Description

Technical Field

[0001] The utility model relates to the technical field of coal chemical processing, in particular to a sludge separation device for coal chemical wastewater treatment. Background Art

[0002] Coal chemical industry is a comprehensive industrial process that uses mined coal as raw material and converts it into various fuels and chemicals through a series of chemical processes. As one of the traditional industries, the high energy consumption, high emissions and low efficiency of coal chemical industry have always restricted the development of this industry. Although the introduction of new green coal chemical technology in recent years has improved the pollution situation, the serious pollution of the environment by the coal chemical industry still cannot be effectively solved. Among them, wastewater discharge has the most serious impact on the environment. These wastewaters mainly come from coking, gasification and liquefaction processes, and are characterized by poor biodegradability and complex composition, most of which are toxic and harmful substances.

[0003] A sludge separation device for coal chemical wastewater treatment is disclosed in the Chinese patent publication number CN207159079U. The patent technology can precipitate the sludge in the wastewater through the settling chamber, and discharge it through the seepage plate at the bottom, so as to separate the sludge from the water for the first time. The separated sludge falls into the filter plate in the filter chamber, and the sludge is separated from the wastewater again.

[0004] However, when the above patented technology is implemented, it mainly separates sludge and water through the seepage plate. However, the above method will cause the mesh diameter of the seepage plate to be too large, so that the sewage and the sludge will be discharged through the seepage plate together. If the mesh of the seepage plate is too small, it will be difficult for the sludge to come out of the seepage plate, which will reduce the efficiency of sludge separation. Therefore, there are certain shortcomings.

[0005] In summary, it is necessary to invent a sludge separation device for coal chemical wastewater treatment. Utility Model Content
