MULTIPLE EVAPORATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 753,777, dated March 1,1904.

Application filed February 17, 1903. Serial No. M3308. (No model.)

To all. whom it may concern..-

Be it known that I, WLADIMIR WITKOWICZ, a subject of the Emperor of Russia, and a resident of 30 Bolschaja Wladimirskaja, Kiew, Empire of Russia, have invented certainnew and useful Improvements in Multiple Evaporating Apparatus, of which the following is a specification.

With the systems of evaporation-stations with multiple action hitherto in use the installations are, on the one hand, very expensive, owing to the many apparatus and the long piping required, and, on the other hand, a considerable condensation takes place in the vapor-conduits, as these are to be of a large sectional area in consequence of the low pressure of the Vapors. This condensation ought also to be avoided. Attempts have already been made to construct multiple evaporators united in one apparatus; but thus far a suitable construction has not been created, as the establishment of a communication between the heating-surface and the steam-space ofv the preceding chamber in the same apparatus of fers great practical difficulties. This is now attained in a Very simple and practical manner by the new apparatus which forms the subject of the present invention and which is represented in the accompanying drawings, in'

Figure 1, in a longitudinal section, but showing the pipes of the heating-bodies in elevation, and in Fig. 2 in a cross-section taken on line 2 2 of Fig. 1, showing the heating-body in elevation, Fig. 3 showing a section through a special closure of the heating-bodies; Fig. 4, a section through the stufling-box on the first heating-body through which the steam is admitted. Fig. 5 shows a section of a heatingbody having the pipes arranged crosswise, taken on line5 5 of Fig. 6. Fig. 6 shows a side elevation of one end of a heating-body having the pipes arranged crosswise, and Fig. 7 shows a heating-body provided with horizontally-arranged pipes.

Similar letters refer to similar parts throughout the several views.

The common casing a is by means of partition-walls b b 6 divided into as many compartments as are required for the intended 5 multiple action of the evaporating-stationin the present case into four compartments for a quadruple action. The partition-walls are provided in their upper parts with holes 0 0 0, through which the steam generated in one compartment passes to the heating-body of the next compartment. For this purpose the steam is led in the steam-space of the next compartment through the corresponding steamchannels (Z and f to the steam-chamber g. The steam-channels d and f are, as can be seen from the drawings, partly formed by the wall of the apparatus itself and stand in rigid communication with the steam chamber 9, to which easy access can be had from the out side through the movable lid h andwhich has on the other side a bore, through which the socket 11 of the heating-body passes and is made air-tight against the interior of the appa ratus by the stuffing-box Z. On the opposite side the evaporating-chamber m has been provided, which is also closed off against the outside by a movable lid n and through which the heating-body is after removal of the lid n and loosening of the stuffing-box Z can be drawn out. The heating-body itself, therefore, is open in front and is made tight through flange 0 on the wall of the apparatus. Socket p serves to let off thefwaste water, socketq to let off the ammonia-gases. Socketr leads 'to the condenser. It can be seen that none of the conduits required in the apparatus need be removed if anything is to be done at the heating-body itself. If a heating-body is not tight or is to be cleaned, it is only necessary screwed tightly to the flange t, riveted to the wall of the apparatus.

Into the first heating-body the steam must of course enter from outside, for which purpose a special socket-u, Fig. 4, has been provided. Here the casing of the stufling-box'o is secured direct in the interior of the wall of the apparatus.

The socket w, extending outside, is screwed to the socket of the heatingbody, so that the latter as well as the socket w are made tight against the interior of the apparatus. heating-body from the apparatus, I need only loosen the stuffing-box and screw off the socket w, when the heating-body can be taken out the same as the others toward the other side.

In the drawings are represented heatingbodies H, with pipes P lying crosswise; but of course bundles of pipes which have on the right and left a corresponding steam-chamber may also be used. As the ratio of transmission of heat is much higher with the heatingbodies having pipes arranged crosswise, as shown in Fig. 5, than with pipes arranged horizontally, as shown in Fig. 7, the former arrangement is preferable. In eachchamber there is to be made provision for a suitable become separated and are conveyed through the channel '2 again to the bottom-space.

What I claim as my invention, and desire to secure by Letters Patent of the United States,

1. A multiple evaporating apparatus, comprising a closed vessel, a plurality of vertical partitions in said'vessel arranged transversely to the sameand extending from the bottom to the top of the vessel and having openings in the upper part of the partitions forming communication between one compartment and the next, and heating means in each of said compartments, substantially as set forth.

'2. A multiple evaporating apparatus, comprising a closed vessel, a plurality of vertical partitions in said vessel forming a plurality of compartments and having openings in the upper part of the same forming communication between one compartment and the next,a stufifing-box for each compartment, and removable heating-bodies in each of said compartments, said heating-bodies being secured at one end by the stufling-box to one side of the vessel and secured at the other end direct to the other side of the vessel, substantially as set forth.

3. A multiple evaporating apparatus, comprising a closed vessel, a plurality ofvertical partitions in said vessel forming a plurality of compartments and having openings in the upper part of the same forming communication between one compartment and the next,a stufling-box for each compartment secured to one side of the vessel, a'lid' for each compartment secured to the other-side of the vessel, heatingbodies in each of said compartments, said heat- If it is necessary toremove the' ing-bodies being secured at one end by the stuffing-box to one side of the vessel and secured at the other end by the lid to the other side of the vessel, and a chamber at the stuffing-box end of the heating-body, substantially as set forth.
