循环式电加热器

循环式电加热器是通过强迫对流的方式对流动介质进行加热的,它是把浸入式电加热器装入压力容器内组成的。工作时,用泵把流动介质泵进加热腔,进行加热。加热后的介质在加热器另一端流出,它是通过泵强制循环的一种加热方式。
The circulation type electric heater heats up the fluid in the forced convection mode.That is,the fluid is pumped into the heating chamber at one end of the heater,where it is heated,and flows out of the heater at the other end. That is a heating mode by forced.

特点:
Characteristics:

  1. 体积小,功率大,循环式加热器内部主要采用浸入式加热器,最大功率达1MW。
    Compact size,big power,Circulation heater has immersion heater inside,Max power can be 1 MW.
  2. 加热速度快,控温精度高,热效率高。
    Fast heating, high precision of tempt control and high thermal efficiency.
  3. 应用范围宽,适应性强:循环式加热器可用于防爆或普通场合,它的防爆等级可达B级和C级,它的耐压可达20MPa 。
    Wide range of application, high adaptability. Circulation type heater can be used either in normal situation or in anti explosive situation. Its protection of explosion grade can reach B or C and its pressure endurance reaches 20 MPa .
  4. 加热温度高:循环式加热器设计最高工作温度可达650℃。
    High heating temperature:circulation type heater is designed to have max empt of 650℃ .
  5. 全自动化控制:通过循环式加热器控制系统设计,可方便实现出口温度、压力、流量等参数自动控制,并可与计算机联网,实现人机对话。
    Fully automatic control:by means of control system designing for the circulation heater it is easy to effect auto control of parameters like outlet tempt,pressure,and flow rate and connect it to computer network for man/machine conversation.
  6. 寿命长,可靠性高:循环式加热器不同用途设计相应功率负荷,并采用多重保护,使得本加热器安全性和寿命大大增加。 Long working life,high reliability: circulation heater is designed to have its power load correspond to different applications and has multiple-fold protection,so that safety and working life of the heater is greatly enhanced.

    The heating of hydrocarbon including heat conducting oil,fuel oil,tar,and paraffin.
  3. 清洗机、融冰槽的加热,包括NaOH溶液及各种洗涤剂。
    Heating of cleaning machine and ice melting trough,including NaOH solution and all kinds of detergent.
  4. 空气的加热,适用于一定压力下,一些粉末干燥、化工过程及喷射干燥。
    Heating of air,suited to drying up certain powder,chemical engineering process and jet drying under certain pressure.
  5. 蒸气的加热。
    Heating of steam.
  6. 气体加热,包括H2,N2及其他气体。 Heating of gases,including H2,N2 and various kinds of inert gases.

型号定义:
The Type signifies:

注:
加热器防爆型为“XHEx”,采用不锈钢材料或碳钢,若加热温度较高时,则法兰与接线盒之间需加一个散热区。散热区的长度随加热温度高低而定,具体设计请洽本公司技术部。

Note: The anti explosive type in XH heater series is "XHEx" and it is made of stainless steel or carbon steel.If heating tempt is the range of 100℃-200℃,a heat diffusion sector of 100 will have to be added between flange and terminal connection box,whose dimension shall be A+ 100.If heating tempt is higher the heat diffusion sector will have to be longer.Insulation material and thickness will depend on the user's media tempt and user requirement. For specifics of the design please consult our technical dept.

循环式加热器规格选型可见本公司样册。当然,循环式加热器的规格选型不是唯一的,例如根据某一额定功率和功率高密度来选择加热器,你可以选择法兰大一点,长度短一点,也可以选择法兰小一点,长度长一点,具体的选择要根据客户的具体情况而定,我公司技术部随时为您服务。

Select the type according to our product handbook.Naturally,the selection of circulation heater specifications is not the only one.To select heater according to nominal power and power density,you may selec one with bigger flange and smaller length,or smaller flange with bigger length.Selection will have to depend on the actuality of user's situation.In any case you may be sure of the assistance from our tech dept.
