filter paper, combined with factors such as the filter paper area and collection time, and can be compared with the total water entering the cooling tower to obtain the water drift rate of the cooling tower.

[0004] However, this method requires the use of a high-precision balance (sensitivity up to 0.001g) to measure the mass of the filter paper after moisture absorption and the dry filter paper, and also requires physical and chemical laboratory-level drying equipment to determine the absolute dryness of the filter paper. This not only increases the experimental cost, but also increases the difficulty in actual operation. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0053] As described above, in order to determine the water drift rate of a cooling tower, filter paper is usually placed at the outlet of the cooling tower for a period of time (about 1 minute to 5 minutes) to collect the water lost due to air flow. Subsequently, the total amount of water drift is calculated based on the mass difference between the filter paper after moisture absorption and the dry filter paper, combined with factors such as the filter paper area and collection time, and can be compared with the total amount of water entering the cooling tower to obtain the water drift rate of the cooling tower.

[0054] However, this method requires the use of a high-precision balance (sensitivity up to 0.001g) to measure the mass of the filter paper after moisture absorption and the dry filter paper, and also requires physical and chemical laboratory-level drying equipment to determine the absolute dryness of the filter paper. This not only increases the experimental cost, but also increases the difficulty in actual operation.

[0055] After research, the inventor proposed a method, device, equipment and medium for determining the drift rate of a cooling tower. The method includes: determining the initial mass of a water-absorbing vessel and the cooling water flow rate of the cooling tower, the water-absorbing vessel is located in the water tank of the cooling tower and is higher than the liquid level of the water tank; when the operation time of the cooling tower reaches the preset operation time, determining the water absorption mass of the water-absorbing vessel; determining the splash rate of the cooling tower according to the initial mass, the water absorption mass, the cooling water flow rate and the surface area of ​​the water tank; determining the drift rate of the cooling tower according to the splash rate of the cooling tower and the preset relationship curve. Therefore, the method for determining the drift rate of the cooling tower no longer needs to use a high-precision balance and a drying device at the level of a physical and chemical laboratory, and can use an ordinary weighing device to complete the mass measurement of the water-absorbing vessel, which greatly reduces the experimental cost and reduces the difficulty in actual operation, making on-site determination more feasible.

[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] See also Figure 1 , which is a flow chart of a method for determining the drift rate of a cooling tower provided in an embodiment of the present application. The method comprises:

[0058] S101: Determine the initial mass of the water absorption vessel and the cooling water flow rate of the cooling tower, the water absorption vessel is located in the water tank of the cooling tower and is higher than the water level of the water tank.

[0059] When the cooling tower is not in operation, you first need to prepare a water absorption vessel. The water absorption vessel is usually a square vessel of 200mm (millimeter) x200mmx100mm, and a water-absorbing material (such as a sponge) is placed inside. In addition, it is necessary to ensure that the water absorption vessel is located in the water tank of the cooling tower and is higher than the water level of the water tank. The purpose of this is to avoid the water absorption vessel directly contacting the accumulated water in the water tank, thereby ensuring that the measured mass change comes only from the splashed water. Subsequently, the original mass (i.e., initial mass) of the water absorption vessel is accurately measured using a weighing device and recorded.

[0060] In some specific implementations, in order to ensure the accuracy of the measurement, 9 water absorption vessels can be set. Figure 2 , which is a schematic diagram of a cooling tower provided in an embodiment of the present application. Figure 2 It can be seen that the 9 water-absorbing vessels can be evenly placed at different positions in the cooling tower water tank (in the red box) to ensure that the possible splashing area can be fully covered. When determining the initial mass of the water-absorbing vessel, the sum of the initial masses of the 9 water-absorbing vessels can be obtained. It should be noted that this application does not limit the number of water-absorbing vessels.

[0061] When the cooling tower is not in operation, it is also necessary to record the cooling water flow rate Q (unit: m 3 / h). Recording the cooling water flow rate is essential for the subsequent calculation of the splash rate, which is based on the ratio between the amount of water entering the cooling tower and the amount of water splashing into the tank per unit time.

[0062] S102: When the operation time of the cooling tower reaches a preset operation time, the water absorption quality of the water absorption vessel is determined.

[0063] After the preparation work of step S101 is completed, the cooling tower is started and the timing is started. When the cooling tower is running, it is necessary to ensure that the cooling tower operates according to normal working conditions and all parameters (such as cooling water flow, wind speed, etc.) are in a stable state.

[0064] The preset operation time refers to the length of time the cooling tower needs to run continuously. This time is usually determined based on the test purpose and actual working conditions. Since a time that is too short may result in insufficient data, and a time that is too long may increase unnecessary operational complexity, the preset operation time is generally selected between 10 minutes and 60 minutes to ensure that there is enough data collection time to accurately reflect the actual working status of the cooling tower.

[0065] When the timing result indicates that the cooling tower has reached the preset operation time, the cooling tower is stopped immediately. Then, the water absorption container is quickly taken out (the purpose is to reduce the mass change caused by factors such as evaporation), and the mass of the water absorption container is weighed using a weighing device to determine the water absorption mass.

