Abstract

The invention provides an efficient moisture absorption-thermal chemical reaction single-stage thermode driven by low-grade heat energy. According to the efficient moisture absorption-thermal chemical reaction single-stage thermode driven by low-grade heat energy, a reaction bed valve block is connected with a left reaction bed and a right reaction bed, a condenser valve block is connected with a left condenser and a right condenser, an evaporator valve block is connected with a left evaporator and a right evaporator, the left reaction bed, the left condenser and the left evaporator are connected in sequence, and the right reaction bed, the right condenser and the right evaporator are connected in sequence. According to the efficient moisture absorption-thermal chemical reaction single-stage thermode driven by low-grade heat energy, the circulating moisture absorption capacity is greatly improved, and thus the density of the energy flow is increased; meanwhile, the quality of low-temperature fluid is improved, and high-temperature fluid is obtained. When the temperature of a heat source is 95 DEG C and the condensing temperature is 15 DEG C, the temperature of the heat source can be increased to 125 DEG C from 70 DEG C, and the energy density of a system can reach 1.86kWh / kg; internal energy storage is achieved, moisture-absorption salt is separated from refrigerating fluid during energy storage, and no loss can be caused; when the temperature of the low-temperature fluid needs to rise, a user just needs to enable the moisture-absorption salt to be in contact with with the refrigerating fluid, and thus the high-temperature fluid can be obtained.

Description

technical field [0001] The invention relates to the technical field of chloride salt / expanded graphite-water single-stage temperature changer, in particular to a low-grade thermal energy driven high-efficiency moisture absorption-thermochemical reaction single-stage temperature changer. Background technique [0002] my country has huge potential in the utilization of low-grade heat energy: my country's overall energy utilization efficiency is about 10 percentage points lower than developed countries, and high energy-consuming enterprises such as metallurgy, cement, and ceramics have a large amount of low-temperature waste heat (80-200°C) that has not been utilized. If these energies are fully utilized, my country's fossil energy consumption and greenhouse gas emissions can be greatly reduced, which is also in line with my country's strategic requirements for sustainable development. Therefore, China's National Energy Science and Technology "Twelfth Five-Year Plan" will reduc...
