Abstract:
A method for efficiently conveying impurities in a pressurized fluidized incinerator system is provided. Cleaning gas is supplied to an upper valve, and thereafter, the upper valve is driven so as to communicate an upper discharge device and a tank. The upper discharge device is driven so as to convey the impurities from the dust collector to the tank, and thereafter, the upper discharge device is stopped and the upper valve is driven so as not to communicate the upper discharge device and the tank. Thereafter, the supply of the cleaning gas to the upper valve is stopped.

Abstract:
An air diffuser includes: a bottom panel provided in a horizontal direction in a tank in which water is filled; an air diffusion body installed to cover the bottom panel from above; and air diffusion holes arranged to penetrate through the air diffusion body, gas fed to a gap between the bottom panel and the air diffusion body is discharged into water through the air diffusion holes, and an air diffusion region of the air diffusion body where the air diffusion holes are arranged has a width equal to or larger than 10 mm and smaller than 120 mm. A method of treating water using the air diffuser includes supplying air to the air diffuser at a volume of equal to or smaller than 60 [Nm3/(m2·hr)].
Abstract:
A bioclean room 21 is formed by an inside space surrounded by a frame body 1 on a floor with side portions of the frame opened and curtains 20 provided to be selectively opened and shut to cover the opened side portions of the frame body 1. In the frame body 1, provided is an air flow passage which is equipped with an air cleaning device therein and runs upward from the foot side of the patient so as to deliver the air in the frame body and along a top plate 6 to an air blow duct 19 above the patient's head through which clean air is blown into the bioclean room 21. Inside the air flow passage, provided is an air cleaning device. The frame body is equipped with an opening 9 on the head side of the patient through which a medical console 25 on a wall 26 of a sickroom can be received to be positioned inside the bioclean room 21 when the frame body 1 is brought into abutment against the wall 26.
Abstract:
An operation management support system for a water treatment plant includes an air supply pipe, an air diffuser, a treatment water tank, a vibration information collection device, and an information processing device. The information processing device includes a vibration information obtainment unit which obtains the vibration information from the vibration information collection device and performs predetermined transform processing for the obtained vibration information, a determination algorithm execution unit which executes processing based on a predetermined determination algorithm for the vibration information for which the predetermined transform processing is performed by the vibration information obtainment unit, a vibration information determination unit which makes a determination about an abnormality of the air diffuser based on an output result output from the determination algorithm execution unit, and a determination result notification unit which notifies a result of a determination by the vibration information determination unit.
Abstract:
A drive device for a belt conveyor device includes a drive pulley, a first pulley, a second pulley, a support frame, and a drive motor. The drive pulley has a drive shaft direction length less than a plurality of previously set belt widths of the endless belt and has the driving shaft direction length being set to a same length regardless of the plurality of previously set belt widths of the endless belt. Axial lengths of the first pulley and the second pulley are set to the same length as the axial lengths of the head pulley and the tail pulley. The support frame is rotatably attached to the first pulley and the second pulley. The drive motor hung from a lower surface of the support frame in order for the drive pulley to be positioned at an approximately center portion in a width direction of the endless belt.
Abstract:
A pressurized incineration facility (100, 200) includes: a pressurized incinerator (1) which incinerates a processing object (P) under a pressure increased by compressed air (A); a turbocharger (5) which produces the compressed air by being rotationally driven by combustion exhaust gas (G) of the pressurized incinerator; and a seal device (5i) which jets seal gas (S) to a rear surface (5a1) of a turbine impeller (5a) of the turbocharger.
Abstract:
Is provided a method for starting up a pressurized fluidized bed incinerator system by which cracking of silica sand as a bed material can be prevented at low costs. By heating the silica sand as the bed material filled up in a bottom portion of a pressurized fluidized bed incinerator, a temperature of a freeboard of the incinerator is heated, and after the temperature of the freeboard is heated to 750 to 900° C., a material to be treated having a water-containing organic substance is fed to the pressurized fluidized bed incinerator.
