Description

Technical Field

[0001] This utility model relates to the field of flue gas dust removal technology, specifically, to a high-temperature flue gas dust removal device. Background Technology

[0002] For environmental protection workers in the metallurgical industry, exploring new paths for high-temperature flue gas treatment and energy-saving technologies that suit my country's national conditions is an urgent and arduous task. Standards related to the technical performance of dust collectors, such as purification efficiency and air leakage rate, play a certain role in regulating the performance and manufacturing quality of individual dust collector equipment. Currently, when conducting environmental protection acceptance of pollution control facilities, it is unreasonable to emphasize the purification efficiency of dust collectors and the safety hazards of manual cleaning, because the dust concentration and dust particle dispersion of the treated flue gas will directly affect the purification efficiency. A single assessment of purification efficiency is one-sided.

[0003] When treating high-temperature flue gas from steel metallurgy, the existing method involves filtering impurities from the flue gas using multi-layer filter plates. However, it is inconvenient to continuously clean the pores on the filter plates, which can easily lead to clogging of the mesh and reduce the filtration effect on high-temperature flue gas. Utility Model Content

[0004] This invention provides a safe high-temperature flue gas dust removal device that can overcome some or all of the defects of the prior art.

[0005] According to the present invention, a safe high-temperature flue gas dust removal device includes a device body detachably disposed at the high-temperature flue gas outlet. The device body includes a pipe body, and an inner cavity is formed inside the pipe body. A first filter plate and a second filter plate are disposed in the inner cavity. The second filter plate divides the filter cavity into a filter cavity and an outlet cavity. A support is disposed in the outlet cavity. A dual-axis motor is disposed at the support. A cleaning component is rotatably disposed at the output end of the dual-axis motor. The cleaning component is used to simultaneously clean the first filter plate, the second filter plate, and the inner wall of the filter cavity.

[0006] By setting up a first filter plate and a second filter plate, high-temperature flue gas is filtered in multiple stages, effectively removing dust and impurities from the flue gas, improving purification efficiency. In conjunction with the cleaning component, the first filter plate, the second filter plate, and the inner wall of the filter chamber can be cleaned simultaneously, avoiding the problem of filter hole blockage and ensuring the continuous and efficient operation of this device.

[0007] Preferably, the cleaning assembly includes a rotating shaft located at one output end of a dual-axis motor. The rotating shaft passes through the second filter plate and the first filter plate and is located inside the filter chamber. A cleaning arm and a scraper arm are detachably provided at the rotating shaft. The cleaning arm is used to clean the side wall of the first filter plate near the high-temperature flue gas outlet and the inner wall of the filter chamber. The scraper arm is used to clean the second filter plate and the corresponding side walls of the first and second filter plates.

[0008] With the cleaning arm and scraper arm working together, the cleaning arm is responsible for cleaning the side wall of the first filter plate near the high-temperature flue gas outlet and the inner wall of the filter chamber, effectively removing dust and impurities attached to these areas. The scraper arm is used to clean the second filter plate and the corresponding side wall between the first and second filter plates, preventing the pores on the filter plates from being blocked and ensuring filtration efficiency.

[0009] Understandably, since the first filter plate is used for the first filtration, it filters out a large number of impurities. The scraping arm and cleaning arm clean both sides of the first filter plate at the same time, reducing the number of manual cleanings and lowering the probability of personnel being exposed to hazardous environments. It also prevents the first filter plate from becoming clogged and affecting subsequent secondary filtration.

[0010] Preferably, a fan blade is provided at the output end of the other end of the dual-shaft motor, and the fan blade is used to exhaust the gas in the exhaust chamber.

[0011] Through the above structure, the rotation of the fan blades generates airflow, which enhances the flow speed of the gas in the exhaust chamber. This helps to discharge the filtered clean gas more smoothly from the exhaust chamber, avoiding the stagnation and accumulation of gas inside the exhaust chamber.

[0012] Understandably, the dual-axis motor drives both the cleaning components and the fan blades simultaneously, enabling cleaning and exhaust to proceed in sync, reducing energy consumption and improving overall work efficiency.

[0013] Preferably, an opening is formed at the bottom wall of the filter chamber, and a collection box for collecting impurities is detachably provided at the bottom wall of the tube corresponding to the opening.

[0014] The design of the inlet allows impurities removed by the cleaning components to fall into the collection box, which not only prevents impurities from accumulating in the filter chamber but also facilitates centralized processing and cleaning of impurities.

[0015] Understandably, the collection box is designed to be detachable, allowing users to easily remove and clean the impurities inside, thus ensuring the continuous and efficient operation of the device.

