| description | Regeneration is among the key processes in a liquid desiccant and its efficiency directly affects the entire performance. A device is proposed in the studyin which low-temperature waste heat (40–80 ℃) from power plant is transferred through a heat pipefor solution regeneration. The regeneration experiment is conductedwith a 30–45% calcium chloride solution and water separation rateis taken as the indicator of the solution regeneration performance. The results show that low temperature heat source of 40–80 ℃ with heat pipe heat transfer can realize high-efficiency regeneration of calcium chloride solution in a vacuum environment. The equilibrium pressure in the vacuum regenerator is mainly limited by the cooling water temperature when the regeneration solution has a low flow rate. The pressure decreases with a decrease in temperature and the separation rate increases with an increase in the heat source temperature. Particularly when the heat source temperature increases from 60 to 70 ℃, the water separation sharply increases. As the concentration increases, the primary separation rate of the water decreases; the water separation rate can be significantly improved by controlling the falling flow rate because the calcium chloride solution has a special molecular structure of water absorption. |
