Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas environmental protection treatment device. Background Technology

[0002] Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before its external emission to meet emission standards.

Filter element replacement requires shutdown and disassembly of the housing, affecting continuous production and causing maintenance difficulties; 3. Thermal deformation between the rotating shaft and the housing under high-temperature conditions causes dust leakage and seal failure. Utility Model Content

[0004] This utility model discloses an environmentally friendly waste gas treatment device. It studies and improves the existing structure and its shortcomings, and provides an environmentally friendly waste gas treatment device to achieve better practical value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas environmental protection treatment device, comprising:

[0007] The partitioned box is a vertically arranged annular cavity. Its inner cavity is divided into independent processing chambers by multiple radial partitions along the circumference. The outer ends of each radial partition are fixedly connected to the inner wall of the partitioned box, and a sealed gap is formed between the inner end and the central rotating shaft.

[0008] The central rotating shaft runs coaxially through the central holes at the top and bottom of the partitioned housing, and is connected to the drive motor at the top.

[0009] A rotating support is connected to the center of the rotating shaft, and its cantilever structure extends radially to each independent processing chamber;

[0010] Modular filter units, the number of which corresponds to the number of independent processing chambers, with each modular filter unit suspended at the end of the cantilever structure of the rotating bracket;

[0011] The air intake pipe is located at the bottom of the partitioned enclosure.

[0012] Backflush assembly is located at the top of the partitioned enclosure;

[0013] The dust collection mechanism is located at the bottom of the partitioned box.

[0014] The flow guiding structure is coaxially fixed to the middle of the central rotating shaft, and its conical surface covers the inner end face of the radial partition, forming a radial sealing gap between the two.

[0015] A height difference is reserved between the top of the partitioned housing and the modular filter unit, forming a channel for the modular filter unit to rotate.

[0016] In some embodiments, the modular filter unit includes a conical chamber, a mesh plate, a quick-release latch, and a vertical slot;

[0017] The grid plate is installed at the bottom of the conical chamber; the quick-release latch is hinged to the upper edges of both sides of the conical chamber; the vertical slot is opened in the inner wall of the conical chamber; and the swirl guide vane is connected below the grid plate.

[0018] In some embodiments, the backflush assembly includes an annular air supply pipe, a telescopic nozzle, a sealing cover, and a lifting cylinder;

[0019] The annular air supply pipe is connected to the top of the partitioned housing; the telescopic nozzle is connected to the lower end of the annular air supply pipe; the sealing cover is connected to the end of the telescopic nozzle; the lifting cylinder is installed on the top of the partitioned housing, and its piston rod is hinged to the telescopic nozzle.

[0020] In some embodiments, the top of the flow guiding structure is provided with a sealing flange; the top of the partitioned box is provided with an annular sealing groove, the groove being filled with high-temperature graphite packing; the sealing flange is embedded in the annular sealing groove.

[0021] In some embodiments, the annular sealing groove sidewall is provided with a cooling medium channel; the inlet of the cooling medium channel is connected to a cold source interface.

[0022] In some embodiments, the sealing cover is provided with a porous pressure equalizing plate; the porous pressure equalizing plate is provided with an array of conical spray holes, the large diameter end of which faces the modular filter element unit.

[0023] In some embodiments, the dust collection mechanism includes a dust collection disc, a concentric annular scraper, a connecting rod, an eccentric slag discharge port, and a corrugated compensator;

[0024] The concentric annular scraper is connected to the bottom of the central rotating shaft via a connecting rod; the eccentric slag discharge port is located at the lowest point of the dust collection pan side wall; the corrugated compensator connects the dust collection pan to the partitioned box, and has embedded corrosion-resistant spring steel sheets; the dust collection pan side wall is equipped with a dust accumulation alarm.

[0025] In some embodiments, the rotating bracket includes a cantilever structure, a locking groove, and an elastic top ball; a weight sensor is provided inside the cantilever structure; the locking groove is located on the lower surface of the cantilever structure.

[0026] The elastic top bead is located on the side wall of the lock groove.

[0027] In some embodiments, the partitioned enclosure sidewall hinged maintenance structure is positioned corresponding to the stationary position of the rotating bracket; the maintenance structure includes a pressure-resistant observation window embedded in the partitioned enclosure sidewall.

[0028] The waste gas environmental protection treatment equipment provided by this utility model has the following advantages:

[0029] 1. Achieve continuous operation: The modular filter unit is driven to rotate periodically by the rotating bracket, so that each independent treatment chamber enters the working area in sequence. When a specific filter chamber needs maintenance, the system automatically moves it out of the working area, so that the entire process of exhaust gas treatment can be carried out without stopping the machine.

