Application field and working principle of spray tower

Application field:

1. Waste gas purification: Spray tower is an important tool for industrial waste gas purification. By making the exhaust gas fully in contact with water, it can efficiently remove harmful substances in the exhaust gas, such as sulfur dioxide, nitrogen oxides and particulate matter, etc., providing a clean emission environment for industrial production.

2. Wastewater treatment: Spray tower is also suitable for wastewater treatment. After the washing function of the spray tower, the waste water can remove the harmful substances such as heavy metals and organic matter, and realize the purification of the waste water and discharge up to the standard.

3. Gas purification and recovery: The spray tower can not only purify gas, but also realize the recycling of waste gas. Through a specific chemical reaction, it can remove harmful substances from the gas, while recovering useful gases such as nitrogen and oxygen.

How it works:

The core working mechanism of the spray tower is to use the contact between water and exhaust gas to remove harmful substances in the exhaust gas. When the exhaust gas enters the spray tower, it is first washed and cooled by the water flow, reducing the temperature and initially removing some particles. Then, the exhaust gas and the dissolved substances in the water undergo a chemical reaction, these dissolved substances may be alkaline or other substances that can neutralize, REDOX and other reactions with harmful substances in the exhaust gas. These reactions convert harmful substances in the exhaust gas into harmless or low-toxic substances, thus achieving the purification of the exhaust gas. After the treatment of the spray tower, the exhaust gas needs to go through subsequent treatment steps such as filtration and dust removal before it can be safely discharged into the atmosphere.

In summary, the spray tower is widely used in industrial waste gas treatment and waste water treatment and other fields, its working principle is based on the contact and chemical reaction between water and waste gas, to achieve the purification of waste gas and the removal of harmful substances.
