I. Introduction.
In industrial production, the electric tar precipitator is a commonly used equipment, which is mainly used to treat tar in flue gas. However, in practice, we found that the secondary current of the electric tar precipitator was sometimes on the high side. The secondary current is one of the important parameters for the operation of the electric tar precipitator, and its increase may affect the operating efficiency of the equipment. Therefore, this article will ** the reasons for the high secondary current of the electric tar precipitator.
Second, the reason for the high secondary current of the electric tar precipitator.
1.Electrode surface cleanliness: If there are impurities or contaminants such as soot on the electrode surface, it will affect the uniform distribution of the electric field, resulting in high secondary current. Therefore, it is necessary to clean the electrode surface regularly.
2.Electric field strength: Too high or too low electric field strength will affect the secondary current. Excessive or low electric field strength may lead to uneven distribution of the electric field, which in turn affects the separation of tar and flue gas. Therefore, the electric field strength needs to be adjusted according to the actual situation.
3.Flue gas velocity: The flue gas velocity affects the stability of the electric field and the secondary current. A flow rate that is too high or too low can cause the electric field to become unstable, which in turn can affect the secondary current. Therefore, it is necessary to control the flue gas velocity reasonably.
4.Equipment aging: As the equipment is used for more time, the electrodes and insulating materials may deteriorate, which can also affect the uniform distribution of the electric field and the secondary current. Therefore, it is necessary to regularly inspect and maintain the equipment.
3. Solution.
In view of the above reasons, we can take the following measures to solve the problem of high secondary current:
1.Clean the surface of the electrode regularly to ensure its cleanliness.
2.Adjust the electric field strength according to the actual situation to ensure that the electric field is evenly distributed.
3.Reasonably control the flue gas flow rate to ensure the stability of the electric field.
4.Regularly inspect and maintain the equipment, and replace aging parts in a timely manner.
IV. Conclusions. The high secondary current of an electric tar precipitator can be caused by a variety of factors, including electrode surface cleanliness, electric field strength, flue gas velocity, and equipment aging. Understanding these causes and taking corresponding measures can effectively solve the problem of high secondary current and improve the operation efficiency of the electric tar precipitator. Therefore, we should regularly inspect and maintain the equipment to ensure that it is functioning properly.
