Description

Efficient rotary closed type electrostatic dust collector
Technical Field
The utility model relates to a dust collector technical field specifically is a rotatory closed electrostatic precipitator of efficient.
Background
The electric dust collector has the advantages of large flue gas treatment capacity, large allowable temperature, high dust removal efficiency, small pressure loss resistance, convenient operation and control, low operation and maintenance cost and the like, and is widely applied to the field of flue gas dust removal of coal-fired boilers. Therefore, the electric dust collector is a necessary corollary equipment of a thermal power plant, and has the function of removing particle smoke dust in smoke discharged by a fuel stove or a fuel oil boiler, thereby greatly reducing the smoke dust discharged into the atmosphere, and being important environment-friendly equipment for improving environmental pollution and air quality.
It uses the exhaust pipe or closed cover of production equipment as polar plate, and arranges discharge electrode in the cover or pipe, and connects with high-voltage power supply to form electric field. When the dust-containing gas passes through the electric field, the dust is gathered on the cover or the pipe wall under the action of the electric field force, and the purified gas is discharged through the exhaust pipe. The ash removal is realized by manual vibration or self-weight falling.
However, with the increasing national environmental protection requirements, the emission requirements for the flue gas of the coal-fired boiler are increasingly strict, and the flue gas and dust emission of the coal-fired boiler are definitely required to reach the ultra-clean emission standard. The inherent defect that the concentration of the flue gas and the dust exceeds the standard is undoubtedly exposed because the electric dust collector carries out dust re-raising by the flue gas due to the existence of the rapping dust-removing.
The reason for generating the dust again is mainly as follows: firstly, dust caused by vibration; secondly, airflow dust caused by flow channeling and air leakage; and thirdly, electrical dust caused by large current and strong corona. If the dust occurs in the electric field at the front stage, the electric field at the rear stage can adsorb and collect the dust again, but if the dust occurs in the electric field at the last stage, the dust can only be discharged because the dust cannot be collected again. Generally, the dust caused by vibration accounts for more than 80% of all the dust.
