Good question! For industrial use I would surmise that sulfuric acid is the most used acid in the world. Still, with all the digestion going on in the world, a lot of hydrochloric acid is being used.

Hydrochloric acid is most commonly known as muriatic acid and is used to lower pH in pools
Most of the sulphur produced is used to produce sulphuric acid, H2SO4, the most important manufactured chemical in the world. Sulphuric acid has many uses, including for the synthesis of fertilisers and polyamides. It is used in batteries ("battery acid").
