Abstract

The invention relates to an acetylene production process, and relates to the technical field of acetylene production equipment. The acetylene production process comprises the following process steps: S1, raw material treatment; S2, charging; S3, reaction; S4, cooling and impurity removal; and S5, drying and collecting. The acetylene generator comprises a generator body and a spraying device installed in the generator body, a reaction cavity is formed in the generator body, a stirring shaft is rotationally installed on the generator body, a material disc is installed on the stirring shaft in the axial direction, a connecting pipe is arranged on the stirring shaft, and an installation assembly is arranged between the connecting pipe and the stirring shaft. The spraying device comprises a water inlet assembly, a sealing assembly and water spraying assemblies, and the water spraying assemblies are located above the material trays respectively. Through the arrangement of the installation assembly and the spraying device, water can be uniformly sprayed to each material tray, so that calcium carbide raw materials on each layer of material tray can be in full contact with the water and react with the water, the reaction degree between the calcium carbide raw materials and the water is improved, and the yield of acetylene products is further improved.

Description

technical field [0001] The present application relates to the technical field of acetylene production equipment, in particular to an acetylene production process. Background technique [0002] Acetylene, molecular formula C 2 h 2 , commonly known as wind coal or calcium carbide gas, is the smallest member of alkyne compounds and is mainly used for welding metals. At room temperature, acetylene is a colorless and extremely flammable gas. [0003] The production process of acetylene mainly includes hydrocarbon cracking method, calcium carbide method and so on. According to the different methods of heat removal and water addition, the calcium carbide acetylene method can be divided into two different processes: wet method and dry method. The dry method of acetylene production is to add water to the calcium carbide to produce acetylene. At present, the dry method is mainly used in my country. Produce acetylene gas. According to the different types of reactor structure, the dr...
