一种利用碱回收白泥生产流化床燃煤锅炉脱硫粉的方法
摘要：
本发明涉及竹浆制浆造纸技术领域，具体公开了一种利用碱回收白泥生产流化床燃煤锅炉脱硫粉的方法，一种利用碱回收白泥生产流化床燃煤锅炉脱硫粉的方法，包括以下步骤：(1)将胶泥状的湿白泥输送到滚筒式烘干机内，使用温度为600℃-1050℃的热风进行烘干处理；(2)将经过步骤(1)处理后的初级干白泥输送到整选设备中进行整选；(3)将步骤(1)过程中产生的尾气输送到除尘器中进行粉尘回收；(4)将步骤(3)收集的白泥粉尘输送到整选设备中与初级白泥混合整选；(5)将经过整选设备整选过后的白泥按不同颗粒大小分类输送到干白泥仓中包装待用。本发明能提高湿白泥再次利用效率，节约原材料。
摘要（英）：

The invention belongs to the technical field of bamboo pulp pulping and papermaking, and more specifically relates to a method used for producing fluidized bed fire coal boiler desulphurization powder from white mud recovered from alkali. The method comprises following steps: 1, wet white mud in plaster states is delivered into a roller dryer for drying with hot wind of 600 to 1050 DEG C; 2, primary dried white mud obtained in step 1 is delivered into a selecting machine for selecting; 3, tail gas generated in step 1 is delivered into a duster for dust recycling; 4, white mud dust collected in step 3 is delivered into the selecting machine for mixing and selecting with the primary dried white mud; and 5, white mud obtained via selecting using the selecting machine is classified based on particle size, and is delivered into dried white mud storehouses for packaging. The method is capable of increasing reusing efficiency of wet white mud, and saving raw materials.
