反应釜电加热中的第一种是指反应釜自带加热装置。在反应釜的夹套里面设置电加热器,注入导热油,也有用电磁加热片的。这种加热方式的反应釜占地面积小,无需管路连接,电热器材产生的热量直接传递给反应釜,省去中间环节的热量流失,有效的提高了利用效率,环保无污染,是很多用户的首选。但是用电直接加热的反应釜耗电量比较大,对变压器是一个严峻的考验,同时,用电加热成本也是最高的,相对于用天然气加热来说,不利于企业降低生产成本;反应釜电加热的第二种方式是指反应釜本身不产生热量,要依靠外界的导热油炉、蒸汽锅炉等设备产生热量,然后通过传热介质把热量传递给反应釜。这种反应釜要有专门的地方放置一套导热油炉,然后通过管路把反应釜和导热油炉链接在一起,工作的时候先开启导热油炉,产生热量,携带热量的高温导热油沿着提前铺好的管路进入反应釜的夹套(或盘管)内,释放热量,然后再沿着回油管路回到导热油炉里面再次接受加热,这样重复的在导热油炉内吸热,在反应釜内放热,完成对反应釜的加热过程。这种加热方式可以减轻电源的压力,不至于让电压波动,但是占地面积大,要同时容纳反应釜和导热油炉两套设备,设备投资也大,毕竟导热油炉的采购、安装、运营与维护也是一笔费用,但是生产成本会降低,因为用天然气加热相对于电,费用会低一些。

The first type of reactor electric heating is the reactor with its own heating device. An electric heater is arranged in the jacket of the reaction kettle, and heat conducting oil is injected into the jacket, as well as an electromagnetic heating sheet. The reactor with this heating method covers a small area and does not need pipeline connection. The heat generated by the electrothermal equipment is directly transferred to the reactor, eliminating heat loss in the intermediate links, effectively improving the utilization efficiency, environmental protection and pollution-free, which is the first choice of many users. However, the power consumption of the reactor heated directly by electricity is relatively large, which is a severe test for transformers. At the same time, the cost of electric heating is also the highest, which is not conducive to reducing production costs compared with natural gas heating. The second way of electric heating of the reactor is that the reactor itself does not produce heat, but depends on it. External heat conducting oil furnace, steam boiler and other equipment generate heat, and then transfer heat to the reactor through heat transfer medium. This kind of reactor should have a special place to place a set of heat-conducting oil furnace, and then link the reactor with the heat-conducting oil furnace through the pipeline. When working, the heat-conducting oil furnace should be opened to generate heat. The heat-carrying high-temperature heat-conducting oil enters the jacket (or coil) of the reactor along the pipeline laid in advance to release heat. Then along the oil return pipeline back to the heat conducting oil furnace to be heated again, so that heat is absorbed repeatedly in the heat conducting oil furnace, and heat is released in the reactor to complete the heating process of the reactor. This heating method can reduce the pressure of power supply and avoid voltage fluctuation, but it covers a large area. It needs to accommodate both the reactor and the heat-conducting oil furnace, and the equipment investment is also large. After all, the purchase, installation, operation and maintenance of the heat-conducting oil furnace is also a cost, but the production cost will be reduced because of the use of natural gas. Heating costs less than electricity.
