【技术实现步骤摘要】
本技术涉及一种钼粉还原炉,属化工设备领域,更具体的说是涉及一种基于两用还原炉的钼粉还原系统。
技术介绍
金属钼粉是钼深加工产品的基础原料,目前国内生产的钼粉主要采用的氢气还原氧化钼的方法生产,钼粉的质量直接影响着深加工产品的质量,尤其是钼粉的粒度、形态、纯度等,而影响钼粉的这些物理性能主要是炉体结构、温度控制、反应压力、炉管内水蒸气含量等因素,而影响炉内反应压力和水蒸气含量的主要是还原炉的氢气的合理控制。现有的还原炉在添加氢气时都是采用的固定压力进行添加,在添加氢气过程中难免会影响炉内的反应压力,同时在还原后的废气中含有大量未燃烧的氢气,这些废气一般都是直接在废气出管口点燃烧掉,浪费了能源,增加了用氢成本。
技术实现思路
