    摘要： The present invention pertains to the indirect heating or cooling of a drum reactor by the exchange of heat from a heat carrier medium. The heat carrier medium is fed to one or more annular distribution chambers fixedly disposed about a stationary outer wall or jacket, thence through openings in the jacket into the annular space between the jacket and the rotatable drum wall, and finally out to one or more annular collection chambers. The distribution and collection chambers are spaced apart from each other and cause the heat carrier medium to flow longitudinally along the drum for more efficient heat exchange. In addition, the various inlet and exit ports of the alternate distribution chambers are radially spaced from each other such that the heat carrier flow is both longitudinal and rotational about the drum reactor.

    摘要： A device and method for drying fine particulate. A parallel flow rotary drum dryer is used to dry the particulate material. There is a combustion chamber for the burner, located upstream of the dryer inlet, and the burner flame is limited to the combustion chamber so the fine particulate material does not come into direct contact with the burner flame. The output from the dryer passes through a knock-out box including a baffle system with a plurality of narrow gaps to create a pressure drop to slow down the gas flow and enable the entrained fine mesh dry particulate to drop out through a bottom outlet before the effluent gas is sent to the dust collection/air filtration system.

    摘要： To provide a drying method for terephthalic acid and a horizontal rotary dryer allowing easy performance of mass processing of the terephthalic acid and enabling size reduction by improving drying performance of the dryer. In a method of drying terephthalic acid by using a horizontal rotary dryer, a rotating shell is rotated to make a critical speed ratio α defined by expression 1 and expression 2 become 17 to less than 80% to dry the processing material, Vc=2.21D½  Expression 1 α=V/Vc·100  Expression 2 wherein Vc indicates a critical speed (m/s) of the rotating shell, D indicates an inside diameter (m) of the rotating shell, α indicates the critical speed ratio (%) of the rotating shell, and V indicates a rotation speed (m/s) of the rotating shell.

    摘要： A technology for material separation is provided. The technology enables an output of a first material from a rotary lifter. The technology enables a direction of a fluid stream onto the first material in flight based on the output of the first material such that the first material is separated into at least a second material and a third material. The technology enables a conveyance of the second material away from the rotary lifter. The technology enables a removal of the third material via a vacuum port.

    摘要： Provided is an indirectly heating rotary dryer which has achieved enhanced energy-saving performance by reducing heating tubes non-contacting with material to be dried and reducing power required for rotation even when a hold up ratio is increased.Specifically provided is an indirectly heating rotary dryer having four partition walls 16 extended respectively along an shaft center C in an inner space of a rotating shell 10 at angle intervals of 90 degrees in the vertical and horizontal directions. The four partition walls 16 partition the inner space of the rotating shell 10 at a lateral section of the rotating shell 10 into four approximately-sector-shaped small spaces K respectively extended along the shaft center C. Heating tubes 11 are aligned in the rotating shell 10 in three lines extended respectively in parallel to the shaft center C of the rotating shell 10. The heat tubes 11 heat and dry the material H to be dried by supplying heated steam to the heating tubes 11 and performing heat exchange with the material H to be dried in the rotating shell 10.
