摘要由于我国现有大气污染状况不容乐观，且各地除尘设备效率低下，因此治理煤烟型大气污染必要而紧迫。本设计即是对于燃煤锅炉烟气除尘设备的选型。按照燃煤锅炉的额定蒸发量，确定锅炉的型号及参数；根据选定煤种的特性，计算耗煤量、烟气体积、烟气粉尘浓度，根据燃煤锅炉烟气排放标准计算除尘效率。根据当前我国现有高效除尘器的种类与除尘效率综合分析，最终选择使用电除尘器。根据要求计算电除尘器的各部分尺寸，并绘制电除尘器的主视图、左视图及进口法兰图。51460

700 t / h Coal-fired Boiler Flue Gas Dust-removal Equipment Selection and Design

Abstract

It is very necessary and urgent to control smoke pollution of our country due to the serious air pollution and poor efficiency of the dust removal equipment. This is the design for coal-fired boiler flue gas dust removal equipment selection. The model and parameters of the boiler were selected according to the rated evaporation of coal fired boiler. According to the characteristics of selected coals, the coal consumption, the volume of flue gas and the dust concentration of the flue gas were calculated. The dust removal efficiency was calculated according to the flue gas emission standard of coal fired boiler. Electric dust collector was selected through the analysis of the existing types of efficient dust collector in our country and their dust removal efficiency. The size of each part of the electrostatic precipitator was calculated according to the requirements. The main view, the left view and the inlet flange of the electric dust collector was drawn.

Key Words: Dust removal equipment  a circulating fluidized bed boiler  electrostatic precipitator
