Novel electrical dust collector

Abstract

The invention discloses a novel electrical dust collector. The novel electrical dust collector comprises a housing, multiple lines of polar plate rows and multiple lines of electric corona lines, wherein one side of the housing is provided with a horn-shaped air inlet, and the other side of the housing is provided with a horn-shaped air outlet; the lower part of the housing is provided with an ash hopper; the electric corona lines and the polar plate rows are alternately and transversely arranged inside the housing along the air flow direction; each polar plate row is formed by mutually connecting a plurality of polar plates with inverted-V-shaped cross sections through the end parts of two arms; each polar plate with the inverted-V-shaped cross section is fixedly provided with a plurality of metal dust arrester plates on the two arms of each polar plate at intervals so as to form a shelter-shaped structure, and an included angle between each metal dust arrester plate and the air flow direction is 45-90 degrees; the polar plate rows are earthed, and the electric corona lines are connected with a positive high voltage power supply or a negative high voltage power supply; and the upper parts of the polar plate rows and the electric corona lines are connected with vibrating mechanism. The novel electrical dust collector effectively improves the dust collection efficiency, particularly the collection ability of PM2.5 superfine dust, improves the vibration dust cleaning efficiency, prevents the secondary dust blowing, and can meet the high emission requirement.

Problems solved by technology

The main problems of this traditional electrostatic precipitator are: first, in order to ensure that the electrode spacing is not affected during rapping, the anode plate must maintain sufficient rigidity, and multiple plates must be connected into one; The vibration frequency is low, and it is difficult to thoroughly clean the dust by vibrating, especially the sticky fine dust and high specific resistance dust are more difficult to remove, and the effect of vibrating to clean the dust is poor; the second is due to the setting of the corona wire and the anode plate and the direction of the airflow Parallel, the dust detached from the corona wire and the anode plate during mechanical rapping is easily taken away by the airflow, resulting in secondary dust, and instantaneous excessive emissions; third, some PM2.5 fine dust is light in weight and weak in charging capacity. Traditional electrostatic precipitators are difficult to capture, so these PM2.5 fine dusts are easy to escape with the airflow and become the "culprit" of haze weather, which also makes it difficult for this traditional electrostatic precipitator to meet the existing emission standards
