Specifically, the first minimum operating voltage may be any voltage value, and for the obtaining of the first minimum operating voltage, the first minimum operating voltage is mainly based on the first filtering efficiency and the filtering efficiency limit value, and is not determined based on the magnitude of the voltage value. For example, setting the voltage V 1 to 10000V, setting the voltage V 2 to 8000V, calculating first filtering efficiency when the working voltage is V 1, then determining the first filtering efficiency and the filtering efficiency limit value, if the first filtering efficiency is greater than the filtering efficiency limit value, adjusting the working voltage to V 2, then acquiring the first filtering efficiency based on V 2, and if the first filtering efficiency acquired based on V 2 is less than the filtering efficiency limit value, then the first minimum working voltage is V 1.

Specifically, the starting rotation speed refers to the rotation speed of the fan when the fan just starts to work, the rated rotation speed refers to the rotation speed of the fan after the fan enters into work, and the starting rotation speed is smaller than the rated rotation speed, so that when the electrostatic dust collection control system is started, particles which are not adsorbed yet are prevented from being sent out due to the fact that the wind speed of the fan is too high. Wherein the starting rotational speed may be set to 100r/min and the rated rotational speed is set to 2200r/min.
