Wet Spray Cyclone Integrated Air Purification Device

technical field

The utility model relates to an industrial air purification device, in particular to a wet spray and swirl integrated air purification device used for collecting particulate matter in industrial production.

Background technique

With the rapid development of the economy, the emission of particulate pollutants from chemical, mechanical processing, casting and other industrial production is increasing, resulting in the deteriorating quality of the atmospheric environment, which has posed a huge threat to the ecological environment and human health.

Aiming at the problem of particle pollution, dust removal technologies in industrial production can be divided into two categories: ①Dry dust collector: gravity settling chamber, inertial dust collector, electrostatic precipitator, bag filter and cyclone separator, etc.; ②Wet dust removal: spray shower tower, impact dust collector, Venturi scrubber and water film dust collector, etc. Among them, electrostatic precipitator, bag filter and cyclone separator are the most widely used, but these kinds of precipitators have certain shortcomings and deficiencies.

The electrostatic precipitator equipment is relatively complex, occupies a large area, and requires a high level of equipment deployment, installation, and maintenance management; and has a certain selectivity for dust, which cannot achieve high purification efficiency for all dust. The ability of the bag filter to withstand the temperature is limited. When purifying the flue gas with a higher temperature, measures must be taken to reduce the temperature of the flue gas; when the flue gas contains more water or the dust carried by it has strong hygroscopicity, it often causes the filter bag to stick. , Block the filter material; in addition, the cloth bag needs to be replaced regularly, which increases the cost. The cyclone separator has simple structure, convenient operation, high temperature resistance, long service life, high separation efficiency and low resistance, so it is the most widely used in purification equipment; but its efficiency for capturing fine particles (particle size less than 5 μm) is not high .
