Abstract

The invention discloses a heat exchange system. The heat exchange system comprises a first high-temperature heat storage medium conveying pipeline, a first low-temperature heat storage medium conveying pipeline, a second high-temperature heat storage medium conveying pipeline, a preheater, an evaporator, a superheater, a water feeding device and a steam turbine. Compared with the prior art, the heat exchange system has the innovative points that by arranging the second high-temperature heat storage medium conveying pipeline, when a heat storage medium coming from the superheater is cooled after being subjected to heat exchange and consequently cannot meet the load demand of the heat exchange system, a high-temperature heat storage medium can be supplemented into the evaporator through the second high-temperature heat storage medium conveying pipeline, the temperature of the heat storage medium entering the evaporator is increased, and accordingly, the purpose of improving load of the heat exchange system is achieved.

Description

technical field

[0001] The invention relates to the field of solar thermal power generation, in particular to a heat exchange system. Background technique

[0002] With the continuous consumption of fossil fuels, the problem of energy depletion is becoming more and more serious. In addition, the massive consumption of fossil energy is constantly destroying the living environment of human beings and seriously threatening the survival and safety of human beings. As a renewable green energy, solar energy has the characteristics of "inexhaustible and inexhaustible". As a way of solar energy utilization, solar thermal power generation can ensure stable power output and has the ability of peak shift regulation, so it has a wide application prospect.

[0003] At present, the most widely used solar thermal power generation technologies mainly include tower technology and trough technology, and the medium used for heat absorption is mainly molten salt and heat transfer oil. Howeve...
