Description

Technical Field

[0001] The utility model belongs to the technical field of acetylene production, and in particular relates to an acetylene cooling device. Background Art

[0002] Acetylene is an organic compound with the chemical formula C2H2, commonly known as wind coal or calcium carbide gas. It is the smallest member of the acetylene compounds and is a colorless gas at room temperature and pressure. It is one of the important raw materials for organic synthesis and a monomer for synthetic rubber, synthetic fiber and plastic. It can also be used for oxyacetylene welding and cutting. In the process of processing and producing acetylene, acetylene needs to be cooled. Since water spraying is more economical, acetylene is often cooled by water spraying. When acetylene is cooled by water spraying, since acetylene is slightly soluble in water, part of the acetylene will be consumed after being dissolved in water during the water spraying cooling process. At the same time, when acetylene is cooled by water spraying, other gases generated during the cooling process will take away a small amount of acetylene gas when discharged. Therefore, in the long-term use process, the consumption of acetylene is relatively large. Utility Model Content
