▪️ Bag filter is an air purification system that is used to remove suspended particles from the gas stream. In asphalt factories, this system is used to control and reduce pollution caused by small particles such as soot and dust at the factory exit.
How Bag Filter Functions in Asphalt Factory
✔️ particle absorption: Air containing suspended particles enters the filter bag from the asphalt plant. These particles stick to the fibers of the filter bags and are separated from the air flow. ✔️Cleaning the bags: Periodically, the filter bags are cleaned with a pulse of compressed air to remove the collected particles from them. and be directed to the collection tank. ✔️Clean air exit: Purified and particle-free air exits from the top of the filter bag.
The Benefits of Using Bag Filter in Asphalt Factory
✔️ Reducing air pollution: The filter bag effectively separates suspended particles from the exhaust air and prevents them from being released into the environment.
✔️ Increasing the air quality around Factory: By reducing air pollution, the environmental conditions around the factory will improve. b>✔️High efficiency: Bag filters are able to remove very small particles with high efficiency.
Filter Bag Restrictions for Fat Control
✔️ Design for solid particles: Bag filters are designed mainly to remove solid particles and are less effective for separating grease.
✔️ Pore blockage: Grease can They can easily block the pores of the filter bags and reduce the efficiency of the system. ✔️High temperature: In high temperature environments, such as asphalt factories, fats may evaporate and enter the bag as vapor. be filtered, in which case they cannot be removed with this system.
To control the fat in the output of the asphalt factory, you can use other methods such as:
✔️Fat separator systems: These systems are based on physical principles such as sedimentation, Flotation and centrifuge are used to separate the fat from the outflow. ✔️Biological purification: Using bacteria to break down fats. chemical to break and decompose fats.
Conclusion:
▪️ Bag filter is an effective tool to control suspended particles at the asphalt plant outlet, but it is not enough to control fat alone. To achieve the best result, it is better to use a combination of different methods. Choosing the right method depends on the type and amount of pollutants in the output stream. Important note: To choose and design the right filtration system, it is better to consult with the experts of Asman Blue Filter Company. .
