Heat absorbing tower with natural ventilation cooling function

Abstract

The invention belongs to the field of solar power generation and discloses a heat absorbing tower with a natural ventilation cooling function. The heat absorbing tower with the natural ventilation cooling function comprises a tower barrel, a heat absorbing tower equipment room, a steam pipe and a condensed water pipe; the heat absorbing tower equipment room is arranged at the top end of the towerbarrel; an air outlet is formed in the side wall of the upper part of the tower barrel; an air inlet is formed in the side wall of the bottom end of the tower barrel; an air cooling heat radiator system is arranged in the air inlet; and the steam pipe is connected with the condensed water pipe through the air cooling heat radiator system. For a solar power plant, a heat absorbing tower and a cooling tower can be combined into one by using a design of a system for using a tower barrel of a high-rise building heat absorbing tower; a natural ventilation cooling system can be adopted in the solarpower plant to reduce the station service power consumption rate and increase the profit of the solar power plant; as high buildings are not additionally constructed, the shielding loss is reduced; and meanwhile, the project cost is reduced, and the floor space is reduced.

Description

technical field [0001] The invention belongs to the field of photothermal power generation, and relates to a heat absorption tower with natural ventilation cooling function. Background technique [0002] Solar thermal power generation refers to the use of a large-scale array of parabolic or dish mirrors to collect solar thermal energy, reflect the solar thermal energy to the heat absorber at the top of the heat absorption tower, and provide heat through the heat absorber, combined with the traditional turbogenerator process, In order to achieve the purpose of power generation, the use of solar thermal power generation technology avoids the expensive silicon crystal photoelectric conversion process, which can greatly reduce the cost of solar power generation. In order to reduce the shading of sunlight, the cooling system of the main engine of the solar thermal power plant generally adopts a mechanical ventilation cooling tower to reduce the height of the cooling tower, but th...
