Abstract

This invention relates to the technical field of water electrolysis hydrogen production equipment, providing a T-type coupled gas-liquid separation and condensation integrated device and its working process for water electrolysis hydrogen production. The device includes a housing comprising a horizontal separation section, a vertical condensation section, and a liquid collection section. The liquid collection section and the vertical condensation section are located on the same vertical plane, with the vertical condensation section positioned above the liquid collection section. The horizontal separation section, vertical condensation section, and liquid collection section are connected and together form a T-shaped structure. A gas deflection channel is formed at the intersection of the vertical condensation section and the horizontal separation section, causing the gas after initial liquid removal to change from horizontal flow to vertical upward flow. The deflection channel forms a flow guiding transition structure to prevent secondary entrainment caused by eddies in the gas flow. This invention employs a three-stage synergistic purification process, achieving excellent gas-liquid separation and demisting efficiency. It utilizes a three-stage synergistic treatment mechanism of gas-liquid cyclone initial separation + deep condensation dehydration + wire mesh demisting, combined with a strong swirling flow field to enhance droplet detachment and a flow equalization plate to optimize airflow distribution, effectively removing electrolyte droplets and water vapor entrained in the gas.
