Description

Technical Field

[0001] This invention relates to the field of flue gas pretreatment technology, specifically to a flue gas settling treatment device and a waste incinerator. Background Technology

[0002] Waste incineration is a crucial method for the harmless, reduced-volume, and resource-based disposal of waste. However, the incineration process generates a large amount of flue gas. This flue gas contains various pollutants such as dust, acidic gases, heavy metals, and dioxins, making settling a vital step in flue gas purification. However, existing flue gas treatment equipment requires regular maintenance to maintain its effectiveness. This maintenance is extremely cumbersome and necessitates downtime, disrupting operational continuity.

[0003] To this end, Chinese Patent No. CN118543195B discloses a waste incineration flue gas pretreatment device. Its flue gas settling device employs a combination of water mist spraying and centrifugal separation to condense dust in the flue gas into larger dust particles. Then, through centrifugal force, the condensed dust is thoroughly separated from the flue gas, effectively removing dust and improving the pretreatment effect. The clever combination of the settling cylinder and the follow-up descaling device achieves a relative movement effect, allowing the follow-up descaling device to thoroughly remove dust adhering to the settling cylinder and enabling cyclical operation, effectively improving the dust removal efficiency in the flue gas.

[0004] However, most existing flue gas treatment devices remove adhering impurities by scraping with blades or other descaling structures. However, particulate matter in the flue gas combines with water mist and easily adheres to the inner wall of the flue gas treatment chamber. Traditional blades cannot completely remove the stubborn impurities that are damp and clump together. Summary of the Invention

[0011] Preferably, the rotary drive assembly includes a support, a rotary gear, and a spur gear; the support is disposed on a second mounting ring, and a rotary driver is provided on the support; the rotary gear is sleeved on the drive end of the rotary driver; the spur gear is sleeved on a third mounting ring, and the rotary gear and the spur gear are meshed together.

[0012] Preferably, the second mounting ring is provided with a protective shell, which cooperates with the second mounting ring to form a second cavity for accommodating the rotating gear and the spur gear.

[0013] Preferably, the movable seat is equipped with a two-way scraper that fits against the inner wall of the settling chamber.

[0014] Preferably, the second mounting ring is provided with a convex ring, which cooperates with the annular scraper to form a receiving groove for accommodating the scraped impurities; the end of the guide rod away from the first connecting ring is connected to a second connecting ring, which is connected to the second mounting ring; a discharge groove is provided at the bottom of the inner wall of the settling chamber, and when the second mounting ring moves down to the discharge groove, the impurities accumulated in the receiving groove fall down to the bottom plate along the discharge groove.

[0015] A waste incinerator includes a flue gas settling treatment device.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention achieves flue gas settling through a sprayer and utilizes the synergistic effect of annular scrapers and a vibration mechanism to enhance the cleaning of the inner wall, especially targeting stubborn impurities such as sticky oil dust and damp, clump-like dust. It achieves high-efficiency flue gas treatment and thorough cleaning of stubborn impurities on the inner wall, solving the problem of traditional scraper cleaning methods failing to completely remove sticky or clump-like impurities, leading to a thicker ash layer and affecting the operating efficiency of the device. During operation, the sprayer atomizes the flue gas, causing particles to settle. Loose dust adhering to the inner wall is directly scraped away by the annular scraper. Sticky oil dust, damp, clump-like dust, and other stubborn impurities are removed under the control mechanism: the lifting component drives the second mounting ring and scraper to move up and down along the inner wall, while the rotation drive component causes the third mounting ring to rotate the movable seat and vibration mechanism. The high-frequency vibration generated by the vibration mechanism is transmitted to the contact area between the scraper and the inner wall, causing stubborn impurities to detach from the inner wall under the vibration. Combined with the mechanical scraping of the scraper, these impurities are thoroughly removed, preventing residue buildup and ensuring long-term efficient operation of the settling chamber.