[0066] It should be noted that, if nine water absorbing vessels are provided, then in step S102 , the sum of the water absorbing masses of the nine water absorbing vessels needs to be determined.

[0067] S103: Determine the splash rate of the cooling tower based on the initial mass, water absorption mass, cooling water flow rate and the surface area of ​​the water tank.

[0068] First, for the water absorption vessel, subtract the initial mass from its absorbed mass to obtain the net mass increase M of the water absorption vessel. Then, measure the surface area S (unit: m) of the water tank between the fillers on both sides of the cooling tower. 2 ).like Figure 2 It can be seen that the surface area S of the water tank is Figure 2 The orange area in the figure. This step is to determine the effective receiving area of ​​the water tank so that the splashing amount per unit area can be calculated. Subsequently, the splashing rate of the cooling tower is determined based on the net mass increase, the cooling water flow rate and the surface area of ​​the water tank. The splashing rate δ represents the proportion of water splashing into the water tank in the cooling tower to the total water entering the cooling tower per unit time. The higher the splashing rate δ, the greater the water loss inside the cooling tower and the higher the possibility of drifting water.

[0069] In some specific implementations, the determination formula of the splash rate δ of the cooling tower is specifically shown in the following formula (1):

[0070]

[0071] Among them, δ is the splash rate of the cooling tower, M is the mass difference between the absorbed mass and the initial mass (i.e., the net increase in mass), S is the surface area of ​​the water tank, T is the operating time of the cooling tower, and Q is the cooling water flow rate.

[0072] It should be noted that if 9 water absorbing vessels are provided, the splash rate of the cooling tower needs to be determined in step S103 according to the average value of the net added mass of the 9 water absorbing vessels, the cooling water flow rate and the surface area of ​​the water tank. The average value of the net added mass of the multiple water absorbing vessels is the ratio of the first value to the number of the water absorbing vessels, and the first value is the difference between the sum of the water absorbed mass of the multiple water absorbing vessels and the sum of the initial mass of the multiple water absorbing vessels.

[0073] S104: Determine the water drift rate of the cooling tower according to the splash rate of the cooling tower and a preset relationship curve.

[0074] It can be understood that the splash rate refers to the ratio of the amount of water splashed into the water tank in the cooling tower to the total amount of water entering the cooling tower, and the drift rate refers to the ratio of the amount of water flying out of the cooling tower to the total amount of water entering the cooling tower. Through experiments, it was found that there is a certain functional relationship (i.e., a preset relationship curve) between the splash rate and the drift rate. This is because most of the splashed water will eventually remain in the water tank, while a small part will fly out of the tower to form drift water. Once the preset relationship curve is established, the preset relationship curve can be used to deduce the drift rate under actual working conditions.

[0075] In some specific implementations, the preset relationship curve is determined as follows:

[0076] First, select a suitable water-absorbing vessel and place it inside the water tank of the cooling tower, and set filter paper outside. Record their respective initial sample masses. Also, determine the cooling water flow rate value of the cooling tower sample used in the experiment (i.e., the sample cooling water flow rate of the cooling tower).

[0077] Next, let the cooling tower run for a preset operating time according to the set parameters, and immediately measure the water absorption mass of the water absorption container and filter paper samples after stopping.

[0078] Subsequently, the sample splash rate of the cooling tower is determined using the sample initial mass of the water absorption vessel, the sample water absorption mass of the water absorption vessel, the sample cooling water flow rate, and the surface area of ​​the water tank. The calculation formula is the same as formula (1) and is not repeated here. In addition, the sample drift rate of the cooling tower is determined using the sample initial mass of the filter paper, the sample water absorption mass of the filter paper, and the area of ​​the filter paper.

[0079] Finally, multiple sets of data points of sample splashing rate and sample drifting rate are obtained through repeated experiments, and these data points are fitted using statistical methods (such as least squares method, etc.) to form a best matching line or curve, that is, the preset relationship curve.

[0080] In summary, the embodiment of the present application provides a method for determining the drift rate of a cooling tower, the method comprising: determining the initial mass of a water-absorbing vessel and the cooling water flow rate of the cooling tower, the water-absorbing vessel being located in a water tank of the cooling tower and being higher than the liquid level of the water tank; when the operation time of the cooling tower reaches a preset operation time, determining the water absorption mass of the water-absorbing vessel; determining the splash rate of the cooling tower according to the initial mass, the water absorption mass, the cooling water flow rate and the surface area of ​​the water tank; determining the drift rate of the cooling tower according to the splash rate of the cooling tower and a preset relationship curve. Thus, the method for determining the drift rate of the cooling tower no longer requires the use of a high-precision balance and a drying device at the level of a physical and chemical laboratory, and can use an ordinary weighing device to complete the mass measurement of the water-absorbing vessel, which greatly reduces the experimental cost and reduces the difficulty in actual operation, making on-site determination more feasible.
