Advantages: simple construction, light weight, and higher dust removal efficiency compared to packed towers. Disadvantages: high gas resistance; lower operating flexibility compared to packed towers.
Advantages: high efficiency; Disadvantages: large pressure drop
Advantages: simple structure, light weight, and higher dust removal efficiency compared to packed towers. Disadvantages: High gas resistance; lower operating flexibility compared to packed towers.
Advantages
(1) When consuming the same amount of energy, the dust removal efficiency of this dust collector is higher.
(2) The dust collector can simultaneously purify harmful gases; it is suitable for treating flue gas at high temperatures and humidity, as well as dust with high adhesiveness. (3) Suitable for treating combustible dusty gases. (4) The dust collector has a simple structure, occupies little space, and requires low initial investment. (5) Suitable for situations where the production process itself has a water treatment facility. Disadvantages
(1) The dust-containing wastewater and sludge discharged from the dust collector may cause secondary pollution and thus require treatment. (2) Not applicable to hydrophobic and hydraulic dust. (3) It is difficult to use in places where water sources are scarce. (4) In cold regions, prevent freezing in winter. (5) Not applicable to gases containing hydrophobic dust, or dust that is prone to spontaneous combustion or scaling when exposed to water.