[0018] 2. This invention transmits the rotational power of the third mounting ring to the mounting shaft via a transmission assembly, causing the eccentric counterweight to rotate and vibrate. This synchronizes the vibration with the scraper's movement, improving the precision and continuity of vibration cleaning for stubborn impurities such as sticky oil dust and damp, clump-like dust. The scraper vibrates while scraping the inner wall up and down, creating a high-frequency peeling effect on sticky oil dust. Damp, clump-like dust is broken up and scraped away under the vibration, preventing stubborn impurities from remaining and further improving cleaning efficiency and thoroughness. Simultaneously, the power linkage reduces energy consumption and simplifies the device structure.

[0019] 3. This invention achieves stable rotation of the mounting shaft and eccentric counterweight when the movable drive seat rotates by the meshing transmission of the bevel gear and the protection of the sealed first cavity. During operation, the rotary drive assembly drives the third mounting ring to rotate. Due to the relative rotation of the second and third mounting rings, the bevel gear in the first cavity meshes with the bevel gear, causing the mounting shaft and eccentric counterweight to rotate and generate vibration. The sealed first cavity prevents flue gas and impurities from entering the transmission parts, ensuring precise and stable bevel gear meshing. The vibration is transmitted through the movable seat and the third mounting ring to the second mounting ring and the annular scraper, causing the scraper to vibrate continuously during the lifting and scraping process, effectively stripping away sticky oil dust, breaking up clumps of flue gas, and thoroughly removing it.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1-5 A flue gas settling treatment device includes a settling chamber 1, a cleaning mechanism 2, a vibration mechanism 3, and a control mechanism 4. The settling chamber 1 is provided with a first mounting ring 11, on which a sprayer 111 is mounted. The cleaning mechanism 2 includes a second mounting ring 21 and a third mounting ring 22. The second mounting ring 21 is tightly fitted to the inner wall of the settling chamber 1, and an annular scraper 211 for cleaning the inner wall of the settling chamber 1 is provided on the second mounting ring 21. The third mounting ring 22 is rotatably connected to the second mounting ring 21, and the axis of the third mounting ring 22 is collinear with the axis of the second mounting ring 21. A movable seat 221 is connected to the third mounting ring 22. The vibration mechanism 3 is mounted on the movable seat 221. The control mechanism 4 includes a lifting assembly 41 and a rotation drive assembly 42. The lifting assembly 41 is mounted on the settling chamber 1 and is used to control the second mounting ring 21 to rise and fall vertically. The rotation drive assembly 42 is mounted on the second mounting ring 21 and is used to drive the third mounting ring 22 to rotate.

[0033] This invention achieves flue gas settling through a sprayer 111 and enhances the cleaning of the inner wall through the synergistic effect of an annular scraper 211 and a vibration mechanism 3. It is particularly effective against stubborn impurities such as sticky oil dust and damp, clump-like dust, achieving high efficiency in flue gas treatment and thorough cleaning of stubborn impurities on the inner wall. This solves the problem of traditional scraper cleaning methods failing to completely remove sticky or clump-like impurities, leading to a thicker ash layer and affecting the operating efficiency of the device. The settling chamber 1 is equipped with an inlet pipe 12, an exhaust pipe 13, and an observation window 14. During the incineration of waste in a waste incinerator, the generated flue gas is input into the settling chamber 1 through the inlet pipe 12. Inside the settling chamber 1, particles in the flue gas combine with the water mist sprayed by the sprayer 111 and settle under gravity, completing the separation of coarse particles in the flue gas. The settling chamber 1 is equipped with an observation window 14 for convenient observation of the internal conditions by operators. During operation, the sprayer 111 sprays the flue gas, causing particles to settle. Loose dust adhering to the inner wall is directly scraped away by the annular scraper 211, while stubborn impurities such as sticky oil dust and damp, clumped dust are removed by the control mechanism 4: the lifting component 41 drives the second mounting ring 21 and the scraper to move up and down along the inner wall to scrape, while the rotation drive component 42 causes the third mounting ring 22 to drive the movable seat 221 and the vibration mechanism 3 to rotate. The high-frequency vibration generated by the vibration mechanism 3 is transmitted to the contact part between the scraper and the inner wall, causing stubborn impurities to detach from the inner wall adhesion under the action of vibration. Combined with the mechanical scraping of the scraper, the impurities are thoroughly removed, avoiding the accumulation of impurities and ensuring the long-term efficient operation of the settling chamber 1.

