The invention relates to a vacuum cleaner (100) in which drawn-in particle-laden air flows between an inlet nozzle (3) and a hole (119) communicated with a suction chamber (60). The vacuum cleaner is characterised in that it includes a water/air separator (1) disposed between an upstream pipe (2) and suction means, which can direct the gaseous phase into the suction chamber (60) and the particles into a container (22). The invention also relates to a heating body (201) built into the vacuum cleaner (100) and characterised in that it comprises a filament embedded in ceramic materials and a spray chamber (135) formed by a helical space between two bodies or casings (134; 137) nested inside one another, at least one of said bodies or casings (134; 137) taking the form of a ceramic body containing an embedded metal filament (130; 140).

Abrégé

The invention concerns a liquid-gas mixing device, forming a safety valve, designed to be incorporated in a gas cleaning installation comprising a liquid tank (4), an inlet (1) feeding gas flow to be cleaned and an outlet (7) via which the gas is evacuated. The invention is characterized in that it comprises: a tube (2) sliding about the supply inlet (1) and including a peripheral float (8) arranged around its lower end and designed to float in said tank (4), said sliding tube (2) being open in its lower part to suck in the liquid from said tank (4) by venturi effect and generate a mist in the expansion region (5); a mixing chamber (6) interposed between said sliding tube (2) and said outlet (7), and designed to channel the flow of said mist towards the bottom of said tank (4).
