Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, and in particular to a coal-fired chamber back-blowing bag-type dust removal device. Background Art

[0002] The exhaust gas from thermal power plants contains a lot of dust. At present, electrostatic precipitators are used to filter these dusts, but the filtration effect of electrostatic precipitators on dusts is poor. Bag filters can filter dusts up to 99%, but there are still some shortcomings in the operation of back-blowing bag filter equipment.

[0003] With reference to the patent CN116492780B, a bag-type pulse back-blowing dust removal device is disclosed, comprising a shell, the bottom end of the shell is fixedly connected to a dust collecting hopper, the bottom end of the dust collecting hopper is fixedly connected to a dust exhaust assembly, one side of the top of the shell is fixedly connected to a main connecting pipe, one end of the main connecting pipe is fixedly connected to an air pipe, the air pipe is arranged in the shell, the bottom end of the air pipe is fixedly installed with a plurality of shift assemblies through a threaded structure, the bottom end of the shift assembly is fixedly connected to a nozzle, the bottom of the nozzle is provided with a support plate, the support plate is provided with a plurality of bag mounting holes, and the top edge of the bag mounting hole is provided with a plurality of limit assemblies. The dust exhaust assembly can quantitatively discharge the backblown dust, which is convenient for collecting the dust removed; the shift assembly drives the nozzle to move, and then can drive the nozzle to extend into the installed dust bag, and when the nozzle performs pulse backblowing, the dust bag can be blown comprehensively, thereby improving the effect of backblowing dust removal.

[0004] Based on the search of the above patents and combined with the current operation of bag dust removal, it is found that the current bag dust removal equipment still has the following two shortcomings:

[0005] First, when the bag is blown in reverse to remove dust, since the direction of the airflow from the nozzle is fixed, the bag is in a relatively static state at this time, and some dust will adhere to the outside of the bag and cannot fall off, which will have an adverse effect on the subsequent dust filtration;

[0006] Secondly, when the dust falls into the collection bin, it is difficult to completely remove the dust at the bottom of the collection bin, so that when the gas enters the purification room again, the dust at the bottom of the collection bin will be suspended in the air again, which is not conducive to filtering the dust in the gas. Summary of the invention

[0007] In view of this, the present invention provides a coal-fired chamber back-blowing bag dust collector. When the fan blades at the outer end of the rotating shaft rotate, the impact force of the airflow blowing onto the surface of the ring and the fixed box is different, so the ring and the fixed box will swing, and an empty groove is opened inside the fixed box, and a ball is arranged inside the empty groove. Therefore, when the fixed box and the ring swing, the ball will also roll inside the empty groove, which intensifies the swing amplitude of the ring. When the ring swings, the surface of the dust bag will also vibrate, so that the dust on the outer end of the dust bag can fall off faster, and a compression spring is also installed at the lower end of the ring. Under the action of the elastic force of the compression spring, the vibration amplitude of the ring can be increased. Blades are fixedly installed on the outside of the driving shaft, and the blades have a spiral structure. The outer end surface of the blade fits with the inner end surface of the collecting bin, so that when the driving motor drives the driving shaft and the blades to rotate, the spiral blades can push the dust inside the collecting bin forward and discharge it from the discharge pipe.

[0024] The present invention provides a coal-fired chamber back-blowing bag-type dust removal device, which has the following beneficial effects:

[0025] In the present invention, a dust bag is fixedly installed in the through hole at the top of the purification chamber, and the top of the dust bag is connected to the exhaust chamber, so that gas can enter the exhaust chamber through the dust bag. When the gas passes through the dust bag, dust in the gas will adhere to the outer end surface of the dust bag, so the dust in the gas can be filtered. After the gas is filtered, the first-level air pipe is externally connected to a fan, and the gas can enter the three second-level air pipes through the first-level air pipe and be sprayed out from the nozzle at the lower end of the second-level air pipe.

[0027] In addition, through the rotating connection inside the lower connecting ring, there is a rotating setting, so that when the fan blades at the outer end of the rotating shaft rotate, the impact force of the airflow blowing onto the surface of the ring and the fixed box is different, so the ring and the fixed box will swing, and an empty groove is opened inside the fixed box, and a ball is arranged inside the empty groove. Therefore, when the fixed box and the ring swing, the ball will also roll inside the empty groove, which intensifies the swing amplitude of the ring. When the ring swings, the surface of the dust bag will also vibrate, so that the dust on the outer end of the dust bag can fall off faster, and a compression spring is also installed at the lower end of the ring, and the vibration amplitude of the ring can be increased under the action of the compression spring elastic force.

