Description

Technical Field

[0001] The invention relates to the technical field of transformer production and manufacturing, and in particular to a device for measuring water output of kerosene gas phase drying equipment and a method for measuring water output by using the device. Background Art

[0002] Kerosene vapor phase drying equipment is a relatively advanced special technical equipment currently used in the transformer industry for drying transformer bodies and coils. In the process of using kerosene vapor phase drying equipment to dry power transformers, the water output of the drying transformer will be monitored throughout the process, and the drying procedure will be further adjusted according to the water output. Therefore, the higher the requirements for water output and water output accuracy, the better.

[0003] The prior art (such as CN211696606U) usually adopts similar Figure 4 The water output measuring device of the kerosene vapor phase drying equipment shown in the figure is used to count the water output. The water and kerosene in the production process are sucked into the collection tank by the vacuum degree in the collection tank for water-oil separation, and the water is stored in the liquid storage barrel at the bottom of the collection tank and the water level meter is used to measure the water. Due to the manufacturing precision, the water level meter cannot measure the liquid level very accurately. In addition, the measurement area of ​​the liquid storage barrel in the collection tank is relatively large, and each 10mm corresponds to 1.2L, or even a larger value, which is easy to cause errors. In addition, the liquid storage barrel of the collection tank needs to be drained by a pump under vacuum, resulting in large fluctuations in the liquid level, further causing errors, and causing inaccurate water output and water output calculation. This situation has a serious impact on the subsequent drying product process: it makes the drying time longer, the production efficiency is low, the equipment loss is increased, and the telephone bill loss is also large. Therefore, in view of the large deviation between the quality control drying record and the theoretical water output in the existing kerosene vapor phase drying equipment, a kerosene vapor phase drying equipment with high water output metering accuracy is invented. Summary of the invention

[0004] The purpose of the present invention is to solve the technical deficiencies and provide a kerosene gas phase drying device with high water output metering accuracy. The device has a simple structure, is easy to operate, reduces production costs, and has the functions of automatic measurement and fault monitoring. The present invention also provides a method for measuring the water output using the device. The method is simple to operate and has a small water output measurement error.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] A device for measuring water output of kerosene gas phase drying equipment comprises a collecting tank for absorbing and collecting a mixed liquid of water and kerosene, the collecting tank having a certain degree of vacuum, a quantitative tank for storing water separated from the collecting tank being provided at the bottom of the collecting tank, a flow control structure being connected to a pipeline between the quantitative tank and the collecting tank, a water level detector being connected to the quantitative tank for detecting whether the quantitative tank is full of water, the installation height of the water level detector being not lower than the installation height of the flow control structure, a drainage structure being provided below the quantitative tank, and a balancing valve for balancing the air pressure in the quantitative tank and the collecting tank being connected to a pipeline between the quantitative tank and the collecting tank.

[0007] In the above-mentioned device for measuring water outlet of kerosene gas phase drying equipment, the water level detector pipeline is connected between the flow control structure and the collection tank.

[0008] In the above-mentioned device for measuring water outlet of kerosene gas phase drying equipment, the water level detector is an audible and visual water level alarm.

[0009] In the above-mentioned kerosene gas phase drying equipment water outlet measuring device, the installation height of the balancing valve should not be higher than the installation height of the water level detector.

[0010] The kerosene gas phase drying equipment water outlet measuring device as described above also includes a control system, the water level detector and the balance valve are electrically connected to the control system respectively, and when the water level detector detects that the quantitative tank is full of water, the control system controls the balance valve to close.

[0011] In the above-mentioned kerosene gas phase drying equipment water outlet measuring device, the flow control structure and the drainage structure are electrically connected to the control system respectively.

[0012] In the above-mentioned kerosene gas phase drying equipment water outlet measuring device, the collecting tank is provided with a vacuum extraction structure, and the vacuum degree of the collecting tank is 42-48 mbar.

[0013] In the above-mentioned device for measuring water outlet of kerosene gas phase drying equipment, the collecting tank is provided with a kerosene level detector and an oil discharge mechanism for discharging kerosene.

