Utilize energy -saving urea pyrolysis system of high temperature flue gas waste heat

The utility model provides an utilize energy -saving urea pyrolysis system of high temperature flue gas waste heat, it is main including diluting tuber pipe way, flue gas - dilution wind heat exchanger, electric heater, diluting wind bypass and pyrolysis oven etc. Still be equipped with dilutent wind bypass between heat exchanger import of dilution wind and the electric heater import. The utility model provides an utilize energy -saving urea pyrolysis system of high temperature flue gas waste heat can guarantee that deNOx systems keeps under the circumstances of steady operation, effectively utilizes the required dilutent wind of high temperature flue gas heat heating urea pyrolysis, and wind mode, greatly reduced denitration system ammonia energy consumption are diluted in the natural gas, diesel oil, electric energy heating substituting or that the partial replacement is conventional. Simultaneously, can effectively adjust dilutent wind -warm syndrome degree through diluting the wind bypass to when troubles
