本发明涉及一种用于防止在多级干燥器中由煤氧化引起的转移煤自发燃烧的装置，用于使用再热蒸汽干燥煤，其中煤被注入到用于装载，转移，转动 并且将多个转印板的表面上的煤桩从煤恒定进料器通过粉碎机落下。 该装置包括：在第一上链上设置用于收集废气的第一排气室和用于收集废气的第二排气室的第一煤干燥器，设置在第一下链上; 并且在第二上链上设置有用于收集废气的第三排气室的第二煤干燥器，并且在第二下链上设置用于收集废气的第四排气室。 每个第一转印辊铰接到第一转印板和第一链的两侧中心之间的空间。 将用氮气和/或饱和蒸汽的再热蒸汽注入由第一和第二转印板转移的煤，以防止煤的干燥和转移时的自燃。 该装置允许在用转印板装载，转移，转动和堆放煤层时转移板的平稳运行，以提高煤的干燥效率，减小煤干燥装置的尺寸，并且在转移期间最小化灰尘 的煤。

When the present invention is by using a reheat steam to through a differentiator in the multi-stage of the dryer to dry the coal loading the coal pile to a plurality of transfer plate surface from coal quantitative feeder to feed the coal being fed to the transfer, the transfer device for rotating and falling It relates to a device for preventing the spontaneous combustion due to oxidation of the coal, a pair of first drive sprockets and a pair of first driven sprockets are spaced apart by a predetermined distance and fastened to the respective first chain, between the first chain coupled a plurality of first transfer plate is hinged, a first drive sprocket and the first upper first chain the first guide rail a pair of horizontal supporting the first transfer plate upper side below connected between the driven sprocket is installed in, claim is installed a second guide rail pair of horizontal support for the lower first transport plate under the lower first chain connected between the first drive sprocket and first follower sprocket, fed from the upper first opening material under chain first vapor chamber for injecting the reheat steam is provided, it said second vapor chamber has first to be installed, collects the upper flue-gas on the first chain 1 for injecting a reheat steam supplied from the lower side first opening material under chain a first and a second coal drier off-gas chamber to the exhaust gas chamber is provided, the exhaust gas trapped above the lower side chain installed first; And the pair of second drive sprockets and a pair of second driven sprockets are spaced apart by a predetermined distance each being connected by a second chain, and the second chain a plurality of second transfer plate between the coupling hinge, the second a pair of third guide rails is provided, the lower the coupled between the second drive sprocket and the second driven sprockets to the horizontal support of the second transfer plate upper side under the upper second chain is connected between the drive sprocket and the second driven sprocket the fourth guide rail a pair of horizontal support to the lower side second transfer plate below the second chain is installed, the third steam chamber for injecting a reheat steam supplied from the upper second opening material under the chain is installed, the claim for injecting the reheat steam supplied from the heat re-under lower second chain four steam chambers are installed, the third off-gas chamber for collecting the exhaust gas on the upper second chain is provided, for collecting the exhaust gas on the lower side chain the fourth off-gas chamber is installed, the second comprises a coal dryer, wherein the first transfer rollers respectively, between the first transfer plate sides the center of the first chain are hinged, the first auxiliary to the left and right sides of the first feed roller the rollers are coupled respectively hinged to the side of the first transfer plate, the second transfer plate either side second transfer respectively between the central and the second chain roller is hinged a second auxiliary left and right and the second transport roller the rollers are coupled respectively hinged to the side of the second transfer plate, the bottom along the first guide bar side from the first drive sprocket top to rotate the lower first transport plate separated from the second guide rail in one direction and not rising to is provided, along the second guide bar side from the first driven sprockets lower portion for supporting rotation of the first transfer plate separated the upper from the first guide rail in one direction is lowered and installed to the top, from the fourth guide rail rotating the separated lower side second transfer plate in one direction and a third guide for supporting elevated bar along the side in the second drive sprocket top is provided to the lower portion, a direction of the upper second transfer plate is separated from the third guide rail the bar fourth guide for supporting rotating and falling into second driven from sprocket bottom along the side, and includes being installed to the upper and comprises a coal quantitative feeder for feeding a fixed amount of coal to the surface towards the top of the first transfer plate , to put the first primary drying coal from the coal dryer in the second coal dryer in the coal drying apparatus using a reheat steam made to dry the secondary, fed through the reheat steam supply pipe for reheating the steam generated at said reheater and, the nitrogen supplied through the supply pipe for the nitrogen in the nitrogen supply, and supplying saturated steam generated by the steam generator through a saturated steam supply pipe saturated, the reheat steam supply pipe, a nitrogen feed pipe, and the saturated steam supply pipe is connected to the four-way valve , a four-way valve is transferred to a nitrogen-saturated steam or nitrogen or the saturated vapor feed to the first vapor chamber to the fourth chamber via the steam supply pipe and the steam, the first transfer plate and the second transfer plate with a reheat steam in the process of drying and transporting the coal to the coal injection will prevent the spontaneous combustion of coal. The present invention by preventing ignition or spontaneous combustion, etc. of coal that can occur when drying or transporting the coal maximize the use of a coal drying device, loading and transferring, rotating and dropping the coal pile of a plurality of the transfer plate to transfer plate sikimyeo by the operating so smoothly increase the drying efficiency of the coal, the coal on the plurality of the transfer plate, with improved reliability of the operation of the coal drying apparatus for coal drying device, it is possible to minimize the generation of dust of the coal transported to the compact implementation balancing the density of the coal pile to be transported in order to while conveying the pile dried effectively take away the moisture contained in the coal by high-temperature reheat steam in injected via a hole through the plurality to the transport plate and equalization and flattened by the high temperature in the coal particles reheat steam can prevent the incomplete combustion of coal to remove water remaining in the fuel used is coal and out of the thermal power plant to be easily contacted, which demand a better use of the small lower coal improve the stability of the coal supply will be.
