Description

Technical Field

[0001] This utility model relates to the technical field of industrial flue gas treatment equipment, specifically to an anti-collision device suitable for ceramic fiber filter tubes. Background Technology

[0002] In the current field of industrial flue gas treatment, integrated desulfurization, denitrification, and dust removal equipment, with its integrated dust removal, desulfurization, and denitrification functions and modular design, can significantly improve pollutant removal efficiency and reduce operating costs, and has become the mainstream technology and equipment. Ceramic fiber filter tubes, as the core filtration component of this equipment, directly determine the final dust removal, desulfurization, and denitrification effects of the equipment due to their operational stability. These ceramic fiber filter tubes are made primarily of ceramic fiber and are high-temperature resistant filter elements. They not only possess outstanding advantages such as high temperature resistance, corrosion resistance, long service life, and high filtration accuracy, but can also be widely adapted to exhaust gas purification scenarios in various industries such as glass, cement, steel, power, and chemicals, providing crucial support for achieving compliant industrial exhaust gas emissions.

[0003] However, existing technologies for applying ceramic fiber filter tubes still have significant shortcomings: ceramic fiber filter tubes are typically installed inside the perforations of the tube sheet in integrated desulfurization, denitrification, and dust removal equipment. Due to factors such as fluctuating operating conditions and material aging, the risk of breakage cannot be completely avoided. More importantly, once a filter tube breaks, it will directly collide with surrounding normally operating filter tubes during its fall, causing the damage area to expand further and ultimately triggering a chain reaction of simultaneous failure of multiple filter tubes, severely impacting the overall operational stability of the equipment.

[0004] Currently, industry solutions to this problem focus solely on enhancing the strength of the ceramic fiber filter tubes themselves. Specific measures include optimizing material formulations, improving structural processes, and strengthening quality control. However, in practical application, these measures can only reduce the initial probability of filter tube breakage to a certain extent. They cannot fundamentally prevent the chain reaction caused by a broken tube colliding with surrounding filter tubes. Therefore, it is still difficult to avoid the problem of a single broken filter tube colliding with surrounding normal filter tubes during its fall and causing secondary breakage. Consequently, multiple broken ceramic fiber filter tubes can lead to pressure imbalance in the dust collection system and cause equipment failure. Utility Model Content

[0005] The purpose of this invention is to provide an anti-collision device suitable for ceramic fiber filter tubes, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An anti-collision device for ceramic fiber filter tubes includes a perforated plate and an anti-collision assembly for separating adjacent ceramic fiber filter tube bodies.

One end of the ceramic fiber filter tube body passes through the hole and is placed in the placement area. The other end of the ceramic fiber filter tube body is fixedly connected to the perforated plate via a filter tube flange. A limiting component for blocking the ceramic fiber filter tube body is provided at the bottom of the placement area. The anti-collision assembly is made of corrosion-resistant and high-temperature resistant material.

[0007] Preferably, the anti-collision component is a columnar anti-collision cage, the anti-collision cage corresponds to the plate hole of the tube sheet, and one end of the anti-collision cage is fixedly connected to the plate hole of the tube sheet, and the placement area is located in the inner cavity of the anti-collision cage.

[0008] Preferably, the limiting component is a retaining ring, which is fixedly connected to the end of the anti-collision cage away from the flower plate.

[0009] Preferably, the longitudinal cross-sectional shape of the crash cage is circular or square.

[0010] Preferably, the anti-collision component consists of at least two anti-collision frames arranged in a cross pattern. Each anti-collision frame is surrounded by cross-bracing to form several placement areas, and the several placement areas correspond one-to-one with several holes on the tube sheet.

[0017] The present invention will be further described in detail below with reference to embodiments: like Figures 1-8 As shown, this utility model provides an anti-collision device suitable for ceramic fiber filter tubes, including a perforated plate 2 and an anti-collision component for separating adjacent ceramic fiber filter tube bodies 1. The anti-collision component is fixedly connected to the perforated plate 2, and the anti-collision component includes a placement area 7 corresponding to the plate hole 6 on the perforated plate 2. One end of the ceramic fiber filter tube body 1 passes through the plate hole 6 and is placed in the placement area 7. The other end of the ceramic fiber filter tube body 1 is fixedly connected to the perforated plate 2 through a filter tube flange. A limiting component for blocking the ceramic fiber filter tube body 1 is provided at the bottom of the placement area 7. The anti-collision component is made of corrosion-resistant and high-temperature resistant material.