[0014] The present invention also provides a method for measuring the water output of the above-mentioned kerosene gas phase drying equipment water output measuring device, which specifically comprises the following steps:

[0015] S1. Close the flow control structure and the balancing valve and open the drainage structure under the quantitative tank to ensure that the water in the flow control structure, the pipeline under the balancing valve and the quantitative tank is completely drained;

[0016] S2. Close the drainage structure, open the balancing valve, and after the air pressure in the metering tank and the collection tank is balanced, open the flow control structure to introduce the water at the bottom of the collection tank into the metering tank;

[0017] S3. After the water level detector detects that the quantitative tank is full of water, close the balancing valve and the flow control structure, and then open the drainage structure under the quantitative tank to drain the water. When the water in the flow control structure, the pipeline under the balancing valve, and the water in the quantitative tank are completely drained, record the drainage once and the amount of water discharged;

[0018] S4. Repeat the steps in S2 and S3, and record the number of drainages within a certain period of time, and calculate the hourly water output of the kerosene vapor drying equipment based on the number of drainages and the amount of water discharged each time.

[0019] Furthermore, the method for measuring water output by the water output measuring device of the kerosene vapor phase drying equipment of the present invention also includes drainage fault detection, and the drainage fault detection includes excessive drainage fault caused by failure of the flow control structure and the drainage structure and low water output fault caused by abnormality of the vapor phase drying equipment.

[0020] During the process of the gas phase drying device of the present invention, the vacuum extraction structure on the collection tank is always open, so that the vacuum degree of the collection tank is maintained at 42-48 mbar. The water and kerosene mixed liquid condensed by the gas phase drying device enters the collection tank through the condensate collection valve. Since the density of water is 1000 kg / m 3 , the density of kerosene is about 800kg / m 3 , the density of water is greater than that of kerosene. According to the principles of physics, stratification is formed, kerosene will float to the upper part of the collection tank, and water will sink to the bottom of the collection tank. At this time, the flow control structure between the quantitative tank and the collection tank is opened, the balancing valve is opened, and the drainage structure under the quantitative tank is closed. The water at the bottom of the collection tank will enter the quantitative tank to complete the water collection. After the water level detector detects that the quantitative tank is full of water, the balancing valve and the flow control structure are closed, and then the drainage structure under the quantitative tank is opened for drainage. The water in the pipeline under the flow control structure and the balancing valve and the water in the quantitative tank are completely drained by gravity, and the drainage is recorded once; in the process of collecting water, more and more kerosene will appear in the upper layer of the collection tank, and the kerosene level detector detects the upper limit kerosene level of the collection tank, opens the oil discharge mechanism to discharge the kerosene, and when the kerosene level detector detects the lower limit kerosene level of the collection tank, closes the oil discharge mechanism and stops discharging the kerosene; the above process is repeated during production.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The water outlet measuring device of the kerosene gas phase drying equipment of the present invention has a simple structure, high water outlet metering accuracy, convenient operation, and reduced production cost;

[0023] 2. The water in the quantitative tank of the water outlet measuring device of the kerosene gas phase drying equipment of the present invention can be directly discharged by gravity, thereby avoiding the level measurement fluctuation caused by the water level gauge when the water is drained by the drainage pump, resulting in the water outlet metering error;

[0024] 3. The present invention provides a control system on the water outlet measuring device of the kerosene gas phase drying equipment, and the water level detector, the balance valve, the flow control structure, and the drainage structure are electrically connected to the control system respectively. The water inlet and drainage of the quantitative tank can be controlled by the control system, and the drainage times and drainage volume can be recorded, with high automation.

[0025] 4. The method for measuring water output by using the device of the present invention is simple to operate, has a small error in water output measurement, and also performs drainage fault detection, further ensuring the accuracy of water output measurement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below with reference to specific embodiments.

