For synthetic internal parts with spiral plate heat exchangers, why is the main line not allowed to be closed or the ventilation is too small during production? In the aforementioned process one, if the inner parts of the synthesis tower are equipped with a spiral plate heat exchanger structure, the ventilation design of the secondary line and the main line will generally reach a maximum of 1: 1. In this way, in the spiral plate heat exchanger, during the heat exchange process between cold air and hot air, the forces generated by the rotation of the gas flow cancel each other out in opposite directions. If the main line valve is turned down or closed, the ventilation volume of the auxiliary line is forced to increase, which lowers the temperature entering the catalyst basket and consciously increases the CO content entering the tower to increase output. At this time, the two opposing forces of the heat exchanger are unbalanced, which can easily cause the lower part of the internal parts to twist and be displaced or even damaged. This has been confirmed by production practice.
