Device for desulphurization of the flue gases of a solid matter incineration plant

The present innovation relates to a device for desulphurizing the flue gases of a solid fuel incineration plant.

It is known that in the incineration of "solids Sulphurous smoke gases are produced. Up to now, these have been discharged into the outside air through the chimney. ·.

The present innovation is based on the object of a device for desulphurising the flue gases. a solid matter incineration plant that ^{: in} addition to desulphurisation of the flue gases, it also increases the efficiency of the solid matter incineration plant.

This object is achieved in that the exhaust pipes of the boiler open into a collecting space from

which a flue pipe with a fan arranged therein cd.dgl. goes out and to the a condensate collection chamber connected via a piece of tubing to the inlet side of an ion exchanger connected is.

Y Through the device-provided condensate collection chamber and their connection with an ion exchanger, it is now easily possible to cool the flue gases below their dew point, which significantly improves the effectiveness degree of a solid incineration plant achieved will. The sulphurous condensate that forms when the flue gases cool below the dew point is desulfurized by the ion exchanger, so that the now purified liquid is safe can be discharged into the sewer system.

By installing a fan or the like. a safe expulsion of the strong

cooled flue gases ensured by the chimney.

. Further features of the innovation are the subject of subclaims. . .

In the accompanying drawings, an execution ^is for the innovation shown, described in more detail in the following soft is.
; 25.It show:

Fig. 1 is a schematic representation of a solid fuel combustion plant in vertical section,

Fig. 2 is a section through the collecting space for Rauchg & se ^ n.aqh · -der. Line II - II in-Fig.

In Fig. 1, a boiler 1 is a solid fuel incineration plant shown, in which a combustion chamber 2 is arranged in the upper area. This combustion chamber 2 takes a burner, not shown, and the Flue gases produced during the combustion process are led out of the combustion chamber 2 via the bottom Deflection pipes 3 guided into an upper annulus 4 of the boiler 1, from where a large number of Exhaust pipes 5 are guided into a lower collecting chamber 6. From the said deflection pipes 3 and the exhaust pipes 5 is for the sake of clarity

The combustion chamber 2, the deflection pipes 3 and the exhaust pipe 5 are completely from the to be heated BrauO 'water washes around, so that there is a relatively large heat exchange surface. By this comparatively large heat exchanger surface, the flue gases are cooled down to below the dew point, so that A sulfur-containing condensate is deposited in the collecting space 6.

This sulfur-containing condensate is placed in a condensate collection chamber 7 · This is done in a simple manner in that the bottom 8 . the collecting chamber 6 is provided with a gradient and at the lowest point of the collecting chamber 6 a flow opening 9 connected to the condensate collection chamber 7 is brought. ·. .

A pump 10 is located in the condensate collection chamber 7 arranged that, via a ski also piece 11 with the

Input side of an ion exchanger 12 is connected. The accumulating in the condensate collection chamber 7 Sulfur-containing condensate is transferred from the pump 10 via the hose section 11 into the ion exchanger 12 pumped and desulfurized there in a known manner. The liquid () emerging from the ion exchanger 12 Speed is therefore sulfur-free and can safely be discharged through a drain hose 13 into the sewer system be directed. .

As can be seen very clearly from FIG. 1, an exhaust pipe 14 is connected to the collecting chamber 6, in which a fan 15 is installed. The exhaust pipe 14 is in turn connected to the chimney 16.

The flue gases cooled below the dew point are expelled through the chimney 16 by the fan 15.

It is advantageous to have fresh air via the fan 15 to be sucked in from the vicinity of the boiler and expelled through the chimney 16, since thereby ■ the suction effect on the flue gases to be discharged · relative can be kept low and still ensure proper discharge through the chimney 16

: keeps performing.

"25 Deviating from the illustrated embodiment • It is also possible to dispose of the sulfur-containing condensate that occurs in the condensate collection chamber 7 directly via the hose section 11 into the ion exchanger

initiate, which then inevitably occurs
would have to be attached at a lower level than the condensate collecting chamber 7. The use of the pump 10 shown in the exemplary embodiment is advantageous in that it ultimately allows the placement of the ion exchanger 12 to be freely selected.
