Abstract
Description
Technical Field
[0001] This utility model relates to the field of sintering flue gas dust removal technology, specifically a sintering flue gas circulating dust removal device. Background Technology
[0002] Sintering flue gas is a mixture of gases containing various pollutants generated during the high-temperature sintering process of raw materials such as iron ore powder, fuel (such as coke), and flux (such as limestone) in the iron and steel industry. It is one of the main sources of air pollution for iron and steel enterprises. Its composition and properties are closely related to factors such as sintering raw materials and process conditions, so dust removal processes are required in the later stages of treatment.
[0003] An existing patent (publication number: CN215311011U) discloses a dust removal device for sintering machine flue gas that is easy to collect. By setting up an installation cover, a sealing plate, a dust removal inner cylinder, a dust collection box, a connecting filter, and a dust removal filter, the flue gas generated by sintering enters the dust removal outer cylinder through the air inlet pipe at one end of the dust removal outer cylinder, and then enters the dust removal inner cylinder through the connecting filter. After being blocked by the dust removal filter, solid impurities in the flue gas are filtered out. The impurities fall into the dust collection box for collection after being blocked by the dust removal filter. This facilitates the filtration and collection of solid impurities in the flue gas, making the flue gas treatment more efficient.
[0004] To address the aforementioned issues, while existing patents offer solutions that improve flue gas treatment efficiency through the integration of components such as mounting covers, these solutions, in practice, occupy a large area, resulting in wasted space and making them unsuitable for smaller spaces, thus limiting their application. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Given that the existing technology has the problem of occupying a large area as a whole, resulting in wasted space, it is not suitable for smaller spaces and thus has limited use.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A sintering flue gas circulating dust removal device includes a conveying shell, a connecting shell fixedly installed at one end of the conveying shell, a filter plate embedded in one side of the inside of the conveying shell, and a circulation mechanism provided at the top of the conveying shell.
[0009] The circulation mechanism includes a connecting shell, which is fixedly installed at the top of the conveying shell, and a circulation shell extends through one side of the connecting shell. A fixing shell is fixedly installed at the bottom of the connecting shell, and an installation shell is fixedly installed below the fixing shell. A filter screen is embedded in the outer wall of the installation shell.
[0010] As a further improvement of this utility model: a flow groove is provided on one side of the conveying shell corresponding to the filter plate, and a connection hole is provided on the end of the connecting shell facing the conveying shell.
[0011] As a further improvement of this utility model: a fixing frame is fixedly installed inside the connecting shell, and a filter bag is embedded in the inner wall of the fixing frame.
[0012] As a further improvement of this utility model: the conveying shell is detachably connected to the connecting shell by bolts, and the conveying shell and the connecting shell are in communication.
[0013] As a further improvement of this utility model: an ion fan is embedded on one side of the circulation shell at the top of the conveying shell, and an emission mechanism is provided below the conveying shell.
[0014] As a further embodiment of this utility model: the emission mechanism includes a guide plate, which is fixedly installed on one side of the bottom filter plate inside the conveying shell, and a current collector is embedded in the outer wall of the guide plate.
[0015] As a further improvement of this utility model: a drop groove is provided on one side of the bottom guide plate inside the conveying shell, and a storage shell is fixedly installed at the bottom of the conveying shell.
[0016] As a further improvement of this utility model: the storage shell has an internal cavity, and a receiving shell is slidably connected inside the cavity, with a limiting plate fixedly installed at one end of the receiving shell. Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model achieves a dual filtration effect through the filter plate and filter bag. In conjunction with the connecting shell, circulation shell and fixed shell, it can allow the circulating gas to form a backflow for circulation, thereby filtering again. While maintaining gas flow, it improves the filtration effect of dust, powder and impurities. At the same time, it can reduce the size of the entire dust removal device, which only needs to be suspended from the ceiling with hanging rods, avoiding large space occupation and waste.
[0018] 2. This utility model, through the cooperation of an ion fan and a collector, can collect dust and other particles in the flowing gas. It can fully capture dust and other particles during the gas flow process, and after the gas flow is completed, the ion fan and collector can be closed, and the adsorbed dust and other particles can be guided by the guide plate into the collection shell for unified collection.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0028] Example 1:
[0029] Please see Figures 1-4 This is the first embodiment of the present invention.
[0030] This embodiment provides a sintering flue gas circulating dust removal device, including a conveying shell 1, a connecting shell 2 fixedly installed at one end of the conveying shell 1, a filter plate 3 embedded in one side of the inside of the conveying shell 1, and a circulation mechanism 4 provided at the top of the conveying shell 1.
