Wet dust collector: the efficient choice for industrial dust removal
Jun 18,2025
Dust pollution control is crucial in industrial production. As a commonly used equipment, wet dust collectors utilize the interaction between water or other liquids and dusty gases to achieve efficient dust removal.
Working principle
After entering the wet dust collector, the dusty gas comes into full contact with the liquid (mostly water). Larger dust particles are captured and settled by collisions with water droplets due to inertia; Fine dust adheres to the surface of water droplets through diffusion, condenses into large particles, and is captured. For example, in a spray tower, the dusty gas passes through the water mist sprayed by the tower top nozzle, and the dust meets the water mist and is removed.
Significant advantages
1. Efficient dust removal: For dust particles ranging from 0.1 to 20 microns, the dust removal efficiency can reach over 90%, effectively purifying high concentration dust exhaust gases.
2. Wide adaptability: It can handle high temperature, high humidity, flammable and explosive gases, such as coal mines, chemical industries, etc., and can reduce the risk of fire and explosion.
3. Multifunctionality: Not only can it remove dust, but it can also absorb some gaseous pollutants. For example, when treating coal-fired waste gas, it can remove harmful gases such as sulfur dioxide and lower the temperature of the waste gas.
4. Simple structure: Compared to some dry dust collectors, it has a simple structure, occupies a small area, and is relatively easy to install, operate, and maintain.
application area
Widely used in industries such as mining, metallurgical smelting, chemical production, building materials manufacturing, and power generation. For example, in cement plants, it can be used for dust removal in kiln tail, grinding machine and other processes; The coal mining industry is used in underground mining, coal screening and other places to reduce the harm of dust to the environment and workers' health.
However, the operation of wet dust collectors will generate wastewater, which requires a supporting treatment system to prevent secondary pollution; In high humidity environments, performance may be affected. But with many advantages, it is still an ideal choice for industrial dust removal, helping enterprises achieve clean production.
