Description

Technical Field

[0001] The present invention relates to the technical field of industrial flue gas treatment, and particularly to a ceramic filter tube integrated intelligent flue gas purification device. Background Art

[0002] The principle of ceramic filter tubes for purifying industrial flue gas is mainly based on their unique physical structure and material properties. Through the synergistic effect of physical filtration and surface capture mechanisms, efficient separation of particulate matter in the flue gas is achieved. Specifically, ceramic filter tubes have a complex three-dimensional porous structure. Their micron-sized pore diameters can mechanically intercept larger-sized particulate matter. At the same time, the huge specific surface area provided by the internal porous channels promotes the collision, adsorption, and deposition of particulate matter when passing through, forming a deep filtration effect.

[0003] When ceramic filter tubes are used to purify industrial flue gas, a catalyst is loaded on the surface of the filter tubes. After ammonia is injected into the flue gas and evenly mixed, when the flue gas passes through the ceramic filter tubes containing the catalyst, the catalyst provides reactive sites for the reaction between ammonia and nitrogen oxides (NOx) in the flue gas. Under the action of the catalyst, ammonia and nitrogen oxides undergo a selective catalytic reduction (SCR) reaction to convert nitrogen oxides into harmless nitrogen and water. Combining with the filtration function of the ceramic filter tubes themselves, dust particles in the flue gas can be removed synchronously, realizing the integrated treatment of dust removal and denitrification, and effectively reducing pollutant emissions.

[0004] During the flue gas treatment process, the purification efficiency of the flue gas is not good. The main reasons are as follows. The traditional pre-mixer results in a short mixing path and poor mixing uniformity between ammonia and the flue gas. Secondly, dust in industrial flue gas will continuously deposit on the surface of the ceramic filter tubes, hindering the contact between ammonia and nitrogen oxides in the flue gas with the catalyst surface, weakening the intensity of the selective catalytic reduction (SCR) reaction. Although a pulse back-blowing system is often equipped in flue gas treatment, due to the fixed wind direction, dust is likely to reattach to the catalyst surface during the dust cleaning process. This is because the airflow with a fixed wind direction cannot fully cover and effectively remove dust in all areas when purging the filter tubes, and some dust reattaches to the catalyst surface under the disturbance of the airflow. Therefore, in order to solve the above problems, a ceramic filter tube integrated intelligent flue gas purification device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantage of poor purification efficiency of flue gas in the prior art, and to propose a ceramic filter tube integrated intelligent flue gas purification device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

A plurality of ceramic filter tubes are installed inside the purification tower body. An absorption tube is installed on the purification tower body. A backwashing assembly is installed inside the purification tower body. The backwashing assembly includes a plurality of pulse backwashing control bodies slidably arranged outside the purification tower body. A nozzle is rotatably arranged at the air outlet of the pulse backwashing control body. A plurality of nozzles are arranged in a circumferential array at equal intervals and in a threaded manner on the nozzle. The plurality of nozzles can rotate and reciprocate at the same time. The nozzles are used for cleaning the ash on the ceramic filter tubes. The absorption tube is used for adsorbing the dust suspended in the purification tower body;

[0008] A mixing assembly is arranged inside the mixing tank. The mixing assembly includes a rotatably arranged mixing fan blade. A second mixing tube, a third mixing tube and a first mixing tube are installed inside the mixing tank. The second mixing tube, the third mixing tube and the first mixing tube are all provided with mixing guide vane groups. The mixing fan blade and the mixing guide vane groups are used for mixing ammonia gas and flue gas. The second mixing tube, the third mixing tube and the first mixing tube are used for extending the mixing path.

[0009] The above technical solution further includes:

[0010] The backwashing assembly further includes a fixed sliding plate. The fixed sliding plate is fixedly connected to the outside of the purification tower body. The air outlet end of the pulse backwashing control body is fixedly connected with a connecting head. One end of the connecting head away from the pulse backwashing control body is rotatably connected with an air duct rotatably connected to the purification tower body. The nozzle is installed on the outside of the air duct. The nozzle is installed on the outside of the nozzle.

