Scheme one, the leaf prefilter of spiral and reverse osmosis membrane filt are set
Arrange the leaf prefilter of spiral, blades axes is provided with five groups of blades, five groups of blades are axially evenly arranged along blades axes, and rear one group of blade is relative to last group of blade, and circumferential deflection 72 degree, forms spiral-line and arrange; On this basis, the water through the leaf prefilter process of spiral is directly introduced reverse osmosis membrane filt.
Scheme two, ultrasonic cleaner, force (forcing) pump, water storage box and sterilizer are set
Ultrasonic cleaner is set near reverse osmosis membrane filt, force (forcing) pump is set after reverse osmosis membrane filt, after force (forcing) pump, water storage box is set, after water storage box, sterilizer is set, the fresh water of the installation below delivery trunk of sterilizer.
Scheme three, seabed fixed leg is set
Below device base plate, place four seabed fixed legs, whole device to be fixed under sea 30 meters of dark seabeds by seabed fixed leg.
Scheme four, working process
Under the pressure of seawater, seawater enters the leaf prefilter of spiral, the seawater pretreated through strainer enters reverse osmosis membrane filt, after reverse osmosis filter, the fresh water of output is introduced force (forcing) pump and again enter water storage box by force (forcing) pump pressurization, water storage box exports water and enters sterilizer, and sterilizer exports fresh water by fresh water output tube, and ultrasonic cleaner removes the marine alga dirt above pretreated filter disc and reverse osmosis membrane by ultrasonic wave.
Core content of the present invention:
A kind of screw type sea water desalinator, arranges after the leaf prefilter of spiral, reverse osmosis membrane filt, force (forcing) pump, water storage box and arranges sterilizer.
Arrange the leaf prefilter of spiral, blades axes is provided with five groups of blades, five groups of blades are axially evenly arranged along blades axes, and rear one group of blade is relative to last group of blade, and circumferential deflection 72 degree, forms spiral-line and arrange; On this basis, water through the leaf prefilter process of spiral is directly introduced reverse osmosis membrane filt, ultrasonic cleaner is set near reverse osmosis membrane filt, after reverse osmosis membrane filt, force (forcing) pump is set, after force (forcing) pump, water storage box is set, after water storage box, sterilizer is set, the fresh water of the installation below delivery trunk of sterilizer.
