Novel heat collection type hot air flow power generation system

Abstract

The invention discloses a novel heat collection type hot air flow power generation system, and relates to the technical field of new energy power generation. The existing technical problems are solved. The novel heat collection type hot air flow power generation system comprises a base, a chimney is arranged on the base, the chimney comprises a chimney inner wall, a chimney outer wall is arranged on the outer side of the chimney inner wall, and a heat preservation layer is arranged on the outer side of the chimney outer wall; and a power generator and a power generator bearing frame are arranged in the chimney, the power generator and the power generator bearing frame are provided with a hot air flow turbine and a cyclone through a power generator shaft, an air heater is arranged in the chimney, and the air heater is connected with a heat storage system. A steam turbine and a water treatment system, a steam system, a condensation system, a water supply system and the like matched with the steam turbine are abandoned, system equipment is greatly reduced, the structure is simpler, the investment cost is lower, and the operation and maintenance cost is lower. Meanwhile, the system does not need to use water as a working medium so that the system can be installed in Gobi deserts and even desert areas which are good in illumination condition and free of water resources.

Description

technical field [0001] The present invention relates to the technical field of new energy power generation, and more specifically relates to the technical field of a novel heat-collecting hot air flow power generation system. Background technique [0002] In the next few years, a large number of wind power and photovoltaic power will be connected to the grid one after another, which will further weaken the regulation and control capability of the power grid. Because the cost of heat storage is much lower than other forms of energy storage, solar thermal power generation can not only be used as a continuous and stable power source to supply power to the grid, but also can be used as a dedicated heat storage peak-shaving power plant. Photothermal power generation will occupy an indispensable position in the clean energy sector because of its heat storage and peak-shaving capabilities that wind power and photovoltaic power generation do not have.

Problems solved by technology

This way of working has high investment costs, complex systems, high failure rates, and high operation and maintenance costs. Moreover, most solar thermal power generation systems are installed in the arid and water-scarce areas of the Gobi Desert in Northwest China. Steam turbines require a lot of water resources, which increases the operating costs of the system.
