Gas Inlet Dry reaction tower

A dry reaction tower, also known as a dry scrubber or dry absorption tower, is an air pollution control device used to remove pollutants and acidic gases from industrial gas streams without the use of liquid sprays or water. It is commonly employed in industries where wet scrubbing may not be suitable or feasible, such as in high-temperature applications or when water availability is limited.

The operation of a dry reaction tower typically involves the following steps:

Gas Inlet: The gas stream containing pollutants and acidic gases enters the dry reaction tower through an inlet. These pollutants can include sulfur dioxide (SO2), hydrogen chloride (HCl), hydrogen fluoride (HF), or other acid gases.

Sorbent Injection: Inside the dry reaction tower, a sorbent material is injected into the gas stream. The sorbent can be in the form of a dry powder or granules and is specifically chosen to react chemically with the pollutants present in the gas stream.

Chemical Reaction: As the gas stream passes through the dry reaction tower, the sorbent material reacts with the acidic gases and pollutants. This chemical reaction typically involves neutralization or absorption of the acid gases by the sorbent material.

Pollutant Capture: The sorbent material, now laden with the captured pollutants, continues to move through the dry reaction tower. The captured pollutants adhere to the surface of the sorbent particles or are chemically bound to them.

The flue gas at 200℃ enters the dry reaction device, and the flue gas enters the dry acid removal and dioxin absorption device for tail gas purification. There is a storage tank for slaked lime and activated carbon at the connecting flue in front of the bag. The materials are stored in a star-shaped It is transported by the ash discharge valve and enters the connecting flue. The Roots blower blows up the material and reacts with the incineration exhaust gas to further purify the exhaust gas. Spray in slaked lime and activated carbon to remove acidic components such as dioxins, HCL, NOx and a small amount of heavy metals in the absorbed flue gas.
