Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a deeply optimized tubular dust collector flushing water system. Background Technology

[0002] Tube bundle dust collectors and demisters are commonly used in the market for deep dust and mist removal after flue gas desulfurization in industrial furnaces and kilns. Their working principle involves high-speed rotation of saturated flue gas through internal separators, guide rings, and other components. Fine dust particles and droplets in the flue gas form a liquid film on the surfaces of the separator, guide rings, and support cylinder walls under centrifugal force, continuously capturing these particles. However, in some flue gas systems with low gas-liquid ratios and high dust content, gypsum structures easily form on the cylinder walls or separator surfaces. Especially between separator blades, where the gaps are small, dust buildup can clog the tube bundle dust collector and demister, causing it to lose its flow capacity and triggering a vicious cycle that ultimately affects the operating resistance of the absorption tower. Currently, the flushing water system of tube bundle dust collectors and demisters on the market typically consists of 11 nozzles arranged in sections (1+2+4+4), with all lower flushing water nozzles pointing downwards at a certain angle. However, the clogging of tubular dust and mist collectors is almost entirely concentrated at the bottom layer, with clogging in the middle and top layers being rare. The existing tubular dust and mist collectors use a 1+2+4+4 design with 11 nozzles evenly distributed, which is not adjusted according to the dust distribution and cannot effectively remove the clogging at the bottom layer of the tubular dust and mist collector.

[0003] Therefore, a deeply optimized tubular dust collector flushing water system is of positive significance. Summary of the Invention

The nozzle includes a first nozzle disposed at the top of the tube cap; two second nozzles arranged circumferentially in the middle of the second mounting member; three third nozzles arranged circumferentially on the top of the third mounting member; three fourth nozzles arranged circumferentially on the top of the fourth mounting member; and three fifth nozzles arranged circumferentially on the bottom of the fifth mounting member.

[0006] According to the technical solution provided in the embodiments of this application, the axial direction of the first nozzle is parallel to the vertical direction; the axial direction of the second nozzle is perpendicular to the vertical direction; the axial directions of the third nozzle and the fourth nozzle extend downward at an angle, and the third nozzle and the fourth nozzle form a first angle with the horizontal plane with the opening facing closer to the inside of the tube; the axial direction of the fifth nozzle extends upward at an angle, and the fifth nozzle forms a second angle with the horizontal plane with the opening facing away from the inside of the tube.

[0007] According to the technical solution provided in the embodiments of this application, the bottom of the pipe cover, the upper and lower ends of the first pipe, the upper and lower ends of the second pipe, the upper and lower ends of the third pipe, and the top of the water injection pipe are all provided with threaded grooves; the upper and lower ends of the second mounting component, the upper and lower ends of the third mounting component, the upper and lower ends of the fourth mounting component, and the upper and lower ends of the fifth mounting component are all provided with threads that fit with the threaded grooves.

[0008] According to the technical solution provided in the embodiments of this application, the pipe body is further provided with a connecting component, and the pipe body is detachably connected to the mounting component through the connecting component.

[0009] According to the technical solution provided in the embodiments of this application, the connecting assembly includes two connecting grooves arranged radially symmetrically about the pipe body. Each connecting groove is provided with a limiting rod, a connecting block is fitted on the limiting rod, and a spring is also fitted on the limiting rod. One end of the spring is connected to the connecting block, and the other end is connected to the groove wall of the connecting groove. A slot is opened at one end of the connecting block near the inside of the pipe body. Both the upper and lower ends of the mounting component are provided with locking blocks that fit into the slot. A waterproof plate for sealing the connecting groove is connected to the end of the connecting block away from the inside of the pipe body.

[0010] According to the technical solution provided in the embodiments of this application, the connecting groove is an arc-shaped through groove, the limiting rod is an arc-shaped rod, the slot is a cross-shaped through groove, and the waterproof plate is an arc-shaped plate.

Furthermore, the number of nozzles in this device is essentially the same as the traditional 1+2+4+4 (11 nozzles) flushing nozzles, ensuring consistent system water consumption and avoiding further increases in water costs. This device can have the same pipe length and nozzle fixing positions as traditional flushing water pipes, ensuring full compatibility with common tubular dust and demister flushing water pipes, greatly enhancing its practicality.

