SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned deficiencies of the prior art, the present invention provides a magnetoelectric vertical field coagulation device capable of improving the coagulation efficiency of charged particles of different polarities.
In order to achieve the purpose, the utility model provides a magnetoelectric vertical field coagulation device which comprises a channel for conveying dusty airflow and a plurality of air channels uniformly arranged along the height direction and the width direction of the channel, wherein each air channel comprises two side walls respectively consisting of a high-voltage polar plate and a ground polar plate, and a top wall and a bottom wall respectively consisting of two permanent magnet plates, the corresponding sides between the two permanent magnet plates are opposite magnetic poles, and the direction of an electric field formed between the high-voltage polar plate and the ground polar plate is vertical to the direction of a magnetic field formed between the two permanent magnet plates.

On the other hand, under the combined action of the Lorentz force and the electric field force, the particles are in irregular curvilinear motion, the irregular curvilinear motion increases the retention time of the particles in an air passage, and increases the collision probability among charged particles with different polarities, so that the coagulation of the particles is further promoted.
