General-purpose waste water pipe with W�rmekollektor

General-purpose waste water pipe with heat spiral collector (openPR) - new waste water pipe also on the exterior into the channel wall positively let in tubing heat collector to the use of terrestrial heat and waste water waste heat within the range of channel routes.

Those widens going use of regenerativ and already existing sources of environmental waste heat in meaningful combination with conventional heat production the future development on the heating market will coin/shape. For this it applies apart from suitable long-term heat accumulator techniques also further lasting heat sources to the individual energy-mixes to find.

For alternative keeping at a moderate temperature of energetically optimized buildings the waste water waste heat a substantial, so far unused W�rmepotenzial represents beside the solar power, the terrestrial heat, and the building waste heat. Since in addition, this heat source is subject to seasonal, and technical like diurnal variation-dependent fluctuations, and which future waste water quantity and temperature due to the demographic development and the decentralization in the en and disposal rather off as if increases, cannot be spoken here of an absolutely lasting heat source. However the Potenzial is considerable. However the public sewerage system in Germany transported approx. 11 billion m3 waste water with an average temperature of 15� C. one would reduce, could this waste water warmth only by 5� C by a heat recovery theoretically an amount of heat of approx. 65 millions MWh per year be recovered and additionally used, and/or saved. This corresponds to a fuel oil quantity of 5,6 millions tons. With this quantity 12% of the buildings in Germany could be heated. At the same time one would reduce the present CO2-Ausstoss by 11 billion ton.

A technical solution must therefore be found, which uses on the one hand this large Potenzial as far as possible, however the heat customer of the monopoly of the network carriers makes independent, and which technical mentioned like seasonal fluctuations adjusts. Which lies thus more near to use as with priority the earth area present around the sewers as heat source and/or as geothermal energy stores. In this case does not become priority the waste water in the channel as before direct, i.e. actively, but one feeds the surrounding soil passively the warmth stored there extracted, which is regenerativ present on the one hand in principle in this soil depth for an unlimited period and almost constantly, i.e., on the other hand in addition, additionally over the waste water warmth free of charge additionally.

This earth area is usually covered and accordingly thermal insulated by road construction, so that this can be used apart from the pure terrestrial heat use also very well for long-term terrestrial heat storage in connection with the heat pump, if accordingly suitable channel is available an earth heat exchanger technology. In this way in the future whole road courses can be developed additionally as heat accumulators, and remain in the winters snow and ice-free. A further advantage is the fact that that past leads public duct system at each entry door and makes the utilization of heat for theoretically each wayside owner in a city on shortest way possible. Since this conception is with priority aligned to the terrestrial heat use, can be consulted for this not only as before larger channels, but also smaller channels. This comes in particular with the developments from new construction sites to carrying, if an energy saving house conception is planned there.

Technical solution:

The technical solution plans a conventional sewer pipe, which is surrounded with a heat exchanger mechanism in the range of the entire tubing extent from the outside, preferably. This heat exchanger mechanism can, sees sketches down, as helical a tubing collector (A), or as parallel multi-tubing collector in form of a capillary tube mat (B) being trained. In order to make the W�rmekollektor for the heat exchange more efficient, it should be positively tied up to the tubing body of the waste water ear, which serves with its relatively heavy measures additionally than buffers. This happens, as the collector is cast in by the factory from the outside once again e.g. into a concrete mass. That has also the advantage that the collector is protected from damage, which makes in particular the further conventional transfer possible this sewer pipe. Both heat collector forms are already well-known from other applications (concrete core keeping at a moderate temperature in the building engineering etc.) than very efficient and effective systems. Concrete pipe and heat exchanger mechanism form thus a general-purpose collector unit, which serves on the one hand as collector for the waste water collection and disposal, on the other hand in addition, at the same time than collector for the use of the waste water waste heat and terrestrial heat functioned. A duct system equipped with it makes this at the same time an enormous horizontal terrestrial heat collector net.

, Where in a channel route which can be shifted again waste water-laterally annexes are necessary, a normal waste water tubing aligner (without W�rmekollektor) can be shifted that with a locked connection for the later integration is equipped if necessary even already. Independently of it the trend goes by that waste water annexes are to only merge in the future for a better accesibility into the channel pits.

With such W�rmekollektor of equipped sewer pipes are from the outside by the color orange put on, and in this way as such clearly marked. As said, each individual sewer pipe represents a system unit with its W�rmekollektor, and is parallel attached to a return advance and return led outside of the sewer pipe, so that each adjoining owner can follow at given time this warming race. This should take place rational way at the same time with the merging of the waste water annexe. If it should come despite all precautions times to the damage of the sewer pipe and/or the W�rmekollektors, the complete system unit can be conventionally replaced. Return advance and return can be laid either huckepack on the sewer pipe, or laterally parallel in the channel route. The first mentioned execution has the advantage that the collecting lines are solidly stored, on the other hand makes possible the second execution a simpler replacement of individual sewer pipes or sections.

The variant A is used, if, as the fundamental concept plans it, primarily the terrestrial heat is to be preferably used over the full extent of the sewer pipe. The variant B is if necessary meaningful, if much waste water flows and over the lower sewer pipe half the warmth is to be extracted from this with priority. For the computation and interpretation of this system the computing procedures in support, used for energy stakes, can be used and/or modified accordingly.

Since for this preferably heatcollector-raw made of plastic is used, the entire system is maintenance-free, and can be also channel-laterally further intended maintained. The life span of the complete system corresponds to that of the sewer pipe as at most wear-endangered construction unit.
Particularly well hereby concrete pipes can be equipped, in addition, other waste water tubing kinds are applicable for this. For example cast iron pipes are today already equipped by the factory from purposes of corrosion protection with a concrete shroud.

Advantages:

� Extremely economical production

� Building & enterprise - lastingly, high performance and very economically

� Building & enterprise - as far as possible independent of the channel enterprise

� General-purpose use - waste water disposal, and heat recovery from the ground connection and waste water warmth

� Simultaneous use for the setting up and enterprise geothermal energy store (warmth + cold weather)

� Applicable with small and large channels

� Maintenance-free with unlimited durability

� Short way to the heat customer

The technology is in the prototype phase and is available for first pilot applications. For the locking development to ready for the market one and the following common international marketing look for orange depot & Exchange of system at present for suitable partners.
