Seawater desalination device and method for ships

Abstract

The invention discloses a seawater desalination device and method for ships. The device comprises a box body; a liquid discharge port is formed in the bottom end of the outer wall on one side of the box body; an inlet is formed in the top end of the outer wall on the other side of the box body; two symmetrical guide plates are welded at the inner top end of the box body; the guide plates are inclined; heating plates are arranged at the bottom ends of the inner walls on two sides of the box body; a hollow shaft motor is fixed at the middle part of the top outer wall of the box body through a bolt; a hollow pipe is mounted at the output end of the hollow shaft motor; the hollow pipe is vertically disposed; the bottom end of the hollow pipe extends into the box body; and ring-shaped baffles are respectively on the inner walls on two sides of the box body. The device is simple in structural design; through starting the hollow shaft motor, the hollow pipe rotates under the driving of the hollow shaft motor, so that a triangle pipe is driven to stir slowly and the seawater flows inside the box body, thereby accelerating the seawater distillation and the seawater desalination.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a seawater desalination device and method for ships. Background technique [0002] Sea water is water in or from the sea, sea water is flowing, and the amount of water available to humans is unlimited. Seawater is a veritable liquid mineral, with an average of 35.7 million tons of minerals per cubic kilometer of seawater. Among the more than 100 known elements in the world, 80% can be found in seawater. Sea water is also the source of fresh water on land and the regulator of the climate. The world's oceans evaporate 4.5 million cubic kilometers of fresh water every year, of which 90% return to the ocean through rainfall, and 10% become rain and snow on the ground, and then return to the ocean along the river. A ship is a means of transportation that can sail or berth in waters for transportation or operation. It has different technical performance, equipment and structural t...

Sea water is also the source of fresh water on land and the regulator of the climate. The world's oceans evaporate 4.5 million cubic kilometers of fresh water every year, 90% of which return to the ocean through rainfall, and 10% become rain and snow that fall on the land, and then return to the ocean along the river. A ship is a means of transportation that can sail or berth in waters for transportation or operations. It has different technical performance, equipment and structural types according to different requirements for use. When a ship is driving in the ocean, the crew needs to use fresh water. Seawater is processed and desalinated to form fresh water for human use. However, the existing seawater desalination devices generally use distillation methods. At present, the structure design of the distillation device is complicated, and it needs to go through various distillation processes to desalinate seawater. The process is complicated, the practicability is low, and the distillation time Seawater is easy to form alkali on the surface of the heating plate, which is difficult to clean. If the time is too long, it will easily affect the heating effect and slow down the distillation speed.