[0033] The following specific embodiments illustrate the implementation of the present invention, and the described embodiments are partial embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1 As shown, a water outlet measuring device of a kerosene gas phase drying device in an embodiment of the present invention comprises a collecting tank 1 for absorbing and collecting a mixed liquid of water and kerosene, the collecting tank 1 has a certain vacuum degree, a quantitative tank 2 for storing the water separated from the collecting tank 1 is provided at the bottom of the collecting tank 1, a flow control structure 3 is connected to the pipeline between the quantitative tank 2 and the collecting tank 1, a water level detector 4 for detecting whether the quantitative tank 2 is full of water is connected to the quantitative tank 2, and the installation height of the water level detector 4 should not be lower than the installation height of the flow control structure 3, a drainage structure 5 is provided below the quantitative tank 2, and a balancing valve 6 for balancing the air pressure in the quantitative tank 2 and the collecting tank 1 is connected to the pipeline between the quantitative tank 2 and the collecting tank 1. In the present invention, the flow control structure 3 is installed on the pipeline between the quantitative tank 2 and the collecting tank 1, and the two ends of the pipeline are respectively located at the bottom of the collecting tank 1 and the top of the quantitative tank 2. The installation height generally refers to the vertical distance between the corresponding device or structure and the horizontal plane, and the installation height of the water level detector 4 generally refers to the vertical distance between the liquid measuring end surface of the water level detector 4 and the horizontal plane.

[0036] In the present invention, a pipe 61 for installing a balancing valve 6 for air circulation is provided between the quantitative tank 2 and the collection tank 1. Both ends of the pipe 61 are respectively installed on the top of the quantitative tank 2 and the collection tank 1. In this way, when the drainage structure 5 is closed and the balancing valve 6 is opened, the atmospheric pressure in the quantitative tank 2 can be slowly circulated to the collection tank 1, so that the collection tank 1 and the quantitative tank 2 reach a gas balance, and the excess water upstream of the balancing valve 6 in the pipe 61 can be returned to the collection tank 1, and flow into the top of the collection tank 1 to re-separate the oil and water. In the production process, a balancing valve 7 with a smaller diameter (usually DN15) is generally used to allow the gas in the quantitative tank 2 to slowly enter the collection tank 1, so that no obvious gas shock will be generated to the collection tank 1.

[0037] The kerosene gas phase drying equipment water outlet measuring device of the present invention has a simple structure, high water outlet metering accuracy, convenient operation, and reduced production cost. The present invention provides a certain volume tank 2 below the collecting tank 1. When the water level detector 4 detects that the quantitative tank 2 is full of water, the flow control structure 3 and the balance valve 6 can be manually closed, and the drainage structure 5 below the quantitative tank 2 can be opened. The water in the quantitative tank 2 can be directly discharged by gravity, avoiding the measurement error caused by the liquid level fluctuation in the liquid storage barrel 12 caused by the detection water level meter 13 when the drainage pump 52 is used for drainage, and saving the cost of using the drainage pump 52 to extract water from the liquid storage barrel 12; in order to speed up the drainage speed of the water in the quantitative tank 2, the aperture of the drainage structure 5 should be as large as possible. The installation height of the liquid measuring end face of the water level detector 4 of the present invention should not be lower than the installation height of the flow control structure 3. This ensures that when the flow control structure 3 and the balancing valve 6 are closed, the moisture in the part of the pipeline connecting the flow control structure 3 and the quantitative tank 2 and the moisture in the quantitative tank 2 are quantitative each time and basically do not fluctuate. Compared with the prior art, the water output metering accuracy is high.

[0038] In order to facilitate the counting of the water output, a quantitative tank 2 with a volume of 1.5 L is generally selected during the production process. Of course, quantitative tanks 2 with other capacities can also be selected.

[0039] During the production process, we can directly connect the water level detector 4 to the quantitative tank 2. At this time, when the drainage structure 5 is opened to drain water, the amount of water between the water level detector 4 and the quantitative tank 2 should also be additionally calculated when calculating the drainage volume each time.

[0040] In the actual production process, the water level detector 4 generally adopts Figure 1-3 The installation method shown, that is, the water level detector 4 (the water level detector 4 does not work for kerosene) is connected between the flow control structure 3 and the collection tank 1. This can simplify the structure of the equipment and avoid the liquid level fluctuation or backflow in the water level detector 4 caused by closing the flow control structure 3 and the balance valve 6 when the water level detector 4 is directly connected to the quantitative tank 2, resulting in instability of each drainage and affecting the calculation result of the water output.

