HONEYCOMB PARTICLE HEAT EXCHANGER AND HEAT STORAGE POWER GENERATION SYSTEM

Title:

HONEYCOMB PARTICLE HEAT EXCHANGER AND HEAT STORAGE POWER GENERATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2023/284079

Kind Code:

A1

Abstract:

A honeycomb particle heat exchanger and a heat storage power generation system. The particle heat exchanger comprises heat exchange units. The heat exchange units each comprise a particle channel (11) and water channels (9), wherein the water channels (9) are arranged on one side of the particle channel (11). In the lengthwise direction of the particle channel (11), several heat conduction rods (8) are arranged between the particle channel (11) and the water channels (9), one end of each of the heat conduction rods (8) is connected to one water channel (9), and the other end thereof extends into a side wall of the particle channel (11). The inner wall of the particle channel (11) is provided with a pit (12) at the position of the end of each heat conduction rod (8), the ends of the heat conduction rods (8) are located at the bottoms of the pits (12), and the surfaces of the particle channel (11) and the pits (12) each have a wear-resistant layer. The particle heat exchanger can effectively weaken the wear of an inner wall of the heat exchanger caused by particles, and can thus meet the requirement for solar efficient particle heat storage power generation.
