PATENT OFFICE.

It is known that the latent heat of distilled vapors for evaporation BEZW. to aid in the evaporation of the liquid by using this Vapors in a radiator located in the liquid respectively. Presses in capacitor, so that the temperature of these vapors increases so that they cause the evaporation of the liquid BEZW. ίο can support. , ■

Here you also have the vapors condensed in this way to preheat the Liquid used.

The. Known apparatus of this type have the drawbacks that the evaporation is not sufficiently effective, that the parts thereof cannot be easily assembled and disassembled and that they require frequent cleaning or draining.
The present apparatus avoids these inconveniences.

Fig. Ι shows a longitudinal section of an embodiment of the present apparatus.

FIG. 2 shows a cross section along the line 2-2 of FIG. 1.

Figures 3 and 4 are cross-sections of certain pipe connections.

The apparatus consists essentially of

two superimposed horizontal cylindrical containers A and B, which are surrounded by heat-insulating material α and rest on a base B ^1.

These containers respectively. Cylinder A and B

communicate with each other through an opening b . In the cylinder A there is a condensation device for the grain 40

primed distilled vapors to heat the liquid. It consists of two rows of boxes a ¹ and a ¹ , of which those of the upper row a ^{1 are provided} with projections a ^s by which they are attached to the foot of a rail a * mounted inside the cylinder A. The boxes d ² are in the. lower parts of the cylinder A and also have projections α ⁵ , which engage in any attached rail α ^Ά. These boxes a ¹ and a ¹ are connected in pairs by serpentine tubes a ¹ in that the individual boxes are held together in their position by bolts a ^s by means of nuts as shown.

Between the turns of the pipes a ¹ is a horizontally arranged heating coil C. All boxes a ^l are directly connected to one another and open at one end into a pipe d which is outside of the cylinder A in connection with a compressor D , the supply pipe of which d ^{1 is} connected to a vapor separator d ' ² which is connected to a suction pipe d ³ arranged within the housing A. The 'compressor D is expediently operated by an electric motor d ^l . .

A perforated wall d ⁵ extends across the top of the cylinder A to prevent parts of the treated liquid from being entrained. Within the lower housing B , preheaters E, F and G are arranged for preheating the liquid to be distilled, through which the hot condensed vapors respectively. the con-

70

condensed vapor and the relevant heated liquid are removed. ·

Each of these devices is expediently formed from boxes e, / and g in pairs, which are correspondingly connected by vertically arranged tubes e ¹ , / ¹ and g ¹ . These boxes, like boxes a ¹ and a ^2, are held together by bolts and have laterally protruding parts e ² , / ² , g ' ¹

ίο to accommodate pipes e ¹ , / ¹ and g ^l .

The preheater respectively. The heat exchange apparatus E is connected at its upper part to the inside of the cylinder A by a pipe e ³ which passes through the opening b and extends with its open end close to the opposite end of the cylinder A. This tube is provided with a valve to regulate the outflow of the liquid, but can also be guided into the upper part of the cylinder A , respectively. the outflow can be regulated in any way.

A tube e ⁴ goes diametrically opposite tube e ³ from the lower part of the preheater E to a suitable outlet for the liquid which has been boiled and partially evaporated.

The pipe / ³ connects the preheater F to one of the boxes <z ² , which is located at the end opposite the end at which the connection of the pipe d is made. These boxes also have a valve a ⁹ . The heating pipe C is connected to a heat source and a water separator c , from which a pipe c ¹ goes into the cylinder A , which is connected to the preheater G. The pipes / ⁴ and g ³ on the lower parts of the preheaters F and G go to places for the inclusion of distilled respectively. condensed liquid from the separator c.

The preheaters E, F and G are fastened in the container B on hook-shaped supports b ^l , which are omitted in FIG. 1 for the sake of clarity.

The drain pipe e ³ is expediently connected outside the apparatus to the water pipe / ³ by a secondary line / ⁶ (Fig. 3), which is closed ^{by a three-way valve / 7 in normal operations.}

On the pipe / ³ there is a second three-way tap / ⁸ which connects it to a pipe / ⁹ in order to draw off hot distilled water.

Likewise, the pipe e ^{4 is connected} outside the apparatus by a branch line e ⁵ with the pipe / ⁴ by means of a three-way valve e ⁶ (see FIG. 4).

To operate the apparatus, steam or another heating medium is passed into the coil C and the liquid to be evaporated is pressed into the container B through a tube b ² located in the bottom of the same. This inflowing liquid rises around the three preheaters and enters the cylinder A, in which it rises to a certain height above the boxes a ^1. The heating medium in the pipe C brings the liquid inside the cylinder A to its boiling point, whereupon, after the compressor D is started, the vapor rising from the boiling liquid is sucked out of the cylinder and into the boxes a ¹ and a ¹ and the Tubes a ^{1 is} pressed. This causes the distillation vapor which passes through the compressor to be condensed in the pipes and boxes by transferring its latent and free heat to the liquid surrounding those parts. This condensed liquid then flows through pipe / ³ to the preheater F, and since the latter is surrounded by the liquid entering container B , it gives off the heat it possesses and finally flows through pipe / ⁴ at practically the same temperature as the entering liquid.

When steam has been introduced into the heating coil C, the water condensed therein goes through the pipe c ¹ to the preheater G and from there through the pipe g ^B into a drainage channel or into a container in which it can be stored by releasing the heat as it flows through it and finally flowing out at a temperature practically the same as that of the distilled liquid in the tube / ⁴ .

It should be noted that under ordinary circumstances the liquid within the cylinder A will not be vaporized to any high degree, but ^{1 flows} steadily through the pipe e ³ and the preheater E to the discharge pipe e ⁴ , and so its during its flow Gives off heat to the fresh amount of liquid entering the container B in such a way that it leaves the apparatus at a temperature only slightly higher than that of the entering liquid.

If hot distilled water is desired, this can be obtained from pipe / ⁴ through valve / ⁸ , in which case the tap / ⁷ would have to be turned to allow some caustic to flow through the radiator F by turning tap e ⁶ is used to connect the tubes / ⁴ and e ⁶ .

Although in the foregoing the apparatus in its application to steam and water has been described, the same can, as evident, also with great advantage for

Treatment of other fluids can be applied.
