Vertical eddy current reinforced separation device and granulation fluidized bed for efficient solid-liquid separation

Abstract

The invention provides a vertical eddy current reinforced separation device and a granulation fluidized bed for efficient solid-liquid separation. The vertical eddy current reinforced separation device is arranged in a separation area; and the vertical eddy current reinforced separation device comprises a stirring shaft sleeve arranged at the center, wherein multiple corrugated pipes vertically fixed together are arranged at the periphery of the stirring shaft sleeve, the two ends of each corrugated pipe are clamped between a pair of crisscross frames, the centers of the crisscross frames are arranged at the two ends of the stirring shaft sleeve, the end parts of the crisscross frames are fixed on the inner wall of a tank body in the separation area. The vertical eddy current reinforced separation device can produce vertical eddy current, and the vertical eddy current has secondary growth promoting effect on small particles entering the device, so that yield of large particles is improved, and separation efficiency is improved. The granulation fluidized bed provided by the invention also can improve the yield of the large particles and the separation efficiency due to adoption of the vertical eddy current reinforced separation device.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to a granulation fluidized bed, in particular to a vertical vortex enhanced separation device and a granulation fluidized bed for efficient solid-liquid separation. Background technique [0002] As the country pays more attention to environmental protection and the shortage of water resources, water purification and waste water recycling are getting more and more attention. 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 Actiflo clarifier, French Degremont company DensaDeg high-density clarifier and Philip et al. The developed high-efficiency carrier flocculation device, etc. The above-mentioned equipment has successfully realized the integration and equipment of water treatment technology, and ...
