Abstract

Abstract

The problem of unstable particulate emission concentration in the porous electrode electrostatic precipitator （ESP） used for flue gas purification in the header of the sintering machine， is usually caused by the effect of secondary dust lifting. the optimization of the structure and parameters of the vibration device can improve the performance of the dust removal and ensure the high efficiency and stable operation of the porous electrode ESP. Through physical experiments and numerical analysis， the effects of vibration hammer， vibration anvil mass， hammer arm length and suspension method on the tangential vibration acceleration on the plate surface were investigated. The results showed that： with the increase of the vibrating hammer mass， the average tangential acceleration of the plate surface increased by 50%； the tangential acceleration of the plate surface decreased with the increase of the vibrating anvil mass； with an increase of the vibrating anvil mass from 4.4 kg to 5.4 kg， the average tangential acceleration of the plate surface reduced by 10%， and when the vibrating anvil mass exceeded 5.4 kg， the decrease extent reduced significantly； the average tangential acceleration of the plate surface increased with the length of the vibrating hammer arm. The average tangential vibration acceleration of the plate surface increased by 18.2% with the increase of the arm length of the hammer； the tangential vibration acceleration of the plate surface with single-point eccentric suspension was larger than the minimum design value of vibration acceleration of 180 g， and the relative root-mean-square was less than 0.4. In order to meet the requirements of the flue gas de-dusting of the header of the industrial sintering machine， it was optimal to adopt the vibration device with single-point eccentric suspension， a vibration hammer with the mass of 14.83 kg， the length of the arm of 335 mm， in combination with a vibration anvil with a mass of 4.4 kg. This study can provide a reference basis for the design and application of porous electrode ESPs in the ultra-low emission design of sinter headers.
