FIELD: machine building. ^ SUBSTANCE: restoration method of permeability of pores of semi-permeable walls of graphite tubes of hyperfiltration installations, which implements the ability of restraining the leakage by fixed boundary layer of viscous non-compressed liquid on semi-permeable walls of porous channels of graphite tubes. At that, leakage occurs at excess pressure equal to 2.5 MPa. At that, at action of pulsating pressure created with ultrasonic converter operating in pulse mode rated at 4 kW, the required excess pressure value is reduced by 5 times to 0.5 MPa. ^ EFFECT: shortening the regeneration time of semi-permeable filter; reducing excess pressure value required for regeneration of semi-permeable filter by means of ultrasound. ^ 2 cl, 3 dwg |