[0011] A plurality of the air ducts extend to the outside of the purification tower body and one end away from the pulse backwashing control body is fixedly connected with a driving head. A reciprocating groove is formed in the driving head. A sleeve is fixedly connected to one side of the purification tower body close to the driving head. A driven gear is rotatably connected to the sleeve. A convex block is arranged inside the driven gear and is engaged and slid with the reciprocating groove.

[0012] A driving motor is fixedly connected to the top of the purification tower body. A driving gear is installed at the output end of the driving motor. A plurality of the driven gears are meshed with each other adjacent to each other. One of the driven gears is meshed with the driving gear.

[0013] An installation plate is fixedly connected to the inside of the purification tower body. A plurality of the ceramic filter tubes are installed on the installation plate. A plurality of wind baffle plates are installed inside the purification tower body. A dust discharge valve is installed at the bottom of the purification tower body. A smoke outlet is installed at the top of the purification tower body.

[0014] The mixing assembly further includes a mixing motor, which is installed on the mixing tank. The output end of the mixing motor is fixedly connected to a transmission shaft, and the transmission shaft is fixedly connected to the mixing fan blades.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, in the backwashing assembly, a plurality of nozzles arranged on the spray pipe can rotate and reciprocate at the same time. This design enables the nozzles to interact with each other, generating a strong spiral air flow. The air flow covers the surface of the ceramic filter pipe more comprehensively and evenly, effectively removing the dust on the filter pipe. At the same time, the heavy dust directly falls to the bottom of the purification tower body, and the floating dust particles reach the bottom of the purification tower body through the absorption pipe, reducing the adhesion on the filter pipe.

[0021] 2. In the present invention, the rotation of the mixing fan blades can initially stir and mix ammonia and flue gas. The plurality of mixing pipes and the mixing guide vane group inside them further extend the mixing path, increasing the contact time and mixing degree of ammonia and flue gas, enabling the two to be more fully mixed evenly. When the fully mixed ammonia and flue gas enter the subsequent purification process, they can more efficiently carry out selective catalytic reduction (SCR) reaction, converting nitrogen oxides into harmless nitrogen and water, significantly improving the denitration efficiency.

[0031] 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.

[0032] Embodiment

[0033] Such as Figures 1-7As shown in the figure, an integrated intelligent flue gas purification device with ceramic filter tubes proposed by the present invention includes a mixing tank 1 and a purification tower body 2. A plurality of ceramic filter tubes 41 are installed inside the purification tower body 2. An absorption pipe 6 is installed on the purification tower body 2. An air blowing-back component is installed inside the purification tower body 2. The air blowing-back component includes a plurality of pulse air blowing-back control bodies 3 slidably arranged outside the purification tower body 2. A spray pipe 34 is rotatably arranged at the air outlet of the pulse air blowing-back control body 3. A plurality of nozzles 35 are arranged in an equidistant threaded circular arrangement on the spray pipe 34. The plurality of nozzles 35 can rotate and reciprocate at the same time. The nozzles 35 are used for cleaning the ash of the ceramic filter tubes 41. The absorption pipe 6 is used for adsorbing the dust suspended in the purification tower body 2;

[0034] A mixing component is arranged inside the mixing tank 1. The mixing component includes a rotatably arranged mixing fan blade 11. A second mixing pipe 15, a third mixing pipe 17 and a first mixing pipe 16 are installed inside the mixing tank 1. Mixing guide vane groups 111 are installed on the second mixing pipe 15, the third mixing pipe 17 and the first mixing pipe 16. The mixing fan blade 11 and the mixing guide vane groups 111 are used for mixing ammonia and flue gas. The second mixing pipe 15, the third mixing pipe 17 and the first mixing pipe 16 are used for extending the mixing path;

[0035] Furthermore, in the actual production and operation process, multiple purification tower bodies 2 are often connected in series and parallel.

[0036] Furthermore, when the dusty flue gas and ammonia enter the mixing tank 1, the mixed gas flow of the flue gas and ammonia enters the first mixing pipe 16. The mixing guide vane group 111 inside the first mixing pipe 16 plays a guiding and disturbing role on the gas flow. When the gas flow passes through the mixing guide vane group 111, the flow direction and speed change, further promoting the mixing of ammonia and flue gas. At the same time, the first mixing pipe 16 extends the mixing path, allowing the two to have a longer contact time for mixing.

