High-ferric polymetallic zinc ore smelting furnace

Abstract

The invention discloses a high-ferric polymetallic zinc ore smelting furnace. The high-ferric polymetallic zinc ore smelting furnace comprises a furnace body, a curved tube, a straight tube, a filtrate, a filter box and a water outlet, wherein a fan body is fixed at the lower end of one side of the furnace body, and the straight pipe is fixed at the upper end of the furnace body; and the other endof the straight pipe is fixedly provided with the curved tube, the other end of the curved tube is fixedly provided with the filter box, and the upper end of the interior of the filter box is fixedlyprovided with an air outlet. According to the high-ferric polymetallic zinc ore smelting furnace, disassembling and assembling can be better achieved, aged and blocked pipelines can be conveniently replaced, and the replacement inconvenience and economic loss caused by replacement of the whole pipelines due to aging and blocking are avoided; and the phenomena that due to the fact that particles are accumulated for a long time, the curved pipe is blocked, exhaust of waste gas is too low, the smelting efficiency is reduced, and the air pressure in the smelting furnace is too high, the explosionof the smelting furnace is caused, economic losses caused by the damage of the smelting furnace are caused, and the life safety of surrounding people can be threatened seriously are avoided.

Description

technical field [0001] The invention belongs to the technical field of mineral smelting, and in particular relates to a high-iron polymetallic zinc ore smelting furnace. Background technique [0002] Smelting furnace refers to a furnace that melts iron ore, such as melting hematite (Fe2O3) or magnetite (Fe3O4), to turn it into pig iron. This furnace body is a tall columnar structure lined with refractory materials, filled from the top Into washing ore, coke and solvent (the solvent is usually limestone). The conversion of iron oxide to metallic iron is a reduction process in which carbon monoxide and hydrogen are used as reducing agents. [0003] The prior art has the following problems: 1. It is very troublesome to replace the pipeline after it is blocked or aged; 2. The particles are easy to block the pipeline of the gas outlet, causing the gas to be blocked and reducing the discharge efficiency. Contents of the invention [0004] In order to solve the problems raised ...
