Abstract
This invention provides a waste heat recovery device for a pressure swing adsorption (PSA) hydrogen purification equipment, including a purification conveying pipe, a heat collection tube inside the purification conveying pipe, a separation plate inside the heat collection tube, and a feeding trough inside the separation plate. The number of separation plates is set to multiple. This invention is rationally designed. By placing the heat collection tube inside the purification conveying pipe used for transporting hydrogen, the hydrogen can directly contact the heat collection tube. Simultaneously, the liquid inside the heat collection tube flows in a ring, allowing more hydrogen to come into contact with the liquid, increasing the heat absorption range. Furthermore, the heat-conducting strips can transfer heat from the outside to the inside of the liquid, improving the heat adsorption rate.
