Description

Technical Field

[0001] The utility model relates to the technical field of wet acetylene generators, in particular to a water replenishing device for an acetylene generator. Background Art

[0002] Wet acetylene generators are mainly used in the polyvinyl chloride industry. As a reactor for calcium carbide and water, they react to generate acetylene gas. During the design and production of acetylene production equipment, in order to ensure safe production, the acetylene gas produced in the reactor passes through positive water seal, reverse water seal, cooling tower, and water washing tower. Part of it is sent to the purification process to remove impurities from the crude acetylene gas and supply it to users after it is qualified; part of it is sent to the acetylene gas holder. The acetylene gas holder mainly ensures the smooth delivery of acetylene gas and plays a buffering role to ensure production safety.

[0003] The wet process of producing acetylene gas mainly involves the reaction of calcium carbide and water in the reactor to generate calcium hydroxide and acetylene gas. This reaction will release a large amount of heat. If this part of the reaction heat is not removed in time, the reactor temperature and pressure will exceed the standard, making the reactor uncontrollable and posing the risk of explosion. In the normal production process, a large amount of water needs to be added to the generator. The water will take away a large amount of reaction heat to control the temperature and pressure of the generator within the normal range. However, because the acetylene generator uses a large amount of industrial water, it will cause the problem of increased water quota. Utility Model Content
