Description

一种减轻无水炮泥生产过程中有害物溢出的处理方法
技术领域
本发明涉及害气体处理领域，特别涉及一种减轻无水炮泥生产过程中有害物溢出的处理方法。
背景技术
无水炮泥是炼铁高炉出铁口重要的功能性耐火材料，无水炮泥传统生产工艺是：生产前预先将焦油之类的结合剂加热到100度左右备用，然后将原料配好后加入到搅拌机中加入焦油搅拌，由于煤焦油、蒽油、沥青等结合剂刺激性气味较重，尤其是生产前对结合剂进行加热过程中会产生难闻的气味，直接排放造成了环境的污染，周围的工作人员的健康也会受到影响。
另外，由于无水炮泥加入结合剂一起加热后粘性很大，搅拌机内的炮泥温度达到60度以上才能出锅成型，一般至少需要搅拌30分钟以上，搅拌时间比较长，搅拌阻力大，影响生产效率的同时，生产了更多有害刺激性气体。
发明内容
发明目的：本发明的目的在于针对现有技术的不足，提供一种减轻无水炮泥生产过程中有害物溢出的处理方法，通过对无水炮泥和结合剂分开加热后再混合搅拌加热缩短了生产周期，同时通过气体净化装置对产生的有害气体进行处理，达到气体排放的标准。
技术方案：为了达到上述发明目的，本发明具体是这样来实现的：
一种减轻无水炮泥生产过程中有害物溢出的处理方法，其特征在于，该方法包括以下步骤：对炮泥原料进行搅拌加热，使炮泥原料的温度为60 -100 ℃，搅拌时间为5-20分钟，搅拌速度为90 - 180r/m；
对结合剂预加热，温度范围为10 -40 ℃；
把预加热后的结合剂添加入炮泥原料中进行混合搅拌，搅拌时间为3-8分钟，搅拌温度为80-150℃，搅拌速度为120-198r/m；
通过风机把上述过程中产生的有害气体引入气体净化装置，风机风量为0.1-5m³/s。结合剂刺激性气味较重，在温度较高的情况下，通常40 ℃时，大量产生有害气体，所以对结合剂预加热，减少结合剂处于高温的时间，从而减少了有害气体产生的时间，只要结合剂开始预加热，风机就开始对有害气体进行收集同时气体净化装置进行处理，确保有害气体外泄。对炮泥原料和结合剂分开进行预加热，此时的炮泥原料粘度低，搅拌速度快，加热效率也高，混合后粘度增加，但是通过前期的预加热，搅拌15分钟就能达到之前搅拌35分钟的效果，也进一步减少了有害气体的产生。
进一步的，在结合剂预加热过程中风机开始工作，风机风量为0.1-0.5m³/s；在结合剂添加入炮泥原料时，风机风量为1-5m³/s。根据实际情况调整分量大小，降低能耗。
进一步的，所述气体净化装置包括臭氧室和活性炭吸附层。达到除臭和杀菌的作用。
进一步的，所述有害气体进入臭氧室停留1-5min，在臭氧室内进行催化氧化，生成半处理气体，所述半处理气体经过活性炭吸附层最终排放到界外。控制停留时间，使有害气体和臭氧充分反应。
进一步的，所述结合剂按重量份数计含以下组份：煤焦油4-8份、蒽油7-10份、沥青4-5份、热硬性酚醛树脂4-8份。采用煤焦油和热硬性酚醛树脂混合，快速加热时体积稳定性和高温粘附性好同时在高温下比纯煤焦油硬化速度快，产生的有害气体相对减少。
进一步的，所述炮泥原料按重量份数计含以下组份：矾土6-8份、刚玉14-18份、碳化硅粉3-4份、焦粉2-3份、粘土5-7份。碳化硅粉提高了炮泥原料的强度、耐侵蚀性和热震稳定性，刚玉熔点高、硬度大、化学性质稳定、耐渣铁侵蚀性好，在高温时转化为α-Al2O3，提高了炮泥原料的抗渣铁冲刷性和抗炉渣的化学侵蚀作用以及炮泥的高温结构强度。
进一步的，所述碳化硅粉按重量份数计含以下组份：硅3-4份、碳化硅4-5份、二氧化硅0-3份。进一步增强炮泥原料的可塑性和烧结性能。
进一步的，所述结合剂占炮泥原料重量的10%-25%。炮泥原料和结合剂安此范围的比例混合，形成的无水炮泥性能较优。
有益效果：
1.结合剂产生的有害气体通过风机收集并通过气体净化装置处理后排放，杜绝了环境的污染。
2.无水炮泥和结合剂分段预加热，然后混合加热，缩短了加热时间，也缩短了有害气体产生的时间。
