Fresh Air, Exhaust Air & Return Air Dampers
The function of the damper is to adjust the air volume blown / sucked by the axial fans so that the desired room conditions are maintained. The Dampers are generally made of Aluminum Aerofoil profiles or using GI sheets.
The function of the axial fans is to blow / suck the air into / from the departments so that the desired number of air changes is maintained.
Air Straitening Louvers
The function of the air straightening louvers is to straighten the air blown / reduce the air turbulence created, by the axial fans before entering the air washer chamber.
The function of the air washer is to impregnate enough moisture to the fresh air / re-circulated air before being supplied into the department by spraying water / high pressure fog system.
The function of the mist eliminator is to eliminate excess amount of water carried by the air passing through the air washer chamber before being fed into the department.
Supply Duct & Diffuser
The function of the supply duct and diffusers is to diffuse humid air evenly to the entire area of the department.
Grills & Exhaust Trenches
The function of the grills is to suck the heat produced by working of the machines along with fly liberated in the spinning process from the department through suitable underground trenches.
Exhaust Air Filter
The types of Exhaust air filters are:
- “V” Filter (VF)
- Disc Filter (DF)
- Rotary Drum Filter (RDF)
- Stationary Drum Filter (SDF)
- Multi-drum Filter (MDF)
“V” Filter is fitted in the exhaust air filter room and generally has nylon / SS mesh. The waste generated in the spinning process is collected on the wire mesh and the same has to be manually cleaned periodically.
Disc Filter is fitted in the exhaust air filter room and generally has SS mesh fitted on a round disc with a nozzle arrangement and transport fan so that the accumulated waste on the mesh is removed continuously..
Rotary Drum Filter
Rotary drum filter has rotating drum fabricated of punched sheets and the punched sheet is covered by Filter media to extract the waste and fine dust which is sucked from the department. The dust deposited on the filter media is continuously collected by a set of traversing nozzles.
Stationary Drum Filter
The stationary drum filter has round flange on suitable frame work and can be bolted directly to a wall opening / prefabricated PUF panel enclosure. The dust laden air from the department flows from the inside to the outside through the filter media. This means that the air inside the filter room is clean. A set of rotating and traversing suction nozzles on the inside of the filter media drum continuously sucks the dust and short fibers from the filter media.
Multi Drum Filter
The multi drum filter has a set of drums arranged concentrically in suitable frame work. The filler media is fixed between the adjacent drums and so on so that the filter media takes a cylindrical shape. A set of rotating and traversing suction nozzles clean the filter media continuously by sucking the dust and fly liberated in the spinning process from the filter media.
Air Tight Doors
Air tight doors are provided in the supply / exhaust air plants for avoiding mix up of humid air with atmospheric air and for manual entry for maintenance activities in the plant.
