Description

Technical Field

[0001] The present invention belongs to the field of technical detection of water balance, and provides a device for dynamically detecting the water balance of a spray tower. Background Art

[0002] As a commonly used device for industrial waste gas treatment, a spray tower pumps the spray liquid in the water tank to the top of the tower through a circulating water pump, and then sprays it into the tower body by a nozzle. The liquid contacts and absorbs the industrial waste gas discharged into the spray tower to achieve the function of waste gas treatment.

[0003] At present, the structure of the spray tower includes a water tank, a water replenishment port, a circulating pump, and a spray head. Water is replenished into the water tank through the water replenishment port, and the circulating pump transports the water in the water tank to the spray head and then sprays it out atomized. The industrial waste gas is treated by the atomized water. However, the water volume calculation in the above structure is mostly based on empirical estimates of parameters such as the head of the circulating pump and the designed air volume for waste gas treatment. The empirical estimated water volume is affected by multiple factors such as the specific usage scenario, model, and the actual working efficiency of the spray tower. It is difficult to ensure the accuracy and does not have a real-time monitoring function, and cannot provide data support for the results. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a device for dynamically detecting the water balance of a spray tower, which can real-time monitor the water level change, water replenishment volume, and water absorption volume in the spray tower, and provide theoretical and data support for the water volume detection results.

[0005] The technical solution of the present invention includes a water level detection module, a processing module, a water replenishment detection module, and a circulating water detection module. The water level measurement module includes a water level box and two electrodes. The two electrodes are respectively located on two opposite side walls inside the water level box, and one ends of the two electrodes are both above the highest water level line in the spray tower, and the other ends of the two electrodes are both below the lowest water level line in the spray tower. An opening is provided at the bottom of the water level box to allow the water in the spray tower to enter the water level box. The two electrodes detect the change in capacitance in the water level box, and the processing module calculates the change in water level through the change in capacitance. The water replenishment detection module includes a water replenishment detection probe, which is arranged at the water replenishment port of the spray tower. The water replenishment detection probe is used to measure the acting force of the water flow at the water replenishment port on the water replenishment detection probe. The water replenishment detection probe is connected to the processing module, and the processing module calculates the water flow velocity at the water replenishment port through the acting force of the water, and thus calculates the water replenishment volume within a fixed time period through the water flow velocity. The circulating water detection module includes a circulating water detection probe, which is arranged at the inlet of the circulating pump of the spray tower. The circulating water detection probe is used to measure the acting force of the water flow at the inlet of the circulating pump on the circulating water detection probe. The processing module calculates the water flow velocity at the inlet of the circulating pump through the acting force of the water, and thus calculates the water suction volume of the circulating pump within a fixed time period through the water flow velocity. The processing module is connected to the water level box, and the processing module sends the change in water level, the water replenishment volume, and the water suction volume to the display end for real-time monitoring.

[0006] Further, both the water replenishment detection probe and the circulating water detection probe include a fixing frame, a spring, a resistor, and a metal baffle. One end of the spring is connected to the fixing frame, the other end of the spring is connected to the metal baffle, and the metal baffle is slidably connected to the resistor, so that the acting force of the water drives the metal baffle to slide along the resistor, causing the resistor to change. The processing module calculates the acting force of the water according to the change in the resistor. The resistor is fixed on the fixing frame, and both the resistor and the metal baffle are connected to the processing module.

[0007] Further, a fixator is provided on the water replenishment detection probe, and the fixator is used to fix the water replenishment detection probe at the water replenishment port of the spray tower.

[0008] Further, the fixator includes a straight pipe and a flared hose. The flared hose is connected to the straight pipe. The water replenishment detection probe is fixed in the straight pipe through a fixing wire, and the flared hose is connected to the water replenishment port of the spray tower in a matching manner.

[0009] Further, an electromagnetic attachment is provided on the flared hose, and the electromagnetic attachment is located at the end of the flared hose away from the straight pipe. The electromagnetic attachment enables the flared hose to be connected to the water tank wall outside the water inlet pipe.

[0010] Further, the calculation formula for the water replenishment volume or the water suction volume is: , Where L is the water absorption or makeup water volume, V is the liquid flow rate, T is the measurement duration, A is the cross-sectional area of the detection position, and the calculation formula for the liquid flow rate V is: , Where F is the force of water, is the liquid density.

[0011] Furthermore, it also includes a detection box, which is connected to the side wall of the water level box and is used to place the processing module.

[0012] Furthermore, it also includes a lifting device, which is connected to the detection box to drive the detection box to move up and down in the spray tower.

