The working principle of the bag filter . During operation , the dust- containing gas is evenly distributed to the filter bag chamber of each unit through the air volume control valve of the bag filter's intake pipe. Due to the actual expansion of the air flow section or the role of the baffle, a part of the air flow Large particles of dust fall into the ash bucket due to inertia. The small particles of dust are blocked outside the filter bag by screening, inertia, adhesion, diffusion and static electricity. The gas purification trust enters the bag and is collected in a clean air chamber and exhausted The tube is discharged. Through continuous filtration, dust particles gradually form a dust layer on the surface of the filter bag under the action of adhesion and retention.
The working principle of the bag filter : As the dust on the surface of the bag filter continues to increase, the resistance of the filter bag increases. When the pressure difference in the filter bag chamber reaches a set value or a set time, the controller sends a signal, The poppet valve closes the exhaust port of the filter bag chamber of the unit, and makes the filter bag chamber offline. At this time, the compressed air is sprayed from the nozzle on the injection pipe by the airbag through the pulse valve into the filter bag of the unit's filter bag chamber, and is sprayed in groups. After completion, the poppet valve is opened, and the filter bag is restored to the filtering state. Similarly, the filter bag room of the other unit is also controlled by the program controller to perform the spray cycle in order to achieve the purpose of dust removal. Finally, due to the expansion of the filter bag and the reverse acceleration, The dust falling from the ash bucket is sent away by the ash conveying device.
What inspections need to be performed on bag dust collectors in daily life?
When using a bag filter, you must pay attention to him and carry out a certain quality inspection, especially after using it for a period of time, because it will absorb dust and may damage some of the components inside. We must check in time to avoid damage affecting the use Bag filter parts. We also need to regularly check the pressure condition of the bag filter to see if it is blocked? If it is necessary to clean it in time, it must be cleaned in time, otherwise the dust removal efficiency will decrease and some functions will decrease.
