High temperature and high pressure kettle is an important laboratory equipment, usually composed of kettle body, kettle cover, heating element, pressure control system, temperature control system and other parts. Among them, the kettle body and kettle cover are usually made of high-quality stainless steel materials to ensure the strength and corrosion resistance of the equipment. Heating elements generally use electric heating rods or infrared heating methods to evenly heat the substances inside the kettle. The pressure control system and temperature control system are used to precisely control the pressure and temperature inside the kettle.
The high-temperature and high-pressure reactor adopts a rare earth coupling driver with end face, which has the characteristics of static sealing and no leakage. The main material for the kettle body is Hasloy C-276 alloy (Hastelloy C-276 alloy), and special materials such as 304, 321, 316L, 2520, stainless steel, titanium (TA2), nickel, tantalum, zirconium, Hastelloy, Monel, and PTFE lining can be made according to different medium requirements. The stirring bearing adopts corrosion-resistant stainless steel bearing, suitable for high-speed, hydrogenation catalysis, and low viscosity material stirring. The stirring blade adopts a push type stirring slurry. heat
Introduction to High Temperature and High Pressure Reactor:
(1) Definition:
High temperature and high-pressure reactors are equipment used in industry to carry out chemical reactions under high pressure. Some high-pressure reactors are equipped with stirring or heat transfer devices.
(II)Notes:
1. It should be used in a designated location and operated according to the instructions.
2. Identify the test pressure, usage pressure, and high usage temperature conditions engraved on the main container, and use them within their allowable range.
3. The pressure used by the pressure gauge should be within 1/2 of the indicated pressure. And often compare and calibrate the pressure gauge of the high-pressure reactor with the standard pressure gauge.
4. Oxygen pressure gauges should be avoided from being mixed with pressure gauges used for other gases.
5. The safety valve and other safety devices of the high-pressure reactor should use instruments that have been regularly inspected and meet the specified requirements.
(3)Basic Structure and Principle
A high-temperature and high-pressure reactor consists of a reaction vessel, a stirrer and transmission system, a cooling device, a safety device, a heating furnace, etc.
1. The kettle body and kettle cover are made of 1Cr18Ni9Ti stainless steel processing. The kettle body is connected to the flange through threads, and the kettle cover is a regular flat plate cover. The two are fastened and connected by main bolts and nuts evenly distributed in the circumferential direction.
2. The main sealing seal of the high-pressure reactor adopts A-type double line sealing, and the other sealing points adopt the sealing form of circular arc surface to plane and circular arc surface to circular arc surface line contact. By relying on the high precision and smoothness of the contact surface, a good sealing effect is achieved.
3. The kettle is equipped with a barrel shaped silicon carbide core outside, and the electric furnace wire is threaded through the core. Its end is threaded out from the lower part of the furnace shell side and connected to the controller through wiring bolts and rubber sheathed cables.
4. The high-pressure vessel cover is equipped with a pressure gauge, a rupture disc safety device, a vapor-liquid phase valve, a temperature sensor, etc., which makes it easy to monitor the reaction situation inside the vessel at any time, adjust the medium ratio inside the vessel, and ensure safe operation.
5. The coupling is mainly composed of a pair of inner and outer magnetic rings with strong magnetic force, with a pressure bearing spacer in the middle. The mixer is driven by a servo motor through a coupling. By controlling the speed of the servo motor, the purpose of controlling the stirring speed can be achieved.
6. The upper part of the spacer is equipped with a speed measuring coil. When the agitator and the inner magnetic ring rotate together, the speed measuring coil generates an induced electromotive force, which corresponds to the stirring speed. This potential is transmitted to the tachometer to display the stirring speed.
7. A cooling water jacket is installed between the magnetic coupling and the high-pressure vessel cover. When the operating temperature is high, cooling water should be supplied, and when the magnetic steel temperature is too high, demagnetization should occur.
8. The bearings are made of 1Cr18Ni9Ti stainless steel bearings or high-strength electrochemical graphite, which are wear-resistant and have a long maintenance cycle
(IV)controller
1. The shell of the high-pressure reactor adopts a standard aluminum alloy chassis, and the upper cover can be pulled out backwards for easy maintenance and repair. The panel is equipped with temperature digital display meter, voltmeter, tachometer, control switch and adjustment knob for the operator to operate and use.
2. Electrical principle: The electronic components of the mixing control circuit are assembled on a single circuit board, using a dual closed-loop control system. The high-pressure reactor has the characteristics of high speed regulation accuracy, stable speed, strong anti-interference ability, and complete protection functions such as limiting overspeed and overcurrent. Adjusting the "speed regulation" knob can change the DC voltage of the DC motor, thereby changing the motor speed and achieving the purpose of controlling the mixing speed.
3. Solid state relays (commonly known as voltage regulating blocks) are used in the heating circuit to regulate voltage, making the heating circuit simpler. By adjusting the "voltage regulating" knob, the heating power can be adjusted. At the same time, the control part of the heating circuit is equipped with an intelligent digital display meter, allowing the heating temperature to be adjusted according to the requirements of the process, and controlling the temperature accuracy * (see the temperature meter user manual for details)
4. All external leads are led out from the wiring terminals inside the controller through waterproof connectors on the rear panel.
