Electrostatic demister is a gas-liquid separation wet equipment with less resistance to purification fluid

The gas temperature in the electrostatic precipitator equipment is lower than the dew point, which will cause chemical corrosion. Due to the condensation of H20-H2SO4, it will cause leakage on the surface of the insulator, or stick dust on the electrode wire, or form an insulating covering film. Therefore, the gas temperature should always be kept above the dew point. On the other hand, attention should also be paid to the faults caused by the thermal stress of the components at a high temperature above 500°C. Operate around temperature.

The discharge electrode of the electrostatic demister is broken due to dust adhesion, insulation film formation, corrosion, and poor equipment quality, or it needs to be replaced because it is bent and cannot be corrected. When using sulfur ore and zinc ore, an insulating film is often formed on the discharge electrode. In summary, it should be replaced every 1-5 years. The reason for replacing the discharge electrode in the demisting device is roughly the same as that in the dust removal device. When the star-shaped protruding part is seriously damaged, it needs to be replaced.

There are a lot of precautions when using the electric demister. Don't take these precautions seriously. You must operate according to the manufacturer's instructions, so as to avoid many unnecessary problems.

The floor-standing electrostatic demister is a gas-liquid separation wet-process equipment with small purification fluid resistance. It is a must-have equipment in many sulfuric acid factories. Acid mist treatment. So how do we make the electric demister operate normally? Let me briefly talk about it below.

In order to make the wet electrostatic demister operate effectively, the high voltage should be increased as much as possible. Therefore, special attention should be paid to the insulation of the conductive part and the ground, and the structure and material of the bracket. If water and dust are attached to the surface of the insulating ceramic bottle or mixed with the insulating oil of the electric demister for demisting, the electrical insulation will be significantly deteriorated, and the useful voltage will drop. Use a 1000V megohmmeter to measure a completely cleaned insulation The insulation resistance of the porcelain bottle is about infinite, and it should be insulated at least above 20Mn. Porcelain bottles should be cleaned regularly according to the usage and environment, and the insulated porcelain bottles should be put into the box and sent into the hot air to avoid the influence of moisture and dust.

In the case of electric defogger thyristor rectification, the temperature has a certain influence on its operating characteristics and life, so it is necessary to pay attention to the temperature rise around the thyristor, and the thyristor rectifier is stored in a storage tank. Because they are often cooled by insulating oil, the temperature rise is not a problem, but pay attention to the pollution of the moisture absorbing breather. If the moisture absorbing breather is polluted, the water entering the insulating oil of the storage tank will often cause the deterioration of the insulation function.
