Description

Technical Field

[0001] The present application relates to the technical field of flue gas dust removal, and in particular, to a dust removal device. Background Art

[0002] Ceramic tube dust collector is a cyclone type dust collector. When the dust-laden gas enters the dust collector, it passes through the ceramic guide and rotates at high speed inside the cyclone. Under the action of centrifugal force, the dust and gas are separated, and the dust falls into the dust collecting box and is discharged through the ash discharge valve. The purified gas forms an ascending vortex, which is collected in the gas collecting chamber through the exhaust pipe and discharged from the chimney through the outlet to achieve the dust removal effect.

[0003] During the dust removal process, the flue gas directly blows into the ceramic tube for a long time, which easily causes the ceramic tube to break. In the existing device (for example: the authorization announcement number is: CN217367556U, the name is: a bag filter air flow guide device), the air flow guide device is set to improve the uniformity of the flue gas and reduce the impact on the ceramic tube. However, the installation of an air flow box between the induced draft fan and the dust removal bin will cause the overall structure of the dust removal device to occupy a large space.

[0026] like Figure 1 and Figure 2 As shown, embodiment 1 relates to a dust removal device, including: a dust removal structure 10 and an air distribution structure 20. The dust removal structure 10 includes a dust removal bin 11, the dust removal bin 11 has a storage space, and the dust removal bin 11 has an air inlet. The air distribution structure 20 is arranged in the dust removal bin 11, and the air distribution structure 20 and the air inlet are arranged correspondingly. The air distribution structure 20 includes a connecting plate 21, an air distribution plate 22 and a dust blocking plate 23. The air distribution plate 22 is connected to the connecting plate 21 and the dust blocking plate 23, and a plurality of first air distribution holes 221 are arranged on the air distribution plate 22.

[0027] Applying the technical solution of this embodiment, the dust removal device includes a dust removal structure 10 and an air distribution structure 20. The dust removal structure 10 includes a dust removal bin 11. The dust removal bin 11 has a storage space and an air inlet. The air distribution structure 20 can increase the uniformity of the smoke entering the dust removal bin 11. At the same time, since it is arranged in the dust removal bin 11, the overall structure of the dust removal device is compact. The air distribution structure 20 and the air inlet are arranged correspondingly, so that the smoke entering from the air inlet can first pass through the air distribution structure 20 to improve the uniformity, and then enter the dust removal bin 11. The air distribution structure 20 includes a connecting plate 21, an air distribution plate 22 and an ash blocking plate 23. The air distribution plate 22 is connected to the connecting plate 21 and the ash blocking plate 23. A plurality of first air distribution holes 221 are arranged on the air distribution plate 22. The smoke entering the dust removal bin 11 from the air inlet can greatly improve the uniformity under the action of the plurality of first air distribution holes 221. The technical solution of this embodiment effectively solves the problems in the prior art of poor uniformity of the smoke in the dust removal bin 11 and the insufficiently compact structure of the dust removal device.

[0028] It should be noted that the first end of the air equalizing plate 22 is connected to the connecting plate 21, the second end of the air equalizing plate 22 is connected to the ash blocking plate 23, and the air equalizing plate 22 is opposite to the air inlet. This allows the flue gas entering from the air inlet to pass through the air equalizing plate 22, thereby improving the uniformity of the flue gas and preventing the flue gas entering from the air inlet from directly acting on the ceramic tube 13 and causing the ceramic tube 13 to rupture.

[0029] It should also be noted that the dust removal structure 10 also includes a support portion 12, which is connected to the dust removal bin 11. The support portion 12 has multiple groups, and the multiple groups of support portions 12 are arranged along the circumference of the dust removal bin 11. The support portion 12 can improve the stability of the dust removal bin 11 and prevent the dust removal bin 11 from shaking during operation. The dust removal device also includes a support frame, which is connected to the bottom of the support portion 12 through a flange to support the dust removal device as a whole.

