Agitated Nutsche Filter
Agitated Nutsche filter (ANF) is a filtration technique used with dyes, paints, fine chemical industries. Safety requirement and environmental concerns due to solvents evaporation lead to development of this type of filter wherein filtration under vacuum or pressure can be carried out in closed vessel .even solids can be discharged straightaway into drier.
Additional recommended knowledge
It consists of a dished vessel with a perforated plate. The entire vessel can be kept at desired temperature by having a limpet jacket through which heat transfer medium can be passed. The vessel can be made completely leak proof for vacuum or pressure service.
A multipurpose agitator is the unique feature of this system. The agitator performs the following operation by vertical movements and even in direction of rotation.
A power pack is a unit attached to the ANF’s agitator system. It consists of an oil tank on which a pump is provided for circulating high pressure oil through control valve system and to hydraulic cylinders. These cylinders are provided for vertical movement of the agitator. Operating pressure of oil various from 2 kg/cm² to 80 kg/cm² (200 kPa to 8 MPa).
ANF’s can be fabricated in materials like Stainless Steel., Mild Steel., and Mild Steel with rubber lining as per service requirements. Recently ANF’s have been fabricated out of PPFRP (PolyPropylene Fibre Reinforced Plastic).
1. Vacuum or pressure filtration possible. 2. Inert gas atmosphere can be maintained. 3. Very high solvent recovery. 4. Considerable saving in manpower 5. Solvents are in closed systems, so no toxic vapors are let off in the atmosphere. 6. Personal safety is maintained and heat transfer surfaces can be provided to maintain filtration temperature.
