8. a kind of fixedly bar shaped minute surface sun energy line optically focused combination sea water desalinating plant as claimed in claim 1 is characterized in that, all control valves all adopt battery valve and Access Control circuit; The quantity of described hot tube heat exchanger is determined according to heat; Below the described solidifying air chamber water discharge valve is housed; All be provided with thermal insulation layer in the middle of described gas drive piston and the hydraulic efficiency piston.
9. the desalination method that adopts such as the arbitrary described a kind of fixedly bar shaped minute surface sun energy line optically focused combination sea water desalinating plant of claim 1-8 is characterized in that, the specific works step is:
Step 1: first fresh-water tank and pipeline are full of pure water and Exhaust Gas before starting, are full of seawater in two hydro-cylinders;
Step 2: to glass metal valve tube resorber, resorber is followed the tracks of sun line optically focused to the stripe-shape plane speculum of fixed bar shaped minute surface reflecting and condensing device with the sun power line reflection; Behind the resorber of pure water through sun energy line optically focused, be heated to form 110-150 ℃ of saturated wetting vapour, reach the vapor pressure about 1.43-4.76bar;
Step 3: the breather cheek valve of opening a steam driven seawater supercharging device, close one-way exhaust valve and the water intaking valve of this steam driven seawater supercharging device, steam enters the pneumatic cylinder of this steam driven seawater supercharging device, expand and do work, promote hydraulic efficiency piston by piston rod, the hydro-cylinder rate of supercharging is 36:1; When steam reaches certain pressure, Steam Actuation gas drive piston, thus promote hydraulic efficiency piston compression seawater through the intermediate piston bar, enter reverse osmosis desalination device through the seawater after the supercharging and produce fresh water and strong brine; When the hydraulic efficiency piston of steam driven seawater supercharging device moves to the cylinder body right-hand member, steam off drives the breather cheek valve of seawater supercharging device, open one-way exhaust valve and the water intaking valve of steam driven seawater supercharging device, steam enters solidifying air chamber and condenses into water through hot tube heat exchanger, forms negative pressure and makes seawater be easy to again be full of hydro-cylinder; Another steam driven seawater supercharging device was started working when hydro-cylinder was filled, and the method for work of another steam driven seawater supercharging device is consistent with the method for work of above-mentioned steam driven seawater supercharging device; Alternate cycles like this;
Step 4: the steam of discharge is condensed into water through the hot tube heat exchanger between solidifying air chamber and the evaporator room, arranges to fresh-water tank by the check valve of pipeline, and the water of fresh-water tank enters resorber by water circulating pump and again is heated into steam by optically focused; Evaporator room makes seawater obtain rapid evaporation through the heat exchange of hot tube heat exchanger, spray and the injector suction of nozzle simultaneously, and secondary steam enters condensing chamber and is condensed into the fresh water discharge; Cooling room obtains pre-hot sea water by the warm air cooling to gas drive piston the right in piston rod and the pneumatic cylinder.
10. a kind of fixedly bar shaped minute surface sun energy line optically focused as claimed in claim 9 makes up method for desalting seawater, it is characterized in that, described hot tube heat exchanger produces negative pressure to the steam of discharging in solidifying air chamber condensation, and seawater automatically refills hydraulic cylinder body, flashes to secondary steam in the heat absorption of evaporator room seawater; Described injector produces vacuum tightness to the evaporator room gas injection, accelerates evaporation; The injector injection forms saturated low-pressure steam, enters cooling room through seawater condensing, produces fresh water and discharges, and seawater preheating enters evaporator room.