[0014] This invention also includes a connecting assembly. The locking block and cross-shaped slot in the connecting assembly enable quick connection and unlocking between the mounting component and the connecting assembly. Compared to using threaded grooves and threaded detachable connections, this allows for faster disassembly and installation, further improving installation speed, reducing downtime, and lowering maintenance costs and labor intensity. Furthermore, the spring absorbs and cancels out most of the vibration energy, significantly reducing the amplitude of vibration transmitted to the pipe body and nozzle. This effectively avoids the problem of loosening due to long-term vibration when using threaded connections, protects the nozzle from vibration damage, and significantly improves the reliability and lifespan of the system.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1-7 The present invention provides a deeply optimized flushing water system for a tube bundle dust collector, comprising: Pipe body 1 is a cylindrical water pipe, including a pipe cover 14, a first pipe body 11, a second pipe body 12, a third pipe body 13 and a water injection pipe 15 arranged vertically; Mounting component 3 includes a second mounting component 31 whose upper and lower ends are detachably connected to the bottom end of the pipe cover 14 and the top end of the first pipe 11, respectively; a third mounting component 32 whose upper and lower ends are detachably connected to the bottom end of the first pipe 11 and the top end of the second pipe 12, respectively; a fourth mounting component 33 whose upper and lower ends are detachably connected to the bottom end of the second pipe 12 and the top end of the third pipe 13, respectively; and a fifth mounting component 34 whose upper and lower ends are detachably connected to the bottom end of the third pipe 13 and the top end of the water injection pipe 15, respectively. Nozzle 2 includes a first nozzle 21 located at the top of the tube cover 14; two second nozzles 22 arranged circumferentially in the middle of the second mounting member 31; three third nozzles 23 arranged circumferentially on the top of the third mounting member 32; three fourth nozzles 24 arranged circumferentially on the top of the fourth mounting member 33; and three fifth nozzles 25 arranged circumferentially on the bottom of the fifth mounting member 34.

[0021] Water is injected into the pipe body 1 through the water injection pipe 15, and water is sprayed out from the nozzle 2 to rinse the cylinder wall or the surface of the separator of the tube bundle dust collector.

[0022] In this invention, the pipe body 1 adopts a segmented design and is connected by mounting parts 3. This modular structure makes the entire system easier to align and fix during installation. When maintenance or replacement of a part is required, only the local module can be disassembled without dismantling the entire system, greatly reducing maintenance difficulty and cost. At the same time, the vertically arranged cylindrical water pipe structure is stable and can withstand high water pressure, ensuring uniform and stable flushing water flow. The water injection pipe 15 supplies water to the entire system. The pipeline is simple and easy to control. The pipe cover 14 can prevent impurities from entering the system and makes the first nozzle 21 at the top function independently, improving the flushing at the top of the system. The detachable connection between the pipe body 1 and the mounting parts 3 provides high flexibility. The design allows for easy increase or decrease of the number of pipe bodies 1 and mounting parts 3 according to the actual height of the dust collector cylinder wall and flushing requirements. This design gives the system strong adaptability and scalability. The number of nozzles 2 in this device is 1, 2, 3, 3, and 3 from top to bottom. This device adopts a 1+2+3+3+3 structure, which increases the flushing force on the bottom of the tube bundle dust collector and demister, greatly reducing the possibility of blockage of the bottom separator. In addition, the number of nozzles 2 in this device is basically the same as the number of 11 nozzles in the traditional flushing water nozzle 1+2+4+4, ensuring the same water consumption of the system and avoiding further increase in water costs. This device can have the same pipe length 1 and fixed position of nozzle 2 as the traditional flushing water pipe, ensuring that this device is fully compatible with common tube bundle dust collector and demister flushing water pipes, greatly enhancing its practicality.

[0023] In some embodiments, the axial direction of the first nozzle 21 is parallel to the vertical direction; the axial direction of the second nozzle 22 is perpendicular to the vertical direction; the axial directions of the third nozzle 23 and the fourth nozzle 24 extend downward at an angle, and the third nozzle 23 and the fourth nozzle 24 form a first angle with the horizontal plane with the opening facing closer to the inside of the tube body 1; the axial direction of the fifth nozzle 25 extends upward at an angle, and the fifth nozzle 25 forms a second angle with the horizontal plane with the opening facing away from the inside of the tube body 1.

[0024] Furthermore, the first nozzle 21 is a hollow cone nozzle, while the second nozzle 22, the third nozzle 23, the fourth nozzle 24, and the fifth nozzle 25 are solid cone nozzles.

[0025] like Figures 1-5 As shown, the first nozzle 21 can spray upward flushing water and is a hollow cone nozzle. The water curtain sprayed from the first nozzle 21 is annular with a hollow center and coarser water droplets, which can cover a larger circular area. It is very suitable for covering a large space at the top of the system, and the relatively dispersed water curtain can pre-wet the area below, preparing for a powerful flush below. The second nozzle 22, the third nozzle 23, and the fourth nozzle 24 can spray downward flushing water, and the fifth nozzle 25 can spray upward flushing water. All of them are solid cone nozzles, which can concentrate the water flow energy into a solid cone, resulting in stronger impact and shearing force on the cylinder wall and better effect on removing adhesive dust. Furthermore, the second nozzle 22, the third nozzle 23, the fourth nozzle 24, and the fifth nozzle 25 work together to ensure that the flushing force on each unit area within the covered area is basically the same through multi-angle three-dimensional spraying, thoroughly eliminating the bottom edges and protrusion dead corners that may exist in traditional vertical flushing.

