Abstract

The invention discloses a solar photovoltaic photothermal distribution type negative pressure seawater desalination device. A photovoltaic array converts solar energy into electric energy which respectively supplies power to a vacuum pump and a heater through a DC / DC converter, and a controller respectively controls a vacuum pump and a seawater pump according to the signals of a pressure sensor and a liquid level sensor in order to adjust the pressure and the liquid level height of a sweater pool. The seawater pool, a glass cover and a freshwater return tank form a sealing body, the heater is arranged at the bottom of the sweater pool in a sealing manner, the electrified heater heats seawater, evaporated freshwater is condensed on the internal surface of the glass cover, and the condensed freshwater flows to the freshwater return tank, then flows into a freshwater outlet and reaches a freshwater lead-out valve to finally obtain clean freshwater.

Description

technical field [0001] The invention relates to a solar photovoltaic photothermal distributed negative pressure seawater desalination device, which utilizes solar photovoltaic power generation and photothermal technology to achieve high-efficiency seawater desalination, and belongs to the technical field of new energy applications. Background technique [0002] With the rapid development of modernization construction, the rapid expansion of the population, and the great improvement of people's material and cultural living standards, the amount of water is increasing day by day, but the amount of water supply has not increased, and water pollution has become increasingly serious. Therefore, the global and national water supply contradictions have become increasingly prominent. Human beings are facing increasingly severe challenges from the two major crises of water resources and water quality. Therefore, the rational development and utilization of water resources and the eff...
