Desulfurization method of light-burned dolomite in rotary kiln
The invention discloses a desulfurization method for light-burned dolomite in a rotary kiln, and belongs to the technical field of desulfurization. The desulfurization method optimizes the existing calcination process and comprises the following steps: adjusting the air distribution proportion of primary air and secondary air, and adjusting the charge level height of a vertical cooler; a kiln head heat compensation mode is adopted for conducting heat compensation on a newly-added denitration system of the rotary kiln tail gas treatment system so that the reaction temperature of the denitration system can reach 150 DEG C or above; the calcination heating time is adjusted to 48 hours; the rotating speed of the rotary kiln is increased, it is ensured that the current fluctuates between 200 A and 230 A, and local high temperature is prevented from being formed. According to the method, the calcining process of the rotary kiln is optimized, and the purpose of desulfurization is achieved under the condition that desulfurization equipment is not invested; and the tail gas SO2 emission reaches the standard (SO2 is less than 35mg/m < 3 >), so that the service life of the denitration catalyst is ensured.
本发明公开了一种回转窑轻烧白云石的脱硫方法，属于脱硫技术领域。所述脱硫方法优化了现有的煅烧工艺，包括：调整一次风与二次风的配风比例，调整竖式冷却机的料面高度；采用窑头补热方式对回转窑尾气处理系统的新增脱硝系统进行补热使脱硝系统达到150℃以上的反应温度；煅烧升温时间调整为48小时；加快回转窑转速，确保电流在200‑230A之间波动，防止形成局部高温等。本发明优化了回转窑煅烧工艺，在不投资脱硫设备的情况下，实现脱硫的目的；且尾气SO2排放达标（SO2＜35mg/m3），确保脱硝催化剂的使用寿命。
