Abstract
The object of the present invention is an equipment provided with a fabric deodorization loop and a fabric cooling loop, both of which are connected in closed loop to the container into which the fabric is delivered, and an activated charcoal cooling loop, it too being a closed loop, connected to the filters of the deodorization loop.
Claims7
A textile processing apparatus for continuously deodorizing fabric and extracting and recovering solvents from fabric consisting essentially of
- an air distribution element having ports to permit the entry and exit of fabric,
- a main fan having its intake connected to said air distribution element and its discharge connected to at least two activated charcoal filtering elements, each activated charcoal filtering element comprising filtering materials including activated charcoal and upstream of said filtering materials a steam injection element, each activated charcoal filtering element further including at least two valved intake ports, I.sub.a and I.sub.b, and at least three valved discharge ports D.sub.a, D.sub.b, and D.sub.c,
- wherein the discharge of said main fan is connected at valved intake ports I.sub.a, and said valved discharge ports D.sub.a are connected to said air distribution element, forming a closed main fan circulation loop from said air distribution element through the main fan, through the at least two activated charcoal filtering elements and back to said air distribution element,
- wherein said valved discharge ports D.sub.b are connected to the intake of a secondary fan, the discharge of which is connected to the valved intake ports I.sub.b of said at least two activated charcoal filtering elements, forming a closed secondary fan circulation loop from said secondary fan through said at least two activated charcoal filtering elements and back to said secondary fan,
- wherein said valved discharge ports D.sub.c provide a solvent recovery vent from said activated charcoal filtering elements to a solvent recovery apparatus,
- which valves of said valved intake and discharge ports are independently operable so as to permit each activated charcoal filtering element to be connected, independently, to the closed main fan circulation loop, the closed secondary fan circulation loop, or the solvent recovery vent.
