It is mainly composed of screen plate, water pipe, water tip plate (also known as defoamer), water seal blowdown valve and inlet and outlet. Dusty smoke enters the cylinder from the lower part of the cylinder, the air flow rises sharply and reduces the settling velocity. The coarse dust is thrown out under the action of inertia force, and collides with the falling water on the porous sieve plate. It is discharged by water from Mongolia. The finer dust rises with the airflow and passes through the porous screen to report time, and the water layer on the sieve plate is blown into a turbulent, boiling bubble layer. The contact area between gas and water drop is increased, so most of the dust is washed down by water. Dust is discharged from the bottom cone to the sedimentation tank by water seal with sewage. The purified flue gas is discharged through the upper water baffle.
