Description

Technical Field

[0001] This invention relates to an improvement in filter bag detection technology, belonging to the field of exhaust gas filtration, and particularly to a vibration positioning type flow filter bag detection system. Background Technology

[0002] Currently, thermal power plants need to emit exhaust gases into the air during operation, requiring filter bags to filter these gases. These filter bags operate continuously under high temperatures, and during use, mechanical wear occurs due to contact with the filter cages, leading to damage. Furthermore, the filter bags require air cleaning using spray guns, which physically damages the bags. Filter bags need to be replaced every three to four years. However, currently, replacing filter bags in thermal power plants requires shutting down the generator, resulting in significant economic losses and inconvenience to residents. Therefore, it is urgent to inspect the filter bags in power plants. Firstly, this inspection should determine the extent of damage and whether it meets repair standards; secondly, it should pinpoint the location of the damage and determine the repair area.

[0003] Chinese patent application CN202011491697.9, filed on December 16, 2020, discloses a system for detecting filter bag damage based on a charge method, relating to the field of baghouse dust collector technology, for real-time monitoring of filter bag damage. It includes a charge sensing module, a signal transmission module, and a signal processing module. The charge sensing module continuously detects charge signals; the signal transmission module transmits the detected charge signals to the signal processing module; the data processing module includes a charge amplifier, a filter circuit, and an analog-to-digital converter circuit, which sequentially amplifies, filters, and converts the charge signals to obtain digital signals; it also includes a controller, which obtains the dust concentration change curve at the outlet side of each filter bag based on the correspondence between the digital signal and dust concentration, and determines whether the filter bag is damaged based on the dust concentration change curve corresponding to each filter bag. This invention is suitable for relatively narrow baghouse dust collectors, allowing real-time monitoring of filter bag damage. However, the prior art relies excessively on the magnitude of the charge carried by dust after collision, leading to reduced detection accuracy and an inability to accurately locate the filter bag damage position.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem in the prior art that it is impossible to accurately locate the location of filter bag damage, and to provide a vibration positioning type flow filter bag detection system that can accurately locate the location of filter bag damage.

[0006] To achieve the above objectives, the technical solution of the present invention is: a vibration positioning type flow filter bag detection system, the vibration positioning type flow filter bag detection system comprising a bag body, a first clamping assembly, a second clamping assembly, a third clamping assembly, a fourth clamping assembly, a detection mechanism, a funnel, and a measuring cylinder;

[0007] The bottom of the first clamping component and the top of the second clamping component are clamped and fixed to one end of the bag body, and the bottom of the third clamping component and the top of the fourth clamping component are clamped and fixed to the other end of the bag body.

[0008] The top of the bag is provided with a detection structure, which includes multiple detection units. The bottom of the bag is provided with multiple funnels. The positions of the multiple detection units and the multiple funnels correspond to each other. The corresponding detection units and funnels clamp the bag. The funnels are mounted on a tray.

[0009] A vibration mechanism is provided on the front of the bag body, located on the right side of the detection structure, and the vibration mechanism is clamped to the bag body.

[0010] The detection structure moves equidistantly from left to right along the bag, and the detection structure moves synchronously with the funnel.

[0011] The clamping assembly includes an upper left clamping plate and an upper left support rod;

[0012] The dual clamping assembly includes a lower left clamping plate and a lower left support rod;

[0013] The three-clamp assembly includes an upper right clamping plate and an upper right support rod;

[0014] The four-clamp assembly includes a lower right clamping plate and a lower right support rod;

[0015] The top center of the upper left clamping plate is connected to the bottom of the upper left support rod, the bottom center of the lower left clamping plate is connected to the top of the lower left support rod, the top center of the upper right clamping plate is connected to the bottom of the upper right support rod, and the bottom center of the lower right clamping plate is connected to the top of the lower right support rod.

[0016] The bottom of the upper left clamp and the top of the lower left clamp are clamped and fixed to one end of the bag body, and the bottom of the upper right clamp and the top of the lower right clamp are clamped and fixed to the other end of the bag body.

