一种铁水预处理脱硫喷枪

Hot metal pretreatment desulphurization lance

Abstract

The utility model relates to a hot metal pretreatment desulphurization lance. The technical scheme utilized includes that a lance body (1) is fixedly connected with a framework (3), a refractory material outer lining (2) is poured on the outer wall of the lance body (1), the framework (3) is embedded in the refractory material outer lining (2), a delivery pipe (4) is arranged in the lance body (1), the top end of a vaporizing chamber (5) is communicated with the tail end of the delivery pipe (4), the vaporizing chamber (5) is in a combined shape of a frustum and a cylinder or a cylinder shape, the tail end of the vaporizing chamber (5) is provided with a lance lower outlet, and lateral walls thereof are provided with 2-12 lance side outlets (6). The minimum included angle which is formed between the center line of each lance side outlet (6) and the isohypsic surface ranges from 0 degree to 60 degrees, and each lance side outlet (6) can be a circular hole, an elliptic hole, a flaring hole or a square hole. The hot metal pretreatment desulphurization lance has the advantages of reasonable structure, high desulfurizer utilization rate and high desulphurization efficiency. As air escapes from the hot metal uniformly with continuous bubbles, the lance is stable in injection process with small liquid level fluctuation and small spatter and has low small influence on production environments.
本实用新型涉及一种铁水预处理脱硫喷枪。采用的技术方案是:枪本体[1]与骨架[3]固定联接,枪本体[1]的外壁浇注有耐火材料外衬[2],骨架[3]嵌于耐火材料外衬[2]中,输送管道[4]置于枪本体[1]内;汽化室[5]顶端与输送管道[4]的末端相通,形状为圆台与圆柱的组合形状或圆柱状;汽化室[5]的末端为喷枪下部出口,侧壁上设置有2~12个喷枪侧部出口[6]。喷枪侧部出口[6]的中心线与等高面的最小夹角为0~60°,喷枪侧部出口[6]或为圆形孔或为椭圆形孔或为喇叭形孔或为方形孔。本实用新型具有结构合理、脱硫剂利用率高和脱硫效率高的特点,气体在铁水中逸出均匀,气泡连续,故喷枪在喷吹过程中稳定、液面波动小且喷溅情况少,对生产环境影响小。
