The invention provides a method for producing low alkali cement by using high alkali raw materials, which includes the steps of: putting the raw material limestone with an alkali equivalent about 0.80% into a dry cement rotary kiln through a normal channel for putting the raw material into the kiln; adding chlorine-containing substances into the rotary kiln at the locations of a kiln head, a kiln head fuel burner, a flue chamber at kiln tail end, a pre-decomposition kiln or a pre-burning furnace; opening holes at the bottom part of the pre-decomposition kiln and inducting the chlorine-containing smoke gas enriched in the position into a smoke dust collection system and collecting the smoke dust in the smoke gas. The method for producing low alkali cement by using high alkali raw materials uses the special property that alkali metal ions, chloride ions and sulfate ions mutually affect the melting point temperature under the high temperature coexistence condition, adds the chlorine-containing substances during the production process, and leads the chlorine in wastes to be reacted with the alkali in the raw materials by controlling the proportion between the alkali metal ions, chloride ions and sulfate ions entering the cement kiln, thereby achieving the double effects of reducing the alkali in the cement and processing high-chlorine wastes.
