Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, and particularly relates to an electrostatic precipitator. Background Art

[0002] An electrostatic precipitator is an important environmental protection device for improving environmental pollution and air quality. Its working principle is to remove dust particles in the flue gas discharged from coal-fired or oil-fired boilers, thereby greatly reducing the amount of soot discharged into the atmosphere. The existing electrostatic precipitator includes a casing, with an air inlet and an air outlet provided on both sides of the casing. A number of electrostatic fields are evenly distributed along the direction from the air inlet to the air outlet of the casing. Each electrostatic field has a number of electrode plates arranged in parallel. When the flue gas passes through the electrostatic precipitator, the dust particles in it are adsorbed by the electrode plates, thus achieving the effect of purification and dust removal. In the existing technology, a rapping mechanism is installed in the electrostatic precipitator. By rapping and vibrating the electrode plates through the rapping mechanism, the dust particles are detached from the electrode plates. However, it is always impossible to achieve a comprehensive cleaning, resulting in the need to frequently use the rapping mechanism to clean the dust particles. Over a long time, this will cause damage to the electrostatic precipitator itself.

[0003] The patent application number "CN201520017078.4" records an "electrostatic precipitator, including one or more electric fields arranged along the gas flow direction. Each of the electric fields includes a plurality of power supply zones arranged along the gas flow direction. Each of the power supply zones includes: one or more anode plates for adsorbing negatively charged dust particles; one or more cathode wires for adsorbing positively charged dust particles; a power supply device, the positive pole of the power supply device is connected to the anode plate, and the negative pole of the power supply device is connected to the cathode wire; the power supply device supplies power to form an electric field between the anode plate and the cathode wire."

[0004] Based on the electrostatic precipitator, the above patent divides the electric field into multiple power supply zones and supplies power separately, reducing the electric field width of the electric field, being able to improve the uneven corona current phenomenon in a single electric field, and improving the dust removal efficiency.
