PROBLEM TO BE SOLVED: To solve the problem of conventional dust recovering equipment that much cost and time are necessary when dried dust of a high temperature is recovered since a special recovering bag having heat resistance is used or it is necessary to satisfactorily cool the dried dust and recover the cooled dust. SOLUTION: This dust recovering equipment 1 is provided with a primary recovering vessel 11 into which the dried dust is introduced, a secondary recovering vessel 12 in which the recovering bag 13 for filtering a gas and housing dust is arranged, a recovering pipe 14 for circulating the dried dust from the vessel 11 to the vessel 12, an air supplying system 15 for supplying cooling air to the vessel 11 and at least one of a supply source 16 for supplying the cooling air to the system 15 and an exhaust source 17 for exhausting the gas in the vessel 12. The dust of high temperature is cooled in a short period of time and the cooled dust is efficiently recovered. The cost necessary for recovering the dust is reduced by using a paper-made recovering bag, for example. COPYRIGHT: (C)2004,JPO
