The circular bag frame is the rib of the filter bag, which is lightweight, easy to install and maintain. The quality of the frame directly affects the filtering state and service life of the filter bag. The skeleton is the rib of the filter bag, which should be lightweight, easy to install and maintain. The quality of the skeleton directly affects the filtering state and service life of the filter bag. Our company has introduced advanced skeleton manufacturing equipment and uses high-frequency welding machines to weld the skeleton into shape in one go. Use iron wire or stainless steel wire with sufficient strength and rigidity. Treatment methods such as galvanizing, spray coating, and organic silicon plating. The skeleton treated with organic silicon technology by our company can completely replace stainless steel skeleton, which can greatly reduce the maintenance cost of equipment. And every frame manufactured can meet the requirements of lightness, smoothness, and straightness. The annual production capacity is 2 million pieces, which can meet the urgent supply needs of customers.

The working principle of the circular bag frame: The dusty airflow enters the Venturi through the inlet flue, and is evenly sprayed with water at the entrance of the throat. Due to the high-speed movement of the flue gas, the sprayed water is melted into fine water mist, which moistens the ash in the flue gas. In this process, the ash in the flue gas is wetted, increasing its weight and facilitating centrifugal separation. In the high-speed floc flow state, due to the large difference between water droplets and dust particles, their velocity difference is also large. In this way, the collision and condensation of ash particles and water droplets occur, especially for fine dust particles that can be dissolved by water mist, which fully prepares for the separation of ash particles and then enters the cylinder. The cylinder is a circular cylinder, and water enters the cylinder from the upper water injection tank of the dust collector, forming a layer of water film on the inner wall of the entire cylinder to flow from top to bottom. The flue gas enters the cylinder from the lower part of the cylinder tangentially and rotates upward inside the cylinder. The dusty gas always rubs against the water film on the inner wall of the cylinder under the action of centrifugal force, so that the dusty gas is wetted by the water film. The dust particles flow with the water to the bottom of the dust collector and are discharged through the overflow hole. The bottom of the cylinder is sealed and equipped with a water seal groove to prevent the flue gas from leaking out from the bottom. There are cleaning holes for easy cleaning of the bottom of the cylinder. After dust removal, the wastewater is discharged from the bottom overflow hole into the sedimentation tank, where it is neutralized and recycled. The purified gas is drawn out through the upper conical part of the cylinder to achieve the purpose of dust removal. Adding alkaline water to the circulation pool of the dust removal equipment can achieve the effect of a desulfurization and dust collector.
