Description

Technical Field

[0001] This utility model relates to the field of converter gas dust removal technology, specifically a converter gas metal filter bag dust removal device. Background Technology

[0002] The converter gas metal filter bag dust collector is a key piece of equipment used in converter gas purification systems in the metallurgical industry. It utilizes the high-temperature resistance and excellent filtration performance of metal fiber filter bags to purify the high-temperature, dust-rich gas generated during converter steelmaking. As the dust-laden gas passes through the filter bags, the dust is trapped on the filter bag surface, and the purified gas can be recycled or discharged in compliance with standards.

[0003] However, during the filtration process, dust gradually accumulates on the surface of the filter bag, forming a dust layer that increases filtration resistance and reduces dust removal efficiency. To maintain the air permeability and dust removal performance of the filter bag, it is necessary to regularly remove the accumulated dust from its surface. Currently, the commonly used cleaning methods are pulse jet cleaning and mechanical vibration. Pulse jet cleaning uses compressed air to instantly blow onto the filter bag, causing it to vibrate and generate reverse airflow, shaking off the dust. However, this method mainly works on the surface of the filter bag, and its cleaning effect is limited for deep layers of dust or highly adhesive dust. Some dust cannot be completely removed due to its strong adhesion, especially in high humidity or high-viscosity dust environments, where the cleaning effect is even worse. Mechanical vibration cleaning uses a mechanical device to knock or vibrate the filter bag, causing the dust on it to fall off. However, the intensity of mechanical vibration is insufficient to shake off the dense dust layer formed on the surface of the filter bag, especially when the dust particles are fine or highly adhesive, resulting in an unsatisfactory cleaning effect.

[0004] Existing dust removal technologies are insufficient to completely remove dust from the surface of filter bags, leading to a gradual increase in filter bag resistance and a decrease in dust removal efficiency. Ultimately, it is necessary to periodically remove the metal filter bags for cleaning. However, metal filter bags are usually installed inside pipelines, with a compact structure and limited space, making removal and installation troublesome, thus increasing maintenance workload and costs. Therefore, a converter gas metal filter bag dust removal device is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] 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.

[0024] Please see Figures 1 to 3 The converter gas metal filter bag dust removal device in this embodiment includes a furnace body 1 and a metal filter bag 12. The right side of the furnace body 1 is provided with a disassembly and assembly structure for disassembling and assembling the metal filter bag 12.

[0025] In this embodiment, the disassembly and assembly structure includes a flue gas pipe 2 fixedly connected to the exhaust end of the furnace body 1, a connecting pipe 3 fixedly connected to the right end of the flue gas pipe 2, a first mounting sleeve 4 fixedly connected to the right end of the connecting pipe 3, eight positioning mounting columns 5 fixedly connected to the right end of the first mounting sleeve 4, a side plate 14 fixedly connected to the outer peripheral wall of the furnace body 1, an electric slide 6 fixedly connected to the top of the side plate 14, a connecting rod 7 fixedly connected to the movable shaft of the electric slide 6, a sealing sleeve 8 fixedly connected to the top of the connecting rod 7, a second mounting sleeve 9 fixedly connected to the inner peripheral wall of the sealing sleeve 8, and a circular metal filter bag 12. The first mounting sleeve 4 and the second mounting sleeve 9 are the same size.

[0026] It should be noted that the sealing sleeve 8 will seal the connection between the first mounting sleeve 4 and the second mounting sleeve 9, thereby improving the sealing performance between the first mounting sleeve 4 and the second mounting sleeve 9.

[0027] In this embodiment, the second mounting sleeve 9 has eight positioning slots inside, and the eight positioning mounting posts 5 are slidably connected inside the eight positioning slots. The size of the positioning mounting posts 5 is adapted to the size of the positioning slots.

[0028] It should be noted that the positioning groove facilitates the positioning and installation of the first mounting sleeve 4 and the second mounting sleeve 9.

[0029] In this embodiment, the right end of the second mounting sleeve 9 is fixedly connected to the discharge pipe 10, the right end of the discharge pipe 10 is fixedly connected to the telescopic adjustment pipe 11, the left end of the metal filter bag 12 is fixedly connected to the mounting ring 13, the sealing sleeve 8 is slidably connected to the outer peripheral wall of the first mounting sleeve 4, the mounting ring 13 is slidably connected to the inner peripheral wall of the sealing sleeve 8, the metal filter bag 12 is slidably connected to the inner peripheral wall of the second mounting sleeve 9, the mounting ring 13 is located between the first mounting sleeve 4 and the second mounting sleeve 9, and the mounting ring 13 has eight limiting holes inside, and eight positioning mounting posts 5 are slidably connected inside the eight limiting holes respectively, and the size of the positioning mounting posts 5 is adapted to the limiting holes.

[0030] It should be noted that the positioning and mounting column 5 supports and limits the mounting ring 13, thereby improving the stability of the metal filter bag 12 installation.

[0031] In this embodiment, a pulse jet blowing device 15 is fixedly connected to the top of the side plate 14, and an air blowing pipe 16 is fixedly connected between the pulse jet blowing device 15 and the connecting pipe 3.

[0032] It should be noted that the pulse jet cleaning device 15 removes the accumulated dust on the surface of the metal filter bag 12 by instantaneously blowing compressed air, thus restoring its filtration performance. When the metal filter bag 12 is filtering dusty gas, dust will gradually accumulate on the surface of the filter bag, leading to increased airflow resistance and affecting dust removal efficiency. At this time, the pulse jet cleaning system releases high-pressure compressed air through the pulse valve, forming a strong shock wave and reverse airflow, which causes the filter bag to expand and vibrate instantly, thereby shaking off the attached dust, ensuring that the filter bag maintains good air permeability and filtration effect, and extending its service life.

[0033] The working principle of the above embodiments is as follows:

[0034] When the dust filtered by the metal filter bag 12 needs to be treated, the pulse jet cleaning device 15 is first started to treat the metal filter bag 12. At this time, some dust will still adhere to the metal filter bag 12. Then, the electric slide table 6 is started to drive the sealing sleeve 8 and the second mounting sleeve 9 to the right through the connecting rod 7. At this time, the metal filter bag 12 is separated from the second mounting sleeve 9. Then the mounting ring 13 can be slid to the right from the positioning mounting post 5. At this time, the metal filter bag 12 can be removed and cleaned.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
