Solar tower type focusing high temperature heat collection steam boiler-turbine electric generating apparatus

Abstract

The invention relates to a solar tower-typed high temperature-focusing heat-collecting steam boiler-steam turbine generating device; the device arranges solar heat-collecting units with the number of n on the ground around a tall tower; each solar heat-collecting unit consists of a plane reflector, a solar tracing sensor and a control mechanism thereof, traces the sun and reflects the sunshine of different positions to the focus position of the top of the tower, namely around the solar steam boiler; the solar steam boiler is heated to generate pressure steam to drive the steam turbine to rotate for driving the generator to generate alternating current which is used on-line after the transformation by a transformer.

Description

Technical field [0001] The invention relates to a solar tower-type focused high-temperature heat-collecting steam boiler-steam turbine power generation device, especially in sunlight, the device can use sunlight to focus on a large area of ​​the tower to heat the boiler at high temperature, and can obtain high temperature, high pressure, and large steam volume The steam drives steam turbines and generators to generate electricity. Background technique [0002] At present, the known solar power generation device, its structure or the pn junction photovoltaic effect that is made up of semiconductor material sends the direct current power from the solar cell panel that generates electricity under sunlight; ), or an integral solar collector (common solar cooker) composed of a spherical or cylindrical focusing plate, which is fixedly placed on the ground to receive sunlight to generate hot water or boiling water, and cannot obtain high-temperature and high-pressure steam to drive...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing solar panel power generation device, the obtained power is low in efficiency, high in cost, and needs to be converted into alternating current before it can be connected to the grid. Its control mechanism is a solar reflection heat collection array plate composed of each unit. This array plate can reflect and focus sunlight in a large area to the solar steam boiler installed on the top of the tower in a large area under the sun. The high temperature solar heating boiler The water in the water produces high-pressure steam, and the high-pressure steam drives the steam turbine to rotate, and the steam turbine drives the generator to generate the AC power we commonly use.
