Description

Technical Field

[0001] This utility model belongs to the technical field of industrial dust removal equipment, and in particular relates to a modular adjustable tube sheet device with dynamic sealing function. Background Technology

[0002] Baghouse dust collectors are highly efficient dust removal equipment widely used in industrial production, playing a crucial role in flue gas purification in industries such as steel, cement, chemical, and power. The tube sheet, as the core component of a baghouse dust collector, primarily functions to fix the filter bags and create effective isolation between the clean air chamber and the dust-laden air chamber, directly impacting the dust collector's operating efficiency and maintenance costs.

[0003] In related technologies, most baghouse dust collectors adopt an integral fixed tube sheet structure. A typical existing solution is an integral welded tube sheet with reinforcing ribs. This solution uses a 6-10 mm thick steel plate, with CNC punching creating evenly distributed filter bag mounting holes. Short pipes are welded to the edges of the holes to protect the filter bags and guide the cleaning airflow. The tube sheet is fixed to the dust collector housing frame by welding or high-strength bolts. To enhance rigidity and prevent deformation under pressure differential, grid-shaped or radial reinforcing ribs are welded to the back of the tube sheet. However, once the tube sheet is installed, its height and filter bag spacing are fixed and cannot be adjusted. It cannot be optimized according to changes in airflow volume, differences in dust characteristics, or different filter bag specifications. This makes it difficult for the dust collector to adapt to changing actual operating conditions. The uniformity of airflow distribution depends entirely on the initial design. If the actual operating conditions deviate from the design, it can easily lead to excessively high local airflow velocities, causing filter bag wear, or localized dead zones leading to dust accumulation. Furthermore, replacing damaged filter bags is extremely inconvenient, especially when replacing filter bags in the middle position. The operating space is limited, and it is often necessary to remove several intact filter bags around them first, resulting in high workload, long downtime, and high maintenance costs.

[0004] Therefore, how to achieve flexible adjustment of the tube sheet height and filter bag spacing, while maintaining reliable airtight isolation between the clean air chamber and the dust chamber during the adjustment process, in order to improve the working condition adaptability of baghouse dust collectors, simplify maintenance operations and optimize dust removal performance, is a key issue of concern to those skilled in the art.

[0005] To address the problems existing in the prior art, this utility model provides a modular adjustable tube sheet device with dynamic sealing function. This device can flexibly adjust the tube sheet height and filter bag spacing, and maintain reliable airtight isolation between the clean air chamber and the dust chamber during the adjustment process, thereby improving the working condition adaptability of the bag filter, simplifying maintenance operations and optimizing dust removal performance.

[0006] To achieve the purpose of this utility model, the following technical solution is adopted: a modular adjustable tube sheet device with dynamic sealing function, used in a bag filter to separate the clean air chamber and the dust chamber and fix the filter bag, comprising: An adjustable support frame is fixed to the dust collector housing, and the adjustable support frame includes a height adjustment mechanism; Multiple tube sheet modules are provided, each tube sheet module is disposed on the adjustable support frame, and each tube sheet module has at least one filter bag mounting hole. The tube sheet modules are connected by a spacing adjustment mechanism, which is used to adjust the spacing between adjacent tube sheet modules. A dynamic sealing assembly, comprising an inter-module sealing structure and an inter-module and housing sealing structure, wherein the inter-module sealing structure is disposed at the joint of adjacent tube sheet modules, and the inter-module and housing sealing structure is disposed at the joint of the tube sheet module and the inner wall of the dust collector housing. The height adjustment mechanism is used to adjust the overall height of the perforated plate module relative to the box body. The inter-module sealing structure maintains the airtightness between adjacent perforated plate modules during the process of the spacing adjustment mechanism adjusting the spacing of the perforated plate modules. The module-box sealing structure maintains the airtightness between the perforated plate module and the box body during the process of the height adjustment mechanism adjusting the height.

[0007] Optionally, the inter-module sealing structure includes multiple lip-shaped elastic sealing strips, which are disposed on the sides of adjacent tube sheet modules. Under the action of pre-tightening force, the lip-shaped elastic sealing strips remain tightly attached to the sides of adjacent tube sheet modules.

[0008] Optionally, the sealing structure between the module and the housing includes an inflatable sealing ring or a spring-compensated sealing strip, which adaptively compensates for displacement differences when the height of the tube sheet module changes.

