Description

Technical Field

[0001] The utility model relates to the technical field of electric dust collecting and discharging devices, in particular to an electric dust collecting and discharging device for reducing kiln head dust. Background Art

[0002] Cement production generally uses electrostatic precipitators and bag dust collectors as the main dust collection equipment. For a long time, the application research of electrostatic precipitators in cement plant dust collection has received widespread attention. The electrostatic precipitator is a dust removal equipment that charges dust particles during the ionization of dust-containing gas through a high-voltage electric field, and deposits dust particles on the dust collector under the action of the electric field force, separating dust particles from dust-containing gas.

[0003] After searching, a Chinese patent discloses an electric dust collector and discharge device for reducing kiln head dust (authorization announcement number CN217249723U), which includes an electric dust collector body, a waste heat boiler discharge box connected to the input end thereof, a filter screen slidably connected to the inner wall of the waste heat boiler discharge box, a discharge pipe connected to the output end of the waste heat boiler discharge box, a dust collecting pipe connected to the inner wall bearing of the discharge pipe, a fan blade arranged in an inclined circular array on the inner wall of the dust collecting pipe, and a rotating assembly welded to the outer wall of the dust collecting pipe; the rotating assembly includes a driven gear welded to the dust collecting pipe, a driving gear is connected to the outer wall of the driven gear, a rotating shaft is welded at the center of the driving gear, and a motor is welded to the input end of the rotating shaft. Although the patented technology can effectively avoid the low dust removal efficiency of the existing device by directly absorbing the dust pollutants discharged by the waste heat boiler through the provided rotating assembly, the filter screen and the fan blade, the device is conducive to filtering and screening the dust pollutants before dust removal, thereby improving the dust removal efficiency of the device.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that in the prior art, a plate limiting channel steel is arranged in the electrostatic precipitator to avoid that the distance between the cathode and the anode is too small, and the high-voltage power supply causes induction to reduce its dust removal effect. However, the existing electrostatic precipitator cannot be disassembled. When the plate limiting channel steel is damaged, it is difficult for the staff to replace or repair the plate limiting channel steel in the sealed electrostatic precipitator. At the same time, the prior art uses a filter net to achieve preliminary filtration of dust. However, after long-term use, the surface of the filter net will be covered with a lot of dust, which will reduce the filtering effect of the filter net and greatly reduce the practicability of the equipment.
