摘要： PURPOSE:To maintain solution supply in a fixed volume over long time, by adjusting the speed of a fixed volume pump, and as well by controlling the back pressure of the fixed volume pump so that the supply volume of solution from the fixed volume pump is always constant. CONSTITUTION:Solution in a pressurized solution tank 26 is pressurized by a fixed volume pump 11 and is fed through a solution supply conduit 13 to, for example, a thin membrane type centrifugal dryer 12. Futher, the supply volume of solution is controlled to be always constant by adjusting the speed of the fixed volume pump 11 with the use of a flow detector 18, a flow control unit 19 and a speed governor such as, for example, a speed change unit 21. A pressure control unit 30 arithmetically compares the internal pressure of the pressurized solution tank 26 which is detected by a pressure detector 29, with the back pressure of the fixed volume pump which has a corelation with the supply volume of solution from the fixed volume pump 11, that is set beforehand on the flow control unit 19. With the result of the comparison, the valve opening degree of a pressure regulating valve 27 is adjusted for feeding pressurized gas so that the supply volume of solution from the fixed volume pump 11 is controlled to be constant.

摘要： PURPOSE:To decrease the compression stress of heating pipe drum and tensile stress of heat transmission pipe and to prevent these thermal breakage, by enclosing cooling liquid in the drum of outside of the heat transmission pipe while the temperature of waste liquid is low, at the time of starting the operation. CONSTITUTION:Cooling water is sent in the drum 38 of the heating pipe 14 and after that, waste liquid from the waste liquid tank 18, is introduced before the waste liquid concentrating operation and is supplied to the level H in the evaporation pipe 16 through the heat transmission pipe 44. Temperature of the waste liquid collected in the pipe 16, is detected by the detector 68 and outflow pressure is set by the control valve 64 in accordance with said temperature. Next, superheated steam is introduced from the inlet pipe 40 and the cooling water in the drum 38 is pushed out to the set pressure of the valve 64. The waste liquid is heated by the heat exchange with the superheated steam while passing through the pipe 44 by circulating in such condition and the cooling water is discharged through the valve 64 corresponding to it. Regular operation without using the cooling water, is performed when the waste liquid is reached the operation temperature.

摘要： PURPOSE: To prevent the decrease in adsorption performance by flocculating and separating moisture from the regenerated gas from an adsorber, bringing the regenerated gas into contact with an aq. alkaline soln. and separating carbon dioxide as carbonate therefrom then supplying the gas again to the adsorber.
CONSTITUTION: A regenerated gas contg. carbon dioxide alone is supplied through a conduit 23 to the lower part of a gas adsorption column 17 and while the gas ascends in the column 17, the gas contacts in counter current with the aq. alkali soln. which is supplied through a conduit 27 to the top part of the column 17 and flows down. The carbon dioxide contained in the regenerated gas is converted to carbonate, for example, sodium carbonate which is held dissolving in the water and is discharged from the bottom of the column 17 through a conduit 28. On the other hand, the regenerated gas separated of carbon dioxide entrains the mist contg. sodium hydroxide therein and is supplied from the upper part of the column 17 through a conduit 29 to a mesh filter 11b, where the entrained mist is captured.

摘要： PURPOSE:To remove radioactive solns. stuck and grown in the slurry area of heat ransfer surfaces without stopping the operation of an evaporator by making the temp. of a heat medium slightly lower or higher than the temp. of the heat medium in the stage of steady operation then returning the temp. to the temp. in the steady operation. CONSTITUTION:In the stage of evaporating sodium sulfate with a centrifugal thin film evaporator, a concentrating area Ha is expanded up to a slurry area Hb in the stage of steady operation by making the temp. of a heat medium lower than the temp. of the heat medium in the stage of steady operation to transfer the slurry area to the powdering area Hc in the stage of steady operation. Further, for the sodium sulfate stuck in the area Hc, the area Hc is reset to the powdering area by returning the temp. of the heat medium to the temp. of the heat medium in the stage of steady operation after the sodium sulfate in the area Hb is removed, then the sodium sulfate is scraped off by the scraping force of rotary vanes 15 and is powdered. Such operations are repeated in accordance with the degrees of sticking and growing of the sodium sulfate in the area Hb.
