APPARATUS FOR TREATMENT OF GASES Filed July 51, 1939 INVENTOR C/yae L. h'uns/cker ATTORNEY Patented Sept. 9, 194 1 UNE TE TES PATENT ()FFHCE 1 Claim.
This invention relates generally to apparatus for the treatment of gaseous mediums, and is particularly applicable for the removal of moisture from air.
It is an object of the invention to provide compact apparatus of the above character which will afford efiicient removal of moisture from air and without occasioning too much resistance to air flow through the same.
A further object of the invention is to provide apparatus of the above character which can be readily regenerated by application of heat, without material deterioration.
Additional objects of the invention will appear from the following description in which the preferred embodiments of the invention have been set forth in detail in conjunction with the accompanying drawing.
Referring to the drawing:
Fig. 1 is a side elevational view, partly in crosssecticn, illustrating apparatus incorporating the present invention.
Figure 2 is a side elevational view of the structure shown in Figure 1, partly in cross section.
Figure 3 is an enlarged detail showing the manner in which the moisture-absorbing elements of Figures 1 and 2 are formed and are carried by the supporting structure.
Figure 4 is a cross sectional view taken along the line i i of Figure 3.
The apparatus as illustrated in Figs. 1 to 3 inclusive of the drawing consists of a conduit H), which can be of any convenient contour, and which is adapted to convey a stream of air or other gas to be treated. Within this conduit there is an assembly designated generally at I which includes a plurality of elements with which the air contacts for the purpose of moisture absorption. I
The supporting frame H is adapted for insertion in the conduit l and provides a mounting for a plurality of rope-like elements I8. To support each of these elements, I have shown a wire I9 wound h-elicoidally about the same, with the extended end ZEI of the wire serving to attach the element to the members 2| of the supporting frame. Instead of having these elements extend in parallel relationship, they are preferably inclined and crisscrossed as illustrated in Figures 1 and 2, in order to form tortuous passages to flow of air, thus more effectively causing contact of the air with the surfaces oi the elements.
The elements I8 are preferably of asbestos fiber, or so-called asbestos fiberboard, carrying a moisture absorbing chemical like calcium chloride having the property of deliquescence. Such a chemical can be readily incorporated in the asbestos as by impregnating the asbestos in a hot concentrated solution of the chemical. Calcium chloride will corrode most metals and metal alloys with which it comes into contact. To avoid such corrosion I prefer to make the metal parts of Mono metal, including particularly the parts of the frame H.
The apparatus described above is capable of efiiciently absorbing moisture from air. Air caused to pass through the conduit in fiows through the tortuous passages and is thus brought into intimate contact with the surfaces of the asbestos and with the calcium chloride. When efiiciency has been impaired due to the amount of moisture carried by the calcium chloride, the apparatus can be readily recycled or regenerated by application of heat. The asbestos fiber has sufficient absorbing capacity to hold the calcium chloride or other moisture absorbing chemical, irrespective of the amount of moisture which has been retained.
The apparatus described above can be use and regenerated indefinitely without rapid deterioration. Although moisture is efliciently removed from air, the resistance to air flow is not great and therefore the apparatus is well adapted to equipment such as hair dryers.
Iclaim:
In apparatus for absorbing moisture from gases like air, a plurality of rope-like elements, each of said elements being formed of asbestos fiber carrying a moisture absorbing chemical having the property of deliquescence, a supporting wire engaging about each of said elements, and a supporting frame for said elements to which the ends of said wires are attached, said elements being disposed within the frame whereby passages are formed between the elements for flow of air.
