The invention relates to a comprehensive utilization method of carbon dioxide gas. The method is achieved by means of a carbon dioxide production system primarily. The carbon dioxide production systemcomprises a methanol device, a lime kiln of a calcium carbide device and a lime kiln of a sodium carbonate device communicated with one another; in the production system, the methanol device, the lime kiln of the calcium carbide device and the lime kiln of the sodium carbonate device produce CO2 gas in an auxiliary manner; the generated gas is different in concentration but can be used as a raw material of the sodium carbonate device; the lime kiln of the calcium carbide device adopts a technology of a gas sleeve lime kiln, the remarkable characteristic of the technology of the gas sleeve lime kiln is generation of circular gas. Parallel calcining belts are formed in the lime kiln by materials and fuels by the circular gas, so that an annular sleeve lime kiln can produce lime with high activity; the sodium carbonate device is a multifuel combustion lime kiln and calcines lime stones and coke primarily. The primary purpose of designing the multifuel combustion kiln to calcine lime stones is to provide CO2 gas concentration of the sodium carbonate device and meet the demand of controlling the CO2 being greater than or equal to 37%.
