Problems solved by technology

[0003] With the increase of the proportion of mechanized coal mining, the content of fine-grained coal mined is increasing, and the particle size is fine, the ash content is high, the viscosity is high, and it is difficult to settle, resulting in poor washing effect, and even the coal preparation system cannot operate normally. It affects the effect and efficiency of coal preparation, and coal preparation uses a lot of clean water, which also causes a lot

Abstract

The invention relates to a method for ultrasonic treatment, electrolysis and flocculation of slime water. The method is characterized in that an ultrasonic treatment, electrolysis and flocculation technology is utilized to treat slime water according to the actual situation of slime water treatment to obtain coal slime, the coal slime is dried to obtain an industrial raw material with high additional value, and the treated water is collected for use. The treatment method has the advantages of continuous process, high speed, high efficiency, high sedimentation rate (increased by 60% compared with the prior art) and low water turbidity (reduced by 60%), can be industrially applied in coal separation field, and is a very ideal treatment method of slime water; and the washed and separated coal product has good purity and fewer impurities, and can be used as a raw material in the pharmacy, fine chemistry industry and high-additional-value industries.

Description

technical field [0001] The invention relates to a method for ultrasonication, electrolysis and flocculation of coal slime water, which belongs to the technical field of coal washing, purification and water recovery. Background technique [0002] Coal is a mixture that contains a variety of chemical substances, such as carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. In high value-added industrial applications, coal is often required to be washed. The most commonly used washing method is to use Water is used as the medium for washing. First, coal and water are combined to form a mixture, and then the mixture is washed. [0003] With the increase of the proportion of mechanized coal mining, the mined fine-grained coal content is increasing, and the particle size is fine, the ash content is high, the viscosity is high, and it is difficult to settle, resulting in poor washing effect, and even the coal preparation system cannot operate normally. It affects the effect ...