[0034] Reference Figure 4 , Figure 6 and Figure 7 The vibration mechanism 3 includes a mounting shaft 31 and a transmission assembly 32. The mounting shaft 31 is rotatably mounted on the movable seat 221, and an eccentric weight 311 is fixedly sleeved on the mounting shaft 31. The mounting shaft 31 is connected to the second mounting ring 21 through the transmission assembly 32. When the rotation drive assembly 42 drives the third mounting ring 22 to rotate, the transmission assembly 32 drives the mounting shaft 31 to rotate.

[0035] This invention transmits the rotational power of the third mounting ring 22 to the mounting shaft 31 via the transmission component 32, causing the eccentric weight 311 to rotate and vibrate. This achieves synchronous linkage between vibration and scraper action, improving the accuracy and continuity of vibration cleaning for stubborn impurities such as sticky oil dust and damp, clump-like dust. During operation, the rotation drive component 42 drives the third mounting ring 22 to rotate, which in turn drives the mounting shaft 31 and the eccentric weight 311 to rotate via the transmission component 32. The rotation of the eccentric weight 311 generates periodic centrifugal force, causing the movable seat 221 and the third mounting ring 22 to vibrate. This vibration is transmitted to the second mounting ring 21 and the annular scraper 211. At this time, the lifting component 41 drives the second mounting ring 21 to rise and fall. The scraper vibrates while scraping the inner wall up and down, creating a high-frequency peeling effect on sticky oil dust. Damp, clump-like dust is broken up and scraped away under vibration, preventing stubborn impurities from remaining and further improving cleaning efficiency and thoroughness. Simultaneously, the power linkage reduces energy consumption and simplifies the device structure.

[0036] Reference Figure 3 and Figure 10 The transmission assembly 32 includes a bevel ring 321 and a bevel gear 322; the second mounting ring 21 and the third mounting ring 22 are tightly fitted together to form a sealed first cavity, the bevel ring 321 is mounted on the second mounting ring 21 and is located in the first cavity; the bevel gear 322 is sleeved on the mounting shaft 31, and the bevel ring 321 and the bevel gear 322 are meshed together.

[0037] This invention achieves stable rotation of the mounting shaft 31 and eccentric weight 311 when the drive seat 221 rotates by the meshing transmission of the bevel ring 321 and the bevel gear 322 and the protection of the sealed first cavity. During operation, the rotary drive assembly 42 drives the third mounting ring 22 to rotate. Due to the relative rotation of the second mounting ring 21 and the third mounting ring 22, the bevel ring 321 and the bevel gear 322 in the first cavity mesh, causing the mounting shaft 31 and the eccentric weight 311 to rotate and generate vibration. The sealed first cavity prevents flue gas and impurities from entering the transmission part, ensuring accurate and stable bevel gear meshing. The vibration is transmitted to the second mounting ring 21 and the annular scraper 211 through the movable seat 221 and the third mounting ring 22, causing the scraper to vibrate continuously during the lifting and scraping process, effectively stripping away sticky oil dust, breaking up clumps of flue gas and dust and thoroughly removing them, further improving the device's ability to clean complex impurities and its operational reliability.

[0038] Reference Figure 1 and Figure 2 The settling chamber 1 is provided with a top plate 15 and a bottom plate 16 on its upper and lower sides, respectively; a connecting frame 161 is provided on the bottom plate 16, and the top plate 15 is connected to the connecting frame 161; both the top plate 15 and the bottom plate 16 are provided with rubber rings 17 for connecting with the settling chamber 1.

