Description

间歇式感应热反应器 技术领域
本发明涉及一种间歇式感应热反应器，属于化工、食品和环境技术领域。
背景技术
众所周知，具有高磁导率的物质处于交变磁场中会产生涡流现象而产生热量，通过给电磁线圈输入交变电流或脉冲电流，使得电磁线圈的内侧或外侧产生一定的交变磁场，从而处于其中的整块导体内部会出现感应电流。
现实生活中，对于低磁导率的液态样品，比如化工技术领域内的化学溶液、食品技术领域内的液态食品以及环境技术领域内植物浸提液、有机液等，因为其相对磁导率接近于零，所以即使处于交变磁场中，也不会出现涡流现象，进而也不会出现热效应，但是，对上述液态样品的处理都需要向其中输入能量，为了实现对液态样品进行高效率的加热并在其内部完成快速的传热和传质过程，各种新的物理场辅助加热技术孕育而生，比如射频加热、微波加热、欧姆加热均可以实现对上述液态样品进行快速加热的目的。传统的感应加热技术虽然采用了交变磁场作为激励源，但只能加热高磁导率的铁基类材料，使具有高磁导率的铁基类材料出现热效应，进而通过热传导的方式将热量传递给液体样品。
且上述欧姆加热通常使用金属的极板与样品直接接触，利用电场在电导性样品内部激发出足够大的电流密度来诱导其快速生热，但会引起不良的极板间电化学反应、导致极板腐蚀或结垢、出现加工效率降低、重金属泄露和样品污染等问题。特别是在酸性和碱性环境、及大电流密度下，上述问题会立即呈现；而射频加热中极板发射的特定频率电磁波只作用于物理尺寸与该电磁波波长相当的大分子物质，样品无需与之发生直接的物理接触，所以不会出现上述问题，但是样品温升速率不及欧姆电场处理。
发明内容
为了达到既可以避免上述欧姆加热存在的问题，同时又可以使得样品快速生热的目的，本申请公开了一种新型的物理场致热反应器，通过将进样口和出样口均设置在加热管的端口位置，使得工作过程中，进样口和出样口具有相同的电势，感应电流的回路存在于磁耦合管 和加热管之间，样品在加热管中循环流动完成间歇式处理，当充分处理完成后或者处理固定时间后，将样品取出，进行下一批样品的处理。
该间歇式感应热反应器可以设定样品在其中的反应处理时间，其利用铁芯中的交变磁通对连续流的低磁导率物料或反应介质进行激励，让其自身快速生热。
本发明的第一个目的在于提供一种间歇式感应热反应器，包括：铁芯、初级线圈、磁耦合管、加热管；
其中，铁芯由软磁材料构成，所述软磁材料包括：铁基非晶、冷轧硅钢、铁镍基非晶、钴基非晶、铁基纳米晶、坡莫合晶、铁氧体；进样口和出样口均设置在加热管的端口位置，具有电导性的低磁导率反应介质在加热管中循环流动完成间歇式处理；工作过程中，进样口和出样口具有相同的电势，感应电流的回路存在于磁耦合管和加热管之间；初级线圈和磁耦合管均缠绕于铁芯上，磁耦合管与加热管相连接；所述间歇式感应热反应器包括至少两个磁耦合管、至少一个加热管。
在一种实施方式中，电源对初级线圈施加电压后，铁芯中承载的总磁通量范围为0-5Wb，铁芯的初始磁导率为1000-50000。
在一种实施方式中，加热管两端的瞬时感应电压极性相反，铁芯中的交变磁通引发磁耦合管中具有电导性的低磁导率反应介质产生出有效的电势差，加热管中的感应电流密度为1-60A/cm 2。
在一种实施方式中，加热管内径小于磁耦合管内径。
在一种实施方式中，所述加热管和磁耦合管为圆形管，且加热管截面积与磁耦合管的截面积之比为1:2～1:30。
在一种实施方式中，感应电流回路仅存在于磁耦合管和加热管之间，进样口和出样口有漏电，用于封闭式的循环流处理。
在一种实施方式中，具有电导性的低磁导率反应介质的电导率需在0.3-20S/m范围。
本发明的第二个目的在于提供一种加热装置，所述加热装置采用上述间歇式感应热反应器，所述加热装置对可流动样品进行加热。
在一种实施方式中，所述可流动样品为电导率在0.3-20S/m范围内的物质。
本发明的第三个目的在于提供一种上述间歇式感应热反应器和/或上述加热装置在热杀菌、热灭酶、热提取及催化合成中的应用。
该间歇式感应热反应器除了实现对液态样品的快速传热和传质外，绿色且无污染，适于在热杀菌、热灭酶、热提取及催化合成中运用。
该间歇式感应热反应器的核心参数为铁芯的初始磁导率以及它能承载的总磁通量Φ，铁芯中的总磁通量Φ等于铁芯中的磁通密度B和铁芯的有效导磁面积S之积，即Φ＝BS。
初级线圈和磁耦合管间的电压比例遵循法拉第电磁感应原理。加热管中的物料或反应介质阻抗Z可采用阻抗分析仪进行测试，以便根据欧姆定律推算其感应电流密度J，即I＝U/Z，J＝I/S，其中U—加热管两端的感应电压即有效电势差；I—加热管中的感应电流强度；S—加热管的截面积。
