Energy-saving and high-efficiency seawater desalination device

Abstract

The invention discloses an energy-saving and high-efficiency seawater desalination device including an evaporator, a freshwater tank, a condenser and a heat exchanger. The interior of the evaporator is provided with the heat exchanger. A water inlet pipe is connected with a water pump, an activated carbon filter and a first valve in turn. One side, close to the water inlet pipe, of the inner wallof the evaporator is provided with an atomizer. A conveying pipe is used for conveying industrial waste heat for the heat exchanger. The top of the evaporator communicates with a steam pipe, the top of the steam pipe is fixedly connected with the condenser, the bottom of the condenser communicates with a water collecting pipe, and the water collecting pipe communicates with the freshwater tank. According to the energy-saving and high-efficiency seawater desalination device, and through a mineral detector and a mineral addition device arranged in the freshwater tank, a proper amount of mineralsubstances are added in distilled water conveniently, so as to meet the requirements of human drinking; the activated carbon filter is used for removing peculiar smell in seawater; with arrangement ofthe heat exchanger, the industrial waste heat is used for heating and evaporating the seawater, the industrial waste heat is used reasonably, and energy conservation and environmental protection areachieved. The heating evaporation is performed after the seawater is atomized, and the evaporation efficiency of the seawater is improved.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to an energy-saving and high-efficiency seawater desalination device, and relates to the technical field of seawater desalination. Background technique [0002] Fresh water resources have an extremely important impact on people's production and life, and are one of the most important material foundations for human survival and development. However, the fresh water resources that can meet the production and living conditions are very limited at present, and the shortage of fresh water resources at home and abroad is becoming increasingly serious. . The ocean contains a large amount of water resources, but it contains a large amount of halogen elements and other substances, so it cannot be directly used by people. At present, the development and utilization of seawater desalination technology has increasingly become an important means to solve the shortage of freshwater resources. ...
