Small split-type solar electrostatic atomization seawater desalination device and method

Abstract

The invention relates to a small split-type solar electrostatic atomization seawater desalination device and method. By means of an electrostatic atomization technology, the evaporation efficiency ofthe solar seawater desalination device is improved. The device mainly comprises a condensation chamber, a heat exchange tube, an evaporation chamber, an electrostatic atomization device, a seawater storage tank, a control box and a solar heat collection tube. The electrostatic atomization device atomizes seawater into micron-sized fine particles, the micron-sized fine particles are adsorbed to thesurface of the heat exchange tube under the function of a high-voltage electrostatic field, and after the particle size of droplets is reduced, the surface contact area of the seawater per unit volume is quickly increased, that is to say, the heating area of the seawater is increased. The solar heat collection tube absorbs solar heat energy to heat a heat exchange medium in the heat collection tube, after a set temperature is reached, the control box controls a water pump to make the heated heat exchange medium circulate between the heat collection tube and the solar heat collection tube, thetemperature of the heat exchange tube is increased, and the seawater atomized particles adsorbed onto the heat exchange tube are heated and evaporated by heat; the seawater is evaporated on the surface of the heat exchange tube to generate water vapor, and the water vapor is condensed into fresh water in the condensation chamber.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a small-scale split solar electrostatic atomization seawater desalination device and a method thereof. Background technique [0002] The current mainstream solar desalination methods can be divided into two types: passive and active. Passive equipment has a simple structure, convenient materials, low energy consumption, but low water production per unit area; active devices are mostly equipped with multi-stage flash evaporation, low-temperature multi-effect, etc. The method requires supporting auxiliary facilities, the cost of the whole set of equipment is high, the maintenance is relatively difficult, and a certain amount of energy is required to be consumed, and it is suitable for large and medium-sized seawater desalination equipment. [0003] For example, the Chinese patent announcement number is CN105540709A discloses a seawater desalination device, including a heater, a...