[0016] Preferably, a flange is formed at one end of the pipe body corresponding to the filter chamber, and a connecting end is formed at the flange that extends into the high-temperature flue gas outlet.

[0017] The flange design allows for easy connection to the high-temperature flue gas outlet. The flange is secured to the outlet using bolts or other fasteners, enabling installation. Similarly, disassembly or replacement is easily accomplished by simply loosening the fasteners. Attached Figure Description

[0022] Example 1

[0023] Please see Figure 1-3 This embodiment provides a high-temperature flue gas dust removal device, which includes a device body 100 detachably disposed at the high-temperature flue gas outlet. The device body 100 includes a pipe body 110, and an inner cavity is formed inside the pipe body 110. A first filter plate 230 and a second filter plate 240 are disposed in the inner cavity. The second filter plate 240 divides the filter cavity 210 into a filter cavity 210 and an exhaust cavity 211. A bracket is disposed in the exhaust cavity 211. A dual-axis motor 250 is disposed at the bracket. A cleaning component is rotatably disposed at the output end of the dual-axis motor 250. The cleaning component is used to simultaneously clean the first filter plate 230, the second filter plate 240, and the inner wall of the filter cavity 210.

[0024] The high-temperature flue gas dust removal device disclosed herein uses a first filter plate 230 and a second filter plate 240 to perform multi-stage filtration of high-temperature flue gas, effectively removing dust and impurities from the flue gas, improving purification efficiency. In conjunction with a cleaning component, it can simultaneously clean the first filter plate 230, the second filter plate 240, and the inner wall of the filter chamber 210, avoiding the problem of filter hole blockage and ensuring the continuous and efficient operation of the device.

[0025] In this embodiment, the cleaning component includes a rotating shaft 260 located at one output end of the dual-axis motor 250.

The scraper arm 290 is used to clean the second filter plate 240 and the corresponding side walls of the first filter plate 230 and the second filter plate 240.

[0026] With the coordinated arrangement of the cleaning arm 280 and the scraper arm 290, the cleaning arm 280 is responsible for cleaning the side wall of the first filter plate 230 near the high-temperature flue gas outlet and the inner wall of the filter chamber 210, effectively removing dust and impurities attached to these areas. The scraper arm 290 is used to clean the second filter plate 240 and the corresponding side wall between the first filter plate 230 and the second filter plate 240, preventing the pores on the filter plate from being blocked and ensuring filtration efficiency.

[0027] Understandably, since the first filter plate 230 is used for the first filtration, it filters out a lot of impurities. The scraper arm 290 and the cleaning arm 280 clean both sides of the first filter plate 230 at the same time to prevent the first filter plate 230 from becoming clogged and affecting the subsequent secondary filtration.

[0028] In this embodiment, a fan blade 270 is provided at the other output end of the dual-axis motor 250. The fan blade 270 is used to exhaust the gas in the exhaust chamber 211.

[0029] Through the above structure, the rotation of the fan blade 270 generates airflow, which enhances the flow speed of the gas in the exhaust chamber 211, helps to discharge the filtered clean gas more smoothly from the exhaust chamber 211, and avoids the stagnation and accumulation of gas inside the exhaust chamber 211.

[0030] Understandably, the dual-axis motor 250 simultaneously drives the cleaning assembly and the fan blades 270, enabling simultaneous cleaning and exhaust, reducing energy consumption, and improving overall work efficiency.

[0031] In this embodiment, an opening 220 is formed at the bottom wall of the filter chamber 210, and a collection box 120 for collecting impurities is detachably provided at the bottom wall of the tube body 110 corresponding to the opening 220.

[0032] The design of the inlet 220 allows impurities removed by the cleaning components to fall into the collection box 120, which not only prevents impurities from accumulating in the filter chamber 210, but also facilitates the centralized processing and cleaning of impurities.

[0033] Understandably, the collection box 120 is designed to be detachable, allowing users to easily remove and clean the impurities inside, thus ensuring the continuous and efficient operation of the device.

[0034] In this embodiment, a flange 310 is formed at one end of the tube body 110 corresponding to the filter chamber 210, and a docking end 130 extending into the high-temperature flue gas outlet is formed at the flange 310.

[0035] The flange 310 allows for easy connection to the high-temperature flue gas outlet. The flange 310 is secured to the outlet using bolts or other fasteners, thus enabling installation. Similarly, disassembly or replacement of the device is easily accomplished by simply loosening the fasteners.

[0036] The connection between flange 310 and the high-temperature flue gas outlet is sealed with a gasket or sealant to prevent flue gas leakage.

[0037] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
