Device for Flattening of Transportation Coal in System for Drying Coal

The present invention is dispersed evenly on the coal that is fed to a multi-stage dryer from the differentiator in a multi-stage dryer to dry the coal using a reheat steam relates to a feed coal leveling to improve the drying efficiency, and a pair of first drive sprockets between the pair of first driven sprockets are spaced apart by a predetermined distance and fastened to the first chain, respectively, a first and a plurality of first transfer plate between the chain hinged, a first drive sprocket and the first driven sprocket a pair of first guide rails to the support of one horizontal the transfer plate below the associated upper second chain is provided, the first level of the first transfer plate below the lower side a first chain is connected between the drive sprocket and the first driven sprocket and a pair of second guide rails for supporting installation, the first vapor chamber for injecting a reheat steam supply in the re-opening below said upper first chain installed High, and the second steam chamber for injecting a reheat steam supply in the re-opening under the lower first chain installation, the first off-gas chamber for collecting exhaust gas on the upper first chain is provided, wherein the lower first chain a first coal dryer in the second off-gas chamber for collecting the exhaust gas is installed above; And the two pairs of the second pair of second driven sprocket and the drive sprocket is connected to each of the second chain and spaced apart by a predetermined distance, a second and a plurality of second transfer plate hinge coupled between the chain and the second the lower side is connected between the drive sprocket and the second and the second with a pair of third guide rails for supporting horizontally a transfer plate disposed under the upper second chain coupled between the driven sprocket and the second drive sprocket and second follower sprocket 2 the second is a pair of fourth guide rails for supporting the horizontal installation a transfer plate, and the third steam chamber for injecting a reheat steam supply in the re-opening below said upper second chain installation, the lower the bottom chain of claim 2, and the fourth vapor chamber installation for injecting the reheat steam supply in the re-opening under the chain, the third off-gas chamber for collecting exhaust gas on the upper second chain is provided, the exhaust gas over the lower chain A fourth off-gas the second coal dryer chamber is installed to house and to put the primary drying coal from the first coal dryer in the second coal dryer in the coal drying device consisting of such secondary drying, the said plurality of 1 at predetermined intervals on the upper surface towards the top in the feed plate and the second transfer plate body of the pillar being installed, respectively; Separator protrusion of dispersing the center of the coal pile is formed projecting in the center of the body put into the front surface towards the top of the first transfer plate and the second plate from the coal feed amount to the feeder divided left and right; And a first guide rail top and the second guide rails top and the second is fixed to the top of the third guide rail top and the fourth guide rail for supporting horizontally the transfer plate of the body both ends for supporting horizontally the first transfer plate a fixed support including a fixing member of a pair, and by flattening the coal pile to be transported from the surface towards the top of the first transfer plate and the second transfer plate at a constant height through the first transfer plate and the second transfer plate the reheat steam is injected to the coal particles to be evenly in contact with the surface. The invention evenly distributes the coal pile in order to take dry effectively the moisture contained in the coal as a reheat steam of high temperature is injected through the through hole through a plurality of the transfer plate, while conveying the coal pile over a plurality of the transfer plate to transfer the coal and planarized by the a reheat steam of high temperature can be easily to ensure that contact prevents incomplete combustion of coal to fuel the coal inside the water removal remaining on the outside of the thermal power plants, the improvement of the coal heat and pollutants in the coal particles minimize emissions and to reducing the natural firing rate in accordance with decreasing water content of the coal and, increasing the utilization of the small lower coal demand improve the stability of the coal supply.
