Gas purification equipment

The invention relates to the field of gas purification, in particular to gas purification equipment which comprises a furnace body, a drying assembly, a condensation assembly, a cooling assembly and a speed change assembly, when gas needs to be purified, the gas firstly flows through the drying assembly, the drying assembly can dry other gas and intercept liquid water in the gas, then the gas passes through the condensation assembly, and the gas is cooled through the cooling assembly; the condensation assembly condenses gaseous moisture in the gas so that the gaseous moisture can be gradually converted into the liquid state, then the gas passes through the cooling assembly, the cooling assembly can further convert the gaseous moisture into the liquid state, and meanwhile the liquid moisture can be absorbed by the cooling assembly. The method has the effect of solving the problem that the quality of steel and metallurgical products is seriously influenced by adverse effects, including corrosion, condensation,
