Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and in particular relates to a complex fume washing and purification device for copper smelting. Background Art

[0002] Copper smelting is an important metallurgical technology. In the electric power industry, copper is a good conductive material with good electrical conductivity. In the construction industry, copper has good corrosion resistance and structural strength. Combining the above properties, copper is widely used in various fields. When copper is produced and smelted, flue gas will be discharged. The long emission time will cause dirt inside the equipment. Therefore, a complex flue gas washing and purification device for copper smelting is proposed.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN214552066U, which discloses a copper smelting complex flue gas washing and purification device. The arrangement of the copper smelting complex flue gas washing and purification device includes a primary power wave, a secondary power wave, a packing tower, a liquid collecting hopper and a sedimentation tank. The lower ends of the primary power wave, the secondary power wave and the packing tower are all connected with a longitudinal circulation pump, and a doser is installed at one side of the longitudinal circulation pump. The interiors of the primary power wave, the secondary power wave and the packing tower are all filled with washing liquid. The upper air outlet of the primary power wave and one side of the secondary power wave are connected with a flue gas pipe, and the upper air outlet of the secondary power wave and one side of the packing tower are connected with a flue gas pipe. The utility model significantly reduces flue gas impurities through three washings of the primary power wave, the secondary power wave and the packing tower with washing liquid, and circulates the washing liquid through the longitudinal circulation pump and the transverse circulation pump, which not only further optimizes the flue gas impurity removal effect, but also improves the use efficiency of the impurity removal agent and reduces the production cost.

[0004] During the use of the existing copper smelting complex flue gas washing and purification equipment, due to the complex internal composition of copper, waste gas will be formed during the smelting process of copper. The waste gas contains substances such as sulfur and fluorine. The sulfur, fluorine and other substances contain more impurities. As the emission time increases, the impurities in the equipment condense in the flue gas pipe, and the waste gas cannot be discharged normally, causing congestion in the smoke outlet pipe and preventing the equipment from producing normally. This needs to be improved. Therefore, those skilled in the art provide a copper smelting complex flue gas washing and purification device to solve the problems raised in the above background technology. Utility Model Content
