Description

Technical Field

[0001] The utility model belongs to the field of dust removal equipment and relates to a bag filter for treating flue gas in pyro-refining. Background Technique

[0002] The bag filter for treating flue gas in pyro-refining is a device specifically for treating the flue gas generated in the pyro-refining process. The bag filter mainly uses a filtering material (cloth bag) to filter and separate the particulate matter in the flue gas. After the dusty flue gas enters the dust collector and passes through the cloth bag, the particulate matter is blocked on the surface of the cloth bag, while the purified gas passes through the cloth bag and is discharged. As the filtration progresses, the dust layer on the surface of the cloth bag gradually thickens. When the resistance reaches a certain value, the dust cleaning system is started to remove the dust on the surface of the cloth bag and restore the filtration performance of the dust collector.

[0003] The reverse blowing system mainly uses reverse air flow to impact the cloth bag to make the attached dust fall off. However, for some dust layers with relatively high viscosity or thickness, the reverse blowing force may not be sufficient to completely remove the accumulated dust on the cloth bag. Without a follow-up mechanical beating mechanism, it may lead to more dust residues on the surface of the cloth bag, reduce the filtration efficiency, increase the system resistance, and affect the normal operation life of the dust collector. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bag filter for treating flue gas in pyro-refining with reasonable space utilization in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] A bag filter for treating flue gas in pyro-refining, characterized in that it includes a dust removal chamber, a storage horizontal plate is fixedly connected to the upper side of the inner end of the dust removal chamber, a plurality of cloth bag bodies are installed at the lower end of the storage horizontal plate, a plurality of upper grooves are opened at the lower end of the storage horizontal plate, a rotating shaft member is fixedly connected to the upper inner wall of the upper groove, a vertically swinging vertical rod is rotatably connected to the lower end of the rotating shaft member, a plurality of material-patting air bags are symmetrically fixedly connected to the left and right ends of the vertically swinging vertical rod, protruding cross bars are symmetrically fixedly connected to the left and right inner walls of the upper groove, a force-applying spring is fixedly connected to one end of the two protruding cross bars close to each other, and an elastic ball is connected to one end of the two force-applying springs close to each other.

[0007] In the above-mentioned bag filter for treating flue gas in pyro-refining, the plurality of vertically swinging vertical rods are located between two adjacent cloth bag bodies, and the material-patting air bags are in contact with the outer wall surface of the cloth bag body.

[0008] In the above-mentioned bag filter for treating pyrorefining flue gas, the two corresponding elastic balls are respectively located on the left and right sides of the corresponding vertically swinging vertical rod, and the elastic balls are in contact with the vertically swinging vertical rod.

[0009] In the above-mentioned bag filter for treating pyrorefining flue gas, an air inlet is fixedly connected to the left end of the dust removal chamber, and an air outlet is fixedly connected to the upper end of the dust removal chamber.

[0010] In the above-mentioned bag filter for treating pyrorefining flue gas, an inverse blowing and dust cleaning device is fixedly connected to the upper side of the inner end of the dust removal chamber, and the inverse blowing and dust cleaning device is located directly above the placing cross plate.

[0011] In the above-mentioned bag filter for treating pyrorefining flue gas, a dust storage hopper is fixedly connected to the lower end thereof, and a dust discharge port is fixedly connected between the dust removal chamber and the dust storage hopper.

