Inclined tube sedimentation device
Inclined tube precipitator refers to the sedimentation equipment with inclined tubes in the sedimentation area. In the sedimentation area of the horizontal or vertical sedimentation tank, inclined parallel pipes or parallel pipes (sometimes honeycomb packing can be used) are used to divide into a series of shallow sedimentation layers, and the treated and settled sediments move and separate from each other in each shallow sedimentation layer. According to their mutual movement direction, they can be divided into three different separation modes: reverse (opposite) flow, co-current flow and lateral flow. Every two parallel inclined plates (or parallel pipes) is equivalent to a very shallow sedimentation tank.
■ Working principle:

The inclined tube precipitator is manufactured according to the principle of separating fractional particles from sedimentation tank in advection mode. By adding inclined tubes in the tank, the hydraulic radius is reduced, and the wet cycle of the water cross section in the tank is increased. At the same horizontal flow velocity v, Reynolds number Re can be greatly reduced, thus reducing water turbulence and promoting precipitation. In addition, a 60-degree inclined tube assembly is installed above the sludge suspension layer, so that the suspended solids and solidified substances in the raw water or floc alum flowers are formed after adding coagulation, and accumulate on the bottom surface of the inclined tube to form a thin mud layer, which slides back to the sludge suspension layer by gravity, then sinks into the sludge collecting hopper, and is discharged into the sludge tank by the sludge discharge pipe for further treatment or comprehensive utilization. The supernatant gradually rises to the water collecting pipe for discharge, which can be directly discharged or reused.
■ Analysis of Process Advantages:
The laminar flow principle is used to improve the treatment capacity of the sedimentation tank |
The settling distance of particles is shortened, thus shortening the settling time |
The sedimentation area of the sedimentation tank is increased, thereby improving the treatment efficiency |
High removal rate, short residence time and small occupied area |
