Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a combined ion deodorization device. Background Technology

[0002] Acidic and alkaline waste gases refer to acidic or alkaline waste gases emitted from industrial production and daily life. They mainly originate from various industries such as chemical engineering, metallurgy, power generation, electronic components, electroplating, textiles (chemical fibers), food processing, and machinery manufacturing. Unlike organic waste gases, acidic and alkaline waste gases do not contain organic matter; instead, they are mainly composed of acidic and alkaline substances. Due to their unique chemical properties, acidic and alkaline waste gases are prone to forming acid rain in the atmosphere, posing a serious threat to the environment. Therefore, the treatment of acidic and alkaline waste gases is of paramount importance.

[0003] Most existing treatments for acidic and alkaline waste gases involve alkaline scrubbing towers. When waste gas containing acidic or alkaline pollutants enters the tower, it flows upwards to the filter bed and reacts fully with the alkaline neutralizing liquid sprayed from the nozzles. During this process, the acidic pollutants react chemically with the alkaline solution, being neutralized and converted into salts and water. Simultaneously, some soluble substances in the waste gas are absorbed and dissolved. However, the scrubbing liquid in existing alkaline scrubbing towers is mostly continuously recycled. After multiple uses, the scrubbing liquid not only carries impurities that can clog the water pump, but also lacks effective monitoring of its concentration. Utility Model Content
