Title: Radiactive concentration monitor
Inventor: KURIHARA JIRO
IPC: G01T1/00
Filed: 1990-06-28
Abstract: PURPOSE:To make a trace monitoring of a high concentration solution possible by controlling a driver doing actions of a concentration distribution monitoring, etc., being able to move neutron detectors arranged to both symmetrical sides of a washing column from the bottom to the top by the driver. CONSTITUTION:A control unit 6 outputs command signals to a driving unit 9 to make neutron detectors 2 and 3 move when the measured level from a measuring unit 5 becomes below an alarm set level after outputting abnormal signals in the monitoring mode after abnormal occurrence. The unit 9 selects either of the two detectors, 2 and 3, to move alternately, drives a wire rod driver 10, moves the selecting detector to an abnormally high concentration occurrence position and execute trace monitoring, moving it to follow up the rise of the high concentration solution. Thus, it can be confirmed that the high concentration detecting is not due to a malfunction of the device, and for moving of the detector the other neutron detector stops at the lower part of the washing column and keeps monitoring, an inflow of an abnormal concentration solution can be immediately detected if it occurs.

Abstract: PROBLEM TO BE SOLVED: To implement sufficient atomization and to make fuel be a wide-angle solid spray, by comprising swirl mechanism for forming a swirl flow of fuel around a valve seat and a valve element, and an auxiliary fuel supply means for supplying the fuel to a center portion of the fuel spray injected from a fuel injection port. SOLUTION: A fuel swirl element (a swirler) 2 comprises; four eccentric base swirl grooves 10 on bottom faces of the swirler 2; for eccentric upstream swirl grooves 11 above the bottom faces of the swirler 2; and a fuel swirl chamber 12 for bypassing the base swirl grooves 10 and upstream swirl grooves 11. When a valve element lifts according to a injection signal, fuel is made to flow into the swirl grooves 10, 11 through a fuel passage 14 disposed between the swirler 2 and an injector body. The fuel in the fuel swirl chamber 12 is started to swirl caused by a flow of the upstream swirl grooves 11. Since swirl flows of the fuel formed in the base swirl groove 10 are not weaken to be injected, a current in a swirl direction and a current in a perpendicular direction become almost the same velocity, as time passes off.  Accordingly, an injection angle in a first stage is made to be narrower and an injection angle in a last stage is made to be wider so that flow rate distribution is provided near a center of spray, resulting in uniform fuel distribution in the spray.
