Description

Technical Field

[0001] This utility model relates to the field of ceramic filter cartridge technology, specifically a ceramic filter cartridge for dust removal and denitrification of smelting flue gas. Background Technology

[0002] With economic development, my country has many heavy industrial factories, and the flue gas emitted by many of these factories contains gases harmful to the environment. Flue gas that does not meet emission standards is not allowed to be emitted. In particular, smelting plants need to desulfurize and denitrify their flue gas. Existing smelting plants need to build denitrification and desulfurization towers and flue gas dust removal systems to ensure that the emitted gases meet emission standards, which increases the cost of flue gas treatment.

[0003] In the prior art, such as the ceramic filter cartridge for flue gas dust removal, desulfurization, and denitrification disclosed in CN217829330U, the outer wall of the inner cylinder is provided with a protruding ridge. The side of the protruding ridge away from the outer wall of the inner cylinder is an arc-shaped surface. Both the outer wall of the inner cylinder and the arc-shaped surface of the protruding ridge are coated with a denitrification catalyst layer. By adding the protruding ridge, the contact area between the air entering and the outer wall of the inner cylinder is increased, ensuring that the flue gas is in full contact with the denitrification catalyst layer when entering the inner cylinder, thereby achieving flue gas denitrification and increasing the flue gas treatment capacity.

[0004] During our testing of the above-mentioned equipment, although the addition of ridges increased the contact area for air entry, the outer wall of the ridges and ceramic inner cylinder, while blocking large dust particles to facilitate subsequent denitrification, also experienced continuous accumulation of dust and debris during filtration. This resulted in a short effective filtration time and consequently, poor subsequent filtration performance. Utility Model Content

[0005] The purpose of this invention is to provide a ceramic filter cartridge for dust removal and denitrification of smelting flue gas, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic filter cartridge for dust removal and denitrification of smelting flue gas, comprising a ceramic filter cartridge, the outer wall of which is provided with protruding ribs, the ceramic filter cartridge being disposed within a machine body, a sliding door assembly being provided at the lower part of the outer wall of the machine body, and an anti-clogging assembly being provided on the inner wall of the machine body, the anti-clogging assembly comprising:

[0008] A partition is fixedly connected to the inner wall of the machine body. A connecting ring is fixedly connected to the bottom end of the partition. An installation ring is fixedly connected to the bottom end of the partition. A protrusion is fixedly connected to the outer wall of the installation ring. A slider is slidably connected to the outer wall of the reciprocating lead screw. A lifting frame is fixedly connected to the outer wall of the slider. A collar is fixedly connected to the end of the lifting frame. A nylon brush is fixedly connected to the inner wall of the collar.

[0009] Preferably, the number of nylon brushes is several, and the several nylon brushes are arranged in a circumferential array and fixed on the inner wall of the collar.

[0010] Preferably, the lifting frame is slidably connected in the opening of the partition, and the outer wall of the lifting frame is adapted to the opening of the partition.

[0011] Preferably, the center line of the ceramic filter cartridge is on the same straight line as the center line of the mounting ring and the center line of the connecting ring.

[0012] Preferably, the inner wall of the machine body is provided with a stabilizing component, the stabilizing component includes a vertical rod, the vertical rod is fixedly connected between the machine body and the ceramic filter cylinder, and the collar is provided with a sliding hole.

[0013] Preferably, the sliding holes are provided in two sets, and the two sets of sliding holes are arranged on both sides mirroring the center plane of the lifting frame on the collar.

[0014] Preferably, the inner wall of the sliding hole is adapted to the outer wall of the vertical rod.

[0015] Compared with the prior art, this utility model provides a ceramic filter cartridge for dust removal and denitrification of smelting flue gas, which has the following beneficial effects:

[0016] 1. This ceramic filter cartridge for dust removal and denitrification of smelting flue gas undergoes initial dust removal when the exhaust gas passes through the ceramic fiber filter cartridge and the convex ribs. The exhaust gas then enters the ceramic filter cartridge for denitrification. After denitrification, the gas is discharged from the exhaust port. During operation, a motor can be started to rotate the reciprocating screw, causing the limited slider to move the lifting frame and the collar. This movement of the nylon brush scrapes away large dust particles accumulated on the outer wall of the ceramic filter cartridge and the convex ribs, facilitating better initial dust filtration. Furthermore, the periodic movement of the collar and nylon brush is caused by the protrusions on the mounting ring, which dislodges the dust trapped in the nylon brush, ensuring its self-cleaning properties.