[0013] The technical solution provided by the embodiment of the present invention has the following advantages compared with the prior art: 1. When the dynamic water balance detection device of the present invention is used, first place the water level box in the spray tower through the fixing structure so that the water level box is immersed in water, so that one end of both electrodes is above the maximum water level in the spray tower and the other end of both electrodes is below the minimum water level in the spray tower. Water enters the water level box through the opening of the water level box. The change in water level will cause the capacitance between the two electrodes to change. The processing module calculates the change in water level according to the change in capacitance. Secondly, fix the makeup water detection probe at the makeup water inlet of the spray tower to measure the force of water at the makeup water inlet, and fix the circulating water detection probe at the inlet of the circulating pump of the spray tower to measure the force of water at the inlet of the circulating pump. The processing module calculates the water flow rate at the makeup water inlet and the water flow rate at the inlet of the circulating pump according to the force of water at the makeup water inlet and the force of water at the inlet of the circulating pump, and calculates the water inflow volume or water absorption volume within a fixed time period through the water flow rate respectively, and then sends it to the display end for real-time display. Compared with the prior art, it can monitor the water level change, makeup water volume and water absorption volume in real time, ensuring the accuracy of data.

[0014] 2. The dynamic water balance detection device of the present invention detects the force of water through the detection probe, calculates the water flow rate according to the force of water, and thus calculates the makeup water volume or water absorption volume. Compared with measuring by setting a meter on the spray tower, the present invention can be disassembled and placed in different spray towers for measurement, and is not limited by factors such as specific usage scenarios, models and the actual working efficiency of the spray tower, with strong versatility.

[0021] In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality of" refers to two or more.

[0022] As Figure 1 and Figure 2 As shown, the present invention provides a dynamic water balance detection device for a spray tower, which is placed in the spray tower 5 and includes a water level detection module, a processing module 8, a makeup water detection module, and a circulating water detection module; the water level measurement module includes a water level box 2 and two electrodes 3. The two electrodes 3 are respectively located on two opposite side walls inside the water level box 2, and one ends of the two electrodes 3 are both above the highest water level line in the spray tower 5, and the other ends of the two electrodes 3 are both below the lowest water level line in the spray tower 5. An opening 4 is provided at the bottom of the water level box 2 to allow the water in the spray tower 5 to enter the water level box 2. The two electrodes 3 detect the change in capacitance in the water level box 2. The processing module 8 calculates the change in water level through the change in capacitance. The makeup water detection module includes a makeup water detection probe 6, and the makeup water detection probe 6 is arranged at the makeup water inlet of the spray tower 5. The makeup water detection probe 6 is used to measure the acting force of the water flow at the makeup water inlet on the makeup water detection probe 6. The makeup water detection probe 6 is connected to the processing module 8, and the processing module 8 calculates the water flow velocity at the makeup water inlet through the acting force of the water, and thus calculates the makeup water volume within a fixed time period through the water flow velocity. The circulating water detection module includes a circulating water detection probe 7, and the circulating water detection probe 7 is arranged at the inlet of the circulating pump 18 in the spray tower 5. The circulating water detection probe 7 is used to measure the acting force of the water flow at the inlet of the circulating pump 18 on the circulating water detection probe 7. The processing module 8 calculates the water flow velocity at the inlet of the circulating pump 18 through the acting force of the water, and thus calculates the water suction volume of the circulating pump 18 within a fixed time period through the water flow velocity. The processing module 8 is connected to the water level box 2, and the processing module 8 sends the change in water level, the makeup water volume, and the water suction volume to the display end for real-time monitoring.

[0023] When the dynamic water balance detection device of the present invention is in use, first place the water level box 2 in the spray tower 5 through the fixing structure, so that the water level box 2 is immersed in water, so that one end of each of the two electrodes 3 is above the maximum water level in the spray tower 5, and the other end of each of the two electrodes 3 is below the minimum water level in the spray tower 5. Water enters the water level box 2 through the opening 4 of the water level box 2. The change in water level will cause the capacitance between the two electrodes 3 to change. The processing module 8 calculates the change in water level according to the change in capacitance. Secondly, fix the makeup water detection probe 6 at the makeup water inlet of the spray tower 5 to measure the force of the water at the makeup water inlet, and fix the circulating water detection probe 7 at the inlet of the circulating pump 18 of the spray tower 5 to measure the force of the water at the inlet of the circulating pump 18. The processing module 8 calculates the flow rate of the water at the makeup water inlet and the flow rate of the water at the inlet of the circulating pump 18 according to the force of the water at the makeup water inlet and the force of the water at the inlet of the circulating pump 18, and calculates the water inflow or water absorption volume within a fixed time period respectively through the water flow rate, and then sends it to the display end for real-time display. Compared with the prior art, it can monitor the water level change, makeup water volume and water absorption volume in real time, and ensure the accuracy of the data.

