Description

油田石油集输管线石墨烯加热保温套
技术领域
本发明涉及一种油田石油集输管线加热保温装置，尤其是节约能耗而且方便安装和拆卸，并能够有效加热油田石油集输管线以防止冻结的油田石油集输管线石墨烯加热保温套。
背景技术
目前，公知的防止油田石油集输管线冻结的方法是使用高频加热设备来加热油田石油集输管线，高频加热，即感应加热是一种利用电磁感应来加热电导体的方式，会在金属中产生涡电流，因电阻而造成金属的焦耳加热。因为高频加热是使用电阻发热原理加热，因而加热效率低，而且会造成很高的能耗浪费，因此产生很高的生产成本。
查遍国内外的相关资料，发现所有相关防止油田石油集输管线冻结的加热设备和技术，大部分使用的是电阻发热原理进行加热，有如正在大规模使用的高频加热设备，造成的能耗浪费是惊人的；另外一小部分利用化石燃料燃烧提供热能加热的方法因为方案复杂，加热效率低，没有被采用。
发明内容
为了克服电阻发热原理的加热设备在解决油田石油集输管线冻结时加热效率低造成能耗的严重浪费等不足，本发明提供了一种以石墨烯为发热源的油田石油集输管线加热保温套，利用石墨烯在电场作用下产生远红外线辐射的原理来解决油田石油集输管线冻结问题。
本发明的技术方案是提供一种油田石油集输管线石墨烯加热保温套，包括贴近油田石油集输管线外壁的耐高温绝缘层，石墨烯层和电极层，耐高温陶瓷层，防水防静电保温层和外壳，按顺序紧密贴合在一起，油田石油集输管线石墨烯加热保温套由两个半圆柱部分组成，油田石油集输管线石墨烯加热保温套的两个半圆柱部分扣合在一起后可以将需要加热的石油集输管线包裹在石油集输管线石墨烯加热保温套内，在石墨烯层两端的电极层通电时，石墨烯在电场作用下，碳原子之间剧烈的摩擦与撞击产生的热能通过波长在5-14微米的远红外线以平面方式均匀地辐射出来，可以均衡的提供热量并且可以使用温控器来控制温度，有效电热能总转换率达99％以上，有效的解决了油田石油集输管线加热保温的需求，达到节约能耗的效果。
本发明专利的优点为：采用非电阻发热原理的加热方式有效地解决了油田石油集输管线加热保温的需求，节约了能耗，安装和拆卸方便，维护成本低。

具体实施方式
结合说明书附图和实施例，对本发明进行详细说明。
实施例
如图2所示，组成油田石油集输管线石墨烯加热保温套的两部分半圆管扣合在一起，从石墨烯层(2)两端的电极层(3)引出的电线(11)接入防爆温控器(13)，从防爆温控器引出的电线(11)接入电源(15)，从防爆温控器引出的感温探头(14)插入石墨烯加热保温套内紧贴着油田石油集输管线(10)外表面。
如图2和图3所示，组成油田石油集输管线石墨烯加热保温套的耐高温绝缘层(1)、石墨烯层(2)和电极层(3)、耐高温陶瓷管(4)、防水防静电保温层(5)、外壳(6)由里向外按顺序贴合在一起。
如图4所示，石墨烯层(2)紧贴着耐高温陶瓷层(4)，石墨烯层(2)两端的电极层(3)的一部分紧压着石墨烯层(2)，一部分紧贴着耐高温陶瓷层(4)。
如图1所示，封盖(7)在油田石油集输管线石墨烯加热保温套上的相对位置。
如图3所示，密封卡槽(9)的两部分的结构。
当石墨烯层(2)两端的电极层(3)接通电源(15)时，石墨烯层(2)在电场作用下，碳原子之间剧烈的摩擦与撞击持续不断的产生热能通过波长在5-14微米的远红外线以平面方式均匀地辐射出来，直接将热量传递给油田石油集输管线(10)外表面，使得油田石油集输管线(10)由外及内温度不断升高，包裹在耐高温陶瓷层(4)外侧的防水防静电保温层(5)和外壳(6)所起的保温作用可以减少向外散发而损失的热量。感温探头(14)将油田石油集输管线(10)外表面的温度持续不断地传递给防爆温控器(13)，当油田石油集输管线(10)外表面的温度达到给防爆温控器(13)预先设定的温度时，防爆温控器(13)自动断开连接电极层(3)的电路。这时，石墨烯层(2)停止辐射远红外线，油田石油集输管线(10)外表面的温度开始下降，当防爆温控器(13)通过感温探头(14)探测到油田石油集输管线(10)外表面的温度低于给防爆温控器(13)预先设定的温度时，防爆温控器(13)自动接通连接电极层(3)的电路，石墨烯层(2)在电场作用下又开始辐射出远红外线给油田石油集输管线(10)加热。以上过程周而复始，不间断的工作，就有效的解决了油田石油集输管线加热保温的需求，达到节约能耗的效果。
