Optimization Of The Overall Structure Of Electrical Flow Field Precipitator

With the increasing development of industrial technology, our environmental requirements are also increasing. Therefore, looking for a more effective manner to improve the collection efficiency of the electrostatic precipitator and reduce dust emissions from the electrostatic precipitator become the research direction of scientists. In order to save labor time and cost reductions, numerical simulation can be used to study the way air distribution inside the precipitator.The simulating model of this paper as the prototype of electrostatic precipitator with area of 260m2.This paper in accordance with FLUENT simulation software, select the appropriate method to simulate the flow field inside the ESP flow characteristics and research the relationship between the deflector, air distribution and flow field plates, etc.Firstly, collect power plant electrostatic precipitator design data, then establish ESP and mesh by Gambit software stereoscopic three-dimensional model. Then import the meshed file into the software FLUENT. Using the suitable method to setting the fluid region and determine the appropriate boundary conditions to prepare the necessary steps of numerical simulation. Then we won the airflow distribution inside the electrostatic precipitator of the conditions of without air distribution Edition, setting one piece of air distribution plate and deflector and setting a horizontal baffle. Thus, we obtained the picture of static pressure contours, flue trend graph, velocity vector, etc. By comparing the pictures we arrive at a more reasonable air distribution scheme. In the last, by ESP imports smoke box to add internal transformation where the horizontal baffle are simulated, we analysis the feasibility of such programs.
