Abstract: The apparatus for neutralizing acidic combustion condensates, comprises a container (1), which is closed by a lid and has a condensate inflow (9), a condensate outflow (10), a neutralization chamber (19a, 19b), which has a sieve tray (17) and is intended to hold a granular neutralizing agent, a sensor for controlling a condensate pump, and a vibration exciter (34) attached in and/or at the container. The sieve tray is supported at a distance above a container base and bounds a condensate inflow chamber, which lies beneath the neutralization chamber. The apparatus for neutralizing acidic combustion condensates, comprises a container (1), which is closed by a lid and has a condensate inflow (9), a condensate outflow (10), a neutralization chamber (19a, 19b), which has a sieve tray (17) and is intended to hold a granular neutralizing agent, a sensor for controlling a condensate pump, and a vibration exciter (34) attached in and/or at the container. The sieve tray is supported at a distance above a container base and bounds a condensate inflow chamber, which lies beneath the neutralization chamber and into which a condensate inflow opening connected to the condensate inflow issues. The neutralization chamber is followed by a condensate outflow chamber, which has the condensate outflow and is separated from the neutralization chamber by a partition, which has an opening in the upper region, where the opening connects the neutralization chamber to the condensate outflow chamber and is in the form of an overflow weir. The neutralization chamber and the condensate outflow chamber are separated into two container section arranged horizontally next to one another by a vertical partition, which is outwardly arranged from the container base and extends over a partial length of the container. The inflow opening lies below the one end of the first container section of the neutralization chamber in the area of the first chamber section of the condensate outflow chamber. The partition in the area of the second ends of the first container sections, the neutralization chamber and the condensate inflow chamber releases a passage connecting the chamber sections. The partition limiting the condensate outflow chamber lies at the end of the second chamber sections opposite to the passage. The condensate inflow discharges into a solid particle settling chamber, on which a filter chamber receiving an activated charcoal filter is followed and the neutralization chamber is turned. Another partition with an overflow weir is arranged between the settling chamber and the filter chamber. The filter chamber comprises a partition with an overflow present on the partition top side, where the partition is upstream to the neutralization chamber, and a channel follows the partition. The sieve tray has a wave-like profile. The neutralization chamber including the sieve tray is separated into several module-like neutralization boxes inserted in the container, where box walls comprise openings. The sieve tray is separated into sieve tray sections in direction of the condensate flow. The tray sections are present at a distance from each other. The first sieve tray section is upstream in the direction of flow. Separation and recirculation chambers are inserted between adjoining sieve tray sections, in such a manner that individual successive neutralization chambers and condensate inflow chambers are formed. The flowing of the condensate takes place from the respective condensate inflow chamber and then the condensate is recirculated in the area of the condensate outflow chamber. The condensate outflow chamber comprises a front wall ending with a distance of the lid, and a rear wall, whose lower end comprises an inlet in the condensate inlet chamber and whose upper end lies above the top side of the front wall. The front and rear walls have sieve or grid-shaped wall sections. Vertical guidance slits are assigned to the each condensate outflow chambers for sliding into the container and are arranged in the area of the container walls and/or the middle partition. The section of the container is separated by a base section into an upper chamber section for the reception of the wet-flow rotor including pump impeller of a centrifugal pump and into a lower chamber section for the reception of the stator of the centrifugal pump. The base section comprises bearing elements for the storage of the rotor including the pump impeller on its top side. The pressure line of the condensate pump is attached to the condensate outflow. The base section is provided with a recess for the reception and storage of the wet-flow rotor and pump impeller of a ball engine pump. The upper chamber section comprises a mounting plate for the attachment of a float device equipped with a transmitter. The lower chamber section comprises a chamber extension directed in an upward manner. The condensate pump is a ball rotor pump. The sensor comprises a float mounted with a transmitter and accommodated in the area of the upper chamber section, and a receiver accommodated in the area of the chamber section.
