Distributed heating magnesite suspension furnace and use method thereof
The invention discloses a distributed heating magnesite suspension furnace and a using method thereof, and belongs to the field of chemical production devices. The distributed heating magnesite suspension furnace is characterized in that a main body is a cylindrical furnace body, wherein a feeding hole is formed above the cylindrical furnace body, a discharging hole is formed below the cylindricalfurnace body, multiple combustion nozzles are arranged on the side wall of the cylindrical furnace body, and the multiple combustion nozzles which are consistent in the horizontal direction of the cross section of the suspension furnace serve as a layer of combustion nozzle ring; and multiple layers of combustion nozzle rings are arranged, wherein the multiple combustion nozzles forming the combustion nozzle rings on each layer are evenly distributed in the circumferential direction, and the combustion nozzles on every two adjacent layers of combustion nozzle rings are staggered in the vertical direction. The using method of the distributed heating magnesite suspension furnace comprises the steps that magnesite is introduced into a cylindrical furnace body, light calcined is carried out at 850 DEG C-950 DEG C, light calcined powder is obtained, and the neutralizing time is smaller than or equal to 30 s. According to the distributed heating magnesite suspension furnace, the internal temperature of a furnace body can be controlled to be uniform, and the activity of the light calcined powder prepared from the furnace body can be remarkably improved.
一种分布式加热菱镁矿悬浮炉及其使用方法，属于化工生产装置领域。该分布式加热菱镁矿悬浮炉，其主体为圆筒形炉体，在圆筒形炉体上方设置有进料口，圆筒形炉体下方设置有出料口，在圆筒形炉体的侧壁上设置有多个燃烧喷嘴，在悬浮炉横截面水平方向一致的多个燃烧喷嘴作为一层燃烧喷嘴环，设置有多层燃烧喷嘴环，每层构成燃烧喷嘴环上的多个燃烧喷嘴呈圆周均匀分布，相邻两层的燃烧喷嘴环上的燃烧喷嘴在竖直方向上彼此错开。其使用方法为，将菱镁矿通入圆筒形炉体中，在850℃‑950℃下进行轻烧，得到轻烧粉，其中和时间≤30s。该分布式加热菱镁矿悬浮炉可控制炉体内部温度均匀，利用其制备的轻烧粉活性显著提高。