[0037] Furthermore, then the gas flow enters the third mixing pipe 17, and the mixing guide vane group 111 inside it guides and disturbs the gas flow again, further strengthening the mixing effect and continuing to extend the mixing path to ensure the full mixing of ammonia and flue gas. Then the gas flow enters the second mixing pipe 15. Similarly, through the action of the mixing guide vane group 111 and the extension of the path, ammonia and flue gas reach a highly uniform mixing state. Subsequently, the mixing fan blade 11 starts to rotate under the drive of the gas flow or the action of external power, further stirring and mixing the mixed gas of ammonia and flue gas, so that the two complete the final mixing, creating good conditions for the subsequent selective catalytic reduction (SCR) reaction occurring in the purification tower body 2.

[0038] Further, the fully mixed flue gas and ammonia enter the purification tower body 2. At this time, the ceramic filter tube 41 starts to play a filtering role. Particulates in the flue gas are intercepted on the surface of the ceramic filter tube 41, while the clean gas is discharged through the ceramic filter tube 41. After the ceramic filter tube 41 works for a period of time, dust will gradually accumulate on the surface, resulting in an increase in the filtration resistance. At this time, it is necessary to clean the ash. A plurality of pulse back-blow control bodies 3 slidably arranged on the outer side of the purification tower body 2 start to work. A nozzle 34 is rotatably arranged at the air outlet of the pulse back-blow control body 3. A plurality of nozzles 35 are arranged in a circumferential array at equal intervals on the nozzle 34 in a threaded manner. The plurality of nozzles 35 can rotate and reciprocate at the same time. The pulse back-blow control body 3 controls the nozzles 35 to eject high-speed air flow according to a preset program or the ash accumulation condition of the ceramic filter tube 41 monitored in real time. The rotation and reciprocation of the nozzles 35 enable the cleaning air flow to comprehensively and evenly cover the surface of the ceramic filter tube 41, blow off the dust on the surface of the ceramic filter tube 41, and restore the filtration performance of the ceramic filter tube 41.

[0039] Further, in the mixing tank 1, in addition to the mixing of ammonia and flue gas and the filtration process of the ceramic filter tube 41, some suspended dust will also be generated. The absorption tube 6 installed on the purification tower body 2 plays a role. A part of the air flow ejected by the nozzles 35 passes through the absorption tube 6. The gas enters the ash hopper at the bottom of the purification tower body 2 from the purification tower body 2. There are multiple connections between the absorption tube 6 and the purification tower body 2. Through negative pressure adsorption, the suspended dust in the mixing tank 1 is adsorbed and collected, avoiding the accumulation and diffusion of dust in the device, and ensuring the stable and efficient operation of the entire flue gas purification device.

[0040] The back-blow assembly further includes a fixed slide plate 30. The fixed slide plate 30 is fixedly connected to the outer side of the purification tower body 2. The air outlet end of the pulse back-blow control body 3 is fixedly connected with a connector 31. One end of the connector 31 away from the pulse back-blow control body 3 is rotatably connected with an air duct 33 rotatably connected to the purification tower body 2. The nozzle 34 is installed on the outer side of the air duct 33, and the nozzle 35 is installed on the outer side of the nozzle 34;

[0041] A plurality of air ducts 33 extend to the outer side of the purification tower body 2 and one end away from the pulse back-blow control body 3 is fixedly connected with a driving head 36. A reciprocating groove 32 is formed in the driving head 36. A sleeve 52 is fixedly connected to one side of the purification tower body 2 close to the driving head 36. A driven gear 51 is rotatably connected to the sleeve 52. A convex block is arranged inside the driven gear 51 and is engaged and slid with the reciprocating groove 32;

[0042] A driving motor 5 is fixedly connected to the top of the purification tower body 2. The output end of the driving motor 5 is provided with a driving gear 50. A plurality of driven gears 51 are meshed with each other adjacent to each other in pairs, and one of the driven gears 51 is meshed with the driving gear 50;

