In this work, a low-temperature electrostatic precipitator (ESP) experiment platform was established, and two different electrode configurations were compared under various operating parameters to obtain a method for increasing particle capture efficiency. Results show that, in the case of the rated current, the voltage is significantly affected by temperature variations. Concurrently, by appropriately reducing the flue gas flow velocity of the ESP, the charging time of the particles in the ESP flue can be increased, fully charging the particles and improving the collection efficiency. Moreover, experiments revealed that increasing the relative humidity during ESP operation will increase the particle migration velocity and collection efficiency. Finally, when the electrode configurations were changed from a flat collection plate and round electrode to a sharper needle electrode and a concave-convex structure BE plate, resultantly, all efficiencies exceeded 85% under the temperature range from 50 to 150 °C.

在这项工作中，建立了低温静电除尘器（ESP）实验平台，并在不同的操作参数下比较了两种不同的电极配置，以获得提高颗粒捕获效率的方法。结果表明，在额定电流的情况下，电压受温度变化的影响很大。同时，通过适当降低电除尘器的烟气流速，可以增加电除尘器烟道中颗粒的带电时间，使颗粒充分带电，提高收集效率。此外，实验表明，在 ESP 运行期间增加相对湿度会增加颗粒迁移速度和收集效率。最后，