[0028] In addition, the gas blown out of the nozzle blows the dust on the outer end of the dust bag into the interior of the collecting bin.

The front end of the drive motor is driven by a drive shaft, and blades are fixedly installed on the outside of the drive shaft. The blades are in a spiral structure, and the outer end faces of the blades are in contact with the inner end surface of the collecting bin, so that when the drive motor drives the drive shaft and the blades to rotate, the spiral blades can push the dust inside the collecting bin forward and discharge it from the discharge pipe.

[0044] Example 1: Please refer to Figures 1 to 9 As shown:

[0045] The present invention provides a coal-fired chamber back-blowing bag-type dust removal device, comprising a purification chamber 1;

After purification, the clean gas will enter the exhaust chamber 2 from the purification chamber 1, and then be discharged into the atmosphere from the exhaust pipe 201;

[0048] The driving motor 3 is fixedly mounted on the right side plate surface of the collecting bin 102, the front end of the driving motor 3 is drivingly connected to the driving shaft 301, and the end of the driving shaft 301 is rotatably connected to the left side plate of the collecting bin 102;

[0049] The dust bag 4, the lower end of the dust bag 4 is fixedly connected to the connecting plate 103, the top of the dust bag 4 is fixedly installed in the through hole on the surface of the top plate of the purification chamber 1, the top of the dust bag 4 is connected to the exhaust chamber 2, and an oscillation mechanism is installed inside the dust bag 4;

[0050] The first-level air pipe 8 is fixedly installed on the surface of the left side plate of the exhaust chamber 2. The front end surface of the first-level air pipe 8 is fixedly installed with a second-level air pipe 801. The second-level air pipe 801 is located inside the exhaust chamber 2. The lower end surface of the second-level air pipe 801 is evenly installed with a nozzle 8011. The nozzle 8011 is located just above the dust bag 4. The first-level air pipe 8 can be connected to the fan. After the fan is started, the gas can enter the first-level air pipe 8. Three second-level air pipes 801 are fixedly installed at the front end of the first-level air pipe 8. The gas inside the first-level air pipe 8 can enter the second-level air pipe 801 and be ejected from the nozzle 8011 at the lower end of the second-level air pipe 801. The nozzle 8011 is located just above the dust bag 4, so that the gas ejected from the nozzle 8011 can enter the dust bag 4 to clean the dust at the outer end of the dust bag 4.

[0051] The upper connecting ring 9 is fixedly mounted on the outside of the nozzle 8011 , and six fixing rods 901 are fixedly mounted on the lower end surface of the upper connecting ring 9 , and the six fixing rods 901 are arranged in a ring structure.

[0052] By adopting the above scheme, the technical effect brought about is: an air inlet pipe 101 is fixedly installed at the left end of the purification chamber 1, and the gas to be filtered enters the purification chamber 1 from the air inlet pipe 101, and a dust removal bag 4 is fixedly installed in the through hole at the top of the purification chamber 1, and the top of the dust removal bag 4 is connected to the exhaust chamber 2, and the gas can enter the exhaust chamber 2 through the dust removal bag 4. When the gas passes through the dust removal bag 4, the dust in the gas will adhere to the outer end surface of the dust removal bag 4, and the dust in the gas can be filtered. After the gas is filtered, the first-level air pipe 8 is externally connected to the fan, and the gas can enter the three second-level air pipes 801 through the first-level air pipe 8, and be ejected from the nozzle 8011 at the lower end of the second-level air pipe 801. When the gas ejected from the nozzle 8011 passes through the dust removal bag 4, the gas is blown from the inside to the outside, and the dust on the outside of the dust removal bag 4 can be blown off and fall into the collection bin 102.

[0053] Among them, the oscillation mechanism includes: a compression spring 5, which is located inside the dust bag 4, and the lowermost compression spring 5 is fixedly installed on the bottom surface of the dust bag 4; a ring 6, which is located inside the dust bag 4, and the ring 6 is located directly above the compression spring 5, and the ring 6 is fixedly connected to the compression spring 5, and a fixed box 601, which is located inside the dust bag 4 and fixedly installed on the upper surface of the ring 6, and an annular empty groove 6011 is opened inside the fixed box 601, and a ball 7 is placed inside the empty groove 6011.

