Reverse Bag House is an air pollution control device used for the removal of fine particulate matter from industrial gas streams. It works by reversing the flow of air in the baghouse, causing the dust and particles to fall off the bags and into a hopper or bin.
The Reverse Bag House operates on the same principle as a regular baghouse, with the exception that the air flow is reversed periodically to shake off the dust accumulated on the bags. This helps to ensure that the bags remain clean and free of clogs, which can negatively impact the efficiency of the system.
The Reverse Bag House typically consists of a series of filter bags, which are suspended vertically inside a housing unit. The bags are made from various materials depending on the application, including woven and felted fabrics. As the industrial gas stream enters the baghouse, the particulate matter is trapped on the surface of the bags, while the cleaned air is discharged out the top of the unit.
Periodically, the air flow is reversed, causing the dust and particles to fall off the bags and into a hopper or bin for disposal. The Reverse Bag House can be equipped with a range of control systems to optimize performance, including differential pressure sensors, temperature sensors, and timers.
Reverse Bag Houses are used in a wide range of industries, including cement, mining, and power generation, to control emissions of particulate matter. They are particularly effective at capturing fine particles that are difficult to remove using other technologies.
Overall, the Reverse Bag House is a highly effective and efficient air pollution control device that can help industries meet regulatory requirements and improve air quality.
