Abstract:
Taking the dual-chamber five-electric field dry electrostatic precipitator system of a coal-burning power station 320 MW unit as the object,we test the characteristics of dust collection under 4 groups of different types of power conditions,and discuss the influence of pulse power on the dust removal performance. The influence of different types of power on the grading efficiency of dust collection each electric field are further analyzed. The result shows that the efficiency of the dust cleaning system tested can be more than 99.79% under four power operation conditions. The comparative tests show that pulse power supply can not only reduce energy consumption greatly,but also increase the removal efficiency of fine particles significantly. Especially,the difference of efficiency of dust collection is more significant with the dust particle size smaller. The dust particles are charged fully in the electric field of increased charging intensity with the rise of working voltage appropriately to improve the dust capture efficiency.
