Description

[Technical field]

[0001] The utility model relates to the technical field of flue gas pollutant treatment and electric dust removal, in particular to a gravity lifting drop rod rapping device. [Background technology]

[0002] The electrostatic precipitator is a flue gas purification device. Its working principle is: when the dust particles in the flue gas pass through the high-voltage electrostatic field, they collide with the positive and negative ions and electrons between the electrodes and become charged (or charged during the ion diffusion movement). The dust particles carrying electrons and ions move toward the opposite electrodes under the action of the electric field force and accumulate on the opposite electrodes. The dust on the electrodes is made to fall into the ash collection hopper through vibration and other methods, so that the flue gas passing through the electrostatic precipitator is purified, thereby achieving the purpose of protecting the atmosphere and the environment.

[0003] The hammer head mass and hammer arm length of the traditional rapping device are determined at the beginning of the design, and can only provide a specific rapping force. It cannot be changed according to actual needs and cannot meet the rapping requirements of the electrostatic precipitator. [Contents of the utility model]
