The concrete use procedure of sea water desalting plant of the present invention is as follows:
First, rope 1 is fixed on to the upper end of column cylinder body 2 and pressure regulation cylinder body 61, and sea water desalting plant is sunk in seawater; The counterweight sinking in seawater is positioned at column cylinder body and pressure regulation cylinder body below, and column cylinder body and pressure regulation cylinder body are roughly vertical state.
After sea water desalting plant sinks in tens meters of dark seawater, rope can be fixed in liferaft.Sea water desalting plant utilizes the hydraulic pressure of seawater itself to make seawater see through annular reverse osmosis rete 22 as pressure source and enters desalination water storage chamber 23, thereby obtains drinkable desalination water.
Simultaneously, the first cavity 64 interior automatic formation negative pressure of the hydraulic pressure that negative pressure adjusting device 6 utilizes seawater between first piston 63 and the second pressure regulation through hole 62, as follows in detailed process: seawater and hydraulic pressure enter in the cavity between the second piston 65 and the 3rd piston 68 by the first pressure regulation through hole 67, because the cross-sectional area of the 3rd piston is greater than the second piston, thereby the 3rd piston is moved down, and drive first piston 63 and the second piston one is logical moves down.In the first cavity in the process moving down at first piston between first piston and the second pressure regulation through hole, form negative pressure, and pass through pressure-regulating pipe 7 in the interior formation negative pressure of desalination water storage chamber 23, further improve seawater and see through the speed that annular reverse osmosis rete enters desalination water storage chamber, at least improve the desalination efficiency of twice.
Desalination water in desalination water storage chamber 23 covers after the first radial hole, and desalination water will flow in axial passage, and makes float ball 8 floatings; In float ball floats to tapered channel 252, and after being resisted against on tapered channel inwall, float ball is stopped up tapered channel, thereby desalination water storage chamber 23 and the first cavity of negative pressure adjusting device are separated.After this, when the desalination water in desalination water storage chamber 23 increases gradually, the pressure in desalination water storage chamber will increase and be greater than a standard atmosphere gradually; Pressure in desalination water storage chamber is greater than after a standard atmosphere, and first piston body 27 and the first movable push rod 210 will move down gradually.At the first movable push rod, move down after a segment distance, the movable push rod 43 of promotion the 3rd and the 3rd piston body 49 are together moved down; When the 3rd piston body moves down after a segment distance, waterway channel 412 will be communicated with extraneous seawater; Now seawater and hydraulic pressure enter and discharge in cylinder body 41, and the second piston body 42 and the second movable push rod 45 are moved toward the direction away from fixed stop 46, and the second movable push rod is separated with fixed stop; And then counterweight 5 is discharged.
Then, sea water desalting plant floating, for the crewman in liferaft provides emergency water supply.
After desalination water in desalination water storage chamber 23 is derived by drain outlet, first piston body 27 resets under the first preloading spring 29 effects.First, second and third piston resets under retracing spring 610 effects.
Sea water desalting plant of the present invention not only can be in process be sought survival in the perils of the sea failure-free provide emergent water for people, and do not need to depend on electric power and supply with, its functional reliability, stability are high.
