Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a copper smelting furnace smoke waste gas treatment device. Background Art

[0002] In copper smelting production, raw material preparation and pyrometallurgical smelting operations inevitably generate a large amount of smoke and dust due to the combustion of fuel, the effect of airflow on the material, and the physical and chemical effects of metal volatilization and oxidation at high temperature. The existing announcement number is CN 220802531 U, which is a smoke and dust waste gas treatment device. The smoke and dust waste gas is transported to the inside of the gas transmission ring pipe through the air inlet pipe, and then transported to the inside of the treatment barrel through eight air outlet pipes at the bottom of the gas transmission ring pipe. The water inlet pipe valve is opened, and the water source is transported to each atomizing nozzle through the water outlet pipe, the water transmission ring pipe and each water outlet pipe. The water source is sprayed out through the atomizing nozzle by water pressure, so that the smoke and dust waste gas inside the treatment barrel can be sprayed to reduce dust. The water source absorbs and carries out the smoke and dust in the waste gas and flows to the inside of the drainage bucket; however, in the above device, the smoke and the water mist are completely contacted when the water falls downward, resulting in low dust removal efficiency and affecting the quality of dust removal.