[0043] Further, the fixed slide plate 30 is fixedly connected to the outside of the purification tower body 2 to play a role in support and positioning. The air outlet end of the pulse backwashing control main body 3 is fixedly connected with a connector 31. One end of the connector 31 away from the pulse backwashing control main body 3 is rotatably connected with an air duct 33, and the air duct 33 is rotatably connected with the purification tower body 2. The spray pipe 34 is installed on the outside of the air duct 33. In this way, the high-speed air flow generated by the pulse backwashing control main body 3 enters the air duct 33 through the connector 31 and is then transmitted to the spray pipe 34;

[0044] Further, the spray nozzles 35 are installed on the outside of the spray pipe 34. These spray nozzles 35 are the key components for implementing ash cleaning. They spray the high-speed air flow onto the surface of the ceramic filter tube 41 to remove the dust on the filter tube;

[0045] Further, during the flue gas purification, it is necessary to regularly clean the dust attached to the ceramic filter tube 41. The mixed gas of ammonia and flue gas continues to mix and enter the interior of the purification tower body 2. At this time, the drive motor 5 is started, the driving gear 50 rotates, driving the driven gear 51 meshing with it to rotate. Since multiple driven gears 51 are meshed with each other, all the driven gears 51 will rotate synchronously. Through the engagement and sliding of the convex blocks inside the driven gear 51 with the reciprocating groove 32 on the driving head 36, the rotation is converted into the reciprocating motion of the spray nozzles 35. At the same time, the convex blocks inside the driven gear 51 squeeze the reciprocating groove 32, so that while the spray pipe 34 drives the air duct spray nozzles 35 to reciprocate, it also performs spiral rotation;

[0046] Further, since the spray nozzles 35 can rotate and reciprocate simultaneously, the sprayed high-speed air flow can comprehensively and evenly cover the surface of the ceramic filter tube 41. The rotation enables the air flow to blow towards the filter tube from different angles, and the reciprocating motion ensures that all parts of the filter tube surface can be impacted by the air flow, thereby completely blowing off the dust on the surface of the ceramic filter tube 41, restoring the filtering performance of the ceramic filter tube 41, and ensuring the continuous and efficient operation of the flue gas purification device.

[0047] An installation plate 4 is fixedly connected to the inside of the purification tower body 2. Multiple ceramic filter tubes 41 are installed on the installation plate 4. Multiple wind baffle plates 7 are installed inside the purification tower body 2. A dust discharge valve 8 is installed at the bottom of the purification tower body 2. An exhaust port 20 is installed at the top of the purification tower body 2;

[0048] Further, during the dust removal period, a part of the flowing gas generated by the spray nozzles 35 enters the interior of the purification tower body 2 through the absorption tube 6, and a part enters the interior of the purification tower body 2 through the ceramic filter tube 41. At the same time, after the mixed gas of ammonia and flue gas enters the interior of the purification tower body 2, it is filtered by the ceramic filter tube 41 and discharged through the exhaust port 20.

[0049] The mixing assembly further includes a mixing motor 10, which is installed on the mixing tank 1. The output end of the mixing motor 10 is fixedly connected to a transmission shaft 112, and the transmission shaft 112 is fixedly connected to the mixing fan blade 11. There is a fixed connection of a smoke inlet pipe 110 between the mixing tank 1 and the purification tower body 2;

[0050] Inside the mixing tank 1, a first partition 12, a second partition 13 and a third partition 14 are respectively fixedly connected, and the first partition 12, the second partition 13 and the third partition 14 are arranged in sequence;

[0051] The second mixing pipe 15 is installed inside the first partition 12, the second partition 13 and the third partition 14. The first mixing pipe 16 is installed inside the second partition 13, the third partition 14 and the mixing tank 1. The third mixing pipe 17 is installed inside the second partition 13 and the third partition 14;

[0052] One end of the first mixing pipe 16 extending to the outside of the mixing tank 1 is fixedly connected to an ammonia interface 18 and a flue gas interface 1. The mixing guide vane group 111 is arranged by helically interleaving multiple sector-shaped blades;

[0053] Further, ammonia and flue gas enter the first mixing pipe 16 from the ammonia interface 18 and the flue gas interface 19. The first mixing pipe 16 is installed inside the second partition 13, the third partition 14 and the mixing tank 1. The mixing guide vane group 111 inside the first mixing pipe 16 is arranged by helically interleaving multiple sector-shaped blades. When the air flow passes through, the helically interleaving sector-shaped blades will play a guiding and disturbing role on the air flow. Under the action of the blades, the flow direction of the air flow changes continuously, forming complex vortices and turbulences, greatly increasing the contact area and mixing time between ammonia and flue gas, and enabling the two to perform preliminary deep mixing in the first mixing pipe 16.

