Heat supply structure for furnace bottom of anode roasting furnace

阳极焙烧炉炉底供热结构

Abstract

本发明涉及一种供热结构,尤其涉及铝用阳极生产领域的敞开式阳极焙烧炉的阳极焙烧炉炉底供热结构。阳极焙烧炉炉底供热结构,由下述结构构成:设在炉室底部的加热通道,加热通道的一端与燃烧通道相通,加热通道的另一端与排烟通道相通,在排烟通道上设有与火道墙相通的烟气排出孔。本发明的优点效果:可明显改善阳极焙烧炉料箱内的温差,有利于提高阳极产品的质量,提高成品率和焙烧工段的经济效益;可为降低火道温度提供先决条件,明显降低阳极焙烧生产的燃料消耗;可大幅度提高火道墙的使用周期,进而有效延长阳极焙烧炉的大修周期,在节约炉子维修费用的同时,可大幅度减少由于修炉带来的固体垃圾排放;结构简单,经济实用,易于实施。
The invention relates to a heat supply structure, in particular to a heat supply structure for the furnace bottom of an anode roasting furnace, which is applied to open type anode roasting furnaces in the production field of anodes for aluminum. The heat supply structure for the furnace bottom of the anode roasting furnace is formed by following structures that a heating channel is arranged at the bottom of a furnace cavity, one end of the heating channel is communicated with a burning channel, and the other end of the heating channel is communicated with a smoke exhaust channel which is provided with smoke exhaust holes communicated with a flame path wall. The heat supply structure has the advantages of obviously improving temperature difference in a material bin of the anode roasting furnace, being favorable of improving quality of anode products, improving rate of finished products and economic benefits of roasting work sections, providing precondition for reducing temperature of aflame path, obviously reducing fuel consumption of anode roasting production, remarkably prolonging service life of the flame path wall, effectively prolonging overhaul period of the anode roasting furnace, saving maintenance cost of the furnace, simultaneously reducing emission of solid rubbish brought by furnace maintenance remarkably, and being simple in structure, economic, practical and easyto implement.
