Abstract
The utility model relates to an exhaust noise-eliminating apparatus of an oxygenator. An enclosed cylindrical noise-eliminating cylinder; and a plurality of straight panel-shaped baffle plates are arranged in the noise-eliminating cylinder, wherein the lengths of all the baffle plates are different and the baffle plates are distributed in the noise-eliminating cylinder horizontally. Two exhaust pipes are arranged and are respectively connected to the two ends of the noise-eliminating cylinder; one of the exhaust pipes is connected with a change-over valve; and the other exhaust pipe is connected with an outputting device. The noise-eliminating cylinder is arranged in an exhausting device, so that buffering is realized when gas is exhausted; and thus the exhausting pressure during the gas exhausting is carried out is reduced, thereby reducing noises. And the noise-eliminating cylinder design meets the noise eliminating principle of a PVC noise-eliminating cylinder. Besides, the outputting device is connected to the tail end of one exhaust pipe arranged at one end of the noise-eliminating cylinder and some small air outlets are arranged in the upper circular surface of the outputting device, so that nitrogen can be scattered and outputted at the upper circular surface of the exhaust funnel after passing the noise-eliminating cylinder. Therefore, the whole apparatus has the good noise eliminating effect when gas exhausting is carried out by the oxygenator.
