Method and system for comprehensive utilization of straw with solar thermal energy storage for heating

Abstract

The invention belongs to the technical field of solar energy utilization, and provides a solar light-heat energy storage heating straw comprehensive utilization method. The solar light-heat energy storage heating straw comprehensive utilization method comprises the following steps that S1, the fact that heat sources are consumed by heating in a heating season and straw processing in a non-heatingseason is determined, the heat sources are wave-trough-electricity electric heat and solar light heat in a lighting area, and an energy storage mode is that energy storage is conducted by an energy storage tank; S2, during the heating season, the lighting area is predicated by satellite cloud picture data in the first day, a could layer thickness M is predicated in the second day, the cloud layerthickness M in the second day in the lighting area serves as an independent variable, and a dependent variable U of the solar light-heat heat source second-day predicated collection amount and a dependent variable Q1 of the heating season second-day heat source predicated consumption amount are obtained through calculation; a constant Q2 of the non-heating season second-day heat source consumptionamount is set out; and S3, an energy storage capacity C of wave trough electricity stored in the energy storage tank in the first day is determined, during the heating season, the formula of C=k(Q1-U) is applied, and during the non-heating season, the formula of C=k(Q2-U) is applied. According to the solar light-heat energy storage heating straw comprehensive utilization method, the technical problem that in the prior art, the solar light heat and the wave trough electricity are only simply utilized, and accurate utilization cannot be conducted is solved.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and relates to a comprehensive method and system for utilizing solar photothermal energy storage and heating straw. Background technique [0002] In the global environment of promoting clean energy, solar thermal power generation is the new energy that is most likely to replace thermal power as the basic power load, and the trough solar thermal power generation technology is the most stable and mature among the four technologies of solar thermal power generation.