[0054] By adopting the above scheme, the technical effect brought about is: when the gas is ejected from the nozzle 8011, it will impact the surface of the ring 6 and the fixed box 601. When the fan blades 1101 at the outer end of the rotating shaft 11 rotate, the impact force of the airflow blowing on the surface of the ring 6 and the fixed box 601 is different, so the ring 6 and the fixed box 601 will swing, and an empty groove 601 is opened inside the fixed box 601, and a ball 7 is arranged inside the empty groove 6011. Therefore, when the fixed box 601 and the ring 6 swing, the ball 7 will also roll inside the empty groove 6011, which intensifies the swing amplitude of the ring 6. When the ring 6 swings, the surface of the dust bag 4 will also vibrate, so that the dust on the outer end of the dust bag 4 can fall off faster, and a compression spring 5 is also installed at the lower end of the ring 6. Under the action of the elastic force of the compression spring 5, the vibration amplitude of the ring 6 can be increased.

[0055] Among them, the number of balls 7 inside the empty groove 6011 is four, and the diameter of the ball 7 is the same as the width of the empty groove 6011. During use, the outer end face of the ball 7 fits with the inner end face of the empty groove 6011, so that the ball 7 can only move in a curve along the empty groove 6011. In this process, the ball 7 is always in fit with the inner wall of the empty groove 6011, so that the ball 7 and the empty groove 6011 will not collide.

[0056] Among them, a lower connecting ring 10 is fixedly installed at the lower end of the fixing rod 901. The lower connecting ring 10 has the same structure as the upper connecting ring 9. A rotating shaft 11 is installed inside the lower connecting ring 10. Six fan blades 1101 are installed in a ring shape on the outside of the rotating shaft 11. Both ends of the rotating shaft 11 are rotatably connected to the lower connecting ring 10. The rotating shaft 11 and the fan blades 1101 are located directly below the nozzle 8011, and the rotating shaft 11 and the fan blades 1101 are located inside the dust bag 4.

[0057] By adopting the above scheme, the technical effect brought about is: the nozzle 8011 is located directly above the dust bag 4, the outer part of the nozzle 8011 is fixedly installed with an upper connecting ring 9, six fixing rods 901 are fixedly installed between the upper connecting ring 9 and the lower connecting ring 10, and the lower connecting ring 10 is rotatably connected with a rotating shaft 11, and the outer part of the rotating shaft 11 is ring-shaped with six fan blades 1101. When the nozzle 8011 sprays outward, the gas can be blown toward the fan blades 1101. At this time, the fan blades 1101 can drive the rotating shaft 11 to rotate, thereby changing the flow direction of the gas, so that the gas can be blown toward the surface of the dust bag 4 and the ring 6 in an inclined state.

[0059] By adopting the above scheme, the technical effect brought about is: the gas blown out by the nozzle 8011 blows the dust on the outer end of the dust removal bag 4 into the inside of the collecting bin 102, and the upper end part of the collecting bin 102 is in an inclined structure, so that the dust can continue to slide down to the bottom of the collecting bin 102, and the right end surface of the collecting bin 102 is fixedly installed with a drive motor 3, the front end of the drive motor 3 is driven by a drive shaft 301, and the outside of the drive shaft 301 is fixedly installed with a blade 3011, the blade 3011 is in a spiral structure, and the outer end surface of the blade 3011 is in contact with the inner end surface of the collecting bin 102, so that when the drive motor 3 drives the drive shaft 301 and the blade 3011 to rotate, the spiral blade 3011 can push the dust inside the collecting bin 102 forward and discharge it from the discharge pipe 1022.

[0060] Embodiment 2: The present invention provides a coal-fired chamber back-blowing bag dust removal device, based on the embodiment 1, such as Figure 1-Figure 9 As shown: two groups of supporting legs 1021 are fixedly installed on the lower end surface of the collecting bin 102. When the purification chamber 1 is filtering the gas, the purification chamber 1 and the collecting bin 102 will shake due to the large impact force of the gas. In actual operation, the number of supporting legs 1021 can be increased, for example, the number of supporting legs 1021 can be increased from two groups to three groups, thereby improving the supporting capacity of the purification chamber 1 and the collecting bin 102. At the same time, a mounting hole is provided in the middle position of the surface of the lower end portion of the supporting leg 1021. Workers can pass screws through the mounting holes and wedge them into the ground to fix the supporting leg 1021. Workers can also open more mounting holes on the lower end portion of the supporting leg 1021, so that more screws can be passed through the mounting holes, thereby improving the stability of the supporting leg 1021 on the ground.

