Abstract
A deodorizer is a device that removes odors by chemical reactions by injecting odor gas into a reactor filled with chemical liquid. The odor gas injected through the odor gas injection pipe rises through a perforated plate installed in two stages of a cross-shaped structure for slowing the rate of rise of the gas, and the odor gas is removed by a gas-liquid chemical reaction. To uniformly inject the odor gas into the reactor and to reduce the pressure loss in the reactor, instead of a single nozzle installed at the end of a pipe currently used, a nozzle in which outlet holes were uniformly arranged at equal intervals was proposed. In order to confirm the case where the odor gas was most uniformly distributed in the reactor, the volume fraction of the gas-liquid and flow characteristics were obtained through computational fluid dynamics analysis using VOF model for different size and number of holes.