[0031] The circulation mechanism 4 includes a connecting shell 401, which is fixedly installed at the top of the conveying shell 1. A circulation shell 402 extends through one side of the connecting shell 401. A fixing shell 403 is fixedly installed at the bottom of the connecting shell 401. An installation shell 404 is fixedly installed below the fixing shell 403. A filter screen 405 is embedded in the outer wall of the installation shell 404.
[0032] Specifically, a flow groove 406 is provided inside the conveying shell 1 on one side corresponding to the filter plate 3, and a connection hole 407 is provided at the end of the connecting shell 2 facing the conveying shell 1.
[0033] Furthermore, the flow channel 406 allows impurities filtered by the filter plate 3 to fall off and escape from the interior of the conveying shell 1.
[0034] Specifically, a fixing bracket 408 is fixedly installed inside the connecting shell 2, and a filter bag 409 is embedded in the inner wall of the fixing bracket 408.
[0035] Furthermore, the filter bag 409 is made of the same material as the filter bag in the bag filter equipment, which further improves the filtration effect through double-layer filtration.
[0036] Specifically, the conveying shell 1 is detachably connected to the connecting shell 2 by bolts, and the conveying shell 1 and the connecting shell 2 are in communication.
[0037] Furthermore, the conveyor housing 1 and the connecting housing 2 are detachably connected, which facilitates regular disassembly and assembly for maintenance and cleaning of the internal components.
[0038] In use, when gas enters the conveying shell 1, it is filtered by the filter plate 3. The filter bag 409 is fixed inside the connecting shell 2 by the fixing frame 408 and unfolds to achieve double-layer filtration. Due to the material of the filter bag 409, the gas flow may be slow. Therefore, some gas enters the mounting shell 404 upwards, enters the connecting shell 401 through the fixing shell 403, and enters the conveying shell 1 again from the other end through the circulation shell 402 to form a circulation. During the circulation process, it is filtered again by the filter screen 405. The filtering positions of the filter plate 3 and the filter screen 405 correspond to the flow groove 406, which facilitates the removal of impurities from the conveying shell 1.
[0039] In summary, the double-layer filtration of filter plate 3 and filter bag 409 can further improve the dust removal effect. In conjunction with the connection shell 401 and circulation shell 402, some gas can be returned to one end of the conveying shell 1 for further filtration, which can fully filter impurities in the gas and improve the purification level. At the same time, the overall conveying shell 1 has a rectangular hollow structure, which can be fixed to the ceiling or above the corresponding equipment through fitting components such as hanging rods, thereby saving space and using it in a smaller location, thus improving the rational use of space.
[0040] Example 2:
[0041] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.
[0042] Specifically, an ion fan 5 is embedded on one side of the circulation shell 402 at the top of the conveying shell 1, and an exhaust mechanism 6 is provided below the conveying shell 1.
[0043] Furthermore, the ion fan 5 can increase the speed of gas flow and ionize the impurities contained in the gas.
[0044] Specifically, the emission mechanism 6 includes a guide plate 601, which is fixedly installed on one side of the filter plate 3 at the bottom inside the conveying housing 1, and a collector electrode 602 is embedded in the outer wall of the guide plate 601.
[0045] Furthermore, the current collector 602 can adsorb ionized impurities and dust, thereby effectively achieving dust removal.
[0046] Specifically, a drop groove 603 is provided on one side of the bottom guide plate 601 inside the conveying shell 1, and a storage shell 604 is fixedly installed at the bottom of the conveying shell 1.
[0047] Furthermore, the drop trough 603 facilitates the closing of the collector 602 after ventilation is completed, allowing the collected impurities and dust to be discharged through the drop trough 603.
[0048] Specifically, the storage shell 604 has an internal cavity 605, and a receiving shell 606 is slidably connected inside the cavity 605. A limiting plate 607 is fixedly installed at one end of the receiving shell 606.
[0049] Furthermore, the housing 606 and the limiting plate 607 form a drawer, which facilitates pulling it out to clean and collect dust and impurities stored inside.
[0050] In use, when the gas is discharged, the ion fan 5 ionizes the dust and impurities it contains. During the flow, the dust is adsorbed by the current collector 602 embedded in the guide plate 601. After the gas flow is complete, the current collector 602 is closed, and the dust and impurities slide down the inclined guide plate 601 and enter the placement cavity 605 of the storage shell 604 through the drop groove 603. At the same time, the placement cavity 605 corresponds to the flow groove 406, which facilitates the unified collection of the storage container composed of the storage shell 606 and the limiting plate 607, making it convenient for later disassembly and cleaning.
[0051] In summary, the combination of the ion fan 5 and the collector 602 can fully absorb dust and other particles from the flowing gas, preventing the flowing gas from containing a large amount of dust, which would affect the effect of subsequent treatment. In addition, the collection shell 604 and the containment shell 606 can collect these filtered dust and impurities in a unified manner, making it convenient for staff to collect and clean them in a unified manner later.
