摘要

Abstract

Aiming at the problem of internal flue gas bias flow of wet electrostatic precipitators in practical engineering,the Ansys fluent software is used to simulate the flow field distribution characteristics in the side-outlet wet electrostatic precipitator(hereinafter referred to as precipitator)of a 300 MW unit in a power plant.The key factors causing flue gas deviation are predicted,and the inlet guide device of the precipitator is adjusted based on the optimization criteria of inlet flue gas distribution uniformity and maintaining system pressure loss,and the feasibility verification is conducted through engineering cases.The results show that laying flat noodles above the conventional annular flow equalizer for plugging can effectively improve the flue gas bias and improve the uniformity of flue gas distribution.The deviation coefficient CV of velocity distribution in the anode tube bundle area is reduced from 0.31 to 0.18,and the overall dust removal efficiency is increased from 86.2%to 92.4%.