[0017] The upper left clamp, lower left clamp, upper right clamp, and lower right clamp are all the same size and their width is greater than the width of the bag. The upper left support rod, lower left support rod, upper right support rod, and lower right support rod are all the same size.

[0018] The contact surfaces of the upper left clamp, lower left clamp, upper right clamp, and lower right clamp with the bag body are treated with a mirror finish.

[0019] The detection structure includes four detection units and four nozzles. The bottom of the detection unit is connected to the top of the nozzle, and the four detection units are interconnected. The top of the detection unit has a through hole that is connected to the nozzle. The diameter between the through hole and the nozzle increases in size.

[0020] The top of the tray has four mounting holes, and each funnel is installed in the corresponding mounting hole. The bottom of the funnel is located in the mounting hole and connected to the top of the measuring cylinder.

[0021] The diameter of the nozzle bottom is the same as the diameter of the funnel top, the diameter of the funnel bottom is the same as the diameter of the measuring cylinder, the top of the funnel fits against the bottom of the bag, and the bottom of the nozzle fits against the top of the bag. Each funnel and each nozzle correspond to clamp the bag.

[0022] There are four funnels arranged in a rectangular pattern, and four detection units are arranged in a rectangular pattern. Each funnel, detection unit, and scale cylinder are arranged in a one-to-one correspondence.

[0023] The bottom of the vibration mechanism is equipped with a vibrating plate, and the vibrating plate is provided with multiple vibration protrusions.

[0024] The vibrating protrusions are curved on the side closest to the bag body, and multiple vibrating protrusions are distributed around the vibrating plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In a vibration positioning type flow filter bag detection system of the present invention, the bottom of a first clamping component and the top of a second clamping component are clamped and fixed to one end of the bag body, and the bottom of a third clamping component and the top of a fourth clamping component are clamped and fixed to the other end of the bag body; a detection structure is provided on the top of the bag body, and multiple funnels are provided on the bottom of the bag body. The detection structure and the multiple funnels are positioned correspondingly, and the detection structure and the funnels clamp the bag body. The funnels are mounted on a support plate, and multiple graduated cylinders are provided on the bottom of the support plate. Each funnel and graduated cylinder are connected in a one-to-one correspondence. The first clamping component and the second clamping component clamp the left end of the bag body, and the third clamping component... The four-clamp assembly holds the right end of the bag, while the detection mechanism and funnel hold the portion of the bag to be tested. Detection liquid is injected into the detection mechanism, dripping onto the bag. After a period of time, the liquid permeates the bag and falls into the corresponding funnel, then flows into the graduated cylinders. By comparing the flow rates of the detection liquid in the four graduated cylinders within the same time frame, the location of the damage can be determined, allowing for precise localization. When the flow rate at a given location is similar, the system moves to the next detection position, comparing the flow rate at the previous position with the flow rate difference between the four graduated cylinders to determine if damage has occurred at that location. Therefore, this design offers precise location and is easy to operate.

[0027] 2. In the vibration-positioning flow filter bag detection system of the present invention, a vibration mechanism is arranged on the front of the bag body, located on the right side of the detection structure. The vibration mechanism is clamped to the bag body, and a vibration plate is installed at the bottom of the vibration mechanism. Multiple vibration protrusions are arranged on the vibration plate; the side of the vibration protrusions closest to the bag body is arc-shaped. The multiple vibration protrusions are distributed around the vibration plate. By gently shaking the bag body by hand, the penetration rate of the detection liquid can be accelerated. The vibration protrusions reduce friction on the bag body, avoiding unnecessary damage to the bag body during the detection process. Therefore, this design has high detection efficiency and is easy to use.

