As we all know, the electric collector cell of the oil fume electrostatic precipitator on the market is divided into plate type and honeycomb type.But in fact,the working principle of these two models is basically the same.They both absorb the oil fume through the voltage difference,but the plate electric collector cell is more of a combination of high and low voltage,ionization in the high voltage area,and adsorption in the low pressure area to complete the purification of oil fume.The honeycomb is ionized by the electric charge generated by the cathode rod,adsorbed on the pipe wall of the anode and adsorbed.
In terms of purification efficiency,the purification speed of the plate electric collector cell is lower than that of the honeycomb under the same wind speed.Because the voltage of the plate electric collector cell is lower than that of the honeycomb,the adsorption capacity is weaker,and it needs to pass through a certain interval,which means that the contact area needs to be increased,so the width of the plate electric collector cell is generally wider than that of the honeycomb.According to the experimental data,the distance between the plate electric collector cell pole pieces needs to be at 7mm,the thickness of the pole piece needs to be more than 1mm,and the smoothness of the pole piece also has certain requirements.In the honeycomb electric collector cell,the key factors are the diameter of the honeycomb,the voltage,and the passing wind speed.The wind resistance of the honeycomb is relatively larger than that of the plate type,and the flow rate is low,so the honeycomb purification efficiency is slightly higher.
