    摘要:

    电除尘器是烧结机机头除尘的首选技术,其清灰振打加速度直接决定除尘效率与设备寿命。振打加速度过大会引发二次扬尘,过小则清灰不彻底,二者均会降低除尘效果。在环保要求日益严格的背景下,本文通过综述振打加速度对除尘效率的影响规律,归纳总结市场对振打加速度的技术需求,并对超大型电除尘器的振打加速度进行实际试验测试,梳理出在不同工况条件下阴极和阳极振打加速度的合理范围。结果表明:对于6. 4 m × 5 m(高× 宽)的电场,阳极采用直径为125 mm 的振打锤可使振打加速度为150g ~1 100g,阴极采用直径为95 mm 的振打锤可使振打加速度为50g ~400g,13. 2 m 高度的迷宫收尘装置采用直径为90 mm 的振打锤可使振打加速度为50g ~200g。最后,研制了振打加速度的测试标准和限制值,形成团体标准并修订相关行业标准和国家标准,为电除尘器选型设计提供参考。

    Abstract:

    Electrostatic precipitators are the preferred technology for dust removal at the head of sintering machine. The vibration acceleration used for dust removal directly determines the efficiency of this process as well as the service life of the equipment. Excessive vibration acceleration can cause secondary fugitive dust,and if it is too small,the dust cannot be thoroughly cleaned,both of which will reduce the dust removal effect. In the context of increasingly stringent environmental protection requirements,the influence of vibration acceleration on dust removal efficiency is reviewed,the technical demand of vibration acceleration in the market is summarized,and the actual experimental testing of the vibration acceleration of the ultra-large electrostatic precipitator is carried out,and the reasonable range of cathode and anode vibration acceleration under different working conditions is sorted out. The results show that for the electric field of 6. 4 m × 5 m (height × width),the vibrating hammer with a diameter of 125 mm can be used to make the vibration acceleration of 150g ~1 100g in the anode,the vibration acceleration can be 50g ~ 400g by using a vibrating hammer with a diameter of 95 mm in the cathode,and a vibrating hammer with a diameter of 90 mm can be used for the 13. 2 m height maze dust collection device, which can make the vibration acceleration to 50g ~200g . Finally, the test standards and limit values of vibration acceleration are developed,and group standards are formed and relevant industry standards and national standards are revised to provide reference for the selection and design of electrostatic precipitators.
