| 摘要 |
The invention relates to an ammonia converter (1) having at least one catalyzer bed (2) through which gas flows substantially radially and which concentrically surrounds a heat exchanger (3). An outer and/or an inner ring chamber (8, 14) is located between the converter insert outer wall (9) and the outer cylinder casing (10) of the catalyzer (2) and/or between the inner cylinder wall (15) of the catalyzer (2) and a flow-guiding cylinder (16) which surrounds the heat exchanger tube. The most even possible flow through the catalyzer bed and heat exchanger should be reached in such a way that the most even possible temperature results for the inflowing and outflowing gas streams over the circumference of the ammonia converter. This is achieved by providing at least one of the ring chambers (8, 14) with static mixers (11) for guiding the stream in a spiral manner through the ring chamber(s). |
