The deodorization system adopts a standardized combined process of collection – primary spray – deep purification – high-altitude emission. It conducts sealed and centralized collection of odor gas generated from fermentation tanks. After multi-stage spray degradation and advanced oxidation treatment, the qualified clean gas is discharged at high altitude, achieving efficient deodorization while meeting environmental protection standards.
The odor gas generated by the fermentation tank is first collected centrally through exhaust merging pipelines, gathering scattered exhaust gas into a unified airflow to facilitate subsequent centralized treatment.
Primary Spray Treatment
The spray liquid absorbs harmful substances in the exhaust gas. With a large centralized spray contact area, it can rapidly adsorb pollutants in the flue gas. The spraying process also reduces exhaust gas temperature and avoids damage to subsequent treatment equipment caused by high temperature and high humidity.
Secondary Pickling Treatment
It efficiently removes alkaline pollutants. The automatic dosing system rationally distributes acid consumption, and converts alkaline pollutants into soluble salts through chemical reactions with high purification efficiency.
Tertiary Saturated Ozonated Water Oxidation Treatment
This technology utilizes the strong oxidizing property of ozone (O₃). Ozone is dissolved in water to form saturated ozonated water, which fully contacts and reacts with odor components in the exhaust gas. It destroys the molecular structure of odorous substances and decomposes them into odorless or low-odor small-molecule compounds, ultimately converting them into harmless substances such as carbon dioxide and water. It not only effectively eliminates odor components but also reduces organic matter content in exhaust gas to ensure discharge up to standard.
The clean gas after the above processes is discharged in a organized manner through the chimney under the power of the fan, fully complying with the emission standards for ammonia and odor specified in GB 14554.
