width: 461px; height: 336px;"/></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">一、操作压力：</span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">小型反应釜操作压力较高。釜内的压力是化学反应产生或由温度升高而形成，压力波动较大，有时操作不稳定，突然的压力升高可能超过正常压力的几倍，因此，大部分反应釜属于受压容器、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">二、操作温度：</span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">小型反应釜操作温度较高，通常化学反应需要在一定的温度条件下才能进行，所以反应釜既承受压力又承受温度。获得高温的方法通常有以下几种：</span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">1、水加温９�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">要求温度不高时可采用，其加热系统有敞开式和密闭式两种、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">2、蒸汽加热：</span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">加热温度�?00℃以下时，可用一个大气压以下的蒸汽来加热�?00~180℃范围内，用饱和蒸汽；当温度更高时，可采用高压过热蒸汽、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">3、用其它介质加热９�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">若工艺要求必须在高温下操作或欲避免采用高压的加热系统时，可用其它介质来代替水和蒸汽，如矿物油�?75�?00℃）、联苯醚混合剂（沸点258℃）、熔盐（140�?40℃）、液态铅（熔�?27℃）等、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">4、电加热９�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">将电阻丝缠绕在反应釜筒体的绝缘层上，或安装在离反应釜若干距离的特设绝缘体上，因此，在电阻丝与反应釜体之间形成了不大的空间间隙、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">前三种方法获得高温均需在釜体上增设夹套，由于温度变化的幅度大，使釜的夹套及壳体承受温度变化而产生温差压力。采用电加热时，设备较轻便简单，温度较易调节，而且不用泵、炉子、烟囱等设施，开动也非常简单，危险性不高，成本费用较低，但操作费用较其它加热方法高，热效率�?5%以下，因此适用于加热温度在400℃以下和电能价格较低的地方、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">三、搅拌结构：</span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">在小型反应釜中通常要进行化学反应，为保证反应能均匀而较快的进行，提高效率，通常在反应釜中装有相应的搅拌装置，于是便带来传动轴的动密封及防止泄漏的问题、�/span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">四、小型反应釜的工作：</span></p><p><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">反应釜多属间隙操作，有时为保证产品质量，每批出料后都需进行清洗；釜顶装有快开人孔及手孔，便于取样、测体积、观察反应情况和进入设备内部检修、�/span></p><p><span style="font-family: arial, helvetica, sans-serif;
