PSA横向充氮气调与惰性粉防治技术综合应用研究

STUDY ON COMPREHENSIVE APPLICAITON OF PSA NITROGEN-FILLED CONTROLLED ATMOSPHERE AND INERT POWDER CONTROL TECHNOLOGY

在高大平房仓进行PSA横向充氮气调,累计充气时间34 h,整仓氮气浓度达98%以上,该工艺具有自动化程度高、气体浓度均匀性高、使用能耗低、杀虫效果好等特点.充氮结束后使用惰性粉气溶胶防治技术,能有效防止虫害再次发生,极大地延长无虫间隔期,实现免熏蒸、免气调,达到安全储粮的目的.

The PSA Nitrogen-filled of the large warehouse,the cumulative inflation time is 34 hours,and the nitrogen concentration of the large warehouse is over 98%.The process has high automation,high gas concentration uniformity,low energy consumption and good insecticidal effect.The use of inert powder aerosol control technology after the end of nitrogen filling can effectively prevent the recurrence of insect pests,greatly prolong the interval of no insects,achieve fumigation-free,air-free regulation,and achieve the purpose of safe grain storage.
