In a dip-type cooler for cooling and washing flowing dust-laden hot gas, having a venturi passage which opens in a container with washing fluid therein, the edge of a feed pipe for feed of gas into the cooler, the edge of a protective tube surrounding the feed pipe and the upper edge of the venturi passage, are of such a configuration and arrangement that the diameter of the protective tube is between the diameter of the feed pipe and that of the intake of the venturi passage and the lower boundary edge of the protective tube terminates beneath the lower edge of the feed pipe and beneath the upper edge of the venturi passage, whereby wetting fluid and dust in the gas come into contact with each other in a region spaced from wall surfaces within the cooler, to avoid the formation of caked-on deposits within the cooler.
