Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting tail gas recovery equipment, in particular to a tail gas recovery equipment for non-ferrous metal smelting which is easy to clean. Background Art

[0002] Non-ferrous metal smelting refers to the smelting process of metals such as copper, aluminum, zinc, and nickel. Non-ferrous metals are usually metals with a certain electrical conductivity and thermal conductivity. They are usually used to manufacture wires, cables, electronic components, building materials, etc. The main steps of non-ferrous metal smelting include ore dressing, ore smelting, refining and finished product manufacturing. During the smelting process, high-temperature smelting furnaces and chemical solvents are required to extract useful metals from the ore, and then refine and alloy them to finally obtain metal products that meet the requirements.

[0003] The tail gas generated during the metal smelting process mainly includes flue gas and waste gas. These tail gases contain a large amount of harmful substances, such as sulfur dioxide, nitrogen oxides, heavy metals, etc., which cause serious pollution to the environment. They can be treated through dust removal, desulfurization, denitrification and other technologies to reduce pollution to the environment. In the existing technology, the tail gas generated during the metal smelting process is effectively recycled and utilized, which can not only reduce pollution to the environment, but also reduce production costs and achieve sustainable development. However, some existing waste gas recovery devices, after long-term use, will cause more solid objects to adhere to the inside, which will easily cause blockage of the filtering waste gas, thereby reducing the use effect of the device. Moreover, when the harmful substances in the tail gas are absorbed by the solvent, the harmful substances in the solution are easy to reach a saturated state, resulting in a decrease in the effect of continuous use. Therefore, it is urgent to solve the above problems. Utility Model Content
