Causes of the explosion of the glass lined reactor

In the production or use of glass lined reactors, improper operation often encounters explosions of glass lined reactors, which is a great hazard to equipment and personnel. Only by understanding the reasons can explosion accidents be better avoided. Here is a detailed introduction to the cause of the reactor explosion:

　　 1. The inside of the pot is an exothermic reaction vessel, and the medium in the jacket of the glass lined reactor is circulating cooling water. If the cooling water circulation system is blocked due to some reason, the heat released by the reaction in the pot cannot be absorbed in time, and the temperature rise in the pot will cause the reaction speed in the pot to accelerate and release more heat, and the reaction speed in the pot will be faster in a short time. The pressure inside the glass lined glass lined reactor can rise several times or even dozens of times. In this case, even if the inner pot has a pressure relief outlet or safety relief accessories, in fact, their pressure relief area is far from the requirements, and timely and safe pressure relief cannot be guaranteed, which may eventually cause the container to explode.

　　2. In the production process of some chemical products, the proportion, speed and timing of the feeding are controlled to ensure that the chemical reaction is in a controlled state. If the control feeding valve is damaged, the operator's operation error, the agitator suddenly stops running, etc., causing the above conditions to be damaged, it may promote the reaction speed in the pot or the local reaction speed to accelerate or the pressure to increase suddenly.

　　3. Some chemical products require production under vacuum conditions, and the reaction process must prevent contact with oxygen or other gases in the air. If air enters the pot due to damage to the seal or other reasons, the normal reaction conditions are destroyed and an accident may occur.

　　 It can be seen that explosion accidents are generally caused by improper operation. Glass lined reactors are often used in the chemical industry. The conditions for chemical reactions are relatively strict. Once the conditions are not met, some accidents will occur. Therefore, the operator must master the operation technology. Hope the above content can help you better avoid this kind of phenomenon.
