Air Bubble 및 UV램프를 적용한 스크러버 복합 악취 저감 시스템 개발

초록

In this study developed a scrubber-based hybrid odor reduction system to effectively mitigate complex odors commonly found in industrial sites and analyzed its performance through experimental methods. Traditional water-scrubbing systems have shown limitations, so this research combined air bubble technology with UV-C LED lamps to create a system capable of achieving both physical and photochemical odor removal effects. The developed system integrates an air bubble injection unit into a vertical packed tower scrubber to enhance the gas-liquid contact area and promote gas diffusion through bubbles. A UV-C module was installed at the upper section to decompose odor compounds via photolysis. Additionally, a chemical dosing and mixing unit, along with a venturi-based airflow structure, was incorporated to improve mixing and reaction efficiency. Experiments were conducted using actual industrial exhaust gases containing ammonia (NH3), total volatile organic compounds (TVOC), and carbon dioxide (CO2). Removal efficiencies were evaluated under various operating conditions, including the presence or absence of UV irradiation, variations in air bubble frequency, and chemical concentration. The system was tested under three modes: UV only, air bubble only, and a combined operation. Results indicated that the combined use of UV and air bubbles achieved a maximum TVOC removal efficiency of up to 87%. Higher air bubble frequencies also showed an increasing trend in removal efficiency alongside a rise in differential pressure. The system was designed in a modular format to accommodate limited installation spaces, making it highly suitable for small- and medium-sized manufacturing facilities frequently affected by odor complaints. The research outcomes demonstrated the system’s practical applicability and cost-effectiveness, offering a promising technological foundation for creating eco-friendly industrial environments in the future.
