The wet dust removal and desulfurizer is in the wet dust precipitator.Water bath precipitator is the most popular one with simple structure, low cost and easy maintenance and management.
Dust removal mechanism:
Trapped and settled by water, the flue gas enters the water surface of the nozzle, and the coarse particle dust is caused by inertial collision.Is the impulse stage;High-speed jet from nozzle crevices stimulates a large number of bubbles and water bubbles along the cylinder, which strengthens the film formation and condensation of soot. Bubbles occur and break from time to time, resulting in strong swirl disturbance. Soot is washed and absorbed from time to time and settles on the edge of the cylinder, forming a foam stage.The airflow passes through the foam layer and enters the water spray and fog drop area, which is washed by the shower, and the flue gas is further absorbed and purified.When the flue gas containing certain fog droplets rises to the conical dewatering plate of the first stage, it is intercepted and flows down the wall, which has the function of both dewatering and dusting in the fourth stage. The whole process of dusting and desulfurization is a unified water-liquid absorbent with abundant SO2 gas.
Principles to be followed:
No forced shutdown due to aircraft failure, 1 safe and reliable.And cause production loss.Adapt to boiler unit maintenance period.2 long maintenance cycle.Low water and electricity consumption.3. Economy and energy conservation.4 can be used together with desulfurization.
