The exhaust valve being connected with atmosphere is additionally provided on the internal layer water tank.
The condenser pipe is connected to the outer layer water tank.
Sea intake is connected with the water outlet of filter device after the processing, and water inlet and the sterilization of the filter device disappear
The water outlet of malicious device is connected, and the water inlet of the sterilization and disinfection device is connected with seawater.
The heating cylinder is a hollow cylindrical cylinder body.
Cooling fin is provided with outside the internal layer water tank.
Piston is cross-shaped structure, upright guide rail band piston pump and will be divided into heating cylinder two it is closed
Space.
Working principle of the present invention is as follows: it is extra large after the pretreated seawater of the techniques such as sterilization, disinfection, filtering is from processing
Water inlet is flowed into the outer layer water tank of cooling water tank, the outer layer water tank of water tank to be cooled full of after seawater, opening water pump, seawater from
The seawer outlet of cooling water tank flows to the sea intake of heating cylinder, and the seawater in heating cylinder is entered by flow control valve control
Amount.Stream due to being divided into two confined spaces up and down in heating cylinder, before piston moves downward in cross, by the confined space of upper layer
Control valve is opened, and flow control valve sprays into suitable extra large water and air, and piston moves downward for cross later, upper layer confined air
Interior pressure reduces, and the boiling point of water certainly will reduce in the space.Before this, the electric heating wire heating cylinder in heating cylinder interlayer
Body, the temperature in heating cylinder increase, and reach the boiling point of water after the pressure drop of upper layer confined space in heating cylinder, instant water is vaporized into steaming
Vapour.Later, cross piston moves upwards under the driving of mechanical transmission mechanism, and the flow control valve in the confined space of upper layer closes
It closes, pressure rise in confined space, the check valve of upper layer confined space is opened under the extruding of vapor, vapor flow direction cooling
The internal layer of water tank, meanwhile, the flow control valve by lower layer's confined space of heating cylinder is opened, suitable extra large water and air is sprayed into,
Pressure in lower layer's confined space reduces, and the boiling point of water equally reduces, and seawater is vaporized into steam, when cross piston downlink,
Vapor push is entered to the internal layer of cooling water tank.Under the action of cooling water tank outer layer Mare Frigoris water and condenser pipe, vapor
It is condensed into fresh water.Cooling water tank can be discharged by the exhaust valve of cooling water tank upper end in uncooled vapor and air.Later, cold
But the warm seawater of water tank outer layer becomes the fresh water in cooling water tank internal layer by the circulation of above procedure in cycles.Machinery passes
Motivation structure is connected with rotation blower, converts wind energy into the mechanical energy that cross piston pumps, in heating cylinder interlayer
Electric heating wire consumption tide energy hydraulic generator of the electric energy from seashore.
A kind of electric heating piston reciprocating type seawater desalination system provided by the invention, the setting of cross piston, piston are past
Multiple movement, necessarily makes two inside heating cylinder confined space air pressure one to become larger, one becomes smaller, the confined space that air pressure becomes smaller
Seawater boiling point is lower, therefore fresh water output capacity is high, and it is high to improve energy utilization rate；Cross reciprocating motion of the pistons, and two are closed
Space is provided with the setting of sea intake and steam outlet, efficiently utilizes piston motion, and difference is close when making piston up-down
Sea water desalination can be carried out by closing space, therefore sea water desalination speed is fast, less energy consumption, the present invention using piston the life that pumps
Produce fresh water, fresh water output capacity is high, and structure is simple, can practicality it is strong；The setting of blower and tide energy hydraulic generator is rotated,
So that the present invention is utilized the renewable resource on seashore, realizes zero-emission, contamination-freely sea water desalination, energy-saving and emission-reduction；Cooling water tank point
Inside and outside two layers of setting, internal layer is for containing and condensing fresh water, and outer layer is for seawater after containing and heating, seawater after processing
Into after outer layer water tank, becomes warm seawater to seawater heating after processing using the temperature of internal layer tank outer wall, avoid vapor
The waste of residual temperature, and seawater accelerates the condensation speed of vapor with the vapor generation heat exchange in internal layer water tank after processing
Degree and condensation effect, to be diluted processing seawater water source of the warm seawater as heating cylinder reduce the energy utilization of electric heating wire, therefore
Energy utilization rate of the present invention is high, avoids the waste of vapor heat；The setting of cooling fin has further speeded up the cold of vapor
Solidifying speed and condensation effect, have also further speeded up the heat exchange process of seawater after processing, keep fresh water output capacity high, improve the energy
Utilization rate；The setting of filter device and sterilization and disinfection device makes the present invention have sterilization, disinfection, filtering function, removes in seawater
Impurity, ensure the service life of equipment, and the seawater safety and sanitation after desalinating.
