摘要
电焊烟尘对人危害极大,必须加以净化才能排放到空气中。然而电焊作业烟尘量极大,由于过滤效率低,导致小型移动式电焊除尘器应用受到限制。为了更好地利用移动式除尘器净化电焊烟尘,研究高效过滤材料变得非常重要。通过数值模拟金属丝绵的除尘效率、过滤压力损失及残余压降等影响过滤性能的因素,将金属丝绵应用于移动式除尘器。为了更好地发挥金属丝绵的过滤性能,设计特殊的过滤结构,并在电焊烟尘除尘器中应用以提高除尘器的过滤效率。结果表明,金属丝绵应用于电焊除尘器可以获得理想的除尘效果,并且可以克服很多现有电焊除尘器的缺点。
The wedding smoke and dust is extremely harmful to human,it must be treated before letting out into the environment.However the amount of welding smoke and dust is very large and makes the filter efficiency much lower,which causes much restriction to the small mobile dust leaner.For making a better use of the mobile dust cleaner,researching high efficient filtering material becomes very necessary.By studying the relationship among collection efficiency,pressure loss,remnant pressure drop and other factors,the filter properties of metal cotton were obtained,and a special filtering structure of metal cotton was designed.The application of the metal cotton filtering structure in welding smoke and dust cleaner shows that the desired dust-removal result can be obtained and many disadvantages of the existing welding dust cleaner can be overcome.
