Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a device for secondary combustion and rapid cooling of smelting flue gas. Background Technology

[0002] Industrial processes such as metal smelting generate large amounts of flue gas containing various pollutants. Among these, unburned substances and highly toxic organic pollutants such as dioxins, if directly emitted without effective treatment, will cause significant harm to the environment and human health.

[0003] However, existing rapid cooling treatment devices lack efficient filtration capabilities, which means that the rapid cooling treatment devices cannot remove dust from the flue gas when cooling it, thus reducing the efficiency of the rapid cooling treatment devices. To address this, we propose a secondary combustion and rapid cooling treatment device for smelting flue gas. Utility Model Content
