Detailed Description
A secondary dust removal box of a roasting shaft furnace as shown in figure 1 and figure 2, which is characterized in that: the dust collection box comprises a box body 1 and a dust collection plate 2 arranged in the box body 1, wherein the top of the box body 1 is provided with an air inlet 1-1, the side wall of the box body 1 is provided with an air outlet 1-2, and the air outlet 1-2 is connected with an induced draft fan 3; the dust removal plate 2 comprises a plate body 2-1 obliquely arranged between the air inlet 1-1 and the air outlet 1-2, a water spray pipe 2-2 transversely arranged at the upper end of the plate body 2-1 and a dust exhaust pipe 2-3 transversely arranged at the lower end of the plate body 2-1, spray openings 2-21 are uniformly distributed on the water spray pipe 2-2, and a dust collection opening 2-31 is arranged at the top of the dust exhaust pipe 2-3; the upper end of the plate body 2-1 is connected to the upper wall of the box body 1, and a gas flow channel is formed between the lower end of the plate body 2-1 and the inner wall of the box body 1; a baffle plate 2-4 is arranged on the side part of the plate body 2-1; the dust exhaust pipe 2-3 is connected with a vertical pipe 2-32 extending out of the box body 1; and the exhaust port 1-2 is provided with a filter screen 1-21.
The working process of the utility model is as follows:
the smoke filtered by the water film dust collector enters the box body 1 from the air inlet 1-1, and the draught fan 3 leads the smoke out of the air outlet 1-2; when the flue gas flows in the box body 1, the spraying ports 2-21 of the spraying pipes 2-2 spray water towards the plate body 2-1, a flowing water curtain is formed on the plate body 2-1, the smoke dust in the flue gas is adsorbed on the water curtain after contacting the water curtain and flows along with the water curtain to enter the dust exhaust pipe 2-3 from the dust collection port 2-31, finally the smoke dust is discharged out of the box body 1 through the vertical pipe 2-32, and a small amount of adsorbed smoke dust is blocked by the filter screen 1-21.
