Description

Technical Field

[0001] This utility model relates to the field of collection device technology, and more specifically to a zinc oxide flue gas collection device. Background Technology

[0002] Secondary zinc oxide flue gas is a complex flue gas produced during the non-ferrous metal smelting process, especially in the zinc smelting process. This flue gas mainly comes from the pyrometallurgical zinc smelting and hydrometallurgical zinc smelting processes in the zinc smelting industry. During the smelting process, zinc-containing materials react with reducing agents at high temperatures to generate zinc vapor. The zinc vapor then reacts with oxygen in the air to generate zinc oxide dust. This dust is discharged along with the flue gas, thus forming secondary zinc oxide flue gas.

[0003] The shortcomings of existing zinc oxide flue gas collection devices:

[0004] Firstly, zinc oxide flue gas contains a large amount of heavy metals. If zinc oxide flue gas is allowed to be emitted into the atmosphere, it will lead to reduced atmospheric visibility and environmental problems such as acid rain. Therefore, flue gas collection devices are needed to collect these waste gases. However, since the flue gas contains impurities such as zinc oxide particles and ammonium salt particles, it is necessary to install a filter screen on the surface of the collection device. But the filter screen will gradually be blocked by zinc oxide particles, ammonium salt particles and other impurities, affecting the collection effect.

[0005] Secondly, after these exhaust gases are collected, they are purified inside the device before being discharged. However, the purification mechanism will experience a decline in performance after long-term filtration, making it unable to meet the current exhaust gas treatment needs. Utility Model Content
