Seawater desalination and solar power generation integrated device with waste heat utilization

Abstract

The invention discloses a sea water desalination and solar power generation integrated device with waste heat utilization, which comprises a chimney, a wind power supercharging device is arranged on the upper part of the chimney, and a solar flexible transparent cell panel is annularly arranged at the bottom of the chimney; the heat collecting surface is annularly and obliquely arranged at the bottom of the chimney, and the heat collecting surface is arranged at the lower part of the solar flexible transparent cell panel; the first flue gas flow channel is coiled on the lower side of the heat collection surface, and a flue gas inlet is formed in the outermost side; one end of the second flue gas runner is connected with the flue gas outlet of the first flue gas runner, and the other end is arranged at the bottom axis of the chimney; the turbine is arranged at the other end of the second flue gas flow channel; the spraying device is arranged above an inner ring of the heat collecting surface and is used for spraying seawater to the heat collecting surface; and fresh water generated on the heat collecting surface is collected through the condensing device. The device has the characteristics of improving the generating capacity and increasing the fresh water output.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, and more specifically, the invention relates to an integrated device for seawater desalination and solar power generation with waste heat utilization. Background technique [0002] As a renewable energy source, solar energy has the advantages of no pollution and abundant resources. It is widely used in heating, power generation and other scenarios to meet the needs of industrial production and life. In today's shortage of fossil energy, solar energy has attracted more and more attention, and the use of clean and renewable energy to achieve sustainable, low-emission production has become one of the focuses of research and production. [0003] A solar chimney is a device that uses solar energy to heat air to generate an updraft effect that drives a turbine to generate electricity. It is generally composed of glass plates, heat collecting plates, tuyere and other materials. The p...
