Abstract

The invention provides a solid heat storage system and a solid heat storage method. The solid heat storage system comprises n solid heat storage heat exchangers, a main pipeline and a bypass pipeline, wherein the n solid heat storage heat exchangers are marked as the first solid heat storage heat exchanger, the second solid heat storage heat exchanger... and the nth solid heat storage heat exchanger, and the n is a natural number; the main pipeline comprises a heat side main pipeline body, a first main pipeline body, a second main pipeline body ... an (n+1)th main pipeline body and a cold side main pipeline body; the first solid heat storage heat exchanger, the second solid heat storage heat exchanger... and the nth solid heat storage heat exchanger are sequentially connected in series through the main pipeline. The solid heat storage system is low in price, easy to operate, safe and stable, is not only suitable for heat storage and heat exchange of a large solar thermal power station heat storage system, but also suitable for heat storage of unstable industrial waste heat recovery, and has great significance in full utilization of renewable energy sources and waste heat.

Description

technical field [0001] The invention relates to a heat storage system, in particular to a solid heat storage system and a solid heat storage method. Background technique [0002] With the shortage of conventional energy and the improvement of people's requirements for environmental quality, renewable energy, especially solar energy, is more and more popular. At the same time, the large amount of waste heat generated by industrial production is also the focus of comprehensive energy utilization in the future. [0003] Whether it is solar energy or industrial waste heat, the biggest shortcoming is the instability of energy supply. Combining solar thermal power generation and industrial waste heat with heat storage systems increases the stability and availability of solar and industrial waste heat output. [0004] However, the existing heat storage system has problems such as limited stability of heat output, high cost, complex structure, and inflexible operation scheduling, w...
