Embodiment
[0017] Such as figure 1 As shown, the first three electric field cathodes adopt the top electromagnetic rapping method, and the latter two electric field cathodes adopt the side rapping method as an example.
[0018] When the dust-laden flue gas flows through the intake smoke box 1 and enters the shell assembly 2, after being ionized by the high-voltage electric field composed of the cathode system 6 and the anode system 5, the dust is collected by the cathode system 6 and the anode system 5, and the clean The flue gas is discharged through the gas outlet smoke box 7.
[0019] The cathode system 6 and the anode system 5 vibrate the collected dust into the ash storage system 3 for collection and discharge.

The invention discloses a novel top and side vibration combined type electric dust remover. The dust remover comprises a negative electrode system, a positive electrode system and a top house; the negative electrode system and the positive electrode system are arranged in parallel to form an electric field; an electromagnetic vibrator is mounted at the top of a front-stage electric field of the negative electrode system; a side vibration hammer is mounted on a rear-stage electric field of the negative electrode system; a suspension device in the front-stage electric field of the negative electrode system is arranged in the top house; and the electromagnetic vibrator is connected with the suspension device. According to the dust remover, the front-stage electric field of the negative electrode system is designed for top electromagnetic vibration, and the rear-stage electric field of the negative electrode system is designed for side vibration; by adopting vibration modes of two structures, the overall layout is compact, and the total weight of the electric dust remover is reduced; and different vibration accelerations can be provided for meeting different dust characteristics and working conditions, so that the dust removal efficiency of the dust remover can be effectively improved, the requirement for ultralow emission of dust can be met, and safe and reliable operation of equipment can be ensured.
Description
technical field [0001] The technology of the invention relates to the cathode rapping structure of an electrostatic precipitator, in particular to a novel top-beating and side-beating combined electric precipitator. Background technique [0002] At present, the rapping methods of the electrostatic precipitator are divided into side rapping, top drive side rapping, and top electromagnetic rapping. Various rapping methods have their own advantages and disadvantages. Side rapping occupies a large space inside the dust collector, resulting in low space utilization of the dust collector. Top electromagnetic rapping does not occupy the inner space of the dust collector, but the rapping effect is not as good as that of side rapping. The effect is good. [0003] In actual working conditions, the dust collected by the front-stage electric field is generally coarse and loose, and adheres to the polar plate and pole line in sheets, requiring relatively small rapping force, while the...
