<P>PROBLEM TO BE SOLVED: To provide a rotary and pressurizing dehydrator capable of treating objects to be treated such as sludge at a higher dehydrating degree as compared with conventional ways. <P>SOLUTION: In the rotary and pressurizing dehydrator 1 in which the liquid objects to be treated are introduced into an annual filter chamber 11 formed between an inner wheel spacer 3 and a deflector 6, and an outer wheel spacer 4 to make the objects to treated proceed to a front side by rotating a screen 5, and to turn them gradually dehydrated by gradually pressurizing, the inner diameter R of the outer wheel spacer 4 is set in a range of 800-1,000 mm and then the ratio of the outer diameter r of the inner wheel spacer 3 to the inner diameter R of the outer wheel spacer 4 is set in a range of 0.36-0.46. <P>COPYRIGHT: (C)2008,JPO&INPIT |
