About heating of reaction kettle
Thread Content
I recently studied in a workshop* , I heard from the master that the original chemical unit directly used steam to heat the jacket of the reaction kettle? Use cooling water directly for cooling. And when I entered our unit, I found that everything was using soda mixers. I just want to ask everyone, what are the advantages of using the latter? I summarized 2 points myself: 1. The use of a mixer should be relatively stable in terms of temperature increase. Because water is used as the medium for melting, it is easier to control due to the specific heat of water. 2. Secondly, is it because of the safety nature? Because the cooling water and hot water are controlled by regulating valves, the outlet of the jacket pump also has a control thermometer, which can interlock the temperature. Is there anything else, please add?~~~
Whether to use steam or hot water is mainly related to the required temperature of the reactor. In some factories, the temperature required for the reactor is not very high, while other devices produce a large amount of condensate. Recovering the heat in the condensate not only saves energy, but also reduces costs. Why not do it?
It mainly depends on the requirements of the reaction process! :)
It mainly depends on the process requirements required for the reaction. Generally speaking, it is easier to control the temperature of hot water. The source of hot water can be secondary steam generated elsewhere, which is more energy-saving.
You have summarized it very well. Another point is to consider the equipment design pressure.
One more thing: In addition to the heating temperature requirements, the choice of steam or hot water for heating the jacket of the reactor is also related to the length of heating time required for the reactor. Generally, when it is required to quickly reach the specified temperature in a short time, the steam heating method is selected. ； When slow heating is required, hot water is used for heating. For reference!
The biggest advantage of using a soda-water mixer is that there is no noise, no vibration, and a special pipe-type soda-water mixer for reactor jacket heating. For specific solutions, please contact Hunan Jianhui General Radiator Manufacturing Co., Ltd. http://www.hnjianhui.cn .
