Problems solved by technology

However, in these patents, the brine pool is directly arranged under the heat collection shed. When the solar energy heats the heat collection shed, a large amount of energy will be consumed in the evaporation of brine, thereby losing a lot of energy, and at the same time reducing the change in the density of the steam in the heat collection shed. , which in turn affects the airflow velocity into the chimney and reduces the freshwater production rate
At the same time, the heat-collecting sheds described in these patents are all in the form of non-light concentrating. In order to make more seawater desalination, a larger heat-collecting shed area is required.

Abstract

The invention discloses a double chimney tracking solar energy sea water desaltation system and a desaltation method thereof. A heat collection shed arranged horizontally is connected with an inner chimney; a trough-type light-focusing module arranged aslant is connected with an outer chimney; the height of the outer chimney is higher than that of the inner chimney; a wind turbine is arranged at the bottom of the inner chimney; a liquid separating device is arranged in the dividing wall between the inner chimney and the outer chimney; a condenser is arranged in the inner chamber channel and on the outer surface of the outer chimney; the solar energy heating horizontal heat collection shed generates air flow; the air flow pushes the wind turbine at the bottom of the inner chimney to provide part electrical energy needed by the system; the trough-type light-focusing module heats the seawater to generate water vapor; the air flow in the inner chimney injected water vapor flows to the condenser, and is condensed to fresh water; the fresh water flows in a fresh water tank along the outer chimney wall; strong brine with a relatively high temperature flows in a horizontal heat collection shed bottom heat storage layer to store energy. The solar energy sea water desaltation system and the desaltation method have the advantages that light-focusing solar energy is utilized to heat the seawater; the structure is compact; power source and capacity source are separated from each other reasonably; solar energy can be utilized and managed better, and the fresh water productivity can be improved.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and relates to a solar thermal seawater desalination method, in particular to a double-chimney tracking solar seawater desalination system and desalination method. Background technique [0002] The per capita share of fresh water resources in my country is about 2200m 3 , 1 / 4 of the world's average level, is listed by the United Nations as one of the thirteen most water-deficient countries. Our country is a big ocean country with a long coastline, and we can use solar energy to desalinate seawater. There are more than 20 types of solar desalination technologies, and there are two main methods: one is to use solar power to drive the reverse osmosis process; the other is to use solar energy to generate heat to distill seawater to make it evaporate through phase change. The solar reverse osmosis method requires high-pressure pumps, reverse osmosis membranes, heat exchangers, condense...
