Electrostatic demisting tube
Thread Content
Previously, fiberglass-based electrostatic demisters were used, but their price seemed a bit high. I would like to ask those with experience: is plastic electrostatic demisting a good option? Specifically, I want to know how such electrodes are manufactured, and how it is possible to ensure their quality under operating conditions. I hope experienced comrades can send some pictures to take a look.
The inner wall of the plastic tube is sandblasted to increase its roughness; therefore, it is necessary to keep the inner wall moist during use in order to meet the electrical conductivity requirements. The same is true for fiberglass electrodemisting; the so-called conductive fiberglass also requires the inner wall of the anode tube to remain moist.
As long as the plastic electrodemister keeps its inner wall moist, the demisting efficiency of both should be similar; conductive fiberglass is obtained by adding conductive graphite to regular fiberglass, thereby improving its electrical conductivity. But fire protection is also necessary during installation, as there have been several cases of actual fires. Now, most manufacturers use fiberglass electrostatic mist eliminators. Actually, plastic ones can also be used; it is essential to ensure that the inner surface remains moist during operation, otherwise the defogging effect will be poor.
