Reactor: Causes of Reactor Malfunctions

Reaction vessel Yes There are many types of mixing devices, each differing in the materials used for components such as the stirring mechanism, heating method, shaft sealing structure, overall dimensions, temperature, and pressure. Their basic characteristics are as follows:

1. Structure

Reaction vessel The structures are basically the same. In addition to the reactor body itself, there are also transmission devices, stirring equipment, and heating (or cooling) devices. These components can improve heat transfer conditions, ensure more uniform control of reaction temperature, and do not enhance mass transfer processes.

2. Work pressure

Reaction vessel The job has high work pressure. The pressure in the vessel is caused by chemical reactions or by a rise in temperature. The pressure fluctuates significantly, and sometimes the operation is unstable. A sudden increase in pressure can exceed normal pressure by several times. Therefore, most reactors are pressure vessels.

Due to Reaction vessel The cooling circulation system in the [context] has relatively high sealing requirements. However, due to various factors, malfunctions can sometimes occur. The main reasons for this phenomenon are analyzed as follows.

1. Reaction vessel Sealing failure primarily occurs in the following forms: corrosion, thermal loss, wear, and factors related to installation and operation. After removing the mechanical seal from the autoclave, the sealing surfaces showed no scratches or wear, thus ruling out any physical damage to the sealing surfaces.

2. The sealed cavity of the water kettle contains numerous crystals and scale deposits, and combined with many signs of mechanical seal failure, it is preliminarily determined that the crystallization and corrosiveness of the conveyed medium are the primary causes of the seal failure.

3. That Reaction vessel Available at It is used at high temperatures up to 200℃. Common corrosion-prone areas include the moving ring of mechanical seals, shaft sleeves, stationary rings, and stationary-ring seats. Certain corrosive materials can also come into contact with metal shaft sleeves, moving rings, stationary-ring seats, and sealing elements, leading to specific types of corrosion.
