Abstract

The invention discloses a solar hot water auxiliary heat storage device which comprises at least one molecular sieve heat storage bed and a heat storage water tank. The molecular sieve heat storage bed comprises a barrel-shaped heat storage bed outer shell, a plurality of heat storage tubes are arranged in the heat storage bed outer shell, and each heat storage tube is composed of a metal tube with meshes and an absorbent layer attached to the surface of the metal tube with the meshes and is used for heat storage. Absorption materials in the absorbent layer are molecular sieve absorption materials which are used as a heat storage working media pair together with water. The invention further discloses a power plant boiler solar hot water supply system constituted by the solar hot water auxiliary heat storage device. Solar energy can be fully used as the postcombustion of a power plant boiler, normal operation of the boiler is not influenced by the instability, the intermittence and the like of solar energy, and the cost of a power plant is obviously lowered.

Description

technical field [0001] The invention relates to a water supply system for a boiler in a power plant, in particular to a solar hot water auxiliary heat storage device, and a power plant boiler solar hot water auxiliary supply system including the heat storage device. Background technique [0002] At present, the world's energy is in short supply, but boilers, especially boilers in large power plants, are consuming a large amount of various energy sources such as coal, natural gas and biomass every day. As solar energy, due to its instability and intermittency, etc., it has not been included in the ranks of boiler fuels. With the development of science, solar medium-temperature collectors have been developed, and energy storage technology has also improved, making it possible for solar energy to be used as a supplementary fuel for boilers. [0003] Taking biomass power plants as an example, solar energy as a supplementary fuel for their boilers has very special significance f...