[0017] 2. In this ceramic filter cartridge for dust removal and denitrification of smelting flue gas, the sliding hole and vertical rod guide the collar when the collar and nylon brush are displaced, making the collar more stable when following the movement of the lifting frame and slider. This ensures the effectiveness of the nylon brush in removing waste dust from the ceramic filter cartridge and the outer wall of the convex edge, and further improves the overall practicality.

[0026] 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.

[0027] like Figures 1-7As shown, this utility model provides a technical solution: a ceramic filter cartridge for dust removal and denitrification of smelting flue gas, including a ceramic filter cartridge 1, the outer wall of the ceramic filter cartridge 1 is provided with a protruding rib 2, the ceramic filter cartridge 1 is disposed inside a machine body 3, a sliding door assembly 4 is provided at the lower part of the outer wall of the machine body 3, an anti-clogging assembly 5 is provided on the inner wall of the machine body 3, the anti-clogging assembly 5 includes an air inlet 501, the air inlet 501 is opened on the outer wall of the machine body 3, an exhaust port 502 is opened on the outer wall of the machine body 3, a mounting bracket 503 is fixedly connected to the outer wall of the machine body 3, a motor 504 is fixedly connected to the outer wall of the mounting bracket 503, the output end of the motor 504 passes through the mounting bracket 503 and is fixedly connected to a reciprocating lead screw 505, and a horizontal plate 506 is fixedly connected to the inner wall of the machine body 3.

[0028] Furthermore, the partition 507 is fixedly connected to the inner wall of the body 3. A connecting ring 508 is fixedly connected to the bottom end of the partition 507. An installation ring 509 is fixedly connected to the bottom end of the partition 507. A protrusion 510 is fixedly connected to the outer wall of the installation ring 509. A slider 511 is slidably connected to the outer wall of the reciprocating screw 505. A lifting frame 512 is fixedly connected to the outer wall of the slider 511. A collar 513 is fixedly connected to the end of the lifting frame 512. A nylon brush 514 is fixedly connected to the inner wall of the collar 513.

[0029] In the embodiments of this utility model, the number of nylon brushes 514 is several, and the several nylon brushes 514 are arranged in a circumferential array on the inner wall of the collar 513. The lifting frame 512 is slidably connected to the corresponding opening of the partition 507, and the lifting rod of the lifting frame 512 is adapted to the inner wall of the opening of the partition 507. The center line of the ceramic filter cylinder 1, the center line of the mounting ring 509, and the center line of the connecting ring 508 are all on the same straight line.

[0030] Furthermore, the inner wall of the body 3 is provided with a stabilizing component 6, which includes a vertical rod 602. The vertical rod 602 is fixedly connected between the body 3 and the ceramic filter cartridge 1. The collar 513 has two sets of sliding holes 601 on its horizontal surface. The two sets of sliding holes 601 are mirror images of the center plane of the lifting frame 512 on both sides of the collar 513. The inner wall of the sliding hole 601 is adapted to the outer wall of the vertical rod 602, so that the collar 513 can slide smoothly on the outer wall of the vertical rod 602.

[0031] In this invention, before daily use, an input pipe is installed on the air inlet 501, and a suction fan or output pipe is connected to the exhaust port 502. During dust removal and denitrification, gas is drawn in through the air inlet 501. The exhaust gas undergoes initial dust removal as it passes through the ceramic filter cartridge 1 and the protruding ribs 2. As the flue gas enters the ceramic filter cartridge 1, a denitrification catalyst is coated on the inner wall of the ceramic filter cartridge 1, enabling denitrification. After denitrification, the gas is discharged from the exhaust port 502. During use, the motor 504 can be started to drive the reciprocating screw 505 to rotate, thereby causing the limited slider 511 to rise. The lowering frame 512 and the collar 513 are displaced, which allows the nylon brush 514 to scrape away large dust particles accumulated on the outer wall of the ceramic filter cartridge 1 and the ridge 2 during the displacement. A wire brush can also be used here, so that the ceramic filter cartridge 1 and the ridge 2 can effectively filter the waste dust in the initial stage. When the collar 513 and the nylon brush 514 are periodically displaced, they are rubbed by the protrusion 510 on the mounting ring 509, so that the waste dust mixed in the nylon brush 514 falls off, ensuring the self-cleaning property of the nylon brush 514. Later, the sliding door assembly 4 can be opened periodically, i.e., the sliding door can be moved, to replace the dust accumulated inside and the ceramic filter cartridge 1 and other components.

[0032] When the collar 513 and the nylon brush 514 are displaced, the sliding hole 601 and the vertical rod 602 guide the collar 513, making the collar 513 more stable when it moves with the lifting frame 512 and the slider 511. This ensures that the nylon brush 514 can effectively remove dust from the outer wall of the ceramic filter cartridge 1 and the convex ridge 2, and further improves the overall practicality and stability.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
