Description
Technical Field
The utility model relates to a nylon 6 polymerization production is with dry nitrogen gas temperature regulation system.
Background
In the polymerization production of nylon 6, the water content of the slices in the drying and slicing process is vaporized by steam heating and saturated in nitrogen, the nitrogen mixed with water content is dehydrated by a circulating fan through a spray cooling tower, and the dehydrated nitrogen is recycled to a slice drying device and circulated in the way. The spray cooling tower achieves the dehydration effect by reducing the nitrogen passing through the spray cooling tower to be lower than the temperature of water vapor condensation by virtue of circulating water output by the plate cooler. The stability of the dry section water content of direct influence of the stability of the circulating water temperature of plate cooler output, however the circulating water exchanges the cooling with the refrigerated water in plate cooler, receives the undulant influence of refrigerated water flow and refrigeration temperature great, leads to dry sliced water content unstable.
Also there is nylon 6 production with dry nitrogen gas constant temperature circulation system of section among the prior art, however its temperature measuring point sets up unreasonablely, leads to its temperature control inflexible, leads to dry sliced water content still unstable, and can have impurity in the circulating water through spray cooling tower, and it can influence follow-up production to go on to circulate promptly not handling, influences product quality stability.
