Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically to a split-type multi-compartment combined dust collector filter bag. Background Technology

[0002] Traditional single-layer dust collector filter bags have significant drawbacks under high-temperature flue gas conditions: their single filter layer must simultaneously withstand the mechanical impact of large particles and the deep clogging of fine particles, leading to localized damage and reduced overall air permeability, significantly shortening their service life. Furthermore, due to the lack of a graded filtration mechanism, particles of all sizes deposit in a single filter layer, reducing filtration efficiency and increasing system pressure drop. In addition, the traditional structure lacks an integrated heat exchange device, resulting in the direct emission of waste heat from flue gas exceeding 300°C. This not only wastes energy but also accelerates the aging of the filter bag material due to sustained high temperatures, significantly increasing maintenance costs and energy consumption. This design is no longer sufficient to meet the dual requirements of modern industry for efficient dust removal and energy recovery.

[0003] Therefore, a split-type multi-compartment combined dust collector filter bag is proposed. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a split-type multi-compartment combined dust collector filter bag.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A split-type multi-compartment combined dust collector filter bag includes: The second support plate, the first support plate, and the third support plate are arranged in parallel from top to bottom; A first fixed cylinder and a heat exchange component are disposed at the bottom of the second support plate, and a second fixed cylinder is disposed at the bottom of the first support plate; The heat exchange component includes a heat exchange tube sleeved on the outside of the first fixed cylinder, and an inlet pipe and an outlet pipe connected to the heat exchange tube. The third fixing cylinder is installed at the bottom of the third support plate; A first dust removal filter bag fitted onto the outside of the second fixed cylinder and a second dust removal filter bag fitted onto the outside of the third fixed cylinder; Limiting components used to fix the first and second dust collector filter bags.

[0006] Furthermore, the limiting component includes a limiting hoop and a connecting ear, wherein the limiting hoop locks the filter bag opening by engaging with the connecting ear through bolts.

[0007] Furthermore, the third fixing cylinder, the first fixing cylinder, and the second fixing cylinder are coaxially arranged, and the diameter of the first fixing cylinder is smaller than that of the second fixing cylinder, and the diameter of the second fixing cylinder is smaller than that of the third fixing cylinder.

[0008] Furthermore, the heat exchange tube has a spiral coil structure and is tightly wound around the outer wall of the first fixed cylinder.

[0009] Furthermore, the first dust collector filter bag and the second dust collector filter bag have different filtration precision or materials, thus forming a graded filtration system.

[0010] Furthermore, the first support plate, the second support plate, and the third support plate are connected by connecting bolts.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model adopts a split multi-compartment combination design, using a second dust collector filter bag and a first dust collector filter bag for low-precision and high-precision graded filtration respectively, effectively dispersing the interception load of particles of different sizes, greatly reducing filter bag wear, and the stable frame composed of three-layer support plates combined with the fastening effect of limiting components ensures that the filter bag does not loosen or fall off under the impact of flue gas, significantly extending its service life.

[0012] 2. The heat exchange tube with a spiral coil structure of this utility model is closely matched with the first fixed cylinder to achieve efficient heat exchange when flue gas passes through, which not only recovers waste heat but also reduces the flue gas temperature. The coaxial arrangement of the second and third fixed cylinders optimizes the airflow path. With the selection of corrosion-resistant materials, a comprehensive solution that takes into account dust removal efficiency, heat recovery and equipment durability is formed.

[0019] like Figure 1-4As shown, a split-type multi-compartment combined dust collector filter bag includes: a second support plate 2, a first support plate 1, and a third support plate 10 arranged parallel from top to bottom. The three support plates (first support plate 1, second support plate 2, and third support plate 10) form a frame and are fixed by connecting bolts to ensure structural stability; a first fixing cylinder 6 and a heat exchange component 3 are disposed at the bottom of the second support plate 2, and a second fixing cylinder 5 is disposed at the bottom of the first support plate 1; the heat exchange component 3 includes a heat exchange tube 301 sleeved on the outside of the first fixing cylinder 6, and an inlet pipe 302 and an outlet pipe 303 communicating with the heat exchange tube 301; and a third fixing cylinder 5 is disposed at the bottom of the first support plate 1. The support plate 10 has a third fixed cylinder 8 at its bottom; a first dust removal filter bag 7 sleeved on the outside of the second fixed cylinder 5 and a second dust removal filter bag 9 sleeved on the outside of the third fixed cylinder 8; and a limiting component 4 for fixing the first dust removal filter bag 7 and the second dust removal filter bag 9. Specifically, in actual operation, the high-temperature flue gas first passes through the second dust removal filter bag 9 for low-precision filtration to intercept larger particles, and then enters the first dust removal filter bag 7 for high-precision filtration to capture fine particles. At the same time, when the flue gas passes through the heat exchange tube 301, it exchanges heat with the cooling medium in the heat exchange tube to achieve cooling and achieve the dual purpose of dust removal and waste heat recovery.

