Description

Technical Field

[0001] The invention relates to the technical field of sealing equipment, in particular to a mechanical sealing equipment of sulfonyl isocyanate. Background Art

[0002] As a specific chemical substance, sulfonyl isocyanate may require specific mechanical sealing equipment in industrial production to ensure the safety and efficiency of its production process. Sulfonyl isocyanate (such as chlorosulfonyl isocyanate) reacts violently when it comes into contact with water to produce aminosulfonic acid, hydrogen chloride and carbon dioxide. This property shows that sulfonyl isocyanate is not only insoluble in water, but also chemically reacts when it comes into contact with water. Sulfonyl isocyanate is a highly corrosive, colorless, transparent, easy-flowing liquid that is toxic and strongly irritating to the respiratory tract and skin. These properties further support the view that it is insoluble in water. Due to the corrosiveness and reactivity of sulfonyl isocyanate, it should be stored and transported in polyethylene containers to ensure safety. Sulfonyl isocyanate is insoluble in water and reacts violently when it comes into contact with water. When using and storing this compound, safe operating procedures should be strictly followed to avoid direct contact with water.

[0003] In the reaction of preparing p-toluenesulfonyl isocyanate and similar compounds, it is usually necessary to carry out the reaction under an atmosphere of inert gas (such as argon or nitrogen) to keep the oxygen content in the reactor low. Certain functional groups of sulfonyl isocyanate (such as the N=C part of isocyanate) may react chemically with other substances during the reaction. Using inert gas as a protective gas can avoid these unnecessary reactions. It can ensure that the sulfonyl isocyanate reacts in a stable environment, improving the reaction efficiency and product purity. Sulfonyl isocyanate can be isolated using inert gas during the reaction. This helps to protect the sulfonyl isocyanate from interference from other substances in the air and ensure that the reaction is carried out in a stable environment.

[0004] In the production process of sulfonyl isocyanate, the sealing problem between the machine bodies has always been a technical difficulty. The traditional sealing method often has problems such as poor sealing effect and easy leakage, which seriously affects the continuity of the production process and product quality. At the same time, it also increases the safety risk caused by the leakage of sulfonyl isocyanate. To this end, we provide a mechanical sealing device for sulfonyl isocyanate.
