After reaching certain depth, fluid level control valve 104 opens valve, and seawater flows out from delivery port.Fluid level control valve 104 causes delivery port
The seawater at place plays fluid-tight effect, prevents gas caused by air pump 6 from being flowed out from delivery port.
Vapor gas coming through passage 203, from the space outflow among gas passage 203 and conical lid 202 and to upstream
It is dynamic, condensed on the longitudinal fin on condensation copper pipe 201, condensed water drops to the bottom of cooling cylinder 2 or conical lid along longitudinal fin
On 202, conical lid 202 plays water conservancy diversion, condensed water is flowed to cooling cylinder bottom without passing through gas passage along taper
203 flow back to evaporation tank 1, and this is process of drying.Cooling source of the normal temperature seawater as cooling cylinder 2 in condensation copper pipe, at the same it is hot
Steam condensation liberated heat preheating, after the seawater after preheating enters evaporation tank 1 by shower nozzle 103, the sea in normal temperature seawater case 5
Water continues to inject condensation copper pipe 201, and sink temperature is sufficiently low when ensure that cooling.
A baffle plate is each provided with up and down in fresh water outlet pipeline 401, fresh water is played a part of fluid-tight, prevents steam from light
Water outlet conduit 401 is discharged.The valve of fresh water outlet pipeline 401 is opened, fresh water flows into fresh-water tank 4 from the discharge outlet of cooling cylinder 2.
Gas is circulating system when the system works, and the air of cooling cylinder 2 is extracted out and is transported to conical distributor by air pump 6
In 105, the subnormal ambient that the top of cooling cylinder 2 is formed promote gas in device flowed up from conical distributor 105 and with
Seawater carries out heat exchanging tampering, forms gas circulation.
