The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of sintering flue gas desulfurization ash silo of the utility model example structure schematic diagram, comprise main cabin body 1, main cabin body 1 is respectively equipped with circulation hopper 2 and outer hopper 3 below, the bottom of circulation ash bucket 2 is provided with vibrating motor 1, circulation ash bucket 2 outlet at bottoms successively with manually gate valve 1, star-shaped dust-discharging valve 1 is connected with screw feeder 13, the outlet of screw feeder 13 is circulating ash interface 14, screw feeder 13 can accurate-metering enters the circulating ash quantity of mixing can, realize quantitative delivery cycle ash, circulating ash is gone to slurries system mixing can by circulating ash interface, recycle.
The top of main cabin body 1 is respectively equipped with Desulphurization entrance 4, roof scrubber 5, high charge level meter 6 and safety relief valve 7, and the bottom of main cabin body 1 is provided with low level-sensing device 9, accurately to grasp the storage ash situation of desulfurization ash silo.The top of main cabin body 1 is also provided with manhole 8.
The utility model unites two into one desulfurization ash silo and circulation powder storehouse, and the Desulphurization entrance 4 that Desulphurization is delivered to desulfurization ash silo top from sack cleaner ash bucket enters Desulphurization storage and deposits.The reentrainment of dust producing during the charging of desulfurization ash silo, purifies qualified discharge by roof scrubber.By high charge level meter 6 and low level-sensing device 9, carry out the metering of ash amount.Once desulfurization ash silo internal pressure is excessive, safety relief valve 7 starts pressure release, to guarantee safety.When desulfurization ash silo breaks down, guaranteeing safe in the situation that, maintainer can be entered and in storehouse, be carried out upkeep operation by manhole 8.Regularly rapping of electric motor of shaker 1 bulkhead, prevents that the sticky wall of circulating ash from stopping up, and guarantees that under circulating ash, ash is smooth and easy.
