Fused salt heat storage system for solving problem of wind curtailment

Abstract

The invention discloses a fused salt heat storage system for solving the problem of wind curtailment. The fused salt heat storage system for solving the problem of wind curtailment comprises high-temperature and low-temperature fused salt tanks, high-temperature and low-temperature fused salt distributing tubes, high-temperature and low-temperature fused salt pumps, an electric heater, a fused salt-steam generating device and the like, wherein the high-temperature and low-temperature fused salt distributing tubes are respectively arranged in the two tanks; the high-temperature and low-temperature fused salt pumps are used for driving fused salt; the electric heater is used for heating the fused salt; the fused salt-steam generating device is used for generating steam. The electric heater, the fused salt-steam generating device, the cold and hot fused salt pumps and the like are arranged on a heat exchange platform between the fused salt tanks; the heat exchange platform is higher than the cold and hot fused salt tanks in general design, a fused salt tube has certain downward inclination in the flow direction, so that the fused salt in the tubes, the heater and a heat exchanger is emptied when the fused salt system stops running, the fused salt is prevented from being solidified, and the safety of the fused salt system is guaranteed.

Description

technical field [0001] The invention relates to a molten salt heat storage system to deal with the problem of abandoned wind, and belongs to the technical field of renewable energy utilization. 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 energy resources and wind power resources. In the past ten years, the utilization of solar energy and wind energy has made great progress in our country. Statistics show that by the end of 2015, my country's cumulative installed capacity of photovoltaics was 41.58 million, and the cumulative installed capacity of wind power was 128.3 million. The proportion of wind energy and solar energy in my country's energy structure is gradually inc...