[0039] This invention strengthens the structural stability of the settling chamber 1 through the top plate 15, bottom plate 16 and connecting frame 161, and uses rubber ring 17 to specifically absorb the vibration generated by the vibration mechanism 3 to achieve vibration isolation. For the treatment of flue gas containing sticky oil dust and moist clumps of smoke, this invention not only avoids the impact of vibration on other mechanical structures, but also ensures the overall operational stability of the device. It solves the technical problem that the vibration of the vibration mechanism 3 is transmitted to other components, causing structural loosening and wear, which affects the service life and operational accuracy of the device. During operation, the flue gas treated by the sprayer 111 settles in the settling chamber 1. When the cleaning mechanism 2 is activated and the vibration mechanism 3 generates vibration to assist in the removal of sticky oil dust and agglomerated dust, the rubber ring 17 absorbs most of the vibration energy through its own elastic deformation, preventing the vibration from being transmitted to other mechanical structures such as the top plate 15, bottom plate 16, and connecting frame 161. This avoids problems such as increased transmission gaps and decreased positioning accuracy in precision components such as the lifting assembly 41 and rotary drive assembly 42 of the control mechanism 4 due to vibration. At the same time, it prevents fatigue damage to the supporting structure such as the connecting frame 161 due to long-term vibration, so that the vibration only acts on the cleaning mechanism 2 and the inner wall of the settling chamber 1 to enhance the cleaning effect. This ensures that the overall structure of the device is stable and reliable during long-term treatment of flue gas containing stubborn impurities, thus extending its service life.

[0040] Reference Figure 2 and Figure 5 The lifting assembly 41 includes a linear driver 411, a first connecting ring 412, and a guide rod 413. The linear driver 411 is mounted on the connecting frame 161. The first connecting ring 412 is connected to the driving end of the linear driver 411. The guide rod 413 is connected to the first connecting ring 412, and the guide rod 413 is connected to the second mounting ring 21 via a transmission connection. The first connecting ring 412 drives the second mounting ring 21 to rise and fall through the guide rod 413.

[0041] This invention utilizes a lifting assembly 41 composed of a linear actuator 411, a first connecting ring 412, and a guide rod 413 to achieve smooth lifting of the second mounting ring 21. This ensures that the annular scraper 211, with vibration assistance, evenly adheres to the inner wall to clean stubborn impurities such as sticky oil dust and damp, agglomerated smoke generated during waste incineration. Simultaneously, the observation window 14 allows for direct monitoring of the internal conditions, solving the technical problems of uneven scraper adhesion, incomplete cleaning, and difficulty in monitoring internal working conditions caused by unstable lifting drive. During operation, the flue gas generated by waste incineration enters the settling chamber 1 through the inlet pipe 12. The sprayer 111 on the first mounting ring 11 sprays the flue gas to promote particle settling. Operators can directly observe the internal flue gas treatment and impurity adhesion through the observation window 14. When it is necessary to clean the impurities on the inner wall, the linear actuator 411 is activated, driving the first connecting ring 412 to rise and fall through the drive end. The first connecting ring 412 transmits power through the guide rod 413, causing the second mounting ring 21 to rise and fall smoothly along the inner wall of the settling chamber 1, ensuring that the annular scraper 211 is in uniform contact with the inner wall. At this time, the vibration generated by the vibration mechanism 3 is transmitted to the second mounting ring 21 through the third mounting ring 22. The scraper moves up and down with vibration, forming a continuous peeling force on the sticky oil dust, breaking up the damp and clump of soot and scraping it off completely. At the same time, the rubber ring 17 absorbs the vibration to prevent it from affecting the linear actuator 411 and other components. The guide rod 413 ensures the verticality of the second mounting ring 21 when it rises and falls, preventing the scraper from wearing off-center, further improving the cleaning effect on stubborn impurities in the waste incineration flue gas and the stability of the device operation.

[0042] Reference Figure 4 , Figure 8 and Figure 9 The rotary drive assembly 42 includes a support 421, a rotary gear 422, and a spur gear 423. The support 421 is mounted on the second mounting ring 21, and a rotary driver 4211 is mounted on the support 421. The rotary gear 422 is sleeved on the drive end of the rotary driver 4211. The spur gear 423 is sleeved on the third mounting ring 22, and the rotary gear 422 and the spur gear 423 are meshed together.

