Closed heating lead smelting system

Abstract

The invention discloses a closed heating lead smelting system. The closed heating lead smelting system comprises a smelting furnace, wherein a charging position of the smelting furnace is connected with a feeding device, a lead slag filter is arranged below the smelting furnace, a separation transportation device is arranged below the lead slag filter, the separation transportation device is provided with a lead collector below the lead slag filter, a waste gas exhaust opening in the upper part of the smelting furnace is connected with a dust-removal deacidifying device, and the dust-removal deacidifying device, smelting furnace, lead slag filter and lead collector are correspondently matched with one another in a closing manner. Waste lead is transported to the smelting furnace by virtue of the feeding device to be heated and smelted, molten lead falls into the lead collector after being filtered by the lead slag filter, and smelting waste gas is treated by the dust-removal deacidifying device and then is exhausted. The closed heating lead smelting system treats the lead in a closing manner in the whole process, the waste gas treatment effect is good, no pollutant is exhausted, the environmental pollution is avoided, the continuity production can be realized, automatic production can be realized, and the lead recovery rate is high.

Description

technical field [0001] The invention relates to a lead smelting technology, in particular to a closed heating lead smelting system. Background technique [0002] my country is the world's largest producer and consumer of lead-acid batteries, and the amount of waste batteries produced is huge. At present, the production technology of the domestic recycled lead industry is still in a state of backwardness, dispersion and serious environmental pollution. The smelting method of lead materials is generally used The precipitation smelting method with iron filings, the production equipment is mainly the intermittent smelting reverberatory furnace with feeding on the top of the furnace, there are also small blast furnaces, some even cupolas, crucible furnaces, etc., using metallurgical coke, cupola smelting is frequently started and shut down , more lead loss. Comprehensive recycling of waste lead-acid batteries is still an important issue facing the current domestic secondary lead i...
