Embodiment Construction

[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0022] The method for heat storage and utilization of gas-solidification chemical reaction in this embodiment includes the following specific steps:

[0023] The first step, heat storage: use the waste water (temperature at 90°C-100°C) generated at the factory to treat the solid material (the composition is CaCl 2 .8NH 3 and expanded graphite) heated to decompose it into a reactive solid (the composition is CaCl 2 .2NH 3 and expanded graphite) and ammonia, the ammonia is condensed;

[0024] The second step, heat storage: store the decomposed reaction solids and am...

The invention increases availability ratio of energy, which is pollution-free, simple in apparatus structure.

Description

technical field [0001] The invention relates to a method and a device in the field of energy technology, in particular to a method and a device for gas-solidification chemical reaction heat storage and utilization. Background technique [0002] Since the outbreak of the oil crisis, energy issues have attracted more and more attention from the world. Since the supply and utilization of energy are not always consistent in quantity, time, and space, how to store surplus energy and re-release it at an appropriate time and place has become one of the energy research issues. For example, in large factories such as power plants and chemical plants, a large amount of waste heat is generated, including waste gas and waste water; devices such as boilers and engines also generate waste heat. If the waste heat is stored and then exported at a suitable time and place, the efficiency of energy utilization will be greatly improved. The heat storage methods currently used are mainly sensi...