[0043] This invention utilizes a rotary drive assembly 42, composed of a support 421, a rotary driver 4211, a rotary gear 422, and a spur gear 423, to achieve precise rotation of the third mounting ring 22. This ensures that the vibration mechanism 3 and the annular scraper 211 perform a three-dimensional cleaning action involving rotation, vibration, and scraping, addressing the problems of poor coordination in cleaning actions and the residue of stubborn impurities caused by unstable rotary drive. During operation, the flue gas from waste incineration enters the settling chamber 1 through the inlet pipe 12, and the sprayer 111 sprays to promote settling. Operators can observe the internal conditions through the observation window 14. During cleaning, the rotary drive 4211 is activated, driving the rotary gear 422 to rotate. The rotary gear 422 drives the spur gear 423 and the third mounting ring 22 to rotate through meshing with the spur gear 423, causing the movable seat 221 and the vibration mechanism 3 to rotate synchronously. At the same time, the lifting component 41 drives the second mounting ring 21 and the annular scraper 211 to rise and fall. The vibration generated by the vibration mechanism 3 is transmitted to the scraper, forming an up-and-down vibration scraping action in the rotating state, which peels off the sticky oil dust adhering to the inner wall in all directions. The damp and clump-like smoke dust is broken up and thoroughly scraped off in the rotational vibration. The precise transmission of gear meshing ensures the coordination of rotation, lifting, and vibration actions, further improving the cleaning efficiency of complex impurities in waste incineration flue gas.

[0044] Reference Figure 8 The second mounting ring 21 is provided with a protective shell 424, which cooperates with the second mounting ring 21 to form a second cavity for accommodating the rotating gear 422 and the spur gear 423.

[0045] This invention protects the rotating gear 422 and the spur gear 423 through a second cavity formed by the protective shell 424 and the second mounting ring 21. This addresses the issue of sticky oil dust and moist, agglomerated dust in waste incineration flue gas, preventing contamination of the gear transmission components and ensuring the long-term stable operation of the rotating drive assembly 42. It solves the technical problems of gear contamination leading to transmission failure, affecting vibration, and hindering the cleaning effect of scraping. In operation, waste incineration flue gas enters the settling chamber 1 through the inlet pipe 12. Particles in the flue gas are promoted to settle by water mist sprayed from the sprayer 111, and the operator observes through the observation window 14. During cleaning, the second chamber prevents fumes and impurities from entering the gear transmission area. The rotary drive 4211 drives the third mounting ring 22 to rotate through the meshing of the rotary gear 422 and the spur gear 423, which in turn drives the vibration mechanism 3 to rotate synchronously. At the same time, the lifting component 41 drives the second mounting ring 21 and the scraper to rise and fall. The vibration generated by the vibration mechanism 3 is transmitted to the scraper, which vibrates and scrapes the inner wall up and down in the rotating state. The second chamber ensures that the gears are always in a clean meshing state, avoiding the gear jamming caused by sticky oil dust. It ensures the precise coordination of rotation, lifting, and vibration, continuously and efficiently peeling off and removing sticky oil dust and clumps of fumes, further extending the service life and maintenance cycle of the device.

[0046] Reference Figure 6 , Figure 7 and Figure 10 The movable seat 221 is equipped with a bidirectional scraper 222 that fits against the inner wall of the settling chamber 1.

[0047] This invention combines the bidirectional scraper 222 on the movable seat 221 with vibration and rotation to achieve all-round and uniform cleaning of stubborn impurities such as sticky oil dust and damp clumps of smoke generated by waste incineration, solving the technical problems of dead corners and impurity residues in single scraper cleaning. During operation, the waste incineration flue gas enters the settling chamber 1 through the inlet pipe 12. The sprayer 111 sprays to promote settling, and the operator observes the internal situation through the observation window 14. During cleaning, the rotary drive assembly 42 drives the third mounting ring 22 to rotate the movable seat 221, causing the bidirectional scraper 222 to rotate along the circumference of the inner wall. At the same time, the vibration mechanism 3 drives the bidirectional scraper 222 to vibrate. In conjunction with the lifting assembly 41, the second mounting ring 21 and the annular scraper 211 move up and down. Under the dual action of vibration and rotation, the bidirectional scraper 222 peels off the sticky oil dust adhering to the inner wall from multiple directions, and thoroughly scrapes away the damp and clumps of flue gas after breaking them up. It effectively cleans the corner areas that are difficult for the annular scraper 211 to reach, ensuring that the impurities on the inner wall of the settling chamber 1 are evenly removed, and further improving the device's ability to handle complex flue gas impurities.

