Solar energy water heating auxiliary heat storage device and power plant boiler solar energy water heating supply system formed from solar energy water heating auxiliary heat storage device

摘要

PROBLEM TO BE SOLVED: To provide a solar energy water heating supply system for a power plant boiler (1) formed from a solar energy water heating auxiliary heat storage device and a solar energy water heating auxiliary heat storage device. A solar energy water heating auxiliary heat storage device includes at least one molecular sieve heat storage bed (18) and a heat storage water tank (17). The molecular sieve heat storage floor (18) includes a cylindrical heat storage floor outer casing (18.1) and several heat storage tubes (18.5) provided in the heat storage floor outer casing (18.1). Each heat storage tube (18.5) consists of a metal tube (18.5.1) having a mesh and an absorbent layer (18.5.2) attached to the surface of the metal tube (18.5.1) having a mesh for heat storage. ). The absorbent material of the absorbent layer (18.5.2) is a molecular sieve absorbent material that can be compatible with water to act as a working medium pair. This system can sufficiently use solar energy as an auxiliary fuel for the boiler (1) of the power plant, so that the normal operation of the boiler (1) is not affected by the instability or intermittency of solar energy, and the cost of the power plant Is greatly reduced.
