分析并描述了旋转闪蒸干机在干燥三氯吡啶醇钠湿料时其收尘系统所存在的问题,并在国内首次提出用气箱脉冲袋式收尘器对旋转闪蒸干燥机收尘系统进行改造。通过改造后的运行效果证实,气箱脉冲袋式收尘器更有利于三氯吡啶醇钠的收尘,存在粉尘捕集率高、产量大、系统阻力小、能耗低、混料均匀、产品质量好、清灰效果好、维修和换布袋方便等优点。 The problems existing in the dust collection system of the rotary flash dryer when drying the sodium trichloropyridinol wet material are analyzed and described. In the first time, it is proposed to use the air box pulse bag dust collector to clean the rotary flash dryer System transformation. Through the transformation of the operational results confirmed that gas box pulse bag dust collector is more conducive to trichloropyridin sodium dust collection, there is dust capture rate, yield, system resistance, low energy consumption, mixing evenly, Good product quality, cleaning effect is good, easy maintenance and change bags.
