Problems solved by technology

The disadvantage of this method is that the design is more complicated, the construction cost is higher, and the utilization rate of solar energy is lower, because some heat still flows into the air

Embodiment Construction

[0038] The following embodiments utilize an important principle, that is, the chimney effect. The so-called chimney effect refers to the phenomenon that indoor gas rises or falls along a space with a vertical slope, causing the gas to strengthen convection. The most common chimney effect is that when the furnace and boiler are in operation, the hot gas generated rises up the chimney and leaves at the top of the chimney. The draft caused by the escape of hot gases from the chimney draws air from the outside in to fill the fire, making the fire even more intense. Thereby enhancing the convection of gas. So in general, the pressure difference is greatest near the bottom of the chimney and the velocity of the gas is greatest. The chimneys described in the following embodiments all refer to devices that can play a chimney effect. So the chimney devices referred to in the following embodiments include solar chimneys, and other devices that can play a chimney effect. In addition,...

Abstract

The invention relates to a two-channel chimney device, a seawater desalting device and a method for forming two airflow channels. The two-channel chimney device comprises a heating chamber, an ascending air channel communicated with the heating chamber, and a descending air channel, wherein an outlet of the descending channel is communicated with the heating chamber, air flow paths among the descending air channel, the heating chamber and the ascending air channel enable gas, which is expanded under heating, in the heating chamber to enter the ascending air channel by virtue of a chimney effect, and gas is also introduced into the heating chamber through the descending air channel. By virtue of the two-channel device, heat energy generated by desalting seawater can be efficiently reused, and the loss of heat in the heating chamber can be reduced. According to the invention, the defects of seawater desalting by solar energy in the prior art are overcome, the seawater desalting ratio is improved, the energy consumption is reduced, and the construction and maintenance costs are low.

Description

technical field [0001] The invention relates to the technical fields of energy utilization and seawater desalination, in particular, the invention relates to a method and a device for desalinating seawater by using solar energy. Background technique [0002] The water resources on the earth are very abundant, but 97% of them are undrinkable and irrigated seawater, and most of the remaining 3% are Antarctic and Arctic glaciers, which cannot be conveniently used. However, the earth's fossil energy is decreasing day by day, and the days before it will be exhausted are numbered. Therefore, the cost of using fossil energy to desalinate water is too high. Therefore, using natural energy such as solar energy to desalinate water has been a hot topic in the past decade or so. However, although new technologies have been introduced continuously, most of them face constraints in various aspects such as cost and technology and cannot be widely promoted. Nowadays, large-scale desalinate...
