通过对大型落砂机多种除尘方法的实践,本文着重讨论了气幕射流在落砂机除尘上的机理,并从理论上找到了与实际相符的设计计算方法。经生产实际应用证实,效果十分理想,对国内其他同类型的落砂机除尘,具有一定的参考价值。文中还提出了下一步的设想,有待进一步研究,以期达到更好的经济效果。 Through the practice of many kinds of dust removal methods for large scale sand removing machine, this paper focuses on the mechanism of air curtain jet on dust removal of the sand removing machine, and theoretically find the design calculation method that is in line with the actual. The practical application of production confirmed that the effect is very satisfactory, the same type of other domestic dust removal machine, has a certain reference value. The article also put forward the idea of ​​the next step, pending further study, in order to achieve better economic results.
