  • Publication number: 20240151090
    Abstract: A diagnosing device identifies a plugging operation period in which a plug door performs a plugging operation, the plug door having a guide roller attached thereto, the plug door being configured to perform an opening-closing operation and the plugging operation by allowing the guide roller to move along a guide rail; obtains drive information including a value representing at least one of a current value or a torque value of a drive unit, the drive unit being configured to drive the plug door; and diagnoses an abnormality in the guide roller or the guide rail based on the drive information observed during the identified plugging operation period.

  • Publication number: 20020195032
    Abstract: A super-high temperature molecular thermal decomposition device comprises a high temperature thermal decomposition device, a smoke decomposition device, and an automatic control device; an exhausting tube installed between the high temperature thermal decomposition device and the smoke decomposition device. The high temperature thermal decomposition device includes a combustion chamber. The combustion chamber has a cover, two electrode plates, and two electrode rods. The bottom of the combustion chamber is paved with a plurality of ball shape light illuminator Therefore, the transient temperature of the light illuminator is above 3000 degree C. Therefore, the waste in the decomposition device are decomposed and gasified transiently. The gas from the exhausting tube will pass through the combustion chambers one by one. The working principle of each combustion chamber is identical to that of the combustion chamber.
