description

The invention relates to a device with an exhaust pipe passing through several storeys of a building, to which are connected a plurality of condensing heating devices which have a burner and use the condensation heat of the water vapor contained in the exhaust gas, each of which is provided with a condensate drain having a siphon.

In such heaters, there is always the problem of removing the condensate. It is also necessary to collect and neutralize the condensate before it can be discharged into a sewer.

However, this requires a relatively high outlay on equipment and installation for each individual condensing boiler.

The aim of the invention is to avoid this disadvantage.

According to the invention, this is achieved in the device of the type mentioned at the outset in that the condensate outflows of the individual condensing heating devices open into a common downpipe, which in the region of its lower end merges into a drain provided with a further siphon, which is connected to a neutralization device.

In this way, it is not necessary to provide a separate condensate collection and, if necessary, neutralization for each individual condensing heating device, and this also results in the advantage of less effort when installing the individual condensing heating devices.

According to a further feature of the invention, it can be provided that the condensate drains of the condensing heating devices open into the exhaust pipe, which is provided at its lower end with a drain in which a siphon is arranged.

This results in a particularly simple construction of the device, although the outlets into the exhaust pipe required for each condensing boiler must be arranged at a relatively short distance.

According to another variant of the invention, it can be provided that the condensate outflows of the condensing heating devices open into a downpipe separated from the exhaust pipe, which is led into casing stones enclosing a central exhaust pipe, this downpipe merging into a drain provided with a siphon that runs parallel to an outflow of the exhaust pipe also has a siphon and opens into a pipe leading to the neutralization device.

In this way, there is a separate discharge of the condensate that precipitates from the exhaust gases and accumulates in the individual condensing heating devices. This also results in correspondingly large distances between the junctions in the exhaust pipe or in the downpipe.

According to a further feature of the invention, it can be provided that the separate downpipe is closed at its upper end, as a result of which the neutralization device is not exposed to rainwater.

Furthermore, it can be provided that the exhaust pipe is surrounded by the inner walls of casing stones to form a back ventilation with great play and the condensing devices are connected to the rear ventilation via a wall of the casing stones penetrating the air supply pipes surrounding the pipes leading to the exhaust pipe.

In this way, the individual condensing heating devices can be supplied with fresh air very easily, and it can be found with relatively little installation effort.

The invention will now be explained in more detail with reference to the drawing.

Show:

Fig. 1 shows schematically an inventive device in section and

FIG. 2 shows a cross section through the device according to FIG. 1.

In the figures, the same reference numerals denote the same details.

1 shows a device according to the invention for connecting a plurality of condensing heating devices 1 on different floors of a building. In these condensing heating devices 1, which can be designed as continuous water heaters, circulating water heaters, boilers, process water storage tanks or stoves, there is a condensation of the water vapor contained in the exhaust gases due to the extreme removal of the heat from the exhaust gases of the burners of the devices 1, the atmospheric Burners of the condensing heaters 1 are preferably operated with natural, liquid or town gas. This prevents the creation of very aggressive exhaust gases and condensates.

The condensing heating devices 1 are connected with their approximately horizontal pipes 2 for guiding the exhaust gases to an approximately vertical exhaust pipe 3 or open into the latter. This exhaust pipe 3 is held in brick walls 4 with great play, which forms a rear ventilation 11 of the exhaust pipe 2.

The fresh air supply to the individual condensing heating devices 1 takes place via the pipes 2 concentrically surrounding fresh air supply pipes 7 which pass through a wall of the casing blocks 4 and extend into the rear ventilation 11. The rear ventilation 11 is partially or completely covered at its upper end 14 in order to limit the penetration of rainwater, but to allow a sufficient inflow of fresh air.

The condensing heaters 1 are provided with condensate drains 5, in each of which a siphon 6 is arranged. These drains 5 are connected to a down pipe 8 running in a wall of the casing stones 4, the upper end 27 of which is closed.

In its lower ends 9 and 12, the exhaust pipe 3 and the downpipe 8 merge into drains 13, 15, in each of which a further siphon 6 is arranged. Drain 9 opens

downstream of the further siphons 6 into the drain 13, which leads via a manifold 10 to a neutralization device 16, in which the acidic condensate is neutralized by adding alkaline substances, for example household waste water.

For reasons of better clarity, the illustration of a condensing boiler 1 has been omitted in FIG. 2. 2 shows that the downpipe 8 is arranged on the side of the pipes 2 and 7 which pass through the wall of the casing stones 4 and which open into the centrally arranged exhaust pipe 3 or into the rear ventilation 11.

The downpipe 8 can also be arranged in the area of the rear ventilation 11.
