摘要
针对传统离心泵进行脱硫时,工作效率低、达不到节能环保的要求等问题,设计出一种脱硫除尘离心泵。采用速度系数法对脱硫除尘离心泵进行水力设计,并对叶轮和涡室的主要结构参数进行计算。采用CFturbo软件对脱硫除尘离心泵进行三维建模设计,利用Pumplinx软件分别对离心泵内部压力、速度、汽蚀进行数值模拟与分析。模拟结果表明,所设计的脱硫除尘离心泵结构合理,符合实际,满足使用要求,为后面离心泵结构改进和优化提供了依据。
In view of the problems of low efficiency and insufficient energy saving and environmental protection in the traditional centrifugal pump desulfurization, the desulfurization dust removal centrifugal pump is designed. The hydraulic design of desulfurization dust removal centrifugal pump is carried out by velocity coefficient method, and the main structural parameters of impeller and vortex chamber are calculated. The CFDurbo software is used to simulate the desulfurization dust removal centrifugal pump. The pressure, velocity and cavitations of the centrifugal pump are numerically simulated and analyzed by Pumplinx software. The simulation results show that the designed structure of desulfurization dust removal centrifugal pump is reasonable and practical, and satisfying the requirements, and provides the basis for the improvement and optimization of the centrifugal pump.