[0028] 3. In the vibration positioning type flow filter bag detection system of this invention, the upper left clamping plate, lower left clamping plate, upper right clamping plate, and lower right clamping plate have the same structural size, and their width is greater than the width of the bag body. The upper left support rod, lower left support rod, upper right support rod, and lower right support rod have the same structural size. The contact surfaces of the upper left clamping plate, lower left clamping plate, upper right clamping plate, and lower right clamping plate with the bag body are mirror-finished. The upper left clamping plate and lower left clamping plate can move with the detection position of the detection mechanism, thereby ensuring that the tautness of the entire bag body remains unchanged. The mirror-finished clamping plates reduce friction during movement, avoiding unnecessary damage to the bag body caused by clamping plate friction, which would affect normal measurement. Therefore, this design is safe to use and has a long service life. Attached Figure Description

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] See Figures 1 to 12 A vibration positioning type flow filter bag detection system, the vibration positioning type flow filter bag detection system includes a bag body 1, a clamping component A, a clamping component B, a clamping component C, a clamping component D, a detection mechanism 10, a funnel 11 and a measuring cylinder 13;

[0044] The bottom of the first clamping component A and the top of the second clamping component B are clamped and fixed to one end of the bag body 1, and the bottom of the third clamping component C and the top of the fourth clamping component D are clamped and fixed to the other end of the bag body 1.

[0045] The top of the bag body 1 is provided with a detection structure 10, which includes multiple detection units 101. The bottom of the bag body 1 is provided with multiple funnels 11. The positions of the multiple detection units 101 and the multiple funnels 11 are corresponding. The corresponding detection units 101 and funnels 11 clamp the bag body 1. The funnels 11 are installed on the tray 12. The bottom of the tray 12 is provided with multiple measuring cylinders 13. Each funnel 11 and measuring cylinder 13 are connected in a one-to-one correspondence.

[0046] A vibration mechanism 14 is provided on the front of the bag body 1, located to the right of the detection structure 10, and the vibration mechanism 14 is clamped to the bag body 1.

[0047] The detection structure 10 moves equidistantly from left to right along the bag body 1, and the detection structure 10 moves synchronously with the funnel 11.

[0049] The dual clamping assembly B includes a lower left clamping plate 4 and a lower left support rod 5;

[0050] The three-clamping assembly C includes an upper right clamping plate 6 and an upper right support rod 7;

[0051] The four-clamp assembly D includes a lower right clamping plate 8 and a lower right support rod 9;

[0052] The top center of the upper left clamping plate 2 is connected to the bottom of the upper left support rod 3, the bottom center of the lower left clamping plate 4 is connected to the top of the lower left support rod 5, the top center of the upper right clamping plate 6 is connected to the bottom of the upper right support rod 7, and the bottom center of the lower right clamping plate 8 is connected to the top of the lower right support rod 9.

[0053] The bottom of the upper left clamping plate 2 and the top of the lower left clamping plate 4 are clamped and fixed to one end of the bag body 1, and the bottom of the upper right clamping plate 6 and the top of the lower right clamping plate 8 are clamped and fixed to the other end of the bag body 1.

[0054] The upper left clamping plate 2, lower left clamping plate 4, upper right clamping plate 6 and lower right clamping plate 8 have the same structural size and their width is greater than the width of the bag body 1. The upper left support rod 3, lower left support rod 5, upper right support rod 7 and lower right support rod 9 have the same structural size.

[0055] The contact surfaces of the upper left clamping plate 2, lower left clamping plate 4, upper right clamping plate 6, and lower right clamping plate 8 with the bag body 1 are treated with a mirror finish.

[0056] The detection structure 10 includes four detection units 101 and four nozzles 103. The bottom of the detection unit 101 is connected to the top of the nozzle 103. The four detection units 101 are interconnected. A through hole 102 is opened on the top of the detection unit 101. The through hole 102 is connected to the nozzle 103. The diameter between the through hole 102 and the nozzle 103 increases.

[0057] The top of the tray 12 has four mounting openings 121, and each funnel 11 is installed in the corresponding mounting opening 121. The bottom of the funnel 11 is located in the mounting opening 121 and connected to the top of the measuring cylinder 13.

