Description

Technical Field

[0001] The utility model relates to the technical field of smelting tail gas treatment equipment, in particular to a tail gas treatment mechanism for high-titanium slag smelting. Background Art

[0002] High-titanium slag smelting refers to the smelting of titanium concentrate and the purification of titanium slag. The high-titanium slag smelting operation is usually carried out in a corresponding high-titanium slag smelting furnace. When using a high-titanium slag smelting furnace for smelting operations, gases that are polluting to the environment are usually discharged. In order to achieve the effect of environmentally friendly production, the discharged exhaust gas is usually treated. Conventional exhaust gas treatment operations generally directly pass the exhaust gas into the corresponding waste gas spray tower for treatment.

[0003] However, when the exhaust gas spray tower is used to directly treat the tail gas, since the newly discharged tail gas contains unburned substances, such as carbon monoxide, impurities and debris, it is difficult to achieve a good treatment effect by directly using the exhaust gas spray tower. It cannot ensure that the tail gas is fully burned, which affects the treatment effect of the tail gas and brings inconvenience to the user. In view of this, we proposed a tail gas treatment mechanism for high titanium slag smelting. Utility Model Content
