DE4237134A1 - Multi-floor-building exhaust pipe system - has condensate drains from heater burners connected to common down-pipe - Google Patents

Abstract

The exhaust-pipe system extends through the floors of a multi-floor building, and to which heaters with gas burners in particular are connected. These utilise the condensation heat of the water vapour in the exhaust gas, and have condensate drains containing siphons. The drains (5) from the heaters (1) are connected to a common down-pipe (8), which is connected at the bottom end (9) to a drain (13) containing a further siphon (6), and preferably leading to a neutralisation unit (16). Alternatively, they lead into the exhaust pipe itself (3), which has a drain with siphon at the bottom. ADVANTAGE - Ease of installation, neutralising condensate before this reaches the sewer.

Description

The invention relates to a device with one Floors of a building penetrating exhaust pipe, on which meh rere having a burner, in particular a gas burner, the heat of condensation of the water vapor contained in the exhaust gas heating condensing heaters are connected, each with one a siphon condensate drain are provided.

With such heaters there is always the problem of removal of the condensate. It is also necessary to do that collect and neutralize falling condensate before it enters a sewer can be drained.

However, this requires one for each individual condensing boiler relatively high device and assembly costs.

The aim of the invention is to avoid this disadvantage.

According to the invention, this is mentioned in the establishment of the introduction ten Art achieved in that the condensate drains of the individual Condensing boilers open into a common downpipe, which in the Area of its lower end into one with another siphon  provided drain passes, which preferably with a neutralisa tion device is connected.

In this way, it is not necessary to Heater a separate condensate collection and possibly new provision, and this also results in the pre part of less effort when installing each Condensing heaters.

According to a further feature of the invention, that the condensate drains from the condensing heaters into the exhaust gas pipe that provide a drain at its lower end is in which a siphon is arranged.

This results in a particularly simple structure of the Facility, however, each for a condensing boiler required outlets in the exhaust pipe in a relatively ge rings must be spaced.

According to another variant of the invention, that the condensate drains of the condensing heaters in a from Down pipe separated by gas pipe leading into a central exhaust pipe enclosing jacket stones is guided, this downpipe in a drain with a siphon passes parallel to an outflow of the exhaust pipe also having a siphon runs and into a leading to the neutralization device Pipe opens.  

In this way there is a separate removal of the Exhaust pipe collecting condensate and precipitating from the exhaust gases of the condensate in the individual condensing boilers. This also results in correspondingly large distances between the Openings in the exhaust pipe or in the downpipe.

According to a further feature of the invention, that the separate downpipe is closed at its upper end, causing the neutralization device to be exposed to rain water is avoided.

It can also be provided that the exhaust pipe from the inner walls of mantle stones to form a back ventilation with great play is surrounded and the condensing boilers over a wall of the jacket stones penetrating the pipes leading to the exhaust pipe Air supply pipes are connected to the rear ventilation.

In this way, the individual condensing heaters can be very simply be supplied with fresh air, with relatively little Assembly effort that can be found.

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

It shows

Fig. 1 shows schematically a device according to the invention in section and

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

In the figures, the same reference numerals each mean the same on details.

Fig. 1 shows a device according to the invention for the connection to several condensing heating devices 1 on different floors of a building. In these condensing heaters 1 , which can be designed as a running water heater, circulating water heater, boiler, process water storage tank or oven, 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 atmospheric burners of the condensing heaters 1 are preferably operated with natural gas, liquid or city 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 mün in this. This exhaust pipe 3 is held in masonry walls 4 with great clearance, which forms a rear ventilation 11 of the gas pipe 2 .

The fresh air supply of the individual condensing heaters 1 he follows through the pipes 2 concentrically surrounding fresh air supply pipes 7 , which pass through a wall of the casing blocks 4 and reach into the rear ventilation 11 . The rear ventilation 11 is partially or completely covered at its upper end 14 at an axial distance in order to restrict 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 wide siphon 6 is arranged. The outflow 9 opens downstream of the further siphons 6 into the outflow 13 , which leads via a collecting line 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. This Fig. 2 shows that the downpipe 8 is arranged laterally through the wall of the casing stones 4 penetrating pipes 2 and 7 , which lead into the centrally arranged exhaust pipe 3 and 11 in the rear ventilation.

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