[0030] 2. Eliminate sealing leakage: The flow guiding structure covers the inner end of the radial partition to form a radial sealing gap. At the same time, the high-temperature graphite packing in the annular sealing groove compensates for the thermal deformation effect, which together block the airflow channel between the central rotating shaft and the partition, effectively preventing dust from escaping and air leakage in the chamber.

[0031] 3. Improve maintenance efficiency: The quick-release latch allows for rapid disconnection of the modular filter unit from the cantilever structure, and the vertical guide structure of the vertical slot allows the filter compartment to be pulled out by hand, greatly simplifying the replacement process.

[0032] 4. Reduce filter element load: The swirl guide vanes induce centrifugal motion in the exhaust gas below the grid plate, achieving pre-separation of large dust particles and guiding them to the dust collection mechanism, significantly reducing the total amount of dust entering the filter element.

[0033] 5. Ensure uniform dust removal: The lifting cylinder drives the sealing cover to tightly press the top of the filter cartridge compartment, so that the conical nozzles of the multi-hole pressure equalizing plate spray evenly distributed airflow onto the surface of the filter cartridge, completely eliminating dust removal dead corners.

[0034] 6. Proactive fault warning: Based on the weight sensor inside the cantilever structure, the filter element weight change is monitored in real time, and the replacement command is triggered in time; at the same time, the dust accumulation alarm on the side wall of the dust collection tray detects the dust accumulation status and links to control the eccentric slag discharge port to automatically discharge slag.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0045] Reference Figures 1 to 8 In a preferred embodiment, an environmentally friendly waste gas treatment device includes a partitioned housing 1, a central rotating shaft 2, a rotating support, a modular filter element unit 4, an air inlet pipe 5, a backflushing assembly, a dust collection mechanism, and a flow guiding structure 15.

[0046] like Figures 1 to 4 As shown, the partitioned housing 1 is a vertically arranged annular cavity. Its inner cavity is divided into independent processing chambers 12 by multiple radial partitions 11 evenly along the circumference. Each independent processing chamber 12 is an axially extending fan-shaped cylindrical space. The outer ends of each radial partition 11 are fixedly connected to the inner wall of the partitioned housing 1, and the inner ends form a 5-8mm annular sealing gap with the central rotating shaft 2. The central rotating shaft 2 coaxially passes through the central holes at the top and bottom of the partitioned housing 1, and the top is connected to the drive motor 21, which is supported by the dust collection disc 71 through a thrust bearing. The rotating bracket is connected to the middle of the central rotating shaft 2, and its cantilever structure 31 extends radially to each independent processing chamber 12. The number of cantilever structures 31 is the same as the number of independent processing chambers 12. The number of modular filter elements 4 corresponds to the number of independent processing chambers 12, and each modular filter element 4 is suspended from the end of the cantilever structure 31 of the rotating bracket. The air inlet pipe 5 is located at the bottom of the partitioned housing 1. The backflushing assembly is located at the top of the partitioned housing 1. The dust collection mechanism is located at the bottom of the partitioned housing 1. The flow guiding structure 15 is coaxially fixed to the middle of the central rotating shaft 2, and its conical surface covers the inner end face of the radial partition 11, forming a radial sealing gap between the two. A height difference is reserved between the top of the partitioned housing 1 and the modular filter element unit 4 to form a channel for the rotation of the modular filter element unit 4.

[0047] Specifically, such as Figure 2 and Figure 3 As shown, when the radial partition 11 comprises four pieces, the four radial partitions 11 extend vertically along 90° equally spaced angles with the central rotation axis 2 as the origin, forming a cross-shaped partition. Each independent processing chamber 12 is a 90° fan-shaped cylindrical space extending from the bottom to the top of the box. The rotating support simultaneously adopts a cross-shaped cantilever structure 31, with one modular filter element unit 4 suspended at each of the four ends. The conical surface of the flow guiding structure 15 can completely cover the inner ends of the four partitions. The corresponding cantilever structure 31 comprises four arms, which are welded to the central rotation axis 2 at 90° intersections. The center line of each modular filter element unit 4 chamber coincides with the axis of the cantilever structure 31, directly facing the center of the fan-shaped space of the chamber. The rotation of the central rotating shaft 2 enables station switching, driving all modular filter units 4 to synchronously move into adjacent independent processing chambers 12. When a modular filter unit 4 rotates from chamber A to chamber B, its functional mode switches according to the preset station of the chamber. The station includes a filtration station, a backflushing station, and a maintenance station. The outer end of the radial baffle 11 is connected to the partitioned housing 1, and the inner end is always covered by the conical surface of the flow guiding structure 15. The flow guiding structure 15 is a flow guiding cone. When the flow guiding structure 15 rotates with the shaft, its conical surface maintains a constant radial gap with the inner end of the baffle. In some other embodiments, the number of radial baffles 11 is greater than 4, and correspondingly, the number of modular filter units 4 and cantilever structures 31 is greater than 4 per unit.

