Hydraulic filter core vibration should minimize secondary dust from the point of view of reducing secondary dust. The distribution of plate vibration acceleration should be large in the lower part, small in the upper part, large in the front and small in the rear. This is because when the acceleration of the lower part of the plate is high, even if it causes the second flying, it also disappears quickly and does less harm because it is close to the ash hopper. On the contrary, if the upper part of the upper plate vibrates two times, it will diffuse to the whole electric field.
Similarly, even if the inlet plate falls ashes and returns to the airflow, the rear plate will be trapped, and once the secondary dust is generated at the outlet of the electric field at the end, the chance of re-capture will be lost.
Therefore, in this sense, the beating point should be located at the lower end of the plate row, especially at the lower end of the import side of the electric field for the final power plant. Although this arrangement is inconsistent with the requirements of ash removal, it is still a better overall effect scheme on the premise that the vibration acceleration of the upper part of the platen is sufficient for ash removal.
Especially for the rear plate with uniform and thin dust deposit, it is necessary to improve the uniformity of acceleration distribution, increase the vibration intensity and reduce the secondary dust. It is not necessary to emphasize the requirement of the vibration acceleration of the filter element. Air leakage, channeling and erosion will cause two serious dust storms. More efforts should be taken to ban it. Although these mainly depend on the shell design, improper vibration design may also lead to new channeling and leakage, so the vibration mechanism needs to be improved.
