Condensers generally have agitators to ensure uniform temperature in the condenser. The temperature control of condenser is divided into two kinds: heating up and cooling down (depending on whether the internal reaction is exothermic or endothermic). The heating up adopts steam, molten salt or other heating medium. The cooling down is generally cooling water or other medium. Whether heating or cooling, the flow control of heating or cooling medium is adopted, the valve is manually switched on and off, or the temperature display signal is controlled by the controller through automatic control. The regulating valve of heating and cooling medium is used to control the flow rate. The control rules of the automatic condenser are as follows:
1. Accurate control of chemical reaction system by heating and cooling speed blocks
2. The heat conducting medium will not absorb water vapor at low temperature
3. Thermal conductive medium will not be oxidized, discolored or browned.
There is no oil mist at high temperature.
4. Thermodynamic changes of the fast response system, no matter the drastic heat absorption or exothermic reaction, will not have the phenomenon of temperature control lag.
5. A heat conducting medium can be used at low and high temperatures, and can be used in the temperature range of - 90 ~200 ("exclusive").
6. Low cost, once and for all. 冷凝器控制温度的操作如下：
The operation of condenser temperature control is as follows:
1. Start-up operation speed should not be too fast
In the process of using condenser, the operator often acts too quickly. When the machine is just in operation, it will turn the machine to the maximum value. In fact, this method often backfires. When the machine is in the state of shutdown, it will suddenly increase the impeller to react with the material, which will cause the operating burden of the body. In this case, the condenser mixes. It is easy for the agitator to reverse, and if there was no body reverse at that time, it would cause the agitator to deform. Besides the deformation, it will also cause the temperature of the body to rise rapidly, which will destroy the mechanical properties.
2. Cooling temperature of condenser should be progressively circulated
In the long running process of condenser, it is also a reasonable phenomenon that the temperature of the kettle body rises, but in case the temperature rises to the rated temperature, it will affect the material reaction at the right time. In this case, the cooling system installed by the condenser can timely cool down under the effect of manual regulation. Another point we need to remind you is that in the cooling process, we must pay attention to the gradual cycle. Avoid temperature difference.
