Description

Technical Field

[0001] This invention belongs to the field of industrial waste gas treatment technology, specifically referring to a bag filter dust collector for industrial waste gas treatment. Background Technology

[0002] Baghouse dust collectors are widely used in industrial waste gas treatment in industries such as thermal power, steel, and cement due to their high dust removal efficiency and relatively low operating costs. However, traditional baghouse dust collectors still face some technical challenges in practical applications.

[0003] First, during the filtration process, dust-laden exhaust gas typically enters the dust collector housing from one or more fixed directions, causing the windward side of the filter bags to bear a high filtration load and dust impact for a long time, while the leeward side is under a lighter load. This uneven air intake pattern can cause localized increased wear on the filter bags, significantly shortening their service life. Second, in the dust removal process, especially when using pulse jet cleaning, dust shaken off the surface of the filter bags is easily re-raised by the continuous airflow inside the housing and adheres to adjacent filter bags, causing "secondary dust" or "cross-contamination" problems. This not only reduces cleaning efficiency but also increases system resistance, affecting the stability of dust removal performance. In addition, for highly viscous dust, pulse jet cleaning alone is sometimes insufficient for complete removal, easily forming caking on the surface of the filter bags, limiting the effectiveness of conventional pulse jet cleaning methods. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a bag filter for industrial waste gas treatment, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a baghouse dust collector for industrial waste gas treatment, comprising: The housing has a dust collection hopper at the bottom and an exhaust box at the top; An air inlet pipe, located on the side of the enclosure, is used to input industrial waste gas into the enclosure. The exhaust pipe, located on the side of the exhaust box, is used to discharge the filtered gas. Multiple dust collector bags are evenly spaced inside the box. The upper part of the dust collector bags is located inside the exhaust box, and an exhaust groove is opened on the part of the dust collector bags located inside the exhaust box. Multiple pulse jet pipes are corresponding one-to-one with the dust collector bags, and the lower end of each pulse jet pipe extends into the dust collector bag. Multiple isolation cylinders are coaxially sleeved on the outside of the dust collector bag to isolate the dust collector bag; Multiple airflow channels are arranged in parallel inside the box and connected to the air inlet pipe. The airflow channels are connected to the isolation cylinder through the air inlet groove. The cleaning brush is configured to slide and rise in accordance with the inner wall of the isolation cylinder; A drive box is located on top of the exhaust box. The drive box contains a first power mechanism and a second power mechanism. The first power mechanism and the second power mechanism are two independent power sources. The dust collector bag is configured to rotate around its axis inside the isolation cylinder. The rotational power of the dust collector bag comes from the first power mechanism or the second power mechanism. The first power mechanism extends to the airflow channel, and its power source is the airflow generated when industrial waste gas enters. The airflow acts on the dust collector bag through the first power mechanism and drives it to rotate. The second power mechanism is connected to the cleaning brush, and the rotation of the dust collector bag and the lifting and lowering of the cleaning brush form a one-way linkage relationship: the rotation of the dust collector bag cannot drive the cleaning brush to lift and slide, but the lifting and sliding of the cleaning brush can drive the rotation of the dust collector bag in a linkage.

[0006] Furthermore, a pulse jet mechanism is provided outside the drive box, and the pulse jet pipe is connected to the pulse jet mechanism.

[0007] Furthermore, the first power mechanism includes multiple power shafts, the upper end of which is rotatably disposed in the drive box, and the lower end extends into the airflow channel. One end of the power shaft located in the airflow channel is provided with blades. The upper end of the power shaft is connected to an adjacent dust collector bag and to two adjacent dust collector bags via a drive belt.

