Description

Technical Field

[0001] This utility model relates to the technical field of flue gas dust removal structure, specifically to a metal filter bag and dust collector. Background Technology

[0002] Currently, dust collectors are generally used to remove dust from flue gas. Most dust collectors use filter bags made of non-metallic woven fabrics such as non-woven fabrics and synthetic fibers as filter media. However, due to the high temperature of flue gas, the use of these materials is limited. As an alternative, metal filter bags have emerged. However, metal filter bags present inconvenience when damaged and requiring sealing or replacement. To address this issue, Chinese utility model patent application number 202322801686.1 discloses a metal filter bag and dust collector. This design transforms the integral metal filter bag into a multi-segment composite filter bag, allowing for disassembly and replacement in segments, thus improving the convenience and efficiency of disassembly and replacement. However, in this structure, disassembling a single segment still requires moving the entire filter bag upwards and then disassembling it sequentially, limiting the improvement in ease of disassembly and replacement and leaving room for improvement. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the aforementioned background technology by providing an easy-to-assemble and disassemble metal filter bag and a dust collector using the metal filter bag.

[0004] To achieve the above objectives, this utility model provides a metal filter bag and dust collector, which adopts the following technical solution:

[0005] A metal filter bag includes a top plate with a connecting portion on its lower end face. The connecting portion connects to the filter bag body. The lower end of the filter bag body is connected to a second connecting portion, and the lower end of the second connecting portion is connected to a second filter bag body. The lower end of the second filter bag body has an unsealed portion. The lower end face of the connecting portion has a downward-facing groove. The upper end face of the second connecting portion has a second groove and the lower end face has an upward-facing groove, respectively. The upper end face of the unsealed portion has a downward-facing groove. A baffle is installed between the grooves and the second groove, and a second baffle is installed between the third groove and the fourth groove. The baffle and the second baffle are used to block flue gas from passing through the filter bag body and the second filter bag body. Multiple sets of second connecting portions and second filter bag bodies are provided. The baffle and the second baffle have the same structure. The baffle includes two sets of arc-shaped plates. The ends of the two arc-shaped plates abut against each other. A sealing plate is provided between the two arc-shaped plates, blocking the contact point of the two arc-shaped plates. The sealing plate is bolted to the arc-shaped plates.

[0006] A dust collector includes two identical dust collection chambers, each with a tube sheet and the aforementioned metal filter bags. The two dust collection chambers are connected to a flue gas inlet pipe and a flue gas outlet pipe.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] This invention divides the metal filter bag into sections, and each section can be fitted with a baffle to seal the damaged filter bag, ensuring the dust removal effect of the remaining normal filter bags. The baffles do not require raising the overall height of the filter bag, making operation convenient. At the same time, the two dust collection boxes can also achieve continuous flow of flue gas, ensuring dust removal efficiency. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model;

[0010] Figure 2 This is a schematic diagram of the dust collector of this utility model;

[0011] In the diagram: 1 top plate, 2 connecting part, 3 filter bag body, 4 second connecting part, 5 second filter bag body, 6 end sealing part, 7 groove, 8 second groove, 9 third groove, 10 fourth groove, 11 dust collector box, 12 tube sheet, 13 flue gas inlet pipe, 14 flue gas outlet pipe. Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1 As shown, a metal filter bag includes a top plate 1, a connecting part 2 on the lower end face of the top plate, the connecting part connecting to the filter bag body 3, the lower end of the filter bag body connecting to a second connecting part 4, the lower end of the second connecting part connecting to a second filter bag body 5, the lower end of the second filter bag body having an unsealed part 6, the lower end face of the connecting part having a downward groove 7, the upper end face of the second connecting part having a downward groove 8 and a third groove 9 respectively, the upper end face of the unsealed part having a downward groove 10, the upper end face of the unsealed part having a downward groove 10, a baffle is arranged between the groove and the second groove, and a second baffle is arranged between the third groove and the fourth groove, the baffle and the second baffle are used to block flue gas from passing through the filter bag body and the second filter bag body.

[0014] Preferably, the second connecting part and the second filter bag body are provided in multiple sets.

[0015] Furthermore, the first and second baffles have the same structure. The first baffle includes two sets of arc-shaped plates, with their ends abutting against each other to enclose and block the filter bag body. A sealing plate is provided between the arc-shaped plates to block the contact point between the two arc-shaped plates. The sealing plate and the arc-shaped plates can be connected by bolts.

[0016] like Figure 2 As shown, a dust collector includes two identical dust collection chambers 11. Each dust collection chamber has a tube sheet 12, on which the aforementioned metal filter bags are installed. The two dust collection chambers are connected to a flue gas inlet pipe 13 and a flue gas outlet pipe 14. Valves are installed on the connecting pipes for control.

[0017] The working principle of this utility model is as follows: flue gas enters a dust collection box, passes through metal filter bags for dust removal, and then exits from the flue gas outlet pipe. When a metal filter bag or a section of filter bag is damaged, the flue gas enters another dust collection box to seal the damaged filter bags. When the number of damaged filter bags reaches a certain number, they are disassembled and replaced. Overall, this improves the convenience of disassembling and replacing damaged metal filter bags while ensuring the dust removal effect.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
