Technical Field
The invention belongs to the technical field of solid-state heat storage, and particularly relates to a U-shaped ventilation structure on a solid-state heat storage device.
Background
The solid heat storage device is a novel electric heat storage system, and utilizes valley electricity, abandoned wind, abandoned light and abandoned water electric energy to convert effective energy into heat energy to be stored in a solid heat storage material and continuously released to a heating system or a hot water system, so that the solid heat storage device is a novel clean heat source.
During the operation of the device, the heat storage wall is heated and cooled within a certain period in the heat storage and release process. At present, the through-flow structure of the device is linear and belongs to a forward and backward discharging type, and the heat exchanger, the fan and the heat storage wall are arranged in an up-and-down stacked mode. When the device releases heat for the first time, cold air enters the heat storage wall from the air inlet at the front end, the solid heat storage material heats the cold air, the cold air is changed into hot air after being gradually heated, the cold air enters the steam-water heat exchanger from the air outlet at the rear end to release heat, the temperature difference between the air and the front end and the rear end of the heat storage wall is gradually reduced, the heat transfer and exchange effect is reduced, a temperature gradient exists longitudinally in the heat storage wall after the heat is released for the first time, and the. After the heat is released once, the device stores heat again, the area with higher temperature of the heat storage wall can quickly reach the set heating temperature, the device protection system can automatically stop heat storage work, and the area with lower temperature of the heat storage wall can not continuously store heat, so that the heat storage capacity of the device is reduced.
Meanwhile, the heat storage wall is in a state of non-uniform temperature field for a long time, and certain influence is brought to the overall reliability and the service life of the solid heat storage material.
