Used in the process of lead smelting, oxygen-enriched side-blowing furnace smoke and dust secondary recycling device and its process method

Abstract

The invention discloses an oxygen-enriched side-blowing furnace smoke dust secondary return utilization device and a process method thereof in the lead smelting process, and relates to the technical field of oxygen-enriched side-blowing furnace lead smelting. The device used for the secondary return of oxygen-enriched side-blowing furnace smoke and dust in the lead smelting process includes a furnace body, a furnace cover is installed on the top of the furnace body, a recovery mechanism is fixedly installed on the inner side of the upper end of the furnace body, and a cleaning mechanism is installed on the inner side of the recovery mechanism. The ash mechanism, the raw material rack is installed movable inside the lower end of the furnace body, the oxygen inlet is fixedly installed on the left side of the lower end of the furnace body, and the recovery mechanism includes a fixed block, a smoke inlet, a diversion mechanism, a motor, a diversion groove, and a smoke collection piece , out of cigarette butts and dust net. This device is used for secondary recycling of oxygen-enriched side-blowing furnace dust in the process of lead smelting. It is equipped with a recovery mechanism to collect and utilize the secondary soot, and cooperates with the ash cleaning mechanism to avoid the fine particles in the soot when the recovery mechanism recovers the secondary soot. Particles adhere to the inner wall of the device, which adversely affects the working efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of lead smelting by an oxygen-enriched side-blowing furnace, in particular to a device and a process method for secondary recycling of smoke and dust from an oxygen-enriched side-blowing furnace in the lead smelting process. Background technique [0002] After copper smelting soot is extracted by acid leaching, zinc and copper are extracted, 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, coarse tin oxide and matte production process , how to properly dispose of low-lead secondary soot and copper-containing sludge in the smelting process is particularly critical, and oxygen-enriched side-blowing furnaces are often used to treat them; In the form of gas, it enters the dust collection soot, and the rest enters the concentrated matte and slag respectively. [0003] In the ox...

AI Technical Summary

Problems solved by technology

[0003] In the oxygen-enriched side-blown furnaces currently on the market, the secondary soot cannot be fully utilized, and when the soot is transported in the device, it is easy to attach fine dust to the inner wall of the device, causing blockage or slowing down the operation of parts, affecting the working efficiency of the device
