Skeleton is a dust bag in the ribs, it should be lightweight, easy to install and maintain, the framework directly affects the quality of the state and bag filter life. Its working principle is: the flue dust into the air through the importation of Venturi, the throat of the entrance was sprayed into the water, due to smoke high-speed movement, so the water is injected into the melt into tiny mist, moist smoke gray material. 
 The dust mainly by the Venturi skeleton, the main cylinder, the upper injection tank, the lower part of the overflow hole, cleaning hole and so on. 
 After the dust discharge wastewater from the bottom of the overflow hole into the sedimentation tank, settling in and, recycling. Purified gas through the cylinder leads to the upper part of the cone, so as to achieve the purpose of dust. Equipment such as dust cycle in the pool by adding alkaline water, can play a desulfurization dust effect. 
 In this process, the flue gas ash material is wet, the weight of it and help to increase the centrifugal separation, flocculation was in high flow state, due to the large difference between water droplets and dust particles, their speed difference as well. In this way, dust particles and water droplets condensed on the collision occurred, in particular, small dust particles can be spray water-soluble materials, which are material for the separation of ash fully prepared, then into the cylinder. 
 Cylinder is a circular cylinder, water from the filter tank injection into the upper barrel, so that the entire cylinder wall to form a water film from the top down flow of gas from the cylinder bottom cut into the cylinder body rotation rise, dusty gas under the centrifugal force is always the water film with the cylinder body wall friction, so that the gas is water film wetting the dust, dust to dust the bottom with water, discharged from the overflow hole in the bottom of the tube and back cover with water seal groove to prevent gas leakage from the bottom, there is clear bottom of the tube holes for easy clean up.
