Polar plate

Abstract

The invention discloses a polar plate. The polar plate comprises an anode plate integration, an anode plate moving mechanism, an anode plate limiting mechanism and a transmission tensioning mechanism,wherein the anode plate integration comprises at least one anode plate, the anode plate is arranged in a vertical downwind direction, the anode plate is a plate-frame type structure, and the inner and outer plate layers of the anode plate are fixed by profile steel; the anode plate moving mechanism comprises a transmission chain and chain wheels, the transmission chain is engaged on the peripheral wall of the chain wheels, and the chain wheels are arranged at the upper and lower ends of the anode plate integration; a guide slot type limiting mechanism is arranged on the anode plate limiting mechanism; and the transmission tensioning mechanism comprises a screw rod, the screw rod is provided with a screw rod pushing fixed point and a screw rod adjusting device, and the screw rod pushing fixed point is arranged on a bottom beam of a dust collector box body. The polar plate provided by the invention can run for a long time without dropping the chain, does not affect the transmission of the anode plate, improves the efficiency of discharge and dust removal of a dust collector, and reduces the maintenance and repair rate.

Description

technical field [0001] The invention relates to a pole plate, belonging to the technical field of air pollution control, which can be used for dust-laden flue gas treatment in the final electric field of ordinary electrostatic precipitators, and is suitable for flue gas dust removal fields of power station boilers, industrial boilers, incinerators, and the like. 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 field force; the dust collected on the dust c...

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.