[0024] Specifically, when the water level changes, the total dielectric constant value between the two motors changes with the water level, thereby causing the capacitance between the two electrodes 3 to change. The processing module 8 calculates the water level change amount according to the capacitance change. When the water level rises, the calculated water level change amount value is positive, and when the water level drops, the calculated water level change amount value is negative.

[0025] It can be understood that in order to test the water force, the makeup water detection probe 6 and the circulating water detection probe 7 can be pressure sensors, force measuring sensors or other devices that can measure force.

[0026] Optionally, it further includes a detection box 1. The detection box 1 is connected to the side wall of the water level box 2. The detection box 1 is made of rubber, and the detection box 11 is used to place the processing module 8.

[0027] Optionally, such as Figure 2 and Figure 6As shown in the figure, the processing module 8 includes a power supply 81, an electrical signal conversion device 82, a first signal transmitter / receiver 83, and a remote control terminal. The remote control terminal includes a second signal transmitter / receiver 84, a display screen 85, a key 86, a switch 87, and a transmission interface 88. The power supply 81 supplies power to the electrical signal conversion device 82 and the first signal transmitter / receiver 83. The electrical signal conversion device 82 converts the capacitance change and resistance change into electrical signals and transmits them through the first signal transmitter / receiver 83. The second signal transmitter / receiver 84 receives the signals and transmits them to the remote control terminal. The remote control terminal calculates the water force at the water replenishment port and the water force at the inlet of the circulation pump 18 according to the resistance changes of the water replenishment detection probe 6 and the circulating water detection probe 7, thereby calculating the water flow rate at the water replenishment port and the water flow rate at the inlet of the circulation pump 18, and calculates the water intake or water absorption volume within a fixed time period based on the water flow rate respectively, and calculates the water level change according to the change in capacitance. The display screen 85 is used to display the water replenishment volume, water absorption volume, and water level change. The key is used to select one of the water replenishment volume, water absorption volume, and water level change and enter to view detailed information. The switch 87 controls the opening or closing of the remote control terminal. The transmission interface 88 is used to transmit the water replenishment volume, water absorption volume, and water level change to the required equipment, and specifically, the staff selects the equipment according to actual needs.

[0028] Optionally, several detection probes can be set according to different detection positions.

[0029] In the embodiment provided by the present invention, as Figure 3 shown, both the water replenishment detection probe 6 and the circulating water detection probe 7 include a fixing frame 9, a spring 10, a resistor 11, and a metal baffle 12. One end of the spring 10 is connected to the fixing frame 9, the other end of the spring 10 is connected to the metal baffle 12, and the metal baffle 12 is slidably connected to the resistor 11, so that the water force drives the metal baffle 12 to slide along the resistor 11, causing the resistance to change. The processing module calculates the water force according to the resistance change. The resistor 11 is fixed on the fixing frame 9, and both the resistor 11 and the metal baffle 12 are connected to the processing module 8.

[0030] Specifically, when water flows through the detection probe, the water will impact the metal baffle 12 to drive the metal baffle 12 to slide on the resistor 11, so that the resistor 11 changes. The processing module 8 calculates the water force according to the change in the resistor 11.

[0031] It can be understood that the functions of the spring 10 are: one is to support the metal baffle 12 to prevent the metal baffle 12 from being slidably connected to the resistor 11 only on one side, and when encountering the water force, the metal baffle 12 tilts, resulting in inaccurate measurement results; the other is to drive the metal baffle 12 to reset when the detection is completed.

[0032] It can be understood that the acting force of water includes water pressure and water tension, and which specific type it belongs to is determined according to the installation position of the detection probe and the water flow direction. For example, when the water replenishment detection probe 6 is placed at the water replenishment port, the water flows into the spray tower 5 and impacts the water replenishment detection probe 6, causing the metal baffle 12 to move in the direction of the compression spring 10. At this time, the acting force of water is water pressure. On the contrary, if it causes the metal baffle 12 to move in the direction of the tension spring 10, the acting force of water is water tension.

[0033] In the embodiment provided by the present invention, a fixator 13 is provided on the water replenishment detection probe 6, and the fixator 13 is used to fix the water replenishment detection probe 6 at the water replenishment port of the spray tower 5.

[0034] It can be understood that since the water at the water replenishment port enters the spray tower 5, and the water replenishment detection probe 6 is connected to the detection box 1 and is also located in the spray tower 5. If the water replenishment detection probe 6 is not fixed, the water at the water replenishment port will wash away the water replenishment detection probe 6, resulting in the inability of the water replenishment detection probe 6 to perform detection. Similarly, the circulating water detection probe 7 may not need to use the fixator 13 because the circulating pump 18 sucks water, and the circulating water detection probe 7 is pulled by a wire, so that the circulating water detection probe 7 can always be located at the inlet of the circulating pump 18. Of course, it is also possible to use a fixed probe for the circulating water detection probe 7 to further fix it.

