Abstract
The invention discloses a long-distance pipeline coal conveying terminal dehydration system device and dehydration method. The device comprises a pulp storage tank, a settling filtration type centrifuge, a thickener, a pressure filter, a sewage treatment plant and a coal storage yard. Coal pulp in the pulp storage tank is conveyed to the settling filtration type centrifuge through a slurry pump to perform dehydration, and filtrate of the settling filtration type centrifuge enters a settlement centrifugate barrel and then is conveyed to the thickener through a pump to perform thickening; bottom flow of the thickener is conveyed to an agitating vessel through the pump; the ore pulp in the agitating vessel is agitated and then conveyed to the pressure filter through the pump to perform dehydration; the overflow of the thickener and the filtrate of the pressure filter enter another thickener for thickening; and the thickened bottom flow is conveyed to the agitating vessel through the pump. A product dehydrated by the settling filtration type centrifuge and a product dehydrated by the pressure filter can be directly transported and sold. The long-distance pipeline coal conveying terminal dehydration system device is simple in structure, convenient to mount and use, good in dehydration effect, and low in product water ratio, and the settling centrifuge centrifugate and the filtrate of the pressure filter are subjected to deep thickening, so that the thickening overflow concentration is low, the industrial emission standard is met, and the long-distance pipeline coal conveying terminal dehydration system device is widely used in the industry of dehydration of pulp materials.
