摘要
结合目前常用的除尘方式及特点,依据元宝山露天煤矿选煤厂的具体情况,提出了1种基于PLC自动控制的扁布袋式除尘系统,从PLC选型、设计要求、低压控制系统的组成及功能、定时清灰、压差清灰、卸灰、温度检测与控制、监测措施、控制方式、低压控制柜可靠性设计等方面阐述了控制组成,并从除尘装置的设计、除尘器主体设计、除尘器的表面防腐处理、机组安装、调试及试运行等方面探讨了扁布袋式除尘系统设备设计及要求,结合该除尘系统在平庄煤业元宝山露天煤矿选煤厂的应用效果,指出采用具有高可靠性和稳定性的PLC控制系统,可将计算机技术和现场控制技术应用于除尘领域。
Combining with the usual dust removal methods and their characteristics currently, and based on the specific circumstance of Yuanlu coal preparation plant, flat bag type of dust removal system based on PLC automatic control was proposed, the control constitutionwas demonstrated from aspects such as PLC selectivity, design requirement, low pressure control system constitution and functions, fixed time dust removal, differential pressure dust removal, dust unloading, temperature test and control, monitoring control, control method and reliability design of low pressure control cabinet, moreover, from aspects like dust removal equipment design, main body design of dust removal machine, surface antiseptic treatment of dust removal machine, unit installation, debugging and test run, tbedesign and requirements of flat bag type of dust removal system equipment, and combining with application effect in PingmeiYuanlu coal preparation plant of this dust removal system, it was indicated that the PLC control system which had high reliability and stability should be adopted, and the computer technology and site control technology could be used in the dust removal field.
