Description

The The invention relates to a device for storing different ones Liquids in rotational layers. The liquids may be in their temperature levels and / or in differ in their biological and / or chemical composition.

Out known in the art are devices containing liquids, mainly waters, in a store in layers store. These are different Strömungsformer at the entrance or output of the memory arranged.

aim is a good and long-term separation of the different ones Waters to take them back to the store when needed without being mixed.

Also known in the art are devices containing liquids set in rotation for better mixing.

That's how it describes DE 197 51 730 A1 a device which mixes and cleans viscous substances through a mixing device by rotation.

DE 10 2004 017 443 B3 describes methods and apparatus for stirring different liquids over a rotating magnetic field for the purpose of better mixing.

These Procedures all use the rotation to the obvious, so the Mixing and not for the separation of liquids.

DE 10 2004 017 532 A1 describes a device for storing different waters in layers which, for stratification, directs the water inlets to horizontally extending flow diverting elements.

DE 10 2007 032 195 A1 describes a stratified storage tank for predominantly heating water, which causes the separation of the different waters through a horizontal partition plate.

Out The prior art is still a variety of stratified storage known in different ways the flow forming the Organize shift formation in the store.

All known devices try while charging or discharging of the memory, the layer formation by a uniform, to maintain non-rotating flow.

Commonly used in the art are, for example, stratified memories which, as in US Pat 2 represented, organize the layering via flowformer made of perforated metal.

Of the Flow shaper consists of a bowl-shaped Sheet J, which is perforated with holes K and in memory L is attached to the inflow sides of the water. The Water flows while, via the supply line M in the Room over sheet J and further over the holes K in the memory L.

On This route reduces the flow velocity because of the room enlargement of the flow comprehensive limitation.

The kinetic energy of the water flowing in directly from the supply line M in the memory L via vortex formation the water would mix, is in the collection room over Sheet J and memory L reduced.

The distributed from the collecting space between sheet J and memory L over the quencher K in the memory L inflowing water has a reduced kinetic energy that is against the natural stratification, as a result of the different weight of different ones Waters, the vortex formation on a limited mixed layer reduced.

The natural stratification arises through the different, specific weights of waters at different temperature levels. Above There is lighter water with high temperature, heavier below Low temperature water.

This in 2 The process shown is reversed in the same device run through from bottom to top inflowing water at low temperature equivalent.

The Quality of the stratification determines the usable volume of storage and is thus a measure of the economy. When storing with thick mixed layers you need larger and thus more expensive storage for a corresponding useful volume.

The thickness of the mixed layer determines the memories 2 the balance between the vortex-forming kinetic energy of the water leaving the holes K and the natural stratification resulting from the weight differences of the waters. In addition, the viscosity of the liquid still acts.

All these known devices have disadvantages.

One The first disadvantage is the fact that the temperature is reduced the waters the mixed layers get bigger and bigger become. For waters that are not affected by temperature, differentiated by biological and / or chemical composition, they are not suitable.

such Waters are becoming increasingly popular for example, DHW heating with thermal disinfection of the water used. The heated to disinfection temperature Water is disinfected for a fixed time by a Layered storage managed. The waters are different not by its temperature, but by its biological Ingredients.

One second disadvantage is that at low flow through the memory at the memory output a flow geometry arises in the storage areas removed from the exit center no sufficient flow realized. It arises there undesirable stagnant water.

One Another disadvantage is the memory of such education acceptable layers even in waters with different Temperatures very large and therefore expensive Strömungsformer need.

From Based on this prior art, the invention has the object to create a device that is considerably more economical Operation in terms of both investment and operating costs Stores waters in layers.

According to the invention, this object is achieved by a device according to claim 1. Below, this device is based on the embodiment and the 1 be explained in more detail.

Of the basic idea of the solution according to the invention consists in that according to the prior art well-known view, which one for the stratification in round memories a directed in the axial direction of the memory flow with low kinetic energy, formed by flow modifier at the storage entrance, and that uses the rotation of liquids only for mixing the same use is to break.

The kinetic energy of the incoming water, the stratification in the store could be destroyed during the inflow converted into rotational energy. The inflow does not take place in the axial direction of the memory, but tangentially angled to the axis.

These Inflow creates a rotation of the inflowing Water around the storage axis and thus drives a rotation of the entire waters in the store up to the storage exit.

The device after 1 shows the corresponding Strömungsformer and its installation in the memory.

1.1 shows a sheet A with a segment cut B, a hole cutout C and opening cuts D.

This sheet A will, seen in 1.2 and 1.3 , joined at the segment B section. The result is a conical Strömungsformer with a hole C to the water inlet and openings E to the water outlet.

The openings E arise in the conical assembly of the sheet A through the angular opening cuts D whose Sheet metal content at an angle maintains its original shape.

1.4 shows the built-in Strömungsformer in the memory F. The water flows through the water inlet G through the hole C in the space between the flow former A and memory F and further via the openings E at an angle to the storage axis in the memory F.

On This distance reduces the flow velocity because of the room enlargement of the flow comprehensive limitation. The remaining kinetic energy of the water Partially for driving the rotation of the water consumed in memory.

Of the Speed difference of the opening E above inflowing water to the in the respectively similar Direction of rotating storage water is very low. This is the Low vortex formation and good and permanent rotational layers are created H of the different waters, which are towards I the exit opening of the memory F move.

The Advantages of this device are a good storage layering as well at different waters of the same temperature level, one Avoidance of stagnant water in the memory area of the memory output at low storage flow rates and a smaller one Strömungsformers. This is the area of application of this memory extended, they have a better functional quality and are more cost effective because of smaller storage and smaller flow shapers Find use.