[0020] like Figure 4 As shown, the limiting component 4 includes a limiting clamp 401 and a connecting ear 402. The limiting clamp 401 locks the filter bag opening by cooperating with the connecting ear 402 through bolts. Specifically, the limiting clamp 401 locks the filter bag opening by cooperating with the connecting ear 402 through bolts, thereby ensuring that the filter bag will not loosen or fall off due to the impact of flue gas during operation, and ensuring the stability of the dust removal effect.

[0021] like Figure 2 As shown, the third fixing cylinder 8, the first fixing cylinder 6, and the second fixing cylinder 5 are coaxially arranged, and the diameter of the first fixing cylinder 6 is smaller than that of the second fixing cylinder 5, and the diameter of the second fixing cylinder 5 is smaller than that of the third fixing cylinder 8; specifically, the third fixing cylinder 8, the first fixing cylinder 6, and the second fixing cylinder 5 are all provided with ventilation holes; First dust filter bag 7 (fitted onto second fixed cylinder 5): high-precision filtration, capturing fine particles. The second dust collector filter bag 9 (fitted onto the third fixed cylinder 8): low-precision filtration, intercepts larger particles, forming a two-stage filtration system and extending the filter bag's lifespan.

[0022] like Figure 2 and 3As shown, the heat exchange tube 301 has a spiral coil structure and is tightly wound around the outer wall of the first fixed cylinder 6. Specifically, the heat exchange tube 301 is tightly wound around the outer wall of the first fixed cylinder 6 to increase the contact area and improve the heat exchange efficiency. The water inlet pipe 302 and the water outlet pipe 303 are connected to the external circulation system to introduce a cooling medium (such as water or heat transfer oil) for cooling the high-temperature flue gas and realizing heat exchange. This facilitates the utilization of the waste heat of the high-temperature flue gas. The heat exchange tube 301 can be fixed to the bottom of the second support plate 2 by means of clips or brackets. Both the first fixed cylinder 5 and the heat exchange tube 301 are made of corrosion-resistant materials and can be regularly flushed and maintained.

[0023] like Figure 2 As shown, the first dust collector filter bag 7 and the second dust collector filter bag 9 have different filtration precision or materials, forming a graded filtration system; specifically, the first dust collector filter bag 7 and the second dust collector filter bag 9 can be selected from different materials such as high temperature resistance and corrosion resistance according to the working conditions.

[0024] like Figure 2 As shown, the first support plate 1, the second support plate 2, and the third support plate 10 are connected by connecting bolts.

[0025] In summary: High-temperature flue gas first undergoes low-precision filtration through the second dust collector filter bag 9 outside the third fixed cylinder 8, intercepting larger particles; then, the flue gas rises into the first dust collector filter bag 7 outside the second fixed cylinder 5 below the first support plate 1 for high-precision filtration, capturing fine particles, forming a two-stage filtration system to extend the filter bag life. During this process, when the flue gas flows through the first fixed cylinder 6 at the bottom of the second support plate 2, it exchanges heat with the heat exchange tube 301 of the spiral coil structure outside it. The cooling medium circulates through the water inlet pipe 302 and the water outlet pipe 303 to achieve flue gas cooling and waste heat recovery. Finally, it can be discharged outward through the exhaust groove on the second support plate 2. The three-layer support plate is fixed to the frame by connecting bolts. The limiting clamp 401 of the limiting component 4 and the connecting ear 402 cooperate to lock the filter bag opening to ensure the stability of the filter bag. All fixed cylinders are equipped with vent holes and are made of corrosion-resistant materials, which are used with filter bags of different materials / precisions to adapt to high-temperature and corrosive working conditions, ultimately achieving the dual functions of dust removal and heat recovery.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
