Abstract
The invention discloses a fine particle rotational flow type electric agglomeration dust removing and collecting device. The device is arranged at the front portion of an electric precipitator. Fine particles are carried by airflow to enter a cylindrical shell in the tangential direction. Friction bars and arista electrodes are arranged on the inner wall face of the shell, the particles collide with and make contact with the friction bars to rub electrical charges in the gradual downward rotational flow type moving process, and the arista electrodes intensify the electrical charges under the action of corona. The charged particles enter a pipeline connected through at least one pair of Venturi tubes. High-voltage electrode plates opposite in polarity are arranged on the two sides of the Venturi tubes, consequently, the particles generate collision and coagulation through the action of electric field force in the opposite directions, and the particles are conveyed into the electric precipitator through the pipeline to be collected and subjected to dust removing. The problem that the electrical charges of the fine particles are not sufficient is solved. The collision frequency in the particle coagulation process is increased, particle aggregates with the large granularity can be obtained, the dust removing efficiency of the electric precipitator is improved, the concentration of the fine particles in air is reduced, and the environment pollution is reduced.
