垃圾焚烧炉尾气中的有害物质和燃煤锅炉煤中的硫燃烧后主要是以二氧化硫的形态存在，这种呈气态的二氧化硫和有害气体是无法用任何其它种类除尘器收集和捕捉的。本技术是通过向含有粉尘、二氧化硫和有害气体的烟气中喷射熟石灰干粉和反应助剂来实现脱硫、脱有害气体的。二氧化硫、及有害气体和熟石灰在反应助剂的辅助下充分发生化学反应，形成固态硫酸钙(CaSO4)和其它附着物，附着在粉尘上或凝聚成细微颗粒，随粉尘一起被袋式除尘器收集下来。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。

Digital image processing technology,the present reseach level about image alarm system is to separate eyewinker from monitoring image,and to judge whether the eyewinker is harmful according to the size of the area of object,this method is imprecise and suspectable.The image recgnition alarm system isan apply on image processing technology.when a foreign object enter monitoring place,we will segment、measure object,and analysis、judge through proportion characer or invariant monent.the result of the parameter will decide whether the eyewinker is harmful,if the object is harmful ,system will auto-startalarm device.

而本设计的主要特点是基于了数字图像处理技术，目前传统图像报警系统的研究水平是将异物从监控图像中分离出来，然后依据异物面积的大小来判断异物是否有害，它对异物有害的判断十分不准确，这种判断结果的有效性是很值得怀疑的；针对于这些弊端，本课题在数字图像处理技术上的应用是对监控场所进行全景监控，如有异物进入，对异物进行分割、测量，从不同的角度进行了分析和判断，进而决定异物是否有害，若满足场景所规定的有害条件，则启动报警装置，发出报警信息。
