Electrostatic Precipitator System Design And Energy-saving Algorithm Research

Electrostatic precipitators act an important role in decreasing the dust poured into the air. protect environment and human health. It is very important for improving the efficiency of the electrostatic precipitators to optimize the control parameter such as charge ratio and second current limitation.In this paper, dust, the composition of energy-saving control system and its functions, based on the proposed DSP, ARM dual-processor architecture to the next crew monitoring programme and PC software design. With modern networking technology, making all the electric field through the Ethernet controller and the host computer monitoring software for data exchange. Dual-processing application to increase the system's real-time, speed up the computing power at the same time, Ethernet technology allows the processor was originally isolated connected to the network, for single-and multi-field optimization of the electric field provided a good platform.Software design, detailed discussion of the DSP ESP control software design process framework and the steps. Including the reliability of the specific design, sparks and its suppression, communication protocol design, fault and alarm, the current control algorithm design, I/O functional design.In theory on the basis of proposed energy-saving and efficient dust control strategy, including single-and multi-electric field control strategy. In the absence of anti-corona the circumstances, the use of best spark rate control, will have a higher collection efficiency. But when anti-corona circumstances, should be required to reduce the current secondary VI curve inflection point, and through evolutionary algorithms to choose suitable than the charge, reaching energy-saving effect. More and more electric field is to optimize the electric field as a system to consider. Rapping optimize the function is to coordinate the various electric vibration timing, vibration cycle, and a drop-power technology to optimize the fight . Precipitator dust in the capacity surplus, the introduction of closed-loop turbidity, adjusting the distribution of power between the electric field to energy-saving purposes. These strategies integrated into the DSP controller, making ESP according to changes in working conditions, real-time adjustment of the power supply parameters, the precipitator operation in the best condition.Engineering practice indicates the energy saving strategies this dissertation introduces can adapt high resistant dust and low speed dust. It can fulfill the purpose of energy conservation but also guarantee the efficiency of dust collection.
