Abstract

The invention discloses a dust collector side air inlet device and a bag dust collector. The side air inlet device comprises a first air flow diffusion chamber and a second air flow diffusion chamber.The first air flow diffusion chamber is provided with a first air inlet and a first air outlet. The second air flow diffusion chamber is provided with a second air inlet and a second air outlet. Thefirst air inlet is used for receiving the exhaust gas. The first air outlet is connected to the second air inlet. The second air outlet is connected to a dust collector. A first porous air distribution plate is arranged at the first air outlet. A second porous air distribution plate is arranged at the second air outlet. The area of the first air inlet is less than that of the first air outlet. Thearea of the second air inlet is less than that of the second air outlet. Through the air flow diffusion chambers and the porous air distribution plates, the air speed at the inlet of the dust collector is greatly reduced, the inlet air flow is evenly distributed, the eddy current is reduced, the secondary dust lifting is reduced, the filter bag scouring is reduced and the pressure loss of the dust collector is reduced so that the energy consumption of the dust removal system is reduced and the service life of the filter bag is prolonged.

Example Embodiment

[0021] Reference figure 1 with figure 2 As shown, a bag filter includes a dust removal chamber 1, a dust collection chamber 2, and a side air inlet device 3.

[0022] The side air inlet device 3 includes a first air diffusion chamber 31 and a second air diffusion chamber 32. The first air diffusion chamber 31 is provided with a first air inlet 311 and a first air outlet 312, and the second air diffusion chamber 32 is provided with a second air The air inlet 321 and the second air outlet 322, the first air inlet 311 is provided with a flange 3111 for connecting the exhaust flue, the first air outlet 312 and the second air inlet 321 are of equal size and butt each other, and the second air outlet 322 and The sides of the dust removal chamber 1 are butted, the first air outlet 312 is provided with a first porous air equalizing plate 313, and the second air outlet 322 is provided with a second porous air equalizing plate 323,

[0023] The cross section of the first air diffusion chamber 31 is gradually reduced along the air inlet direction. The specific first air diffusion chamber 31 has a horizontal wedge structure, the first air inlet 311 is arranged on the side of the first air diffusion chamber 31, and the first air outlet 312 The area of the first air outlet 312 is larger than twice the area of the first air inlet 311, and the total area of the first air equalizing plate 313 is larger than that of the first air diffuser. The area of an air inlet 311.

[0024] The cross-section of the second air diffusion chamber 32 is gradually reduced along the air inlet direction. The specific second air diffusion chamber 32 has a vertical wedge-shaped structure, the second air inlet 321 is provided on the bottom surface of the second air diffusion chamber 32, and the second air outlet 322 The area of the second air outlet 322 is larger than twice the area of the second air inlet 321, and the total area of the second air equalization plate holes 323 is larger than that of the second air inlet 321. The area of the tuyere 321.

[0025] The dust collection chamber 1 is roughly a cuboid with a filter bag inside; the dust collection chamber 2 is roughly cone-shaped, which is set at the bottom of the dust collection chamber 1 and communicates with the dust collection chamber 1, and the side of the dust collection chamber 1 is provided with a third air inlet, and The third air inlet roughly covers the side of the dust removal chamber 1, and the third air inlet and the second air outlet 322 are of the same size and butt with each other.

[0026] When working, the dust-containing flue gas sequentially passes through the first air diffusion chamber 31 and the second air diffusion chamber 32 and then enters the dust removal chamber, passes through the air diffusion chamber and the porous air equalizing plate, which can greatly reduce the inlet wind speed of the dust collector and evenly distribute the inlet air flow , Reduce eddy current, reduce secondary dust, reduce filter bag scouring, reduce dust collector pressure loss, thereby reducing the energy consumption of the dust removal system and extending the service life of the filter bag.

[0027] The above are only preferred embodiments of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is to say, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification shall still belong to the present invention. The scope of patent coverage.
