Working principle of boiler dust collector

The flue gas enters the Venturi through the inlet duct and is evenly sprayed with water at the throat entrance. Due to the high-speed movement of the flue gas, the sprayed water is melted into small water mist to wet the ash material in the flue gas. In this way, the ash material collides and condenses with the water droplets, especially the small diameter dust material can be dissolved by the water mist. To achieve good sales, dust removal and desulfurization are necessary for the separation of ash materials. After that, the flue gas enters the cylinder at a suitable speed to reduce the temperature and continues to impact the lime water in the pool. The dust and SO2 in the flue gas react with the lime water in the pool to form sulfates, which sink to the bottom of the water under the action of inertia, gravity, adhesion, and cohesion to complete the excellent secondary desulfurization process. The water droplets, water mist, and washed flue gas stirred up by the flue gas are lifted apart by the fan's gravity, allowing the flue gas to fully react with the lime water. Then, the actual main water is separated through the impeller dehydrator, and the water flows into the water tank through the drainage pipe, completing the third dust removal and desulfurization of the flue gas. The purified gas is discharged into the atmosphere through the fan.
