| titleOfInvention | Double trimethylolpropane extraction system |
| abstract | The utility model provides a ditrimethylolpropane extraction system which comprises a proportioning tank, an extraction backwashing device, a recovery device, a plate-frame filtering device, a crystallization device, a discharge pump and a connecting pipeline, wherein the proportioning tank is provided with a feed inlet and a feed outlet; the batching tank comprises a stirring and mixing device and a heating and heat-preserving device; the extraction backwashing device is an extraction backwashing tower, and a packing layer and a distributor are arranged in the extraction backwashing tower. According to the utility model, the distributor and the filler layer are additionally arranged in the extraction backwashing device, so that the mixture and the backwashing liquid can be fully mixed, ditrimethylolpropane can enter the water phase from the oil phase, the oil phase and the water phase are separated, the ditrimethylolpropane is fully dissolved into the water phase, the ditrimethylolpropane is further extracted from the water phase, and the extraction efficiency and the yield are improved; in addition, an extraction backwashing device and a recovery device are arranged, the extraction backwashing device separates a water phase from an oil phase, and isooctanol enters the recovery device in an oil phase form to recover the isooctanol in the oil phase, so that the resource waste is reduced, and the pollution to the environment is avoided. |
