Reaction recovery system for continuous synthesis of polyamide and method thereof

The invention provides a reaction recovery system for continuous synthesis of polyamide. The system comprises a multi-stage internal circulation tower reactor and a diamine recovery tower, wherein thereactor is beneficial to promote liquid phase recycle mixing in each stage of reaction unit, and the diamine recovery tower can separate and recover diamine components in mixed steam in time. The whole reaction recovery system has the advantages of high heat exchange efficiency, low energy requirement, low equipment investment and maintenance expenditure and the like. The invention further provides a continuous synthesis method of polyamide. The polyamide is synthesized in a multi-stage liquid-phase recycle mixing and pressure controllable decreasing mode. The gas phase pressure of differentreaction stages is adjusted, so that the boiling evaporation amount of water and diamine in a liquid phase and the reaction degree of polyamide salt are effectively controlled, the whole polycondensation process is carried out under the trend that the pressure is gradually reduced, the coordination and distribution of heat supply quantity in different reaction stages are facilitated, the improvement of the polymerization degree of a polyamide product is promoted, the polymerization degree of a final product reaches 10-60, and the requirements of a subsequent decompressor are reduced or eliminated.

A multi-barrel molecular sieve runner intermittent circulation dehumidification dryer

The invention discloses a multi-barrel molecular sieve wheel intermittent circulation dehumidification dryer, which comprises a multi-barrel molecular sieve wheel and an intermittent driving mechanism. The multi-barrel molecular sieve runner includes a top cover, a bottom cover and at least three dehumidification barrels, each of which is filled with granular molecular sieve desiccant; the intermittent drive mechanism includes a rotating shaft capable of intermittent rotation, a driven wheel, and a driving wheel with a lever , intermittent motor and position sensor, and the dehumidification bucket is evenly arranged on the outer periphery of the rotating shaft and fixedly connected with the rotating shaft. After adopting the above structure, each dehumidification barrel can be driven by the rotating shaft to perform intermittent regeneration-cooling-processing cycle work, which can make the air in the working circuit reach a lower dew point, and the dew point is stable and the fluctuation range is small. And the range can be adjusted. At the same time, the granular molecular sieve desiccant has sufficient regeneration, high energy utilization rate, and small equipment footprint. In addition, the regenerative cooling does not introduce outside air, and the regenerative waste heat is reused to heat the processed materials, saving energy.
