Abstract
PURPOSE: To prevnt the explosion of inflammable powder during its conveyance from a first storage vessel to a second one provided at the end of a conveyance pipe, by using an anti-explosion mechanism.
CONSTITUTION: Powdered coal is taken out from a first storage vessel 1 through a discharge valve 2 and drops into a conveyance pipe 3 so that the powdered coal is conveyed into a second storage vessel 5 by a rapid air flow from a blower 4. Some of the powdered coal, which accompanies the air flow, is caught by a dust collector 11. Even if the powdered coal explodes due to spontaneous igmition in the second storage vessel 5, a vent 6 is broken by the explosion pressure so that the pressure is released. The pressure in the storage vessel 5 is detected by a pressure sensor so that a controller 10 operates on the basis of the signal of the sensor to stop the operation of the discharge valve 2 and the blower 4.
