Model selection design device and method for low-low-temperature electric precipitator

The invention discloses a model selection design device and model selection design method for a low-low-temperature electric precipitator. A round wire-plate structure is adopted to replace a needlingwire-plate model and a numerical model of the low-low-temperature electric precipitator is established on the basis of the round wire-plate structure; the time for predicting the performance of theneedling line-plate model low-low-temperature electric dust remover through numerical simulation is greatly shortened; the performance of the low-low-temperature electric precipitator is directly usedfor model selection design of the low-low-temperature electric precipitator through numerical simulation prediction. The problems that in the prior art, the needle-punched wire-plate low-low-temperature electric dust remover is large in analog calculation amount and long in calculation time are solved, and direct engineering application of the technology for predicting the performance of the low-low-temperature electric dus