[0054] Further, it enters the third mixing pipe 17, and the third mixing pipe 17 is installed inside the second partition 13 and the third partition 14. The mixing guide vane group 111 inside the third mixing pipe 17 also plays a guiding and disturbing role to perform secondary mixing enhancement on the gas. Further, subsequently, the gas enters the second mixing pipe 15, and the second mixing pipe 15 is installed inside the first partition 12, the second partition 13 and the third partition 14. Similarly, the mixing guide vane group 111 inside the second mixing pipe 15 will perform re-guiding and disturbing on the air flow, enabling the gas to be further fully mixed inside the second mixing pipe 15. The second mixing pipe 15 extends the mixing path of the gas, allowing ammonia and flue gas to have a longer time for molecular-level mixing and improving the mixing uniformity.. Through the design of multi-stage mixing pipes, the gas experiences multiple mixings and path extensions inside the mixing tank 1, and ammonia and flue gas can reach a state of highly uniform mixing.

[0055] Further, the hybrid motor 10 is installed on the mixing tank 1 as the power source of the mixing assembly. After the hybrid motor 10 is started, its output end drives the transmission shaft 112 to rotate. Since the transmission shaft 112 is fixedly connected to the mixing fan blade 11, the mixing fan blade 11 is driven to rotate at a high speed. After the ammonia gas and the flue gas are mixed in the above three stages, the rotation of the mixing fan blade 11 will finally stir and mix the just-entered ammonia gas and flue gas. The rotation of the fan blade causes strong disturbance of the air flow, prompting the ammonia gas and flue gas molecules to collide and mix with each other, realizing the final physical mixing.

[0056] Further, the fully mixed ammonia gas and flue gas enter the purification tower body 2 through the smoke inlet pipe 110 fixedly connected between the mixing tank 1 and the purification tower body 2. At this time, the uniformly mixed ammonia gas and flue gas create good conditions for the subsequent selective catalytic reduction (SCR) reaction in the purification tower body 2, which helps to improve the denitration efficiency and reduce the emission concentration of nitrogen oxides in the flue gas.

[0057] In this embodiment, the dusty flue gas and ammonia gas enter the mixing tank 1 and first enter the first mixing pipe 16. The internal mixing guide vane group 111 in it guides and disturbs the air flow, extending the mixing path. Then the air flow sequentially enters the third mixing pipe 17 and the second mixing pipe 15. After being acted on by the internal mixing guide vane group 111 and the path is extended, then the mixing fan blade 11 rotates and stirs, so that the ammonia gas and the flue gas complete the final mixing, reaching a highly uniform mixing, creating conditions for the subsequent SCR reaction.

[0058] The fully mixed gas enters the purification tower body 2. The ceramic filter tube 41 filters the flue gas, and the particulate matter is intercepted, and the clean gas is discharged. After the ceramic filter tube 41 is ash-laden, the pulse back-blow control main body 3 works, the spray head 35 rotates and reciprocates, and high-speed air flow is sprayed to clean the ash comprehensively and evenly. In addition, suspended dust will be generated in the mixing tank 1 during the operation of the device. The absorption pipe 6 on the purification tower body 2 plays a role, and uses negative pressure adsorption to adsorb and collect the suspended dust in the mixing tank 1, avoiding the accumulation and diffusion of dust in the device. Through the above series of processes, the device realizes the efficient purification of the flue gas, the timely cleaning of the ceramic filter tube 41, and the effective collection of the dust in the device, ensuring the stable and efficient operation of the entire flue gas purification device.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
