Transverse polar plate bipolar static agglomeration dedusting device and dedusting method thereof

Abstract

The invention discloses a transverse polar plate bipolar static agglomeration dedusting device and a dedusting method thereof, which solve the problem that the conventional dedusting device is complex in structure and relatively poor in dedusting effect. The invention adopts the technical scheme that the transverse polar plate bipolar static agglomeration dedusting device comprises a deduster casing as well as an air inlet pipe and an air outlet located at the two ends of the deduster casing; a plurality of cathode frameworks and a plurality of anode frameworks are vertically, alternately and uniformly arranged in the deduster casing in the direction of an airflow; a plurality of cathode plates and a plurality of cathode coronal lines are alternately and uniformly distributed on the cathode frameworks in the vertical direction, and a plurality of anode plates and a plurality of anode coronal lines are alternately and uniformly arranged on the anode frameworks; moreover, the cathode coronal lines are corresponding to the central lines of the adjacent anode plates in the direction of the airflow, and the anode coronal lines are corresponding to the central lines of the adjacent cathode plates in the direction of the airflow; the cathode frameworks are connected with the high-voltage output ends of a high-voltage DC power supply via a high-voltage cable, and the anode frameworks are connected with the grounding pole of the high-voltage DC power supply via a grounding cable. The transverse polar plate bipolar static agglomeration dedusting device is simple in structure, small in size, simple and convenient to operate, outstanding in the dust collection effect of the reverse sides of the transverse polar plates, small in reentrainment of dust, and has the effect of static agglomeration dedusting.

Description

technical field [0001] The invention relates to an electrostatic dedusting device and method in the field of smoke and dust purification, in particular to a bipolar electrostatic coagulation and dedusting device and a dedusting method for a horizontal plate. Background technique [0002] Horizontal plate electrostatic precipitator, because the direction of the dust collector plate and the airflow direction are perpendicular to each other, the direction of the electric force line in the electric field is consistent with the direction of the airflow, and the electric field force on the charged particles is in the same direction as its own inertial force. Therefore, when the particles are captured, there is not only the electrostatic effect, but also the inertial separation effect of the airflow, which speeds up the approaching speed of the charged particles to the dust collecting plate and improves the dust removal efficiency. [0003] In the 1960s, West Germany and the United...

AI Technical Summary

Problems solved by technology

Although the windward side (front) of the horizontal plate has better dust collection effect, the leeward side of the horizontal plate has little dust collection

[0010] 2. The secondary dust problem is more prominent

The air flow scours the front of the horizontal plate, causing some dust deposited on the plate to blow up again and return to the air flow, which weakens the dust removal effect of the horizontal plate electrostatic precipitator

[0011] 3. No electrostatic condensation effect

Since the charge of the dust in the existing horizontal plate electrostatic precipitator is unipolar, the fine dust repels each other and cannot be condensed into larger particles and then captured