[0009] Optionally, the spacing adjustment mechanism includes at least one of a guide rail, a lead screw, a gear rack, and a pin positioning structure, and the flower plate module achieves relative position adjustment and fixation through the spacing adjustment mechanism.

[0010] Optionally, the height adjustment mechanism includes at least one of an electric jack, a hydraulic cylinder, a scissor lift mechanism, and a chain wire rope synchronous lifting system. The height adjustment mechanism is connected to the adjustable support frame to achieve the overall lifting of the tube sheet module.

[0011] Optionally, the tube sheet module has a flip-up structure or a vibrating structure, which is used to actively remove accumulated dust.

[0012] Optionally, the shape and size of the tube sheet module are designed according to the position of the compartment partitions, the position of the reinforcing ribs, and the characteristics of the filter bag load distribution in the dust collector housing. The division of the tube sheet module avoids the main beam of the housing.

[0013] Optionally, a control unit is also included, which is electrically connected to the height adjustment mechanism and the spacing adjustment mechanism. The control unit is used to control the operation of the height adjustment mechanism and the spacing adjustment mechanism based on the operating data collected by the differential pressure sensor or the flow sensor.

[0014] Optionally, the control unit includes a programmable logic controller (PLC), which is used to automatically adjust the height and spacing of the perforated modules according to a preset algorithm to optimize airflow distribution.

[0015] Compared with the prior art, this utility model has the following advantages: By organically combining an adjustable support frame, tube sheet modules, and dynamic sealing components, this device achieves flexible adjustment of the tube sheet height and filter bag spacing, while maintaining reliable airtight isolation between the clean air chamber and the dust chamber throughout the adjustment process. Compared to traditional fixed tube sheet structures, this device can dynamically optimize airflow distribution according to actual operating conditions, effectively avoiding problems such as excessively high local filtration velocities or airflow dead zones caused by deviations between initial design and actual operation.

Detailed Implementation

[0017] To address the problems existing in the prior art, this utility model provides a modular adjustable tube sheet device with dynamic sealing function. This device can flexibly adjust the tube sheet height and filter bag spacing, and maintain reliable airtight isolation between the clean air chamber and the dust chamber during the adjustment process, thereby improving the working condition adaptability of the bag filter, simplifying maintenance operations and optimizing dust removal performance.

[0018] The technical solutions of the present utility model will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof: Please refer to Figure 1 , Figure 1 This is a front view of a modular adjustable perforated plate device with dynamic sealing function provided in an embodiment of this application.

[0019] Please refer to Figure 2 , Figure 2 This is a top view of a modular adjustable perforated plate device with dynamic sealing function provided in an embodiment of this application.

[0020] like Figure 1 As shown, this embodiment provides a modular adjustable tube sheet device with dynamic sealing function, applied to an HMC-96A medium-sized pulse bag filter. The device includes an adjustable support frame 1, multiple tube sheet modules 2, and a dynamic sealing assembly 3.

[0021] The adjustable support frame 1 is fixed to the inner wall of the dust collector housing 5. This frame is welded from I-beams and has sufficient rigidity to support the weight of the tube sheet module 2 and the filter bags. The adjustable support frame 1 includes a height adjustment mechanism 11, which employs an electric push rod structure. Specifically, it includes four electric push rods, each installed at one of the four corners of the adjustable support frame 1. The upper end of each electric push rod is fixedly connected to the crossbeam of the adjustable support frame 1, and the lower end is fixed to a support base at the bottom of the dust collector housing 5. By synchronously controlling the extension and retraction of the four electric push rods, the height of the tube sheet module 2 relative to the overall housing can be adjusted.

[0022] There are eight tube sheet modules 2 arranged in a rectangular array on the adjustable support frame 1. Each tube sheet module 2 is a rectangular steel plate, measuring 1200 mm × 800 mm and 8 mm thick, made of Q235 steel plate. Each tube sheet module 2 has 12 filter bag mounting holes 21 evenly spaced, with a hole diameter of 150 mm. A venturi tube with a height of 80 mm is welded to the edge of the hole for mounting filter bags with a diameter of 130 mm and a length of 2500 mm.

