The stall outgoing air contains, important in this case, heat and odour particles. Both are to be removed to the greatest possible extent. A submerged pump conveys water from the collecting container to an air heater with special steel pipes, and lamellas which, in terms of material, are of less importance. The incoming air for the stall is guided through the air heater (cooler) and is heated. The cooled water is distributed to U-bowls (as illustrated in the drawing) with the aid of a water distribution system. If the U-bowls are filled with water, they overflow at given points. It falls into the bowls which are situated below and which overflow in turn etc. The water thus falls downwards, distributed over a surface, back into the collecting container, where the submerged pump is situated (circuit). The stall outgoing air is guided in the opposite fall direction through the housing with the U-bowls. The air is caused to be distributed by the bowl underside (swirls). As a result of the frequent change in direction and as a result of the distribution of the air, it is made possible that the odour particles situated in the air are absorbed by the water. Small quantities of clean water are constantly brought into the installation via a float valve, as a result of which the dirt layer which forms on the surface of the water in the collecting container can flow off.
