Movable pole plate on electric precipitator

Abstract

The invention discloses a movable pole plate on an electric precipitator. The movable pole plate comprises an anode plate assembly, an anode plate moving mechanism, an anode plate limiting mechanism and a transmission tensioning mechanism; the anode plate assembly comprises at least one anode plate; the anode plate is vertically arranged in a direction following the wind; the anode plate is of a plate frame type structure; inner and outer plate layers of the anode plate are fixed by adopting profile steel; the anode plate moving mechanism comprises a transmission chain and a chain wheel; the transmission chain is engaged with the circumferential wall of the chain wheel; the chain wheel is arranged at the upper and lower ends of the anode plate assembly; the anode plate limiting mechanism is provided with a guide groove type limiting mechanism; the transmission tensioning mechanism comprises a screw rod; the screw rod is provided with a screw rod push fixing point and a screw rod regulating device; and the screw rod push fixing point is arranged on a bottom beam of a precipitator box body. The movable pole plate on the electric precipitator disclosed by the invention can run for a long time without falling of the chain, does not affect the transmission of the anode plate, improves the discharging and dust removal efficiency of the precipitator and reduces the maintenance rate and the repair rate.

Description

technical field [0001] The invention relates to a mobile pole plate on an electrostatic precipitator, which belongs to the technical field of air pollution control, can be used for dust-containing flue gas treatment in the final electric field of an ordinary electrostatic precipitator, and is suitable for flue gas from power station boilers, industrial boilers, incinerators, etc. Gas dust removal field. Background technique [0002] Electrostatic precipitator is an industrial purification equipment that relies on electrostatic force to collect dust. The working principle of the traditional electrostatic precipitator is: high voltage from a high-voltage power supply is applied to the corona wire, the corona wire generates corona discharge, and forms an electric field; the dust in the flue gas flowing through the electric field is generated by the corona wire discharge charged ions; the charged dust is collected on the dust collecting plate under the action of the electric fi...

Problems solved by technology

[0005] Although the mobile plate technology has been widely recognized by the market and users, especially with the rise of the low-temperature electrostatic precipitator theory, the mobile plate technology is a key technology, but according to the feedback during use, the existing mobile plate electric It is common for the dust collector to drop the transmission chain during operation and the discharge performance is unstable, resulting in increased shutdown and maintenance rates.