[0008] Furthermore, the second power mechanism includes multiple sets of drive shafts and one set of driven shafts. Both the drive shafts and driven shafts are rotatably mounted on the side wall of the drive housing. A drive motor is mounted on the outer wall of the drive housing. One end of one set of drive shafts is connected to the output end of the drive motor, and the set of drive shafts is equipped with an incomplete gear. The driven shaft is equipped with a complete gear. The incomplete gear meshes with the complete gear intermittently. Adjacent sets of drive shafts are connected by a belt or chain drive. The rotation of the drive shafts drives the cleaning brush to slide and rise against the inner wall of the isolation cylinder. The rotation of the driven shafts drives the dust collector bag to rotate.

[0009] Furthermore, each set of drive shafts is equipped with multiple rope reels, on which lifting ropes are wound, and the lifting ropes are connected to the cleaning brush.

[0010] Furthermore, the driven shaft is located on one side of the dust collector bag, the axis of the driven shaft is perpendicular to the axis of the dust collector bag, a worm is provided on the driven shaft, and a worm wheel is provided on the dust collector bag near the driven shaft, and the worm wheel meshes with the worm for transmission.

[0011] Furthermore, a sealing spring is provided on the side wall of the airflow channel away from the air inlet slot. The free end of the sealing spring extends through the air inlet slot into the isolation cylinder, and a sealing plate is connected to this end. The sealing plate is configured to be driven by the airflow of the intake and exhaust gases to move radially toward the axis of the isolation cylinder to seal the air inlet slot. In the initial state, under the action of the sealing spring, the outer wall of the sealing plate is in contact with the inner wall of the isolation cylinder, and in this state, the inner wall of the cleaning brush can be in contact with the inner wall of the sealing plate and the inner wall of the isolation cylinder.

[0012] Furthermore, the isolation cylinder is a closed cylinder with an opening at the lower end, and the air inlet groove is opened along the axial direction of the isolation cylinder. The upper end of the air inlet groove does not extend to the uppermost end of the isolation cylinder. In the initial state, the cleaning brush is stored in the position of the isolation cylinder where the air inlet groove is not opened.

[0013] Furthermore, the isolation cylinder has inclined surfaces on both sides of the air inlet slot, and the inclined surfaces are inclined toward one side of the air inlet slot.

[0014] Furthermore, the airflow channels are provided in multiple sets within the housing, each set of airflow channels corresponding to multiple sets of isolation cylinders and connected through an air inlet slot.

[0015] The technical solution provided by this invention has the following beneficial effects: (1) Two independent first power mechanism and second power mechanism are used as the driving source for the rotation of the dust collector bag, which ensures that the dust collector bag can achieve uniform load under all working conditions such as air intake filtration and pulse cleaning, solves the problem of wear on the windward side and blockage on the leeward side of the traditional bag, and extends the service life of the dust collector bag.

[0016] (2) By coaxially sleeved with an isolation cylinder on the outside of the dust collector bag, the dust blown off during pulse jet cleaning is physically isolated. At the same time, the cleaning brush that slides up and down against the inner wall of the isolation cylinder can thoroughly remove the dust adhering to the inner wall of the isolation cylinder, preventing the residual dust from being re-adsorbed onto the corresponding dust collector bag during subsequent air intake filtration.

[0017] (3) The second power mechanism realizes the one-way linkage between the lifting of the cleaning brush and the rotation of the dust collector bag. While the pulse jet cleaning is being carried out, the cleaning brush simultaneously brushes the inner wall of the isolation cylinder and drives the dust collector bag to rotate. This allows the pulse jet airflow to cover the entire circumferential surface of the dust collector bag, eliminating cleaning dead angles and realizing a three-dimensional deep cleaning that integrates jet cleaning, rotation, and brushing. This is especially suitable for removing highly viscous dust, preventing dust from caking on the surface of the bag and further improving cleaning efficiency. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0022] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0023] See Figure 1 and Figure 2 In this embodiment, the present invention provides a bag filter for industrial waste gas treatment, including a housing 1, an inlet pipe 4, and an exhaust pipe 5; the bottom of the housing 1 is provided with a dust collection hopper 2, and the top is provided with an exhaust box 3; the inlet pipe 4 is provided on the side of the housing 1 for inputting industrial waste gas into the housing 1; the exhaust pipe 5 is provided on the side of the exhaust box 3 for discharging the filtered gas.

