Total oxygen side-blown reduction smelting converter
3.1 Technology introduction
The equipment is mainly used for refining desulphurization or desulfurization lead paste. The process effectively combines traditional precipitation smelting and reaction smelting, and uses the rear combustion way and coherent jet technology, so it can’t only increases gas heat energy utilization ratio of the smelting converter to 20%, but also effectively reduces the exhaust gas and sulfur dioxide emissions. The converter is controlled by PLC control as a whole, therefore, it could automatic materials mixing and charging, automatic producing lead, saving energy and safety, high direct recovery rate of lead, low level of lead in lead slag, little pollution to environment.

Settling chamber and After burner
The equipment consists of many parts, such as settling chamber, after burner, thermal insulation layer, fireproof layer, flue, gate valve, pressure transmitter, temperature controller, concentration of CO detector, burning device and control system, etc. When it passes the large volume sedimentation chamber, the smelting exhaust gas will settle more than 90% of lead dust. Exhaust gas can remain more than 2 s in the tunnel furnace, so carbon monoxide and dioxin will virtually eliminate in exhaust gas. This device implements supervise the temperature and pressure in time to achieve consistency in flue gas combustion. In addition, the “V” flue is created to assist with avoiding lead dust accumulation in it that is between settling chamber and after burner.