[0013] Compared with the prior art, during the process of flue gas introduction and inverse blowing of the inverse blowing and dust cleaning device in this bag filter for treating pyrorefining flue gas, air flow output will be generated. Along with the air flow output, the driving force can be utilized to generate a shaking force on the vertically swinging vertical rod. When the vertically swinging vertical rod shakes, multiple material beating air bags outside it can generate a mechanical beating force on the surface of the cloth bag body, assisting in shaking off the attachments on the surface of the cloth bag body, thereby ensuring its dust cleaning effect and extending its service life. Moreover, during the process of the vertically swinging vertical rod fluctuating with the air flow, the rotating shaft part on the upper side of the vertically swinging vertical rod can make the vertically swinging vertical rod in a state of being able to rotate. And when the vertically swinging vertical rod rotates, it can be in contact with the elastic balls on both sides in the upper groove. The force-applying spring between the elastic ball and the protruding cross bar is used to expand the rebound repetition path of the vertically swinging vertical rod, effectively increasing the beating frequency of the vertically swinging vertical rod, thereby ensuring its dust cleaning effect.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0021] As Figure 1 As shown in FIG. -3, the bag filter for treating pyrometallurgical refining flue gas of the present invention includes a dust removal bin 1. The upper side of the inner end of the dust removal bin 1 is fixedly connected with a horizontal storage plate 2. A plurality of cloth bag bodies 3 are installed at the lower end of the horizontal storage plate 2. A plurality of upper grooves 4 are opened at the lower end of the horizontal storage plate 2. The upper inner wall of the upper groove 4 is fixedly connected with a rotating shaft member 5. The lower end of the rotating shaft member 5 is rotatably connected with a vertically swinging vertical rod 9. A plurality of material-patting airbags 10 are symmetrically and fixedly connected to the left and right ends of the vertically swinging vertical rod 9. The left and right inner walls of the upper groove 4 are symmetrically and fixedly connected with protruding cross bars 8. The mutually approaching ends of the two protruding cross bars 8 are fixedly connected with a biasing spring 6. The mutually approaching ends of the two biasing springs 6 are connected with an elastic ball 7.

[0022] The plurality of vertical swinging vertical rods 9 are located between two adjacent cloth bag bodies 3 , and the material beating airbags 10 are in contact with the outer wall surface of the cloth bag body 3 .

[0023] The two corresponding elastic balls 7 are respectively located on the left and right sides of the corresponding vertical swing rod 9, and the elastic balls 7 and the vertical swing rod 9 are in contact with each other.

[0024] The left end of the dust removal bin 1 is fixedly connected with an air inlet 11 , and the upper end of the dust removal bin 1 is fixedly connected with an air outlet 14 .

[0025] A back-blowing dust cleaner 16 is fixedly connected to the upper inner end of the dust removal bin 1 , and the back-blowing dust cleaner 16 is located directly above the storage horizontal plate 2 .

[0026] The lower end is fixedly connected with an ash storage hopper 13 , and an ash discharge port 12 is fixedly connected between the dust removal bin 1 and the ash storage hopper 13 .

[0027] A discharge inclined panel 15 is fixedly connected to the lower inner wall of the dust removal bin 1 , and the discharge inclined panel 15 is located outside the dust discharge port 12 .

[0028] In this scheme, when the dust-containing flue gas is sucked into the dust removal bin 1 and passes through multiple bag bodies 3, the dust is trapped on the surface of the bag body 3, and the purified gas is discharged through the air outlet 14 on the filter bag. As the filtration proceeds, the dust layer on the surface of the bag body 3 gradually thickens and the resistance also increases accordingly. When the resistance reaches a certain value, the back-blowing cleaner 16 is started to back-blow the bag body 3 for cleaning operation to restore the filtering performance of the filter bag. The cleaned dust falls into the ash storage hopper 13 and is discharged out of the dust removal bin 1. In the process of flue gas introduction and back-blowing of the back-blowing cleaner 16, air flow output will be generated. The driving force of the air flow output can be used to generate a shaking force on the vertical swing vertical rod 9. When the vertical swing vertical rod 9 shakes, the multiple material-beating air bags 10 outside it can generate mechanical beating force on the surface of the bag body 3 to assist in shaking off the attachments on the surface of the bag body 3. The vertical swing vertical rod 9 can be rotatable during the fluctuation of the airflow, and the vertical swing vertical rod 9 can be in contact with the elastic balls 7 on both sides of the upper groove 4 during the rotation. The force spring 6 between the elastic balls 7 and the protruding cross bar 8 can expand the rebound repetitive path of the vertical swing vertical rod 9, so that the beating frequency of the vertical swing vertical rod 9 is effectively increased, thereby ensuring the cleaning effect. At the same time, the dust after cleaning flows into the ash storage hopper 13 for storage through the ash discharge port 12. During the dust discharge process, a discharge inclined panel 15 can be provided at the lower inner wall position of the dust removal bin 1. The discharge inclined panel 15 effectively guides the shaken dust to the ash discharge port 12 accurately, which is beneficial to improving the dust discharge effect in the dust removal bin 1 and is not prone to residual risks.

[0029] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