[0058] The bottom diameter of the nozzle 103 is the same as the top diameter of the funnel 11, and the bottom diameter of the funnel 11 is the same as the diameter of the measuring cylinder 13. The top of the funnel 11 is attached to the bottom of the bag body 1, and the bottom of the nozzle 103 is attached to the top of the bag body 1. Each funnel 11 and each nozzle 103 clamp the bag body 1 accordingly.

[0059] There are four funnels 11 arranged in a rectangular pattern, and four detection units 101 are arranged in a rectangular pattern. Each funnel 11, detection unit 101, and scale cylinder 13 are arranged in a one-to-one correspondence.

[0060] The bottom of the vibration mechanism 14 is equipped with a vibratory plate 141, and the vibratory plate 141 is provided with a plurality of vibration protrusions 142.

[0061] The vibrating protrusion 142 has an arc-shaped surface on the side near the bag body 1, and multiple vibrating protrusions 142 are distributed around the vibrating plate 141.

[0062] The principle of this invention is explained as follows: The left end of the bag body 1 is clamped by the upper left clamping plate 2 and the lower left clamping plate 4, and the right end of the bag body 1 is clamped by the upper right clamping plate 6 and the lower right clamping plate 8, so that the entire bag body 1 is kept in a taut, disc-shaped state. Then, an area to be tested is selected on the bag body 1, and the area to be tested on the bag body 1 is clamped by the individual detection unit 101 and the individual funnel 11. Then, detection liquid is injected into all detection units 101. After passing through the nozzle 103, the detection liquid permeates the bag body 1 and falls into the corresponding funnel 11. The liquid then flows into the graduated cylinder 13. At the same time, the handheld vibration mechanism 14 slightly vibrates the bag 1 located near the area being tested, accelerating the penetration rate of the test liquid. After a preset time, the flow rate of the test liquid in the four graduated cylinders 13 is recorded respectively. The flow rate values ​​are then compared to determine whether there is any damage to the area being tested and the specific location of the damage. Subsequently, the funnel is moved to continue testing the next area of ​​the bag and the corresponding flow rate value is recorded until all bags have been tested and all flow rate values ​​are recorded.

[0063] Example 1:

[0064] A vibration-positioning type flow filter bag detection system includes a bag body 1, a clamping assembly A, a clamping assembly B, a clamping assembly C, a clamping assembly D, a detection mechanism 10, a funnel 11, and a measuring cylinder 13. The bottom of the clamping assembly A and the top of the clamping assembly B are clamped and fixed to one end of the bag body 1, and the bottom of the clamping assembly C and the top of the clamping assembly D are clamped and fixed to the other end of the bag body 1. A detection structure 10 is provided on the top of the bag body 1, and the detection structure 10 includes multiple detection units 101. The bottom of the bag body 1... The unit is equipped with multiple funnels 11, and multiple detection units 101 are positioned corresponding to the multiple funnels 11. The corresponding detection units 101 and funnels 11 clamp the bag body 1. The funnels 11 are mounted on a tray 12, and multiple measuring cylinders 13 are provided at the bottom of the tray 12. Each funnel 11 and measuring cylinder 13 is connected in a one-to-one correspondence. A vibration mechanism 14 is provided on the front of the bag body 1, located to the right of the detection structure 10. The vibration mechanism 14 is clamped to the bag body 1. The detection structure 10 moves equidistantly from left to right along the bag body 1, and the detection structure 10 moves synchronously with the funnels 11.

