Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The electric dust collector in China mostly adopts a rapping device to remove dust. The rapping device has the task of clearing dust adhered to the electrodes at any time, so that the dust falls into the dust hopper and is discharged in time, which is an important condition for ensuring the normal operation of the electric dust collector. Rapping devices can be broadly classified into three types, electromechanical, pneumatic and electromagnetic. At present, electric dust collectors in China mostly adopt western European style flexible arm vibration. The anode is rapped by a bottom flexible arm hammer, and most of the cathode is rapped by a side rotary hammer. In part of China, electric dust collectors imported from America adopt top cam lifting rapping and top electromagnetic hammer rapping.
The rapping force, rapping period and rapping sequence of the electromagnetic flux rapping device are controlled by a microcomputer rapping device, and each rapping hammer can be randomly controlled within a certain range. The middle part of the dust cleaning device is shaken, most rotating parts are in an electric field, and the reliability and the durability of the dust cleaning device are greatly reduced due to the severe smoke environment of the dust cleaning device. However, if the rapping motor burns out, or the rapping shaft is twisted off or the bearing is worn, the whole electric field rapping is disabled, so that the dust removal efficiency is greatly influenced. The number of the pneumatic rappers is large. However, the detailed rapping unit has small affected area and little influence on the overall efficiency if 1 rapping device fails, thereby improving the overall reliability. According to the investigation of the American society for industrial gas purification on the operation and maintenance of the electric dust collector, the rapping fault accounts for 40 percent of the investigation object, and according to the investigation of China, the failure of a rapping system in an electric field accounts for about 32 percent.
The rapping dust removal of the electric dust remover is an important part in the operation process of the electric dust remover. Whether the electrode is clean or not directly influences the dust removal effect of the electric dust remover. The dust layer adheres to the plate wire because of the electric power. The result of the adhesion and van der waals forces between the plate lines and the dust particles. The high dust resistance electric power is dominant. The adhesive force of the dust is increased along with the increase of the specific resistance of the dust, and for the dust with high specific resistance, a larger rapping force is needed when rapping and washing the dust, so that the accelerated damage of rapping equipment is easily caused. The theory and practice proves that the non-electric pneumatic rapping mode is adopted for rapping to remove ash. Better rapping effect can be obtained. In order to further realize the better deashing effect of dust remover, the utility model discloses an electric precipitation steel ball shakes and beats air hammer.