[0030] like Figure 2 As shown, in the technical solution of the first embodiment, a plurality of first air balancing holes 221 are arranged in an array on the air balancing plate 22, and the diameters of the plurality of first air balancing holes 221 are all the same. The flue gas entering from the air inlet passes through the plurality of first air balancing holes 221, so that the impact force acting on the ceramic tube 13 is reduced, and the uniformity of the flue gas is improved.

[0031] like Figure 2 As shown, in the technical solution of the first embodiment, the ash blocking plate 23 is arranged above the connecting plate 21, the ash blocking plate 23 has an inclination angle in the horizontal direction, and a first groove 231 is arranged on the ash blocking plate 23. The ash blocking plate 23 and the ceramic tube 13 are arranged relative to each other, and the ash blocking plate 23 is located below the ceramic tube 13. The ash blocking plate 23 can prevent the flue gas from directly acting on the ceramic tube 13. At the same time, the ash blocking plate 23 has an inclination angle, which makes it difficult for the ash material (dust, particulate matter, etc. filtered out from the flue gas) falling from the outer wall of the ceramic tube 13 to accumulate on the ash blocking plate 23. The first groove 231 fits with the support part 12 to fix the wind equalizing structure 20. It should be noted that the ash blocking plate 23 and the wind equalizing plate 22 each have two groups, the first ends of the two groups of ash blocking plates 23 are connected, and the second ends of the two groups of ash blocking plates 23 are respectively connected to the corresponding wind equalizing plates 22, and the first ends of the two groups of ash blocking plates 23 are higher than the second ends.

[0032] like Figure 2As shown, in the technical solution of the first embodiment, a second groove 211 is provided on the connecting plate 21, and the second groove 211 and the first groove 231 are provided correspondingly. The second groove 211 fits with the support portion 12, and the first groove 231 and the second groove 211 are connected to the support portion 12 together to fix the air distribution structure 20. The support portion 12 is provided on the side wall of the dust removal bin 11, and the support portion 12 is clamped in the first groove 231 and the second groove 211, so that the side wall can abut against the air distribution plate 22, the connecting plate 21 and the ash blocking plate 23, so as to achieve closure on both sides and prevent smoke from overflowing from both sides.

[0033] like Figure 2 As shown, in the technical solution of the first embodiment, the connecting plate 21 has an opening. Since the flue gas flowing out of the opening of the connecting plate 21 is directed away from the ceramic tube 13, the flue gas does not directly act on the ceramic tube 13. The flue gas flows toward the ceramic tube 13 under the rebound effect of the inner wall of the dust removal bin 11, which greatly reduces the impact force of the flue gas on the ceramic tube 13. At the same time, the opening also makes the connecting plate 21 not affect the flow rate of the flue gas.

[0034] like Figure 1 As shown, in the technical solution of embodiment one, the dust removal structure 10 also includes a support plate and a plurality of ceramic tubes 13, the support plate is connected to the inner wall of the dust removal bin 11, the support plate has a plurality of first through holes, and the plurality of first through holes and the plurality of ceramic tubes 13 are arranged one by one. The support plate supports the ceramic tubes 13. The plurality of ceramic tubes 13 all include a limiting section and a filtering section, the diameter of the limiting section is greater than the diameter of the first through hole, the diameter of the filtering section is smaller than the diameter of the first through hole, the filtering section passes through the first through hole, the limiting section and the support plate are in contact with each other, so as to support the ceramic tubes 13, and the plurality of ceramic tubes 13 are all located above the wind equalizing structure 20, and the smoke is filtered through the filtering section after being discharged from the wind equalizing structure 20.

[0035] In some embodiments, the dust removal structure 10 further includes a flower plate, which is arranged above the ceramic tube 13 and abuts against the limiting section. The flower plate fits the inner wall of the dust removal bin 11, so that smoke is not easy to overflow from the gap between the flower plate and the dust removal bin 11. The flower plate and the support plate are fastened by screws, and the limiting section is located between the support plate and the flower plate. Under the joint action of the support plate and the flower plate, the limiting section is fixed.

