Description

Technical Field

[0001] The present invention relates to the technical field of flue gas treatment, and more specifically, to a device for treating dust particles in coal-fired flue gas. Background Art

[0002] Smoke is solid particulate matter emitted during coal burning and industrial production. Its main components are silicon dioxide, aluminum oxide, iron oxide, calcium oxide and unburned carbon particles. There are many types of air pollutants, which can be divided into two categories according to their form, namely particulate pollutants and harmful gases. Smoke belongs to particulate pollutants.

[0003] For the treatment of flue gas, generally before the flue gas is discharged, it needs to be pre-treated by a purifier placed between the flues. The flue gas is purified through dust removal, sulfur removal, nitrogen removal and other processes to make the discharged flue gas meet environmental protection standards. Purification equipment usually adopts various technologies, such as electrostatic precipitator, bag filter, desulfurization device, etc., to remove particulate matter and other pollutants in the flue gas. In the process of equipment treating flue gas, many factors are involved, including reaction conditions and reaction amount, as well as temperature conditions, temperature change during purification process and other factors. Therefore, after the coal-fired flue gas is treated by purification equipment, the emission of particulate matter will be greatly reduced, that is, the concentration of particulate matter emitted from the coal-fired flue gas will be significantly reduced, that is, the concentration of particulate matter emitted from the coal-fired flue gas will be significantly reduced, and the particulate matter cannot be completely removed, resulting in some particulate matter still existing in the purified flue gas. For some purified particles, they will be discharged with the flue gas. Although the emission standards are met, the particulate matter in the flue gas will still have a certain impact on the surrounding environment.

[0046] Specifically, the connection cover 3 is a protective part of the particle processing device 2, which provides effective protection for the entire processing part after installation, and is connected with the corresponding processing part through the rotating groove 301 and the tooth groove 302, which also ensures the stability and linkage of the processing part during operation;

[0047] The top cover 4 includes a ring sheet 401 for fixing the particle processing device 2 as a whole, a connecting seat 402 arranged at the center of the ring sheet 401 and connected to the ring sheet 401 through a mesh body, and a fan blade a405 arranged at the bottom side of the connecting seat 402 for providing drainage for the filtered smoke;

[0048] Specifically, the top cover 4 mainly serves to guide the filtered smoke.

The mesh structure can prevent impurities in the outside air from entering the smoke pipe 1.

[0049] The cover plate 5 is connected to a fixed plate 406 with a connecting rod at the bottom of the fan blade a405 and is engaged with the rotating groove 301 to isolate and filter the front and rear smoke;

[0050] Specifically, the cover plate 5 is mainly used for dividing the smoke before filtration and the smoke after filtration, and the fan blade a405 generates a force to drive the smoke in one partition to flow through the inside of the cleaning seat 8 to another partition, thereby improving the adequacy and thoroughness of the filtration;

[0051] The particle processing assembly 6 comprises a connecting column 9 connected to the center of the bottom end surface of the cover plate 5 and at least two groups of cleaning seats 8 arranged on the connecting column 9 and arranged in a circumferential manner, a guide seat a801 radially inclined with the cleaning seat 8 is arranged at one end of the cleaning seat 8, and a guide seat b802 radially bent with the cleaning seat 8 and penetrating the cover plate 5 is arranged at the other end, the cleaning seat 8 is hollow inside and is provided with a separation blade 10 for filtering smoke, a transmission cavity 804 is arranged in the outer wall of the cleaning seat 8, a transmission assembly 13 for transmitting the separation blade 10 is arranged in the transmission cavity 804, and a driving part of the transmission assembly 13 penetrates the transmission cavity 804 and is meshed with the tooth groove 302;

[0052] Specifically, the particle processing assembly 6 rotates synchronously with the help of the transmission of the fan blade a405. Under the effect of the lateral rotation, multiple cleaning seats 8 can be moved to different areas within the filter partition, thereby improving the range of smoke adsorption and the comprehensiveness of smoke circulation in the cleaning seat 8. At the same time, the smoke entering the cleaning seat 8 will be cleaned by the internal synchronously rotating separation blades 10 to clean the particles in the smoke.

