The invention relates to a denitration reactor, an installation method thereof and an ammonia spraying denitration method, and the denitration reactor comprises a catalysis unit, a smoke inlet pipeline and an ammonia spraying grid. The catalysis unit is provided with a reaction cavity, a catalysis device is arranged in the reaction cavity, a flue gas inlet and a flue gas outlet are formed in the two opposite ends of the catalysis unit respectively, and the flue gas inlet and the flue gas outlet are both communicated with the reaction cavity. One end of the flue gas inlet pipeline is suitable for introducing flue gas to be treated, and the other end of the flue gas inlet pipeline is communicated with the flue gas inlet. The ammonia spraying grids are arranged in the cavity of the smoke inlet pipeline, the number of the ammonia spraying grids is more than two, and the more than two ammonia spraying grids are arranged along the trend of the smoke inlet pipeline. Compared with a traditional ammonia spraying mode,
