Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

As shown in fig. 1, a biomass bunker dust prevention system comprises a roller shutter type closing door 2, a first air pipe 3, a cyclone separator 4, a bag-type dust collector 7, an induced draft fan 11 and a recovery device.

One side of the biomass bin 1 is provided with a feeding platform, and the roller shutter type sealing door 2 is arranged on the feeding hole of the biomass bin 1 and is opposite to the feeding platform.

The one end of first tuber pipe 3 is connected with three branch pipes that induced draft, is middle branch pipe 32, left branch pipe 31, right branch pipe 32 respectively, and middle branch pipe 32 is installed in the intermediate position of living beings feed bin 1, and left branch pipe 31 is installed in the left side of living beings feed bin 1, and right branch pipe 32 is installed on the right side of living beings feed bin 1, and three branch pipes that induced draft make the interior even negative pressure that forms of living beings feed bin 1. The air inlet ends of the middle branch pipe 32, the left branch pipe 31 and the right branch pipe 32 are respectively provided with a filter screen, and the aperture of each filter screen is not more than 10 mm. The filter screen is made of stainless steel materials, and can filter biomass fuel with the diameter larger than 10 mm.

The other end of the first air pipe 3 is connected with a cyclone separator 4; the air outlet of the cyclone separator 4 is connected with a bag-type dust collector 7 through a second air pipe 6. In order to guarantee the dust removal effect, the bag-type dust remover 7 is provided with two in parallel, the air outlet of the bag-type dust remover 7 is connected with the induced draft fan 11 through the third air duct 10, the induced draft fan 11 is a centrifugal fan and used for exhausting air to form negative pressure, the air outlet of the induced draft fan 11 is provided with the fourth air duct 12, and the fourth air duct 12 is used for exhausting air.

The recovery device comprises a spiral feeder 13, a first unloader 5, a second unloader 8, a third unloader 9 and a dust tester 15. The discharge end of the spiral feeder 13 is connected with the biomass bin 1, the sealing performance of the spiral feeder 13 is good, and dust is not easy to escape. The first discharger 5 is connected to the cyclone 4 and the feed screw 13, respectively. The second discharging machine 8 and the third discharging machine 9 are respectively connected with the bag-type dust collector 7 and the spiral feeding machine 13. Wherein, dust tester 15 installs in living beings feed bin 1 for the dust content in the living beings feed bin 1 of real-time detection.

The first air duct 3, the second air duct 6, the third air duct 10 and the fourth air duct 12 are all carbon steel tubes or stainless steel tubes.

The first unloading machine 5, the second unloading machine 8 and the third unloading machine 9 are all star-shaped unloading machines.
