PLANT FOR PURIFICATION OF CONTAMINATED LIQUID Russian patent published in 2000 - IPC

FIELD: liquid purification plants. SUBSTANCE: plant has vessel with contaminated liquid, filter unit, pressure pump with inlet and outlet pipes and vessel with purified liquid. Pump outlet pipe is connected with filter inner hollows by means of inlet main pipe. Pump inlet pipe is connected by means of one discharge main line with filter hollows for discharge of incompletely purified liquid. Filter hollows for discharge of purified liquid are connected by other discharge main line to vessel with purified liquid. Plant has a mixing chamber in the form of cylindrical pipeline whose outlet end is connected with pump inlet pipe via conical diffuser expanding towards pump inlet pipe. Pipeline inlet end is connected with inlet collector formed by conjugated cylindrical tubular section and conical tubular section coupled with inlet end of pipeline. Installed in conical tubular part of collector is nozzle in the form of truncated hollow cone. EFFECT: higher purification efficiency and reduced power consumption in purification process. 2 dwg
