由华南工学院化机系设计的我国第一台高效合成氨热交换器已於湖北大悟化肥厂研制成功。该设备采用螺旋槽管和双弓形结构,可减小阻力降,性能良好,效果明显。已於1987年9月由化工部小合成氨设计中心站主持联合测试通过,准备进行鉴定推广。热交换器是高压换热设备,强化传热后可节 China’s first high-efficiency ammonia heat exchanger designed by South China Institute of Chemical Engineers has been successfully developed in Hubei Dawu Fertilizer Plant. The device uses spiral groove tube and double bow structure, can reduce the resistance drop, good performance, the effect is obvious. In September 1987 by the Ministry of Chemical Industry Small Ammonia Design Center Station presided over the joint test passed, ready for identification promotion. Heat exchanger is a high-pressure heat exchanger, heat transfer can be enhanced section
