Description

technical field [0001] The invention belongs to the field of seawater desalination and central heating, and in particular relates to a pure hot distilled water preparation device and method. Background technique [0002] With the rapid development of my country's economy and society and the continuous advancement of urbanization, the shortage of water resources has become an important factor restricting the sustainable development of my country's society and economy. my country's per capita water resources are only a quarter of the world's per capita water resources, and China is one of the countries with the poorest per capita water resources in the world. Desalination of seawater is an effective means to increase the amount of water resources from the source, an important way and strategic choice to solve the shortage of water resources in my country, and an inevitable requirement to ensure national security and sustainable development. Seawater desalination technology ha...