[0053] The exhaust assembly 7 includes a collecting hood 11 connected to the inside of the cleaning seat 8 and a flow pipe 12 connected to the bottom of 9, 11 is connected to a guide pipe 1101 which is in an inclined structure and is connected to the flow pipe 12, the flow pipe 12 is provided with a rotating seat b1201 in an integrated structure, the rotating seat b1201 is provided with a fan blade b1202 for guiding the smoke, the connection of the rotating seat b1201 is rotatably connected to a discharge pipe connection end 1203, and the discharge pipe connection end 1203 is provided with a discharge pipe connected to the outside of the smoke pipe 1;

[0054] Specifically, the exhaust assembly 7 mainly guides the smoke in the smoke pipe 1 on the one hand, and uniformly collects and discharges the processed smoke particles on the other hand;

[0055] In summary, the dust particle treatment device 2 for coal-fired flue gas can be installed on the equipment of the particle treatment link in the flue gas treatment process, and can also be installed on the top of the external exhaust chimney. At the same time, according to the overall size, it is also suitable for smoke pipes 1 of different sizes. The installation based on the external exhaust type includes the following steps:

[0056] ① Measure the overall height of the particle processing device 2 and calculate the specific position of the exhaust pipe on the smoke pipe 1, and open an inclined pipe hole on the smoke pipe 1 according to the specific position;

[0057] ② Determine the position of the device and the tube hole, and insert the device into the smoke pipe 1 from the exhaust port of the smoke pipe 1. After insertion, the ring piece 401 will be limited on the exhaust port, and the device is fixed on the exhaust port by screws;

[0058] ③Insert the drain pipe into the smoke pipe 1 through the pipe hole and dock it with the device, and fix the drain pipe to the outer wall of the smoke pipe 1 with screws;

[0059] It should be noted that in actual applications, the drain pipe connection end 1203 in the case needs to be designed to be curved, and the interface of the curved end is a threaded structure. After the drain pipe is embedded and the position is corresponding, the drain pipe and the drain pipe connection end 1203 are threadedly connected and locked by rotation. At the same time, a fixing plate of corresponding size is embedded on the drain pipe, and the fixing plate is locked with the outer wall of the smoke pipe 1 by screws to limit the drain pipe as a whole. A slidable and adjustable fixing plate can also be set on the outer wall of the drain pipe. Either of the two can be selected;

[0060] ④ Plan the circuit of the motor 403, connect the motor 403 to the power supply, and perform execution control through the controller;

[0061] The process of cleaning dust particles in flue gas by this device includes the following:

[0062] The smoke moves from the bottom to the top of the smoke pipe 1, and the motor 403 is started. The motor 403 will simultaneously drive the fan blade a405, the cover plate 5, the particle processing component 6 and the exhaust component 7 to rotate synchronously. At this time, the rotation of the fan blade b1202 will drive the smoke to flow upward faster. At the same time, the suction force generated by the rotation of the fan blade a405 will provide guidance for the smoke between the cover plate 5 and the fan blade b1202. During this process, it will pass through the guide seat b802 of multiple cleaning seats 8, and then pass through the inside of the cleaning seat 8 until it reaches the guide seat a801. At this time, the connecting column 9 drives the multiple cleaning seats 8 to rotate horizontally, so that the cleaning seat 8 can be in different areas between the cover plate 5 and the fan blade b1202. With the help of the suction force generated by the fan blade a405, the cover plate 5 and the fan blade b1202 can be The flue gas in different areas is guided by the cleaning seat 8. After the flue gas enters the cleaning seat 8, the transmission component 13 is meshed with the tooth groove 302 on the inner wall of the connecting cover 3 during the rotation of the cleaning seat 8. When the cleaning seat 8 rotates, the separation blade 10 in the cleaning seat 8 will also rotate accordingly. The particles in the flue gas will be intercepted by the separation blade 10. Some particles will be discharged through the particle guide port at the bottom of the cleaning seat 8 through the discharge pipe, and the other part will be on the separation blade 10. Due to the particularity of the structure of the separation blade 10, the particles in the flue gas will also pass through the gap formed between the separation blade 10 and the cleaning seat 8. Such particles will be intercepted by the partition net on the guide seat b802, and the filtered flue gas will be discharged to the outside through the part of the mesh body on the top cover 4;