[0023] Adjacent perforated plate modules 2 are connected by a spacing adjustment mechanism 12. The spacing adjustment mechanism 12 employs a guide rail-slider combined with a lead screw drive structure. Specifically, a guide rail is provided on the adjustable support frame 1 along the arrangement direction of the perforated plate modules 2. A slider that cooperates with the guide rail is installed at the bottom of each perforated plate module 2, allowing the perforated plate module 2 to slide along the guide rail direction. A lead screw is provided between adjacent perforated plate modules 2, with its two ends threadedly connected to the two adjacent perforated plate modules 2 respectively. A handwheel is installed in the middle of the lead screw. Rotating the handwheel drives the lead screw to rotate, thereby moving adjacent perforated plate modules 2 closer or further apart, achieving spacing adjustment within a range of 50-150 mm.

[0024] The dynamic sealing assembly 3 includes an inter-module sealing structure 31 and an inter-module and housing sealing structure 32. The inter-module sealing structure 31 is located at the joint of adjacent tube sheet modules 2 and employs three silicone rubber lip-shaped elastic sealing strips, each 5 mm thick and 30 mm wide. The lip-shaped elastic sealing strips are bolted to the side of one tube sheet module 2, with the lips tightly adhering to the side of the adjacent tube sheet module 2 under pre-tightening force. When the spacing adjustment mechanism 12 adjusts the spacing of the tube sheet modules 2, the lip-shaped elastic sealing strips maintain close contact with the side of the adjacent tube sheet module 2 during sliding, ensuring airtightness at the joint and preventing dust-laden gas from leaking from the dust chamber to the clean air chamber.

[0025] The sealing structure 32 between the module and the housing is located at the joint between the outer edge of the tube sheet module 2 and the inner wall of the dust collector housing 5, and adopts an inflatable sealing ring. The inflatable sealing ring is a ring-shaped rubber air bladder, installed in the groove of the outer edge of the tube sheet module 2, and connected to the air source through an air pipe. Under normal working conditions, compressed air at a pressure of 0.2 MPa is injected into the sealing ring, causing it to expand and tightly fit against the inner wall of the housing, achieving effective sealing. When the height adjustment mechanism 11 adjusts the overall height of the tube sheet module 2, the inflatable sealing ring can adaptively compensate for the displacement difference caused by the height change, always maintaining sealed contact with the inner wall of the housing.

[0026] The operation of this embodiment can include: when the air volume handled by the dust collector increases, the operator can raise the entire tube sheet module 2 by 50 mm by controlling the electric push rod in the height adjustment mechanism 11, increasing the effective filtration length of the filter bags in the dust chamber to accommodate the increased air volume. Simultaneously, the spacing between adjacent tube sheet modules 2 is adjusted from the initial 100 mm to 120 mm by the spacing adjustment mechanism 12, increasing the space between the filter bags, improving airflow distribution, and reducing local filtration velocity. Throughout the adjustment process, the lip-shaped elastic sealing strip in the inter-module sealing structure 31 remains tightly attached to the side of the adjacent tube sheet module 2, and the inflatable sealing ring in the inter-module and housing sealing structure 32 adaptively compensates for displacement differences, ensuring reliable isolation between the clean air chamber and the dust chamber, and ensuring that the dust collector's emission concentration always meets environmental protection requirements.

[0027] In summary, this embodiment achieves flexible adjustment of the tube sheet height and filter bag spacing through the organic combination of an adjustable support frame, tube sheet module, and dynamic sealing assembly, while maintaining reliable airtight isolation between the clean air chamber and the dust chamber throughout the adjustment process. Compared to traditional fixed tube sheet structures, this device can dynamically optimize airflow distribution according to actual operating conditions, effectively avoiding problems such as excessively high local filtration velocities or airflow dead zones caused by deviations between initial design and actual operation. This significantly improves the dust collector's adaptability to different processing volumes, dust characteristics, and filter bag specifications. The modular design provides more operating space when replacing filter bags, allowing direct contact with the target filter bag without removing surrounding intact filter bags, greatly reducing maintenance workload and downtime. The innovative application of the dynamic sealing assembly ensures sealing reliability throughout the height and spacing adjustment process, preventing secondary pollution caused by dust-laden gas leakage, ensuring long-term stable operation and compliant emissions of the dust collector, and providing a practical technical solution for the intelligent and efficient development of industrial dust collection equipment.

[0028] Furthermore, this application also provides another specific embodiment.

[0029] This embodiment provides a modular adjustable tube sheet device for LCM176-6A type long bag low-pressure pulse dust collector. The main difference from the first embodiment lies in the specific structure of the height adjustment mechanism 11, the spacing adjustment mechanism 12, and the tube sheet module 2.

