Description

technical field [0001] The invention relates to the technical field of calcium carbide production, in particular to a calcium carbide production line and its system and method. Background technique [0002] The calcium carbide method acetylene chemical industry emerged in early Europe. Acetylene can chemically react with various substances to derive thousands of organic compounds. It was once known as the "mother of organic synthesis industry" internationally. my country's energy structure of "less oil, less gas, and relatively rich coal" determines that calcium carbide will still play an irreplaceable important role in the future development of the national economy. In recent years, my country's calcium carbide industry has developed rapidly, and the output of calcium carbide has increased from 8.9 million tons per year in 2005 to 25.84 million tons per year in 2015. [0003] Calcium carbide is an important chemical raw material. The existing production of calcium carbide ...
