In general, in thermal power plants, wastes such as coal dust (or coal dust) generated while transporting upper and lower coal to the coal silo, coal water generated after water cleaning in the coal pit, coal water, and wastewater sludge generated from desulfurization facilities of thermal power plants are generated. do. Coal, coal water slurry, wastewater sludge, and wood pellet dregs produced in thermal power plants are referred to as wastes produced in thermal power plants. The mixture of this waste is referred to as the coal brine sludge of the present invention, and the coal brine sludge of the present invention is applied to the application No. It means lowering the primary moisture content described in). Therefore, the apparatus for reducing the moisture content of the coal sludge of the present invention (hereinafter referred to as the moisture content reduction device) is a device for lowering the secondary moisture content of the coal sludge. However, the apparatus for reducing the moisture content of the present invention may not necessarily be used at the time of reducing the secondary moisture content, and may also be utilized as a primary moisture content reducing device depending on the installation environment. In addition, the coal water solution of the present invention may be a mixture without any one of the wastes described above, or may be composed of water and powdered coal.

7. The method of claim 6,
The filter cloth and the outer cylinder part are each configured in a semicircular shape,
The apparatus for reducing moisture content of coal water sludge, characterized in that it further comprises a coupling clamp portion provided in the circumferential direction of the outer cylinder portion to combine the first and second semicircular shapes.
9. The method of claim 8,
It is disposed on the central axis of the rotating part, by being coupled to the coupling clamp unit, a plurality of sludge cylinder parts to be fixedly arranged on the central axis, the coupling plate further comprising a water content reduction device of the sludge.
10. The method of claim 9,
The bonding plate is
A device for reducing moisture content of coal water sludge, characterized in that the number of coupling plates equal to the number of the plurality of sludge cylinders is formed to protrude from the body of the coupling plate.
The method of claim 1,
A proximity sensor unit for detecting whether the rotating unit is rotated normally at a predetermined angle;
A ball sensor unit for detecting the normal rotation of the rotating part by the movement of the ball by having an air cylinder part for spraying air, a ball part disposed on the rotating part and the ball moving in one direction by the injection of the air;
A load cell unit for sensing the weight of the inlet cylinder receiving the homogenized coal water sludge;
When a timer is provided, the apparatus for reducing moisture content of coal water sludge, characterized in that it further comprises a rotation control unit for controlling the load cell unit, the proximity sensor unit and the ball sensor unit.
Coal water sludge is homogenized by the homogenizer;
A step in which the homogenized coal water sludge is introduced into the inlet cylinder part,
When the weight is sensed by the load cell unit or a predetermined time elapses by the timer unit as the coal water sludge flows into the inflow cylinder unit, the rotation control unit rotates the rotating unit at a predetermined angle step by step;
Detecting normal rotation by the proximity sensor unit or the ball sensor unit;
When a normal rotation is detected, the dewatering hydraulic cylinder unit moves to the dewatering cylinder side by the rotation control unit and compresses, dewatering the homogenized coal water sludge to make coal;
Discharging the bullet to the outside by moving the discharge hydraulic cylinder unit toward the bullet discharge cylinder unit by the rotation control unit when the normal rotation is detected;
and returning to the original position by controlling the dewatering hydraulic cylinder unit and the discharging hydraulic cylinder unit by the rotation control unit when the dewatering and discharging are completed.
