Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal purification of boiler flue gas, and specifically, to a boiler flue gas de-blue treatment system based on multi-stage collaborative treatment. Background Art

[0002] With the development of industry, the problem of flue gas pollution generated by high-energy-consuming industries such as metal smelting has become increasingly serious. When the boiler burns insufficiently, the unburned oil combines with dust to form a blue plume, which not only violates relevant environmental protection regulations but may also lead to equipment oil accumulation, fire risks, and environmental pollution. The comprehensive treatment project of boiler flue gas de-blue belongs to the field of environmental engineering and is specifically classified as the direction of air pollution control engineering. Its core is to solve the atmospheric environmental problems caused by pollutant emissions in industrial boiler flue gas through technical means.

[0003] Existing flue gas treatment often involves primary separation. After the dust-containing flue gas enters through the air inlet of the cyclone tower, a high-speed swirl is formed under the action of the swirl plate, and large oil droplets, dust, and gas are separated by centrifugal force. Then comes secondary filtration. The gas treated by the cyclone tower enters the cartridge filter, and micron-sized dust and oily particles are captured through physical interception on the surface of the cartridge.

[0004] In the primary separation stage, the current centrifugal purification equipment faces several challenges. First, when the flue gas enters from the bottom of the equipment and undergoes centrifugal acceleration and rises, the flue gas particles near the acceleration zone are more easily separated due to the strong centrifugal force. However, for the flue gas above the acceleration zone, due to insufficient centrifugal force, its separation efficiency is low, resulting in a significant centrifugal force gradient stratification phenomenon. In addition, considering the limited height of the equipment and the continuous input of flue gas, and the fact that the flue gas forms a vortex after acceleration, the residence time of the flue gas in the device is short and not sufficient to complete the full centrifugal separation process, which further exacerbates the problem of incomplete separation. This situation not only affects the overall purification effect of the equipment but also limits the improvement of its processing capacity.

[0005] Based on this, the present invention discloses a boiler flue gas de-blue treatment system based on multi-stage collaborative treatment. Summary of the Invention

[0006] To solve the problem in the background art that in the primary separation stage of the centrifugal purification equipment, due to the centrifugal force gradient stratification formed after the flue gas enters and the insufficient residence time caused by the limited height of the equipment, the particulate matter in the flue gas cannot be fully separated, affecting the overall purification effect, the present invention provides a boiler flue gas de-blue treatment system based on multi-stage collaborative treatment, which includes a centrifugal furnace and a collection furnace arranged under the centrifugal furnace. An oil droplet collection device and a driving motor are arranged in the collection furnace, and the flue gas enters from the bottom of the centrifugal furnace.

[0007] Since the flue gas entering the centrifugal furnace is centrifugally accelerated, a centrifugal force gradient stratification occurs from bottom to top in the centrifugal furnace, resulting in a problem of different separation effects;

[0008] As a further improvement of this technical solution, a number of partition plates are evenly arranged in the centrifugal furnace. The partition plates divide the centrifugal furnace into several separation chambers. At the same time, at the bottom of each separation chamber, that is, above the partition plate, there is an eddy current fan driven by a driving motor. Among them, the output end of the driving motor is provided with a driving rod. The driving rod passes through several partition plates and a delay component and is connected to the eddy current fan corresponding to each separation chamber, and the driving rod extends into the delay component located at the top.

[0009] In this solution, since the flue gas in each separation chamber will form an eddy current after being accelerated, and the centrifugal furnace is divided into several separation chambers by partition plates, further shortening the height of the separation area. Therefore, in order to increase the residence time of the flue gas in the separation chamber and further improve the separation effect of the flue gas in the separation chamber;

[0010] As a further improvement of this technical solution, the partition plate is in a positive conical structure, and a delay component is arranged at the center position of the partition plate. The delay component is in a conical structure opposite to the partition plate.

[0011] On this basis, in order to allow the air in the axial region of the centrifugal furnace to escape smoothly through the delay component into the next separation chamber for separation, at the same time, it is necessary to meet the above-mentioned requirement of increasing the residence time of the flue gas in the separation chamber, and at the same time, to accelerate the rotation of the flue gas entering the next separation chamber in advance;

[0012] As a further improvement of this technical solution, the delay component includes a conveying cylinder. A spiral pushing blade is arranged in the conveying cylinder. The spiral pushing blade is fixed on the driving rod. The conveying cylinder is connected to the driving rod through the spiral pushing blade. The conveying cylinder is in a cylindrical structure. A delay cover is arranged at the top of the conveying cylinder. The delay cover is in a conical structure opposite to the partition plate structure. The bottom of the delay cover is communicated with the conveying cylinder.

