Natural gas lead smelting device, and lead smelting method using natural gas lead smelting device

Abstract

The invention discloses a natural gas lead smelting device, and belongs to the field of smelting technology. The natural gas lead smelting device comprises a smelting furnace body; the top of the smelting furnace body is provided with a feeding channel; the bottom of the smelting furnace body is provided with a combustion chamber; the smelting furnace is also provided with a gas duct; the combustion chamber is cylinder-shaped; natural gas spray gun holes and air spray gun holes are alternately arranged along the periphery of the combustion chamber; the natural gas spray gun holes are connected with natural gas spray guns; the air spray gun holes are connected with air spray guns; and the inner part of the combustion chamber is connected with an automatic ignitor, which is used for ignition when the natural gas spray guns are activated to work. According to the natural gas lead smelting device, traditional melting furnace structures and combustion methods are changed, natural gas is taken as a fuel, and no coal powder is used for smelting processes in combustion process, so that molten lead purity is ensured, generation of pollutant and slag is reduced, economic benefit is improved, and production cost is reduced. The natural gas lead smelting device possesses extremely high practical application values.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a natural gas lead smelting device and a lead smelting method using the device. Background technique [0002] At present, the smelting of lead-acid batteries, lead, lead sludge and lead-containing waste is generally smelted in pyro-process blast furnaces. This kind of blast furnace uses coal as fuel, which will produce a large amount of harmful gases, pollute the environment, and have low efficiency and lead yield rate. Also low. Furthermore, there is also the use of industrial resistance electric furnaces for smelting and extracting lead. Although this type of electric furnace has no pollution, it consumes a lot of energy. An electric furnace consumes about 600 degrees of electricity to smelt one ton of material, and it takes one hour. Therefore, it is imperative to research and develop low-energy, high-efficiency smelting devices. Contents of the invention [0003] The tec...