[0041] Specifically, the water level detector 4 is an audible and visual water level alarm 41. When the water level detector 4 detects a signal, it will issue an alarm message to remind the operator to manually close the flow control structure 3 and the balancing valve 6, and open the drainage structure 5 under the quantitative tank 2. Generally, the drainage structure 5 is opened after the flow control structure 3 and the balancing valve are closed for 5 seconds.

[0042] More specifically, the installation height of the balancing valve 6 in Embodiment 1 of the present invention should not be higher than the installation height of the water level detector 4. This ensures that when the balancing valve 6 is manually closed, the amount of water between the balancing valve 6 and the quantitative tank 2 is fixed, further reducing the error of a single drainage amount.

[0043] In the present invention, a vacuum extraction structure 8 is provided on the collection tank 1, and the vacuum degree of the collection tank 1 is 42-48 mbar. The vacuum extraction structure 8 includes a vacuum pump 81 for extracting the gas in the collection tank 1 and an extraction valve 82 connected to the vacuum pump 81. During the operation of the gas phase drying device of the present invention, the vacuum pump 81 on the collection tank 1 is always turned on, and the vacuum degree of the collection tank 1 is 42-48 mbar by switching the exhaust valve 82. The water and kerosene mixed liquid condensed by the gas phase drying device enters the collection tank 1 through the condensate collection valve 11. Since the density of water is 1000 kg / m 3 , the density of kerosene is about 800kg / m 3 , the density of water is greater than that of kerosene. According to the principles of physics, stratification is formed, kerosene will float to the upper part of the collection tank 1, and water will sink to the bottom of the collection tank 1.

[0044] like Figure 1-3 As shown, in the present invention, a kerosene level detector 9 and an oil discharge mechanism 10 for discharging kerosene are provided on the collection tank 1. In the process of collecting water, the kerosene in the upper layer of the collection tank 1 will also increase. The kerosene level detector 9 usually adopts a kerosene level meter 91, and the kerosene level meter 91 is provided with an upper limit float 911 and a lower limit float 912. When the kerosene in the collection tank 1 reaches the upper limit float 911 level, the oil discharge mechanism 10 is opened to discharge the kerosene. When the kerosene level meter 91 detects that the tank oil in the collection reaches the lower limit float 912 level, the oil discharge mechanism 10 is closed to stop discharging the kerosene. The above process is repeated during production. The oil discharge mechanism 10 includes a kerosene discharge pump 101 and a kerosene discharge valve 102.

[0045] The method for measuring the water output of the kerosene gas phase drying equipment water output measuring device in embodiment 1 of the present invention comprises the following steps:

[0046] S1. Close the flow control structure 3 and the balancing valve 6 and open the drainage structure 5 below the quantitative tank 2 to ensure that the water in the pipeline below the flow control structure 3 and the balancing valve 6 and the water in the quantitative tank 2 are completely drained;

[0047] S2. Close the drainage structure 5, open the balancing valve 6, and after the air pressure in the metering tank 2 and the collecting tank 1 is balanced, open the flow control structure 3 to introduce the water at the bottom of the collecting tank 1 into the metering tank 2;

[0048] S3. After the water level detector 4 detects that the quantitative tank 2 is full of water, the balancing valve 6 and the flow control structure 3 are closed, and then the drainage structure 5 below the quantitative tank 2 is opened to drain water, and the water in the pipeline below the flow control structure 3 and the balancing valve 6 and the water in the quantitative tank 2 are completely drained, and the drainage and the amount of water discharged are recorded;

[0049] S4. Repeat the steps in S2 and S3, and record the number of drainages within a certain period of time, and calculate the hourly water output of the kerosene vapor drying equipment based on the number of drainages and the amount of water discharged each time.

[0050] If the water level detector 4 is directly connected to the quantitative tank 2, when the drainage structure 5 is opened for drainage, the amount of water between the water level detector 4 and the quantitative tank 2 should also be taken into account in calculating the drainage volume in S1 drainage and S3 each time.

[0051] Example 2

[0052] like Figure 2 As shown, the difference between Example 2 and Example 1 of the present invention is that the kerosene gas phase drying equipment water outlet measuring device in Example 2 also includes a control system 7, and the water level detector 4 and the balancing valve 6 are electrically connected to the control system 7 respectively. When the water level detector 4 detects that the quantitative tank 2 is full of water, the control system 7 controls the balancing valve 6 to close.

