Abstract

The self exciting oscillation pipeline type flocculator is for water supply, industrial waste water and domestic sewage treating engineering and possesses flocculation, deposition, floating and other functions. The flocculator includes water nozzle, mixing cavity, upper nozzle, self exciting cavity and lower nozzle connected successively through pipeline; as well as chemical adding tank, flow rate regulating valve and flocculant conveying pipe with outlet to the mixing cavity connected together. The present invention has raised colloid particle bridging and adsorbing effect and thus raised flocculating efficiency. The flocculator has the pulse flow with pressure amplitude 15-30 ΓΊΓ‘ higher than that of inflow.

Description

Technical field:

[0001] The invention relates to a pipeline type flocculator for water treatment, which is used in operations such as flocculation, sedimentation and flotation in the treatment engineering of water supply, industrial waste water or urban domestic sewage. Background technique:

[0002] Flocculation plays an important role in water supply and wastewater treatment and has been widely used. It is the basis of sedimentation, flotation and other treatments. The traditional flocculation method usually requires a mechanical stirring device to mix the flocculant evenly in the adjustment tank, and the required flocculation time is as long as 20-30min, or even longer, with high energy consumption and low utilization efficiency. Therefore, the study of high-speed and high-efficiency in the flocculation stage has always been a subject of concern. On the other hand, the unitization, pipelineization and serialization of environmental protection equipment have become the cu...
