DEVICE FOR INTRODUCTION OF CHEMICAL REAGENT INTO FLOW IN PIPELINE Russian patent published in 2011 - IPC F17D3/12 

FIELD: machine building.

SUBSTANCE: device for introduction of chemical reagent into flow in pipeline consists of reservoir 1 for chemical reagent, of flush pump, of auxiliary pipeline for flushing chemical reagent through probe with outlet orifices from reservoir to flow in pipeline by means of pump. The probe corresponds to a rotating drum with an axle positioned in plane perpendicular to axis of the pipeline with offset from centre for not less, than 90 % of half of pipeline diametre, but not more, than half of sum of pipeline and drum diametres. The auxiliary pipeline is equipped with a calibrated connecting pipe. Propellers are made on external surface of the drum.

EFFECT: raised efficiency of mixing chemical reagent in flow of pipeline before pumping mixed product into well; increased accuracy of metering chemical reagent introduced into flow in pipeline.
