These are the bag Filter that are cleaned by using the flowing of air to the backwards through the cloths for the purpose of collecting the dust. It is known by reverse air filter bags because of only its work that is allowing the backward or reverse air to the cloths for removing the dust.
In the liquid application these bag filter is used for straining to remove the major tiny particles from the bag filter. These bag filters are having the simple arrangement of having a single bag attached with the pipes.
In reverse air type filter bags, the bags are fastened at the bottom of the filter bag. These bags are then adjusted by the hanger at the top of the frame. There are rings which are also known as supported rings which allows the bag to create a open space at top of it. The valve use in that type of bags allows to get the incoming air and also allows to get free it with a continuous manner. The dirty fir flow or enters into the bag filter and then clean air get rid of from the bag filter with the help of these valve.
COMPONENTS USED IN REVERSE AIR TYPE FILTER BAGS
Bag Supported Rings
TECHNICAL ASPECTS OF REVERSE AIR TYPE FILTER BAGS
Velocity of the air in the reverse air type filter bags is about to .04m/sec.
Air Filtration Pressure in the bag is lies between 0 to 800 k pa.
If we want to know about the collector loading efficiency then we used this formula-
[(inlet loading – outlet loading) x 100]/ Inlet Loading
WORKING OF REVERSE TYPE AIR BAGS
Reverse air type filter bags are accomplish for continuous process. The bags are cleaned by allowing the air in to the dust collector in reverse direction with some pressure and velocity. This pressure makes the bag to collapse the particles and causing the air to top into the bottom. At the end of the cleaning cycle, reverse airflow is discontinued, and the compartment returned in to the main stream. In this manner the reverse type of dust collector, collects the air particles in the air bag.
There are wide range of fabrics in the filter bags
Wide range of pour sizes are also available here
It has high tensile strength of its rings
Have a great surface area
