Comparison between spray dust removal and bag dust removal?

In the dust collector, water is sprayed into mist through the nozzle or through the tray and filler, so that the dusty gas fully contacts with the fluid. Due to the collision, interception and condensation between the dust particles and the liquid droplets, the dust particles fall with the liquid droplets. This kind of dust collector has simple structure, small resistance and convenient operation, and can handle gases with high dust concentration without causing blockage. Circulating water can be used in the spray dust collector until the particulate matter in the washing liquid reaches a fairly high level, thus greatly simplifying the water treatment equipment. Therefore, this kind of dust collector is still adopted by many enterprises. Its disadvantage is that the equipment volume is relatively large and the water consumption is relatively large, so the power consumption is relatively large and the water content of the removed dust is large. It is especially suitable for high-pressure cooling process, such as dust removal in coal-fired gas manufacturing.

Bag filter makes dusty gas pass through fiber fabric bag and transfers dust. Generally, it is named by the way of cleaning dust, and it is mainly divided into three types: mechanical vibration bag filter, atmospheric backwashing bag filter and pulse jet bag filter. It has high classification dust removal efficiency for submicron fine dust and wide gas treatment range. Uses: widely used in metallurgy, mining, cement, thermal power plant, building materials, casting, chemical industry, tobacco, asphalt mixer, grain, mechanical processing and boiler dust removal. Generally used in low-pressure and low-power processes, the "dust" to be removed cannot contain moisture.
