Description

Technical Field

[0001] The utility model relates to the field of filter pressing and dehydration, in particular to a high-pressure vertical filter pressing and dehydration system. Background Art

[0002] The treatment of solid waste follows the principles of resource utilization, reduction, and harmlessness. Reducing the moisture content of solids not only reduces transportation and disposal costs, but also provides better conditions for subsequent treatment such as composting and incineration. Sludge is usually pretreated to improve dewatering properties before dewatering. Dewatering methods are divided into natural drying and mechanical dewatering. Natural drying is limited by usage conditions and has fewer applications. Mechanical dewatering methods include filtration and centrifugation. Filtration involves filtering wet sludge through a filter layer, allowing water to penetrate the filter layer and the dewatered sludge to be retained on the filter layer. Centrifugation separates mud and water by utilizing the different centrifugal tendencies generated by the difference in specific gravity between solids and liquids in the sludge.

[0003] However, most of the existing filter press dehydration equipment has a complex structure and a low degree of automation, and is gradually unable to meet people's growing production needs. Utility Model Content