[0065] In application: The left end of bag 1 is held by clamping component A and clamping component B, and the right end of bag 1 is held by clamping component C and clamping component D, so that the entire bag 1 is kept in a taut, disc-shaped state. Then, an area to be tested is selected on bag 1, and the area to be tested on bag 1 is clamped by individual detection unit 101 and individual funnel 11. Then, detection liquid is injected into all detection units 101 of detection mechanism 10. The detection liquid permeates bag 1 and falls into the corresponding funnel 11, and then flows into the scale cylinder 13. At the same time, the handheld vibration mechanism 14 slightly vibrates bag 1 near the area to be tested to accelerate the penetration rate of detection liquid. After a preset time, the flow rate of detection liquid in the four scale cylinders 13 is recorded respectively. Then, the flow rate values ​​are compared to determine whether there is damage to the area to be tested and the specific location of the damage. Subsequently, move 10 and the funnel to continue testing the next area of ​​the bag and record the corresponding flow rate value until all bags are tested and all flow rate values ​​are recorded. There are two possible ways to process the obtained flow values:

[0066] The first method involves comparing the four flow values ​​in each region. If a sudden increase is found, it is determined that there is damage at the corresponding location.

[0067] The second method involves first averaging the flow rate of each area to obtain the average value of each area, then plotting the flow rate change curve of the entire bag 1, and then observing the curve to find the parts where the flow rate suddenly increases, which are the damaged areas.

[0068] Example 2:

[0069] Example 2 is basically the same as Example 1, except that:

[0070] A vibration positioning type flow filter bag detection system includes a clamping assembly A comprising an upper left clamping plate 2 and an upper left support rod 3; a second clamping assembly B comprising a lower left clamping plate 4 and a lower left support rod 5; a third clamping assembly C comprising an upper right clamping plate 6 and an upper right support rod 7; and a fourth clamping assembly D comprising a lower right clamping plate 8 and a lower right support rod 9.

The bottom of the upper left clamping plate 2 and the top of the lower left clamping plate 4 are clamped and fixed to one end of the bag body 1. The upper right clamping plate 6... The bottom and the top of the lower right clamping plate 8 are clamped and fixed to the other end of the bag body 1; the upper left clamping plate 2, the lower left clamping plate 4, the upper right clamping plate 6 and the lower right clamping plate 8 have the same structural size and their width is greater than the width of the bag body 1; the upper left support rod 3, the lower left support rod 5, the upper right support rod 7 and the lower right support rod 9 have the same structural size; the contact surfaces of the upper left clamping plate 2, the lower left clamping plate 4, the upper right clamping plate 6 and the lower right clamping plate 8 with the bag body 1 are treated with mirror finish; the upper left clamping plate 2 and the lower left clamping plate 4 can move with the detection position of the detection mechanism 10, thereby ensuring that the straightening effect of the entire bag body 1 remains unchanged; the mirror-finished clamping plates reduce the friction during movement and avoid unnecessary damage to the bag body 1 caused by the friction of the clamping plates.

[0071] Example 3:

[0072] Example 3 is basically the same as Example 1, except that:

[0073] A vibration-positioning type flow filter bag detection system includes a detection structure 10 comprising four detection units 101 and four nozzles 103. The bottom of each detection unit 101 is connected to the top of each nozzle 103, and the four detection units 101 are interconnected. Each detection unit 101 has a through hole 102 at its top, which communicates with the nozzle 103. The diameter of the through hole 102 increases from the nozzle 103. A support plate 12 has four mounting ports 121 at its top, and each funnel 11 is installed in its corresponding mounting port 121. The bottom of each funnel 11 is located within the mounting port 121 and connected to the top of a graduated cylinder 13. The bottom diameter of each nozzle 103 is the same as the top diameter of the funnel 11. The bottom diameter of the funnel 11 is the same as the diameter of the measuring cylinder 13. The top of the funnel 11 is attached to the bottom of the bag body 1, and the bottom of the nozzle 103 is attached to the top of the bag body 1. Each funnel 11 and each nozzle 103 clamp the bag body 1. There are four funnels 11 arranged in a rectangular pattern, and four detection units 101 are arranged in a rectangular pattern. Each funnel 11, detection unit 101, and measuring cylinder 13 are arranged in a one-to-one correspondence. A vibration plate 141 is installed at the bottom of the vibration mechanism 14. Multiple vibration protrusions 142 are provided on the vibration plate 141. The side of the vibration protrusion 142 closest to the bag body 1 is an arc-shaped surface, and multiple vibration protrusions 142 are distributed around the vibration plate 141.

