The Zhongtong brand Ozone Tail Gas Destructor is a method and device for treating ozone tail gas, commonly used in the wastewater treatment field. The treatment method employs a Zhongtong proprietary ozone catalyst, which is activated by heating in conjunction with the tail gas destruction unit. The bottom features a tail gas inlet, while the top is equipped with a tail gas destruction outlet.

Introduction to the working principle of an ozone tail gas destructor:

Tail gas from the ozonated contact pond still contains a certain amount of ozone. If released directly into the atmosphere, it would cause air pollution. The environmental emission standard for ozone tail gas is 0.3 mg/L. Common treatment methods for ozone tail gas include chemical and electrically heated decomposition methods. The chemical method typically involves catalyst and activated carbon absorption. The catalyst method uses manganese dioxide as the base and filling material as a catalyst, which can catalytically decompose ozone. This method has low equipment investment and operating energy consumption, but its drawbacks include the need for moisture removal before entering the processor; poor safety and stability; and the need for regular replacement of the catalyst. The activated carbon absorption method utilizes the surface of the porous carrier carbon to absorb and decompose ozone, as well as some ozone reacting directly with activated carbon to produce CO2 and CO. The disadvantage of this method is that heat is generated during the absorption and oxidation process of ozone, creating unstable ozonated products, which increases the risk of combustion and explosion, especially when nitrogen oxides are present. This method should be used with caution in practical production.
