The invention relates to a neutralization device according to the preamble of claim 1

In known neutralization devices of this kind, the alkaline granulate lies on the bottom of the container. The reaction of the alkaline granulate with the acidic condensate raises the pH value of the condensate. Above a certain pH value, the metal ions contained in the condensate are precipitated in the form of metal oxide hydrates and are clearly visible as sludge. This sludge also adheres to the particles of the granulate and blocks the active surface of the granulate, so that it can no longer adequately neutralize the condensate. In addition, the sludge can lead to a blockage of the inlet and the resulting condensate can flow into the room where the condensing boiler is installed.

Another disadvantage of the known solutions is that cleaning the container is very time-consuming and the granulate must be either cleaned or replaced at relatively short intervals.

The aim of the invention is to avoid these disadvantages and to propose a neutralization device of the type mentioned at the beginning, which can be operated simply and reliably and can be easily maintained.

According to the invention, this is achieved in a neutralization device of the type mentioned at the outset by the characterizing features of claim 1.

The proposed sieve allows the sludge to settle underneath the sieve and therefore does not adhere to the particles of the granulate, so that its active surface cannot be blocked. This means that the surface of the granulate remains active and can ensure the necessary neutralization of the condensate. Blockages in the inlet can also no longer occur. In addition, the container can be cleaned very easily as only the sieve and the granulate lying on it need to be lifted out of the container in order to easily clean the bottom.

The features of claim 2 result in the advantage of a very simple design of the sieve and a long service life thereof.

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

The same reference numerals indicate the same details in both figures.

The neutralization device according to the invention has a container 1, which is provided in its lowermost area 8 with an inlet 2 for the condensate to be neutralized from a condensing boiler (not shown). There is also an outlet 3 for the neutral

ized condensate is provided, which is arranged in the uppermost area 9 of the container 1.

A sieve 5 is arranged in the container 1 at a short distance 10 from the bottom 4 of the container 1. This is designed like a basket and has walls 11 extending upwards on all four sides. An alkaline granulate 6 is held in this basket-like sieve 5, which serves to neutralize the condensate water.

A sludge chamber 7 remains under the bottom of the sieve 5, in which accumulating sludge can settle, and can be removed very easily. To do this, it is only necessary to lift the sieve 5 together with the granulate 6 held therein out of the container, after which the sludge can be easily removed from the bottom 4 of the container 1.

The sieve 5 is conveniently made of a wire mesh made of rust-resistant wires, of appropriately finely perforated perforated sheets or of perforated plastic.