[0013] In another solution, since the oil droplets in the flue gas after centrifugation will accumulate on the inner wall of the centrifugal furnace and scatter on the surface of the partition plate, the accumulated oil droplets need to be timely processed and collected to prevent affecting the subsequent purification effect;

[0014] As a further improvement of this technical solution, the top of the delay cover extends outside the top of the partition plate and leaves a gap with the top of the partition plate; a scraping component for scraping the oil droplets accumulated on the surface of the partition plate driven by the eddy current in the separation chamber is slidably arranged inside the top of the center of the partition plate; a blocking cover is fixed on the top of the delay cover. The center of the blocking cover is communicated with the top of the delay cover. The blocking cover is in a sleeve structure around the top of the delay cover.

[0015] As a further improvement of the technical solution, a chute is provided on the inner wall of the top end of the partition plate. The oil scraping assembly includes a slider slidably connected in the chute. A connecting rod is fixed on the slider. The upper and lower ends of the connecting rod are respectively arranged adjacent to the upper and lower surfaces of the partition plate. An installation rod is fixed at the upper end of the connecting rod. A scraping plate is fixed at the bottom of the installation rod. A driving fan blade is fixed at the bottom end of the connecting rod. The scraping plate is arranged perpendicular to the upper surface of the partition plate, and the bottom of the scraping plate is adapted to and fits the structure of the upper surface of the partition plate. The bottom of the scraping plate is made of rubber material and consists of several rubber strips. The driving fan blade is in an arc structure along the radial direction of the partition plate. The height of the driving fan blade gradually decreases from the center to the periphery, and the end of the driving fan blade adjacent to the periphery of the partition plate is lower than the height of the partition plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the boiler flue gas de-blue treatment system based on multi-stage collaborative processing, by arranging a partition plate to divide the centrifugal furnace into multiple separation chambers and configuring eddy fans at the bottom of each separation chamber, the flue gas entering the centrifugal furnace can continuously obtain additional centrifugal acceleration compensation during the ascending process layer by layer, thereby ensuring the full separation of particulate matter and effectively overcoming the problem of incomplete separation caused by the centrifugal force gradient stratification, and improving the overall purification efficiency.

[0018] 2. In the boiler flue gas de-blue treatment system based on multi-stage collaborative processing, the cooperation between the positive conical partition plate structure and the delay component not only adapts to the eddy current form after acceleration but also increases the residence time of the flue gas in the separation chamber, further improving the separation effect, enabling the flue gas near the axis position to pass through the delay component preferentially for more refined screening and then enter the next layer of separation, ensuring the high efficiency and comprehensiveness of the purification process.

[0019] 3. In the boiler flue gas de-blue treatment system based on multi-stage collaborative processing, the delay component composed of a spiral pushing blade and a delay cover not only increases the stay time of the flue gas in the current separation chamber but also prepares for the flue gas to accelerate and rotate in advance, enhancing the eddy current effect in the next separation chamber, which helps to compensate for part of the centrifugal force lost due to passing through the delay cover and ensures that the flue gas in each layer can maintain a high separation efficiency.

[0020] 4. In the boiler flue gas de-blue treatment system based on multi-stage collaborative processing, the design of the oil scraping assembly solves the problem that the accumulation of oil droplets affects the purification effect during long-term operation. The oil scraping assembly can be driven by the eddy current formed in the separation chamber to automatically remove the oil droplets accumulated on the surface of the partition plate, preventing it from interfering with the subsequent separation process and ensuring the continuous and efficient operation of the system.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In the primary separation stage of the existing centrifugal purification equipment, due to the centrifugal force gradient stratification formed after the flue gas enters and the insufficient residence time caused by the equipment height limitation, the particulate matter in the flue gas cannot be fully separated, affecting the overall purification effect.

[0034] Therefore, the present invention provides a boiler flue gas de-blue treatment system based on multi-stage collaborative processing. See Figures 1 - 2As shown in the figure, it includes a centrifugal furnace 1 and a collection furnace 2 arranged under the centrifugal furnace 1. An oil droplet collection device and a driving motor 4 are arranged in the collection furnace 2, and the flue gas enters from the bottom of the centrifugal furnace 1.

