The invention relates to a technique for purifying acetylene gas with sulfuric acid and application thereof. An alkali cleaning cooling tower and a sulfuric acid purification tower are connected sequentially; the alkali cleaning cooling tower is moved before the sulfuric acid purification tower; and the sulfuric acid purification tower is formed by connecting two towers in series, wherein the primary tower is a packing tower, and the secondary tower is a packing/bubbling hood combined tower. The technique for purifying acetylene gas with sulfuric acid is suitable for technical processes for purifying and drying acetylene, and especially synthesis techniques of vinyl chloride. In the acetylene gas purification process, the acetylene gas is dried, and the drying effect is better than that of mixed freeze drying, thereby reducing the occurrence of side reaction and being beneficial to the proceeding of the synthetic reaction; and meanwhile, the invention can reduce the equipment investment and the consumption of freezing water or freezing salt water, thereby lowering the operating cost.
