Problems solved by technology

[0003] Existing solar power generation and seawater desalination devices, such as patent 200810021605.3 discloses a chimney power generation and seawater desalination device using solar energy. The solar power generation and solar seawater desalination devices are combined, although the conversion efficiency of solar energy is improved. At the same time, it can add fresh water output, making seawater desalination more economical, but because the transparent cover is used to condense water vapor into fresh water, the utilization efficiency is low, resulting in unnecessary waste of heat energy

Abstract

The invention discloses a condenser for a chimney type solar electricity generating and seawater desalting device. The condenser is located in a flow guiding cavity of a horn-shaped heat collecting shed; the condenser comprises multiple layers of heat exchanging tube bundles which are arranged along the inner wall of the heat collecting shed in an arc shape; each layer of heat exchanging tube bundles is arranged at an interval; the top end of each layer of heat exchanging tube bundles is communicated with a flow distributing pipe; water pumps are used for introducing seawater in a seawater pool into the flow distributing pipes; the tail end of each layer of heat exchanging tube bundles is communicated with a flow converging pipe; outlets of the flow converging pipes are communicated with seawater heat accumulating layers located at a bottom; a freshwater gathering groove is arranged below the tail end of each layer of heat exchanging tube bundles; each layer of the freshwater gathering grooves is communicated through a flow guiding inner pipe which is arranged vertically; outlets of the flow guiding inner pipes are provided with freshwater flow guiding grooves; the tail ends of the freshwater flow guiding grooves are communicated with freshwater storing pools. According to the condenser, the seawater is used as cooling liquid; not only is the seawater utilized to realize the condensation of wet hot air and the separating out of freshwater, but also a preheating effect on the seawater is achieved; the heat exchanging effect is strengthened.

Description

technical field [0001] The invention relates to the technical field of power generation and seawater desalination by utilizing solar energy, in particular to a condenser for a chimney-type solar power generation and seawater desalination device. Background technique [0002] In today's increasingly scarce fresh water resources, the use of solar energy to desalinate seawater or brackish water has attracted more and more attention. [0003] Existing solar power generation and seawater desalination devices, such as patent 200810021605.3 discloses a chimney power generation and seawater desalination device using solar energy. The solar power generation and solar seawater desalination devices are combined, although the conversion efficiency of solar energy is improved. At the same time, fresh water can be added, making seawater desalination more economical. However, due to the need for transparent cover plates to condense water vapor into fresh water, the utilization efficiency i...
