Technical Field

Background
In recent years, the carbon dioxide drying method mainly comprises surface cooler cooling and drying and solution drying, wherein the principle of the surface cooler cooling and drying is that cooling water and carbon dioxide are subjected to indirect heat exchange, the gas temperature is reduced to be below the dew point temperature, and water is condensed and separated out so as to achieve the effects of cooling and dehumidifying; the principle of solution drying is to utilize the partial pressure difference between the air on the surface of the brine and the water vapor of the carbon dioxide gas to transfer the water in the carbon dioxide into the brine so as to achieve the drying effect. Compared with the surface cooler for cooling and drying, the solution drying has larger heat and mass transfer area, higher drying efficiency and better effect.
However, when the drying load is larger, the temperature change of the brine in the drying process is larger, the heat exchange quantity of each area in the filler is unevenly distributed, and the dehumidification efficiency is lower. In addition, due to the change of the temperature of the brine, the temperature and the moisture content of the carbon dioxide outlet are not uniformly distributed, the temperature and the humidity of the carbon dioxide close to the brine inlet are low, and the temperature and the humidity of the carbon dioxide close to the brine outlet are obviously higher.
In order to solve the problem of uneven temperature and humidity distribution of gas to be dried in a dryer and lower drying efficiency, a closed cycle drying system (CN 110986486B) based on two-stage solution dehumidification proposes a mode of adopting a combined synergistic effect of a first-stage solution dehumidification-regeneration circulating system and a second-stage solution dehumidification-regeneration circulating system, firstly, carrying out first-stage dehumidification on a high-temperature and high-humidity drying medium by adopting a solution with higher temperature and lower concentration, and then carrying out second-stage dehumidification by adopting a solution with lower temperature and higher concentration after forming a medium-temperature and medium-humidity drying medium.
In order to simplify the flow while optimizing the drying efficiency, the drying efficiency is improved by arranging a first solution isolation layer and a second solution isolation layer in a solution dehumidifier unit and an air conditioning system (CN 108413498A) with the same, and arranging a hood structure to avoid solution blending. However, the solution pump is required to be additionally added to pump the solution to each area, the occupied area of the device is large, and the equipment cost is high.
