Title: Method for detecting moisture of particulate material in fluidized chamber in fluidized bed treatment apparatus
Inventor: SHIBATA TAKEO
IPC: B01J2/16
Filed: 1985-09-02
Abstract: PURPOSE:To make it possible to continuously detect the moisture of the particulate material in a fluidized chamber in a non-contact state, by mounting a detection cylinder on the peripheral wall part of the fluidized chamber at the appropriate position thereof and feeding purge air in the detection cylinder. CONSTITUTION:A detection cylinder 5 having an infrared absorption type moisture meter 6 mounted to one end thereof is mounted to the proper area of the peripheral wall part of a fluidized chamber 2. An air feed pipe 7 is connected to the upper part of the detection cylinder 5 to feed purge air in the detection cylinder 5. This purge air generates an air stream directing to the fluidized chamber 2 within the detection cylinder 5 and the particulate material in the fluidized chamber 2 is prevented from entering the detection cylinder 5. Further, air jet nozzles 8, 9 are provided at the intermediate position of the detection cylinder 5 and at the position close to the opening end in the side of the fluidized chamber thereof along the bottom surface of the detection cylinder 5 and, if necessary, air injected from said nozzles 8, 9 to shake off the particulate material apt to adhere to the bottom surface of the detection cylinder 5. Because the particulate material flows down like a waterfall along the opening end surface of the detection cylinder 5, said particulate material holds a constant state with respect to the moisture meter 6 from the aspect of appearance.