[0048] Specifically, the intake pipe 5 is horizontally welded to the lowest point of the bottom side wall of the partitioned housing 1, with its axis at a 15° angle to the horizontal plane. This is used to maintain an exhaust gas velocity ≥18m / s to completely prevent dust accumulation in the pipe. The center of the pipe opening is directly aligned with the center of the swirl guide vane 46 of the modular filter element unit 4. The exhaust gas vertically impacts the working surface of the guide vane, thereby inducing a strong centrifugal swirling flow. The inlet section of the intake pipe 5 is trumpet-shaped, the main body is a straight pipe of equal diameter, and the outlet section is a tapered pipe (cone angle 30°). The outlet flange of the intake pipe 5 is bolted to the side wall interface of the partitioned housing 1, with a high-temperature resistant graphite gasket sandwiched between them. The inlet flange of the intake pipe 5 is connected to the exhaust gas source pipe, and a temperature measuring hole is drilled on the flange face.

[0049] In some embodiments, it also includes a cantilever support beam, the two ends of which are connected to the outer wall of the box 1 and the outer end of the radial partition 11; the rotating bracket includes a cantilever structure 31, a locking groove 32 and an elastic top bead 33; the cantilever structure 31 includes 4 cantilever structures, the 4 cantilever structures 31 are connected to the middle of the central rotating shaft 2 in a cross-shaped frame, and a weight sensor 311 is provided inside the cantilever structure 31; the locking groove 32 is provided on the lower surface of the cantilever structure 31; the elastic top bead 33 is provided on the side wall of the locking groove 32.

[0050] like Figure 3 and Figure 5 As shown, in some embodiments, the modular filter element unit 4 is vertically suspended at the end of the cantilever structure 31 of the rotating bracket and is completely housed within the independent processing chamber 12. The modular filter element unit 4 includes a conical chamber 41, a mesh plate 42, a quick-release latch 43, and a vertical slot 44; the mesh plate 42 is bolted to the bottom of the conical chamber 41; the quick-release latch 43 is hinged to the upper edges of both sides of the conical chamber 41; the vertical slot 44 is formed in the inner wall of the conical chamber 41; a swirl guide vane 46 is connected below the mesh plate 42, the vane 46 has a blade inclination angle of 45°, and the swirl guide vane 46 is used to induce the centrifugal rotation of the exhaust gas, causing large dust particles to collide with the wall and fall to the dust collection mechanism, reducing the dust load on the filter element surface by more than 40%. The modular filter element unit 4 also includes a plate filter element, which is vertically inserted along the vertical slot 44. Specifically, the conical chamber 41 has a cross-section that is narrower at the top and wider at the bottom (cone angle 60°), which guides airflow to converge towards the center of the filter element. A rectangular hanging lug is located at its top. The mesh plate 42 is a circular perforated steel plate, designed to ensure even airflow penetration and work in conjunction with the conical chamber 41 to improve filtration efficiency. The vertical slot 44 consists of symmetrical T-shaped grooves on the inner wall of the conical chamber 41. The rectangular hanging lug engages with the locking groove 32 of the cantilever structure 31. The quick-release latch 43 rotates 90° to lock the rectangular hanging lug, and the elastic top bead 33 pops out for positioning, suppressing rotational vibration. After unlocking the quick-release latch 43, the chamber is pulled down by hand, and the plate filter element is vertically removed along with the vertical slot 44, facilitating quick filter element replacement.

[0051] like Figure 6As shown, in some embodiments, the backflushing assembly includes an annular air supply pipe 61, a telescopic nozzle 62, a sealing cover 63, and a lifting cylinder 64. The annular air supply pipe 61 is an annular seamless steel pipe connected to the top of the partitioned housing 1. The telescopic nozzle 62 has a double-layer sleeve structure, connecting to the lower end of the annular air supply pipe 61 and extending vertically downwards to above the modular filter element unit 4. The sealing cover 63 is a bowl-shaped stainless steel cover connected to the end of the telescopic nozzle 62. The lifting cylinder 64 is installed on the top of the partitioned housing 1, with its piston rod hinged to the upper section of the telescopic nozzle 62, and the cylinder body bolted to the top support of the partitioned housing 1. In some embodiments, the sealing cover 63 contains a porous pressure equalizing plate 631, which is a circular cobalt-based alloy plate. The porous pressure equalizing plate 631 has an array of conical nozzles 632, with the large-diameter end facing the modular filter element unit 4. The lifting cylinder 64 presses down the sealing cover 63 to fit tightly against the top surface of the modular filter element unit 4. The sealing lip of the sealing cover 63 deforms to fill the interface gap, thereby preventing the leakage of back-blowing airflow. Compressed air diffuses through the conical nozzle 632, with the large-diameter end facing the filter element surface to form an umbrella-shaped flow field, covering 100% of the effective area of ​​the filter element. The telescopic nozzle 62 compensates for the rotational positioning error of the rotating bracket, and the sealing cover 63 is always directly facing the center of the modular filter element unit 4, improving the dust removal efficiency.

