Background

The electric dust collector is a purification device which separates dust in dust-containing gas from gas by using the action of an electric field, and electrons and anions generated after the gas is ionized are adsorbed on the dust passing through the electric field in the working process, so that the dust is charged. The charged dust moves to the electrode with opposite polarity under the action of the electric field and is deposited on the electrode (anode plate and cathode wire), so as to achieve the purpose of separating dust from gas. When the dust deposited on the electrode reaches a certain thickness, the dust falls into the lower dust hopper by means of the rapping mechanism, and the purified gas is discharged through the equipment, so that the purpose of removing the dust in the flue gas is achieved, the amount of the smoke discharged into the atmosphere can be greatly reduced, and the air quality is improved.

During the operation of the electric dust collector, the properties of the smoke dust are different due to different processes. When the smoke dust with particles passes through the inlet airflow distribution plate and the outlet trough plate, part of the particles are adsorbed on the distribution plate and the trough plate. Along with the increase of time, the more charged particles are accumulated due to the action of electric charges, the uneven distribution of air flow is caused, and the dust collection effect is influenced; therefore, the distribution plate and the slotted plate need to be rapped to remove ash at intervals.

The mechanical arm-winding hammer rapping device is provided with a rotating shaft and a rapping hammer, the rotating shaft needs to be matched with accessories such as a bearing, a coupler and the like, and the mechanical arm-winding hammer rapping device is easy to cause faults after working outdoors for a long time. The moving part of the electromagnetic pulse rapping hammer device is arranged outside the electric dust collector, and can be overhauled and replaced under the condition of no shutdown, but the cost of the electromagnetic pulse rapping hammer device is higher. The vibrating hammer of the mechanical arm-surrounding hammer vibrating device rotates and vibrates once along with the rotation of the vibrating shaft for one circle, and the vibrating hammer is not in contact with the vibrating anvil most of the time. The working environments of the electric dust collectors are different, and the same process may have different characteristics, such as temperature, humidity, dust properties and the like. The highest working temperature of the high-temperature electric dust collector reaches about 500 ℃, the rapping shaft and the rapping anvil are expanded by high temperature to cause displacement, the rapping point is easy to deviate, rapping is inaccurate, the dust collecting effect is influenced, a part of operation components of the mechanical arm-winding hammer rapping device are arranged inside the electric dust collector, and the electric dust collector can be operated only by stopping if the electric dust collector is required to be overhauled or replaced. Therefore, an inlet distribution plate and an outlet trough type plate rapping device of the electric dust collector, which has simple installation and maintenance and low cost, is needed.
