Dioxins and furans are halogenated aromatic hydrocarbons, a class of substances with similar chemical structures. Most of them are by-products unintentionally generated during chemical manufacturing or insufficient combustion. Dioxins easily adhere to dust particles.
Common sources include bleaching processes used in pulp and paper production, manufacturing of weed and pest control products, as well as solid waste incineration, power generation, and metal smelting and refining.

ZTW Catalytic Filtration System

Low temperature and high-efficiency nanocatalytic filtration system based on ceramic catalytic filter tubes.
Purification performance: removal efficiency ≥ 99%, completely replacing activated carbon.
Applicable temperature range: 200-260 ℃.

Ceramic catalytic filter tubes using low-temperature catalysts are highly suitable for efficient removal of dioxins and can completely replace activated carbon. Activated carbon only transfers dioxins into fly ash; The fly ash contaminated with dioxins needs further treatment. The catalytic filtration system can thoroughly and efficiently remove dioxins.

The optimal upper temperature limit for removing dioxins is 260 degrees Celsius. Beyond this temperature, if there are components such as chlorine, fluorine, and other halides in the flue gas, these components will promote the reformation of dioxins. Even if these components have been mostly removed upstream by injecting dry adsorbents, permanent dioxin destruction will occur at higher temperatures.
