[0002] The traditional top-bottom composite rapping electrostatic precipitator includes anode plate, support beam, support plate, top rapping anvil, rapping rod and bottom rapping anvil, wherein the support beam is set on the top of the anode plate, and the support beam is set on the top of the support beam. There is the support plate, the top rapping anvil and the first rapping device are installed on the support plate, and the first rapping device is located at the rear of the top rapping anvil; the bottom of the anode plate is provided with the rapping The left end of the rapping rod is provided with a bottom rapping anvil, and a second rapping device is provided on the left side of the bottom rapping anvil. The second rapping device has the same structure as the first rapping device. The beating device includes a base, a hammer arm and a hammer head, wherein the hammer arm is hinged on the base, and the hammer head is installed at the lower part of the hammer arm, and the quality of the hammer head and the length of the hammer arm are determined at the beginning of the design. Generally, they cannot be changed, so that the rapping mass and arm length of the first and second rapping devices cannot be changed, resulting in the non-adjustable rapping intensity, which can only provide a specific preset rapping force, and cannot provide variable vibration. hit hard

In the actual working process of the electrostatic precipitator, the required rapping force is greatly affected by factors such as the thickness of the accumulated dust, the characteristics of the dust, the working environment, and the operating conditions of the equipment, and these factors are different from the preset conditions. It is very easy to make the preset rapping force too small or too large. If it is too small, the dust layer cannot be separated from the anode plate, and the dust removal is not complete, resulting in serious dust accumulation on the surface of the anode plate, which affects the working efficiency of the electrostatic precipitator. Too large , and the dust layer will be vibrated, resulting in secondary dust, which cannot better meet the requirements of rapping; therefore, it is urgent to solve the above technical problems
