Problems solved by technology

[0003] The internal coil structure of the low-pressure liquid nitrogen vaporizer of the synthetic ammonia plant is a mosquito-repellent double-row coil structure, and the equipment has strict requirements on the manufacturing accuracy of the coil concentricity and tube spacing. Compared with the previous single-row spiral structure, the mosquito-repellent coil The double-row coil structure is more complex and difficult to manufacture
If the manufacturing process of single-row spiral coils is adopted, not only the concentricity of the coils, the spacing between the tubes and other manufacturing precision are difficult to control, but also a set of double-row coils of mosquito-repellent coils needs to be coiled twice, and the production efficiency is greatly reduced.
