·反应釜加热方式的选择

下面反应釜网的小编跟大家讨论一下反应釜加热方式的选择。

现在需要设计一反应釜

夹套加热装置,温度250℃以下,使用5立方米搪瓷反应釜,拟采用两种加热方式,一种是蒸汽加热,一种是导热油加热,有人知道两种加热方式的优缺点吗?用哪种加热方式比较实惠简单?

如果蒸汽是预热利用或者有现成的锅炉

,可以考虑。不过夹套就是高温高压了,反应釜算压力容器,需要报审等。蒸汽加热系统操作简单,升温速度快,降温方便,因为涉及到反应釜

的压力容器,所购设备须有资质厂家生产,使用单位须到相关部门备案登记,并每年还要报检,而且使用蒸汽加热温度受到局限,若使用温度在250°C,所需要的蒸汽压力要25公斤;如使用温度在200°C,所需要的蒸汽压力要15公斤左右,相对于常压设备而言,对设备的要求很高了.

250℃还是建议导热油,低压高温,还比较容易控制。虽然设备降温速度可能慢一些,但对设备没什么特殊要求,涉及不到压力容器。不过需要购置导热油炉及循环系统。

总之,二者一个是潜热,一个显热。两个系统都可以,如果是新建厂,我一般建议导热油系统。蒸汽运行维护都会麻烦和费钱。

250度以下不牵扯到高温高压,就是压力容器而已,使用蒸汽比较清洁,方便灵活;但是蒸汽热利用率低,导热油的好处就是循环利用,热利用率较高;这个时候还是应该充分考虑检修的因素,如果频繁检修是不适合用导热油的,导热油本身也很贵的,在就是反应介质会不会腐蚀管道造成导热油的泄漏等等;至于导热油的循环加热系统一般也都不会存在啥大问题;

英文:The following reaction kettle network of small series with you to discuss the reaction kettle heating mode choice.

Now need to design a reaction kettle jacket heating device, temperature 250 degrees Celsius, 5 cubic meters of enamel reaction kettle, to use two kinds of heating methods, one is steam heating, a kind of heat conduction oil heating, it is known that the advantages and disadvantages of two kinds of heating methods. Which kind of heating method is more practical and simple?

If the steam is to be used or there is a boiler, it can be considered. But jacket is the high temperature and high pressure, the reactor pressure vessel, the need to report to the trial, etc.. Steam heating system has the advantages of simple operation, fast heating speed, cooling convenient, because it relates to the pressure vessel, the purchased equipment shall be qualified manufacturers, use unit shall apply to the relevant departments for the record registration, and plus annual inspection, and the use of steam heating temperature is limited, if the temperature 250 DEG C, the steam pressure to 25 kg; such as the use of temperature at 200 DEG C, the steam pressure to about 15 kg, compared to normal pressure equipment, requirements for equipment very high.

250, it is recommended that heat conduction oil, low pressure high temperature, it is easier to control. Although the device may slow down some slow, but no special requirements for equipment, involving less than the pressure vessel. But need to purchase thermal oil heater and circulation system.

In short, the two one is latent heat, a sensible heat. Two systems can be, if it is a new factory, I generally recommend the heat conduction oil system. Operation and maintenance of steam will trouble and money.

250 degrees is not involved in the high temperature and high pressure, is the pressure vessel, the use of steam is relatively clean, convenient and flexible, but steam heat utilization is low, the use of heat, heat utilization rate is high; this time or should take full account of the factors, such as frequent maintenance is not suitable for use with heat conduction oil, in which the reaction medium will not cause the leakage of heat conduction oil, as for the heat conduction oil heating system is generally no big problem;

Above is the reaction kettle network of small series of reaction kettle heating method of choice, which is better, please release opinion!
