In this paper, a self-designed curved plate dehydration unit system . In theory, the analysis of the flow field inside the curved plate dehydration unit . For song board dehydrated device memory droplets , air flow , and the curved plate wall liquid film in three different fluid state , curved plate the dehydrated device memory in the two-phase flow field , the two-phase gas and liquid phase , third-rate the field of airflow , droplets and liquid film flow field . Principles and knowledge of fluid mechanics , analysis droplet motion and force in the curved plate dehydration unit , the momentum and energy exchange between the three flow field . Through reasonable simplification , it is assumed , to simplify the complex gas-water separator , and derived a mathematical model of each of the three flow field . In order to understand the actual performance of the dewatering device of the curved plate , to industrial wet electrostatic precipitator for the test platform using a novel the mechanical water content measuring apparatus . Curved plate spacing , wind speed and aerosol particles , average particle size of the impact on the curved plate dehydration device performance ( the song board at the outlet of the mechanical water content , dehydration efficiency and resistance loss ) through single factor test : when the the curved plate spacing increases other conditions remain unchanged , the mechanical water content increases , the efficiency of dehydration reduce resistance loss ; when the wind speed increases , ceteris paribus , mechanical water content reduces dehydration efficiency increased resistance loss ; when the atomized particles average increase , ceteris paribus , mechanical water content increased , reducing the efficiency of dehydration , basically no change in the resistance loss . On this basis , the three factors and three levels of orthogonal experiment , the factors affecting the performance of the curved plate dehydration unit do a detailed analysis of primary and secondary order obtained of various factors on the the the dewatering device performance impact of the curved plate , the sequence as: Qu plate spacing , wind speed, pressure . Determined by test analysis the curved plate dehydration units work best combination of performance parameters : the curved plate spacing of 17.5 mm , a wind speed of 3.6 m / s , water pressure of 0.3 MPa , measured the curved plate dehydration device at the outlet of the mechanical water content 4.3 mg/m3, test results fully meet the requirements of the CCPP unit .
