提出利用空气预热器引出的热风对电除尘器灰斗进行加热,确定空气预热器管道与灰斗夹层的连接方式,设计出总体方案,通过计算寻找最佳管径、流速、和热风温度等设计参数,分析确定最优方案及其经济性。结果表明,该方案具有良好的技术可行性和较高的经济性。 It is proposed to use the hot air from the air preheater to heat the ash hopper of the electrostatic precipitator and to determine the connection mode between the air preheater pipe and the hopper interlayer and to design the overall scheme to find the optimal pipe diameter, flow rate, hot air temperature And other design parameters, analysis and determine the optimal program and its economy. The results show that the scheme has good technical feasibility and high economy.