[0024] See Figure 3 , Figure 4 and Figure 6 In this embodiment, the present invention provides a baghouse dust collector for industrial waste gas treatment, which further includes multiple dust collection bags 6, pulse jet pipes 8, isolation cylinders 9, and airflow channels 10; the multiple dust collection bags 6 are evenly spaced inside the housing 1, with the upper part of the dust collection bags 6 located inside the exhaust box 3, and an exhaust groove 7 is opened on the part of the dust collection bags 6 located inside the exhaust box 3, through which the filtered waste gas enters the exhaust box 3; multiple pulse jet pipes 8 correspond one-to-one with the dust collection bags 6, and the lower end of the pulse jet pipe 8 extends into the dust collection bag 6 to achieve dust removal. The dust collector bag 6 is cleaned by a comprehensive jet cleaning process on its inner wall. Multiple isolation cylinders 9 are coaxially sleeved on the outside of the dust collector bag 6 to isolate the dust collector bag 6 and prevent the dust blown off by the pulse jet pipe 8 during cleaning from causing secondary cross-contamination to adjacent dust collector bags 6. Multiple airflow channels 10 are arranged in parallel inside the housing 1 and connected to the air inlet pipe 4. The airflow channels 10 and the isolation cylinders 9 are connected by the air inlet groove 25. Industrial waste gas enters the isolation cylinder 9 through the air inlet pipe 4, the airflow channels 10, and the air inlet groove 25, and is filtered and dusted by the dust collector bag 6 inside the isolation cylinder 9.

[0025] See Figure 2 , Figure 8 and Figure 9In this embodiment, the present invention provides a bag filter for industrial waste gas treatment, which further includes a cleaning brush 11 and a drive box 12. The cleaning brush 11 is configured to slide up and down against the inner wall of the isolation cylinder 9. The inner wall of the isolation cylinder 9 is cleaned by the up and down sliding of the cleaning brush 11, so as to prevent the dust blown off by the pulse jet pipe 8 from adhering to the inner wall of the isolation cylinder 9 and being re-adsorbed onto the corresponding dust collector bag 6 during subsequent air intake filtration. The isolation cylinder 9 physically isolates the dust during cleaning, and the cleaning brush 11 removes the residue on the inner wall of the isolation cylinder 9, thus structurally preventing the cross-adsorption of dust during the cleaning period. The drive box 12 is located on the top of the exhaust box 3. The drive box 12 is equipped with a first power mechanism and a second power mechanism. The first power mechanism and the second power mechanism are two independent power sources. The dust collector bag 6 is configured to rotate around its axis inside the isolation cylinder 9. The rotation power of the dust collector bag 6 comes from the first power mechanism or the second power mechanism.

[0026] The first power mechanism extends to the airflow channel 10. Its power source is the airflow generated when industrial waste gas enters the air. The airflow acts on the dust collector bag 6 through the first power mechanism and drives it to rotate. Under the drive of the first power source, different circumferential surfaces of the dust collector bag 6 can alternately correspond to the air inlet slot 25. This means that the dust-laden waste gas no longer continuously impacts a fixed windward surface of the bag, but is evenly distributed on the entire circumferential surface of the bag as the bag rotates. This fundamentally changes the problem of excessive local filtration load caused by fixed air in traditional bag dust collectors, realizes the circumferential uniform distribution of filtration load, avoids premature damage to the bag due to local dust impact and wear, and thus significantly extends the service life of the filter bag.

