Abstract

The invention discloses an energy-saving heating device for coal slime water, which comprises an air compressor, a hot gas chamber, a heat exchanger, a water storage tank, a first water pump, a second water pump, a heating mixing pipe and a fan; the coal slime water discharged from a flotation machine Flow into the concentration pool through the heating mixing tube, the heating mixing tube is provided with a 180 ° twisted spiral blade, the outer diameter of the spiral blade is slightly smaller than the inner diameter of the heating mixing tube, and the spiral blade is a hollow structure; The pipe wall of the heating mixing pipe is a double-layer structure, which is divided into an inner pipe wall and an outer pipe wall. The hot water and hot air generated by the waste heat of the compressor heat the slime water, which avoids the waste of waste heat generated by the air compressor, increases the temperature of the slime water when the external environment temperature is low, saves the amount of flocculant used, and reduces the Coal washing costs.

Description

technical field [0001] The invention relates to the technical field of coal washing, in particular to an energy-saving heating device for coal slime water. Background technique [0002] Dense medium-flotation combined process is a common coal preparation process in coal preparation plants, including two parts: dense medium coal preparation process and flotation coal preparation process. The water for coal washing is recycled, and the lost water is replenished to the concentration pool. The tailings water discharged from the flotation machine flows into the thickening tank. This part of the tailings water is also called slime water. Changes in the temperature of the slime water will have a certain impact on the flocculation effect. When the temperature of the slime water is higher, the slime flocculation effect is better and the sedimentation speed is faster; when the temperature is lower, the flocculation effect is relatively poor and the slime sedimentation speed is slower...
