NOVELTY - Sludge heat drying and coal co-combustion treatment system comprises a sludge tank, a sludge spiral conveyor, a screw pump, a dryer, a cyclone separator, a dry sludge spiral conveyor and a belt conveyor. The sludge tank is for storing sludge. The sludge tank is provided with a movable cover plate. The bottom of the movable cover plate is provided with a hydraulic drive. The sludge spiral conveyor is set in the sludge storage tank outlet of the sludge to the sludge spiral conveyor under the action of hydraulic driving. The screw pump is connected with the first spiral conveyor.    USE - Used as a sludge heat drying and coal co-combustion treatment system.    DETAILED DESCRIPTION - Sludge heat drying and coal co-combustion treatment system comprises a sludge tank, a sludge spiral conveyor, a screw pump, a dryer, a cyclone separator, a dry sludge spiral conveyor and a belt conveyor. The sludge tank is for storing sludge. The sludge tank is provided with a movable cover plate. The bottom of the movable cover plate is provided with a hydraulic drive. The sludge spiral conveyor is set in the sludge storage tank outlet of the sludge to the sludge spiral conveyor under the action of hydraulic driving. The screw pump is connected with the first spiral conveyor. The first spiral conveyor is connected with the dryer. The sludge spiral conveyor conveys sludge to the screw pump. The sludge is sent to the dryer. The dryer with the power station boiler in the high temperature flue gas is sent to the sludge in the process of drying. The cyclone separator is set at the outlet of the dryer. The dried sludge and the flue gas contain water vapor. The dry sludge spiral conveyor is connected between the cyclone separator and the belt conveyor. The belt conveyor will transport the dried sludge to a coal conveyor belt and power station coal-fired mixed together into the boiler combustion.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the sludge heat drying and coal co-combustion treatment system (Drawing includes non-English language text).
