针对国内外空气滤清器使用中出现的问题,在分析除尘与作用粒径关系的基础上,提出了离心—静电组合除尘方式。结合S195型柴油机,考虑外形、结构尺寸、静电发生装置等因素,设计出新型的离心—静电式空气滤清器。试验结果表明,新型空气滤清器的过滤效率达到标准,且功率和耗油率都较原空气滤清器有较大的改善。 Aiming at the problems in the use of air filter at home and abroad, a centrifugal-electrostatic combination dust removal method is proposed based on the analysis of the relationship between dust removal and particle size. Combined with S195 diesel engine, considering the shape, structure size, electrostatic generator and other factors, the design of a new type of centrifugal - electrostatic air cleaner. The test results show that the new air filter has reached the standard filtration efficiency, and power and fuel consumption than the original air filter have greatly improved.
