Introduction of high pressure reactor

2020-10-09

The high pressure reactor is a kind of chemical reactor vessel, in which the controller plays an important role in the reaction. The electronic components of the stirring control circuit are assembled on a circuit board, and the double closed loop control system has high speed regulation precision. The speed is stable and the anti-interference ability is strong.


The outer casing of the high-pressure reactor is a standard aluminum alloy case, and the upper cover can be pulled back for maintenance and maintenance. The panel is equipped with a temperature digital display, a voltmeter, a tachometer, and control switches and adjustment knobs for the operator to operate. All external leads are led out from the rear panel through the waterproof connector from the terminals in the controller.


The heating circuit of the high-pressure reactor uses a solid-state relay to regulate the pressure, so that the heating circuit tends to be simplified. The heating power can be adjusted by adjusting the “pressure regulation” knob. At the same time, the control part of the heating circuit is equipped with an intelligent digital display to make it The heating temperature is freely regulated according to the requirements of the process, and the temperature control accuracy is extremely high.


In the process of operation, the high pressure reactorneeds to constantly listen to the abnormal vibration and sound in the reaction kettle. Check to some extent whether all the inlet and outlet valves of the reactor are in good condition. If there is any problem, it must be treated in time; Whether the bolts are loose or not, and the safety guard is intact and reliable.


High-pressure reaction kettle check safety valve, explosion-proof membrane, pressure gauge, thermometer and other safety devices are accurate and sensitive, safety valve, pressure gauge has been verified, and the seal is intact, the red line of the pressure gauge is correct, and the explosion-proof membrane is inside. leak.


Some precautions and working pressure of stainless steel reactor

In the process of high-temperature cycle reaction, the stainless steel reaction kettle will definitely cause damage to the human body. In order to reduce the damage to the human body, it is effective to use heat-conducting oil as a solvent. When our stainless steel reactor is in high temperature reaction, we must first turn on the circulating pump to make the equipment slowly heat up during the heat conduction cycle. This is harmless to the equipment, and of course the harm to us will be minimal.

There are several things to note when using the stainless steel reactor.


1. In the process of using the stainless steel reaction kettle, it is necessary to close the refrigerant inlet pipe and exhaust the remaining refrigerant in the pan and the jacket to some extent. Then enter the material.


2. The stainless steel reactor must be closed during the operation of the refrigerant inlet valve, effectively draining the remaining refrigerant in the pot and the jacket, and then input the material. Start the agitator, then turn on the steam valve and the electric heating power. After reaching the required temperature, turn off the steam valve and the electric heating power. After 2 to 3 minutes, turn off the agitator.


3. After the processing of the stainless steel reactor is completed, it is necessary to effectively drain the remaining condensed water in the pot and the jacket. Rinse with warm water as soon as possible, brush off the sticky material, and then use 40 ° C ~ 50 ° C alkaline water on the inner wall of the vessel. Fully cleaned.


4. In the case of empty material in the stainless steel reaction kettle without material (heat absorption medium), steam valve and electric heating power must not be turned on. Pay special attention to the use of steam pressure, and the working pressure should not exceed the rated working pressure.


The stainless steel reactor should be inspected for contamination before it is put into operation. The inner wall of the autoclave, the stirring and the joint surface should be cleaned with ethanol, rinsed with distilled water, and then washed with cotton or silk. Ethylene wipe to prevent cross-contamination of materials.


Stainless steel reactors must be checked for smoothness of the valves before use, especially for pressure gauges and explosion-proof membrane nozzles. For the intake duct, special attention should be paid to the presence or absence of clogging. If there is material contamination or blockage, the duct and the intake branch pipe should be removed from the kettle cover and cleaned before installation.
