Embodiment

[0006] Embodiment: A method for using seawater desalination. Seawater evaporators, heating facilities, water vapor liquefiers, and water-cooled dense layout coils are arranged in the hull, and the cold seawater in the facilities is taken from normal temperature seawater, and the seawater is allowed to flow through the water pump. The cooling facility cools the high-temperature water vapor in the steam liquefier in the form of bottom-up flow; the seawater flows out from the upper part of the cooling facility, flows out of the hull all the way, returns to the sea from the seawater outlet, and enters the seawater through the water valve to evaporate in the other way In the seawater evaporator, when the heating device at the lower part of the seawater evaporator heats it to boiling, a large amount of water vapor is generated and precipitated from the upper surface of the seawater, and then introduced into the upper part of the water vapor liquefier from the top pipe of the seawater ...

Abstract

The invention relates to a method for seawater desalination. A seawater evaporator, a heating device, a steam liquefier and a water-cooled densely layout pipe coil cast are arranged in a ship body, cold seawater in a cooling facility is taken from normal temperature seawater, high temperature steam in the steam liquefier is cooled by the seawater which flows from down to up in the cooling facility through a water pump; the seawater flows out from the upper part of the cooling facility, one current flows out of the ship body and returns to the sea from a seawater outlet, the other current enters the seawater evaporator by a water valve and is heated to be boiling by the heating device at the lower part of the seawater evaporator, a large amount of steam is precipitated from the upper surface of seawater and is guided to the upper part of the steam liquefier from the top pipe of the seawater evaporator, the steam is liquefied to fresh water from up to down after down-up cooling effect of normal temperature seawater; and the fresh water is transported to a fresh water pipe network from a fresh water output port through a fresh water transportation pipe. The beneficial effects of the method are as follows: ensuring the fresh water to be output with high quality and high efficiency from the raw material seawater and saving energy.

Description

technical field [0001] The invention relates to a method for using seawater desalination. Background technique [0002] At present, the most commonly used seawater heating distillation condensation method for seawater desalination, or seawater heating multiple distillation condensation method, often occurs that the water temperature rises and interrupts the production of fresh water, which is inefficient and consumes energy. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a seawater desalination method. [0004] The technical solution of the present invention is: a method for using seawater desalination, which is characterized in that seawater evaporators, heating facilities, water vapor liquefiers, and water-cooled densely arranged coils are arranged in the hull, and the cold seawater in the facilities is taken from Normal-temperature seawater, through the water pump, the seawater cools the high-te...
