Abstract

The invention discloses a small-size flash evaporation type seawater desalting device, relates to a seawater desalting device, in particular to the small-size flash evaporation type seawater desaltingdevice, and aims to solve the problems that a conventional flash evaporation type seawater desalting device is complex in structure, large in size and not applicable to small-size on-scale seawater desalting demands. The small-size flash evaporation type seawater desalting device comprises a vacuum container and a cover plate, wherein the cover plate is horizontally arranged at the upper part inside the vacuum container. The small-size flash evaporation type seawater desalting device further comprises a tube plate, an inner condenser, a first connecting tube, a second connecting tube, a guidecomponent, a third connecting tube and a plurality of heat exchange tubes, wherein the cover plate, the tube plate and the inner condenser are mounted in the vacuum container from top to bottom in sequence; the plurality of the heat exchange tubes are fixedly mounted on the tube plate; the inner condenser is connected with the guide component; the first connecting tube is mounted at the lower part of the outer side wall of the vacuum container; the second connecting tube is mounted on the lower surface of the vacuum container; and the third connecting tube is mounted on the upper surface of the vacuum container. The small-size flash evaporation type seawater desalting device belongs to the field of seawater desalting equipment.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a small flash type seawater desalination device, which belongs to the field of seawater desalination equipment. Background technique [0002] UN experts estimate that 1.0-1.5 billion people on the planet lack drinking water, and more regions or countries will face the problem of reduced development speed and quality of life due to water shortage. The shortage of fresh water resources in my country's coastal cities has become more and more urgent, and the country has continuously adopted various measures to make up for the huge gap between the shortage of fresh water resources and the rapid economic development. At this stage, the South-to-North Water Diversion Project has sparked controversy among many experts and scholars, and the project is facing a great test. Like coastal cities, which are rich in seawater resources, they should make full use of seawater and take desalinatio...
