To all whom t may concern Be it known that I, CHARLES Oron/AY, of
f the city, county, and State of New York,
haveV made certain new and useful Inventions Relat-ing'to Vacuum Evaporating Apparat-us, of which the following is a speciica'tion, taken in connection with the accompa-nying drawing, forming part of the same.
Thisinvention relates to evaporating ap paratus and relates especially to the construction of film type evaporators suitable .for multipleefl'ect work and comprising an inclosing shell for a number of eifects which Amay have a rectangular cross-section and be provided with partition plates separating the adjacent chambers for the diferent effects and minimizing radiation losses therefrom, each effect if desired comprising tube sheets forming a feed chamber and vapor chamber at the ends of the effect, evaporating tubes mounted in the tube sheet-s and connected into coils through which the `liquor is fed, the steam spaces being substantially opposite in the different effects to further minimize radiation losses.
In the accompanying drawings showing an' illustrative embodiment of this invention, Figure 1 is a Vertical longitudinal section; and Fig. 2 is an end elevation.
In the illustrative embodiment of this invention shown in the drawings, the inclosing shell which may be of substantially rrectangular cross-section may be formed of `the plates 81, 82 and the side plates 83, 84
suitably riveted, bolted or otherwise con- .nected and stayed to the desired extent to give the proper rigidity under operating conditions. Suitable partition plates 81, 82 may be mounted within thisinclosing shell so that each of these plates forms the common partition Wall separating the adjacent chambers 1. 2 and 3 of the different effects i in the shell'and thus greatly minimize radiation losses, since not only is each effect made just as compact as possibly consistent with the desired capacity, but also radiation from one or more of its sides is prevented, because these partition plates also form the partition wall of a similarly heated adjacent effect. Suitable tube sheets 35 may be bolted or otherwise mounted Within each of these effects to form feed and vapor chambers at the ends thereof, such for instance, as the feed chamber 7 and. vapor chamber 6 in the lower effect, the feed chamber 8 andvapor chamber 5 in the intermethe adjacent eifects are thus substantially4 opposite each other to further minimize radiation or other heat losses and the feed and vapor chambers are also opposite in the different effects, it being of course under stood that the alternate arrangement indicated in the drawing in which a feed chamber is opposite a vapor chamber in the adjacent etl'ect need not be used in all cases, so that a still more exact alinement of the various chambers in the adjacent ,effects may be secured., if desired.
Evaporating tubes of any desired description may be mounted within each of the effects and this may be convenient-ly accomplished by mounting` these tubes in the tube sheets and packing them therein in any desired way. lf desired, the relatively larger tubes, such as 13, may be used at the beginning of each evaporating coil and connected by suitable return bends, such as 30, to a number of smaller evaporating tubes 16 which gives better evaporating efficiency in some cases. Other return bends, such as 22,
feed the liquor through still other tubes,
such as 21, before it is discharged into the vapor chamber t in which suitable battles are arranged which may have the sectional construction 31, 32 indicated. Any desired feeding device may be arranged to feed the liquor which may be supplied through the liquor' supply pipe 3S) in the desired quanti ties as controlled by the valve 40 communieating with an opening 38 in the feed chamber to the various coils, and if desired suitable feed pipes 29 may be connected with,
each of the initial evaporating tubes 13 so as to supply the liquor 10 in the feed chamber thereto in the .desired uniform manner. The aperture 69 in the vapor chamber 4 communicates through the vapor pipe 68 With the aperture 67 in the steam space of the next effect to heat the coils therein. The liquor from the irst effect passes through the apertures 48` when the valves -50 are open so as to pass through the liquor pipes 74 and apertures 49 to form the lpool 11 in thefeed chamber 8. Similar feed pipes 25 feed this liquor to the `first tubes 14 of the'coils in this effect and then tln'ough the return bends v28 into a. Aseries of smaller similar tubes 20. The vapor from the' vapor chamber, 5 passes through the `apertures 65 and vapor p1pes-66 communicatingthrough the aperture 64 with the steam space of the last effect so as to heat the tubes therein, The liquor which is separated from the vapor by the sectional bailes 33, 34 passes through the apertures 37 when the valves 41 are open so as to 'pass through the liquor pipes' 73 and apertures 36 to formthe pool 12 inthe feed chamber 7. Suitable feeding devices, such as the pipes 27, may be used to feed this liquor into the evaporating tubes 15, 18 and 19 connecte'dinto coils by suitable return bends, such as 24, 26. The vapor chamber 6 may be provided withsuitable baies as indicated and the liquor may be discharged therefrom through the liquor discharge pipe 55. The vapor may be withdrawn from this chamber throu h the aperture 63 and vapor discharge pipe 62lcom-A muni'cating with a suitable jet condenser 61. A suitable valve drip pipe 45, shown in dotted lines in Fig- 1, connects the apertures 46, 47 in the adjacent steam spaces on either side of the partition 81 and a similar valve drip pipe 44 also connects the apertures 42, 43 in the steam spaces on either side of the "'partition'82. The drip discharge pipes 56,
59 may as indicated conmiunicate with the steam space of the lower eect 3 and be provided with control valves 57, 60 controlling the amount of drip entering the drip discharge pipe 58.
'The multiple eect may be mounted in any desired way and as indicated a suitable support therefor may be formed by the longitudinal and transverse I-beam's 72. It is also vdesirable to provide the ends of each effect with suitable doors in line with the evaporating-tubes and these doors 51, 52 and '53 may be conveniently'removably'secured to the end plates 85, 86 of the effect by suitable stud bolts 87. Also for convenience a suitably hinged bracket ,54 may be provided to support each door and guide it asit is swung into place at the end of the cooperating effect. In this way, the 'feed vapor chambers may be readily opened and inspected and the. tubes and connections repaired when necessary. Suitable manholes,
' such as 70, may also'be arranged in the inclosing shell at the desiredvpointsjherein.
Having described this inventionm connection with a number of illustrative forms, arrangements, 4proportions and parts there-v of, to the details of which disclosure the invention is not of course to be limited, what is claimed as new and whatv is desired'to be secured by'uLetters Patent is set forth in the appended'claims.
