INVERSELY-OSMOTIC DISTILLING PLANT

摘要

FIELD: sea water distilling units; compact and small-sized marine distilling plants. ^ SUBSTANCE: proposed distilling plant includes high-pressure plunger pump, preliminary sea water cleaning filter, inversely-osmotic distilling module and shut-off and adjusting fittings; preliminary sea water cleaning filter consists of coarse filtering cartridge of large diameter with fine filtering cartridges of smaller diameter arranged inside it; filtering cartridge is mounted in cylindrical housing. Distilling plant includes additionally adjustable check valve for directing the flow to pump which is fitted in delivery pipe line of pump past its standard outlet valve; distilling plant is also provided with hydraulic accumulator connected to outlet pipe line of sea water preliminary cleaning filter through throttle valve and check valve mounted in parallel for directing the flow from hydraulic accumulator; plant is provided with adjustable check valve mounted in filter outlet pipe line for directing the flow from filter after point of connection of hydraulic accumulator. Delivery pipe line of pump is connected with cylindrical housing of filter in its upper part through inlet branch pipe which is tangential to housing; at the bottom, housing has external taper tray with pipe line; inner cavity of coarse filtering cartridge is communicated at the bottom with external taper tray provided with pipe line arranged inside external tray; coarse and fine filtering cartridges are made in form of rigid carcasses. ^ EFFECT: improved quality of preliminary cleaning of sea water due to effective three-stage filtration; increased service life of distilling module; reduction of vibration and noise level. ^ 2 dwg