[0074] Example 4:

[0075] Example 4 is basically the same as Example 1, except that:

[0076] A vibration positioning type flow filter bag detection system, the formula for the resistance of filter bag 1 when gas passes through filter bag 1 is as follows:

[0077] ΔP=ξ•μ•ν Formula 1

[0078] Where ξ is the resistance coefficient of the filter bag, m-1;

[0079] μ is the gas dynamic viscosity coefficient, Pa•s; (1.87×10⁻⁵ Pa•s)

[0080] ν is the average filtration velocity, in m / s.

[0081] From the gas flow rate formula, the formula for the filtered air flow rate is as follows:

[0082] Formula 2: Q = S•ν

[0083] Q is the gas volume flow rate into the filter bag, m3 / s;

[0084] S represents the filtration area, in m².

[0085] From Formula 1 and Formula 2, we can obtain that

[0086] ΔP=ξ•μ•Q / S

[0087] Where ξ=(K•L) / (α∙S), K is the resistance factor of the gas passing through the filter bag; L is the thickness of the filter bag, in meters; and α is the porosity of the filter bag.

[0088] The relationship between the air resistance of the filter bag and the flow rate of the filtered gas is as follows:

[0089] ΔP=K∙(μ∙L) / (α∙S^2)∙Q.

[0090] Example 5

[0091] Example 5 is basically the same as Example 1, except that:

[0092] like Figure 12 In addition to moving from left to right, the movement trajectory of the detection mechanism 10 also includes a movement trajectory from bottom to top. When the detection mechanism 10 moves from bottom to top and then to the right side, the upper left clamp 2 and the lower left clamp 4 will move to a position close to the detection mechanism 10, so that the entire bag 1 is always kept in a taut, disc-shaped state, ensuring that the detection data is more accurate.

The four detection units (101) are interconnected. A through hole (102) is opened on the top of the detection unit (101). The through hole (102) is connected to the nozzle (103). The diameter between the through hole (102) and the nozzle (103) increases. The top of the tray (12) is provided with four mounting ports (121), and each funnel (11) is installed in the corresponding mounting port (121). The bottom of the funnel (11) is located in the mounting port (121) and connected to the top of the measuring cylinder (13). The bottom diameter of the nozzle (103) is the same as the top diameter of the funnel (11), the bottom diameter of the funnel (11) is the same as the diameter of the measuring cylinder (13), the top of the funnel (11) is attached to the bottom of the bag body (1), the bottom of the nozzle (103) is attached to the top of the bag body (1), and each funnel (11) and each nozzle (103) clamp the bag body (1) accordingly. The above-mentioned vibration positioning type flow filter bag detection system uses the following method for detection, as detailed below: The left end of the bag (1) is held by the upper left clamp (2) and the lower left clamp (4), and the right end of the bag (1) is held by the upper right clamp (6) and the lower right clamp (8), so that the entire bag (1) is kept in a taut, disc-shaped state. Then, an area to be tested is selected on the bag (1), and the area to be tested on the bag (1) is held by the individual detection unit (101) and the individual funnel (11). Then, the detection liquid is injected into all the detection units (101). After passing through the nozzle (103), the detection liquid permeates the bag (1) and falls into the corresponding funnel. (11) The liquid then flows into the measuring cylinder (13). At the same time, the handheld vibration mechanism (14) slightly vibrates the bag (1) near the part to be tested, accelerating the penetration rate of the test liquid. After a preset time, the flow rate of the test liquid in the four measuring cylinders (13) is recorded respectively. Then the flow rate is compared to determine whether there is any damage to the part to be tested and the specific damaged part. Subsequently, the funnel (10) is moved to continue testing the next area of ​​the bag and the corresponding flow rate is recorded until all bags are tested and all flow rates are recorded.
