Thermal chemical heat storage material performance detection device

Abstract

The invention relates to the technical field of thermal chemical heat storage material performance characterization, in particular to a thermal chemical heat storage material performance detection device, which comprises a heating furnace, a plurality of stages of heating assemblies are arranged in an inner cavity of the heating furnace at intervals along the axial direction, and the plurality of stages of heating assemblies are slidably mounted in the inner cavity of the heating furnace; the pressure-adjustable reactor penetrates through the heating furnace in the sliding direction of the heating assembly, an inner cavity of the reactor is sealed, and a sample filler is arranged in the inner cavity of the reactor; the material balance is mounted on the reactor and is connected with the sample filling device in a matched manner, so that the thermal performance measurement of the thermochemical heat storage material under the condition of variable temperature and pressure is realized; by continuously changing the heating assembly corresponding to the sample filling device, the heat storage and heat release circular reaction conditions of the thermochemical heat storage material are rapidly switched, and the container does not need to be reheated after being cooled during reaction overshoot, so that the waiting time during the heat storage and heat release circular reaction test of the thermochemical heat storage material is greatly shortened, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of performance characterization of thermochemical heat storage materials, in particular to a performance detection device for thermochemical heat storage materials. Background technique [0002] Depending on the way of heat storage, heat storage materials can be divided into three categories: sensible heat, latent heat, and thermochemical heat storage materials; the selection and application of materials are different, and each has its own characteristics: thermochemical heat storage materials rely on reversible adsorption / desorption Attachment process or chemical reaction process to realize thermal energy storage and utilization, high energy storage density, has become one of the hotspots in the research of heat storage materials. Thermochemical heat storage materials store and release energy by changing the bond energy of material formation and dissociation during the chemical reaction process. The shape a...