[0030] In this embodiment, the height adjustment mechanism 11 adopts a hydraulic cylinder structure. Specifically, hydraulic cylinders are installed at the four corners of the adjustable support frame 1, with the piston rods of the hydraulic cylinders connected to the crossbeams of the adjustable support frame 1, and the cylinder bodies fixed to the bottom of the dust collector housing 5. The hydraulic cylinders are supplied with oil through a hydraulic pump station, the output pressure of which is 10 MPa. The four hydraulic cylinders achieve synchronized operation through a synchronous flow divider valve, ensuring that the tube sheet module 2 rises and falls smoothly as a whole, with an adjustment range of 0-500 mm. Since the filter bag length of the LCM176-6A dust collector exceeds 6 meters, the use of hydraulic drive can provide greater load-bearing capacity and a smoother adjustment process.

[0031] The spacing adjustment mechanism 12 adopts a gear and rack transmission structure. Specifically, a rack is fixedly installed on the adjustable support frame 1 along the arrangement direction of the perforated plate modules 2. A gear that meshes with the rack is installed at the bottom of each perforated plate module 2, and the gear is connected to the perforated plate module 2 through a bearing seat. When spacing adjustment is required, the gear is driven to rotate by a motor, and the gear rolls along the rack, moving the perforated plate module 2. A linkage mechanism is set between adjacent perforated plate modules 2 to ensure coordinated overall movement during adjustment and avoid local stress concentration.

[0032] The shape and size of the tube sheet module 2 are specifically designed based on the structural characteristics of the LCM176-6A dust collector housing 5. Specifically, the dust collector housing 5 has longitudinal and transverse reinforcing ribs inside, dividing the housing into multiple areas. The division of the tube sheet module 2 fully considers the position of the reinforcing ribs; the edge of each module is aligned with the reinforcing rib, avoiding the main beam of the housing. This results in more uniform support for the tube sheet module 2 and effectively prevents shaking caused by tube sheet deformation during the operation of long filter bags. Each tube sheet module 2 measures 1500 mm × 1000 mm, with a total of 16 modules. Each module has 16 filter bag mounting holes 21, each with a diameter of 180 mm, for mounting long filter bags with a diameter of 160 mm and a length of 6500 mm.

[0033] In this embodiment, the inter-module sealing structure 31 still uses lip-shaped elastic sealing strips, but the number of sealing strips and the pre-tightening force are increased. Specifically, five lip-shaped elastic sealing strips are set, each made of fluororubber, which has better temperature resistance and can adapt to the working conditions of the LCM176-6A dust collector handling high-temperature flue gas. The inter-module and housing sealing structure 32 uses a spring-compensated sealing strip, which is composed of a stainless steel spring sheet and a rubber sealing layer. The spring sheet provides the restoring force, and the rubber layer achieves the sealing contact. When the height of the tube sheet module 2 changes, the elastic deformation of the spring sheet can compensate for the displacement difference and maintain the sealing pressure with the inner wall of the housing.

[0034] Furthermore, the tube sheet module 2 in this embodiment is also equipped with a flip-up structure. Specifically, each tube sheet module 2 is connected to the adjustable support frame 1 via a hinge, with the hinge axis parallel to the long side of the tube sheet module 2. During cleaning or maintenance, the tube sheet module 2 can be flipped upwards at a certain angle around the hinge axis using a hydraulic cylinder or electric push rod, allowing the accumulated dust on the tube sheet surface to slide off naturally, while also facilitating the inspection and replacement of the filter bag openings. During the flipping process, the inter-module sealing structure 31 and the module-to-box sealing structure 32 temporarily lose their sealing state, and the seal is re-established after the flipping and resetting.

[0035] This embodiment is particularly suitable for long bag dust collectors handling high-concentration, high-temperature dust-laden gases. Through hydraulically driven height adjustment and gear rack spacing adjustment, the tension and spacing of the filter bags can be precisely controlled, preventing excessive swaying of the filter bags during cleaning and extending their service life. The flip-over structure effectively solves the long-standing problem of dust accumulation on the tube sheet of long bag dust collectors.

[0036] Furthermore, this application also provides another specific embodiment.

[0037] This embodiment provides an intelligent modular adjustable tube sheet device for a PPC40-5A type air-box pulse bag filter. The dust collector includes 5 chambers, each with an independently configured tube sheet device. The main difference from the first embodiment and embodiment 2 is the addition of a control unit and sensor system, which enables automated adjustment.