[0036] In some embodiments, the flower plate has a plurality of second vias, and the plurality of second vias and the plurality of ceramic tubes 13 are arranged one by one, the limiting section has an inner diameter and an outer diameter, and the diameter of the second via is between the inner diameter and the outer diameter of the limiting section. The smoke passes through the outer wall of the ceramic tube 13 to the inside for filtration, and the filtered gas is discharged from the ceramic tube 13. Due to the function of the support plate and the flower plate, the smoke is separated from the filtered gas, and the diameter of the second via is between the inner diameter and the outer diameter of the limiting section, which enables the flower plate to abut against the limiting section, and fix the limiting section while the second via does not affect the discharge of the filtered gas.

[0037] like Figure 1 As shown, in some embodiments, the support plate and the flower plate separate the dust removal bin 11 into a clean air chamber 111 and a filter chamber 112. The dust removal bin 11 also has an ash collecting hopper 113, which is connected to the filter chamber 112 and is located below the filter chamber 112. The space above the flower plate in the dust removal bin 11 is called the clean air chamber 111, and the space below the support plate in the dust removal bin 11 is called the filter chamber 112. The filter section is located in the filter chamber 112, and the wind equalization structure is arranged in the filter chamber 112. The smoke enters from the air inlet, and after the uniformity is improved by the wind equalization structure 20, it fills the filter chamber 112, and after being filtered by the filter section, it flows into the clean air chamber 111.

[0038] like Figure 3As shown, the difference between the technical solution of the second embodiment and the first embodiment is that the air balancing structure 20 also includes a sealing plate, which is connected to the connecting plate 21, the air balancing plate 22 and the ash blocking plate 23 to seal the openings on both sides and prevent smoke from overflowing. The sealing plate is connected to the inner wall of the dust removal bin 11 to fix the air balancing structure 20. The connecting plate has a second air balancing hole, the diameter of which is larger than the diameter of the first air balancing hole 221. The second air balancing hole can improve the uniformity of the smoke while having little effect on the smoke flow rate. The ash blocking plate 23 has a group, and the ash blocking plate 23 has an inclination angle in the horizontal direction. The second end of the ash blocking plate 23 is lower than the first end, which makes the ash blocking plate 23 have an inner wall on the side of the air inlet facing the dust removal bin 11, and the ash blocking plate 23 has a third air balancing hole, and the diameter of the third air balancing hole is less than or equal to the diameter of the first air balancing hole 221. The flue gas is discharged after improving the uniformity through the third air balancing hole, and flows to the ceramic tube 13 under the rebound effect of the inner wall of the dust removal bin 11. This arrangement prevents the flue gas from directly acting on the ceramic tube 13, and at the same time, the time for the flue gas to reach the ceramic tube 13 is shortened, and the filtration rate is improved. The air equalizing plate includes a first air equalizing plate and a second air equalizing plate. The first end of the ash blocking plate 23 is connected to the first air equalizing plate, and the second end of the ash blocking plate 23 is connected to the second air equalizing plate. Since the height of the second end of the ash blocking plate 23 is lower than the first end, the size of the first air equalizing plate is larger than that of the second air equalizing plate. The number of first air equalizing holes 221 on the first air equalizing plate is more than the number of first air equalizing holes 221 on the second air equalizing plate. The angle between the first air equalizing plate and the connecting plate is between 45° and 90°. In this embodiment, the angle between the first air equalizing plate and the connecting plate is 60°. At this time, the smoke flows into the filter chamber 112 through the first air equalizing holes 221 on the first air equalizing plate. This arrangement makes it easier for the smoke to fill the entire filter chamber 112, and the filtering efficiency of the smoke is effectively improved.
