Abstract: The device for neutralizing acid combustion condensates, comprises neutralizing chamber sections sequentially separated from each other in horizontal direction by a separating wall, having sieve bottoms with an interval from its base for storing a granular neutralizing agent and connected to each other, so that the sections are flowed through by the condensates from top to bottom and then bottom to top in an alternative manner, and a sensor intended for controlling a condensate pump and having a transmitter and a receiver. The chamber sections are housed in a common box-shaped container (1). The device for neutralizing acid combustion condensates, comprises neutralizing chamber sections sequentially separated from each other in horizontal direction by a separating wall, having sieve bottoms with an interval from its base for storing a granular neutralizing agent and connected to each other, so that the sections are flowed through by the condensates from top to bottom and then bottom to top in an alternative manner, and a sensor intended for controlling a condensate pump and having a transmitter and a receiver. The chamber sections are housed in a common box-shaped container (1), which is lockable by a lid (7) and has a condensate inlet (9) and a condensate outlet (10). The separating wall positioned between the chamber sections is arranged in a flow direction, so that in the case of clogging of the chamber section, a by-pass flow forms itself above or below the sieve bottoms for the condensate in the chamber section. The chamber sections are limited by longitudinal walls, which run parallel to each other and to the flow direction of the condensate, lie at a distance from one another, extend themselves between the oppositely-lying sidewalls of the container and have same height as the sidewalls, and by transverse walls, which are aligned vertical to the flow direction of the condensate and extend themselves between the longitudinal walls. The transverse walls forming a first group are arranged above the sieve bottoms and their upper edges lie below the upper edges of the longitudinal walls. The transverse walls forming a second group extend themselves up to a height from the base of the chamber section over the sieve bottoms, where the height lies below the height of the transverse wall of the first group. The transverse walls are alternatively arranged to each other. The longitudinal walls are provided with openings and/or recesses at the container sidewall or the end turned to the container sidewall at the upper side and at the lower side. The openings and/or recesses present at the upper side of the longitudinal walls form overflows, which lie in same height as the upper edges of the transverse walls of the first group. The chamber sections are combined to a rectangular block in a module-like manner. The rectangular block has two oppositely-lying sidewalls. The separating walls present between the two chamber sections in the flow direction have condensate flow openings in the form of overflow weirs, which have alternating different heights h1 and h2 greater than h1 above the sieve bottoms. The walls extend below the sieve bottoms up to the base of the chamber sections with the openings and/or overflow weirs lying in less height. A condensate outlet chamber having the condensate outlet follows to the last chamber section in the flow direction. The condensate outlet chamber is separated from the last chamber section by a partition wall, which has opening connected to the chamber section with the condensate outlet chamber in its upper region, where the opening is in the form of overflow weirs. A liquid inlet flows into a solid particle-settling chamber. A filter chamber (13) receiving an activated charcoal filter follows to the solid particle-settling chamber. A separating wall is arranged between the settling chamber and the filter chamber with an overflow weir present at its upper side. A separating wall is upstream to the first chamber section with an overflow present at the upper side of the separating wall, where a channel follows to the separating wall and guides to a liquid inlet opening lying below the sieve bottoms of the first chamber section. The device has a chamber upstream to the condensate outlet, where the chamber is sub-divided into an upper chamber section forming the condensate outlet chamber for receiving the wet-running rotor including pump wheels of a centrifugal pump and into a lower chamber section for receiving the stator of the centrifugal pump. A separator is present between the upper and the lower chamber sections and has a bottom section, which lies above the level of the container base. The bottom section has a bearing element on its upper side for bearing the rotor including the pump wheels and is provided with a recess for receiving and bearing the wet-running rotor and the pump wheels. The upper chamber section has a holder for fastening a floating device equipped with a transmitter. The lower chamber has an upwardly directed chamber extension. The stator in the upper chamber section and the rotor in the lower chamber section are attached to the condensate pump. A conveying pipe of the condensate pump is connected to the condensate outlet. The condensate pump is a ball rotor pump, whose wet-current part is attached in the upper chamber section consisting of rotor and pump wheels during the stator presents itself in the area of the lower chamber section. The transmitter is fixed in the area of the upper chamber section and is fastened at a floater movable along a guide. The receiver is fixed in the area of the lower chamber section. A vibration exciter is attached in and/or at the container.