[0035] Since the flue gas entering the centrifugal furnace 1 is centrifugally accelerated, a centrifugal force gradient stratification occurs from bottom to top in the centrifugal furnace 1, resulting in a problem of different separation effects. In the present invention, a number of partition plates 7 are evenly arranged in the centrifugal furnace 1. The partition plates 7 divide the centrifugal furnace 1 into several separation chambers 3. At the same time, at the bottom of each separation chamber 3, that is, above the partition plate 7, there is an eddy current fan 6 driven by the driving motor 4. Among them, the output end of the driving motor 4 is provided with a driving rod 5. The driving rod 5 passes through a number of partition plates 7 and a delay component 11 and is connected to the eddy current fan 6 corresponding to each separation chamber 3, and the driving rod 5 extends into the delay component 11 located at the top.

[0036] During operation, after the flue gas enters from the bottom of the centrifugal furnace 1, it is centrifugally accelerated in the bottom separation chamber 3, and the formed eddy current starts to rise. The flue gas that has not been separated in the separation chamber 3 enters the second-layer separation chamber 3, and is further accelerated by the eddy current fan 6 in the bottom of the second-layer separation chamber 3, so that the originally lost centrifugal acceleration is further supplemented. Then, the flue gas in this area is separated again. In this way, it flows upward step by step and is separated and accelerated in multiple layers to ensure the separation effect. Finally, the flue gas that has separated large particle oil droplets enters the next link for purification.

[0037] Further, referring to Figures 2 - 4 As shown in the figure, since the flue gas in each separation chamber 3 will form an eddy current after being accelerated, and the centrifugal furnace 1 is divided into several separation chambers 3 by the partition plates 7, further shortening the height of the separation area. Therefore, in order to increase the residence time of the flue gas in the separation chamber 3 and further improve the separation effect of the flue gas in the separation chamber 3, in the present invention, the partition plate 7 has a positive conical structure, and a delay component 11 is arranged at the central position of the partition plate 7. The delay component 11 has a conical structure opposite to that of the partition plate 7.

[0038] During operation, after the flue gas enters the separation chamber 3 and forms a vortex after being accelerated by the vortex fan 6, the airflow will gradually form a conical structure and tend to increase upward. Therefore, the conical structure of the partition plate 7 is adapted to the accelerated vortex, so that the top of the partition plate 7 blocks the top of the vortex. The blocked vortex sinks and is accelerated and rotated again, thereby further separating the flue gas. With the continuous replenishment of the subsequent flue gas, the purification degree of the flue gas near the axis of the centrifugal furnace 1 is higher than that of the flue gas far from the axis. Therefore, the flue gas near the center can escape through the delay component 11 and enter the next separation chamber 3 for further centrifugal separation; that is to say, through the series design of multiple separation chambers 3 and the linkage of the driving rod 5 to each layer of vortex fans 6, the step-by-step centrifugal acceleration compensation is realized. When the flue gas is accelerated by the bottom vortex fan 6, the vortex fan 6 in the upper separation chamber 3 can re-strengthen the attenuated centrifugal force; this gradient enhancement mechanism effectively alleviates the separation efficiency stratification phenomenon caused by the attenuation of the centrifugal force field in the traditional device, and the particulate matter classification capture efficiency is increased by about 40%.

[0039] Specifically, referring to Figure 6 shown, in order to enable the air in the axial region of the centrifugal furnace 1 to smoothly escape through the delay component 11 into the next separation chamber 3 for separation, while also meeting the above requirements of increasing the residence time of the flue gas in the separation chamber 3 and accelerating the rotation of the flue gas entering the next separation chamber 3 in advance to improve the vortex effect of the flue gas in the next separation chamber 3, the present invention adopts the delay component 11 including a conveying cylinder 111. A spiral pushing blade 112 is arranged in the conveying cylinder 111. The spiral pushing blade 112 is fixedly arranged on the driving rod 5. The conveying cylinder 111 is connected to the driving rod 5 through the spiral pushing blade 112. The conveying cylinder 111 has a cylindrical structure. A delay cover 113 is arranged at the top of the conveying cylinder 111. The delay cover 113 has a conical structure opposite to the structure of the partition plate 7. The bottom of the delay cover 113 is communicated with the conveying cylinder 111.

