主要叙述了在浸出车间对第一蒸发器出来的棉籽混合油进行脱胶、脱酸,在低温下脱除混合油中的胶溶性杂质和脂溶性杂质,避免混合油中所含的杂质经过蒸发、汽提过程中的高温作用,导致色素固化的连续精炼原理;并对工艺流程作了详细描述。经... 主要叙述了在浸出车间对第一蒸发器出来的棉籽混合油进行脱胶、脱酸,在低温下脱除混合油中的胶溶性杂质和脂溶性杂质,避免混合油中所含的杂质经过蒸发、汽提过程中的高温作用,导致色素固化的连续精炼原理;并对工艺流程作了详细描述。经混合油连续精炼后棉籽油质量指标为:酸值(KOH)0.12 mg/g,杂质0.04%,水分0.05%,色泽(25.4 mm槽)Y35 R3.8(国标三级棉籽油色泽为Y35 R8),优于国标三级棉籽油指标;皂脚干基含油28.43%,优于常规精炼中离心机分离的皂脚干基含油(38.50%);同时对工艺设计、生产操作和要求作了详细介绍,对今后混合油精炼生产及推广有一定的借鉴作用。 展开更多

With the long-term use of coal bunker, a certain amount of sticking objects will beformed on its wall, and coal mine clearing robot can replace man in clearing the bunker wall.Also, since it equip with an explosion-proof camera, the worker can determine the operationby observing the well-head monitor.Moreover, it cannot work unless it is placed in positionand supported stably, and it has three degrees of freedom: rotating, stretching, and shovelcoal.It is driven by the hydraulic and controlled by PLC.The underground coal mine clearingrobot changs the traditional clearing methods, man does not have to enter the bunker toclear it, which ensures the production safety of coal transportation. 展开更多
