摘要
为了解决农药杀菌剂64%(质量分数)苯醚甲环唑-代森锰锌可湿性粉剂因较强粘附性而在收集过程中清灰难的问题,利用自建的脉冲喷吹滤筒除尘器实验装置,结合流体动力学理论,以平均侧壁压力峰值为清灰效果的评价指标,测试滤筒除尘器在3种不同喷吹条件下的平均侧壁压力峰值。结果表明:滤筒除尘器在3种不同喷吹条件下的平均侧壁压力峰值分别为2.016 2、3.815 4、5.480 7 k Pa;只有当平均侧壁压力峰值达到5.480 7 k Pa时,除尘系统才能连续稳定运行,运行阻力基本保持在1 400 Pa,滤筒清灰效果良好,可以顺利完成粘附性农药粉尘的收集。
To solve the cleaning difficulty for collecting the pesticide fungicide of 64 %（mass fraction） difenoconazole-mancozeb wettable powders due to the characteristics of high adhesion, according to the theory of fluid dynamics and using peak pressure as an index to evaluate the cleaning effect, the average peak pressures along the filter test with three different jet conditions were measured in a self-built pulse-jet cartridge filter test equipment. The results show that the peak pressures along the filter cartridge are respectively 2.016 2, 3.815 4 and 5.480 7 k Pa with three different jet conditions. The cleaning system can operate steadily only when the average peak pressure reaches 5.480 7 k Pa, and the pressures drop of the cartridge filter is about 1 400 Pa, which achieves a good cleaning effect and ensures better collection of the pesticide powders.