[0035] In the embodiment provided by the present invention, as Figure 4 and Figure 5 shown, the fixator 13 includes a straight pipe 14 and a flared hose 15. The flared hose 15 is connected to the straight pipe 14. The water replenishment detection probe 6 is fixed in the straight pipe 14 through a fixing wire 131, and the flared hose 15 is connected to the water replenishment port of the spray tower 5 in a matching manner.

[0036] It can be understood that the caliber of the flared hose 15 can be adjusted according to the caliber of the water inlet pipe at the water replenishment port to adapt to water replenishment ports of different sizes, so that the present invention can adapt to different spray towers 5.

[0037] In the embodiment provided by the present invention, an electromagnetic attachment 16 is provided on the flared hose 15. The electromagnetic attachment 16 is located at one end of the flared hose 15 away from the straight pipe, and the electromagnetic attachment 16 is used to connect the flared hose 15 to the water tank wall outside the water inlet pipe.

[0038] It can be understood that since the water continuously impacts the water replenishment detection probe 6, it is easy for the fixator 13 to detach from the water replenishment port. Therefore, the flared hose 15 is adsorbed on the side wall of the spray tower 5 through the electromagnetic attachment 16, and at the same time, the flared hose 15 is sleeved on the water replenishment port, which can not only ensure detection but also prevent the fixator 13 from falling off.

[0039] In the embodiment provided by the present invention, the calculation formula for the water replenishment amount or water absorption amount is: , where L is the water absorption or makeup water volume, V is the liquid flow rate, T is the measurement duration, A is the cross-sectional area of the detection position, and the calculation formula for the liquid flow rate V is: , where F is the acting force of water, is the liquid density.

[0040] Specifically, the detection probe detects the acting force of water, and then through the acting force of water and the flow rate , the flow rate at the detection position is calculated by the formula , and the acting force of water The calculation formula is as follows: , Correspondingly, the flow rate is calculated by the following formula: , In the formula, represents the acting force of water detected by the detection probe, represents the liquid density, represents the pipe area at the detection position, represents the flow rate at the detection position.

[0041] Correspondingly, the water volume is calculated by the following formula: , In the formula, represents the pipe area at the detection position, represents the flow rate at the detection position, represents the duration.

[0042] The device water level detection module detects the water level change in the water tank in the spray tower, and then calculates the overall water volume change of the water tank water use unit through the water tank water level change, and calculates the spray return water volume based on the water volume balance formula. The water volume balance formula is as follows: , In the formula, represents the makeup water volume at the makeup water port, represents the spray return water volume, represents the water absorption volume of the circulation pump, represents the increased water volume calculated from the rise of the water tank water level (negative when the water tank water level drops).

[0043] Among them, the increased water volume is calculated by the following formula: , In the formula, represents the rising height of the water level in the water tank, represents the bottom area of the water tank, represents the duration.

[0044] Correspondingly, the spray return water volume is calculated by the following formula: , Based on the above detection and calculation results, the water inlet volume of the water replenishing port, the water suction volume of the circulation pump, and the spray return water volume of the spray tower can be obtained. Each water volume and detection data are displayed on the display.

[0045] In the embodiment provided by the present invention, as Figure 1 shown, it further includes a lifting device 17. The lifting device 17 is connected to the detection box 1 to drive the detection box 1 to move up and down in the spray tower 5.

[0046] It can be understood that the detection box 1 can be driven by the lifting device 17 to any height position in the spray tower 5 to adapt to different water levels and different spray towers 5.

[0047] When actually using this device: The first step is to externally add multiple detection probes on the detection floating box according to actual detection requirements. When detecting the water pressure of the water replenishing port, a probe fixer 13 needs to be used on the detection probe. Open the water inlet of the device and put it into the water tank from the upper opening of the water tank of the spray tower 5. After the water inlet enters the water, the internal and external water levels are kept consistent and stable, and then the capacitance change between the two electrodes 3 is detected by two motors; The second step is to place the circulating water detection probe 7 at the water pumping pipeline opening of the circulation pump 18. Under the action of the water pulling force, the probe automatically enters the pipeline for water force detection; The third step is to adjust the diameter of the bellmouth hose 15 of the probe fixer 13 according to the diameter of the water inlet pipeline of the water replenishing port. The detection probe in the straight pipe 14 section of the fixer 13 is adsorbed on the water inlet pipeline of the water replenishing port by the electromagnetic adsorption accessory 16 for water force detection.

[0048] The fourth step is that the processing module 8 calculates the water level change and water flow rate through the capacitance change and water force, then calculates the water replenishing volume and water suction volume according to the water flow rate, and finally sends them to the display end for real-time monitoring.

[0049] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent in such a process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising that element.

[0050] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made.
