Abstract

The invention discloses a water heat absorber system applied to a concentrating solar energy belt superheating section. The water heat absorber system applied to the concentrating solar energy belt superheating section comprises a superheater, an evaporator, a steam drum, a descending pipe, an ascending pipe, a water replenishing valve, an air vent valve, a superheated steam valve and a heat absorber water drain valve, wherein the superheater also comprises a plurality of isolating valves for switching evaporation and superheating functions. According to the water heat absorber system appliedto the concentrating solar energy belt superheating section, in the starting stage, the superheater assumes the function of the evaporator, so that the processes of heating and boosting water in the heat absorber are improved, and the utilization rate of solar energy is improved; due to the evaporative cooling of a working medium in the superheater, the risk of overheating of the superheater in the starting stage is eliminated, and the reliability of the heat absorber is improved; and the switching between the functions is convenient and rapid, the influence on the operation of the heat absorber system is greatly reduced to an extent and can be almost ignored.

Description

technical field [0001] The invention relates to the field of concentrating solar heat utilization and industrial heating, in particular to a water quality heat absorber system applied to the superheating section of a concentrating solar belt. Background technique [0002] Solar energy and wind energy are important components of renewable energy. In recent years, in order to solve environmental pollution problems and reduce fossil energy consumption, renewable energy alternatives centered on solar energy and wind energy are emerging all over the world. my country is a country rich in solar and wind resources. Statistics show that by the end of 2018, my country's cumulative installed photovoltaic capacity was 170 million kilowatts (9% of installed capacity), and 184 million kilowatts of wind power (9.7% of installed capacity). The proportion of wind energy and solar energy in my country's energy structure is gradually increasing. [0003] Different from photovoltaic power ...
