EMISSION PURIFICATION SYSTEM USING SOLID UREA AND SELECTIVE CATALYTIC REDUCTION CATALYST

摘要

PURPOSE: An emission purification system using solid urea and selective catalytic reduction catalyst is provided to replace a solid urea module in a repair shop according to maintenance periods. CONSTITUTION: An emission purification system using solid urea and selective catalytic reduction catalyst comprises a solid urea reactor(30), a spraying part(50), a selective reduction catalyst(60), and an electronic control unit(80). The solid urea reactor generates the ammonia. The spraying part connects to the solid urea reactor. The spraying part sprays the generated ammonia on the rear end exhaust pipe(20) of the solid urea reactor. The selective reduction catalyst is installed in the exhaust pipe. The selective reduction catalyst mixes nitrogen oxide with the ammonia sprayed within the exhaust pipe and restores the nitrogen and the water. The electronic control unit is connected to the solid urea reactor and the spraying part.
