The working principle of a reactor and a detailed explanation

Check whether the reactor, agitator, rotating parts, auxiliary equipment, indicating instruments, safety valves, pipelines, and valves meet safety requirements.

Check whether the water, electricity, and gas systems meet safety requirements.

Relevant safety guidelines for the operation

1. Regularly check the operating condition of the reactor vessel, and stop and inspect it immediately if any abnormalities are detected.

2. Before opening the steam valve, first open the vent valve and then the inlet valve. The steam valve should be opened slowly to preheat the jacket gradually and increase the pressure step by step. The pressure inside the jacket must not exceed the specified value.

3. When cleaning titanium-epoxy equipment, do not use alkaline solutions to scrub the reactor, and take care not to damage the enamel coating.

4. Before adding the material, first start the agitator. Only when the agitator is running smoothly without any unusual noises should you add the material into the reactor. The amount of material added must not exceed the process requirements.

5. For liquid-ring vacuum pumps, start the pump before supplying water; when stopping the pump, stop the pump first and then stop the water supply. Additionally, any accumulated water inside the pump should be drained out.

6. When opening the cooling water valves, first open the return water valve and then open the inlet water valve. The cooling water pressure must not be lower than 0.1 MPa nor higher than 0.2 MPa.

7. The steam valve and the cooling valve must not be opened simultaneously, and the steam pipeline must not be struck or impacted when it is carrying steam.

、Post-operation relevant safety guidelines

1. Stop stirring, disconnect the power supply, and close all valves.

2. The reaction vessel must undergo regular technical inspections in accordance with the requirements for pressure vessels. It may not be put into operation if the inspection results are unsatisfactory.

3. When cleaning the pot, you must disconnect the mixer’s power supply, hang up a warning sign, and assign someone to supervise the operation.

Next, let’s take the high-pressure reactor as an example and explain it to you in detail:

Next, let’s take the high-pressure reactor as an example and explain it to everyone in detail:

A high-pressure reactor consists of a stirrer, a reaction vessel, a transmission system, safety devices, a cooling system, a heating furnace, and other components.

Composed of parts.

The reactor vessel and the reactor lid are fabricated from a specific type of stainless steel. The reactor vessel is connected to the reactor lid via a flange and threaded joint. The reactor lid...

It is a solid plate cover, and these two parts are securely connected by nuts arranged circumferentially and fastened with main bolts.

The main sealing interface uses a double-seal design, while other sealing points generally employ flat-to-circular configurations.

The sealing configuration featuring line contact between curved surfaces, arc-shaped surfaces, and circular arc surfaces relies on the exceptionally high precision and smoothness of the contact surfaces to achieve non-…

Usually provides a good sealing effect.

The three furnace chambers are externally equipped with barrel-shaped silicon carbide heating elements. Electric heating wires are threaded through these elements, with their ends emerging from the lower side of the furnace shell and connected via wiring.

The stud is connected to the controller via an rubber-sheathed cable.

The four-link coupling consists primarily of an inner and outer magnetic ring pair with strong magnetic forces, with a pressure-bearing spacer located in between. The stirrer is driven by a servo motor.

The motor is driven via a coupling. By controlling the rotational speed of the servo motor, it is possible to control the stirring speed.

The upper part of the five spacer sleeves is equipped with a speed-sensing coil. As the integrated stirrer rotates together with the inner magnetic ring, the speed-sensing coil generates an induced electromotive force.

The potential corresponds to the stirring speed; when this potential is transmitted to the tachometer, the stirring speed can be displayed.

The six reactor vessels are equipped with pressure gauges, rupture disc safety devices, vapor-liquid phase valves, temperature sensors, and other components, allowing for easy real-time monitoring of the conditions inside the vessels.

Monitor the reaction conditions, adjust the proportion of media in the reactor, and ensure...

The seven bearings are made of stainless steel or high-strength electrographite, offering excellent wear resistance and a long maintenance interval.

A cooling water jacket is installed between the eight-magnetic coupling and the kettle lid. When the operating temperature is relatively high, cooling water should be circulated. Additionally, if the magnet steel temperature becomes too high...
