The method for regulating and controlling the adsorption and desorption process through radiation refrigeration and solar heating comprises the steps of coupling a radiation refrigeration coating with an adsorbent, and reducing the temperature of the adsorbent below the radiation refrigeration coating in a mode of reflecting solar radiation and radiation heat when the radiation refrigeration coating is exposed to sunlight above the adsorbent so as to carry out a gas adsorption process; when the radiation refrigeration coating is arranged below the adsorbent, the adsorbent is exposed to sunlight to obtain energy from solar radiation, the temperature of the adsorbent is raised, and therefore a gas desorption process is carried out.
Description
Technical Field
The invention relates to a method for regulating an adsorption and desorption process, in particular to a method for regulating an adsorption and desorption process through radiation refrigeration and solar heating.
Background
The adsorption separation technology is an important way for gas separation in the current industrial process due to mild operation conditions, simple process and low cost. Temperature swing adsorption and pressure swing adsorption techniques are widely used, which achieve adsorption and desorption of gases by varying temperature and pressure, respectively. The principle of temperature swing adsorption is that under the condition of keeping pressure unchanged, low-temperature adsorption is carried out, and the temperature is raised for desorption. The principle of pressure swing adsorption is that under the premise of keeping the temperature unchanged, high-pressure adsorption and low-pressure or vacuum-pumping desorption are carried out. However, the former technique requires an additional heating process, and the latter technique requires an additional pressurization and depressurization operation, which is a major source of energy consumption in the current adsorption separation technique. Therefore, the problem of how to reduce the energy consumption of the conventional separation technology is receiving wide attention.
Solar radiation, i.e. the sun radiates energy to the earth in the form of electromagnetic waves, and the generated solar energy is a renewable clean energy source. The application of radiation refrigeration technology to realize solar radiation cooling and the application of solar heating to realize object heating are two fields which have wider application of solar radiation energy. Considering the temperature reduction and temperature rise processes required by the temperature swing adsorption, if solar radiation can be used for temperature modulation in the temperature swing adsorption process, the cost of the temperature swing adsorption process can be expected to be greatly reduced. However, there is no report in the field of how to effectively use solar radiation in gas absorption and desorption processes.

According to examples 1-3 and 4-6, the cooling effects of different radiation refrigeration coatings on the adsorbent under solar radiation are not greatly different, and the temperature difference of the desorption section of the same adsorbent under the same intensity illumination is not large.
The temperature of each adsorbent in the adsorption section is obtained according to the table 1, 3, 4, 7-24, and the temperatures of the adsorption sections are relatively close under the same radiation refrigeration coating. The desorption temperature mainly depends on the properties of various samples, such as color, dark-color adsorbents are obviously better than light-color adsorbents, and the light absorption performance of the materials, such as the color of the materials in special cases 7 and 8 is similar to that of part of special cases, but the temperature rise under solar radiation is obvious.
The results of the influence of solar radiation on the temperatures of the adsorption section and the desorption section shown in the examples 1-24 in the table 1 can be combined, so that the method is applicable to various adsorbent materials and various radiation refrigeration coatings, and the technology has better universality. Under the condition of not needing any external energy consumption, the temperature of the adsorption section and the desorption section can be regulated and controlled only by solar energy.
