Cyclone separation type particle heat exchanger and heat storage power generation system

Abstract

The invention discloses a cyclone separation type particle heat exchanger and a heat storage power generation system. The cyclone separation type particle heat exchanger comprises an outer cylinder and a plurality of water channels, the side walls of the two ends of the outer cylinder are connected with a high-temperature particle-air mixture inlet and a high-temperature particle-air mixture outlet which are tangent to the outer cylinder correspondingly, the multiple water channels and the outer cylinder are coaxially arranged and penetrate through the bottoms of the two ends of the outer cylinder, the water channels are in sealed connection with the bottom of the outer cylinder, and wear-resistant layers are arranged on the inner surfaces of the outer cylinder, the high-temperature particle air mixture inlet and the high-temperature particle air mixture outlet. Abrasion of particles to the heat exchanger can be effectively avoided and weakened, and the requirement for solar efficient particle heat storage power generation is met.

Description

technical field [0001] The invention belongs to the field of new energy physical heat storage and power generation, and relates to a cyclone separation particle heat exchanger and a heat storage and power generation system. Background technique [0002] Energy is the cornerstone of the existence and development of modern society. With the continuous development of the global economy and society, energy consumption also continues to grow accordingly. As time goes by, the scarcity of fossil energy becomes more and more obvious. In the context of the increasingly tense supply of fossil energy, the large-scale development and utilization of renewable energy has become an important part of the energy strategy of various countries in the future. Solar energy is an inexhaustible renewable energy for human beings. It has sufficient cleanliness, absolute safety, relative extensiveness, long life and maintenance-free, resource adequacy and potential economy. It has an important pos...
