Background
The coal slime water is mainly characterized in that a flocculating agent is added to promote particles in the coal slime water to carry out flocculation and precipitation, then the lower layer of the coal slime water is concentrated in a thickener, and the purpose of clarification is achieved through reduction of the content of particulate matters in the coal slime water at the upper layer.
As shown in figure 1, the concentration tank is provided with 4 subareas, a clarification area A, a take-off and landing area B, a transition area C and a compression area D, and after a flocculating agent is added into the concentration tank, the agent enters a discharge port below the central part of the concentration tank along with coal slime water to slowly flow to the periphery in a uniform radiation state. In the process of flowing the coal slime water from the center to the periphery, the concentration of the coal slime water is low at the beginning, and solid particles freely lift from top to bottom. After the flocculant is added, the particles flocculate, and the settling speed of the particles falling into the transition zone is accelerated. The particles in the transition zone further sink to form a compression zone with higher concentration, and water is continuously separated out in gaps of the settled particles and then continuously pushed into a central discharge port by the rake frame. And guiding the discharge amount of the bottom mud and the dosage through sediment concentration detection data, promoting the water separation effect to be strengthened, and keeping a clear water zone on the upper part of the pool to overflow continuously.
The flocculating agent can be increased or decreased according to the flocculation condition by observing the clarification area of the concentration tank, and the addition error is larger due to the fact that the existing method of direct observation through naked eyes cannot carry out sealed example observation on the middle lower part of the clarification area, excessive waste materials are added, the cost is increased, too little sedimentation effect is not added, and the normal supply of the circulating water is influenced.
Accordingly, further developments and improvements are still needed in the art.
