Description

Technical Field

[0001] The utility model relates to the technical field of coal washing and sewage treatment, and specifically discloses a coal slime water treatment device. Background Art

[0002] Coal is the main energy source in China, accounting for 76% in the primary energy consumption structure. Coal is also a non-clean energy source and needs to be sorted and processed to reduce the content of minerals and harmful impurities as much as possible. At present, most coal sorting adopts wet coal washing, that is, water or a mixture of water is used as the sorting medium. It is estimated that the annual water consumption for coal washing in the country is about 6.2 billion m³ at present. The coal slime water after coal washing is a suspension containing a large amount of fine coal powder particles and other impurities. If directly discharged, it will cause great harm to water areas. In addition, the residual chemical agents in the coal washing operation and various metal ions associated with coal discharged with water will also seriously pollute the surrounding environment. Therefore, it is necessary to treat the coal slime water to separate the fine coal powder particles and other impurities in the coal slime water, so that the effluent meets the discharge standards.

[0003] The existing coal slime water treatment devices for coal washing and processing generally adopt the method of adding flocculants and acid-base treatment agents to the coal slime water, so that the milled coal powder particles in the coal slime water flocculate into large particles and settle. The settled pollutants are filtered through a filter screen. However, the filter screen of such devices is inconvenient to clean, and the pollutants are easy to block the filter screen, affecting the filtering effect. Therefore, a coal slime water treatment device is needed to solve this problem. Summary of the Utility Model
