Novel vertical type solar chimney power plant multistage turbine electric generating set

Abstract

The invention provides a novel vertical type solar chimney power plant multistage turbine electric generating set, and belongs to the field of thermal power devices. The turbine electric generating set is mainly composed of a vertical channel, a convergence-divergence draft tube, a first stage turbine, a second stage turbine, a turbine fixing bracket, a central rotating shaft, a self-aligning ball bearing, a dual-diaphragm coupling, a double slider coupling and an electric generator, and is suitable for a vertical type solar chimney power plant system. The first stage turbine of the turbine electric generating set can utilize all kinetic energy of a thermal current, the second stage turbine can utilize the kinetic energy transformed by expansion depressurization of thermal energy of the thermal current obtained after flowing past the first stage turbine, and therefore the kinetic energy and the thermal energy contained in the thermal current generated in a vertical type solar chimney power plant are transformed into mechanical energy. The energy conversion efficiency can be greatly improved, and the turbine electric generating set has a guiding significance on popularization of the vertical type solar chimney power plant system and remission of urban energy crisis.

Description

technical field [0001] The invention relates to a novel multi-stage turbine generator set for a vertical solar thermal power station, which belongs to the field of thermal power devices. Specifically, when the air flows through the vertical solar chimney in the vertical solar thermal power station, it absorbs solar heat and forms a bottom-up thermal flow under the action of thermal pressure, so the thermal flow contains thermal energy. and kinetic energy, and then use the multi-stage turbine generator set involved in the present invention to convert the kinetic energy and heat energy in the hot air flow into mechanical energy at the same time, and then convert it into electrical energy through the generator, thereby realizing the energy conversion process. Background technique [0002] The concept of solar thermal power plant system was first proposed in 1978, and later attracted a large number of domestic and foreign scholars to study it. The system mainly consists of four ...

Problems solved by technology

The vertical solar thermal power station is very different from the original solar thermal power station. The vertical solar thermal power station is a small power station with a small wind volume relying on the south wall of the city's high-rise buildings. It needs to use the thermal energy and kinetic energy of the thermal air in the system at the same time. Ouyang Sui's design is not applicable and needs to be redesigned
