Side-blown furnace and process method for optimizing vertical yield

Abstract

The invention provides a side-blowing furnace with optimized plumb yield and a process method thereof, and relates to the technical field of lead smelting. The side-blowing furnace with optimized vertical yield includes a shell, a feed pipe, a furnace knot cleaning mechanism, an oxygen supply port, a bracket, a knot discharge box, an air outlet pipe, a second furnace knot cleaning mechanism, and a fixed connection at the top left side of the shell. The discharge pipe and the middle part of the top of the shell are fixedly connected with a knot cleaning mechanism, which slows down the formation of knots and cleans the formed knots to prevent the knots from accumulating in the side-blowing furnace. The middle part of the front side of the shell The oxygen supply port is evenly and fixedly connected, the bottom end of the shell is fixedly connected with a bracket, the right end of the shell is slidably connected with a discharge box near the top, the gas outlet pipe is fixedly connected under the discharge box at the right end of the shell, and the left end of the shell is fixedly connected with a second furnace junction close to the top. As for the cleaning mechanism, the invention provides a side-blown furnace with optimized vertical yield, which solves the problem that the formation of knots in the upper part of the side-blown furnace is too fast and the formation of knots reduces the vertical yield.

Description

technical field [0001] The invention relates to the technical field of lead smelting, in particular to a side-blown furnace for optimizing the yield of lead and a process method thereof. Background technique [0002] After copper smelting soot is extracted by acid leaching to extract zinc and copper, the leached slag is fed into the pyrotechnic system, and then added to the oxygen-enriched side-blowing furnace for smelting after batching to make bricks to produce lead-bismuth alloy, crude tin oxide and matte containing lead. Among them, the vertical yield is the core technical index of the whole system, which not only relates to the scope of external raw material market procurement, but also directly affects the economic benefits of the enterprise. [0003] There are many reasons that affect the vertical yield. Among them, when the powdery charge enters the furnace, it is affected by the high-temperature airflow in the furnace, and the powdery charge is blown to the upper pa...
