The cartridge has a condensate inlet opening and a condensate outlet opening. The cartridge is placed at least partly in the tank so that the outlet opening is below a minimum level of liquid in the tank. ## Claims ### Claim 1 A device for neutralizing acid condensates, comprising: a tub configured to collect condensates and a cartridge enclosing a reagent configured for neutralizing acids and having an inlet aperture for inlet of the condensates and an outlet aperture for the outlet of the condensates, wherein said cartridge is placed at least partly in said tub so that said outlet aperture is situated beneath a minimum level of liquid in said tub. ### Claim 2 (depends on 1) The device for neutralizing condensates according to claim 1, wherein at least a part of the reagent contained in said cartridge is placed so as to be permanently in contact with the condensates contained in the tub. ### Claim 3 (depends on 1) The device for neutralizing condensates according to claim 1, wherein at least a part of the reagent contained in said cartridge is situated above a maximum level of liquid in said tub. ### Claim 4 (depends on 1) The device for neutralizing condensates according to claim 1, wherein the device comprises a lifting device configured to lift the condensates collected in said tub so as to form a pump for lifting condensates. ### Claim 5 (depends on 4) The device for neutralizing condensates according to claim 4, said lifting device generates movements of the liquid in said tub so as to contribute to cleaning of said outlet aperture of said cartridge and/or movements of the reagent situated in proximity to said outlet aperture. ### Claim 6 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said reagent contained in said cartridge is formed by aggregates capable of reacting with the acids contained in the condensate penetrating by said inlet aperture to neutralize them. ### Claim 7 (depends on 6) The device for neutralizing condensates according to claim 6, wherein, before use of the cartridge, an average size of the aggregates, situated in a lower portion of said cartridge, is greater by at least 30% than an average size of the aggregates situated in an upper part of said cartridge. ### Claim 8 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said cartridge is placed substantially vertically in said tub, so as to enable a gravitational flow of the condensates through said cartridge. ### Claim 9 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said cartridge is fabricated at least in part out of transparent material so as to enable a visual checking of the reagent for neutralizing the acids contained by the cartridge. ### Claim 10 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said cartridge is mounted detachably on an upper wall of said tub. ### Claim 11 (depends on 10) The device for neutralizing condensates according to claim 10, wherein at least a part of the cartridge extends above a level of said upper wall. ### Claim 12 (depends on 11) The device for neutralizing condensates according to claim 11, wherein a cartridge part extending above the level of said upper wall has a wider section than a cartridge part extending beneath said upper wall. ### Claim 13 (depends on 11) The device for neutralizing condensates according to claim 11, wherein a quantity of reagent in said cartridge is such that, before use, a part of the reagent extends above the level of said upper wall. ### Claim 14 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said cartridge comprises support elements that rest on a bottom of said tub and enable said outlet aperture to be held at a distance from said bottom. ### Claim 15 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said cartridge comprises baffles that increase a path to be travelled for the condensates in contact with said reagent for neutralizing, between said inlet aperture and said outlet aperture. ### Claim 16 (depends on 1) The device for neutralizing condensates according to claim 1, wherein said cartridge is configured so as to enable the gravitational flow towards said outlet aperture of all the liquid that penetrates therein by said inlet aperture.
