Abstract

The invention belongs to the technical field of combined heat and power generation for heating and relates to a heat storage plate type heat exchanger. 13-20 heat storage type heat exchange plates arelocated and closely arranged between a fixed compression plate and a movable compression plate through guide rods. Each sealing pad is arranged between the corresponding two adjacent heat storage type heat exchange plates. Every two adjacent sealing pads are placed in opposite directions. The heat storage type heat exchange plates are tightly pressed through compression threaded rods, so that theheat storage plate type heat exchanger is formed. Each heat storage type heat exchange plate is provided with a plate type cavity, wherein a phase change heat storage material is encapsulated in eachplate type cavity. By means of phase change latent heat of the phase change material, the plate type heat exchanger has the heat storage capability. When a combined heat and power generation unit participates into load peak shaving of an electric network, the phase change heat storage material mainly stores or releases heat in the form of the phase change latent heat, and the heat storage plate type heat exchanger can achieve the effect of heating load adjustment. By means of the heat storage plate type heat exchanger, the load peak shaving capability of the combined heat and power generationunit during the heating period is enhanced; the grid connection space of new energy power generation is expanded; and the heat storage plate type heat exchanger is suitable for participating into thecombined heat and power generation unit for electrical load peak shaving.

Description

technical field [0001] The invention belongs to the technical field of cogeneration heat supply, and in particular relates to a heat storage plate heat exchanger. Background technique [0002] According to my country's electric power development blueprint, by 2020 my country's renewable energy power generation will account for more than 15%. Since cogeneration heating units generally adopt the heat-fixed power operation mode in the heating season, the peak-shaving capability of power load is poor, which limits the grid connection of new energy generation with load fluctuations such as wind energy and solar energy, resulting in serious wind and energy curtailment. Therefore, it is one of the key issues facing the field of combined heat and power to explore effective technical approaches to improve the power load peak-shaving capacity of cogeneration units in the heating season and to leave more space for new energy power generation to be connected to the grid. [0003] The p...
