VORTEX INDUCTION BLOCK IN THE GAS VENTILATION DUCT

摘要

PURPOSE: A vortex guiding device for a gas discharge pipe is provided to increase exhaust volume for unit hour and to increase gas density per the unit area of an exhaust duct by converting linear gas flow to a vortex shape with first and second vortex guides. CONSTITUTION: A vortex guiding device for a gas discharge pipe comprises a first vortex guide(310) and a second vortex guide(320). The first vortex guide has a cylindrical shape of which inside is vacant. The second vortex is mounted inside the first vortex. Multiple first vortex guide blades are installed on the top of the first vortex guide and are arranged toward a central shaft of the first vortex guide.
