The utility model discloses a chlor-alkali system for decomposing nitrogen trichloride by ultraviolet photolysis, which is characterized in that two ultraviolet photolysis reactors are arranged on a chlorine pipeline in front of a compressor behind a chlorine drying tower in parallel, the characteristic that the nitrogen trichloride can be decomposed when meeting light is utilized, and auxiliary parts are matched to decompose the nitrogen trichloride in chlorine by ultraviolet photolysis. The equipment investment cost is low, the nitrogen trichloride removal rate is high, and the operation method is simple, safe and effective. The controller adjusts and controls the operation number of the ultraviolet lamp tubes so as to control the content of nitrogen trichloride; one ultraviolet photolysis reactor is used and the other ultraviolet photolysis reactor is standby, so that maintenance is convenient, and front and rear stop valves are convenient to isolate from the system during maintenance; the splitter plate e