[0026] In some embodiments, the bottom of the pipe cover 14, the upper and lower ends of the first pipe 11, the upper and lower ends of the second pipe 12, the upper and lower ends of the third pipe 13, and the top of the water injection pipe 15 are all provided with threaded grooves; the upper and lower ends of the second mounting member 31, the upper and lower ends of the third mounting member 32, the upper and lower ends of the fourth mounting member 33, and the upper and lower ends of the fifth mounting member 34 are all provided with threads that fit the threaded grooves.

[0027] like Figures 1-5 As shown, the thread groove and thread style are uniform, which facilitates mass production and quality control. The thread groove and thread cooperate with each other to achieve quick disassembly. When a nozzle 2 or mounting part 3 needs to be inspected, cleaned or replaced, simply unscrew the mounting part 3 at that location. This achieves true local maintenance, shortens downtime, and reduces maintenance costs and labor intensity.

[0028] In some embodiments, the tube body 1 is further provided with a connecting component 5, and the tube body 1 is detachably connected to the mounting component 3 through the connecting component 5.

[0029] like Figure 5 and Figure 6 As shown, this embodiment uses connection component 5, which allows for faster disassembly and installation compared to using threaded grooves and threaded detachable connections, further improving installation speed, shortening downtime, and reducing maintenance costs and labor intensity.

[0030] In some embodiments, the connecting assembly 5 includes two connecting grooves 51 arranged radially symmetrically about the tube body 1. Each connecting groove 51 is provided with a limiting rod 52. A connecting block 54 is fitted on the limiting rod 52. A spring 53 is also fitted on the limiting rod 52. One end of the spring 53 is connected to the connecting block 54, and the other end is connected to the groove wall of the connecting groove 51. A slot 541 is opened at one end of the connecting block 54 near the inside of the tube body 1. Both the upper and lower ends of the mounting component 3 are provided with locking blocks 542 that fit into the slot 541. A waterproof plate 55 for sealing the connecting groove 51 is connected to one end of the connecting block 54 away from the inside of the tube body 1.

[0031] Furthermore, the connecting groove 51 is an arc-shaped through groove, the limiting rod 52 is an arc-shaped rod, the slot 541 is a cross-shaped through groove, and the waterproof plate 55 is an arc-shaped plate.

[0032] Furthermore, a first sealing groove is provided on the outer surface of the pipe body 1, and a protrusion corresponding to the first sealing groove is provided at one end of the waterproof plate 55 near the outer surface of the pipe body 1.

[0033] During installation, pull the connecting block 54, align the locking block 542 on the mounting piece 3 with the cross-shaped locking groove 541 on the connecting block 54, and release the connecting block 54. It will then automatically lock under the elastic force of the spring 53. Disassembly is performed by reversing the operation.

[0034] like Figure 5 and Figure 6As shown, the connecting block 54 can slide within the arc-shaped connecting groove 51 along the trajectory of the arc-shaped limiting rod 52. The spring 53 provides a restoring force. The locking block 542 and the cross-shaped locking groove 541 enable quick connection and unlocking between the mounting part 3 and the connecting assembly 5. The presence of the spring 53 makes the connecting block 54 (and the mounting part 3 and the pipe body 1 connected through it) no longer rigidly fixed. When the dust collector vibrates during operation, the spring 53 can absorb and cancel most of the vibration energy, greatly reducing the amplitude of vibration transmitted to the pipe body 1 and the nozzle 2. This effectively avoids the problem of loosening due to long-term vibration when using threaded connections, and also protects the nozzle 2 from vibration damage, significantly improving the reliability and lifespan of the system; and the spring 53 always exerts an outward pushing force on the connecting block 54, which is converted into a continuous clamping force on the mounting part 3 through the locking block 542, ensuring a firm connection and preventing shaking; the locking block 542 and the cross-shaped locking groove 541 lock together much faster than simply relying on the threaded groove and threaded locking, greatly simplifying the maintenance process and shortening downtime; the arc-shaped waterproof plate 55 fits perfectly with the cylindrical shape of the pipe body 1, has a good streamline, is not easy to accumulate dust or obstruct the falling of materials, and the first sealing groove and protrusion further enhance the waterproof and dustproof effect.

[0035] In some embodiments, the mounting component 3 is provided with a sealing ring 4 for closing the connection gap.

[0036] like Figures 1-7 As shown, the sealing ring 4 is installed on the nozzle mounting part 3 to seal the radial connection gap generated after the mounting part 3 is connected to the pipe body 1; the sealing ring 4 further improves the sealing performance of the device, ensuring that all water pressure from the water injection pipe 15 is effectively guided to the nozzle 2, thereby converting it into flushing water flow, avoiding pressure loss, and ensuring that each nozzle 2 has the spray force required by the design, so that the flushing effect reaches the expected level.

[0037] In some embodiments, the nozzle 2 is made by hot-melt welding and is a one-piece structure.

[0038] Nozzle 2 is made by hot-melt welding, which welds the nozzle core and nozzle body into a whole. This can effectively solve the problem that the nozzle core is easy to fall off when the flushing water nozzle 2 is installed upside down and under the action of water hammer.