[0018] Furthermore, the corrosion-resistant and high-temperature-resistant materials are stainless steel or non-metallic materials.

[0019] Furthermore, the material form of the anti-collision component is flat steel or round steel.

[0020] As one example, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the anti-collision component is a columnar anti-collision cage 3. The anti-collision cage 3 corresponds to the plate hole 6 of the tube sheet 2, and one end of the anti-collision cage 3 is fixedly connected to the plate hole 6 of the tube sheet 2. The placement area 7 is located in the inner cavity of the anti-collision cage 3. Steel mesh or steel strip can be welded on the anti-collision cage 3 so that each ceramic fiber filter tube 1 is independent and does not interfere with each other. In addition, once a ceramic fiber filter tube 1 breaks, the broken part falls a short distance and is blocked by the steel cage or steel frame, so that it will not continue to fall, and will not collide with the surrounding ceramic fiber filter tubes 1, causing them to be damaged or even broken, thus ensuring the stable operation of the equipment.

[0021] The upper part of the anti-collision cage 3 can be fixedly connected to the tube sheet 2 by welding, or directly fixed to the inside of the hole 6 of the tube sheet 2; and the number of anti-collision cages 3 is the same as the number of ceramic fiber filter tubes 1, so as to achieve one-to-one protection.

[0022] like Figure 1 As shown, the limiting component is a retaining ring 8, which is fixedly connected to the end of the anti-collision cage 3 away from the tube sheet 2. The design of the retaining ring 8 causes the bottom of the anti-collision cage 3 to be in a contracted state. Thus, when the ceramic fiber filter tube 1 breaks, the broken part falls a short distance and is blocked by the bottom contraction structure, preventing it from falling further.

[0023] Furthermore, the longitudinal cross-sectional shape of the anti-collision cage 3 is circular or square. The design of the cross-sectional shape of the anti-collision cage 3 being circular or square allows the anti-collision cage 3 to be adapted to ceramic fiber filter tubes 1 of different specifications.

[0024] As another embodiment, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the anti-collision assembly consists of at least two anti-collision frames 4 arranged in a crisscross pattern. Each anti-collision frame 4 is enclosed by a number of placement areas 7, i.e. square holes, by a crisscross support. The number of placement areas 7 corresponds one-to-one with the number of plate holes 6 on the tube sheet 2. The ends of the crisscross support of each anti-collision frame 4 are connected to the inner wall of the integrated desulfurization, denitrification and dust removal equipment. The connection technology can be operated using existing conventional technology, which will not be described in detail in this article.

[0025] like Figure 4As shown, in this embodiment, the anti-collision frame 4 is designed with five pieces, which are distributed at equal intervals from top to bottom to form a multi-layer square hole mesh. This ensures that each square hole of the anti-collision frame 4 corresponds to the ceramic fiber filter tube 1, so that the ceramic fiber filter tube 1 is isolated and does not interfere with each other. Moreover, steel mesh or steel strips can be welded between the multi-layer anti-collision frames 4 to ensure that when a ceramic fiber filter tube 1 breaks, the broken part falls a very short distance and is stopped by the steel cage or steel frame and the baffle 5, so that it will not continue to fall and will not collide with the surrounding ceramic fiber filter tubes 1. This ensures that the broken tube will not affect the surrounding filter tubes and guarantees the continuous and stable operation of the equipment.

[0026] Furthermore, such as Figure 4 As shown, the limiting component is a stop bar 5, and the stop bar 5 is connected to the placement area 7 of the bottom anti-collision frame 4. It should be noted that in this embodiment, the limiting component includes, but is not limited to, the stop bar 5, and may also be a stop bar or a stop block. Its function is to receive the broken filter tube part, prevent it from falling and colliding with the surrounding ceramic fiber filter tube body 1, and ensure the stable operation of the equipment.

[0027] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
