How to prevent glass lining carbonization phenomenon

In order to effectively prevent the carbonization phenomenon of glass-lined reactor, the key is to take a series of targeted preventive measures in advance. The carbonization problem usually originates from the solid reaction materials deposited at the bottom of the reactor, forming an adiabatic layer, which prevents the effective transfer of heat, leading to local overheating and carbonization.

Under the premise that the basic design and heating method remain unchanged, we can improve the bottom structure of the reactor to deal with this problem. The specific approach is to install an auxiliary bottom at the bottom of the reactor, which is slightly higher than the actual bottom and leaves a gap of 3 to 10 centimeters. This design makes the solid reactants, even in the absence of mixing or stirring, will be precipitated on the auxiliary bottom, rather than directly deposited on the bottom of the glass-lined reactor, thus avoiding the formation of an adiabatic layer.

The auxiliary bottom is made of high-strength glass-lined material and is designed with many small holes, the diameter of which is slightly smaller than the particle size of the reaction material. These holes facilitate heat transfer through convection between the bottom gaps, ensuring that the heat is evenly distributed throughout the kettle. The edge of the auxiliary bottom is curved downwards to provide support, and in the case of heavy loads of solid reaction material, a metal ring can be added to the bottom of the auxiliary bottom for additional support.

Therefore, before using a glass lined reactor, it is important to implement these carbonization prevention measures and follow proper operating practices. This will not only significantly reduce the risk of carbonization of the equipment, but also extend the service life of the equipment, improve productivity and safety.
