Siphon air-cooling tower-type solar thermal power generation device with exhaust valve

Abstract

The invention provides a siphon air-cooling tower-type solar thermal power generation device with an exhaust valve. The siphon air-cooling tower-type solar thermal power generation device is composed of a reflecting mirror array, a vertical tower, a tower-top heat collector, a steam turbine and a cylindrical condenser, wherein the bottom and the upper end of the cylindrical condenser respectively comprise an air inlet channel and an air outlet channel; an exhaust-steam condenser is arranged in the cylindrical condenser; and the air inlet channel, the interior of the cylindrical condenser and the air outlet channel constitute an air channel. The siphon air-cooling tower-type solar thermal power generation device is characterized by comprising an automatic valve at the top end of the exhaust-steam condenser. The siphon air-cooling tower-type solar thermal power generation device has the beneficial effects that the air inlet channel, the interior of the cylindrical condenser and the air outlet channel constitute the air channel and a siphon effect is used to realize forced air cooling. Compared with water cooling, the forced air cooling has the advantages of no need of power and cooling water, greatly reduced investment and site selection conditions, capabilities of saving operation cost and high reliability. The automatic valve is arranged at the top end of the exhaust-steam condenser, and the outer end of the automatic valve is communicated with a negative pressure source so as to remove noncondensable gas in the steam turbine. Four embodiments are presented with combination of attached drawings.

Description

technical field [0001] The invention relates to a siphon air-cooled tower type solar thermal power generation device with an exhaust valve. Background technique [0002] Promoting the use of solar thermal power generation is conducive to energy conservation, emission reduction and sustainable development of human beings. There is a solar thermal power generation device using a condenser mirror array, which is cooled by water. Due to the large water consumption, it increases the difficulty of site selection for its construction site, and increases investment and recurring costs. Contents of the invention [0003] The purpose of the present invention is to provide a siphon air-cooled tower solar thermal power generation device with an exhaust valve. [0004] The technical scheme adopted by the present invention to solve its technical problems: use an automatic tracking focusing mirror array, a vertical tower, a heat collector at the top of the vertical tower, a steam turbi...