[0027] The second power mechanism is connected to the cleaning brush 11. The rotation of the dust collector bag 6 and the lifting of the cleaning brush 11 form a one-way linkage relationship: the rotation of the dust collector bag 6 cannot drive the cleaning brush 11 to lift and slide, but the lifting and sliding of the cleaning brush 11 can drive the dust collector bag 6 to rotate. Through the linkage between the lifting of the cleaning brush 11 and the rotation of the dust collector bag 6, there is no need to set a separate drive source for the intermittent rotation of the bag, which simplifies the structure and reduces costs and failure rates. While pulse jet blowing, the cleaning brush 11 scrapes the dust accumulated on the inner wall of the isolation cylinder 9 to cut off the internal secondary pollution chain, and its lifting action drives the bag to rotate, so that the pulse airflow can act on the entire circumference of the bag, eliminating the dead corners of dust removal and realizing a three-dimensional deep dust removal that integrates "jetting, rotation and brushing".

[0028] The first and second power mechanisms work together to drive the dust collector bag 6 to rotate, ensuring that the dust collector bag 6 is under uniform load under all working conditions. This completely solves the industry pain point of wear on the "windward side" and blockage on the "leeward side" of traditional bags, while keeping the air intake channel clean, thereby significantly extending the filter bag life and ensuring long-term stability of filtration efficiency and operating resistance.

[0029] See Figure 1 and Figure 5 In this embodiment, a pulse jet mechanism 13 is provided outside the drive box 12. The pulse jet pipe 8 is connected to the pulse jet mechanism 13. The pulse jet mechanism 13 is existing technology, and its specific structure, working principle and control method will not be described in detail here.

[0030] It is understood that the dust collector bag 6 used in this embodiment includes a bag body and a frame. The dust collector bag 6 is rotatably installed in the housing 1 and the exhaust box 3 through the frame. The bag body is covered on the outer periphery of the frame. Rotational support components (such as bearings and bushings) are provided at the rotational connection between the frame and the housing 1 and the exhaust box 3 to ensure that the dust collector bag 6 rotates smoothly and without jamming.

[0031] See Figure 3 and Figure 5 In this embodiment, the first power mechanism includes multiple power shafts 14. The upper end of the power shaft 14 is rotatably disposed in the drive box 12, and the lower end extends into the airflow channel 10. One end of the power shaft 14 located in the airflow channel 10 is provided with blades 15. The upper end of the power shaft 14 is connected to an adjacent dust collector bag 6 and to two adjacent dust collector bags 6 via a drive belt. When the exhaust gas flows into the box 1 through the airflow channel 10, it acts on the blades 15. The blades 15 drive the power shaft 14 to rotate. Through the drive belt, multiple dust collector bags 6 rotate synchronously.

[0032] See Figure 5 and Figure 7 In this embodiment, the second power mechanism includes multiple sets of drive shafts 16 and a set of driven shafts 17. Both drive shafts 16 and driven shafts 17 are rotatably mounted on the side wall of the drive housing 12. A drive motor 18 is mounted on the outer wall of the drive housing 12. One end of one set of drive shafts 16 is connected to the output end of the drive motor 18, and this set of drive shafts 16 is equipped with an incomplete gear 19. The driven shaft 17 is equipped with a complete gear 20. The incomplete gear 19 intermittently meshes with the complete gear 20. Adjacent sets of drive shafts 16 are connected by a belt or... The chain drive connects the drive shaft 16, which rotates to drive the cleaning brush 11 to slide and rise against the inner wall of the isolation cylinder 9. The driven shaft 17 rotates to drive the dust collector bag 6 to rotate. Through the meshing of the incomplete gear 19 and the complete gear 20, the drive shaft 16 can drive the driven shaft 17. When the toothless surface of the incomplete gear 19 corresponds to the complete gear 20, the driven shaft 17 cannot drive the drive shaft 16 to rotate, thus realizing the one-way linkage between the drive shaft 16 and the driven shaft 17, and thus realizing the one-way linkage between the dust collector bag 6 and the cleaning brush 11.

