Description

The invention relates to a drainage device, as a siphon / shower channel, with heat exchanger, in particular for a sewer pipe, specified in the preamble of claim 1. Art.

Such heat exchanger devices are well known. So revealed the DE 20 2006 012 197 a Kaltwasservorwärmung when showering on waste water in which the used shower water flows in a sewer pipe, which is designed as a sleeve and the waste water flows, which is designed as a pipe.

It will discuss the special construction of the heat exchanger tube.

It is the object of the present invention to design a heat exchanger such that it is an integral part of a siphon or a shower channel, with which energy recovery during washing / showering or when using media with temperature differences is combined and achieved a much improved maintainability of the entire system can be.

This object is achieved by an integrated heat exchanger, in particular for wastewater, having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.

An inventive sequence with a heat exchanger, in particular for waste water, with at least one housing part, in particular an integrated heat exchanger, and with a siphon or a shower channel, is characterized in that the heat exchange device at least partially in the housing part, in particular the siphon or shower channel, is integrated. So while the object according to the DE 20 2006 012 197 a heat exchange device solitary, ie detached from a subsequent siphon or a shower channel is constructed, it is inventively provided to integrate the heat exchange device directly into the housing part of the siphon or the shower channel, in particular the entire component block to arrange integrated. The heat exchange device is thermally isolated from the environment. Thus, one achieves a rapid heating regardless of the temperature of the environment and no condensation. As a result, a much faster heating of the heat exchange device, for example a heat exchanger arranged in the wastewater treatment device, can be achieved with a rapid introduction of warm wastewater, as a result of which a significantly faster efficiency can be achieved with a rapid introduction. Furthermore, due to the displacement of the heat exchange device in the housing heat exchanger variants can be significantly reduced because, for example, depending on the efficiency to be achieved this has an impact on the overall heat balance of a property and future centralized systems can be avoided. Finally, in case of failure of the heat exchange device, these are replaced directly on the housing, whereas it has hitherto been necessary to expand both the bottom of the shower and the heat exchange device, for example, to get to the heat exchanger. So while the object according to the DE 11 2005 000 262 T5 a heat exchange device for sanitary facilities is shown with an air bypass pipe including a basin, it is contrary to the invention provided to keep the heat exchange device simplest and to integrate directly into the shower channel or in the sewage siphon. Air bridging pipes and other complex solutions are not necessary

Thus, an improved system is provided with a heat exchange device, by means of which an improved "cold start behavior" with optimized efficiency, a reduction of energy losses and freedom from maintenance of the heat exchange device can be achieved.

Furthermore, according to an advantageous embodiment of the invention, it is provided that the housing, in particular the siphon, comprises at least one heat exchanger arranged at this outlet, in which the heat exchange device is arranged, wherein the heat exchanger is connected to at least one outlet of the system. In a further advantageous embodiment of the invention, the heat exchange device is arranged immediately after at least one outlet of the siphon of the housing.

Due to the proximity to the drain of the system significantly better efficiencies and a fast system response can be achieved due to the elevated temperatures. By shaping the surface of the heat exchanger (deep drawing of beads or the like in the shower channel or energetically optimized design of Strömungsleitrillen the siphon), the flow velocity can be reduced, the system-side surface required increased and simultaneously the temperature capacity can be increased.

Further advantageous embodiments of the invention provide that the heat exchange device comprises at least one heat exchanger, a siphon and a device for increasing the contact surface. The heat exchanger can optionally be a plate, a tube heat exchanger or a freeform surface heat exchanger, depending on whether the heat exchange device is assigned to a shower channel or a drainage siphon. Furthermore, a device in the form of a regulating water drainage can be provided, which is mainly used by a continuous water delivery for increased heat transfer between the hot and the cold medium used.

The device for flow-optimized feedthrough in the integrated heat exchanger device may, for example, be a manifold at the inlet to the heat exchanger in combination with a corresponding diffuser, by means of which the flow can be oriented and distributed at the same time.

A further advantageous embodiment of the invention is characterized in that the heat exchange device has at least one integrally arranged on the surface of the heat exchanger surface, which is designed by their shape so that the vorbeifließende water is slowed down and thus provides the heat exchanger longer time to heat transfer , Such surfaces may be, for example, corrugations, elevations, shapes or coatings which improve the heat transfer.

In a further advantageous embodiment of the invention, the heat exchange device is designed as at least one pre-assembled module. As a result, the assembly of such a heat exchange device can be considerably simplified and shortened, since only a preassembled module of the heat exchange device still has to be delivered and installed at a construction site. Unlike other inventions (eg: DE 198 17 031 C2 . DE 11 2005 000 262 T5 ) which have greater complexity, where several components must be mounted, it is contrary to the invention provided to connect only one heat exchanger device. Furthermore, as a result, for example in a maintenance case or in the case of a defect of the heat exchange device, disassembly of the heat exchanger device embodied as a preassembled module can be considerably simplified since the heat exchange device as a whole can be dismantled from the sewage pipe without much effort.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively indicated combination but also in other combinations or in isolation, without the scope of To leave invention.

The drawing shows in:

1 a section through a sink including inlet and outlet system, on whose lower side a heat exchange device is arranged, which encloses a siphon in each case.

2 a partially sectioned perspective view of one of in 1 shown heat exchange device with a heat exchanger, a siphon with a cleaning opening and a dirt and Frischwasser- and a temperature profile.

3 a partial perspective view of a water collection system (shower channel) with an integrated heat exchange device with a surface enlargement, a water supply level, a siphon with a cleaning opening and a dirt and Frischwasser- and a temperature profile.