[0063] It should be noted that the motor 403 needs to rotate appropriately, and the smoke should be in an obvious flowing state, and should not be too fast or too slow;

[0064] In order to realize the operation of the particle treatment device 2 and to guide the filtered flue gas, as Figure 3 , Figure 4 and Figure 6 As shown, a motor 403 for driving the particle processing device 2 as a whole is arranged on the top of the connecting seat 402, and a rotating seat a404 connected to the transmission end of the motor 403 is arranged at the bottom of the connecting seat 402, and the fan blade a405 is nested on the rotating seat a404 through the central ring sleeve and is fixed by screws, and a gap is arranged between the fan blade a405 and the ring sheet 401;

[0065] Further, in order to simplify the transmission structure of the particle processing device 2 as a whole, the particle processing device 2 as a whole adopts an integrated transmission structure, and multiple substantial parts of the particle processing device 2 are longitudinally linearly connected, and the multiple substantial parts are synchronously driven by the motor 403 on the fixed end top cover 4;

[0066] In order to achieve the above-mentioned guidance between the two areas before and after filtering, it is necessary to penetrate the guide seat b802 on the cleaning seat 8 on the cover plate 5. In order to adapt to the matching of the penetration structure, such as Figure 3 , Figure 4 As shown, the guide cover plate 5 is provided with at least two groups of through holes 501 distributed in a circumference and matching the size and position of the guide seat b802;

[0067] Furthermore, in order to achieve the compatibility of the particle processing assembly 6 installed in the connection cover 3 and the adaptability of the cleaning method, as Figure 8 and Fig.10 As shown, the cleaning seat 8 is a fan-shaped structure as a whole, the inner bottom surface of the cleaning seat 8 is inclined along the curvature of the guide seat b802, and a particle guide port connected to the collection cover 11 is provided on the bottom surface, and the separation blade 10 is rotatably connected to the particle guide port;

[0068] Based on the structure of the particle processing component 6, on the one hand, one end of the cleaning seat 8 needs to adapt to the contact end surface connected to the connecting cover 3, and also needs to adapt to the contact end surface connected to the connecting column 9. On the other hand, in order to achieve thorough cleaning, it is also necessary to consider the installation of multiple groups of cleaning seats 8 and the guide seats a801 and b802 set on the cleaning seat 8. To meet the above factors, the fan-shaped seat structure is better than other multi-deformation structures. At the same time, the number of cleaning seats 8 to be installed needs to be adapted to the size of the smoke pipe 1 in different application scenarios. At least two groups should be installed. Based on the size of the fan-shaped area of ​​the cleaning seat 8, more than two groups can be installed. The number of cleaning seats 8 affects the cleaning efficiency of the smoke.

[0069] At the same time, the outer end faces of the guide seat a801 and the guide seat b802 are inclined from the outer arc-shaped end face of the cleaning seat 8 to the inner arc-shaped end face. The guide seat a801 is a triangular hollow structure as a whole. The bottom surface of the guide seat a801 is inclined downward at a fixed angle along the bottom surface of the cleaning seat 8. In order to adapt to the probability of the connection cover 3 and the cleaning seat 8 being scratched or rubbed against the inner wall of the connection cover 3 when the connection cover 3 and the cleaning seat 8 rotate horizontally, in order to achieve the best guiding effect of the guide seat a801 while not generating a large resistance with the smoke, the bottom surface of the guide seat a801 is offset downward at a fixed angle;

[0070] In order to achieve the best separation effect when the particles in the flue gas pass through the cleaning seat 8, Figure 8 , Fig.10 and Fig.12 As shown, the separation blade 10 is divided into two filtering areas, including filtering area a1001 and filtering area b1002, and a shaft connected to the transmission assembly 13 is arranged between the filtering area a1001 and the filtering area b1002, and a partition net formed by a plurality of support rods arranged transversely is arranged on the filtering area a1001 and the filtering area b1002, and the density of the partition net on the filtering area a1001 is greater than that on the filtering area b1002;

