    摘要: A solid-liquid separation device of the present invention is a solid-liquid separation device, in which a filtration belt (1), a seal belt (8), and a squeezing belt (15) are wound around an outer circumference of a separation roll (7) rotated in a circumferential direction and are able to run along a rotational direction of the separation roll (7), an object (P) to be processed supplied between the filtration belt (1) and the seal belt (8) is sandwiched between the filtration belt (1) and the seal belt (8) on the outer circumference of the separation roll (7) and squeezed by the squeezing belt (15), and the object (P) to be processed is dehydrated by being ventilated by ejecting a ventilation gas toward a radially outer side of the separation roll (7) via a ventilation gas chamber (10) formed in an inner circumferential portion of the separation roll (7), in which the seal belt (8) is a woven fabric of multifilament or a woven fabric obtained by combination of multifilament and monofilament and is a thinner than the squeezing belt (15).

    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: 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.