[0033] See Figure 7 and Figure 9In this embodiment, each set of drive shafts 16 is provided with multiple rope reels 21, and lifting ropes 22 are wound on the rope reels 21. The lifting ropes 22 are connected to the cleaning brush 11. When the drive shaft 16 rotates, the cleaning brush 11 can be driven to rise and fall through the lifting ropes 22 to clean the inner wall of the isolation cylinder 9.

[0034] See Figure 7 In this embodiment, the driven shaft 17 is located on one side of the dust collector bag 6, and the axis of the driven shaft 17 is perpendicular to the axis of the dust collector bag 6. A worm gear 23 is provided on the driven shaft 17, and a worm wheel 24 is provided on the dust collector bag 6 near the driven shaft 17. The worm wheel 24 meshes with the worm gear 23 for transmission. When the drive shaft 16 drives the driven shaft 17 to rotate, the dust collector bag 6 near the driven shaft 17 can be driven to rotate through the meshing transmission of the worm wheel 24 and the worm gear 23, and the other dust collector bags 6 can be driven to rotate synchronously through the transmission of the drive belt.

[0035] See Figure 3 and Figure 4 In this embodiment, a sealing spring 26 is provided on the side wall of the airflow channel 10 away from the air inlet slot 25. The free end of the sealing spring 26 extends through the air inlet slot 25 into the isolation cylinder 9, and this end is connected to a sealing plate 27. The sealing plate 27 is configured to be driven by the airflow of the intake and exhaust gases to move radially toward the axis of the isolation cylinder 9 to seal the air inlet slot 25. In the initial state, under the action of the sealing spring 26, the outer wall of the sealing plate 27 is in contact with the inner wall of the isolation cylinder 9. At this time, the inner wall of the cleaning brush 11 can be in contact with the inner wall of the sealing plate 27 and the inner wall of the isolation cylinder 9. The cleaning brush 11 can slide up and down in the channel inside the sealing plate 27 and the isolation cylinder 9 and outside the dust collector bag 6. When the cleaning brush 11 slides up and down, it seals the air inlet slot 25. The inner wall of the plate 27 and the isolation cylinder 9 is cleaned. When the exhaust gas enters through the airflow channel 10, the airflow exerts force on the sealing plate 27, driving the sealing plate 27 to move radially toward the axis of the isolation cylinder 9. An air intake gap is formed between the sealing plate 27 and the inner wall of the isolation cylinder 9, and the exhaust gas enters the isolation cylinder 9 through this gap. When cleaning the dust collector bag 6, under the action of the pulse jet pipe 8, the airflow is sprayed from the center of the axis of the dust collector bag 6 to the outside. At this time, the sealing spring 26, in conjunction with the pressure difference of the sprayed airflow, ensures that the outer wall of the sealing plate 27 is tightly attached to the inner wall of the isolation cylinder 9, preventing the sprayed dust from entering the airflow channel 10 in reverse through the air intake groove 25. It also ensures that there is no obstruction on the lifting path of the cleaning brush 11.

[0036] See Figure 3 and Figure 4In this embodiment, the isolation cylinder 9 is a closed cylinder with an opening at the bottom to meet the requirement that dust falls into the dust collection hopper 2 during cleaning. The air inlet groove 25 is opened along the axial direction of the isolation cylinder 9. The upper end of the air inlet groove 25 does not extend to the top of the isolation cylinder 9. In the initial state, the cleaning brush 11 is stored in the isolation cylinder 9 at the position where the air inlet groove 25 is not opened.

[0037] See Figure 3 and Figure 4 In this embodiment, the isolation cylinder 9 is inclined on both sides of the air inlet groove 25, and the inclined surface is inclined towards one side of the air inlet groove 25. The inclined surface ensures that the exhaust gas flow smoothly into the isolation cylinder 9.

[0038] See Figure 3 and Figure 4 In this embodiment, multiple sets of airflow channels 10 are provided inside the housing 1. Each set of airflow channels 10 corresponds to multiple sets of isolation cylinders 9 and is connected through the air inlet slot 25.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