[0071] It should also be noted that the particle guide port is larger than the separation blade 10, and a partition net formed by a plurality of horizontally arranged support rods is provided on the exhaust port of the guide seat b802, and the net body density is greater than the partition net of the filtration area a1001;

[0072] In order to avoid the problem of rapid clogging of the mesh holes when the independent mesh is used for interception and the problem of intercepting different particles, the Fig.12 , further elaborated, for the filtration of particulate matter in the flue gas, the particulate matter in the flue gas is mainly intercepted by the separation blades 10 which rotate radially in cooperation with the cleaning seat 8. In the process, the comprehensiveness of the particle feeding and the thoroughness of the filtration are taken into consideration. The specific description includes the following, such as Fig.12As shown, L1 is the longitudinal height of the cleaning seat 8, and L2 is the straight length of the outer end of a single set of separation blades 10, that is, when the separation blades 10 rotate to form a right angle with the particle guide port, there is an oblique angle gap between the separation blades 10 and the top of the cleaning seat 8. In order to achieve the best filtering effect, the density of the partition net set on the discharge port of the guide seat b802 is greater than the partition nets of the filter area a1001 and the filter area b1002. After the treatment is completed, the motor 403 rotates in the opposite direction, and the fan blades b1202 guide the air to move into the smoke pipe 1. When the air passes through the guide seat b802, the force generated during the circulation process cleans the particles attached to the separation blades 10 and the guide seat b802, and combined with the inclined bottom surface of the cleaning seat 8, the attached particles can be guided into the particle guide port. Based on the above, the three different density partition nets can also effectively realize the filtering and classification of particles of different sizes. Compared with the single density partition net, it can avoid the blockage of the net body in a short period of time.

[0073] In order to realize the discharge of the particles collected in the multiple cleaning seats 8, Figure 1-4 and Fig.11 As shown, the row pipe connection end 1203 is a conical structure, and the row pipe connection end 1203 is rotatably connected to the rotating seat b1201 through a limited rotation ring buckle. One end of the row pipe is connected to the row pipe connection end 1203, and the other end of the row pipe is downwardly inclined and penetrates the side wall of the smoke pipe 1 to be connected to the outside of the smoke pipe 1. The row pipe and the smoke pipe 1 are fixed at the penetration point.

[0074] Specifically, the conical structure of the exhaust pipe connection end 1203 can diffusely guide the rising smoke, effectively reducing the resistance of the smoke to the exhaust assembly 7 during the rising process. When performing unified exhaust, the exhaust pipe needs to be inclined to the outside of the smoke pipe 1 to greatly reduce the accumulation of particulate matter. At the same time, the exhaust pipe needs to be fixed on the smoke pipe 1 to ensure that the force generated during the lateral rotation of the particle processing device 2 during operation will not affect the exhaust pipe, thereby enhancing the firmness and stability of the exhaust pipe itself.

[0075] In order to realize the driving of the separation blade 10, as Figure 7-9 and Fig.13 As shown, it is realized by a transmission assembly 13 of a radial transmission structure, the transmission assembly 13 includes a gear a1301, a tooth seat 1302 and a gear b1303, the gear a1301 and the gear b1303 are radially meshed and connected, one end of the tooth seat 1302 is fixed to the center of the inner end surface of the gear a1301, and the other end is connected to the shaft of the separation blade 10, and a gear c1304 of an integrated structure is arranged on the bottom surface of the gear b1303, and the gear c1304 is meshed with the tooth groove 302 on the inner wall of the connection cover 3 through the transmission port 803 arranged on the transmission cavity 804;

[0076] It is further explained that the transmission assembly 13 mainly realizes the change of transmission direction through the radial meshing of two sets of bevel gears. The whole is meshed with the tooth groove 302 on the inner wall of the connecting cover 3 through the plate-shaped gear connected to the transverse bevel gear. When the particle processing device 2 is running, with the help of the lateral rotation of the cleaning seat 8, the meshing transmission between the plate-shaped gear and the tooth groove 302 is used as the driving source, and the separation blade 10 is transmitted through the longitudinal bevel gear.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
