Description

Technical Field

[0001] The invention relates to the field of electric bag dust collectors, and in particular to a rapping mechanism. Background Art

[0002] An electrostatic bag filter is a highly efficient, composite dust removal device that combines an electrostatic precipitator (ESP) with a bag filter. It is widely used for flue gas purification in coal-fired power plants, steel, cement, and other industries. Dust-laden flue gas first enters the ESP area, where a high-voltage electric field charges dust particles and traps them on collecting plates. After ESP, the flue gas enters the bag filter area, where fine dust not captured by the electric field is filtered by the filter bags. The dust layer on the bag surface further intercepts fine particles, and the purified flue gas is discharged through the clean air chamber. Currently, ESPs are the most commonly used for boiler flue gas treatment.

[0003] For electric bag dust collectors, vibration is an important link to ensure its efficient operation. The purpose of vibration is to remove dust accumulation and prevent efficiency from decreasing. During the electrostatic precipitator stage, when the dust-laden flue gas passes through the high-voltage electric field, the dust particles are charged and captured on the anode plates and cathode wires; as the operating time increases, a dust layer will gradually accumulate on the anode plates and cathode wires; if not removed in time, the dust accumulation will cause the electric field strength to decrease, affecting the dust charging and capture efficiency, and thus reducing the overall dust removal efficiency; by vibrating the anode plates and cathode plates, the dust accumulation can be removed and the capture capacity of the electric field can be restored.

[0004] Avoid back corona phenomenon. When the dust layer accumulated on the anode plate or cathode wire is too thick and the dust resistivity is high, back corona phenomenon is likely to occur. Back corona will lead to increased energy consumption of the electric field, deterioration of the current-voltage characteristics, and even cause an electric field short circuit. Vibrating operation can effectively reduce the thickness of the dust layer, reduce the risk of back corona, and ensure stable operation of the electric field.

[0005] Maintain the stability of the electric field. Dust accumulation not only affects the dust removal efficiency, but may also cause local discharge or short circuit inside the electric field. The vibration of the anode and cathode plates can prevent dust from forming conductive bridges on the electrode surface, maintain the appropriate distance between the electrodes, and ensure the electric field strength and uniformity, thereby ensuring the stable operation of the electrostatic precipitator stage.

[0006] Reduce equipment load and extend service life. Dust accumulation will increase the weight of the anode plate and cathode wire, resulting in an increase in the load on the rapping system and may even cause deformation or damage to the electrode. Regular rapping can reduce equipment load, reduce mechanical stress, extend the service life of electrodes and related components, and reduce maintenance costs.

[0007] To ensure the subsequent bag dust removal effect, in the electrostatic bag dust collector, the main function of the electrostatic precipitator stage is to remove most of the coarse dust particles and reduce the load of the subsequent bag dust removal area; if the efficiency of the electrostatic precipitator stage decreases due to dust accumulation, a large amount of dust will enter the bag dust removal area, increasing the filtration load of the filter bag and accelerating the clogging and wear of the filter bag; vibrating the anode plate and cathode plate can ensure the efficient operation of the electrostatic precipitator stage and provide good entrance conditions for the bag dust removal area.

[0008] Adapt to different working conditions. When dealing with high resistivity dust or fluctuating fluctuating flue gas conditions, the anode and cathode plates are more prone to dust accumulation. By adjusting the vibration frequency and intensity, it can adapt to different working conditions and ensure that the electric bag dust collector can maintain efficient operation under various conditions.

[0009] Therefore, vibration is extremely important for electric bag dust collectors. In the authorized Chinese utility model patent "Announcement No.: CN220496612U, Name: A vibration device for an electric precipitator", the piston rod of the cylinder is retracted through the control of an electromagnetic reversing valve. After a preset time of five seconds, the piston rod of the cylinder is extended through the control of an electromagnetic reversing valve. Since the connecting air pipe of the lower cavity part of the cylinder is provided with a quick exhaust valve, the cylinder is extended quickly at this time, and the gravity of the heavy hammer itself is used to vibrate the plate of the electric precipitator to remove dust. However, in the above application, precise coordination between the electromagnetic reversing valve, the cylinder and other equipment is required, which makes the production and use costs of the vibration mechanism high. In addition, the electric precipitator in the above application only vibrates the anode plate, resulting in poor cleaning effect in the power plant area, affecting dust collection. At the same time, in the existing technology and the above application, the vibration position of the vibration mechanism is fixed. For differences in the distribution of dust accumulation on the motor or uneven dust characteristics, the fixed position vibration cleaning effect is poor, which affects the normal use of the electric bag dust collector.