[0053] The structure in Example 2 of the present invention can realize semi-automatic control. When the water level detector 4 detects that the quantitative tank 2 is full of water, the control system 7 controls the balancing valve 6 to close, and the operator manually closes the flow control structure 3. In this way, no matter how the installation height of the balancing valve 6 is, each time the water level detector 4 detects that the quantitative tank 2 is full of water, the water content between the balancing valve 6 and the quantitative tank 2 is fixed. When the drainage structure 5 under the quantitative tank 2 is manually opened, the drainage volume of the water measuring device each time is also fixed, and will not be affected by the untimely closing of the flow control structure 3. In order to prevent the excess water above the balancing valve 6 in the pipeline 61 from being re-flowed into the collection tank 1 by the atmospheric pressure in the quantitative tank 2 for water-oil separation during the production process, affecting the speed of air pressure balance in the quantitative tank 2 and the collection tank 1, in order to improve production efficiency, the installation height of the balancing valve 6 is generally 2-5mm higher than the installation height of the water level detector 4.

[0054] In this embodiment, the method for measuring the water output of the kerosene gas phase drying equipment water output measuring device is the same as that of the first embodiment except that the control system 7 can be used to automatically control the water level detector 4 and the balancing valve 6.

[0055] Example 3

[0056] like Figure 3As shown, the difference between Example 3 of the present invention and Example 2 is that the flow control structure 3 and the drainage structure 5 in the water outlet measuring device of the kerosene gas phase drying equipment of Example 3 are also electrically connected to the control system 7 respectively. When the water level detector 4 detects that the quantitative tank 2 is full of water, the control system 7 controls the balance valve 6 and the flow control structure 3 to close, and after a certain period of static time (generally 5S), the control system 7 controls the drainage structure 5 to open for drainage; after the water in the pipeline below the flow control structure 3 and the balance valve 6 and the water in the quantitative tank 2 are completely emptied, the control system 7 records the drainage once; at the same time, the drainage structure 5 is controlled to close, the balance valve 6 is opened, and after the air pressure in the quantitative tank 2 and the collection tank 1 is balanced, the flow control structure 3 is opened to introduce the water at the bottom of the collection tank 1 into the quantitative tank 2; in this way, fully automatic circulation can be realized, no manual operation is required, and the operation time is more accurate, and the drainage volume each time is more accurate.

[0057] In the actual production process, the flow control structure 3, the drainage structure 5, and the balance valve 6 are all electromagnetic valves.

[0058] The method for measuring the water output of the water output measuring device of the kerosene vapor phase drying equipment in this embodiment is different from that in embodiment 2 in that the control system 7 is used in embodiment 3 to intelligently control the flow control structure 3, the water level detector 4, the drainage structure 5, and the balancing valve 6. In step S, each time the drainage structure 5 discharges water, the control system 7 records the drainage once and increases the recorded drainage volume. The controller records the water output in real time, and calculates the water output rate per ton of insulation weight per hour by combining the insulation weight of the product transformer and the water output volume counted once per hour, in units of L / th, and feeds back the current transformer insulation water output speed, thereby providing an accurate basis for the vapor phase drying equipment to enter the next operation stage.

[0059] The method for measuring the water output of the kerosene vapor drying equipment water output measuring device in this embodiment 3 also includes a drainage fault detection step, and the drainage fault detection includes an excessive drainage fault caused by a fault in the flow control structure 3 and the drainage structure 5, and a low water output fault caused by an abnormality in the vapor drying equipment (not shown in the figure).

[0060] Excessive drainage failure: In the actual application process, due to the failure of the flow control structure 3 and the drainage structure 5, the quantitative tank 2 cannot be discharged. For example, a 1.5L quantitative tank is drained three times in a row within 30 minutes (three times of continuous drainage is impossible under normal circumstances). The control system 7 will prompt a fault and notify the personnel for maintenance.

[0061] Low water output fault: The gas phase drying equipment normally dries the product, and the minimum water output of the insulating parts is calculated based on 3%. For example, 1000kg of insulating parts will have a minimum of 30kg of water output. If it is lower than this value, the control system 7 will prompt that the water output is too low, and prompt the personnel to check the gas phase drying equipment.
