Copper Fire Refining Lv Automatic Compensation Of The Solid Reductant Injection System Application Process

At present the majority of Yunnan Copper using solid reductant, such as the Copper Fire refineries are subject to the artificial receivership, the cans, batch mode to reducing transmission, refining furnace injection to restore operations. That way labour intensity, tedious operation, reducing operational needs of the large number of (at least three people), the reduction furnace atmosphere of instability, large consumption, and the reducing agent or improper control of water impurities outer entrainment, the reduction process often plug, resulting in copper water intrusion, the reduction process more time-consuming. To this end, the project team and the Yunnan Copper Industry Co., Ltd. has developed a new generation of solid copper Fire Refining reducing transmission, injection technology systems: Copper Fire Refining solid reductant LV automatic compensation injection system, which can be Reduction of solid reductant operation automation, while achieving long-distance transmission and injection with automatic, efficient, safe and environmentally friendly, intensive features.The purpose of the study of this topic: solid reductant LV automatic injection system because of its development is not long, in the use of the production equipment there may be many details on aspects of the production data collected by tracking, recording the various problems in the production, and sampling Laboratory analysis study and solve production problems and improve systems to make the system better adapt to the needs of production, thereby reducing LV solid automatic injection system the greatest extent possible to facilitate production.The research topics include: 1. Successful development Copper Fire Refining solid reductant LV automatic injection system and form a complete set of equipment used in Yunnan Copper Industry Co., Ltd. and Refining Factory 2-rotating anode furnace2.Conduct Theoretical studies, and technical personnel to real physical and chemical processes to provide a theoretical basis, 3. production by tracking data collected at the scene, according to data analysis and production of a theoretical study, in combination with laboratory experiments to identify the chemical composition of solid reductant and physical Properties and application of adaptive equipment; 4. record of the production process there are all sorts of issues, and sampling for laboratory analysis, problem solving and improving the system so that the system can better meet the needs of production.By analyzing emerging from the study: 1. Fire suitable for copper refining solid reductant LV Injection System Restore automatically refining a new type of solid reductant components: water≤6, ash≤15, volatile≤15, total sulfur≤0.5,≤5 additives, fixed carbon≥70; traditional injection consumption of 11 to 13Kg/t-Cu single furnace reduction time is 30 to 60 minutes; black smoke grading standard used is Ringlemann chart of one, relative reduction of heavy oil Each one tons of copper production can be reduced cost savings 10.8 yuan, a decrease of 45%; 2. solid reductant size requirements for: 0.2-5mm>80%, at room temperature for the temperature materials; wind blowing compressed air pressure: 0.30 ~ 0.60MPa, the wind capacity: 5～6Nm~3/min, nitrogen requirements: 4～5m~3/min;3. LV automatic injection system development in the implementation of the major issues and lessons learned: arising in the course of trial production of a furnace pipe "plug" situation, because the system has emerged in the external granule "foreign body" in a number of pilot production under vibration filtering material of the poor, because vibration control filtering sieve sieve size smaller, solid reductant size too small (too many powdery materials, particle size <0.5mm accounted for 45 per cent) and high moisture materials, process steam wind aquifer material at the site led to the expected wet; V-type valve can not adapt to the problem. 4.LV automatic injection system application results: compared with the traditional solid reductant injection devices, reducing consumption can reduce, reduce production costs and shorten the time reduction, and can reduce operation The labor intensity, increase productivity, improve the production and operation environment.