[0048] Reference Figure 6 and Figure 7 The second mounting ring 21 is provided with a protruding ring 212, which and the annular scraper 211 cooperate to form a receiving groove for receiving scraped impurities; the guide rod 413 is connected to a second connecting ring 414 at the end away from the first connecting ring 412, and the second connecting ring 414 is connected to the second mounting ring 21; a discharge groove is provided at the bottom of the inner wall of the settling chamber 1. When the second mounting ring 21 moves down to the discharge groove, the impurities accumulated in the receiving groove fall down to the bottom plate 16 along the discharge groove.

[0049] This invention utilizes a receiving groove formed by a convex ring 212 and an annular scraper 211 to accommodate scraped impurities, and works in conjunction with a discharge chute to centrally discharge the impurities. It addresses the technical problems of difficult impurity collection and secondary pollution caused by sticky oil dust and damp, clump-like smoke generated during waste incineration. During operation, waste incineration flue gas enters the settling chamber 1 through the inlet pipe 12. A sprayer 111 promotes particle settling, and operators observe the internal conditions through the observation window 14. During the cleaning process, the annular scraper 211, through the combined action of vibration, rotation, and lifting, scrapes off the sticky oil dust and damp, clump-like smoke from the inner wall. The impurities, under the influence of gravity and the scraper's thrust, temporarily enter the receiving groove formed by the convex ring 212 and the annular scraper 211. The linear actuator 411 drives the first connecting ring 412 to move downward. The first connecting ring 412 drives the second connecting ring 414 to move via the guide rod 413. The second connecting ring 414 drives the second mounting ring 21 to move. When the second mounting ring 21 moves downward to the discharge chute under the drive of the lifting component 41, the receiving chute corresponds to the discharge chute. The impurities accumulated in the chute fall onto the bottom plate 16 along the discharge chute, realizing the centralized collection and treatment of impurities, avoiding the scattering and residue of impurities in the device, and further improving the device's cleaning efficiency and environmental friendliness in waste incineration flue gas.

[0050] Reference Figures 1-10 A waste incinerator, including a flue gas settling treatment device.

[0051] This invention achieves synergistic operation of waste incineration and flue gas treatment, enabling efficient settling and convenient cleaning of complex flue gas impurities generated during incineration. It solves the technical problems of low flue gas treatment efficiency and difficult maintenance in traditional incinerators. Its structure includes a waste incineration body and a flue gas settling and treatment device connected to it. During operation, the flue gas generated by the combustion of waste in the incinerator enters the settling chamber 1 through pipes. The sprayer 111 in the settling chamber 1 sprays the flue gas, causing particulate impurities to settle and adhere to the inner wall. When the impurities accumulate to a certain level, the control mechanism 4 initiates the cleaning process: the lifting assembly 41 moves the second mounting ring 21 up and down along the inner wall; the rotation drive assembly 42 drives the third mounting ring 22 and the movable seat 221 to rotate; and the vibration mechanism 3 drives the scraper and bidirectional scraper 222 to vibrate, cleaning the sticky oil dust and agglomerated dust from multiple dimensions. The cleaned impurities are temporarily stored in the receiving groove formed by the convex ring 212 and the annular scraper 211. When the second mounting ring 21 moves down to the discharge chute, the impurities fall along the discharge chute to the bottom plate 16 for centralized treatment. Throughout the process, the observation window 14 allows real-time monitoring of the internal situation. The protective structure ensures stable operation of all transmission components, and the rubber ring 17 absorbs vibration, enabling the waste incinerator to efficiently process waste while achieving deep purification of the flue gas and long-term stable operation of the treatment system.
