高温沉降式蔗渣干燥系统电气控制及其产业化运用
Electrical Control and Industrial Application of High Temperature Settling Bagasse Drying System
摘要
Abstract
In order to solve the problem that a large number of bagasse with high moisture content produced in sugar cane production has low combustion heat value and side effects on the boiler,a high-temperature settling bagasse drying system is designed.The waste heat source produced in the sugar cane production process is used to effectively reduce the moisture content of bagasse and provide the burning rate of bagasse,saving the use of coal and improving energy utilization.The high-temperature steam or hot water is used to primary heat exchange of the circulating heating water.The circulating heating water then undergoes secondary heat exchange with the air in the processing bin to heat the bagasse in the bin.A negative pressure suction system is used to remove a large amount of water,greatly reducing the moisture content in the bagasse,improving combustion efficiency,saving costs,and reducing environmental pollution,which can meet the continuous drying of a large amount of bagasse.Real time online monitoring of various pressure,temperature,and flow data can be realized through PLC controller and WINCC upper computer.At the same time,the dryness online detection component is used to accurately measure the moisture content of bagasse.After being processed by the PI intelligent algorithm of the PLC program,the speed control of the exhaust and supply system driver is carried out.Combined with the conveying speed,the moisture content of bagasse is ultimately closed-loop and automatically controlled.Effective monitoring is also carried out on key parts of the equipment,the monitoring status are transmitted to the WINCC upper computer to achieve integrated control of the entire system.关键词