[0052] like Figure 8 As shown, in some embodiments, the top of the flow guiding structure 15 is provided with a sealing flange; the top of the partitioned box 1 is provided with an annular sealing groove 18, and the groove is filled with high-temperature graphite packing 181; the sealing flange is embedded in the annular sealing groove 18.

[0053] In some embodiments, the annular sealing groove 18 has a cooling medium channel 182 on its side wall; the inlet of the cooling medium channel 182 is connected to a cold source interface.

[0054] like Figure 7 As shown, in some embodiments, the dust collection mechanism is coaxially located directly below the partitioned box 1. The dust collection mechanism includes a shallow conical dust collection disc 71, a concentric annular scraper 72, a connecting rod 73, an eccentric slag discharge port 74, and a corrugated compensator 75; the bottom of the dust collection disc 71 is inclined toward the eccentric slag discharge port 74.

[0055] The concentric annular scraper 72 consists of three equally high serrated steel rings welded together by spokes. The concentric annular scraper 72 is connected to the bottom of the central rotating shaft 2 via a connecting rod 73. The central rotating shaft 2 drives the scraper 72 to rotate. The serrated rings of the concentric annular scraper 72 push dust towards the eccentric slag discharge port 74, improving slag removal efficiency. Furthermore, the serrations of the concentric annular scraper 72 periodically agitate the dust layer, breaking the dust chain structure and completely eliminating bridging. The eccentric slag discharge port 74 is located at the lowest point of the side wall of the dust collection pan 71. The corrugated compensator 75 is a multi-layered stainless steel corrugated structure. The corrugated compensator 75 connects the dust collection pan 71 to the partitioned housing 1, and has embedded corrosion-resistant spring steel sheets 751. This corrugated compensator 75 absorbs the thermal expansion displacement of the partitioned housing, and the spring steel sheets 751 maintain a constant sealing pressure to prevent dust leakage. The dust accumulation alarm 76 is a radio frequency admittance level switch with a probe extending into the pan. A dust accumulation alarm 76 is installed on the side wall of the dust collection tray 71. When the dust accumulation alarm 76 detects that the accumulation height is greater than 80%, it will activate the pneumatic valve of the eccentric slag discharge port 74 to open, thus enabling unattended operation.

[0056] In some embodiments, the partitioned enclosure 1 has a maintenance structure hinged to its side wall, the position of which corresponds to the stationary position of the rotating bracket; the maintenance structure includes a pressure-resistant observation window 14 embedded in the side wall of the partitioned enclosure 1.

[0057] Each independent processing chamber 12 is completely isolated from other chambers. During normal filtration, exhaust gas enters through the inlet pipe 5, rises through the current filter element, and finally, purified gas is discharged from the top of the partitioned housing 1, effectively preventing untreated exhaust gas from entering the purification area. During backflushing, compressed air is injected into the target module filter element unit 4 through the sealing cover 63, and the dust falls to the dust collection tray 71, thus preventing the cleaning airflow from interfering with the filtration of adjacent chambers. When replacing the filter element, the target chamber is rotated to the maintenance position, the window is opened, and the modular filter element unit 4 is disassembled, ensuring the continuous operation of other chambers.

[0058] Working principle:

[0059] Before operation: Insert the filter element into the vertical slot 44 of the modular filter element unit 4; lock the cantilever structure 31 with the quick-release latch 43.

[0060] During operation: exhaust gas rises from the inlet pipe 5 and undergoes centrifugal pre-separation treatment via the swirl guide vane 46, then passes through the filter element on the vertical slot 44 of the modular filter element unit 4; the drive motor 21 is started, driving the rotating bracket to rotate; when the back-blowing component is started on a timed basis, the lifting cylinder 64 presses down the sealing cover 63 to fit tightly against the modular filter element unit 4, and the pulse airflow cleans the dust through the conical spray hole 632; the concentric annular scraper 72 pushes the dust in the dust collection disc 71 to the eccentric slag discharge port 74.

[0061] After work: After the weight sensor 311 alarms, rotate the rotating bracket to align the target compartment with the maintenance structure, open the quick-release latch 43 to replace the filter element.

[0062] Any content not described in detail in this specification is prior art known to those skilled in the art.

[0063] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
