Technical Field

The utility model relates to the technical field of waste gas dust removal equipment, in particular to waste gas dust removal equipment for desulfurization and denitrification.

Background Art

Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology used in the chemical industry that produces a lot of nitrogen oxides and sulfur oxides. The waste gas dust removal equipment used for desulfurization and denitrification refers to the equipment that separates dust from the flue gas, also called a dust collector or dust removal equipment.

When using existing waste gas dust removal equipment for desulfurization and denitrification, the mesh plates are mostly fixed and difficult to remove from the equipment. It is difficult to replace or clean the mesh plates after long-term use, resulting in increasingly poor dust removal. Moreover, most dust removal equipment is fixed and difficult to move as needed, making the dust removal range relatively limited.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3. The utility model provides a technical solution: a waste gas dust removal device for desulfurization and denitrification, including a dust removal device 1, an air inlet pipe 4 is connected to one side of the dust removal device 1, and an air outlet pipe 5 is connected to the other side of the dust removal device 1. A filter frame 17 is slidably connected in the dust removal device 1, and a filter screen 18 is arranged in the filter frame 17. A top plate 3 is connected to the filter frame 17, and a fixing rod 19 is symmetrically arranged on the bottom end surface of the top plate 3. A fixing groove 25 is provided on one side of the dust removal device 1 close to the fixing rod 19, and semicircular blocks 22 are symmetrically arranged on both sides of the fixing groove 25, and second sliding blocks 23 are symmetrically arranged on both sides of the semicircular block 22. Second slide grooves 20 are symmetrically provided on both sides of the semicircular block 22. The dust removal device 1 is symmetrically provided with fixed frames 8 on both sides, and a fixing mechanism is provided in the fixed frame 8. The fixing mechanism includes a threaded rod 7, which is threadedly connected to the fixed frame 8. A slide plate 12 is provided at one end of the fixed frame 8, and a first slide groove 9 is symmetrically opened in the fixed frame 8. First sliding blocks 10 are symmetrically arranged on both sides of the slide plate 12, and a connecting rod 11 is symmetrically arranged on one side of the slide plate 12. An inner cavity 13 is opened near the fixed frame 8 of the dust removal device 1, and a connecting plate 15 is slidably connected in the inner cavity 13. One side of the connecting plate 15 is fixedly connected to the connecting rod 11, and an insertion rod 14 is symmetrically arranged on the other side of the connecting plate 15. Slots 16 are symmetrically opened on the sides of the filter frame 17, and the insertion rod 14 is adapted to the slot 16.

Specifically, the first slider 10 is adapted to the first slide groove 9 and is slidably connected. A rotating block 6 is provided at the other end of the threaded rod 7. Rotating the rotating block 6 drives the threaded rod 7 to rotate. Under the limiting action of the first slider 10 and the first slide groove 9, the slide plate 12 slides back and forth, and at the same time drives the connecting plate 15 to slide in the inner cavity 13, thereby driving the insertion rod 14 to insert into or move away from the slot 16.

Specifically, a plurality of springs 21 are connected between the bottom end of the semicircular block 22 and the dust removal equipment 1, and semicircular grooves 24 are provided on both sides of the fixed rod 19. The semicircular block 22 is adapted to the semicircular grooves 24, and the fixed rod 19 is inserted into the fixed groove 25. The fixed groove 25 squeezes the second slider 23. Under the cooperation of the second slider 23 and the second slide groove 20, the semicircular block 22 squeezes the spring 21. When the semicircular block 22 moves to a position corresponding to the semicircular groove 24, the second slider 23 is inserted into the semicircular groove 24, which plays a role of fixing and limiting the fixed rod 19.

Specifically, a handle 2 is provided on the top plate 3 to facilitate lifting the filter frame 17 out of the dust removal device 1 for disassembly and cleaning.

Specifically, a groove matching the bottom of the filter frame 17 is provided at the bottom of the dust removal device 1 to facilitate positioning of the filter frame 17 when it is placed in the filter frame 1 .

A specific application example of this embodiment is:

When the device is in use, the filter frame 17 is placed into the dust removal device 1 through the handle 2, and the fixing rod 19 is inserted into the fixing groove 25. The fixing groove 25 squeezes the second slider 23. Under the cooperation of the second slider 23 and the second slide groove 20, the semicircular block 22 squeezes the spring 21. When the semicircular block 22 moves to a position corresponding to the semicircular groove 24, the second slider 23 is inserted into the semicircular groove 24, which plays a role in fixing and limiting the fixing rod 19. At this time, 17 also corresponds to the bottom groove inside the dust removal device 1. The rotating block 6 drives the threaded rod 7 to rotate, and the first slider 1 0 and the limiting action of the first slide groove 9, the slide plate 12 slides forward, and at the same time drives the connecting plate 15 to slide in the inner cavity 13, thereby driving the insertion rod 14 to insert into the slot 16, and fixing and limiting the filter frame 17. When the filter frame 17 needs to be taken out for cleaning, the rotating block 6 is rotated in the reverse direction to drive the insertion rod 14 to slide out of the slot 16, and the fixed limit of the filter frame 17 is released. At this time, the filter frame 17 is pulled up by the handle 2, and the fixing rod 19 squeezes the semicircular groove 24 to slide inward, so that the filter frame 17 can be completely taken out of the dust removal device 1, and the next step of cleaning is carried out.
