风道式蓄热装置;DUCT TYPE ACCUMULATOR

摘要

提供一种可于短时间内且迅速地完成全部蓄热材料之交换作业的风道式蓄热装置。风道式蓄热装置系具备有：垂直风道2，其在上部连接有上部风道3，并且在下部连接有下部风道4，且至少至下部风道上方为止收纳有球状蓄热材料11，经由球状蓄热材料而于上部风道与下部风道之间以交替之方式流通燃烧用空气A及废气B；供给料斗12，其设置在垂直风道上，用于将球状蓄热材料供给至该垂直风道内部；上部闸门14，其以开闭自如之方式设置在供给料斗与垂直风道之间，于关闭之后，用于将球状蓄热材料保持在供给料斗内，并且于开放之后，用于自供给料斗将球状蓄热材料投放至垂直风道内部；及下部闸门15，其以开闭自如之方式设置在垂直风道下端2b，于关闭之后，将球状蓄热材料保持在垂直风道内，并且于开放之后，自垂直风道内部将球状蓄热材料加以排出。;This invention provides for a duct type accumulator capable of rapidly completing an exchange work of whole amount of the accumulating members in a short time. ;[Means] ;A duct type accumulator includes a vertical duct 2 having an upper part and lower part, the upper part being connected with an upper duct 3 and the lower part being connected with a lower duct 4, the vertical duct holding granular accumulating members 11 up to a height at least above the lower duct, and the vertical duct in which a combustion air A and exhaust gas B are alternately flown between the upper duct and lower duct through the granular accumulating members, a supply hopper 12 provided above the vertical duct and supplying the granular accumulating members into the vertical duct, an upper gate 14 provided between the supply hopper and the vertical duct, the upper gate keeping the granular accumulating members in the supply hopper in a closed position and charging the vertical duct with the granular accumulating members from the supply hopper in an open position, a lower gate 15 provided underneath a lower end 2b of the vertical duct, the lower gate keeping the granular accumulating members in the vertical duct in a closed position and discharging the granular accumulating members from the vertical duct in an open position.
