Wherein, the box sets up in the top of putting out a fire laboratory 9, and the one end of dust removal box 1 is provided with output port 11, and the other end of dust removal box 1 is provided with input port 12. One end of the dust removing pipeline 2 is connected with the input port 12 of the dust removing box body 1, and the other end of the dust removing pipeline 2 is connected with the inside of the fire extinguishing laboratory 9. The exhaust system 3 is arranged at the outlet 11 of the dust removal box 1. The first filter layer 4 is disposed in the dust removal box 1. The second filter layer 5 is arranged in the dust removal box body 1, the second filter layer 5 is positioned between the first filter layer 4 and the exhaust system 3, the diameter of the filter holes of the second filter layer 5 is smaller than that of the first filter layer 4, and the diameter of the filter holes of the second filter layer 5 is smaller than that of the superfine dry powder. The sundry collecting part 6 is arranged at the bottom of the dust removing box body 1 and is positioned below the first filter layer 4. The superfine dry powder recovery part 7 is arranged at the bottom of the dust removing box body 1 and is positioned below the second filter layer 5.
The dust collector is used in superfine dry powder fire extinguishing laboratory 9 that this embodiment provided, during operation, exhaust system 3 starts outwards to exhaust, and then make the air in the fire extinguishing laboratory 9 inhale dust removal box 1 through dust removal pipeline 2, the air is at first through first filter layer 4, first filter layer 4 filters the big granule impurity (the big granule that the burning produced) in the air and gets rid of, and superfine dry powder that the granularity is less moves to second filter layer 5 position along with the air through first filter layer 4, under the filter action of second filter layer 5 (the filtration pore diameter of second filter layer 5 is less than 10 um), superfine dry powder is separated by second filter layer 5, and then make superfine dry powder and gas separation, gas is discharged from dust removal box 1's delivery outlet 11, and big granule impurity and superfine dry powder are then collected by debris collection portion 6 and superfine dry powder recovery portion 7 respectively, and then make super dust collector realize the dry collection to superfine dry powder in the dust collector of dust removal, so that the recovery and recycle of superfine dry powder. In addition, the first filter layer 4 is used for filtering out some large-particle impurities, so that the purity of the recovered superfine dry powder is improved.
Optionally, the first filter layer 4 may be made of sponge, cotton, etc., and the diameter of the filter hole of the first filter layer 4 needs to be larger than the particle diameter of the superfine dry powder (the particle diameter of the superfine dry powder is about 10 um), so that the first filter layer 4 can filter and remove large particles in air, and simultaneously, the air and the superfine dry powder can pass through smoothly.
The second filter layer 5 can adopt a metal mesh screen with a filter hole diameter of 8um, and the second filter layer 5 can be used for completely blocking the superfine dry powder in the air at one side of the second filter layer 5 away from the output port 11, so that the superfine dry powder falls into the superfine dry powder recovery part 7 below, and the recovery of the superfine dry powder is realized.
