Whirlwind water wash static dedusting and purifying device
Technical field
The present invention relates to a kind of air cleaning unit, especially a kind of whirlwind water wash static dedusting and purifying device.
Background technique
With the rapid development of our country's economy and the quickening of process of industrialization, the problem of environmental pollution in China is also increasingly
Seriously, the especially frequent generation of China's haze weather in recent years, the atmosphere pollution situation in China is very serious, produces in industrial production
Raw a large amount of flue dust enters in atmosphere, and therefore, China limits flue gas must could discharge atmosphere after dedusting is up to standard;Deduster
The dust in flue gas can be effectively reduced, deduster is applied in the factory than wide, and factory generates largely in process of production
Flue gas, especially in the enterprise of the high pollution industries such as power plant, the dust content in flue gas is higher, and flue gas emission is right into environment
The damage ratio of atmosphere is more serious, could discharge after needing to be effectively treated flue gas, and deduster is a kind of essential dirt
Treatment facility is contaminated, mainly has bag filter, pulse dust collector, bag filter, rotation using more extensive deduster at present
Wind deduster, electrostatic precipitator and wet dedusting etc., dustiness is few in the flue gas after dedusting, and flue gas emission is not caused into atmosphere
Atmosphere pollution, it is welcomed by the people;Currently, electrostatic precipitator is using relatively broad, but electrostatic removes in dedusting work
