| Abstract: | Analyzing the low voltage control system of electric dust remover (the shakings, supply and unload dust, heat supply system) and its influence on the dust remove efficiency and power consumption. A design plan of new type of low voltage control system which use Siemens S7-226 PLC as its core is brought out. and also a software programming and hardware practice are also made. Through the using of PLC of Siemens S7-226 to develop the serial low voltage control system of large scale electric dust remover and to improve the dust clearing and dust remove function of electric dust remover, and the automatic level of low voltage control system. It not only can reduce the dust in the exhaust gas, make dust removal efficiency keep above 99%, improve the atmosphere environment, but also can reduce the energy consumption. |