[0038] In this embodiment, the height adjustment mechanism 11 employs a chain and wire rope synchronous lifting system. Specifically, lifting points are set at the four corners of the adjustable support frame 1 in each compartment, connected to an electric winch via wire ropes. The wire ropes achieve synchronous lifting through a fixed pulley system. The electric winch is driven by a three-phase asynchronous motor and equipped with a frequency converter for stepless speed regulation, ensuring smooth lifting. The chain is used for limiting and preventing wire rope slack, ensuring safety and reliability.

[0039] The spacing adjustment mechanism 12 employs a combination of a pin-positioning structure and a guide rail slider. Specifically, a guide rail is installed on the adjustable support frame 1, and a slider is mounted on the bottom of the perforated plate module 2, allowing the module to slide along the guide rail. A set of positioning holes is provided on the guide rail every 20 millimeters, and a pneumatic pin is installed on the bottom of the perforated plate module 2. When adjusting the spacing, the pneumatic pin is first retracted via the control system to release the positioning. Then, the operator or an automatic propulsion device moves the perforated plate module 2 to the target position, and the pin extends to insert into the positioning hole for precise positioning and locking. This structure offers high adjustment accuracy and reliable positioning, making it particularly suitable for applications requiring frequent adjustments.

[0040] The core innovation of this embodiment lies in the addition of a control unit and a sensor system. The control unit adopts a Siemens S7-1200 series programmable logic controller (PLC), which has analog input modules and digital input / output modules, and can acquire sensor signals and control the actions of actuators.

[0041] The sensor system may include: a differential pressure sensor installed between the clean air chamber and the dust chamber of each compartment, with a measurement range of 0-5 kPa, used to monitor the pressure difference across the filter bag; a flow sensor installed in the air inlet duct of each compartment, using a Pitot tube flow meter, to measure the actual processing air volume of the compartment; a temperature sensor installed on the surface of the tube sheet module 2 to monitor the flue gas temperature; and an emission concentration monitor installed outside the housing to monitor the dust concentration at the dust collector outlet in real time.

[0042] The PLC in the control unit executes a preset control algorithm based on the operating data collected by the sensors. Specific control logic may include: When the differential pressure sensor of a certain chamber detects that the differential pressure exceeds the set threshold (e.g., 2 kPa), it indicates that the filter bags in that chamber are severely dusty or the airflow distribution is uneven. The PLC controls the spacing adjustment mechanism 12 of that chamber to appropriately increase the spacing between adjacent tube sheet modules 2, reduce the local filtration velocity, and bring the differential pressure back to the normal range.

[0043] The PLC collects data from the flow sensors in each chamber in real time and calculates the deviation of the air volume in each chamber. When the air volume of a certain chamber deviates from the average value by more than 15%, the PLC controls the height adjustment mechanism 11 of that chamber to fine-tune the height of the tube sheet, change the resistance characteristics of that chamber, and make the air volume of each chamber tend to be balanced, thus solving the problem of uneven air volume distribution caused by differences in pipe resistance.

[0044] When the temperature sensor detects that the flue gas temperature exceeds the upper limit of the filter bag's temperature resistance (e.g., 260 degrees Celsius), the PLC immediately triggers an alarm and can link with the control system to reduce the processing air volume of the chamber to prevent the filter bag from burning.

[0045] Based on data from the emission concentration monitor, combined with pressure difference and air volume information, the PLC optimizes the height and spacing combination of the tube sheet module 2 through a self-learning algorithm to find the optimal operating condition point with the lowest pressure difference (i.e., the lowest operating energy consumption) while meeting emission standards.

[0046] The control unit also features a human-machine interface, employing a 7-inch touchscreen mounted on the dust collector control cabinet panel. Operators can view real-time operating parameters and historical curves for each compartment via the touchscreen, manually adjust the tube sheet height and spacing, set automatic control parameters, and query fault records. The control unit also has a reserved communication interface supporting the Modbus RTU protocol, allowing it to connect to the enterprise's DCS system or remote monitoring platform for data upload and remote control.

[0047] This embodiment is particularly suitable for applications where airflow and dust concentration fluctuate significantly and emission requirements are stringent. Through the automatic adjustment of the intelligent control system, the dust collector always operates at its optimal condition, ensuring compliance with emission standards while reducing energy consumption and minimizing manual intervention. This demonstrates the technological advancement and economic benefits of the device in practical applications.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
