Abstract

The invention relates to a flue embedded acoustic-electric joint condenser. At present, existing acoustic-electric joint condensers cannot achieve acoustic coagulation effects. The flue embedded acoustic-electric joint condenser is characterized by comprising a positive high-voltage power supply, a negative high-voltage power supply, a plurality of rows of positive discharge electrode wire groups, a plurality of rows of negative discharge electrode wire groups, a plurality of rows of grounding electrode wire groups and a metal module, the metal module is provided with a metal top cover and a metal bottom plate, a flue gas channel is formed between the metal top cover and the metal bottom plate, each row of positive discharge electrode wire groups includes a plurality of positive discharge electrode wires, each row of negative discharge electrode wire groups includes a plurality of negative discharge electrode wires, each row of grounding electrode wire groups includes a plurality of grounding electrode wires, one row of grounding electrode wire groups is arranged between one row of positive discharge electrode wire groups and one row of negative discharge electrode wire groups which are adjacent, a positive discharge channel is formed between one row of positive discharge electrode wire groups and one row of grounding electrode wire groups which are adjacent, and a negative discharge channel is formed between one row of negative discharge electrode wire groups and one row of grounding electrode wire groups which are adjacent. The flue embedded acoustic-electric joint condenser is small in occupied space and can achieve the acoustic coagulation effects.

Description

technical field

[0001] The invention relates to an acoustic-electric combined coalescer, in particular to a flue-embedded acoustic-electric combined coalescer, which is used to charge the dust in the dusty flue gas in the flue to form a charged Dust particles, and make the charged dust particles agglomerate to form large particles, mainly used to treat the dusty flue gas in the flue of coal-fired power plants. Background technique

[0002] Electrostatic precipitator is a commonly used dust removal equipment in coal-fired thermal power plants. Although the electrostatic precipitator can remove most of the dust, the removal rate of PM10 and PM2.5 is very low. The main reason is that the particles are too small to be easily charged, and the electric Vibrating dust removal by the dust collector is likely to cause secondary dust, resulting in secondary pollution. In this regard, scholars at home and abroad have conducted a lot of research and made certain improvements to electro...
