The wet oil mist purification tower uses the gas-liquid mass transfer theory. In the process of exhaust gas passing through the tower body, a series of irreversible chemical reactions such as sulfur dioxide, nitrogen oxides and oil mist particles undergo with the absorption liquid to generate new salt substances and The physical action captures the oil mist particles into the circulating liquid to achieve the purpose of purification.
The wet oil mist purification tower innovatively developed by our company is based on the original one and has made certain improvements. On the basis of precise calculations, numerical simulation methods are introduced. At the air inlet of the tower, the exhaust gas to be purified is rushed at a certain speed. Inside the tower, the impact port is close to the liquid level. During the impact, a large number of droplets are aroused. The generated droplets are violently mixed with the rising airflow, and then rise together with the airflow to play a preliminary purification role.
1. Safety: The wet purification tower has its own water seal function, and the overall stability and safety of the purification system are high;
2. Easy operation: less equipment maintenance workload, low failure rate, and moderate operating cost;
3. Preliminary purification of VOCs: The wet purification tower has a certain dissolution and absorption effect on water-soluble substances in the exhaust gas, and can remove large particulate matter and macromolecular water-soluble organic matter in the exhaust gas.
It is mainly used in pre-treatment processes such as industrial oil fume and dust generated by petrochemical, packaging and printing, food processing, aluminum alloy die-casting and other industries.