[0040] During operation, the flue gas accelerated to form a vortex rotates and separates in the separation chamber 3. The structure of the delay cover 113 is adapted to the structure of the partition plate 7, as Figure 6 shown, an annular V-shaped separation zone is formed between the delay cover 113 and the partition plate 7. In this way, through this V-shaped separation zone, the residence time of the flue gas can be increased, and at the same time, more separation space can be provided for the flue gas. Moreover, combined with the inverted conical structure of the extension of the delay cover 113, the flue gas at the bottom and the inner circle can be screened, so that this part of the flue gas can enter the next separation chamber 3 first;

[0041] Since the flue gas in this part is relatively thin, and after passing through the retarder 113, that is, the flue gas entering the next separation chamber 3 from the central area of the partition plate 7 loses part of its centrifugal force under the obstruction of the retarder 113. Therefore, the design of the spiral pusher 112 enables the flue gas near the central area to be sent into the retarder 113 in portions through the spiral pusher 112. And in cooperation with the rotation of the spiral pusher 112 and the retarder 113 along with the driving rod 5, it compensates for the loss of centrifugal force of the flue gas caused by the retarder 113 originally, so that the centrifugal force of the flue gas entering the next separation chamber 3 is still relatively large. Then, in cooperation with the eddy current fan 6 in the next separation chamber 3 for acceleration, the effect of gradually increasing centrifugal force will be obtained. Then, finally, the separation effect of the flue gas escaping through the top separation chamber 3 will be better than that of the traditional one.

[0042] It should be noted that in order to increase the residence time and separation effect of the flue gas in the separation chamber 3, the height of the retarder 113 is higher than that of the partition plate 7. In this way, the internal purification effect of the flue gas after forming the eddy current is higher than that of the external, and at the same time, the purification effect of the bottom flue gas is better due to being close to the acceleration area of the eddy current fan 6, so the purification effect of the bottom flue gas is naturally higher than that of the top. Therefore, by making the height of the retarder 113 higher than that of the partition plate 7, the part of the gas with better purification effect enters the next separation chamber 3 first, and the remaining flue gas is further separated in the original separation chamber 3. In this way, not only the separation effect is improved hierarchically, but also the separation effect is further improved in the original separation chamber 3, providing multiple guarantees for the separation of the flue gas.

[0043] Furthermore, referring to Figures 6 - 7 As shown, since the oil droplets in the flue gas after centrifugation will accumulate on the inner wall of the centrifugal furnace 1 and scatter on the surface of the partition plate 7, the accumulated oil droplets need to be processed and collected in time to prevent affecting the subsequent purification effect. Therefore, the top of the retarder 113 extends outside the top of the partition plate 7 and leaves a gap with the top of the partition plate 7. This provides space for the rotation of the retarder 113. Secondly, a scraping oil assembly 10 for scraping the oil droplets accumulated on the surface of the partition plate 7 driven by the eddy current in the separation chamber 3 is slidably arranged inside the top of the center of the partition plate 7. In this way, when the scraping oil assembly 10 needs to rotate and work, the top of the retarder 113 can also provide the rotation space for the scraping oil assembly 10; and since there is a gap between the top of the retarder 113 and the partition plate 7, in order to reduce the escape of the flue gas from the gap rather than from inside the retarder 113, a blocking cover 12 is fixedly arranged on the top of the retarder 113. The center of the blocking cover 12 is connected to the top of the retarder 113, and the blocking cover 12 is in a sleeve structure around the top of the retarder 113; after such a setting, referring to Figure 6 It can be seen that the sleeve - type blocking cover 12 can block the gap between the retarder 113 and the partition plate 7, reducing the escape of the flue gas from here.

[0044] Among them, a chute 9 is provided on the inner wall of the top end of the partition plate 7. The oil scraping assembly 10 includes a slider 101 slidably connected in the chute 9. A connecting rod 102 is fixed on the slider 101. The upper and lower ends of the connecting rod 102 are respectively arranged adjacent to the upper and lower surfaces of the partition plate 7. An installation rod 103 is fixed at the upper end of the connecting rod 102. A scraping plate 104 is fixed at the bottom of the installation rod 103. A driving fan blade 105 is fixed at the bottom end of the connecting rod 102. The scraping plate 104 is arranged perpendicular to the upper surface of the partition plate 7, and the bottom of the scraping plate 104 is adapted to and fits the structure of the upper surface of the partition plate 7. The bottom of the scraping plate 104 is made of rubber and consists of several rubber strips. The driving fan blade 105 is in an arc structure along the radial direction of the partition plate 7. The height of the driving fan blade 105 gradually decreases from the center to the periphery, and the end of the driving fan blade 105 adjacent to the periphery of the partition plate 7 is lower than the height of the partition plate 7.

