电除尘器的设计是否合理准确,主要取决于粉尘驱进速度的选取是否符合实际。但是,驱进速度与多种因素有关,而这些因素之间又是相互影响的。目前还没有可靠的计算方法。只能依靠实验的方法进行积累。国外电除尘器制造行业中也多采用模拟试验台的办法来确定粉尘的驱进速度。为了对谏壁电厂第二台30万千瓦机组电除尘器粉尘驱进速度设计值进行校核试验,并为今后新建发电厂电除尘器设计、选型提供科学试验依据。我所与兰州电力修造厂合作,设计制造了一台2m~2移动式电除尘器模拟试验台,装在闵行电厂11号炉旁。
ESP design is reasonable and accurate, mainly depends on the selection of dust driven into line with the actual. However, the driving speed is related to a variety of factors, which in turn affect each other. There is no reliable method of calculation yet. Can only rely on experimental methods for accumulation. Foreign ESP manufacturing industry also use more simulation test bed approach to determine the drive speed of dust. In order to check the design value of the second 300MW unit electrostatic precipitator dust drive speed in the Jianbi Power Plant and provide the scientific test basis for the design and selection of the ESP for the new power plant in the future. In cooperation with Lanzhou Electric Power Plant, I designed and manufactured a 2m ~ 2 mobile electrostatic precipitator simulation test bed, which is installed beside No.11 furnace in Minhang Power Plant.
