Single-motor circulating granulation fluidized bed coupled filtering solid-liquid separation equipment

Abstract

The invention provides single-motor circulating granulation fluidized bed coupled filtering solid-liquid separation equipment. Stirring blades are mounted on a stirring shaft in a granulation fluidization area in an inner cylinder; the bottom end of the stirring shaft penetrates through the water distribution device and the bottom of the water inlet pipe to be connected with the mud scraper; a suspension layer filtering solid-liquid separation device is arranged in the separation area; the suspension layer filtering solid-liquid separation device is divided into an upper part and a lower part,the upper part is a static suspension layer, the lower part is a stirring suspension layer, the static suspension layer is filled with floating light suspension beads, a filtering layer stirring blade is arranged in the stirring suspension layer, and the filtering layer stirring blade is arranged on a stirring shaft in a sleeve manner through a stirring shaft connecting sleeve; and a single stirring driving motor simultaneously drives the filter layer stirring blades, the stirring blades and the mud scraper to rotate together through the stirring shaft. The suspended layer filtering solid-liquid separation device can effectively intercept tiny particles which cannot be removed at the bottom of the fluidized bed, so that the water turbidity and suspended matters in the separation area areobviously reduced.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to a granulation fluidized bed, in particular to a single-motor circulating granulation fluidized bed coupled filtration solid-liquid separation equipment. Background technique [0002] With the development of the national economy, the task of water pollution control is getting heavier and heavier, the concentration of suspended solids in water is getting higher and higher, and the task of removing suspended solids in water treatment processes is getting heavier and heavier. Therefore, the development and research of efficient solid-liquid separation Devices are an inevitable development trend. A large number of water treatment technologies and equipment based on the theoretical basis of solid-liquid separation in the suspension layer have been developed and widely used in practical projects. Typical equipment includes French Veolia Actifl o clarifiers, French Degremont company DensaDeg ...