[0045] During operation, the eddy current in the separation chamber 3 will impact the driving fan blade 105, causing the driving fan blade 105 to rotate. Due to the arc structure of the driving fan blade 105, a better propulsion force will be obtained to drive the driving fan blade 105 to rotate. In order not to affect the separation effect of the flue gas in the area near the inner wall of the centrifugal furnace 1, the driving fan blade 105 is located near the inner wall of the centrifugal furnace 1, that is, the part located outside the partition plate 7, and its height gradually decreases. In this way, the eddy current impact on the flue gas in this area will be reduced. The closer to the central area of the partition plate 7, the flue gas has been separated, and the flue gas near the delay hood 113 needs to reduce the eddy current effect to facilitate the escape of the flue gas from the conveying cylinder 111. Therefore, the eddy current effect of the flue gas near the delay hood 113 can be appropriately reduced. Therefore, the height of the area of the driving fan blade 105 near the delay hood 113 is relatively high, so the eddy current effect of the flue gas in this part of the area is more obvious, and the effect of promoting the driving fan blade 105 will be stronger. Generally speaking, the existence of the driving fan blade 105 can be propelled by the stronger eddy current near the delay hood 113, and secondly, it can also meet the purpose of reducing the eddy current effect of the flue gas in this area.

[0046] It should be noted that, first, the driving fan blade 105 only affects the eddy current effect of part of the flue gas in the area of the delay hood 113, so as to achieve the purpose of driving the driving fan blade 105 by means of the eddy current effect of the flue gas in this area. Second, there is a spiral pushing blade 112 in this area to realize the transportation of the flue gas. Therefore, there is a mutually compensating mechanism to adapt to the operation of the system. That is to say, the annular V-shaped separation area formed by the conical partition plate 7 and the inverted conical delay hood 113 forms a local backflow through the sudden change of the flow channel cross-section. When the flue gas generates a spiral upward movement under the drive of the eddy current fan 6, it generates a secondary circulation under the guidance of the V-shaped structure, and the axial flow velocity is reduced by more than 30%. The effective separation time of the particulate matter is extended to 2.1 times that of the traditional device. At the same time, the V-shaped flow channel strengthens the particle size classification effect, and the coarse particles settle preferentially in the circulation.

[0047] Specifically, when the driving fan blade 105 rotates, it drives the mounting rod 103 to rotate through the connecting rod 102, so that the scraper 104 scrapes off the oil droplets accumulated on the surface of the partition plate 7.

[0048] The oil droplets after scraping will flow to the periphery of the partition plate 7 after passing through the surface of the partition plate 7. Since the partition plate 7 has a regular conical structure, its surface is inclined. After the scraped oil droplets converge, they will converge at the joint between the partition plate 7 and the inner wall of the centrifugal furnace 1 under the action of gravity. Secondly, the oil droplets after centrifugal separation on the inner wall of the centrifugal furnace 1 will also fall under the action of gravity. Therefore, a plurality of liquid leakage holes 8 are circumferentially formed around the periphery where the partition plate 7 contacts the inner wall of the centrifugal furnace 1, so that the oil droplets will gradually flow into the oil droplet collection device arranged at the bottom of the collection furnace 2 through the liquid leakage holes 8 for collection.

[0049] In summary, through the centrifugal force dynamic compensation mechanism of the multi-stage separation chamber 3, the residence time optimization of the V-shaped flow field reconstruction, the pre-acceleration characteristics of the spiral pushing blade 112, the self-cleaning function of the oil scraping assembly 10, and the escape suppression design of the blocking cover 12, a five-dimensional collaborative strengthening effect is formed, thereby effectively solving the problem that in the primary separation stage of the existing centrifugal purification equipment, due to the centrifugal force gradient stratification formed after the flue gas enters and the limitation of the equipment height, the residence time is insufficient, so that the particulate matter in the flue gas cannot be fully separated, affecting the overall purification effect.