4 a sectional view of one of the 3 shown heat exchange device with a heat exchanger, with a cleaning opening and a dirt and Frischwasser- and a temperature profile.

A washbasin W is in a sectional view in 1 shown, wherein two valves V1 and V2 and a siphon S is respectively disposed below the washbasin W, wherein the siphon S of a heat exchanger means 1 is enclosed. The washbasin W shown here is, for example, a container for collecting water or liquids. Similarly, a shower tray or a collection basin (eg: for collecting process liquids) can serve as a collection source.

In 2 is a partially sectioned perspective view of a portion of the siphon S with a heat exchange device 1 shown. In a sequence of the partially illustrated siphon S is the drain pipe 5 shown from the sink W where the wastewater from the sink through the sewer pipe 5 redirected to the bottom B of the siphon. In otherwise flat bottom B beads are incorporated as a diverter which redirect the wastewater flow of a laminar flow in a rotary flow R. This rotary flow R creates a better circulation around the inner wall I and thus increases the temperature transition between the inner wall I of the drain pipe and the heat exchanger device 1 , By introduced preferably grooved flow optimization 7 on the inner part of the inner wall I, the flow is decelerated and at the same time supports the rotational effect R. Through the flow optimization 7 increases simultaneously the effective area of the heat exchanger device 1 , The heat exchanger device 1 contains a cold water inlet 2 with a T deflector and a pre-tempered cold water inlet 3 , The cold water inlet 2 is at a temperature level as it usually have cold water supply lines in the private and commercial sector. The pre-tempered inlet 3 , which by removing the temperature from the dirty water 5 by means of the heat exchanger, now on a significant increase in temperature compared to the inlet 2 is now delivered to the valve. In a design of the heat exchanger device for further purposes, the Temperartureingangsgröße may also be different from the cold water temperature. The inflowing through the valve V1 cold water passes through the cold water inlet 2 in the heat exchanger device 1 and is due to the preheated cold water inlet 3 delivered to the sink W. By means of the deflector T, the flow in the heat exchanger in an opposite flow to the siphon inner part with the inner wall I is added. As a result, a concern of both currents, in the wastewater as well as in fresh water, guaranteed and preferably by attached grooves for flow optimization 7 even stronger.

In this case, connections not shown here may be provided on the module, which may be connected for example via lines with different sensors P and connected via further lines to a control device or display device, not shown here.

The heat exchanger device can likewise be arranged in other regions of the siphon, one or more heat exchanger devices 1 can be integrated around or in a respective housing part or at least partially enclose this.

In 3 is a partial perspective view of a water collection system (shower channel) with an integrated heat exchange device 1 with a surface enlargement 7 , a water level, a siphon with a waste water drain 6 shown. The warmed dirty water flows along the lateral inflow areas 5 via the integrated heat exchanger device 1 to the siphon 6 and is through the flow optimization 7 braked so far that an optimal residence time of the effluent wastewater is guaranteed. About the siphon 6 there is a cover of the cleaning opening 4 which prevents a direct outflow of warm dirty water and directs it via a kind of ramp on the heat exchange device 1 , This ensures that even the dirty water flowing out here over the cover of the cleaning opening 4 to a temperature increase over the heat exchange device 1 leads. The cold water inlet 2 is near the siphon 6 and thus ensures a maximum lowering of the dirty water temperature before it reaches the siphon 6 is rinsed out. Depending on the operative area of the heat exchange device 1 can be a temperature increase of the cold water (temperature delta between the cold water inlet 2 and the preheated cold water inlet 3 ) up to 25 ° C and more.

The water collection system is modular, so that in addition a joining together of several systems to a very long collection system, each with a heat exchange device 1 and the individual components can be done. So can a long water collection system, as z. B .: is used in public baths, to be built. Thus, the output of the preheated water supply can serve as input for the next system.

In the 4 is a sectional view (AA) one of in 3 shown shower channel with an integrated heat exchange device 1 , with a cleaning opening K and a dirt and Frischwasser- and a temperature profile.

The discharged after the process dirt or process water flows along the cleaning port K through the waste water drain 5 on the heat exchange device 1 and flows along the beads 7 which were designed as flow optimization (flow slowdown) around the contact area and contact time between the dirty water or process water and the heat exchange device 1 to maximize. To minimize nucleation, the surface facing the dirty water contains a surface coating A, preferably formed from a silver ion coating or other coating to reduce nucleation. The inflowing water over the cold water inlet 2 removes the dirty water, which via the flow optimization 7 flows, much of the energy. Thus, the preheated cold water inlet 3 , which is now at a higher energy level, recover much of the otherwise drained energy that otherwise drains into the canal via the usual waste water drain.

sThe heat exchange device 1 , is protected by an insulation C to prevent condensation on the surface.

The shower channel including the heat exchange device 1 may be formed as at least one pre-assembled module, that is, that all elements of the shower channel, such as the heat exchange device 1 , the insulation C and the cover of the shower channel K can be combined in one module. In this case, connections not shown here may be provided on the module, which may be connected for example via lines with different sensors P and connected via further lines to a control device or display device, not shown here. Due to the fact that the heat exchange device 1 the indicator passes the information can be a visibility of the energy savings.

The gutter is installed according to the current state of the art and sealed by means of seals E against the environment. Subsequently, a tiling by means of adhesive F and tiles G done. Alternatively, another floor can be used. The edge area to the shower channel is closed by means of an expansion joint H.
