摘要： PROBLEM TO BE SOLVED: To uniformly control the temperature in a clean room at low costs by installing a supply port for supplying air being subjected to air-conditioning according to preset conditions in a return channel. SOLUTION: Since an air-supply vent 9 is provided at the lower part of a return channel 12, the mixing of warm return air 11 and cold supply air 10 is nearly completed while air is flowing in the return channel 12. When the mixture flows into a ceiling room 2, the temperature of the airflow is made nearly uniform and is nearly set to a setting value, thus preventing the nonuniformity of temperature from being generated in the ceiling room 2, sucking air with the same temperature by all fan filter units 4 for discharging into a clean room 1, and also making uniform the temperature in the clean room 1. In this manner, the temperature becomes uniform at a point of time when the return air flows into the ceiling room 2, generating the effect in either of small-, middle-, and large-scale clean rooms. Furthermore, the need for forming an eddy is eliminated, thus reducing the height of the ceiling room 2 and the height of the whole of the clean room for reducing costs.

摘要： PURPOSE:To prevent othe expansion of contamination by the waste material by providing an inclusion, which moves simultaneously with the wastae material and prevents the waste material and a conveying device from contacting each other directly, between the bottom surface of the waste material and the conveying device where it is mounted for each waste material. CONSTITUTION:Waste material 3 on a palette 1 installed on a palette cradle 2 are clamped and moved, one by one, by a depalletizer 4 and carried to a specific start position of a drum conveyor 5. At this time, a drum can receiving pan 8 as the inclusion is installed at a specific position on the drum conveyor 5 previously and the waste material 3 are put on the drum can receiving pan 8 and moved. The drum can receiving pan 8 is a pan type and its internal diameter is made a little bit larger than the external diameter of a 200l drum can as the waste material 3, which has its bottom part stored in the drum can receiving pan 8. Consequently, the surface contamination of the waste mate rial 3 is prevented from extending to the conveying device 5 and an inspecting device 6.

摘要： PURPOSE:To impart a constant configurational dimension and strength, by controlling the amount of a powder pushed in between pistons by automatically adjusting the rotation of a powder mixing and push-in blade so that the configurational dimension of a detected pellet coincides with an objective value. CONSTITUTION:At the time of the finish of compression molding, the relation between two pistons 49, 50 detected by position detectors 55, 56, that is, the thickness of a formed pellet is inputted to an operational controller 53. On the basis of this information, the number of rotations of an electromotor 44 are changed by the operational controller 53 to adjust the feed amount of a powder to a powder receiving part 46 by a powder mixing and push-in blade 45. Concretely, when the thickness of the formed pellet detected as the gap between the pistons 49, 50 by the position detectors 55, 56 at the time of the finish of compression is larger than an objective value, the number of rotations of the electromotor 44 are lowered to reduce the amount of the powder fed to the powder receiving part 46 by the powder mixing and push-in blade 45.

摘要： PURPOSE:To control the production of sulfur oxide in an exhaust gas system to incinerate spent ion exchange resin with the use of an incinerator by pretreating positive ion exchange resin of the spent ion exchange resin into a substance in which the sulfur oxide does not produce. CONSTITUTION:Spent ion exchange resin put out from a condensate demineralizing tower is housed in a spent resin receiving tank 1. After a water content of the spent ion exchange resin housed in the tank 1 is lowered down to 5% of a degree of slurry concentration, the resin is fed to a centrifugal extractor 3 with the use of an extractor feed pump 2 and after it is treated down to about 50% of a water content, it is sent to a mixer 5 through a moisture meter 4. Here, a quantity of cation resin is calculated on the basis of the measured value of the moisture meter 4, and, for instance, sodium hydroxide 25% solution in alkali metal or alkaline earth metal is added from an addition tank 6 with the use of an addition pump 7 to uniformly mix with the use of a mixer 5 so that a sulfur content may becomes sulfate. The resin is sent to an incinerator resin hopper 8 to mix to incinerate together with other combustible micellaneous solid.

摘要： PURPOSE:To secure predetermined roll torque without lowering the set value of roll torque, in the control of a granulator for a radioactive waste powder, by lowering the number of rotations of a roll to a proper degree when said number of rotations approached that of a screw generating a slip phenomenon. CONSTITUTION:A powder 5 is received by a granulator hopper 1 and the screw feeder 2 in the hopper 1 is rotated by a driver 8 while the powder 5 is supplied between rolls 4 rotating at constant torque to molded into a plate shaped connected pellet 6 which is, in turn, guided to a pelletizer 15 to be separated into individual pellets 16. The rolls 4 are driven by a driver 7 and the torque of the rolls 4 is detected by a roll torque detector 9 through the detection of the power consumption of the roll driver 7 and the detection signal thereof is sent to an operator 13. The operator 13 combines the signals from a roll torque setting device 10 and a roll number-of-rotation setting device 14.
