一种采用液体SO3磺化生产皮革加脂剂的方法及装置
摘要：
本发明涉及一种采用液体SO3磺化生产皮革加脂剂的方法及装置。目的是提供的方法具有工艺简单的特点；该装置具有运行稳定的特点。技术方案是：一种采用液体SO3磺化生产皮革加脂剂的方法，依次包括以下步骤：1)动植物油脂磺化循环回用料进入真空喷射器；2)液体SO3按一定流量进入SO3蒸发罐；3)SO3蒸汽与油脂在真空喷射器内初步混合后，进入均质泵；4)获得动植物油脂的磺酸酯。一种采用液体SO3磺化生产皮革加脂剂的装置，该装置包括：1)动植物油脂进入真空喷射器流体入口，液体SO3输送入SO3蒸发罐，SO3蒸发罐内蒸发的SO3气体同时进入真空喷射器吸气口；2)真空喷射器出口通过管道依次连接均质泵、换热器。
摘要（英）：

The invention relates to a method and device for producing a leather fatliquoring agent by liquid SO3 sulfonation, and aims at providing the method with the characteristic of simple process and providing the device with the characteristic of high operation stability. The method has the technical scheme that the method for producing the leather fatliquoring agent by liquid SO3 sulfonation sequentially comprises the following steps that 1, animal and plant grease sulfonation circulation reuse materials enter a vacuum ejector; 2, liquid SO3 enters an SO3 evaporating tank according to a certain flow rate; 3, SO3 vapor and grease are primarily mixed in the vacuum ejector, and then enter a homogeneous pump; 4, animal and plant grease sulphonate is obtained. The device for producing the leather fatliquoring agent by liquid SO3 sulfonation is used in the following process including the steps that 1, the animal and plant grease enters a fluid inlet of the vacuum ejector, the liquid SO3 is conveyed into the SO3 evaporating tank, and the SO3 gas evaporated in the SO3 evaporating tank simultaneously enters an air suction opening of the vacuum ejector; 2, an vacuum ejector outlet is sequentially connected with the homogeneous pump and a heat exchanger through a pipeline.