[0061] Specific usage and function of this embodiment: In the present invention, an air inlet pipe 101 is fixedly installed at the left end of the purification chamber 1, and the gas to be filtered enters the purification chamber 1 from the air inlet pipe 101. A dust bag 4 is fixedly installed in the through hole at the top of the purification chamber 1. The top of the dust bag 4 is connected to the exhaust chamber 2. The gas can enter the exhaust chamber 2 through the dust bag 4. When the gas passes through the dust bag 4, the dust in the gas will adhere to the outer end surface of the dust bag 4, and the dust in the gas can be filtered. After the gas is filtered, the first-level air pipe 8 is externally connected to the fan, and the gas can enter the three second-level air pipes 801 through the first-level air pipe 8 and be ejected from the nozzle 8011 at the lower end of the second-level air pipe 801. The nozzle 8011 ejects When the gas passes through the dust bag 4, the gas blows from the inside to the outside, which can blow away the dust on the outside of the dust bag 4 and drop it into the collection bin 102. The nozzle 8011 is located directly above the dust bag 4. An upper connecting ring 9 is fixedly installed on the outside of the nozzle 8011. Six fixing rods 901 are fixedly installed between the upper connecting ring 9 and the lower connecting ring 10. A rotating shaft 11 is rotatably connected to the inside of the lower connecting ring 10. Six fan blades 1101 are installed in a ring shape on the outside of the rotating shaft 11. When the nozzle 8011 sprays outward, the gas can be blown toward the fan blades 1101. At this time, the fan blades 1101 can drive the rotating shaft 11 to rotate, thereby changing the flow direction of the gas, so that the gas can be blown toward the dust bag 4 and the ring 6 in an inclined state. When the gas is ejected from the nozzle 8011, it will impact the surface of the ring 6 and the fixed box 601. When the fan blades 1101 at the outer end of the rotating shaft 11 rotate, the impact force of the airflow blowing on the surface of the ring 6 and the fixed box 601 is different. Therefore, the ring 6 and the fixed box 601 will swing, and an empty groove 601 is opened inside the fixed box 601, and a ball 7 is arranged inside the empty groove 6011. Therefore, when the fixed box 601 and the ring 6 swing, the ball 7 will also roll inside the empty groove 6011, which intensifies the swing amplitude of the ring 6. When the ring 6 swings, the surface of the dust bag 4 will also vibrate, so that the dust on the outer end of the dust bag 4 can fall down faster, and the ring 6 A compression spring 5 is also installed at the lower end. Under the action of the elastic force of the compression spring 5, the vibration amplitude of the ring 6 can be increased. The gas blown out of the nozzle 8011 blows the dust at the outer end of the dust bag 4 into the inside of the collecting bin 102. The upper end part of the collecting bin 102 is in an inclined structure, so that the dust can continue to slide down to the bottom of the collecting bin 102, and a driving motor 3 is fixedly installed on the right end surface of the collecting bin 102. The front end of the driving motor 3 is driven by a driving shaft 301, and a blade 3011 is fixedly installed on the outside of the driving shaft 301. The blade 3011 has a spiral structure, and the outer end surface of the blade 3011 fits with the inner end surface of the collecting bin 102, so that when the driving motor 3 drives the driving shaft 301 and the blade 3011 to rotate,The spiral blade 3011 can push the dust inside the collection bin 102 forward and discharge it from the discharge pipe 1022. When installing the purification chamber 1 and the collection bin 102, two sets of support legs 1021 are fixedly installed on the lower surface of the collection bin 102. The support legs 1021 can support the purification chamber 1 and the collection bin 102. At the same time, a mounting hole is opened in the middle of the lower surface of the support leg 1021. Workers can pass the screws through the mounting hole and wedge them into the ground to fix the support legs 1021, which can improve the stability of the device and prevent the device from shaking too much.
