Additional patent 265,676th

Patented in the German Empire on June 4, 1913. Longest duration: July 21, 1926.

The invention relates to an apparatus for carrying out the method characterized in claim 1 of patent 265676. According to the main patent, a high speed of circulation of the liquid to be treated, which is sensitive to permanent overheating, for example sugar juices, is thereby achieved achieved that the liquid in an apparatus consisting of a lower disposed heating element of a sheathed, the front of the form of front-rear inclined tube bundle, a non-heated upper body and a and consists Getting Connected clip a rear \ ^r, is only to be filled to such a height that in a state of rest it would not reach up to the upper body.

A very substantial further increase the circulation speed succeeds according to the present improvement in that the Liquid spaces are subdivided and thus each division of the liquid is only proportionate present a small passage cross-section.

Fig. 2 shows the cross section according to AB through the front end of the apparatus and

The apparatus consists of the base body 1 and the upper body 2, which are joined together in front by the connection port 3 and back through the two connecting lines 4 'and 4. ⁶ of the lower body contains a large number of inclined tubes 5 which in the front connecting chamber 6 and the rear binding chamber 8. The partition 13 is built into the front connecting chamber 6, the partition 14 is built into the front connector 3, the partition 15 into the rear chamber 8 and the partition 16 into the upper body 2, the latter only approximately to half the height of the upper body reaches up. in this AVeise the front chamber -in departments 6 ° and 6 ^b, the front piece in sections 3 'and 3 *, the upper body in fluid compartments 2 ^ffi and 2 ^NC and the rear chamber in departments 8 ^a and 8 ^Ö disassembled. The rear connecting line 4 ^tt is connected at the top to the liquid space 2 ^a , at the bottom to the chamber compartment 8 ⁶ , conversely the line 4 ⁶ at the top to the liquid space 2 ¹ ' and at the bottom to the compartment 8 ^a . The. the two lines 4 ″ and 4 ^ therefore cross each other and pass each other.

Claims (3)

The facility described works as follows: So much liquid is poured in through the nozzle iy connected to the compartment 8 ″ of the rear chamber that it reaches approximately as far as the upper body when at rest If that group of tubes 5, which connect division 8 ^a with division 6 " , is designated with 5 °, a mixture of vapor bubbles arises in the tubes 5" and division 6 ^{a of the front chamber} Liquid, which has a lower specific gravity than the bubble-free liquid. Since there is bubble-free liquid in the nozzle 4 ⁰ , which acts with its full weight, part of the mixture of liquid and vapor bubbles is in the upper body, namely in compartment 2 °, So that this liquid is not thrown over the septum 16 of the upper body, there is a 3 ″ bo above the mouth of the nozzle compartment Genes baffle ΐ8 ^α arranged, which the. Flow of the mixture of liquid and vapor bubbles still below the upper edge of the partition 16 deflects to the rear. The mixture is now spreading in the division ^2a of the upper body, wherein the vapor separates out from the liquid and the vapor in the space i ^e rises above the partition 16, while the liquid through the nozzle 4 ° in the chamber section 8 ^ and because in the department 8 ^Ö with the department 6 ^b connecting tube group 5 ⁶ arrives. This is where renewed heating takes place and thus renewed formation of a mixture of liquid and vapor bubbles, so that the process of being thrown up is also repeated. The liquid reaches the compartment 2 ^{7j of} the upper body by being deflected backwards by a curved guide plate ΐ8 ^δ still below the upper edge of the partition 16. After propagation in the department 2 ^h, the vapor separates from the liquid and the vapor enters the space above the i ^e Scheidewand'16 while the liquid ^δ back through the nozzle 4 enters the chamber section 8 · ^a. The game described is then repeated. In the highly turbulent nature of the described operations is a state very soon forth, in which in all liquid with the exception of the return line connection 4 ° and 4 ^b, a mixture of liquid and vapor bubbles is present. Since this mixture takes up more than twice the space of the first liquid filling, all heating surfaces are now flushed with such a mixture. The device shown ensures that the throwing up of the steam 65 " liquid mixture begins and is continued when only half the content of the radiator was filled with bubble-free liquid. So it seems proportionate large heating surface stimulates the circulation on a relatively small liquid weight, and because of that in each case in the apparatus The amount of mixture located is only half the cross-section of the liquid spaces for passage is released, the passage takes place at high speed. Of course, the separation into three or more divisions, rather than the decomposition may be carried out in two departments and be taken care of by a corresponding arrangement of the connecting lines for the liquid passes back into the provided with the filler neck 17 section ^8a only after three or more cycles. In the described device for achieving increased buoyancy, if the two walls of the anterior chamber 6 were arranged parallel to each other, a particularly bubble-rich mixture would accumulate at the highest point of the chamber 6, because velvet tubes deliver bubbles there, while in the lower ones Part of the chamber 6 only the bubbles developed from the lower tubes 5 pass. To eliminate this inconvenience, the front wall 19 of the chamber 6 is arranged obliquely opposite the wall 20 containing the pipe mouths, in such a way that the horizontal cross section of the chamber 6 increases towards the top. The corresponding arrangement is also made in the case of the pipe wall 21 and the rear wall 22 of the chamber 8, so that the liquid flowing back fills all the pipes 5 evenly. The horizontal cross-sections at the top at 6 'and 8' are larger than at the bottom at 6 " and 8". In this way it is achieved that all tubes are traversed at the same speed, which is important for the reason that even small differences in the flow speeds would have a harmful effect in the case of sensitive liquids and those from which excretions easily occur. '', ' Godfather τ-An Proverbs: i. Apparatus for performing the method according to claim 1 of the patent 265676 with below arranged radiator in the shape of a sheathed, of Tubular bundle inclined forward and backward and an unheated upper body, as a result. characterized that on the one hand the front and rear collecting chamber (6 and 8) for the tube bundle (5), on the other hand the lower part of the upper body (2) by one (or more) partitions (13, 15, 16) in two (or more) compartments (a and b) dismantled and these compartments are combined by crossing rear connecting stubs (4 ", 4 '*) and a front connecting stub (3) divided by a partition (14) to form a self-contained liquid path with several circulations, while the separation space ( 2 ⁰ ) for the vapors is in connection with all liquid compartments (2 ^a , 2 ^δ ) of the upper body. 2. Apparatus according to claim 1, characterized in that a curved baffle (ΐ8 ^α , ΐ8 ^δ ) is connected to each division of the front connecting piece (3), which the jet of thrown up by the action of the liquid liquid below the upper edge of the septum (16) built into the upper body deflects backwards and thereby prevents the passage of the liquid from one compartment into the next. 3. Apparatus according to claim 1, characterized in that the horizontal cross-sections of all compartments of the front and rear collecting chambers (6 and 8) from top to bottom so that the liquid flows through all tubes (5) at approximately the same speed will. 1 sheet of drawings.
